Remedial sealant in Andwell, 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 are often asked to deal with leaks that keep coming back after resealing and worktop sealant that has shrunk and split, on botched or over-sealed joints, mouldy bath & shower sealant and failed movement joints.
Homes around Andwell are mostly houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. Sealant and grout wear out here just as they do anywhere: old material cut out, joints cleaned and a fresh finish laid.
Your job is guaranteed for a year, as with all our work.

Common questions in Andwell
Is Andwell in your area for remedial sealant?
Yes. We work across London and the South East, and Andwell is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
I let a flat near Hook station. Can you help?
Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
Do you fix expansion and movement joints?
Yes. The depth is set with backing so the sealant only bonds to the two sides.
How long does the work take?
That depends on how many layers there are and how many joints. You will have a timescale before any work begins.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Are you insured?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
When something else is needed
We will always be straight with you, so here’s what new sealant won’t do:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Water damage behind tiles that needs a tiler
If in doubt, ring 0345 464 0079 or email us and we will say what we think before you book.

What we’re called out for in Andwell
A lot of failed joints have been sealed over rather than replaced. New silicone can’t stick to the old bead, so the new layer peels, and damp and mould settle between them.
Keep an eye out for any of the following:
- Floor or wall movement joints that have failed
- Sealant applied over old sealant that has lifted
- A shower that leaks however often it’s resealed
- Wide, uneven beads that look worse than the old ones
If you live in an older home near St Swithun's church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
What to look for in a quote
- How long the guarantee is
- What the cure time is
- Whether the sealant suits the joint
- What happens if the job turns out different
DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

Quotes for remedial sealant in Andwell
Jobs vary more than people expect. What affects the quote:
- The product the joint needs
- The size of the job
- How easy the joints are to reach
- Working hours on commercial sites
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and agree the price before starting.
What we need to know
When you call or email, it’s useful to know:
- Any previous sealing or DIY work
- Access, such as stairs, a lift or height
- Where the job is, and your postcode
- How many joints, rooms or windows are involved
We don’t publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or drop us an email.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Don’t wait for a small gap to become a leak
- Don’t point over movement joints
- Air the bathroom so the sealant can dry
- Keep an eye on the ceiling below the bathroom
If we’ve found a cause, such as a loose tray or a leaking waste, get it fixed, because the new sealant cannot hold back a problem underneath.
If a joint has failed more than once, stop resealing it. Have someone find out why, otherwise the next attempt will fail too.
What we do, step by step
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours, depending on how many layers have to come out, depending on the size of the job.

- Next, any mould is treated and the joint dried.
- We use the right backing and sealant for any joint that moves.
