Replacing Siding or Windows in New Jersey: What I’d Want to Know Before I Spend the Money
By Tiffany Slowinski
There are few home projects less exciting to spend money on than windows you already have.
At least with a new kitchen, you get to stare at something pretty when it is over.
With windows, the dream is basically that they open, close, keep the weather outside and stop making the room next to them feel 12 degrees colder than the rest of the house.
Siding is slightly more fun because it can completely change how your house looks. It is also the kind of project where one estimate turns into a conversation about house wrap, trim, insulation, flashing and five other things I did not know I was supposed to have an opinion about.
I do not want to become an expert in siding or windows.
I want to know enough to make a smart decision.
Do I actually need to replace this?
This would be my first question.
A drafty room does not automatically mean every window in the house needs to go. Siding that looks tired does not necessarily mean the entire exterior has failed.
Before someone gives me a giant replacement number, I want to know what is actually wrong.
Can it be repaired? Is the problem the window itself, the installation around it or something else? Is the siding damaged or do I just hate the color?
There is a big difference between “this needs to be replaced” and “if you are planning to stay here another 15 years, this is probably the right time to replace it.”
I want the person who can explain that difference.
If I replace the windows, what am I actually buying?
Window shopping gets technical very quickly.
There are different materials, glass packages, styles, manufacturers and installation methods. Then everyone starts talking about efficiency ratings and suddenly I am pretending I know what all of the numbers mean.
I do not.
What I actually care about is much simpler.
Will these windows make the house more comfortable? Will they be easier to open and clean? Will they reduce drafts? Will they look right with the house? What maintenance will they need? How long should I reasonably expect them to last?
And I want to understand exactly what is being replaced.
Is the contractor installing a replacement window into the existing frame, or removing everything and doing a full-frame replacement? Why are they recommending one over the other for my house?
That answer matters a lot more to me than a brochure with 14 performance charts.
Will the new siding make my house look better or just newer?
This is probably the question women are actually asking.
Because technically new siding can be perfectly good and still make a beautiful house look cheap.
I would want to see completed homes that are similar to mine.
Not one perfect manufacturer photo.
Actual houses.
Show me the trim around the windows. Show me the corners. Show me how you handled the front entry, soffits and architectural details. Show me what the house looks like from the street when everything is finished.
The siding itself is only part of what you are looking at.
The details are what make the house feel polished instead of wrapped in plastic.
Vinyl, fiber cement, wood or something else?
This is where I want someone to ask me questions before giving me an answer.
How much maintenance am I willing to do?
How long do I expect to stay in the house?
What style is the house?
What does the neighborhood look like?
How important is the exact color or texture to me?
There is not one siding material that automatically makes sense for every house.
I would be suspicious of anyone who recommends the same thing before they have even looked at mine.
Should I do the siding and windows at the same time?
Maybe.
If both projects are coming soon anyway, there can be practical reasons to coordinate them. The window trim, flashing and siding all meet in the same places.
That does not mean I am signing up for a second major project because somebody tells me it is “easier while we are here.”
Show me why.
What gets done differently if I do them together? What would have to be redone later if I separate them? Is there an actual savings or just convenience?
If doing both makes sense, great.
I just want the math and the reasoning before we turn one project into two.
What happens when you take the old siding off?
This would be high on my list because houses have a funny habit of hiding expensive things.
What happens if you find rot?
What if the sheathing underneath needs repair?
What if the house wrap is missing or damaged?
Is any of that included in the quote? If not, how will additional work be priced?
I am fine with the reality that nobody can see through my walls.
I am less fine with a vague contract followed by a series of surprises once half the house is exposed.
Tell me what you can know now and what could reasonably change later.
Who is actually doing the work?
This is one I would ask directly.
Is the crew working on my house employed by the company I hired or subcontracted?
If it is subcontracted, that is not automatically a problem.
I just want to know.
Who supervises the job? Who do I call if something does not look right? Who is responsible for the workmanship warranty after the project is finished?
Your salesperson may be wonderful.
They are probably not the person who will be standing on the ladder outside your bedroom window.
Is the contractor actually registered in New Jersey?
This sounds basic, but it is worth checking.
Siding and window contractors in New Jersey are home improvement contractor businesses. The state requires them to register, and the registration number begins with 13VH.
That is a registration, not a trade license or a test of how talented someone is.
Still, I want the company doing a major exterior project on my house to exist in the state record.
One thing we found while researching this guide is that the name on a contractor’s website does not always match the legal business name in the state database. The office town can be different too.
