Holiday Lighting in Mercer Island

Holiday Lighting in Mercer Island, WA

Mercer Island roofs are big. Many of these houses date to the 1960s through the 1980s, with wide planes and skylights up top, which is a lot of edge to light. Under the firs and madronas, with the lake right there, none of it dries out.

First Hill, Mercerdale and Mercerwood homes have the long low rooflines that reward one clean run. East Seattle, the North End and the South End have the tree cover that makes a lit tree worth doing on its own. Which of those suits your place is the first thing we sort out.

The lights are professional grade, sized and cut to your house in the colors you choose, so the runs look deliberate rather than store-bought. If a strand quits while the display is up, we come back for it.

Mercer Island questions

Who is actually on my roof?
Our own crews, insured and trained to work safely at roofline height. They are the same people who handle the rest of our work on the Island through the year.
Do you take all of it down, or just the roofline?
All of it. After the holidays we remove the whole display with nothing left for you to do, and we can hold it until next season.

Why it matters

The problem this solves.

Putting up holiday lights yourself means hours on a ladder in cold, wet, slippery PNW weather, fighting tangled strands and dead bulbs, then doing the whole thing in reverse in January after the magic has worn off. The spots that make a house look incredible, the roofline, the peaks, the tall trees, are exactly the ones that are hardest and least safe to reach on your own.

How we do it

Our approach.

It starts with a short design conversation: the colors you want, the look you are going for, and the features you want lit, whether that is a clean run along the roofline, the peaks and gables, the trees and walkways, or one statement tree. We size and custom-cut professional-grade lights to fit your home, so the runs look intentional rather than store-bought. Our crews hang them from roofline height the same way they handle every other job here, trained and insured for it, including tall and steeply pitched roofs. Through the season we come back and fix anything that fails, so your display never sits half dark. After the holidays we take it all down, and we can store everything until next year so your garage stays yours.

  • A design consult to plan the colors, the look, and which features to light
  • Professional-grade lights sized and custom-cut to your home, in the colors you choose
  • Roofline, peaks and gables, trees, walkways, and statement pieces like a single lit tree
  • Installation by insured crews trained to work safely at roofline height, including tall and steep roofs
  • In-season maintenance, so if a bulb or strand fails we come back and make it right
  • Takedown and removal after the holidays, with nothing left for you to do
  • Optional off-season storage, so your lights are ready to go next year
  • Christmas and Halloween displays both

Why WindowWorks

Who shows up matters.

Anyone can rent a pressure washer. After 20+ years on Eastside exteriors, and a 4.9 rating across 300+ reviews, we can tell you the real difference is the person holding the wand: what they know, how they were trained, and whether the company behind them takes care of them. We take care of our techs, so they take care of your property.

  • 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.

Do you provide the lights, or do I supply them?

We help you choose and source professional-grade lights, sized and cut to fit your home in the colors you want. If you have a specific bulb or look in mind, tell us and we will track it down.

Can you reach a tall or steeply pitched 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. If you have wanted lights up high for years without a safe way to do it, this is the service for that.

What if a light goes out during the season?

We come back and fix it. In-season maintenance is part of the service, so a failed bulb or strand does not leave your display half dark through the holidays.

Do you take the lights down too?

Yes. We remove everything after the holidays and can store it for you until next year, so there is no January ladder day and no box of tangled strands in your garage.

When should I book?

Early fall. We install through late fall and into December and the calendar fills, so reserving in September or October gets you both the date and the design you want.
