Why chimney leak repair matters in Downtown Guelph, Guelph

Diagnosis First

Anyone who quotes a chimney leak repair without going up on the roof is guessing. We inspect before quoting.

Water Path Tracing

Water can enter at the cap and appear on a ceiling six feet away. Proper diagnosis follows the actual path.

4.9 average from 743 verified customer reviews
Exceptional chimney inspection
Punctual, professional, and walked me through every step. The report came the same afternoon with clear photos of the crown cracks they found. No pressure to book the repair.
Sarah M. - Toronto - 2026-05-14
Raccoon eviction and cap fitted
Family of raccoons in the flue. They removed them humanely, cleaned everything, and fitted a stainless guard that has kept them out since.
Alicia D. - Ajax - 2026-02-25
Camera scan caught a cracked tile
Previous company swept and said everything was fine. Diamond ran a camera and showed me a cracked liner tile on screen. Glad I got the second opinion.
Marta S. - Mississauga - 2025-11-30
Post-fire inspection
Small flue fire in January. They inspected, documented the damage, and coordinated the report with my insurer without me chasing anyone.