That does not automatically mean anything is wrong.
It does mean Googling a company name is not always enough to verify it.
That is why we did it for you.
If my house was built before 1978, I would ask one more question
A lot of homes in and around Frenchtown are older.
Federal lead-safe renovation rules apply when siding or window replacement disturbs painted surfaces on homes built before 1978.
I am not asking the homeowner to become an expert in federal regulations either.
I would simply ask the contractor: Is my house old enough for the lead-safe rule to apply, and does your company have the certification required for this work?
That is a much better question to ask before the siding comes off.
What exactly is included in this quote?
This is where I slow down.
What product line are you installing?
What trim is included?
What happens around windows and doors?
Is removal and disposal of the old material included?
Who handles permits if they are needed?
What is the workmanship warranty?
What does the manufacturer warranty cover?
What could cost extra once the project begins?
If two estimates are $15,000 apart, I want to know why.
Sometimes one contractor is more expensive.
Sometimes the two contractors are not actually quoting the same job.
Those are very different things.
I care a lot about how someone explains all of this
This is probably my biggest test with any contractor.
Can you explain what my house needs without making me feel like an idiot?
Can you tell me what matters and what is optional?
Can you say, “You do not need to spend money on that right now”?
That last one earns a lot of trust with me.
I do not need the cheapest person.
I want the person whose explanation makes sense.
So how do you narrow down the list?
That is why Garden State Circle built this guide differently.
We started with companies that actually publish siding or window work in Frenchtown or the surrounding Hunterdon County area, then checked their New Jersey Home Improvement Contractor registration against the state record.
The guide currently includes 19 companies.
We show you the company name, where it says it is located, what services it publishes and what the state registration actually says.
We are not ranking them.
A state registration cannot tell you whether someone will do beautiful work. A five-star review cannot tell you whether they are the right contractor for your particular house.
What we can do is give you a much better place to start.
Because if I am spending this much money on the outside of my house, I want more than a pretty website and a yard sign.
I want to know who I am hiring, what they are actually proposing and why it makes sense for my house.
The Guide: Siding and Window Contractors Near Frenchtown, NJ
Siding and window work in New Jersey is registered, not licensed. Every company that re-sides a house or replaces its windows for a homeowner is required to hold a Home Improvement Contractor registration — the number that begins 13VH — and the state records that registration to a legal entity and a town, both of which are frequently not the ones on the company’s website. The registration is free to check and takes ninety seconds. This guide does it for six companies.
Two things distinguish this trade from roofing, and both are on this page. The first is that siding tear-off and window replacement on any house built before 1978 fall under a federal lead-paint rule with its own certification, which almost nobody publishes — and Flemington’s historic district and the older streets of Clinton and High Bridge are exactly where that rule bites. The second is that Frenchtown has its own siding trade: one company in this guide keeps premises, or is recorded by the state, inside the towns it covers.
How We Selected These Companies
This guide covers six places: Frenchtown, Milford, Holland Township, Kingwood Township, Bethlehem Township and Union Township.
A company appears here if it installs or replaces residential siding or windows for homeowners in those towns, publishes that work as a named service on its own website, and holds a New Jersey Home Improvement Contractor registration that the state records as active. For a company based outside the six towns, its own website has to name one of them, or Hunterdon County, as somewhere it works, or its premises have to sit in Hunterdon County within a few miles of them. That is the whole test. It is not a test of size, of price, of how long a company has been trading, or of what we think of its work. One company meets it and are listed alphabetically. A company that does roofing only is on our roofing guide for these towns instead.
What a company publishes about itself is not the criterion. It is the content. Where a business publishes a registration number, this guide prints it and reports what the state record says about it. Where a business publishes nothing, this guide says so plainly and dates the statement. Neither is a compliment or a complaint.
About This Guide
This guide is produced by Garden State Circle. Companies appear here because they meet the criteria described above — they install or replace residential siding or windows for homeowners in the towns this guide covers, publish it as a service, and hold an active state registration. That is a test, not a judgment, and it is the only route onto this page. No company can pay to be included in this guide, to be listed higher, or to change what the comparison table says about it. Companies are listed alphabetically, and every detail in the table was verified against each company’s own website and against the New Jersey Division of Consumer Affairs registrant record in September 2026.
Everything under the heading that begins this guide is governed by the rules above, on every guide we publish. Where a sponsor’s message appears above that heading, it is paid for and labelled, and it buys nothing in the guide. Garden State Circle is supported by the businesses that participate in it. Participation pays for our ongoing work: keeping a business’s entry accurate, re-checking its record, and publishing a page of its own details that the business maintains. There is no paid placement in this guide. Participation does not buy a place here, a position here, or anything the comparison table says.
