How to Vet a Bathroom Contractor in Aurora

With so many renovation companies advertising in York Region, choosing the right team for your Aurora bathroom can feel overwhelming when one estimator scribbles a single total on a notepad and another offers a steep discount for cash without paperwork. Because the waterproofing membrane, drain pitch, venting and electrical junctions that protect your house from water damage are covered up by porcelain tile within the first two weeks, verifying a company’s credentials and construction methods before you sign is essential. Run every bidder you interview—including us—through the seven checks below so you can rest assured your home is in capable hands.

1. Verify WSIB clearance, liability insurance, ESA licensing and provincial records

Active WSIB clearance certificate. In Ontario, construction businesses and independent operators are required by law to carry Workplace Safety and Insurance Board coverage (with narrow statutory exceptions). Source: Government of Ontario: Your rights when starting home renovations or repairs (accessed November 7, 2026) Ask each contractor for a current WSIB clearance certificate and check the certificate number on the WSIB online portal prior to demolition.

Commercial general liability insurance. Ask for an insurance certificate showing the exact legal or operating company name listed on your contract. If you are renovating a suite in a Yonge Street, Wellington Street or Bayview Avenue condominium building, the property manager will require this certificate—naming the condominium corporation as an additional insured—before approving your small or condo bathroom renovation.

Ontario Consumer Beware List. Search both the company name and the owner’s name on the Government of Ontario’s Consumer Beware List to make sure there are no unresolved Ministry compliance orders or Consumer Protection Act convictions.

Licensed Electrical Contractor (ESA). Under Ontario law, only a Licensed Electrical Contractor (LEC) registered with the Electrical Safety Authority is permitted to install bathroom pot lights, GFCI receptacles, heated-floor thermostats or exhaust fan wiring for hire. You can look up an electrical licence in under a minute on the ESA Contractor Locator. Source: Electrical Safety Authority: Contractor locator (accessed November 7, 2026)

2. Insist on line-by-line written quotes, not one-line totals

Ontario consumer guidance recommends getting written estimates from multiple contractors and comparing the exact construction tasks included by each. A trustworthy bathroom quote breaks out demolition and disposal, rough plumbing, electrical, framing, waterproofing membrane, tile setting, vanity installation and custom shower glass on separate lines, and separates installation labour from finish materials. Visit our Aurora bathroom renovation cost page to see how we publish our labour packages and line items.

Watch out for vague lump-sum quotes. When an estimate leaves out fundamentals—such as replacing seized shut-off valves, installing 2x8 wood blocking for grab bars, or ducting an old attic fan to an exterior hood—those steps either get skipped behind the drywall or turn into expensive change orders mid-project.

Photo quote first, in-home verification before signing

Requesting a written quote from your bathroom photos first—as we do in our 5-step renovation process—is an efficient way to confirm that a contractor’s pricing fits your budget before booking home visits. Once you are ready to move forward, provincial consumer rules advise never signing a binding renovation contract until the contractor has visited your house, measured the room in person, and confirmed the written estimate on site.

3. Attach the itemized estimate to your contract (Ontario’s 10% cap)

Under Ontario’s Consumer Protection Act, when a written estimate forms part of your signed home renovation agreement, the contractor cannot legally charge more than 10% above the agreed estimate unless you agree in writing to new or changed work.

Every residential renovation contract over $50 in Ontario must be in writing and include: Source: Government of Ontario: Your rights when starting home renovations or repairs (accessed November 7, 2026)

• The contractor’s legal business name, street address and telephone number (see our about page and terms of use).
• A complete itemized description of the construction work and any materials supplied.
• The total contract price including HST, initial deposit and milestone payment schedule.
• Planned start and completion dates.
• Clear written labour warranty terms and daily floor protection and debris disposal commitments.

For an Aurora bathroom remodel, make sure the agreement also states who prepares and submits the application if the layout requires a municipal building or plumbing permit; read our article on Aurora bathroom renovation permits.

4. Keep the initial deposit modest and pay by completed stage

Provincial consumer guidance recommends keeping initial deposits reasonable—around 10%—and linking each progress payment to a physical stage you can inspect in your home: demolition and framing finished, rough plumbing and electrical passed, waterproofing and tile set, and final walkthrough complete. Never pay the final balance before the completion walkthrough, and keep a receipt for every payment.

5. Know your 10-day cooling-off cancellation right

When you sign a residential renovation contract worth $50 or more at your home in Ontario, the Consumer Protection Act gives you a 10-day cooling-off period during which you can cancel the agreement in writing for any reason without penalty.

6. Ask how they waterproof showers before tile is set

Most of the costly bathroom repair calls we handle in Aurora involve showers that were tiled straight onto bare drywall or an unsealed mortar bed. Before hiring any company to build a walk-in shower, ask four direct questions:

1. Which waterproof backer board and sheet or liquid membrane system do you bond behind the shower tile?
2. How do you seal inside corners, the shampoo niche, the bench top and the drain flange?
3. How do you inspect upstairs floor joists before promising a recessed curbless shower entry?
4. Will you share job-site photographs showing your showers at the membrane and tile-levelling stage?

An experienced bathroom crew will answer right away and show you real project photos. You can browse our completed rooms across our before and after gallery, including our freestanding tub and pebble-floor primary bathroom and frameless marble walk-in shower case study.

7. Look for specific, verifiable homeowner reviews

Read client testimonials that talk about communication, tile setting quality, cleanliness and how end-of-job adjustments were handled—like the York Region and GTA reviews on our client reviews page.
