Skylight Replacement in Issaquah, Bellevue & Sammamish

A skylight is the only opening that brings light into a room with no wall to give it. In a Pacific Northwest winter that is worth more than it sounds — a north-facing room with a skylight reads as bright on a day when every window in the house is grey.

It is also the opening most likely to leak, because it is the one lying flat under the weather.

When a skylight needs replacing

  • Water around the opening. Nine times out of ten it is the flashing rather than the glass — but either way it does not fix itself.
  • Fogging between the panes. The seal has failed. It cannot be cleaned and it will not clear.
  • Condensation dripping in winter. Often a sign the unit is single-glazed or the surrounding shaft is not insulated.
  • Cracked, yellowed or hazy acrylic. Older domed units go brittle and cloudy. Glass units do not.
  • It no longer opens, or will not close fully. Common on venting units where the operator has seized.

Skylights have a shorter life than windows — they take direct sun, standing water and thermal movement all day. If yours is original to a house built before the 2000s, it is due.

The units we install

Fixed skylights

Glass only, no opening mechanism. The most reliable option because there are fewer things to fail, and the best sealed of the three.

Venting skylights

They open, either manually with a pole or on a motor. Worth it in a kitchen or bathroom where you want the moisture out, not just the light in.

Sun tunnels

A reflective tube that brings daylight down through the roof into a room with no roofline of its own — a hallway, a landing, an interior bathroom. Far less disruptive to install than a full skylight and it does not need a shaft framed out.

Replacement is mostly a flashing job

The single most important part of a skylight replacement is not the unit. It is the flashing kit and how it integrates with the roofing around it. A good unit flashed badly will leak; the reverse is rare.

So we replace the flashing every time, matched to your roof covering, rather than reusing what is there. If your roof is close to the end of its life, it is worth doing both together — opening the same area twice costs more than doing it once.

Skylights and skywalls

A skylight sits in the roof plane. A skywall is a different thing entirely — a glazed wall or enclosure that brings light in from the side and the top at once. If you are not sure which you have or which you want, we will look at it and tell you.

What it costs

Price moves with the number of units, the roof covering, whether the opening is being enlarged, and whether the interior shaft needs finishing. Replacing like-for-like on an accessible roof is a straightforward job; cutting a new opening is a bigger one.

Frequently asked questions

My skylight leaks. Do I need a new one?

Usually the flashing has failed rather than the unit. But on a skylight old enough to be leaking, the sealed glass unit is generally near the end too — which is why replacing both at once is normally the better value.

How long does it take?

A like-for-like replacement is typically a one-day job. Cutting a new opening and finishing the shaft takes longer.

Will it make the room too hot?

Modern glass packages handle that. Low-E coatings and the right orientation mean a skylight today behaves nothing like a 1990s acrylic dome.

Can you put a skylight in a room with no roofline?

That is what a sun tunnel is for — it carries daylight down a reflective tube from the roof to a room below.
