Downspout Extensions you can actually trust
Toronto basements leak because the downspout dumps water at the foundation. We install flip-up extensions, buried PVC to a pop-up emitter, or splash blocks — sized so every drop lands at least 6 feet from the wall on a downhill slope.
Every Markham job is quoted in writing before any work begins, and backed by a 5-year workmanship warranty.
