About Royal Windows and Gutters
A family owned, residential exterior cleaning company based in Covington, serving South King, Pierce and Thurston counties.
Our story
In 2014 our family visited the Puget Sound for a wedding. We instantly fell in love with the area. Having family in the area we decided to move in 2015 and after working with family doing the same thing, we decided to start our own business in 2018 and have enjoyed serving customers since.
We are a family owned business that started in 2018. We focus on South King County, Pierce and Thurston County. Our main focus is on Exterior Cleaning Services. We want our customers to feel that they are getting values for their money.
What we do
We are a family-run business that specializes in window cleaning, gutter cleaning, power washing, and exterior home maintenance. Our focus is on exterior home cleaning and making our customers happy. We have been in business since 2018 and we do what it takes to go the extra mile for our customers.
In practice that is eight services, all of them on the outside of a house. Window cleaning inside and out or outside only. Gutter cleaning, interior and exterior. Roof cleaning and moss removal, with the gutters and a moss treatment included. Driveway and patio cleaning. Soft washing for siding and roofs. Holiday lights along the roofline. A standalone moss treatment. And the screen clean upgrade that goes with a window cleaning.
Staying on the outside of the house is a decision, not a limit. It means the tools we own, the methods we have settled on and the things we have learned the hard way are all pointed at the same set of problems: rain, shade, conifers and what they do to a home over the years.
How we work
The single thing that separates good exterior work from expensive damage is matching the method to the surface.
Moss on a roof comes off by brushing. Not by pressure washing. An asphalt shingle is protected by a bonded layer of mineral granules, and a pressure washer takes those granules off along with the moss. It looks like a fast result and it costs you roof life you cannot get back.
Siding gets a soft wash. Low pressure plus a cleaning solution lifts the film off a wall without forcing water up under the laps, behind the trim or past a window seal, which is where pressure sends it.
Pressure belongs on driveways, walkways, patios and decks. Flat hard surfaces are built for weather, they collect organic growth on top rather than inside, and they are the one place where force is the right answer.
Gutters get the downspouts checked, not just the trough emptied, because a clean gutter with a plugged downspout still floods in the first real rain.
None of that is complicated. It just takes caring enough to do the slower version.
Where we work
We are a residential only company serving South King County, Pierce County and Thurston County. We are licensed, insured, and we guarantee our work. Reach out today for a free estimate.
We are based in Covington, and we work across the South Sound: Kent, Renton, Maple Valley, Auburn, Federal Way, Puyallup, Sammamish, Issaquah and Olympia among them. The full list is on our service areas page.
Residential only means what it says. Your home is the job we want, and it is the only kind of job we take.
Working with us
You can book online at any hour, or call during office hours and talk it through with a person. Either way you get a free estimate before anything is scheduled.
Window cleaning is priced per pane rather than by the house, so you can see what is being counted and pick which glass you want done. Gutter cleaning carries a 60 day warranty at no extra charge. The moss treatment we use on roofs is pet and plant safe.
Two things we offer that are worth knowing about. Active and retired military households get 10% off. And if you decide to get on a rotation and have the work done at the same time each year, we will lock your price for three years.
We take credit cards, debit cards, cash, check, Venmo and Zelle.
If you want the practical version of what we know, the blog is where we put it: why roof moss greens up the moment the rain returns, what fir needles do to a gutter, and why glass spots again two weeks after a cleaning.
When you are ready, book online or get in touch and tell us what the outside of your house needs.
