Bathroom Repairs in Newmarket

Four repair calls we answer every week in Newmarket

Not every phone call we get in Newmarket starts as a planned style upgrade. Many begin when a homeowner spots a brown ring spreading across the kitchen ceiling, steps on a spongy bathroom floor tile, or realizes a newly tiled shower was built without a waterproof membrane. Across Newmarket’s older streets and 1990s subdivisions, four repair problems come up repeatedly:

1. Water stains or active drips on the main-floor ceiling directly underneath an upstairs ensuite or hall bathroom.
2. Showers that leak through grout seams, hold standing puddles, or have loose tiles, often just a couple of years after a rushed renovation.
3. Peeling ceiling paint, black mildew in corners, and frosty attic sheathing caused by weak or unvented bathroom exhaust fans in 1960s–1990s homes.
4. Incomplete or defective renovations left behind by another contractor, where the homeowner needs a straight answer on what can be salvaged and what must be torn out.

Smearing extra silicone over cracked grout or painting stain-blocker on a wet ceiling never solves a plumbing or membrane failure—the fix has to happen where the water is escaping.

How we trace a water stain on the ceiling below

When a damp patch appears on your living room, dining room or kitchen ceiling beneath a bathroom in Stonehaven, Glenway, Armitage or Bristol-London, the water is almost always escaping from one of four spots:

• A failed toilet wax seal or loose flange, or a worn gasket on a bathtub waste-and-overflow shoe.
• A cracked fibreglass shower base or a tiled shower pan built without a bonded waterproof membrane.
• Separated caulking or missing grout around a low shower niche, corner bench or mixing valve escutcheon.
• A weeping copper solder joint, worn cartridge or pinhole supply leak inside the wet wall, which drips steadily even when the shower is turned off.

We isolate the cause methodically rather than guessing. First we check whether the stain grows continuously (pointing to a pressurized supply pipe) or only after someone showers or drains the tub. Next we test the drain trap in isolation before wetting the lower walls. Where the pipe sits above a finished drywall ceiling, opening a neat access square from below lets us inspect the subfloor and trap directly without smashing intact bathroom tile. Once the source is confirmed, we quote both the bathroom repair and the ceiling restoration in writing.

Rebuilding leaking or poorly sloped tiled showers

When a tiled shower starts leaking into the framing or hallway baseboard within a few years of being built, surface regrouting will not save it. Opening the base almost always reveals the same shortcuts: ceramic tile glued straight onto bare drywall, a flat mortar pan with no pre-slope to the drain, an unsealed curb framed out of untreated 2x4s, or no waterproofing membrane around the niche.

Our crew strips the failed section down to clean studs, dries and repairs any rotted framing or subfloor, and rebuilds the enclosure using waterproof foam backer board, a properly pitched pan, and a continuous sheet membrane sealed to the drain flange—the same system used on all our walk-in showers in Newmarket.

Fixing bathroom mould and attic-vented exhaust fans

In many 1970s and 1980s houses across Gorham-College Manor, Huron Heights, Bristol-London and Armitage, the original bathroom fan either rattles loudly while barely pulling a sheet of tissue paper, or vents warm, wet air through an uninsulated flex hose dumped right into the attic insulation. In winter, that moisture condenses on cold roof plywood and drips back onto the ceiling drywall.

Replacing an exhaust fan and running an insulated duct to a proper exterior wall or roof hood is a standalone repair we handle regularly, and it stops surface mildew at its source. Where moisture has already rotted drywall along a tub rim, we cut out the damaged board, treat the framing, and rebuild the surround with waterproof materials.

Rescuing stalled or botched contractor work

Calling a second company after a contractor disappears mid-job or builds a shower that fails inspection is frustrating. As Newmarket homeowner Lawrence noted in our client reviews, what matters most is a crew that addresses every issue pointed out and stays until the job is properly finished.

We inspect the existing work, explain clearly which rough-ins or fixtures can be kept and what must come out, and provide an itemized written quote. If the previous crew moved drains without a municipal permit, read our guide to Newmarket bathroom renovation permits and our checklist on how to vet a bathroom contractor in Newmarket.

How bathroom repairs are priced in Newmarket

Because repair scopes vary from a two-hour valve and fan fix to a full shower pan rebuild, we price repair jobs by the specific work required. As published benchmarks from our Newmarket bathroom renovation cost guide, licensed plumbing and electrical trades run $70 to $120 per hour, and full room strip-out and disposal is about $1,500. When hidden water damage means the whole room is better rebuilt from scratch, we price the project from our published full bathroom renovation or tub-to-shower conversion packages starting at $8,000 in labour.
