A chimney cap keeps rain, snow, animals, and debris out of your flue in Cedar Grove, Markham. A chimney without a cap is an open pipe pointed at your fireplace — birds nest in it every spring, and water pours into it every rainstorm.

Why chimney cap installation matters in Cedar Grove, Markham

Animal Prevention

Raccoons, squirrels, and chimney swifts nest in uncapped flues every year in Cedar Grove, Markham.

Chimney Cap Installation reviews in Cedar Grove, Markham

4.9 average from 743 verified customer reviews
Level 2 for a house sale
Recorded the whole flue on video for the buyer's agent. The chimney line item stopped being a negotiation point the same day.
Tom H. - Markham - 2026-04-03
Good work, tight scheduling
Had to move my appointment once, but the sweep itself was excellent and the crown sealing has held through the winter with no water staining.
Greg W. - Burlington - 2025-10-21
Second flue done same visit
Old house with a furnace flue as well. They handled both in one visit and discounted the second one rather than charging full price twice.

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.
