Your questions about bath resealing in Graig-y-Rhacca

Why does the silicone keep cracking?

Movement is the usual cause. We seal baths full of water.

What if the damage is worse than the photos show?

It’s rare, but if it happens we talk to you first. You decide whether to go ahead.

Can pets and children be at home?

Just keep them out of the work area. We’ll let you know when it’s safe to use again.

How long before I can shower?

Generally after around 24 hours. We confirm before we leave.

What areas do you cover?

We work UK-wide, so Graig-y-Rhacca is covered. Our prices are the same everywhere.

Can new silicone go over old?

All the old sealant comes out. Fresh silicone does not stick to old.

Do you hold any accreditations?

We’re accredited with CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile.

Will you leave a mess?

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

Why it’s worth resealing in Graig-y-Rhacca

A professional reseal costs little compared with water damage. It’s quick, tidy and protects your home. A few things move the price: the amount of damage, the material, access to the area, and how many jobs we do in one trip. Photos let us give you a fixed figure.

Why us?

  • Honest advice, even when it means no job
  • Most jobs done in one visit
  • Work done at your home or business
  • Every repair guaranteed for a year

Landlord and trade work in Graig-y-Rhacca

For developers and builders, we fix damage before handover, saving last-minute replacements. We can visit several plots in one trip to keep costs down.

Hotels, guest houses and holiday lets cannot afford rooms out of action for long, so we keep visits short and tidy. We will fit around changeovers where we can.

When we’d advise against a repair

We won’t take on work that won’t last, so here’s what a repair cannot put right:

  • Gaps too big for silicone alone
  • A flexing bath
  • Hidden water damage

If in doubt, send pictures and we’ll say what we think.

What we work on

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

How we price bath resealing

Every quote is fixed and free. What we take into account:

  • The colour and finish to match
  • Where the damage is and how we get to it
  • Any earlier repairs that need removing first
  • Whether we combine several jobs

Every job is a little different, so we price each one individually. The size and type of damage, the material and access all play a part, and combining jobs on one visit brings the cost down.

Getting a price from photos

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

  • A clear, close picture of the problem area
  • A wider photo showing the whole bath or shower
  • A coin or ruler next to the damage for scale
  • Daylight if possible, and no flash reflection

We price from photos so you do not have to wait in for a survey. Send them through the quote form, or call 0345 017 0787 if you’d rather talk it through, and you will get a fixed figure back.

What your bath or shower is made of matters

Shower trays

Trays are sealed with weight on them, for the same reason.

Sinks and worktops

Basins, vanity units and kitchen worktops are resealed too, once the joint is completely dry.

Looking after it afterwards

Simple care helps the repair last. Our advice:

  • Let steam out after showers
  • Reseal at the first sign of lifting
  • Keep bottles off the joints
  • Clean the sealant gently and regularly

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. Gaps or lifting edges mean it needs doing.

How the visit works

When we visit, we arrive at the time we have agreed, cover the area with dust sheets and masking, and set to work. The job generally takes a couple of hours. We clean up when we’re 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. We treat mould and dry the joint thoroughly.
  4. The bath is filled with water, or weight put on the tray.
  5. New mould-resistant silicone is applied and tooled neatly.

Preparing for the visit

  • Tell us if there are stairs or a lift
  • Let us know about parking or access
  • Plan for the room to be out of bounds to pets and children
