We are fully insured ARBOMaster approved applicators, and remedial work carries our 12-month guarantee. We work on shrunken worktop sealant, leaking tray & enclosure joints and failed movement joints, and the jobs we see most are leaks that keep coming back after resealing and gaps opening along the back of the worktop.
Homes around Denvilles range from older cottages to more recent houses. In older homes, walls and floors can move a little more, so the right flexible sealant matters.

Do you need remedial sealant in Denvilles?
Products get mixed up: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. None of them last.
The problems people generally mention when they call are:
- Wide, uneven beads that look worse than the old ones
- Sealant that came away because the surface wasn’t prepared
- Torn expansion joints
- Mould trapped under a layer of silicone
Schools such as Warblington School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
Questions to ask before booking
- How the joint is cleaned and prepared
- What happens if they find a problem under the old sealant
- What the cure time is
- The length of the guarantee
How it works
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a few hours for most joints, depending on how much old sealant has to come out, including the tidy-up. For a job in Denvilles, 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.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
How to prepare
- Clear the area around the work
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks

Advice
Landlord and commercial work in Denvilles
We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured.
We work for landlords and agents as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
Different surfaces, different methods
Windows & doors
Wrong-coloured or messy mastic can be replaced for appearance too, in a colour that suits the frame.
Mouldy bath & shower sealant
Mould that has grown into silicone doesn’t clean out for good. All of it comes out, and the joint is treated and dried before anti-fungal sanitary silicone goes in.
When something else is needed
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Older mastics that may need an asbestos check before removal
- A bath, tray or worktop that moves until it’s properly fixed
- Leaks from a shower valve, waste or pipework (a plumber’s job)
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before booking.
Surfaces we seal
- Shrunken worktop sealant
- Leaking tray & enclosure joints
- Expansion joints
- Botched or over-sealed joints
- Mouldy bath & shower sealant
- Failed movement joints
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Have loose fittings fixed before resealing
- Get the cause of a repeat leak found before resealing
- Don’t wait for a small gap to become a leak
- Never fill a movement joint with mortar or grout
Watch the joint over the first few weeks, especially if movement was the problem. If anything changes, just phone 0345 464 0079 or email us.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into floors, walls or ceilings. Sorting it early limits the damage.
Your questions about remedial sealant in Denvilles
Can you help a landlord with a rental near Warblington station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Is Denvilles within the area you cover?
Yes. Denvilles is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Is it messy?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we’re done.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How long should I leave it?
Cure times vary by product and the temperature. Before we leave, we’ll tell you the cure time.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Can you do several jobs on one visit?
Of course. Doing several areas at once is usually more efficient.

Remedial sealant in Denvilles: local notes
Denvilles is close to the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, and sealant and grout that work that hard wear out sooner. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
For an older house near a landmark such as St Thomas à Becket Church, older homes can move a little, which is hard on rigid grout and tired sealant. Letting a property close to Warblington station? Then botched sealant from a previous quick fix is easier to strip out between tenants.

Near you in Denvilles
Locally, jobs take us to homes and businesses close to Six Bells pub, St Albans Church and Fairfield Infant School. Denvilles has its own railway station: Warblington station. A little further out are Warblington Castle (0.7 miles south) and Havant War Memorial Hospital (1 mile west). Green spaces nearby include Brook Meadow (Emsworth).
Should I try it myself first?
If you are 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.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
