About windows for remodels

Two window quotes for the same house can land thousands apart, and it usually has little to do with the brand on the sticker. The variables are the wall, the fit and the schedule.

First, does the new unit match the existing size, or is the opening changing? A like-for-like swap is one job; a resized opening pulls in framing and header work. Second, what is the wall doing with water? The sill, flashing and the water-resistive barrier are what keep the opening dry, so an exterior unit is a water detail, not a glass detail. Third, lead time: custom sizes, colors and glass packages can sit for weeks, so the order has to be placed before the wall is opened.

That is the part of window replacement in Seattle that drives cost and schedule. Window installation rarely happens alone either, so if siding, trim, drywall or paint get disturbed, that repair belongs in the same quote. We would rather price the whole opening honestly than quote a unit and surprise you with the wall.

A Window Is a Water Detail, Not a Glass Order

The glass unit is the easy part. What earns its keep is everything at the edges: the sill, the flashing, the water-resistive barrier and how the siding and trim close back over them. Set a modest window into a clean, flashed opening and it performs. Set a good one into a sloppy opening and you find out the first wet winter.

Where two jobs split

The biggest fork is whether the unit drops into the existing frame or the opening goes back to the studs. The first keeps the wall mostly intact. The second is the call when the old frame, sill or trim should not stay buried behind new glass, and it is usually what moves the price.

Old Seattle openings are rarely square

Older homes move. Headers sag a little, sills tip, and a unit ordered to the listed size will not sit right without shimming and trim work. We measure each opening on its own instead of trusting one number for the whole house.

When the window is really another job

A bedroom window can be an egress question, which ties into basement finishing. A wall full of windows usually overlaps siding work. A roof opening is a skylight and lands on the roofing side. And windows and doors share walls, trim and orders often enough that we plan them together.

The honest version: we price the opening and the water path, not just the unit, so the number still means something in February.

Why homeowners choose Renova Contractors LLC

Clear Scope

Opening Condition First

We check the existing frame, trim, siding and water damage risk before deciding whether an insert or full-frame replacement makes sense.

Better Tie-In

Flashing and Water Control

Window replacement should include the right flashing, sill detail and exterior tie-in so the opening is not treated like a caulk-only repair.

One Plan

Remodel Coordination

We coordinate windows with siding, trim, drywall, paint, basement egress, doors and larger remodeling scopes when they overlap.

No Guessing

Owner-Supplied or Contractor-Supplied

Windows can be selected by the homeowner or supplied through the project, but sizes, lead times, delivery and damage responsibility need to be clear.

    Nik, Oleg, and Russell all did a great job on a tricky window installation in our newly renovated kitchen on Mercer Island. They handled the masonry, millworker, drywall, and interior painting. We came home to a very nicely done and completed room

    Had a basement finishing project on my house in Magnolia. Hired Renova Contractors. Great experience, great craftsmanship, the project was completed on time and schedule. Nick and Mike were really good managers that handled everything perfectly, they helped me pick the right materials for flooring, the right size windows, did everything by electrical and plumbing code. Passed all city inspections. The crew showed up when promised, I had a direct line with them which made communication so much easier. Was not my first time working with a GC and they set the bar high. Great experience on the basement remodeling!

    Renova replaced aging wooden decking with composite for us and rebuilt our glass railing framing. Excellent work, very communicative. Also very accommodating of additional details we asked to add along the way. Highly recommended!

Windows for Remodels

Questions before your project?

A few practical answers before we plan your project.

Ask a question
How much does window replacement cost in Seattle?

There is no single per-window price, because the opening drives most of the cost. A same-size insert on a sound wall is the low end, while full-frame work, changing the opening, siding repair or rot repair moves it up. General Seattle market figures for installed replacement windows are often quoted around $1,000 to $3,500 per opening, with larger or specialty units higher. That is a planning range, not a Renova Contractors LLC quote, and we price after seeing the openings.

What is the difference between insert replacement and full-frame replacement?

An insert sets a new window into the existing frame and is faster when that frame and the surrounding wall are sound. A full-frame replacement removes the unit down to the rough opening so the framing can be checked and the opening flashed properly. The right one depends on the condition of the existing frame.

Do I need a permit to replace windows in Seattle?

A same-size replacement is often simpler, but enlarging an opening, changing structure, adding or changing an egress window, altering the building envelope, or anything touching fire or life-safety conditions can trigger permit or review. Permit needs depend on the actual scope, so we confirm it before ordering or opening the wall. This is general information, not legal advice.

Can Renova Contractors LLC replace windows during a larger remodel?

Yes. Most of our window work happens alongside other scopes, so we coordinate windows with siding, exterior trim, drywall, paint, basement egress, doors and larger remodels when they overlap, instead of treating the window as a separate visit.

Who supplies the windows?

Either the homeowner or the project. Windows can be owner-supplied or ordered through our suppliers, but the sizes, lead time, delivery and who is responsible for a unit that arrives late, wrong or damaged should be clear before the wall is opened.

What happens if the framing or siding is rotten around the window?

It is a possible condition, not a given. If the header, sill, studs or siding turn out to be water-damaged once the old unit and trim come off, we document and price the repair before covering it back up, so it is handled in the open rather than assumed up front.

Are egress windows handled differently?

Yes. A window that serves a bedroom usually has to meet egress sizing, which can mean enlarging the opening, cutting into a concrete or framed wall, and adding a window well and drainage. That is planned with the basement or bedroom scope and the permit path rather than as a simple swap.
