Remedial sealant & repairs in Great Bookham, Surrey
We cover Great Bookham for removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly.
- Products that weren’t meant for the joint
- Leaks that keep coming back after resealing
- Gaps opening along the back of the worktop
The process
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours, depending on how many layers have to come out. Parking around Great Bookham is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- 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.
- We use the right backing and sealant for any joint that moves.
- Finally we finish the joint and talk you through what we found.
Preparing for the visit
- On commercial sites, let us know about site rules
- Move anything stored near the joints
- Let us know about earlier repairs to the joints

Advice
Remedial sealant in Great Bookham, done properly
Not every leak is a sealant leak. A cracked tray, a failed shower valve or a leaking waste can look just the same. When the fault is elsewhere, we say so instead of resealing for the sake of it. We work on botched or over-sealed joints, failed movement joints and mouldy bath & shower sealant, and the jobs we see most are torn expansion joints and over-sealed joints coming away.
In and around Great Bookham, older properties sit alongside newer ones. In older homes, walls and floors can move a little more, so the right flexible sealant matters.
Our work is backed for twelve months.

Schools such as The Dawnay School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes. Letting a property close to Bookham station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Do you need remedial sealant in Great Bookham?
Water from somewhere else can ruin a good seal. A slow leak behind the tiles soaks the joint from the back, and the sealant lifts or goes mouldy from underneath.
These are the problems we are asked about most:
- Thick, messy sealant smeared over tiles
- Caulk or the wrong sealant used in a wet area
- Sealant applied over old sealant that has lifted
- Sealant that came away because the surface wasn’t prepared
In the older streets around Church of St Nicolas, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
What to look for in a quote
- How the joint is cleaned and prepared
- What happens if they find a problem under the old sealant
- Whether they seal over old material or remove it
- Whether the sealant suits the joint
Surface by surface
Windows & doors
Some leaks around windows come from the wall or the window itself. We check the joint and tell you if it looks to be something else.
Movement & expansion joints
A movement joint must be able to stretch. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed with a low-modulus product.
What happens if it’s left?
Mould under a bead cannot be reached by cleaning. The layers have to come out. In a smaller place like Great Bookham, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Report a tray that rocks or a worktop that lifts
- Do not wait for a small gap to become a leak
- Clean sealant with mild products only
- Find out why the sealant failed first
Go easy on the new sealant: no scraping, scouring pads or harsh chemicals.
Warning signs: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Each one is worth getting looked at.
