Top Rated & Trusted Power Washing Company in Maryland!

Alex is a true professional. Highly recommend using his services.

What a wonderful job, thanks again

Mr. Alex was prompt, explained the cleaning process and the after card in detail. Our awning looks like new and I will definitely hire him for future projects.

It was an easy experience, you will not be disappointed.

Alex was prompt explained what he was going to do. Very professional and friendly.

Checkmark did a great job power washing my house. Would recommend them to others. In fact my neighbor also used them and another neighbor got a quote.

Checkmark is transparent and honest in their work. They provide excellent customer service and attention to detail to ensure the job is done to your satisfaction.

Alex did an excellent job of performing the service and follow up. Alex also gave me some pointers on a DIY job and great recommendations on what products to use as well as the best way to do the job. Totally recommend!!!

Very professional service and super friendly workers. They use professional equipment, not a Home Depot power washer. Unlike other companies we've used, the mold hasn't come back and it's now been two seasons. This guy has it down to a science. The service was also very reasonably priced.

After purchasing our new home we needed a company to come in and clean up the grime of years of neglect. Checkmark was recommended to us by a friend and we were very happy from start to finish. Local, friendly and they followed up after the job.

Excellent results and great communication!

Alex with Checkmark is consistently professional in his customer engagement and attention to detail. He provides excellent service and does not cut corners. I can't recommend Checkmark enough.

Excellent! Great attention to detail, and knowledgeable regarding best practices for different surfaces. Did our home, walkways, and driveway in a timely manner and at a reasonable price.

Exceptional work and professionalism.

Checkmark Power Washing is a fantastic company which I have used three times in two years. I had my house & deck power washed in 2021 & 2022 and the siding & deck now look brand new. I also used Checkmark to power wash my wooden picket fence and 12 years of dirt and grim were washed away, giving me a brand-new fence. The owner, is professional, knowledgeable and does an incredible job! I give the company a five out of five for outstanding service.

Great company. Alex was awesome to work with and did a great job. Was highly knowledgeable and had all of the right equipment to get the job done. I would highly recommend Checkmark and will def use them in the future!

It was fantastic, it was better than I expected. I would recommend them to anyone.
