About our remedial sealant in How Wood
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 have to come out. Common call-outs are for gaps opening along the back of the worktop and beads that never stuck properly, on failed movement joints, botched or over-sealed joints and shrunken worktop sealant.
In a smaller place like How Wood, homes are mostly houses and bungalows rather than flats, some older and some much newer. Bathrooms and kitchens here get the same daily wear as anywhere, and the sealant and grout show it first.
All our work comes with our 12-month guarantee.

Honest limits
A few problems are outside what sealant work can do:
- A tray or bath that’s cracked
- Sealant in an older building that needs testing for asbestos first
- A tray or worktop that needs refixing first
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before you book.
What we seal
- Shrunken worktop sealant
- Botched or over-sealed joints
- Expansion joints
- Failed movement joints
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Run the fan after every shower
- Do not point over movement joints
- Report a tray that rocks or a worktop that lifts
- Do not wait for a small gap to become a leak
Leave the new joint to cure fully before it gets wet or moves: usually around 24 hours, or as long as we advise.
If a joint has failed more than once, stop resealing it. Get the cause found first, otherwise the next attempt will fail too.
Remedial sealant in How Wood: local notes
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Managing a site like How Wood Primary and Nursery School? Then washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.

Leave it or put it right?
Mould under a bead can’t be reached by cleaning. The layers have to come out. Homes in smaller places like How Wood can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start.

How it works
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for most joints, depending on how much old sealant has to come out in most cases. For a job in How Wood, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
Before we arrive
- Move anything stored near the joints
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children

Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
My shower still leaks after a reseal. Can you sort it?
Yes. There’s usually a reason: sealant over sealant, movement or another leak, and we deal with the cause first.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint.
Should I try it myself first?
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.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
