Remedial sealant in South Harewood, done properly
Remedial work is what we do when sealant has failed or been done badly. New sealant over old, smeared beads, unsuitable products and hidden mould all need stripping out. We work on botched or over-sealed joints, mouldy bath & shower sealant and failed movement joints, and the jobs we see most are beads that never stuck properly and worktop sealant that has shrunk and split.
Being in a small place like South Harewood makes no difference to the job itself: it just means planning the journey and access beforehand. In the bathroom or kitchen, the work is the same as in any town.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

DIY versus a professional finish
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. All the old material has to come out first.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Different surfaces, different methods
Windows & doors
Some leaks around windows come from the wall or the window itself. If the frame joint is not the cause, we will say so.
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. Once it’s all removed, the joint is treated so the new sealant starts clean.
Why act early in South Harewood
Hidden water does the most damage: wet floors, stained ceilings and swollen worktops. Dealing with the joint now is a small job by comparison. Where a wall is exposed, as many are in small places like South Harewood, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

What we do, step by step
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. In a small place like South Harewood, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children

Questions from South Harewood
Can you help a landlord with a rental near Andover station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
Do you cover smaller places like South Harewood?
Yes, South Harewood is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you take off two layers of silicone?
Yes. We remove every layer; over-sealing fails because silicone won’t bond to silicone.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
What if resealing won’t fix my leak?
Then we explain what we’ve found. A plumber or fitter may be needed before any new sealant goes on.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
How long does remedial resealing take?
A little longer than a standard reseal. Most jobs take a few hours, and we confirm the time with your quote.

When to call us in South Harewood
Joints that move need sealant that can stretch. A bath that flexes, a tray that rocks or a building joint that opens and closes will split a rigid or thin bead.
Common reasons people contact us are:
- Repeat leaks from the same joint
- Sealant that came away because the surface wasn’t prepared
- Mould trapped under a layer of silicone
- Floor or wall movement joints that have failed
If you let a flat or house near Andover station, botched sealant from a previous quick fix is easier to strip out between tenants.
