Window Replacement in Langley, WA

Replacement windows set right for island wind and rain

Window replacement is one of the biggest comfort upgrades an island house can get. We take out windows that are drafty, fogged, stuck or rotted at the sill. New vinyl or fiberglass units go in, flashed and sealed for weather that blows in off the water. Whidbey Roofing and Siding is based in Langley, so there is no ferry wait for a bid.

A window is only as good as the opening it sits in. We line the opening, set a sill pan and tie the flashing into the weather barrier. If we find rot in the sill or the framing, we handle that rot repair first. Then the trim goes back and the wall looks like it always did.

What We Handle

  • Vinyl and fiberglass replacement windows
  • Insert installs that keep your existing frame and outside trim
  • Full frame installs when the sill or frame has rotted
  • New construction windows set with the siding off
  • Sill pans, flashing and sealant tied into the weather barrier
  • Rot cut out and rebuilt at sills, jambs, trim and framing
  • Trim, siding and paint put back to match the wall
  • Old windows and job debris hauled away

When is it time for replacement windows on Whidbey Island?

Old windows show their age in a few plain ways. Fog between the panes means the sealed glass unit has failed, and cleaning will not fix it. A sash that sticks, drops or will not lock is worn out. A draft you can feel a foot away usually starts at the frame.

Island weather finds the weak spots. Rain falls most of the year, and wind drives it sideways at waterfront and bluff homes. Island County design criteria list a basic wind speed of 97 miles per hour, and hills add to that. Salt air is hard on hardware and old wood.

Water usually gets in at the sill and the lower corners. It runs behind the trim and soaks the framing before anything shows inside. Soft wood or a stain under the sill means the repair is bigger than the window. We open the wall and look before we write the estimate.

Window installation: insert, full frame or new construction

The first choice is how the new window goes into the opening. An insert window sets inside the frame you already have, once the old sashes come out. Your siding and outside trim stay put, and the wall stays closed. The tradeoff is a little less glass, because the new frame sits inside the old one.

Full frame replacement takes the old frame out down to the rough opening. That is the right call when the sill or the frame under it has rotted. We line the opening with a waterproof membrane, set a sill pan and lap the flashing onto the wall. Some siding comes off at each opening, and we put it back when the window is in.

New construction windows have a nailing fin around the frame. They go in when the siding is already off, which is why we set them during new siding work. The fin laps over the flashed opening, and the jamb flashing laps over the fin. That ties the window into the weather barrier on the sheathing.

What window contractors should show you in the bid

A good window bid covers the install as much as the window itself. It should name the frame material and say whether the install is insert or full frame. It should also say who repairs rot behind the trim, and who puts the siding and paint back.

Our crew handles the window, the rot repair and the siding that goes back on. Whidbey Roofing and Siding is licensed, bonded and insured in Washington, license CULVEL*828N4. Estimates are free, and we measure every opening before we write one.

Permits depend on where you live. Island County takes building permits through its online Public Portal. Oak Harbor, Coupeville and Langley run permits inside their own city limits. Whether a window swap needs one depends on the scope, so we check with the permit office before work starts.

FAQ

Windows Questions, Answered

Common questions about windows across Whidbey Island, Camano Island and the Skagit side. If yours is not here, call or text and ask.

Call (360) 544-9655

How much does window replacement cost?
Count and size drive most of it. An insert install costs less than a full frame install, and rot at the sill adds work to either one. Whether siding has to come off matters as well. Estimates are free, so call or text (360) 544-9655 and we will come measure.
My windows fog up between the panes. Can that be fixed?
Fog inside the glass means the seal on that unit has failed. Wiping the glass does nothing, because the moisture is sealed in. Usually the window gets replaced, though on some newer units the glass unit alone can be swapped. We will tell you which one you have when we come out.
Should I get vinyl or fiberglass windows?
Vinyl frames are the common pick here. They resist moisture well and never need paint, which suits a wet, salty climate. Fiberglass frames are stiffer and hold their shape as temperatures swing. We can quote both so you see the difference before you choose.
Do you have to take the siding off to replace my windows?
An insert install leaves your siding alone, because the new window sets inside the old frame. A full frame install needs some siding off around each opening so the flashing can lap onto the wall. We cut back only what the opening calls for and put it back to match.
Can you replace just one or two windows?
Yes. One leaking or rotted window is a normal job for us, and so is a whole house. Plenty of people start with the worst wall and do the rest later. If a door is failing too, we handle exterior door replacement in the same project.
Can windows go in during a siding or roofing project?
Yes, and that is often the better order. New windows should be flashed into the wall before the siding goes back on. Doing both at once keeps us from opening the same wall twice. When the roof, siding and windows are all due, we run it as one exterior remodeling project.

They installed a new metal roof on the house we purchased and were able to start quickly which meant it was nearly done by the time we moved in. We had a great experience working with Jeff who was very helpful with suggestions on some cosmetic changes we made and the entire roof and gables came out nicely. Very pleased with this company and would recommend them to anyone on Whidbey looking for roofing or siding work.

Whidbey Roof and Siding did an outstanding job. Very professional! No playing games came in with the lowest bid. We did run into a few surprises, but Jeff was very clear and transparent about what it would take to correct the issue. Very glad I had someone who could deal with the issues. As one recent visitor said the skylight looks like it was here all along and not an after thought addition. Highly recommend
