Window Cleaning Report

Clean windows are a reflection of your home and once dust hits them, the beauty of their appearance fades. The surface of your window glass is porous and filled with peaks and valleys. They easily capture and trap airborne debris diminishing their quality and can lead to decreased RValue, or the measure of resistance to heat gain or loss of thermal pane windows. This is why hiring our professionals at DeMark's Window & Pressure Cleaning will help with making sure the quality of your windows is maintained.

House Washing Report

Your home is a place of relaxation and peace, but dirt and grime can leave you in despair. With the glamour gone, your home could be the eyesore that has turned the curb appeal off and made friends and family not want to visit. With our cleaning process, you will be able to regain the beauty of your home and leave the embarrassment behind.

Roof Wash Report

If the beauty and glory of your home are gone because of your dirty roof, it is time to clean it. A dirty roof can bring life to a standstill and create an unforgettable eyesore in your neighborhood. Our climate creates the perfect place for particular algae to grow. This is why our DeMark's cleaning professionals are the best at what they do.

Workers that came onsite were nice, but value of the service to the cost is not worth it at all. Definitely better gutter cleaning companies out there, and will never do business with this company again, nor recommend to colleagues or friends.

Needed windows cleaned on three story Tudor with leaded glass throughout. Greg, Ivan and Julio arrived at 830 and worked all day and the house looks great. They were meticulous and thorough and did a great job. I'll hire them again!

BEWARE. The facts: Received an unsolicited email and a text from Demark's Building Maintenance Solutions (Nick Demark) stating that my quote is ready for me and to click the link to open. I NEVER contacted this company and my contact information Nick used is highly private and safeguarded. Blocked and reported the phishing scam/spam.

After providing my address and contact information, I never heard back from this company. My request was for an estimate for mine and two neighbor's window washing. Very disappointed and would not recommend this company due to the lack of follow through.

A great company! It is not often that you are very pleased with a company that does work for you. I just had DeMark's clean my roof and I am very pleased. The workers were clean and considerate of my house and gardens. I will use them again. I also plan to use them for window cleaning.

I had Demarks come over to my 2 story home to clean our downspouts which were clogged. Two Demarks gentlemen came by on schedule, were very professional and cleaned out some heavily plugged gutters. They had proper equipment and were careful around our shrubs. I would definitely use them again.

I called this company in a panic to come out and clean my windows before blinds were being installed. They said they would be there and gave me a time frame. They came, on time, were quick, great clean and charged less than another company I had scheduled with previously. By the way, I had called 3 times to re-schedule the other company, larger, not better. No returned calls. Anyway, if you want a good reliable window cleaner, these are your guys:
