What to check before hiring a basement renovation company in Langley

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

  1. Registration with WorkSafeBC

    Ask the firm for a clearance letter from WorkSafeBC, which confirms it is registered for workers' compensation and its account is in good standing. The letter is free online and shows whether the firm is registered and paying its premiums; WorkSafeBC warns that a homeowner who hires an unregistered firm can be held liable for premiums owed on the work.

  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 Langley

    Building permits for homes in Langley come from the City of Langley or the Township of Langley, depending on the address, 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 Langley: 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 Langley is registered with WorkSafeBC?

Ask the firm for a clearance letter from WorkSafeBC. The letter is free online and shows whether the firm is registered and paying its premiums; WorkSafeBC warns that a homeowner who hires an unregistered firm can be held liable for premiums owed on the work.

Who issues building permits in Langley?

Building permits for homes in Langley come from the City of Langley or the Township of Langley, depending on the address. 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.
