Do you need bath resealing in Gremista?

Most reseals are because of black mould. It grows into the sealant itself, so cleaning cannot get it all out.

These are the problems we are asked about most:

  • Sealant that is split or lifting
  • Silicone smeared on tiles
  • Damp near the bath
  • Mould you cannot clean out

What to look for in a quote

  • What aftercare is recommended
  • Whether they match the colour on site
  • What happens if the damage is worse than the pictures show
  • Is the price fixed, and does it include VAT?

10 questions to ask before booking

Different materials, different repairs

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, once the joint is completely dry.

Should I try a DIY kit first?

Kits are cheap and easy to find, but many of the jobs we do start with putting right a DIY repair. Doing it properly first is typically the cheaper route.

A DIY attempt is not a disaster. We take the old repair out and do it properly, so it will not stop us repairing it. It does add a little time, so tell us about it when you send photos.

What we do, step by step

When we visit, we arrive at the time we’ve agreed, cover the area with dust sheets and masking, and set to work. Expect it to take a couple of hours. We clean up when we are done and tell you when it’s ready to use.

  1. The old silicone is cut out completely.
  2. We remove the residue and clean the joint.
  3. Any mould is treated and the joint dried.
  4. The bath is filled with water, or weight put on the tray.
  5. We apply fresh mould-resistant silicone and tool a neat bead.

Getting ready for the visit

  • Avoid using the area for a few hours before we arrive
  • Point us to the nearest place to park
  • Clear toiletries, mats and anything else from around the area

Ask for a price

The quickest way to a price is to send two or three photos through our quote form or ring us. We’ll tell you honestly if a repair is the right fix.

Your questions about bath resealing in Gremista

Is there any odour?

There may be a mild smell during the work.

Is it worth repairing rather than replacing?

Generally, yes. Replacement brings removal, refitting and making good, which a repair avoids. If it is not worth repairing, we’ll tell you.

Do I have to be there?

Someone needs to let us in and show us the job. After that, you can carry on with your day.

Why does my sealant keep going mouldy?

Mould needs moisture. Run the fan, dry the joints and the new seal stays cleaner for longer.

Do you hold any accreditations?

Yes, including CHAS, Constructionline and SafeContractor. The full list is on our accreditations page.

Can you repair something that is been repaired before?

Generally, yes. Tell us what was done before.

How soon can you come?

It depends on the time of year and where you are. We will offer you dates when we send your quote.

Do you do work for letting agents?

Yes. We carry out repairs for homeowners, landlords, letting agents, builders and businesses in Gremista.

What affects the price in Gremista

Each job gets its own fixed price. This is what makes a difference:

  • Whether we combine several jobs
  • Unusual colours or finishes
  • Any earlier repairs that need removing first
  • What kind of damage it is

Most people are surprised how affordable a repair is, particularly next to the cost of replacement. Photos let us give you the exact figure.

Quotes from your pictures

Photographing the damage takes a minute. Try to send:

  • The material, if you know it
  • A picture taken from further back
  • The postcode, so we can plan the visit
  • Whether it’s been repaired or coated before

Getting a quote takes a couple of minutes: photograph the damage, then the whole bath or shower, add your postcode and send them over. You’ll get a fixed price, not an estimate.

When we’d advise against a repair

Some jobs aren’t right for a repair, including:

  • Hollow or loose tiles
  • Very wide gaps that need a trim
  • Water damage behind the bath that needs a builder

Not sure? Send pictures and we will give you a straight answer.

Materials we repair

  • Kitchen worktops & sinks
  • Wet rooms
  • Baths
  • Basins & vanity units
  • Shower trays & enclosures

Landlords, agents and businesses in Gremista

For anyone letting property in or around Gremista, we’ll quote for several properties at once. Just send pictures for each address and we will price them together.

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.
