Patio Doors in Normandy Park
A patio door should open with one hand and keep the rain on the deck where it belongs. We replace worn sliders and French doors with new ones that fit right and seal tight, and one person stays with your job from the first call to the final sweep.

New patio doors, set on a dry and solid base
Patio doors take more abuse than any window in your home. They get opened dozens of times a day, the sill sits right where rain runs off the deck, and the glass panels are heavy. When rollers wear out or the sill starts letting water in, the door gets hard to use and the floor under it can quietly rot.
We install sliding patio doors and hinged French doors in vinyl, fiberglass and wood-clad frames. The real difference is underneath: we check the subfloor at the threshold, fix what we find, and set the new door on a sloped sill pan so any water that gets past the weatherstrip drains back outside.
You deal with one person the whole way. The same contact who measures your opening orders the door, schedules the crew, answers your questions on install day and walks the finished door with you.

What a patio door replacement includes
- 01
Measuring and a look underneath
Sizing is taken from the framed opening in the wall rather than from the door that is there now. We also press-test the sill and nearby floor for soft spots and share photos of anything we find before you decide.
- 02
Help choosing the door
We go over sliders and French doors, frame materials and glass choices with you. All of our patio doors use tempered safety glass, and low-E coatings keep a sunny room from overheating.
- 03
Careful removal
Panels come out first, then the old frame. Floor coverings go down inside and the work zone stays contained, so dust stays out of the rest of your home.
- 04
Sill pan and flashing
Before the new frame goes in, we set a sloped sill pan and tie flashing into the existing weather barrier. That pairing is what keeps winter rain off your floor.
- 05
Setting, sealing and trim
We shim the frame plumb and square, fill gaps with low-expansion foam, then seal and trim both sides. Rollers, hinges and the lock get fine-tuned until the door closes evenly.
- 06
Cleanup and haul-away
The old door leaves with us and the area is swept before we go. Our installation work carries a 10-year workmanship warranty.
Questions about Patio Doors?
Call(206) 222-6377When a patio door has reached the end of its life
Grinding or slipping off the rail
Tired rollers and a pitted aluminum track make a slider stick and scrape. New rollers are sometimes all it takes, and we will tell you when that is the case.
Fog between the panes
A haze inside the glass that no cleaning removes means the insulated unit's seal has failed. Most of its insulating value is gone.
Water at the threshold
Damp carpet, swollen laminate or a dark mark near the sill after rain usually traces back to failed sill or flashing. Better to catch it before the subfloor goes soft.
Drafts you can feel
Cold air along the edges, or a line of daylight past the weatherstrip, tells you the door no longer seals against its frame.
A lock that will not catch
If the panel has sagged or the frame has moved, the latch no longer meets its keeper. That is a security issue as much as a comfort one.
How your patio door project runs
- 1
A no-pressure consultation
Everything begins with a phone call. You tell us what bugs you about the current door, and we pick a time to come see it.
- 2
Measure, inspect and quote
Your contact measures the opening, checks around the sill and hands you a written, line-item quote. If your project needs a permit, we take care of pulling it.
- 3
Ordering and scheduling
Patio doors are built to size, so the order goes in after you approve the quote. The same person sets your install date and lets you know how that morning will go.
- 4
Install day
Most installs are finished in a single day. The crew takes out the old door, repairs any soft spots below, sets the new door on its sill pan, then seals and trims it.
- 5
Final check together
Before the crew packs up, you try the door yourself, sliding or swinging it and testing the lock. We point out simple care for the track and hinges and answer whatever is left on your mind.
What moves the price of a patio door
Your quote comes written out item by item, so nothing is hidden in a single lump sum. Most of the difference between two projects comes from the door itself and from what turns up once the old frame is out. If the floor or framing under the sill needs repair, you get photos and a plain explanation before any extra work starts.
- Style and width
- A basic two-panel slider tends to come in lower than a set of hinged French doors. Larger openings, and units with three or four panels, raise the total.
- What the frame is made of
- Vinyl frames keep the cost down. Fiberglass and wood-clad frames ask more up front, stand up well to sun and damp weather, and can take paint or stain.
- Glass and hardware choices
- Better low-E coatings, blinds sealed between the panes, decorative grids and multi-point locks all add to the price in their own way.
- The state of the opening
- Soft subfloor or rotted framing at the sill means more labor and material. Resizing the opening, for example going from a slider to French doors, adds work as well.
Patio door questions we hear often
Can I switch from a sliding door to French doors?
In most homes, yes. French doors need room to swing, so we look at where your furniture sits and whether the opening needs small framing changes. If a slider would actually suit the room better, we will say so during the visit.
Is my old slider worth fixing instead?
Sometimes it is. When the frame is solid and the glass is clear, new rollers and a cleaned track often get it gliding again. When the glass seals have failed or water is getting in at the sill, a new door is usually the better use of your money, and we will explain why.
Will there be a gaping hole in my wall overnight?
No. We leave your existing door in place until the new one has arrived and is ready to go in. Most installs are finished in a single day, so by evening the opening is closed up with a sealed door that locks.
Who is responsible if something goes wrong during the install?
We are. We are licensed, insured and bonded, which protects you while the crew is working at your home. If anything about our workmanship needs attention later, you call the same contact who ran your job.
Do you offer ways to spread out the cost?
Yes, we offer flexible payment options. Mention it during your consultation and we will go over what works for your project.
