What to check before hiring a bathroom renovation company in Markham

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

    Building permits for homes in Markham come from the City of Markham, and moving fixtures or drains, adding a bathroom or changing circuits 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.

Bathroom renovations in Markham: common questions

What makes a bathroom renovation go wrong?

Water. A shower that is not properly waterproofed behind the tile can leak into the walls for years before anyone notices. Ask which waterproofing system the firm uses and how it handles the shower floor and the joints.

Do I need a permit for a bathroom renovation?

A like-for-like update usually does not. Moving the toilet, shower or drains, adding a bathroom, or changing electrical circuits generally does. Your municipality decides, so confirm before work starts.

Can a bathtub be replaced with a walk-in shower?

Usually. The firm removes the tub, reworks the drain for a shower, waterproofs the walls and floor, and builds or sets the shower base. Ask how it will handle the drain position and the waterproofing at the shower entry, especially for a curbless shower.

What is the difference between a bathroom renovation and a refit?

A renovation strips the room back to the studs and rebuilds it, which is the chance to fix hidden water damage, move fixtures and redo the waterproofing. A refit replaces fixtures and finishes in place. A refit is quicker, but it cannot fix problems behind the walls.

How do I check that a contractor in Markham 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 Markham?

Building permits for homes in Markham come from the City of Markham. For bathroom renovation, moving fixtures or drains, adding a bathroom or changing circuits usually needs one. Many firms apply for the permit as part of the job, so agree who does it before you sign.
