"The owner, Ben, did an outstanding job cleaning our residential windows (his company also does commercial window cleaning). To date we have used him twice. Sea-Thru Window Cleaning communicates very well with their customers - before, during and after. The result is appointments are kept and reminders for future cleanings are provided. I highly recommend Sea-Thru Window Cleaning - you will be amazed of the results."

"am very pleased with home Genius and its crew. Every single person from project management on down was very pleasant, and offered answers to all my questions. They worked together as a team and didn’t just put the 3 bay windows in, they talked to each other and made sure everything was being put in evenly carefully and completely. Kudos!!!! Thank you all!!!"

"Super fantastically well. Patsy Cicala and his crew were excellent. The windows were custom and had a trapezoid shape and they installed them perfectly from beginning to end. They weren't replacing windows but instead creating new ones and had to cut through my wall. It took about 2 days since they worked all day long for both days. The windows look terrific and my home was cleaned up from the minor mess. Patsy and crew were wonderful to deal with. The price was incredibly fair. I would hire Patsy again without question. Plus, he is fun to be around!"

"Tara was very responsive when I asked for a quote. We were moving out of our house and needed someone to clean the house for us once we moved. Tara came earlier than originally scheduled (as we agreed on) and it worked out great for me. She was fast and did a great job!! I would definitely recommend Tara if you are needing your house cleaned!!"
