Different materials, different repairs

Baths

We fill the bath before sealing, so the joint is at its widest.

Sinks and worktops

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

Resealing in Knighton: why it matters

A reseal is one of the cheapest bathroom jobs there is and protects the walls and floor. Failed sealant can lead to water damage that is much more expensive. The price depends on how much damage there is and what kind, what it’s made of and how many items we do on one visit. You get a fixed quote from your photos, so you know the cost before you book.

What you get with us

  • We will tell you if it’s not worth repairing
  • Dust sheets down, tidy finish
  • One price list for the entire UK
  • Nothing taken out or refitted

Your questions about bath resealing in Knighton

Will it make a mess?

No. The work area is masked and covered, and we take our waste away with us.

Can you reseal over the old silicone?

No, we never seal over old silicone. It’s removed, cleaned off and the joint dried first.

Is repairing better than replacing?

Generally, yes. A repair skips the removal, fitting and redecorating. We will be honest if it’s not worth it.

Can you quote from photos?

Nearly always. We only ask to see it in person if the pictures cannot show what we need.

How much does bath resealing cost in Knighton?

Because every job differs, we price from pictures. You will get a fixed figure before booking.

Can tenants book a repair?

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

Does someone need to be in?

Someone needs to let us in and show us the job. You do not need to watch us work.

What happens next?

We review the photos and send a fixed quote with dates.

Keeping it looking good

A little care keeps the finish looking good. Our advice:

  • Dry the seal after bathing
  • Open a window after bathing
  • Reseal when black spots will not clean off
  • Give the seal a regular clean

Let it cure fully before using the bath or shower, normally about a day.

Damp below or loose tiles need checking quickly. It may be more than a reseal, and we will say if you need a builder or plumber.

When a repair is not the answer

We’ll always be straight with you, so here’s what a repair won’t do:

  • Tiles that move, until they’re refixed
  • A bath or tray that moves, until its support is fixed
  • Gaps so wide they need filling or trims before sealing

If in doubt, send photos and we will say what we think.

What we work on

  • Wet rooms
  • Baths
  • Kitchen worktops & sinks

Can I fix it myself?

DIY kits are sold for most surfaces, and they can tidy up a tiny mark. Where they fall down is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler frequently lifts.

If you’re set on a kit, follow its instructions closely, and give it the full curing time. If it does not work out, we can still repair it properly.

What we are called out for in Knighton

Even good sealant eventually discolours particularly in a well-used bathroom. Steam, soap and movement all take their toll.

Customers generally contact us about:

  • Silicone smeared on tiles
  • Missing sealant behind the taps
  • Gaps in the seal
  • Mould you can’t clean out

Questions to ask before you book

  • Whether cleaning and preparation are in the price
  • How long the guarantee is and what it covers
  • If travel is included in the price
  • A fixed quote, and whether VAT is included

Choosing a repair company

What affects the price in Knighton

Prices are worked out job by job, from your photos. What matters most is:

  • What the surface is made of
  • Access to the area
  • How much damage there is
  • The type of damage

Every job is a little different, so we price each one individually. What’s damaged, how badly and how easy it is to reach all play a part, and combining jobs on one visit brings the cost down.

How to get a fixed price

Before you send photos, a few simple things make all the difference:

  • A clear, close picture of the problem area
  • Your postcode, so we can check dates
  • Daylight if possible, and no flash reflection
  • One picture of the entire bath or shower

Email us photos of the damage and a wider shot of the whole item, and tell us you’re in Knighton, and we will come back with a fixed quote.

How it works

From the moment we arrive, the aim is to do the job without disturbing the rest of your home. We mask off everything nearby, the job takes around two hours, depending on what we find, and we finish by cleaning up and talking you through the result.

  1. The surrounding area is protected and the joints masked.
  2. We remove the old sealant and every trace of residue.
  3. We clean, treat and dry the joint.
  4. We run a continuous bead of new silicone.
  5. The bead is smoothed, the tape removed and the seal left to cure.

How to prepare

  • Tell us about any previous repairs or coatings
  • Mention any parking restrictions or tricky access
  • Ensure the area is dry
