"Bill responded very quickly to my need to address a window with a broken “ sash”. He arrived when he said he would, he was very polite, patient, skilled and thorough, and, in a way that many people simply are not today. He also showed respect for my home, by being careful with his tools and any debris. I highly recommend Bill the Handyman."

"Worthington Basement Health Systems did an extremely professional and high quality job on the egress window and EZ-Breathe Ventilation System. The quality of their work is impressive and the window makes my basement bright and safe. The ventilation system has taken the musty smell away and I actually want to spend time in my basement. I highly recommend them for your basement needs."

"The installers were great. The salesperson made promises that he did not keep and he missed a window. When the person came to measure he also didn’t catch that I was having all my windows done except one. The windows look great. The response when I notified the co that one window was missed was very fast but added to my cost."
