Bath resealing for Newtown homes

Bath resealing in Newtown without replacing anything

A good reseal is all about preparation: old silicone removed, mould treated, the joint cleaned and dried. Then the fresh sealant goes on, in a neat, continuous bead. Our repair technicians work on wet rooms, baths and kitchen worktops & sinks, and the jobs we see most are silicone smeared on tiles and black spots in the silicone.

Every job is backed for twelve months. If something goes wrong with the work, we come back.

For landlords and businesses

Landlords, letting agents and housing providers in Newtown use us as well as householders. A repair between tenants keeps the property empty for less time, and it costs much less than replacing.

Rented homes see more wear and tear, and replacing things at every changeover adds up. A repair between tenancies is a cheaper way to keep the property in good order.

Why it’s worth resealing in Newtown

Compared with repairing water damage, resealing is cheap. It’s a quick job that protects your walls and floors. There are no surprise extras on the day. What we quote from your pictures is what you pay, unless the damage turns out to be different, in which case we talk to you first.

What you get with us

  • CHAS and Constructionline accredited
  • Dust sheets down, tidy finish
  • Nothing taken out or refitted
  • Most jobs done in one visit

See our pricing.

What we can’t put right

It helps to know what we can’t do too:

  • Hollow or loose tiles
  • Rotten walls or floors behind the bath
  • Very wide gaps that need a trim

If in doubt, send photos and we’ll say what we think before booking.

What we work on

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

DIY kit or professional repair?

A kit can be fine for a tiny mark out of sight. 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.

Kits are cheap and easy to find, but many of the jobs we do start with putting right a DIY repair. Doing it properly first is normally the cheaper route.

What your bath or shower is made of matters

Shower trays

Trays are sealed with weight on them, so the joint is at its widest.

Baths

We fill the bath before sealing, to open the joint fully.

What affects the price in Newtown

Quotes are free and the price is fixed. What we take into account:

  • Where the damage is and how we get to it
  • Unusual colours or finishes
  • What the surface is made of
  • How many areas need work

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.

Getting a price from photos

You can normally get a fixed price without us visiting. To make it quick:

  • Any details about the material
  • Daylight if possible, and no flash reflection
  • One sharp close-up of the damage
  • Where you are, by postcode

You don’t 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.

What we do, step by step

Arrival times are agreed in advance, so you know when to expect us. Once we’re there, the work takes about two hours for a bath in most cases. We leave the room clean and you’ll know when it can be used.

  1. We cut out and remove all of the old sealant.
  2. We clean the joint and treat any mould.
  3. We dry the joint thoroughly.
  4. We fill a bath with water before sealing so the gap is at its widest.
  5. We apply new mould-resistant silicone and tool it to a neat finish, including around the taps.

Preparing for the visit

  • Clear the area around the damage
  • Have a window or extractor fan available
  • Mention if the room is upstairs or in a flat

Getting a price

FAQs for Newtown

How soon can you come?

We will give you dates with your quote. Tell us if you need it done quickly.

How long will it take?

A bath or shower normally takes a couple of hours. Leave it to cure before use.

Why does my sealant keep going mouldy?

Damp is the cause. Run the fan, dry the joints and the new seal stays cleaner for longer.

Do the materials smell?

There may be a mild smell during the work that clears as it cures.

Do you work in Newtown?

We do. We send a technician to Newtown for every job, and the price is the same as everywhere else.

Is there a call-out fee?

We don’t add a call-out fee. The fixed quote covers the visit and the work.

Can you redo someone else’s repair?

Most of the time. Tell us what was done before and we will plan for it.

What happens next?

You’ll get a fixed quote back. You are under no obligation.
