Permanent Trim & Landscape Lighting in Mercer Island

Permanent Trim Lighting in Mercer Island, WA

Big roof planes are the shape of a Mercer Island house from the street, and most of them sit unlit. Many homes here date to the 1960s through the 1980s, under Douglas firs and madronas that grew up around them. Permanent trim lighting traces the lines you choose and stays there.

Not every edge needs a run. On a First Hill or Mercerwood house with wide planes and skylights, one clean line often does more than lighting everything at once. Sorting that out is what the design walkthrough is for.

This is a one-time install you own, not something that goes up in November and comes down in January. The channel is matched to your trim color, so in daylight it reads as part of the house. Moisture off Lake Washington is the condition the system is built to sit in.

Mercer Island questions

Will it look like holiday lights someone left up all year?
No. In daylight the channel reads as a trim line in your trim color, and at night the default is warm white. Colors only show up when you pick them.
Does it stay with the house?
Yes. It is mounted on the home and it is yours, so there is nothing to take down and nothing to hand back.

Why it matters

The problem this solves.

Seasonal lights mean someone is up a ladder twice a year, and the rest of the year your roofline sits dark. There is usually no safe, good-looking way to add accent or security lighting up high without booking a fresh install every time. The spots that make a house look finished, the eaves, the peaks, the rooflines, are exactly the ones that are hardest and least safe to reach on your own.

How we do it

Our approach.

We install a track of individually addressable, weather-rated LED points along your eaves and rooflines, tucked into a low-profile channel color-matched to your trim, so it disappears in daylight and only the light shows at night. Our crews mount it at roofline height the same way they handle every other job here, trained and insured for it, including tall and steeply pitched roofs. Once it is up you control everything from an app: warm-white everyday lighting, holiday colors, game-day themes, party scenes, and schedules that come on at dusk. It is a one-time install you own, so you are never on a ladder and never booking a seasonal hang again. It pairs naturally with our holiday lighting service, which stays the right choice for wrapping trees, lining walkways, and large statement displays.

A WindowWorks technician training on the mock roof at our facility

  • Background-checked

    Every technician is background-checked before they ever step onto a customer's property.

  • Certified, skill by skill

    Our crews earn certification across 369 individual skills in 10 categories, each one signed off by an evaluator, never just by clocking time.

  • Paid like professionals

    A living wage, healthcare, and dental. People who are treated well do careful work, and they stay, so you see the same faces.

  • Licensed, bonded, and insured

    With OSHA-aligned safety training for the at-height work. If someone is on your roof, they are trained and covered for exactly that.

  • Method matched to the surface

    Soft wash where pressure would damage, hot water where cold cannot lift, the right chemistry for the stain. The method follows the surface, not the other way around.

  • Documented before and after

    Every job is photographed before and after, so you can see exactly what changed and keep it on file.

Common questions

Good to know.

How is this different from your holiday lighting service?

Permanent lighting is installed once and controlled from an app all year, so your eaves and rooflines are covered for every season. Holiday lighting is a seasonal hang and takedown, and it is still the better fit for wrapping trees, lining walkways, and big custom displays. Many homeowners do both: permanent on the house, seasonal on the landscape.

Can you see the lights during the day?

Barely. The LED points sit in a slim channel color-matched to your trim, so in daylight it reads as a clean edge along the roofline and only the light shows at night.

Can you install on a tall or steep roof?

Yes. Our crews work at roofline height on every service we offer, including three-story and steeply pitched homes, and they are trained and insured for exactly that.

What can I do with the app?

Set warm-white everyday lighting, pick holiday or game-day colors, build party scenes, adjust brightness, and schedule the lights to come on at dusk and off on a timer. You can change any of it in seconds.

Is it built for the PNW?

Yes. The system is weather-rated to run year-round through PNW rain, wind, and cold, and it is backed by a manufacturer warranty with support from the crew that installed it.
