Excellent job installing engineered hardwood, soundproofing, & remodelling a new bathroom. They worked with my designs & collaborated on my ideas. They got me great deals on materials.

Chris5.0 / 5 ·

We hired CMM to supply and install newel posts, spindles and railings only. My wife and I sanded, stained/painted the railings, risers, stringers and steps ourselves. The job was completed in one day, we are overall happy with the workmanship and would recommend this contractor.

Jerry tore out my old shower which had water damage, fixed the walls, redid the plumbing, and put in a new shower and tiling. Also did the floor tiling in the bathrooms and repainted and redid drywall. The shower was great. Jerry did the project on time and in budget. He is very communicative, sent pics ever day of the progress. I would work with Jerry again and strongly recommend.

What to check before you hire

Worth checking yourself
Only a few public reviews are shown. Ask for recent references you can contact.
Their public evidence comes from a single source. Look them up on another site before deciding.
No credentials are shown here and the business has not claimed this profile. Ask to see certificates and insurance directly.
Trade licensing in Canada is set by each province or territory. Electrical, gas and plumbing are licensed trades almost everywhere (for example ESA for electrical and TSSA for gas in Ontario), so check your provincial regulator that the contractor is certified for the work before you hire.
A construction lien is a real risk: in every province an unpaid subcontractor or supplier can register a lien against your home even if you already paid the main contractor. Hold back the statutory amount (commonly around 10%) and get signed lien waivers as you pay.
Confirm they cover your area and can actually come out in your timeframe before anything else.
