What Our Customers Say
"Someone used acid to tag our glass front door. Steve was very patient with us and worked with us to facilitate our long business hours and got the job done on a weekend after we closed. Really happy with the work he did -- and although I hope I don't need his services again, he'll be the first person I'll call if I do."
"Steve was fabulous!!! We’re actually sitting outside eating now and can’t stop staring in awe at how amazing our siding looks. I’m still shocked at the clear view every time I look at the windows when I walk downstairs. They were timely and efficient. As a middle aged woman, I felt completely comfortable giving his team access to my home. We will definitely be using PEC again! Thanks so much!!!"
"Great timely, friendly service. I called Steve today, and he was able to get my window screens and patio door repaired. I would highly recommend him for your window needs!"
"My windows have never looked better!"
Spotless inside and out, with a team that was respectful of the home throughout the job.
