John McLellan Contracting Inc.

We had a leak for several years above the sliding doors in our kitchen, during only certain kinds of windy rainfall. Each time we thought we found & fixed the problem, we'd learn a few months later we didn't
We'd been given John's name as a recommendation for leakage/windows concerns, and he did not disappoint! John arrived at our Oshawa home & diagnosed the problem within minutes, and a crew was able to come a couple months later to repair and re-side the troubled west wall over a two-day period -- JUST in time for that awful pre-Christmas rain/snow storm. The experience was great - from John on down. His whole team was professional, competent & personable. And he guarantees his work. We would use McLellan Contracting again, and highly recommend!
