Remedial sealant in Downend, done properly
Removing failed sealant is the hardest part of the job. We cut out every layer, clear the residue and degrease the surfaces, taking care not to scratch the surfaces around it. Only then can new sealant bond. We work on mouldy bath & shower sealant, expansion joints and leaking tray & enclosure joints, and people most often call us about dark patches showing through the sealant and sealant peeling off a dusty or damp surface.
In a village or hamlet like Downend, 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.
Big or small, you get the same one-year guarantee.

Work for landlords, hotels and businesses
If you manage several properties in or around Downend, several properties can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
How the visit works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself generally takes a few hours for a typical bath or shower, longer where several layers have been applied, depending on how much there is to do. In a small place like Downend, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky
- Clear items away from the joints we’re working on
Getting a quote
Every job is quoted individually, so the first step is telling us about yours. Simply ring 0345 464 0079 or email us and describe the job and send photos if you have them.
Advice
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Cracks in the fitting rather than the joint
- Water damage behind tiles that needs a tiler
If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer.
Surfaces we seal
- Failed movement joints
- Expansion joints
- Mouldy bath & shower sealant
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Shrunken worktop sealant
How the job changes by surface
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. Once it’s all removed, the joint is treated so the new sealant starts clean.
Leaking trays & enclosures
When failed joints are the cause, they’re all cut out and renewed, including the screen profile and tray edges.
Common problems we fix in Downend
Silicone only bonds to surfaces that are clean and dry. Soap film, dust, damp or old residue stop it gripping, so it starts lifting sooner than it should.
Keep an eye out for these signs:
- Caulk or the wrong sealant used in a wet area
- Smears and lumps from a botched reseal
- Leaks that keep coming back after resealing
- Sealant peeling off a dusty or damp surface
Managing a site like Medina College? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
Questions to ask before booking
- How the colour is chosen
- Is VAT in the price?
- Which sealant they’ll use, and why
- Whether they’re fully insured
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Why act early in Downend
A failed seal rarely means a new bathroom. When the fittings are sound, stripping and resealing the joints is often enough. Where something else has failed, you’ll hear it from us. In a small place like Downend, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will go through it with you.
Why Downend customers choose us
- Over 20 years’ experience
- An ARBOMaster approved applicator
- Old sealant always removed completely
- White, clear, grey or another colour, product permitting

What else we do in Downend
Remedial sealant in Downend: local notes
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
Rented homes near Smallbrook Junction station change hands often, and a joint that keeps failing is best fixed properly while the property is empty. If you live in an older home near St. George's Church, walls and floors in older homes can move, and sealant and grout show it first.
