Remedial sealant in Gilbert Street, done properly
Getting old sealant out properly is slow, careful work. Every layer is cut out, the residue cleaned off and the joint degreased, taking care not to scratch the surfaces around it. New sealant only bonds to a clean, dry joint. We’re often asked to deal with dark patches showing through the sealant and smears and lumps from a botched reseal, across failed movement joints, mouldy bath & shower sealant and botched or over-sealed joints.
For a small place like Gilbert Street, remedial sealant is planned like any other job: the journey and access are simply agreed in advance. In the bathroom or kitchen, the work is the same as in any town.
There’s a 12-month guarantee on every job.

What happens on the day
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes a few hours, depending on how many layers have to come out, depending on the amount of work. In a small place like Gilbert Street, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Preparing for the visit

- Tell us about any previous sealing or DIY attempts

Advice
Gilbert Street: your questions answered
Is Gilbert Street in your area for remedial sealant?
Yes. We work across London and the South East, and Gilbert Street is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
What guarantee comes with remedial sealant in Gilbert Street?
All our work, in Gilbert Street and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Do you work for letting agents?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels across Hampshire.
Can you remove sealant that is been put over old sealant?
Yes. Each layer is cut out and the residue cleaned off, before resealing with a single bead.
What if resealing will not fix my leak?
We will tell you. If it’s a cracked tray, a failed valve or a leaking waste, resealing will not fix it, so we will not pretend it will.
How do I get a quote for remedial sealant in Gilbert Street?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before work begins.
Do the sealants smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Do you need remedial sealant in Gilbert Street?
One of the commonest remedial jobs is sealant on top of sealant. Silicone doesn’t bond to silicone, so the new layer peels, and damp and mould settle between them.
These are the problems we are asked about most:
- Kitchen joints letting water behind the worktop
- Floor or wall movement joints that have failed
- Dark patches showing through the sealant
- Leaks that keep coming back after resealing
Homes close to Church of St Peter include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.

What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Tiles that have come away from the wall
- A tray or bath that is cracked
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.

Quotes for remedial sealant in Gilbert Street
Every job gets its own quote. These are the things that affect it:
- The type of sealant required
- The amount of work
- Any mould that needs treating
- Access and height
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Ask us for a quote and we will explain what it covers.
Asking for a quote
When you call or email, it’s useful to know:
- Access, such as stairs, a lift or height
- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or send us an email.
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
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 fails, we can still redo it.
Landlord and commercial work in Gilbert Street
For anyone letting property in or around Gilbert Street, jobs at different addresses can be quoted together. Send us the addresses and the work at each, and photos by email help.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
Why it’s worth doing now in Gilbert Street
Adding more sealant is the usual quick fix, and it rarely works. It can’t bond to what’s underneath, so the leak carries on and there’s now more to remove. Where a wall is exposed, as many are in small places like Gilbert Street, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
