## In customers' own words
_Verbatim quotes from this contractor's public reviews, each attributed to its source:_
> "Took a little longer than we thought but Leo had to travel from Kanata to North Russell. Leo worked alone (hard worker) and did a fantastic job on our basement floor laying down porcelin tile and repairing some insulation and drywall. I sent him over to my son's house in Osgoode to repair his cement steps out front. We would highly endorse Leo for your next reno job we are even considering to have him build a new deck next spring."

They painted a 2,000 sq. ft. bungalow with 3 bdrms, 1 hallway, foyer, living rm and mantel shelves, 2 bathrooms and cabinets with some repairs, 5 closets with rebuilt shelving and 3 closet hangers, 3 new doors with casings and hardware and painted, 5 pairs of bi-fold doors with casings and knobs and painted. They repaired and painted 2 areas that were in need of drywall remediation. They removed carpets and installed new flooring and 1/4 round throughout, including 1/2 bathroom. They met all our requirements and followed up on every concern. They are honest and reliable and I will recommend them."

## Before you hire a hvac contractor
_What to check when choosing this kind of trade (general guidance, not a claim about this business):_
- 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.
- Read recent reviews for reliability and turning up on time, not only the quality of the work.
- Agree the call-out fee up front, and be wary of large upfront deposits for an emergency job.
