Bath resealing in Corntwn without replacing anything

A good reseal is all about preparation: old silicone removed, mould treated, the joint cleaned and dried. Only then does the new sealant go on, in a neat, continuous bead. We regularly repair kitchen worktops & sinks, baths and shower trays & enclosures, and the jobs we see most are gaps by the taps and water getting behind the bath or tray.

Every job is backed for twelve months, and the guarantee is the same wherever you live. We return to put right any problem with the work.

What happens on the day

Here’s how a visit typically runs: we arrive at the agreed slot, sheet and mask the area around the job, carry out the work and tidy away. Allow around two hours from start to finish. Before we go, we will explain when it can be used and how to look after it.

  1. We protect the area and mask the joint lines.
  2. Old sealant and residue are removed.
  3. We clean, treat and dry the joint.
  4. Fresh silicone is applied in a continuous bead.
  5. We smooth the bead, remove the tape and leave it to cure.

Before we arrive

  • Keep children and pets away from the room on the day
  • Mention any earlier repairs or resurfacing
  • Clear the area around the damage

Is resealing worth it?

Resealing is a small job. Leaving split or mouldy sealant can let water reach the walls and floor, and that damage costs much more to fix. Most people are surprised how affordable a repair is, especially compared with replacing and refitting. Photos let us give you the exact figure.

Honest limits

In fairness, there are a few things a repair will not fix:

  • Movement in the bath or tray
  • Gaps so wide they need filling or trims before sealing
  • Hollow or loose tiles

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

Materials we work on in Corntwn

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

What your bath or shower is made of matters

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, so the joint is at its widest.

Can I fix it myself?

The difference between a kit and a professional repair is mostly in the preparation and colour. We prepare the area properly, mix the colour on site and polish the finish to match, and the work is guaranteed.

If you do try a kit, read the instructions carefully, and do not use it until it has fully cured. If it fails, we can still put it right.

How to care for the repair

How the surface is treated afterwards matters:

  • Reseal when black spots won’t clean off
  • Clean the joints with a mild cleaner
  • Use the extractor fan
  • Wipe the joints dry after use

Keep the room well ventilated, and dry the joints after bathing so mould struggles to take hold.

If you notice damp, stains on the ceiling below or loose tiles, act quickly. There may be more going on, and we’ll say if you need a builder or plumber.

Landlord and trade work in Corntwn

We’re used to working with agents and managing companies. Just send pictures, the address and how to get access and we will arrange it.

Hotels, guest houses and holiday lets need rooms back in use quickly, so most of our work is done in a single visit. We can work around your bookings.

Do you need bath resealing in Corntwn?

In time, even good sealant discolours, especially in a busy family bathroom. Steam, soap and movement all take their toll.

It’s worth getting a quote if you see:

  • Sealant that’s split or lifting
  • Discoloured, yellow sealant
  • Gaps by the taps
  • Mould you cannot clean out

What your quote should include

  • How the room is protected while they work
  • Whether the colour is mixed to match
  • If travel is included in the price
  • Is the price fixed, and does it include VAT?

Questions from Corntwn

Is a repair better than a new one?

Normally, if the item is otherwise sound. Repairing avoids the cost and disruption of replacing. We will tell you honestly if replacement makes more sense.

Is it messy?

Very little mess: we sheet and mask everything nearby, and we leave the room clean.

Can new silicone go over old?

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

What happens next?

We look at the pictures and reply with a fixed quote and some dates. If we need another angle, we’ll ask.

Is there any odour?

It depends on the job, but often a little. Open windows and an extractor fan help.

How quickly can you book me in?

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

What if the damage is worse than the pictures show?

We stop, show you and agree any change before carrying on. You will not be charged for anything you haven’t agreed.

When can I use the bath after resealing?

Normally about a day later. We confirm before we leave.
