Front Door Replacement & Installation

We replace entry doors of every kind, including doors with sidelites and transoms. You’ll see any damage we find before we fix it. The new unit goes in plumb, level, and square, sealed against air and water, with the exterior trim capped so there’s no bare wood left to rot.

How Door Replacement Works with Us

Here’s exactly how a door job goes with us.

1

Reach Out to Us

Reach out by phone or through our website and describe the door trouble you’re having. We’ll ask a few questions and book a free estimate at a time that suits you.

2

We Measure and Inspect

At your house, we open and close the door, check the latch and weatherstrip, and look closely at the sill and trim. If there’s water damage, we show you before anything else.

3

Written, Itemized Quote

We put it all on paper. The door you picked, the hardware, the sill pan and flashing, the trim capping, and haul-away of the old door. Compare it against anyone’s.

4

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.

Reasons to Pick Us for Your New Front Door

A new door is an investment. Here’s what you get for it.

Your Door, Our Install

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.

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.

Rot Shown First

If we find soft or rotted wood at the sill or frame, we show you before we fix it. No hidden charges, no surprise add-ons.

Top Door Brands

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

Straight Answers

Ask us anything about doors, materials, or the install and you’ll get a plain answer. If we don’t know something, we’ll find out and tell you.

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.

Finding the Right Door Company in Dover, NJ

Be careful with any door quote that doesn’t mention the opening. Replacing a door is really two jobs: the door itself and the frame, sill, and trim around it. If a contractor never brings up rot, flashing, or trim, they either didn’t look or don’t plan to deal with it. Ask directly. How will you handle soft wood? What goes under the new sill? Will the exterior trim be capped? The answers separate careful installers from rushed ones.

Our quotes, our installs, and our reviews are open for you to check. That’s the best way we know to earn the job. When you’re ready for a new front door, back door, or patio door in Dover, call (973) 713-1053 and we’ll set up your free estimate.

What Dover Homeowners Ask About New Doors

Straight answers to what Dover homeowners ask us most.

What does entry door replacement cost in Dover?∨

There’s no honest one-size answer, because every door and every opening is different. A fiberglass entry door with sidelites is a different job than a single steel back door. We come out, measure, check the framing, and hand you an itemized written quote at no charge. You can also get a starting point from our online door calculator.

Do you have payment options for a new patio door in Dover?∨

We do. Financing is offered through our financing partner for homeowners who qualify, and it works for entry doors, patio doors, storm doors, and side doors. You’ll still get a free estimate and an itemized written quote first, so you know what you’re financing. Details are on our financing page.

What kind of entry door do you recommend?∨

Steel and fiberglass are both solid choices, so think about looks, upkeep, and location. Fiberglass handles weather well and can pass for real wood. Steel is tough and no-nonsense, great for utility doors. We’ll give you our honest opinion for each opening on your house and show you samples.

Do you install doors bought from a store in Dover?∨

Of course. Plenty of homeowners order their own door and call us to install it. We’d suggest letting us measure before you order so the size and swing are right. After that, it’s the same careful install we do on every job. The door’s product warranty is between you and its manufacturer.

How do I find a good door company in Dover?∨

Start with credentials and reviews, then judge the estimate. A good installer measures in person, checks for rot, and hands you an itemized written quote. Nail Force is licensed and insured, five-star rated on Google, and backs every installation with a written, transferable workmanship warranty. See why homeowners hire us and call (973) 713-1053.

Does patio door installation in Dover come with a warranty?∨

New doors from us come with two protections in writing: the manufacturer’s warranty on the door and our written workmanship warranty on the installation. The workmanship warranty transfers to the next owner if you sell. If you supplied the door yourself, its product warranty is handled between you and the manufacturer.

Can you install a new door in the winter?∨

Yes, we install exterior doors in every season. We plan the work so the opening isn’t left exposed any longer than needed, protect the inside of your home while we work, and seal the new door properly no matter the weather. Call (973) 713-1053 to schedule a free estimate.

Is your door estimate really free?∨

Sure thing. Getting a free door estimate is as easy as calling (973) 713-1053. We come out to your home in Dover, take real measurements, check the framing for water damage, and give you a written quote that lists every item. There’s no cost and no obligation.

What’s the best front door for security?∨

A solid fiberglass or steel entry door in a sound frame, with a quality deadbolt and lockset, is the strongest setup for most homes. The frame and fastening matter as much as the door. We fasten every frame to spec, install and test the lockset, and show you how everything works.

When is it time to replace an entry door in Dover?∨

Replace it when the door itself or the frame is failing. Warped slabs, rot at the bottom rail or threshold, rusted steel, and drafts that come back after new weatherstrip are all signs. Minor sticking or a loose latch can often be adjusted. We’ll inspect it for free and give you a straight answer, not a sales pitch.
