Bath resealing at your home in Bangor

A fresh seal protects your bathroom. Failed sealant lets water get where it shouldn’t, and a new seal stops it. Whether it’s unsealed corners and gaps in the seal, we can generally put it right, whatever the material.

Materials and what they mean for the repair

Sinks and worktops

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

Shower trays

We put weight on a tray before sealing it, for the same reason.

Can I fix it myself?

We understand the appeal of fixing it yourself. The risk is that a kit repair hides the damage for a while, then fails, and the old filler has to come out before a proper repair.

You can buy a DIY kit for most repairs, 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 frequently lifts.

Why reseal now?

Resealing costs very little, and it protects everything around the bath. Failed sealant can lead to water damage that is much more expensive. A repair typically costs much less than people expect, particularly next to the cost of replacement. Photos let us give you the exact figure.

Why Bangor customers choose us

  • One price list for the whole UK
  • Most jobs done in one visit
  • Honest advice, even when it means no job
  • A fixed quote before you book

Take a look at our prices page.

Keeping it looking good

Most damage we see is avoidable. These habits help:

  • Ventilate the bathroom well
  • Air the room after use
  • Store bottles on a shelf
  • Reseal at the first sign of lifting

Run the extractor fan, dry the joints after bathing, and clean them regularly with a mild cleaner to slow mould growth.

Don’t wait until water gets behind the bath. Split or lifting sealant is a sign it’s time.

How it works

On the day itself, there is little for you to do. Show us the job, point us to the room, and we’ll take it from there. Most visits take a couple of hours, including clearing up.

  1. We protect the area and mask the joint lines.
  2. We remove the old sealant and every trace of residue.
  3. The joint is cleaned, treated and dried.
  4. We run a continuous bead of new silicone.
  5. The bead is smoothed, the tape removed and the seal left to cure.

Preparing for the visit

  • Move bottles, mats and clutter away from the area
  • Tell us if there are stairs or a lift
  • Have somewhere for us to park nearby if possible

Getting a price

No survey visit is needed: we price from photos. Send them through the quote form, or call 0345 017 0787 if you’d rather talk it through.

Advice

How we price bath resealing

We give every job a fixed price from photos. This is what makes a difference:

  • Doing more than one item at once
  • Whether old repairs or coatings need taking off
  • The material
  • The colour and finish to match

Set against the cost of replacement, repairing usually costs far less, because nothing has to be taken out, refitted or made good. Your fixed quote shows exactly what’s included.

Send photos for a quote

Almost every job we do is priced from pictures. This is what to send:

  • Whether it’s been repaired or coated before
  • Daylight if possible, and no flash reflection
  • A close-up of the damage, in focus
  • What it’s made of, if you know

You do not need a survey visit. Photos are enough for us to price nearly every job: we need a close-up, a wider picture and your postcode, and we’ll come back to you with a fixed figure.

Signs you need bath resealing in Bangor

Joints split if the bath or tray moves, frequently because it was sealed with the bath empty.

Send us a photo if you notice any of these:

  • Discoloured, yellow sealant
  • Black mould in the sealant
  • Missing sealant behind the taps
  • Gaps in the seal

Before you book anyone

  • What protection goes down before work starts
  • Aftercare advice
  • Whether the colour is mixed to match
  • Is the price fixed, and does it include VAT?

Yes, we often do. Removing the old work can add time, and that is in the quote.

Can tenants book a repair?

We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.

What do you need from me?

How much does bath resealing cost in Bangor?

Is it messy?

We protect the room with dust sheets and masking first, and tidy up before we leave.
