Caulking Services in Ajax, ON

Keep the water out.

Bathroom recaulking is one of the most common reasons Ajax homeowners call us. A two-storey house usually has more than one bathroom, and the original builder caulk in each tends to yellow and pull away around the same time. Our caulking services in Ajax cover tubs, showers, sinks, countertops and exterior joints. Every job starts with cutting the old bead out completely, down to a clean joint.

Tired Builder Caulk in Ajax Bathrooms

Many Ajax houses still have the caulking the builder ran at move-in, or a quick bead someone squeezed over it later. Neither holds. Caulk laid over old caulk peels within months and traps moisture underneath it. Black spots under the bead usually mean mildew has got behind, and the fix is to cut it all out, clean the joint with mildew remover and let it dry fully before new silicone goes in.

New bathroom fixtures are a popular Ajax upgrade, and caulking is part of finishing that job properly. A new vanity top needs a bead along the backsplash and wall, a new toilet needs a neat seal at the base, and shower trim needs sealing where it meets the surround. It's simpler to do it while the fixture is going in than to come back for it later.

Silicone needs a full 24 hours before the tub gets wet, which is easy to live with when there's a second bathroom down the hall. Bathtub caulking runs $75 to $150, the same as a shower, and a full bathroom with tub, sink, counter and toilet base is usually $150 to $250. Kitchen counters and backsplashes are $75 to $150. Small jobs are welcome too, with a $50 minimum.

Pedro handles caulking removal and replacement around tubs, showers, sinks and windows. For how he approaches caulking services in general, see our caulking services page.

How caulking services works

  1. Removal

    We cut and scrape out every bit of the old caulking. Anything left behind stops the new caulk from sticking properly, so we don't skip this.

  2. Clean and prep

    The joint is cleaned with a mildew remover and left to dry completely.

  3. Apply new caulk

    Wet areas get 100% silicone. Trim and exterior joints get a paintable acrylic-latex. Every bead is tooled smooth for a clean, professional finish.

  4. Cure time

    Silicone takes 24 hours to fully cure. We'll let you know when it's safe to use the tub or sink again.

Caulking Services in Ajax: FAQ

Do you offer caulking services in Ajax?

The caulk in our Ajax ensuite keeps going black within a year. What's causing it?

Usually it's moisture in a bathroom that doesn't dry out between showers. If the fan is weak or gets switched off right away, mildew grows on and under the bead. Caulk run over old caulk, or over a joint that was still damp, fails faster too. We cut everything out, treat the joint and use 100% silicone, and we'll mention it if the fan doesn't seem to be pulling much air.

Should the gap between my Ajax kitchen backsplash and countertop be caulked or grouted?

Caulked. That corner moves a little as the house shifts with the seasons, and grout there tends to crack. A bead of 100% silicone in a colour close to the grout keeps water from getting behind the backsplash and under the counter. If old grout has already cracked out of that joint, we rake it out first so the silicone sits in a clean gap.
