- Thick, messy sealant smeared over tiles

What sealant work cannot fix
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A tray or worktop that needs refixing first
- A leaking trap, valve or supply pipe
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before booking.
Surfaces we seal
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
- Failed movement joints
- Shrunken worktop sealant
- Expansion joints
- Botched or over-sealed joints
About our remedial sealant in Walton on the Hill
A joint that keeps failing generally has a reason. Movement, the wrong product or a leak from somewhere else will beat any new bead. Finding that cause comes before any new sealant. We work on expansion joints, failed movement joints and mouldy bath & shower sealant, and the jobs we see most are gaps opening along the back of the worktop and sealant applied over old sealant that has lifted.
In a village or hamlet like Walton on the Hill, homes are often older cottages and farmhouses alongside a few newer houses. Movement in older walls and floors tends to show first as cracked grout or split sealant.
A one-year guarantee comes as standard.

What we do, step by step
We keep the work tidy and contained to the joints we are treating, so you can get on with your day. The job generally takes a few hours for a typical bath or shower, longer where several layers have been applied. Somewhere as small as Walton on the Hill, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you are told about anything else we found.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- For indoor joints, keep the area dry beforehand if you can
- Let us know about parking restrictions

Advice
What the job involves on each surface
Worktops & kitchens
Kitchen joints hold grease and residue, so we spend extra time cleaning before resealing.
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is usually part of the cause. We will reseal and tell you if extraction looks to be the issue.
Remedial sealant around Walton on the Hill
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you live in an older home near Church of St Peter, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. For landlords with property near Tadworth station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Common problems we fix in Walton on the Hill
Even good sealant ages. Over the years it shrinks, hardens and gets colonised by mould, especially in damp, poorly aired rooms. Then the only fix is removal and a new bead.
Look out for any of the following:
- Beads that never stuck properly
- A shower that leaks however often it’s resealed
- Products that weren’t meant for the joint
- Movement joints that have split or pulled away
If you look after a building such as Walton-on-the-Hill Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Other services in Walton on the Hill
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Why it’s worth doing now in Walton on the Hill
Another bead over the top won’t fix a failed joint. It doesn’t grip the old layer, so the leak carries on and there’s now more to remove. In a small place like Walton on the Hill, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
