Building Washing in Redmond

Building Washing in Redmond, WA

Redmond changes material as you cross it. Older commercial around Grass Lawn and Education Hill, newer panel and stucco toward Overlake and Union Hill. What the wall is made of decides the pressure and the chemistry, so we confirm it on site and write it on the quote.

High pressure drives water behind panels and through window assemblies. EIFS and painted assemblies take damage that concrete shrugs off, which is why the substrate goes in writing alongside the method chosen against it. A year later that quote still says what the method was chosen against.

Along the Sammamish River and in Idylwood the extra lake humidity keeps walls damp, so growth is the usual complaint there. Buildings on the treed hillsides sit in shade for a good part of the day and do the same thing. Every elevation gets looked at before any of them gets priced.

Redmond questions

Is a wash safe on our EIFS?
Yes, at the right pressure. Pressure is what damages EIFS and painted assemblies, by forcing water behind panels and through window assemblies. We confirm the substrate on site and write it on the quote with the method chosen against it.
Nobody here knows what the building is clad in. Is that a problem?
No. Say so and we will establish it on the walk instead of guessing. The same goes for where your runoff ends up, which is the other thing owners often cannot answer.

Metal panel, EIFS, stucco, brick, precast, composite, painted wood, fiber cement and vinyl. Each one takes a different approach, and we confirm what your building is made of on site and put it in writing.

Why it matters

The problem this solves.

Everyone who comes to the property reads the outside first. A tenant weighing a renewal, a client arriving for a meeting, your CEO in town for the day, a board that wants to see the asset being looked after. What they take from it lands on you. The usual answer is a contractor who shows up, blocks the entrance, wakes the tenants, leaves hoses across the walkway and hands you the complaints afterwards. Now the building is clean and you have spent a week apologising for it.

How we do it

Our approach.

Washing a building people are using is going to be an inconvenience. Our job is to make it a known one. Before anything is scheduled we agree what the work involves, where the crew will be, what gets closed off and for how long, and who tells the tenants. Nobody finds out on the day. If a walkway has to be shut for an afternoon, you know that in advance and so do they. Our technicians are licensed, insured and trained for the work they are doing, and we provide the insurance certificate and any wording your site requires. What your board, your CEO and your clients see is a building that has been looked after, and a job that ran the way it was described.

  • The scope, the timing and the disruption agreed before anything is booked
  • Who tells the tenants, and when, settled up front
  • Landscaping, entries and drains protected or contained
  • Licensed and insured crews, with the certificate and any wording your site needs
  • A quote built from a walk of the property rather than a phone call

Add-ons

Add it while we're there.

The crew and equipment are already on site, so these attach to your visit.

Why WindowWorks

Who shows up matters.

Your tenants and customers see our crew before they see the results. Both will look professional.

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.

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.

What do you need from us to produce a quote?

A walk of the property, and whatever you already know about it: how we can reach the elevations, what the building is clad in, your work window, water and power on site, where the runoff goes, your insurance and site requirements, and who tells the tenants. Bring those and you get a number in one exchange instead of three. If you do not know one of them, say so and we will settle it on site rather than guess.

Is a wash safe on EIFS, stucco and panel systems?

Yes, at the right pressure. High pressure drives water behind panels and through window assemblies, and EIFS and painted assemblies take damage from pressure concrete shrugs off. That is why the substrate is confirmed on site and written on the quote, so there is a record of what the method was chosen against.

Can you work while the building is occupied?

Usually, and it depends on the building. Tenant-facing and public areas often move to after hours or a weekend, which carries a labor differential. Where the work has to happen during operating hours we say so, agree what gets closed off and for how long, and settle who tells the tenants and how much notice they get.

How tall can you go?

We reach it from the ground with poles, from ladders, or from a lift, so what matters is whether a lift can get to the elevation and what the site can take. Send us the address and we will tell you straight whether it is a fit, including when it is not.

Will an old chalked wall come back to looking new?

Sometimes, and not always. On an old chalked or oxidised wall we test a section first and show you what it gives back before you commit to the whole building. If the coating has failed, that is a repaint, and we will tell you that instead of selling you a wash that cannot fix it.

Can this go on a recurring agreement?

Yes, and most managed property does. No single interval fits an envelope, because shaded elevations grow back and street-facing elevations collect film at different rates, so the cadence gets set at the walk. One schedule, the same crew, and a documented maintenance record for the board file or the capital plan.
