The Better Business Bureau is warning Alberta homeowners and businesses to be on guard against a paving scam that has been making the rounds across the province.

The scheme typically begins with an unsolicited knock at the door. A contractor introduces themself, claims to be working nearby and says they noticed the condition of your driveway or sidewalk.

Because they are already in the area with extra paving supplies, they say, they can offer a discounted price. If the homeowner agrees, the contractor asks for a large portion of the payment up front.

Red flags tend to emerge when questions are asked. The contractor may become evasive or hesitant when pressed for business details or pricing information.

Once payment is made, the scammer may simply disappear — phone numbers and email addresses prove unresponsive, and the company the contractor claimed to represent turns out to be unreachable or an impersonation.

In some cases the contractor returns and completes poor-quality work, but any attempt to seek a refund or correction goes nowhere.

The BBB also cautions that some fraudulent contractors resort to intimidation, including threats of legal action, to discourage homeowners from pushing back.

One consumer reported losing $5,000 through the scheme, telling BBB Scam Tracker: “Paving the driveway with recycled asphalt, came and put down crushed gravel and left. Said the crew was finishing a house around the corner and they’d come back but never did.”

How to protect yourself

The BBB recommends several precautions to avoid falling victim to contractor fraud.

Be wary of any unsolicited offer. Most contractor scams begin when someone volunteers an estimate that was never requested, particularly if it is framed as a limited-time discount.

Before hiring anyone, research the company online at BBB.org. A history of negative reviews or complaints is a strong signal to look elsewhere, and a basic internet search often surfaces prior fraud linked to a contractor or business name.

Get everything in writing before work begins. A signed contract should outline start and completion dates, a detailed description of the work, material costs, payment arrangements and warranty information.

Stagger payments rather than paying the full amount up front. Agreeing to pay in stages allows the work to be inspected before the next payment is released.

Choose safe payment methods. Credit cards offer the best protection since disputed charges can be reversed. If paying by cheque, make it out to the company, not an individual. Cash and electronic wallet apps offer no recourse if something goes wrong.

Homeowners and businesses who believe they have encountered a paving scam are encouraged to report it to BBB Scam Tracker at BBB.org.
