What to check before hiring a basement renovation company in Kitchener

Five things to confirm with any firm, on this list or not, before you sign. The rules below are Ontario's and Kitchener's.

  1. Registration with the WSIB

    Ask the firm for a clearance certificate from the WSIB, which confirms it is registered for workers' compensation and its account is in good standing. The certificate confirms the firm is registered with the WSIB and up to date on its premiums, so check its dates cover your job.

  2. Liability insurance

    Ask for a certificate of insurance that names the firm and shows commercial general liability coverage in force for the dates of your job, and check that the subcontractors it brings in are covered too.

  3. The building permit from Kitchener

    Building permits for homes in Kitchener come from the City of Kitchener, and finishing a basement or adding a secondary suite usually needs one. Agree in writing who applies for the permit and books the inspections.

  4. A written contract

    Get the scope of work, the payment schedule tied to stages of the work, start and finish dates, how changes are agreed and priced, and who handles permits and cleanup, all in one signed contract before any work starts.

  5. The warranty

    A renovation is not a new home, so the new home warranty rules usually do not apply: get the firm's own workmanship warranty in writing, with what it covers and for how long. Renovators in RenoMark, the Canadian Home Builders' Association program, offer a minimum two-year warranty on their work.

Basement renovations in Kitchener: common questions

What is basement development?

It is the term Alberta builders and homeowners use for finishing an unfinished basement: framing, insulation, electrical, plumbing, drywall and flooring, often with a bedroom, bathroom or family room. Elsewhere it is usually called a basement renovation or basement finishing.

Can I add a legal suite in my basement?

In many Canadian cities, yes, but a legal secondary suite has to meet the building code and local zoning, including a separate entrance, ceiling heights, fire separation, smoke alarms and egress windows. It needs a permit and inspections, so ask the firm whether it has built legal suites in your city.

How do I keep a finished basement dry?

Deal with water before finishing: grading and downspouts that carry water away from the house, a working sump pump where the house has one, and repairs to foundation cracks. Then insulate and frame in a way that handles moisture. Ask the firm what it checks before it starts framing.

Can I add a bathroom in my basement?

Usually. A basement bathroom needs a drain connection, which can mean breaking the concrete floor to reach the main drain, or a pump system where the drain sits higher than the floor. The plumbing work needs a permit and inspection.

How do I check that a contractor in Kitchener is registered with WSIB?

Ask the firm for a clearance certificate from the WSIB. The certificate confirms the firm is registered with the WSIB and up to date on its premiums, so check its dates cover your job.

Who issues building permits in Kitchener?

Building permits for homes in Kitchener come from the City of Kitchener. For basement renovation, finishing a basement or adding a secondary suite usually needs one. Many firms apply for the permit as part of the job, so agree who does it before you sign.
