French door installation looks simple from the driveway. Pull the old pair, hang a new one. A hinged pair is fussier. Two panels have to close on each other and hold a tight line against Seattle weather, which is where a lot of installs come up short. Signature installs exterior and patio French doors across the Greater Seattle area, built to fit the opening and keep the wet out.

Why Homeowners Choose French Doors
French doors open wide and pull the outside in. Two hinged panels swing clear of the opening, so you get a full walk-through instead of the half-width a slider leaves you. The glass carries daylight deep into a room, which counts where winter afternoons go gray by four.
Open both panels on a warm evening, and the living room and the patio feel like one space. On a Craftsman or a newer build, a well-made pair reads as an upgrade the moment you walk up.
French Doors or a Slider? How to Decide
Here is the honest version, since we install both.
A slider glides on a track and takes up no floor space. A French door swings, so it needs room to clear a rug, a chair, or the grill on the deck. If your patio is tight, a slider often wins.
French doors win on the look and the full opening. Thrown open, there is no center track parked in your view. You also get a choice a slider cannot. The in-swing or out-swing. An out-swing door sheds a wind-driven downpour better, because the weather presses the panel tighter into its seal.
Still weighing the two? Our sliding patio doors page covers that side, and a free visit sorts out which fits your room.
Professional French Door Installation Done Right
Even a top-tier French door leaks if the install cuts corners, and a hinged pair gives corners more places to hide.
Installing French doors well comes down to a square opening and honest water management. The frame has to sit dead square, or the two panels will not close cleanly and the astragal, the strip where they meet, will not seal. A door even slightly out of square drags at one corner and gaps at the other.
Then the water. We flash the opening, set a sill pan under the threshold, and lap everything so the wet drains back outside instead of tracking into the framing. Caulk is a finish. Skip the flashing and it shows in the first hard winter, because water management is the part of French door installation you never see once the trim goes on.
Materials for Exterior French Doors
We build French doors in two materials that last here, and we are upfront about which fits your house.
Fiberglass. This is what we lead with for most exterior French door installation. Infinity from Marvin holds its shape through our damp, swinging weather, so the two panels keep their fit and the weatherstrip keeps its bite. Rain does not swell it, and it will not rot at the bottom rail where wood doors give out first. If you are staying put, fiberglass usually pays off over the years.
Wood. Wood brings grain and weight a molded door cannot fake. We install Simpson wood French doors, including Douglas Fir that suits a Craftsman or bungalow. It asks for a refinish every few years and some overhead cover, but the look is hard to argue with. Our exterior wood door page lays out that trade-off.
Custom French doors are the norm here. Most older Seattle openings are not stock-sized, so we build to your opening in two, three, or four-panel layouts.
French Patio Doors That Connect Indoor and Outdoor Living
French patio door installation is where these doors earn their keep. A pair off the back of the house turns a plain wall into a doorway to the deck or the garden.
For a wider opening, a multi-panel layout pulls even more of the back wall away. And if the hole you have is too small for the result you want, we can enlarge it. That means a new header and reframing, a line a lot of installers will not cross. It is routine for us. See our Issaquah case study, where we opened a cramped French door into a full three-panel run.
Security and Energy Performance
An exterior French door is often a real point of entry, so security carries real weight here.
Our units run a multi-point locking system that grabs the frame at several points instead of one. It is far harder to force than a single deadbolt, and it draws the two panels snug at the same time.
The glass handles the energy side. Low-E glass with an insulating gas fill slows heat loss in winter and cuts glare in summer. Pair it with a frame that keeps its line and the door stops bleeding warmth at the back wall.
Choosing Signature for a French Door Project
We have been a family-owned French door installer across the Greater Seattle area, Everett down to Tacoma, since 1999. On a hinged door the tolerances are unforgiving, so our crews square the opening before a single panel goes in.
Every French door installation carries our lifetime installation warranty. It holds for as long as the house is yours and covers our labor, the materials, and any service call with no trip charge. Our satisfaction guarantee is a separate promise on top of that, and if a repair would serve you better than a new door, you hear that from us first.
Our French Door Installation Process
Here is how a job runs. It opens with a free in-home visit, where we size the opening and lay out materials against your budget. From there the door is built to your exact opening, set with the flashing and sealing a swing door needs, then closed out with a walkthrough of the finished work and the warranty.
Frequently Asked Questions About French Door Installation
How much does French door installation cost?
French door pricing swings with the material, the glass, the hardware, and whether the opening needs any structural change for a wider door. A custom exterior pair sits well above a basic interior set. We do not quote blind, so the real figure comes from a look at your actual opening.
How long does it take to install French doors?
A clean swap moves fast. Widening the opening or repairing rot behind the old frame stretches it out. Once we have seen the opening in person, we give you a real schedule rather than a phone guess.
Can French doors improve energy efficiency?
Yes, if the glass package and the install both do their part. Low-E glass slows heat loss, and a door that truly seals keeps the draft out. Skip the flashing and even good glass will not save it.
Can French doors replace my existing sliding patio door?
Often, yes. Trading a slider for a French pair is a common project. The opening sometimes needs a tweak for the swing, which we handle.
