Bath resealing in Garthmyl without replacing anything
Baths are resealed with water in them, so the joint is at its widest, so the seal doesn’t tear when the bath is first used. We work on wet rooms, basins & vanity units and baths, and the jobs we see most are discoloured, yellow sealant and black mould in the sealant.
Whatever the size of the job, you get the same one-year guarantee in Garthmyl and across Powys.

Work for landlords and builders
Rental properties take more wear, and replacing items every time a tenant leaves is expensive. Repairing between tenants keeps the property presentable for less.
Housing associations and facilities teams use us for planned and reactive repairs in Powys and across the UK. A repair avoids taking out and refitting, which is easier on the people living there.

How it works
A typical visit goes like this: we arrive at the agreed slot, protect everything around the work area, carry out the work and clear up. Allow around two hours from start to finish. Before leaving, we tell you how long to leave it and how to care for it.
- The surrounding area is protected and the joints masked.
- We remove the old sealant and every trace of residue.
- The joint is cleaned, treated and dried.
- Fresh silicone is applied in a continuous bead.
- The bead is smoothed, the tape removed and the seal left to cure.
Before we arrive
- Let us know about parking or access
- Have a window or extractor fan available
- Clear the area around the damage

Garthmyl: your questions answered
Do you hold any accreditations?
We’re accredited with CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile.
What happens if you find more damage?
If we find something the pictures didn’t show, we explain it first. The price only changes if you agree.
Do you cover Garthmyl?
Yes, we do. We send a technician to Garthmyl for every job, and the price is the same as everywhere else.
My seal keeps tearing. Why?
Movement is the usual cause, or it was sealed with the bath empty. We fill the bath before sealing it.
Is there a call-out fee?
Travel is included in the price, and we charge the same wherever you are.
Can you quote from photos?
Yes, almost always. Clear photos let us give you a fixed quote without visiting.
Do you do work for letting agents?
Yes, frequently. We can quote for several properties together and work between tenancies.
Is repairing better than replacing?
Usually, if the item is otherwise sound. A repair avoids removal and making good. We’ll tell you honestly if replacement makes more sense.
Do you need bath resealing in Garthmyl?
A bathroom without good ventilation is hard on sealant: moisture sits on the joints longer, and mould takes hold.
Send us a photo if you notice any of these:
- Silicone coming away from the tiles
- Water getting behind the bath or tray
- Discoloured, yellow sealant
- An untidy old seal
Questions to ask before you book
- How soon you can use it again
- How changes to the job are handled
- Who turns up on the day
- How the room is protected while they work
DIY repairs versus a professional job
What a professional repair adds is preparation, colour matching and finishing. We prepare the area properly, mix the colour on site and polish the finish to match, and the work is guaranteed.
It’s tempting to reach for a kit, but many of the jobs we do start with putting right a DIY repair. Doing it properly first is usually the cheaper route.
Aftercare tips
Nothing complicated is needed:
- Store bottles on a shelf
- Wipe the joints dry after use
- Run the extractor fan during and after showers
- Let steam out after showers
Keep the room well ventilated, and wipe the joints after use so mould struggles to take hold.
Mouldy sealant is more than a cosmetic problem, it’s a sign moisture is sitting in the joint. An early reseal keeps water where it belongs.
What we can’t put right
We would rather lose a job than do one that will not last, so here’s what a repair can’t put right:
- Hollow or loose tiles
- Very wide gaps that need a trim
- Hidden water damage
Not sure? Send photos and we will give you a straight answer before you book.
What we work on
- Kitchen worktops & sinks
- Baths
- Wet rooms
- Basins & vanity units

Prices and what affects them
There’s no area surcharge for Garthmyl. The price reflects:
- Whether we combine several jobs
- How easy the damage is to reach
- What the surface is made of
- Whether old repairs or coatings need taking off
There are no surprise extras on the day. The price we quote from your photos is the price you pay, and if the damage turns out to be different, we discuss it before starting.
Quotes from your photos
A couple of clear pictures is all it takes. It helps if you send:
- A coin or ruler next to the damage for scale
- One sharp close-up of the damage
- Details of any past repairs
- The postcode, so we can plan the visit
You do not need a survey visit. Nearly every job can be priced from photos: send a close-up, a wider shot and your postcode, and we will reply with a fixed quote.
