## The honest read

Black Diamond Chimney cleans and inspects chimneys and installs wood stoves, pellet stoves and gas lines, and it holds a 4.9-star Google rating from 59 ratings. The company describes its work as chimney and venting solutions.

A recent customer said their gas fireplace kept blowing out its pilot light until Brandon completely tore down the unit, found multiple issues causing the problem and corrected them. A recent customer said Brandon installed a gas line to a new stove, with the work exactly as quoted. A recent customer said Brandon installed a wood stove and chimney, made sure all piping was properly sealed, and returned after two years of daily winter use to clean the chimney, leaving the work area tidy. A recent customer said Brandon answered questions about pellet stoves and then installed one.

A 2026 customer wrote that other companies said a water-damaged chimney had to come down and be replaced, while Brandon offered another option: venting the pellet stove to the outside, which saved thousands of dollars. A 2025 customer said an inspection found issues from a previous chimney fire and a structure not up to code, and the quoted full tear-down and replacement was covered by their insurance company due to the fire hazard. A 2024 customer said Brandon Masse inspected their chimney top to bottom and shared photos of everything that needed attention.

A 2026 customer whose pellet stove stopped working two weeks after Brandon serviced it said the visit ended with "Your pellet stove is dead" and a $300 diagnostic fee for a 5 minute visit, and that Brandon was rude and dismissive when they complained. A 2025 customer who had a wood-burning fireplace converted to propane said they would have preferred more timely communication while waiting for components to arrive, after putting a lot of money down in advance.

**Strengths:**
- Gas fireplace repair — a recent customer said multiple issues were found and corrected
- Gas line install — a recent customer said the work matched the quote
- Wood stove install — a recent customer said all piping was properly sealed
- Photo-backed inspection — a 2024 customer was shown what needed attention

**Concerns:**
- $300 diagnostic fee — a 2026 customer called it excessive for 5 minutes
- Delay communication — a 2025 customer wanted earlier word on component delays
