What We Do for Doors in Knowlton
Front doors, patio doors, storm doors, side doors. One call covers it.
New Front Door Installation
Single entry doors, doors with sidelites, full entry systems with a transom. We take out the old unit, square up the opening, and install the new one so it latches clean and seals tight. The old door and all the debris get hauled away when we’re done.

A patio door can slide or swing. An entry door can be fiberglass or steel, plain or with glass, alone or flanked by sidelites. We explain what each option means for looks, upkeep, and your budget, then help you land on the right one.

How Door Replacement Works with Us
Four steps. No pressure, no surprises on the bill.
Call or Book Online
Pick up the phone or book online. Tell us if it’s a front door, patio door, storm door, or one you already bought. We’ll schedule your free in-home visit.
Free In-Home Estimate
During the visit we figure out why the door is sticking, drafting, or leaking. You’ll see photos of the problem areas and get our honest take on replacing versus repairing.
Your Price in Writing
Next comes a written quote with every line item listed. Door model, glass, hardware, installation, trim, haul-away, and how any framing repair is handled. No lump sums and no fine-print surprises.
Install, Cleanup & Walkthrough
After the door is in, we test the swing, latch, and weatherstrip in front of you. The work area gets cleaned, the old door leaves with us, and your written workmanship warranty is in hand.
Why Choose Nail Force for Door Replacement?
Here’s why homeowners pick us over the next guy.
You get the manufacturer’s warranty on the door plus our written workmanship warranty on the installation. It transfers to the next owner if you sell.
Already bought a door? We’ll install it for labor only. The product warranty stays between you and the manufacturer, and the install gets the same care.
Sliding and French patio doors go in level, flashed, and sealed, so the panels roll or swing smoothly and water stays outside where it belongs.
Exterior trim around the new door gets capped, so there’s no bare wood left out in the weather to soak up water and rot.
Financing is available for qualified homeowners through our financing partner, so a door that can’t wait doesn’t have to wait on your budget.
Front entry, back door, patio slider, French doors, storm door, garage side door. One company handles every door on your house.
How to Tell a Good Door Installer from a Bad One
Ask every door company the same three questions and compare the answers. First, how do you keep water out at the sill? You want to hear sill pan and flashing. Second, what do you insulate the gap with? The answer should be low-expansion foam, not the kind that expands hard and bows the frame. Third, what’s in writing for the warranty, on the door and on the labor? Vague answers on any of these are a red flag.
No vague answers here. Ask us how we handle rot and we’ll show you. Ask about the warranty and we’ll give you the terms in writing. Ask about our reviews and we’ll point you to Google. Homeowners in Knowlton can schedule a free door estimate at (973) 713-1053.
Your Door Questions, Answered
The questions we get at almost every estimate.
It depends on the door you choose, the material, the glass, whether you want sidelites or a transom, and the condition of the frame and sill underneath. Anyone who prices a door without seeing the opening is guessing. We’ll measure and inspect for free and give you a written, itemized price. For a ballpark first, try our door replacement calculator.
Your new door is protected by the product warranty from the door maker plus a written, transferable workmanship warranty from Nail Force. We don’t do handshake warranties. Everything is on paper, so you know what’s covered on the door and on the installation, and so does the next owner.
Our answer depends on what we find, and we’ll never push a new door you don’t need. Worn seals, loose hinges, and a misaligned latch are usually fixable. Warped panels, cracked or fogged glass, rust, and rotted sills or jambs usually aren’t worth patching. We’ll give you photos and an honest recommendation.
Compare door installers on credentials, reviews, and how they quote, and you’ll find Nail Force Contracting near the top. We’re licensed and insured, five-star rated on Google, and every job gets a free in-home estimate and a written, itemized quote. We install Therma-Tru, ProVia, Masonite, and Jeld-Wen doors. Call (973) 713-1053.
Absolutely, and there’s no obligation. A real estimate needs a real measurement, so we come to your house, check the rough opening for plumb and square, and look at the sill and jambs. You’ll leave with photos of anything we find and a written quote.
Usually, yes. A new door with fresh weatherstrip, installed and sealed properly, can make a real difference. The install is a big part of it. We insulate the gap around the frame with low-expansion foam and seal it, then check the weatherstrip and the swing before we leave.
It comes down to light versus privacy. Glass in the door or sidelites brightens a dark entry, and privacy glass lets light in without letting people see in clearly. Solid doors give the most privacy. We’ll bring glass samples to your estimate so you can see the options in person.
Fiberglass wins for a lot of front doors, since it holds up well to weather and can be stained or painted. Steel makes sense when you want a solid, sturdy door at the side or back of the house. Either way, the install matters more than the material. Call (973) 713-1053 and we’ll walk you through the options.
Yes, qualified homeowners can finance their door project through our financing partner. That can cover a single front door or every exterior door on the house. Ask about it when we come out for your free estimate, or visit our financing page to learn more. Call (973) 713-1053 with questions.
Yes, labor-only installs are something we do regularly. You provide the door, and we check it against your opening, look for rot, and install it with a sill pan, flashing, low-expansion foam, and capped trim. The product warranty is between you and the manufacturer. Your quote for the install comes itemized in writing.
