Clear Remodeling Process: Our 5-Step Coordination Plan

Remodeling has moving parts. We define scope, document assumptions, and coordinate each phase so you know what is happening from consultation through final walkthrough.

Request an estimate
1

Look at the Openings, Not Just the Windows

Measure and AssessWe measure the existing window and frame, check the accessible sill, trim and surrounding wall, and identify whether an insert or full-frame replacement is suitable.
Same Size or ChangingWe confirm whether each opening stays the same or changes, since that affects framing, header and permit questions.
2

Confirm Units, Material and Lead Time

Type and MaterialVinyl, fiberglass, wood or aluminum, the glass package and the operation style are confirmed against the room and budget.
Window ScheduleSizes, quantities and lead time are locked, whether the windows are owner-supplied or ordered through our suppliers, so the wall is not opened early.
3

Remove the Old Unit and Check the Opening

Insert or Full-Frame RemovalFor an insert, we retain a sound existing frame. For full-frame replacement, trim or siding is cut back where needed and the old unit is removed to the rough opening.
Check the ConditionAreas exposed by removal are checked for water damage or rot. Any repairs are documented and priced before the affected area is covered.
4

Set, Flash and Seal

Sill Pan and FlashingFor full-frame work, we prepare the sill and integrate flashing with the water-resistive barrier. Insert units are fitted to the retained frame. Both follow the selected window's installation instructions.
Insulate and Air-SealLow-expansion foam and sealant close the gap around the frame without bowing the unit.
5

Finish the Areas Disturbed by Installation

Trim and SidingWe repair or replace the trim, siding, drywall and paint disturbed by the agreed installation. Insert and full-frame work may need different amounts of finish repair.
Test and Walk ThroughOperation, locks and seals are checked, and any door, skylight or remodel coordination is closed out together.

Frequently Asked Questions

Answers about scope, estimates, scheduling, and project coordination

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.

    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!

What Actually Changes a Window Quote

Window Installation project photo

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.

Window Replacement Cost in Seattle

Window replacement cost in Seattle does not come down to a single per-window number. The unit, insert or full-frame approach, opening condition, glass package, exterior trim, siding, interior finish work, rot repair, access and lead time all affect the scope.

A same-size insert in a sound frame is the simple end. Once the opening changes, siding must be reworked or water damage appears, the job becomes carpentry and water-control work. General Seattle planning figures are often around $1,000 to $3,500 per installed opening, with full-frame, larger and specialty units above that. Treat this as a market range, not a Renova quote.

The window price and the installation scope should be separated. We provide a project number after seeing the opening, surrounding finishes and any proposed size or use changes.

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.
