How we handle remedial sealant in Pangbourne
In Pangbourne, as anywhere, remedial jobs tend to look alike: over-sealed joints, hidden mould, repeat leaks and split movement joints. Each is stripped back and done again properly. We work on expansion joints, shrunken worktop sealant and leaking tray & enclosure joints, and people most often call us about decorators’ caulk around a bath or shower and sealant applied over old sealant that has lifted.
Around Pangbourne, you will mostly find houses and bungalows, some older and some much newer. Sealant and grout wear out here just as they do in a big town.
Every job comes with our 12-month guarantee.

Why it’s worth doing now in Pangbourne
Spraying mould remover on a sealed-over joint doesn’t reach what’s underneath. Removal is the only way to get at it, and the joint treated and dried before resealing. Around Pangbourne, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Pangbourne homes and their sealant
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings. There are hotels and other places to stay in and around Pangbourne. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
In the older streets around Church of St James the Less, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Rented homes near Pangbourne station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Air the bathroom so the sealant can dry
- Get the cause of a repeat leak found before resealing
- Act on a lifting corner right away
- Check ceilings under showers for marks
Go easy on the new sealant: no scraping, scouring pads or harsh chemicals.
Movement joints that have split let water into the structure, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.
When to call us in Pangbourne
Water from somewhere else can ruin a good seal. A slow leak behind the tiles soaks the joint from the back, so the silicone goes mouldy or lets go.
Common reasons people contact us are:
- Worktop sealant that has shrunk and split
- Wide, uneven beads that look worse than the old ones
- Over-sealed joints coming away
- Mould trapped under a layer of silicone
Schools such as Pangbourne Primary School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.
Before you book anyone
- When the joint can take water or movement
- Is the old sealant removed completely?
- Who turns up on the day
- What happens if they find a problem under the old sealant
DIY sealant or a professional job?
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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Surface by surface
Mouldy bath & shower sealant
Black mould inside the bead won’t scrub out. All of it comes out, and the joint is treated and dried ahead of a new anti-fungal bead.
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed with a low-modulus product.
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
The process
The work is kept neat and contained to the joints we’re treating. Expect the work to take a few hours, depending on how many layers have to come out, and we tell you how long to leave it before we go. A visit to Pangbourne is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we find out how and where the joint has failed.
- All the old sealant comes out, including any layers underneath.
- The joint is cleaned, treated for mould and left to dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- Finally we finish the joint and talk you through what we found.
Preparing for the visit
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts
