Bath resealing in Margam

Bath resealing in Margam, done in place

The key to a good reseal is getting all of the old silicone out. Fresh sealant doesn’t stick to old, which is why so many DIY reseals peel. We work on kitchen worktops & sinks, wet rooms and basins & vanity units, and common reasons people get in touch are gaps by the taps and mould you can’t clean out.

All of our repairs are guaranteed for twelve months. We return to put right any problem with the work.

Should I try a DIY kit first?

We understand the appeal of fixing it yourself. The trouble is that kit repairs frequently look fine at first and then fail, and the old filler has to come out before a proper repair.

For a hairline mark somewhere you will never see, a kit may be enough. For anything you look at every day, anything that has rusted, cracked or holed, or anything on a coloured surface, it’s worth having it done properly.

What bath resealing costs

Quotes are free and the price is fixed. What we look at:

  • The size and number of damaged areas
  • The type of damage
  • The material
  • Whether we combine several jobs

We charge the same wherever you are, with no extra for Margam. The job itself decides the price: how much damage, what it’s made of and how many items.

How to get a fixed price

Good photos mean an accurate price. Here’s what we find most useful:

  • Your postcode, so we can check dates
  • Any earlier repairs or coatings
  • Good light, ideally daylight, without flash glare
  • Any details about the material

Pricing is simple: snap the damage close up and then the entire item, send them to us with your postcode, and you will get a fixed quote back. Quotes are free and no obligation.

Margam questions

Can you redo someone else’s repair?

What happens after I send photos?

We look at the photos and reply with a fixed price and some dates. If anything’s unclear, we will ask for another photo.

Does someone need to be in?

We need someone to let us in. You don’t need to watch us work.

Is my repair covered?

All our work carries a one-year guarantee. We’ll explain what it covers when we quote.

Do you work for landlords and businesses?

Yes. We work for landlords, agents, builders and businesses as well as homeowners.

Is it OK to have pets in the house?

Keep pets and children away from the work area on the day, so the repair isn’t disturbed while it cures.

Are you a vetted contractor?

We hold CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile accreditations.

Landlord and trade work in Margam

If you manage property in Margam, we will quote for several properties at once. Send photos for each one and we’ll come back with a combined price.

We’re used to working with agents and managing companies. Send the address, pictures and access details.

Looking after it afterwards

After the repair has cured, a few habits help it last:

  • Use the extractor fan
  • Air the room after use
  • Clean the joints with a mild cleaner
  • Dry the seal after bathing

Do not scrape the sealant with anything sharp, and keep shampoo bottles off the joints.

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

The process

Here’s how a visit normally runs: we arrive on time, protect everything around the work area, carry out the work and clear up. Allow around two hours from start to finish. Before leaving, we tell you how long to leave it and what to avoid for the first few days.

  1. The surrounding area is protected and the joints masked.
  2. Old sealant and residue are removed.
  3. The joint is cleaned, treated and dried.
  4. We run a continuous bead of new silicone.
  5. We smooth the bead, remove the tape and leave it to cure.

Getting ready for the visit

  • Let us know which floor the room is on
  • Mention any earlier repairs or resurfacing
  • Clear toiletries, mats and anything else from around the area

Is resealing worth it?

A professional reseal costs little compared with water damage. It’s quick, tidy and protects your home. What it costs depends on how much damage there is and what kind, what it’s made of and how many jobs we combine into one visit. You get a fixed quote from your pictures, so you know the cost before you book.
