Windows and Doors We Install and Repair
Most of our work is window replacement: pulling out old aluminum sliders or failed double-pane units and setting new, energy-efficient windows with proper flashing. We also install entry doors, patio doors and storm doors, and we handle window repair when a new seal, balance or roller fixes the problem for less. For offices and shops, our commercial windows service covers replacement on small business buildings.
Window Replacement
New vinyl or fiberglass windows set as inserts or full-frame, flashed against wet winters and sized to meet the state energy code.
Entry Doors
Prehung fiberglass and steel entry doors installed over a sloped sill pan, shimmed at every hinge, and adjusted until they latch with one hand.
Patio Doors
Sliding and hinged patio doors installed over a sill pan, with rollers, locks and glass chosen to stay smooth and tight through wet winters.
Window Repair
We fix fogged glass, broken balances, stripped cranks and rotted sills so a sound window opens, locks and seals again without replacing the whole unit.
Storm Doors
Aluminum storm doors with glass and screen panels, fitted to out-of-square openings so they latch cleanly and keep wind-driven rain off your entry door.
Commercial Windows
Storefront glass, office windows and failed insulated units replaced to current energy and safety code, scheduled around your business hours.
Why Homeowners Call Us
A window is only as good as the opening it sits in. Here is how we work so the new unit performs the way its label says it will.
- We check the framing before we quote
- Plenty of homes around here still have original single-pane aluminum windows over wood sills that have been wet for decades. We probe those sills and the framing below them during the estimate, so soft wood shows up on the quote and not as a surprise on install day.
- Flashing that drains, not just caulk
- Caulk alone fails within a few seasons. We set a sloped sill pan or flashing tape under each window, lap the layers so water runs out instead of in, and seal the exterior with a sealant matched to the frame material. Low-expansion foam fills the gap between frame and rough opening to stop air leaks.
- An honest repair-or-replace answer
- If a fogged pane can be fixed by swapping the insulated glass unit, or a sticking sash just needs new balances, we tell you. Replacement is the right call when frames are rotted, warped or leaking air at every joint, and we show you why.
- Coverage that outlasts the install
- The windows and doors we put in carry a lifetime warranty. At the quote visit we read the coverage terms through with you, so you know what is included before anything is signed.
- Written quotes with every line shown
- Your estimate lists each opening, the frame and glass you chose, trim and any repair to the rough opening. You see what you are paying for, and nothing gets added without a conversation.

A Window and Door Company Built Around One Area
Shoreline Window Replacement does one thing: windows and doors for homes in Shoreline and the towns around it. We do not sell siding or roofing on the side. That focus means we spend our days on sill pans, sash balances, door thresholds and the details that decide whether an opening stays dry.
We work in houses that have seen decades of Northwest rain, and we know where they tend to fail. Our job is to explain what we find in plain terms, give you a fair price in writing and leave your home cleaner than we found it.

What Sets the Price of Your Project
Two quotes for the same house can land far apart, and usually for real reasons. These are the things that move the number on a window or door job. We walk through each one at your home so the quote makes sense line by line.
Your quote is free and comes in writing once we have measured your home. We offer flexible payment options and lay them out when we review the numbers with you.
- Number and size of openings
- More windows mean more material and labor, but a crew moves faster per opening on a whole-house job than on a single window. Large picture windows and tall patio doors need heavier glass and an extra installer to set them safely.
- Insert or full-frame install
- With an insert, also called a pocket replacement, we pull the old sashes and set the new unit into the existing frame. Your interior casing and exterior trim stay where they are, so labor and material run lower. A full-frame install strips the opening down to the studs. It costs more, but it lets us repair rot and flash the opening from scratch.
- Frame material and glass package
- Vinyl is the most common choice and holds up well in damp weather. Fiberglass costs more, keeps its shape through temperature swings and can be painted. Low-E coatings, argon fill and triple-pane glass each change the U-factor and the price.
- What is under the old window
- Rotted sills, wet sheathing or a sagging header have to be fixed before a new unit goes in. We probe suspect spots during the estimate and price the likely repair, though some damage only shows once the old frame is out.
- Access and permits
- Second-story windows over a deck or a steep slope need ladders or staging. Where a permit is required, the fee and inspection time are part of the job, and we list them on the quote.
How a Job Runs
From the first phone call to the final check, you know what happens next and who is doing it.
- 1
Phone call and visit
You tell us what is going on: drafts, fogged glass, a door that drags. We set a time to come out, look at every opening you want done and talk through frame and glass options.
- 2
Measuring and a written quote
Older framing is seldom square, so we take readings at the top, middle and bottom of every opening, both across and up and down, and size to the smallest one. You get a line-item quote and time to think it over.
- 3
Ordering and permits
Windows and doors are built to those measurements. While they are on order, we handle any permit the job needs.
- 4
Install day
Drop cloths go down first. We take out the old units, repair the openings, then set, flash and seal the new ones inside and out. Most installs are done in one day.
- 5
Final check and haul-away
Before we pack up, you work each sash, lock and door yourself while we watch, and we show you how the tilt-wash latches release. The old units and every scrap of debris leave on our truck.
Questions Homeowners Ask Us

How much do replacement windows cost?
It depends on how many openings you have, the frame material, the glass package and whether the framing underneath is sound. We do not give a number over the phone without seeing the windows. We come out, measure and give you a free written quote with each opening listed.
My window is foggy between the panes. Do I need a new window?
Not always. A haze trapped inside a double-pane window tells you the edge seal around the glass has broken down, letting humid air seep into the space between the two lites. If the frame and sash are still solid, replacing only the sealed glass is often enough, and we handle that as a window repair. If the frame is rotted or the whole window leaks air, replacement makes more sense.
Why do my windows drip with condensation in winter?
Warm, damp indoor air hits cold glass and the moisture condenses. Single-pane glass and older aluminum frames run coldest, so they sweat the most. Low-E double-pane glass with a warm-edge spacer keeps the inner pane warmer and cuts condensation a lot, though indoor humidity and ventilation matter too.
How long does installation take?
Most installs are done in one day. Large whole-house jobs, or openings that need rot repair first, can run longer, and we tell you that up front when we quote.
Do I need a permit to replace windows?
It depends on the city and the scope. A same-size insert replacement is treated differently than enlarging an opening or turning a window into a door. New windows also have to meet the Washington State Energy Code for efficiency. We check the rules for your address and pull any permit the job needs.
Should I choose vinyl or fiberglass frames?
Vinyl is affordable, needs no painting and resists moisture well, which is why most of our window replacement jobs use it. Fiberglass expands and contracts less with temperature, so its seals stay tighter over time, and it can be painted a darker color without warping. We show you samples of both and explain where the extra cost of fiberglass pays off.
Is there a way to pay over time?
There is. We offer flexible payment options, and we set them out next to your written quote so you can see how each one works before you decide.
