"Richard and his partner were total pro's at cleaning the windows in my house which is largely glass. They arrived at 9 AM and did not leave until 4 PM when all of my windows were PERFECT inside and out. EXCELLENT! And fairly priced — I will use them again!"

"Celtic Window Cleaning is awesome! My parents put their house on the market and thought they could wash the windows themselves. After trying and failing they decided to heed my advice and give Celtic Cleaner a call. They came out at the last minute and did an amazing job! Their customer service is the best in the industry!"

Solar Panel Cleaning

Did you know you must clean your solar panels to order to maximize efficiency?

If you are reading this section, you have likely invested in a clean solar energy setup, playing your part in protecting our planet so that our children and our children’s children can go on to enjoy it!

You have also conducted some smart business, knowing that the money you have spent is really an investment and that you will save money in the long run. But if your solar panels are unkept and dirty, they're not saving you as much money as they could.

At Celtic Window Cleaning we provide an effective method of cleaning solar panels — saving you the danger of cleaning them yourself! Request a free quotation via one of the buttons below:

roof cleaning project

Roof Cleaning

What’s on your roof? Moss, mildew, black streaks or other unknown substances? Have you ever wondered what these things could be doing to your roof?

As you know roof repair or replacement can be an expensive, time consuming and stressful procedure. So don’t let Joe and his pressure washer tear your shingles to shreds! A safe, tried and tested cleaning method can literally save you thousands of dollars in maintenance.

Our environmentally friendly products neutralize the acid that allows moss to take root and mildew to grow on your roof. Once neutralized, these potentially damaging things that plague us Washingtonians can be gently rinsed away and cleared up by our professionals. Our gold and platinum services come with 2 and 4 year warranties respectively, meaning that if anything green or gross (or both) should return to your roof within that time, we will return to remove it absolutely free!

aaaaa

"Outstanding work! Richard and his crew made our windows look the cleanest they have ever been. Also got all of the moss off our roof. Great job and highly recommend!"

"Richard at Celtic Window Cleaning did an amazing job cleaning our windows, screens and gutters. He also did a great job repairing screens that were damaged and sealing up our leaky gutters.

Richard is professional, hard working and extremely dedicated. He is totally trustworthy and really friendly. We highly recommend him!"

About The Owner

Richard was raised in the northeast of Scotland in the fair town of Banff. His love affair with window cleaning really started in London, where he mastered the skill while working for The London Window Cleaner. His former employers shine windows for the likes of Marriott hotels, the Victoria and Albert and British museums, and even Buckingham Palace!
In 2014 Richard married and relocated to Bellingham, where he embarked on his own window cleaning business, Celtic Window Cleaning. When not cleaning windows, Richard enjoys cycling, rugby, playing guitar, cooking, sampling our local breweries and talking about Scotland, Scottish culture and scotch!