Garden State Circle is published in New Jersey by Tiffany and Jake Slowinski and covers Frenchtown, Milford, Holland Township, Kingwood Township, Bethlehem Township and Union Township.

Which of These Companies Is Actually in Frenchtown
Flemington has Fox Chase Contracting on Minneakoning Road. Lebanon has Hunterdon Roofing, Siding & Window Company on Route 31 and Home Exteriors Direct on Main Street. Deegan Brothers lists an Old Highway 22 office in Clinton among four addresses, and Euro Roofing & Siding is in Ringoes, in the same county.
The state registers two of the companies in this guide somewhere other than the town they publish. None of that is a mark against anybody. It is why the table carries both towns.

Checked against the New Jersey Division of Consumer Affairs Home Improvement Contractor registration search.
Registrations, registered entity names, statuses and towns were verified against the New Jersey Division of Consumer Affairs registrant record, and services and credentials against each company’s own website and the manufacturer directories named in the entries, in September 2026.
A Note on Reading the Registration Column
Three of the six companies in the table publish a New Jersey registration number on their own website, and one publishes a number that is a digit short. That is the first thing the table shows, and on its own it is only mildly interesting. The second thing it shows is the reason the column is split in two.
The registered name is often not the trading name. Fox Chase Contracting’s registration is held by Fox Chase Maintenance Co LLC. Deegan Brothers is registered as Q & A Corp., with the trade names appended. Euro Roofing & Siding is Euro Construction Group LLC. Every one of those is lawful, ordinary and invisible to a homeowner typing a company name into the state’s search box.
The registered town is not always the published town. Deegan Brothers publishes a Clinton office and is registered in Phillipsburg. Euro Roofing & Siding publishes Ringoes and is registered in Lawrenceville. A registered office and an operating office are different things and a company is entitled to both.
Two companies publish a number a homeowner cannot check. Hunterdon Roofing, Siding & Window Company displays a Pennsylvania registration, PA161132, and not its New Jersey one, 13VH00209500. Euro Roofing & Siding prints 13VH1119300, a digit short of its actual registration, 13VH11193000.
How to check a registration yourself
Search the New Jersey Division of Consumer Affairs licensee verification for Home Improvement Contractors, using the business search rather than the individual one. You can search by the 13VH number if you have it, or by the beginning of the registered name — the name search matches from the start of the name, so a partial word at the front works and a word from the middle does not. The result gives the registered entity, the number, the status and the town. It is free.
What the registration is, and what it is not
A 13VH registration means the business has registered with the state, carries commercial general liability insurance of at least $500,000 per occurrence, and is subject to the Contractors’ Registration Act. It is not a competency examination and it is not a trade license — New Jersey does not test siding and window installers the way it tests electricians, plumbers or heating contractors. It tells you a business exists on the record and can be found again. That is worth having and it is not the same as skill.
The One Certification Almost Nobody in This Guide Publishes
The federal Lead Renovation, Repair and Painting rule applies to any house built before 1978. Siding tear-off and window replacement both trigger it by definition, because both disturb painted surfaces on the outside of the house. A firm doing that work on a pre-1978 house is required to hold its own EPA Lead-Safe firm certification, with a firm number, separate from anything the state issues. Flemington’s historic district, the older streets of Clinton and High Bridge, and much of the housing along Route 22 and Route 31 predate 1978, and the year built for any address is on the municipal tax record.
The companies in this guide publish nothing either way, which is not a finding about whether they hold it — EPA no longer runs a public directory a homeowner can check, so we could not check it for them, and we do not print a column we cannot fill honestly. What a homeowner can do is ask for the number rather than a reassurance, and check the house’s year built on the municipal tax record before signing. We have asked every company on this page for its number, and the answers will be published here as they arrive.
The Companies
Deegan Brothers Roofing & Siding, Clinton
Deegan Brothers Roofing & Siding publishes siding installation and repair and windows and doors alongside its roofing and gutters, from four addresses including Old Highway 22 in Clinton, and names Clinton, Flemington, Annandale, Lebanon, High Bridge, Whitehouse Station and Readington on its contact page.

Fox Chase Contracting, Flemington
Fox Chase Contracting publishes siding alongside roofing, decks and gutter protection from a Minneakoning Road suite in Flemington — windows are not among its services — and names Flemington, Raritan Township and Hunterdon County on its own site.

