Resealing in Thornhill: why it matters

A reseal is one of the cheapest bathroom jobs there is, and it protects everything around the bath. Leaving failed sealant can let water cause damage that costs far more to fix. We do not add extras on the day. The price we quote from your photos is the price you pay, and if the damage turns out to be different, we discuss it before starting.

Bath resealing in Thornhill without replacing anything

We reseal baths with them filled with water, so the joint is at its widest, which stops the new seal tearing the first time the bath is used. Whether it’s black mould in the sealant and an untidy old seal, we can help, whatever the material.

A one-year guarantee comes as standard.

Work for landlords and builders

We carry out planned and one-off repairs for housing associations and facilities teams. Repairing in place avoids the disruption of a replacement, which matters when someone is living in the home.

Rental properties take more wear, and replacing things at every changeover adds up. A repair between tenancies is a cheaper way to keep the property in good order.

When to call us in Thornhill

Black mould is the most common reason people reseal. It grows into the silicone, so cleaning cannot get it all out.

Signs it’s time to call us include:

  • Unsealed corners
  • Mould you cannot clean out
  • An untidy old seal
  • Stained silicone

Choosing a repair company

How it works

It’s a tidy, low-fuss visit. We confirm the time with you beforehand, cover and mask the work area, and get on with the job, which normally takes about two hours for a bath. If anything looks different from your pictures, we’ll talk to you before going ahead.

  1. First we strip out every bit of the old mastic.
  2. We clean the joint and treat any mould.
  3. We dry the joint thoroughly.
  4. Baths are filled with water first, so the joint is at its widest.
  5. New mould-resistant silicone goes on and is tooled to a neat finish, taps included.

Preparing for the visit

  • Let us know which floor the room is on
  • Tell us about any previous repairs or coatings
  • Let the surface dry out before the visit

Thornhill questions

Will there be a smell?

There may be a mild smell during the work, which fades afterwards.

Is it worth repairing rather than replacing?

In most cases, yes. Replacement brings removal, refitting and making good, which a repair avoids. If it is not worth repairing, we will tell you.

How much does bath resealing cost in Thornhill?

Because every job differs, we price from photos. You’ll get a fixed figure before booking.

Can you do more than one item on the same visit?

Of course, and it generally saves money. Send pictures of everything together and you’ll get one combined price.

What happens next?

We come back with a fixed quote. You are under no obligation.

Can you quote from photos?

Nearly always. If photos do not show enough, we will ask for another angle.

I’m a tenant. Can you help?

Yes, but check with your landlord or agent first. Landlords are often glad to have it sorted before the end of a tenancy.

Is my repair covered?

Yes: twelve months. If anything goes wrong with the repair within the year, we return to fix it.

Aftercare tips

How the surface is treated afterwards matters:

  • Ventilate the bathroom well
  • Open a window after bathing
  • Clean the joints with a mild cleaner
  • Keep bottles off the joints

Avoid scraping the joints, and don’t stand bottles on the seal.

Reseal before water gets in. Gaps or lifting edges mean it needs doing.

Materials and what they mean for the repair

Baths

Baths are resealed with water in them, to open the joint fully.

Sinks and worktops

Basins, vanity units and kitchen worktops are resealed too, with the joint fully dried first.

Can I fix it myself?

What a professional repair adds is preparation, colour matching and finishing. We prepare the area properly, mix the colour on site and polish the finish to match, then guarantee it for a year.

DIY kits are sold for most surfaces, and they can make a small mark look better. The trouble is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler often lifts.

When we’d advise against a repair

A few problems are outside what a surface repair can do:

  • Water damage behind the bath that needs a builder
  • Very wide gaps that need a trim
  • A bath or tray that moves, until its support is fixed

If in doubt, send photos and we’ll say what we think before you book.

Surfaces we repair
