Missing evidence lowers the score because we can't check it. It doesn't mean it doesn't exist. Claiming a profile never changes the score. Evidence context, not a guarantee of workmanship.

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.
Ask to see a portfolio of completed work like yours, plus recent references you can contact.
