October 25, 2025 I contacted DeMark for a furnace quote and from the very beginning their sales representative was extremely helpful and straightforward. From calling them initially on Friday morning, they managed to book our installation the very next day on Saturday morning. We told them we had no heat in our home due to our old furnace break down and they did all they could to book us in ASAP. Their technicians were punctual, professional and clean. This team truly went above and beyond. Thank you!! !

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.
Look for consistent reviews across several named sources, not one polished profile.
