Entry Door Replacement

What Happens When You Call Nail Force
Straightforward from the phone call to the cleanup.
Tell Us About Your Door
Start with a quick call. Front door, slider, storm door, side door, or several at once, let us know what you have in mind and we’ll set up your free visit.
We Measure and Inspect
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
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.
Installed Right, Cleaned Up
We install the door with a sill pan, flashing, foam, and sealant, cap the trim, and put on the lockset. Then we clean up, haul the old door away, and walk the finished job with you.
What You Get When You Hire Nail Force
No fluff. Just the reasons people hire us.
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.
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.
Front entry, back door, patio slider, French doors, storm door, garage side door. One company handles every door on your house.
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.
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.
We protect the area, clean up as we go, and haul the old door and all debris away. You won’t be left with a pile in the driveway.
What to Ask Before You Hire a Door Installer
Patio doors deserve extra scrutiny. They’re wide, they’re heavy, and the sill takes a lot of water, so a sloppy install can turn into rot in the subfloor. When you get quotes for a sliding or French door, ask how the installer flashes the opening, whether a sill pan is included, and how they make sure the door is level so the panels roll or swing right. If they can’t explain it clearly, keep looking.
Read our Google reviews, then meet us in person and see if we match them. We’re five-star rated, licensed and insured under NJ HIC #13VH14050100, and every quote we write is itemized. Getting door prices in Harmony? Include ours. Call (973) 713-1053 for a free estimate.
Your Door Questions, Answered
Still wondering about something? Call (973) 713-1053.
The best way to know is a free, written, itemized estimate from us. Price depends on the door type and brand, glass and hardware options, and any repairs the opening needs, and we can’t see those from a phone call. Get a rough range from our door replacement calculator, then call (973) 713-1053 so we can measure.
Written coverage on both the door and the install, and it transfers if you sell. That’s what comes with a Nail Force door replacement. The manufacturer handles product coverage, we handle workmanship, and if something about the installation ever seems off, call (973) 713-1053 and we’ll come take a look.
Hire a door installer that’s licensed and insured, measures in person, shows you any rot, and puts both the price and the workmanship warranty in writing. That’s the standard Nail Force works to. We hold NJ HIC #13VH14050100, we’re five-star rated on Google, and our estimates in Harmony are free. Call (973) 713-1053.
That works fine with us. Buy the door you want, then call (973) 713-1053 and we’ll come measure, check the framing, and quote the installation in writing. We install owner-supplied doors with the same steps we use on doors we supply. The manufacturer covers the door itself directly with you.
It comes down to whether the problem is in the adjustment or in the door and frame themselves. Sagging hinges, a misaligned strike, or tired weatherstrip can often be fixed. Rot, warping, rust-through, or a sill that lets water in usually means it’s time for a new door. We’ll show you which with photos.
Yes. Older openings are often out of square or have settled, and that’s exactly why we check every opening before the door goes in. We shim and fasten the new frame to spec so the door hangs straight, and we show you any framing damage before we fix it.
Most drafty doors have worn or flattened weatherstrip, a door that’s no longer sitting square in its frame, or gaps around the frame that were never sealed. Sometimes an adjustment fixes it. Sometimes the door or frame is too far gone. We’ll check it for free and tell you which.
There’s no single best door for every house, but most homeowners who want a long-lasting front door end up with fiberglass. Steel is a good fit for garage entry doors and back doors. Glass, sidelites, and hardware matter too. We’ll bring samples to your free in-home estimate and give you our honest opinion.
Yes. We’ll come out, measure the opening, check the frame and sill for rot, take photos, and go over door options with you at no cost and with no obligation. You’ll get a written, itemized quote you can take your time with. Call (973) 713-1053 to set it up.
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.
