DeMark's, LLC

Morgan did a great job.

The men arrived earlier than expected which was great. Andrew and Miguel were very professional and did an excellent job cleaning my very dirty windows inside and out. Will have them again and will recommend them to every one I know. Jim and Carol from Lake Mills, Wi.

Excellent job! Would definetly hire again.

Didn't bring the right ladders . Showed up a bit late. Not a very professional 'look' or manner (vehicle and staff).

Everyone was very professional

They were clean and efficient. The windows look great

The crew did work on a difficult job.

Excellent job on all the windows and screens, and especially the white sills in and out. We never have to look for another company. Franciscan Sisters

We are extremely pleased with the services provided. Our windows are clean and clear beyond our expectations! The three gentlemen who performed the work were pleasant, respectful and friendly and took great care in keeping our home neat and clean.

Everyone I had contact with was courteous and professional. They did great work on an old house with difficult windows. I will hire them again.

The cost was a lot more than I have paid in the past to another company, but the work quality and customer service were great.

Did a great job.

I have already given the company name to two other people. Fantastic job and I will be using them in the spring.

DeMark's did a great job cleaning the windows of our new house. They expected our exception and we are glad we chose them.

I was told 2 people would be out and it would take about 2 hours. Only 1 man showed up and it took about 4 hours. Fortunately, I didn't have to leave for another appointment, but would have preferred knowing how much time I really had to set aside for this service. The work was outstanding.

Great business. Did not damage house nor take trim paint off. Was the most expensive of the three companies I got estimates on by about a hundred dollars, but also most professional. You get what you pay for. Team got 90% of the house clean, and to be fair the other 10% I don't know if they could get clean as it may be from discoloration or needing to hand scrub which they do not do. Recommend the company. Nice folks. Do not take Credit Cards. Cash or Check only.

They also pressure wash your building if needed. We had a big spot on the building and they worked really hard to get it all off.

We are thrill to have found a good service. We are definitely putting them on a regular schedule. Thank you so much for providing this service. You facilitated our process for us to find a good and professional service. Thank you Home Advisor!
