10/10

The house I purchased had the old roof with two layers of shingles. Once I found in my mailbox the paper from Alpha Roofing with the approximate estimation of work especially for my house. I liked the price, called Sandy Jiao and never regret about that. Roof was replaced during one working day with the excellent quality and 50 years warranty for shingles and 10 years warranty for labor.

The house we purchased in Mississauga had a poor layer of insulating stuff. I've found "Great Northern Insulation" company in internet. Mike came at the same day I called, made the estimation and scheduled the date of work. All was done exactly as promised, quickly and with the excellent quality. Now I'm paying for heat significantly less than before. Good work, guys!