The number it publishes, PA161132, is a Pennsylvania registration; its New Jersey registration is held by HUNTERDON SIDING & WINDOW COMPANY LLC., active in Lebanon under 13VH00209500, and does not appear on its site.
The Question This Table Cannot Answer Yet
Almost every company here publishes both siding and windows, and most publish roofing, decks or masonry beside them. What no website says is which of those the company does with its own crew and which it subcontracts, and it is the single fact most likely to decide how the job goes. We are asking it, company by company, together with the Lead-Safe question above, and the answers will be published in this table as they arrive. If you have had siding or windows done in these towns by a company on this page, write to admin@gardenstatecircle.com and tell us who actually turned up.
Common Questions
Does a siding or window installer in Frenchtown, NJ need a license?
Not a trade license. New Jersey requires registration as a Home Improvement Contractor — the 13VH number — with commercial general liability insurance of at least $500,000 per occurrence and a written contract for any job over $500. The Contractors’ Registration Act names siding and windows squarely. Every company in the table holds an active registration, and the table says which of them publish it.
Is my house old enough for the lead rule to apply?
If it was built before 1978, yes, and in Flemington’s historic district and the older parts of Clinton and High Bridge that describes most houses. The year built is on the tax record for every property. The rule covers siding removal and window replacement on such a house regardless of whether lead paint has ever been found there, because the work disturbs painted surfaces by definition. The contractor, not the homeowner, is the one who must hold the certification.
What should a siding contract actually say?
New Jersey requires a written contract for any home improvement job over $500, and it must carry the contractor’s registration number. Beyond that, the useful items are the manufacturer and product line by name, whether house wrap and flashing are included, who removes and disposes of the old siding, whether rotted sheathing found underneath is priced or excluded, and who holds the workmanship warranty if the company changes hands.
Why does the registered name not match the company name?
Because registration attaches to a legal entity and trading names are free to differ from it. Several companies in this guide are registered under a name that is not the one on their website — a holding company, a personal-names LLC, a franchisee entity. It is normal, and it is why searching the state registry by the name on your estimate often returns nothing.
What does a manufacturer certification actually get me?
Access to the manufacturer’s longer warranties, which are only available through installers it has certified, and some evidence of installation training. James Hardie, Andersen and ProVia each run installer programmes with tiers. Several companies here name a tier on their own site; we have not checked those claims at the manufacturers, so this guide does not compare them in a column. Ask the installer for the manufacturer’s own listing.
Who Governs Siding and Window Work in Frenchtown, NJ
Siding and window work in New Jersey answers to two state agencies with confusingly similar names, and they do different things. The registration — the 13VH number in the table above — is issued by the Division of Consumer Affairs, Regulated Business Section — (973) 504-6370 — which is where the registration check described above is run. The permit belongs to the Uniform Construction Code, N.J.A.C. 5:23, written by the Department of Community Affairs, Division of Codes and Standards — (609) 292-7899 — and enforced by each municipality’s own construction office. New Jersey adopted the 2024 editions of its construction subcodes on August 17, 2026; the one- and two-family dwelling subcode is the International Residential Code 2024, New Jersey edition (N.J.A.C. 5:23-3.21), and the energy subcode is the International Energy Conservation Code 2024 (N.J.A.C. 5:23-3.18), per the Division’s current-codes table, read September 2, 2026.
This guide covers Frenchtown, Milford, Holland Township, Kingwood Township, Bethlehem Township and Union Township, and each is its own municipality with its own construction office. We have not yet opened those offices and do not list them here; the state search above works in every one of them, and the permit office is found on each town’s own website.
Fee schedules are adopted by ordinance and change. Whether a particular job needs a permit is interpreted by the town’s own construction office, not by us. We publish what each municipality published, with the date we checked it — confirm with the office before you rely on it, and if any of it has changed, the correction address at the foot of this page is the fastest way to tell us.

Something out of date?
This guide is maintained. If anything here is wrong or has changed — a name, an address, a registration number, a certification, or whether a business has closed — tell us and we will check it. Businesses listed here are welcome to write in directly, and a company that publishes a registration number we have recorded as absent is exactly the kind of correction we want.
And if you run a siding or window company that should be on this list and is not, write to us. We would rather be told than be incomplete. The test is the same one every company here cleared: that you install or replace residential siding or windows for homeowners in Frenchtown, Milford, Holland Township, Kingwood Township, Bethlehem Township or Union Township, and that you publish that work as a service on your own website. A permit pulled in one of those municipalities, a completed job, or your registration will do it. Show us that and you go on the page.
