What to Look for When Hiring a Contractor

Liability Insurance

A professional contractor will have insurance coverage, particularly liability and workers’ compensation.

Otherwise, you could be held liable for damages to your property that they caused as well as for personal injury to the contractor.

WSIB Coverage

WSIB stands for Workplace Safety & Insurance Board. Make sure your contractor carry’s full WSIB coverage.

If a worker gets injured on your property and the contractor doesn’t carry a full WSIB coverage, you could be held liable for all injuries.

Warranties for your job

There are workmanship warranties which are provided by the contractor and typically run from 1 year to 10 years. This warranty covers the installation.

There will also be a material warranty which is offered by the manufacturer of the products and those warranties vary depending on the products being installed.

Get the Contract in Writing

Ask for a written contract with the total estimated cost for your project. Including materials, labor, dump costs and any extra’s for unforeseen issues.

This keeps your contractor accountable and ensures they stick to the project specifications without any hidden fees…

Amazing work! Very pleased with the results. Professional and timely. Wouldn’t hesitate to hire them again. Thanks for the great work.


I lost shingles in a bad wind storm and they were there very quickly and the repair looks great! Thank you so much! When my roof is due to be replaced they will be my first call!


We upgraded our vinyl siding to a premium engineered siding (Celect). Excellent work overall. Great communication, timely, on budget and the finished product is high quality. Alteck picked up two other jobs adjoining our house based on their work product. I highly recommend!
