Every estimate starts at your house, not over the phone. We look at the door, the frame, the threshold, and the trim, and take photos of anything that needs attention.

Exterior Door Work in Union, NJ

Replacement, installation, and honest advice on what your door needs.

Entry Door Replacement

The difference between a door that lasts and one that leaks is mostly under the threshold. We install every entry door on a sill pan with flashing, then seal and insulate the frame. You get the door’s manufacturer warranty plus our written workmanship warranty.

Written, Itemized Quote

Once you’ve picked a door, we write it all up. You’ll see exactly what’s included and what each part costs, so you can decide with the whole picture in front of you.

Install, Cleanup & Walkthrough

Once the door is set and sealed, we walk through it together. Open it, close it, lock it. You get the manufacturer’s warranty on the door and our written workmanship warranty on the install.

What You Get When You Hire Nail Force

Everything you should expect from a door installer.

New Lockset Installed

Every door gets its hardware and lockset installed and tested. We check the latch and the deadbolt before we call it finished.

Patio Doors Done Right

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.

Top Door Brands

Doors from Therma-Tru, ProVia, Masonite, and Jeld-Wen give you real choices in style, material, glass, and hardware finish.

Honest Repair Advice

If your door just needs new weatherstrip or a hinge adjustment, we’ll tell you. We don’t sell new doors to people who don’t need them.

Free Estimates

The in-home estimate costs nothing and comes with no obligation. We measure, inspect, and give you an honest opinion and a written price.

Honest Material Advice

Fiberglass or steel, slider or French door, we give you the honest pros and cons and let you choose what fits your house.

Finding the Right Door Company in Union, NJ

Most door problems come from the install, not the door. So when you’re comparing door companies, focus on how they put it in. Do they check the opening and deal with any rot, or just cover it up? Do they flash the opening and use a sill pan? Do they cap the exterior trim so no bare wood is exposed? A good installer will explain all of this without you having to pull it out of them.

Those are the questions we answer at every estimate in Union, without being asked. Sill pan and flashing on every door, low-expansion foam, capped trim, and a written, transferable workmanship warranty. If that sounds like the kind of door company you want, call Nail Force at (973) 713-1053.

What Union Homeowners Ask About New Doors

The questions we get at almost every estimate.

Is door replacement expensive in Union?∨

Honestly, it ranges a lot, which is why we don’t quote over the phone. Size, material, glass, brand, hardware finish, and the shape of your frame and sill all play a part. Financing is available for qualified homeowners if you need it. For a ballpark, use our door calculator, then book a free in-home estimate.

Can someone come to my Union home and measure for a new door?∨

No charge and no strings. Set up a visit, and we’ll inspect the door and the opening, photograph any damage, and explain what we’d recommend. You get an itemized written quote to keep. If the door only needs an adjustment, we’ll tell you that too. Call Nail Force at (973) 713-1053.

Should I repair or replace my front door?∨

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.

Fiberglass vs steel door: which should I pick?∨

For most homes, a fiberglass entry door is the better all-around pick because it resists dents, doesn’t rot the way wood does, and can be made to look like real wood. Steel is a solid, strong choice too, especially for side and back doors. We install both and will help you pick at your free estimate.

What door brands do you install in Union?∨

We install ProVia (including Signet and Embarq), Therma-Tru (including Fiber-Classic), Masonite, and Jeld-Wen doors. We can also install a door you’ve already purchased. Doors we supply come with the manufacturer’s warranty plus our written workmanship warranty on the installation.

Do you offer financing for a new door?∨

You can. Nail Force works with a financing partner to offer financing for qualified homeowners on door replacement and installation. The details depend on your application, so the best next step is our financing page or a quick call to (973) 713-1053.

What warranty comes with a new door?∨

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.

Can I supply my own patio door for you to install?∨

Absolutely. Bring us the door and we’ll handle the install the same careful way we do every job: plumb, level, and square, flashed and sealed, trim capped. The door’s product warranty stays between you and the manufacturer. Haven’t bought it yet? We can measure first. Call (973) 713-1053.

Who does the best patio door installation near Union?∨

Skip anyone who quotes a door over the phone. The best door installers near you inspect the opening, check for rot, and hand you an itemized price in writing. That’s how every Nail Force estimate works. Add our five-star Google reviews and a written workmanship warranty, and we’re worth a call at (973) 713-1053.

Should I replace all my exterior doors at the same time?∨

Not necessarily. Many homeowners start with the front door and replace the others later. Doing several at once can make sense if they’re all worn out, and financing for qualified homeowners can help. We’ll look at every door and tell you honestly which ones need replacing now.
