Remedial sealant in Warner's End
The wrong product in the wrong joint fails however neatly it’s applied. Out it comes, and in goes a sealant suited to the job. We’re often asked to deal with torn expansion joints and repeat leaks from the same joint, on expansion joints, botched or over-sealed joints and leaking tray & enclosure joints.
In and around Warner's End, older properties sit alongside newer ones. In older homes, walls and floors can move a little more, so the right flexible sealant matters.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll give you a quote.
How the visit works
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most joints, depending on how much old sealant has to come out.

- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive

Common problems we fix in Warner's End
Even good sealant ages. Mould grows into the silicone, the surface hardens and the bead shrinks, especially in damp, poorly aired rooms. At that point it has to come out.
The problems people generally mention when they call include:
- Gaps opening along the back of the worktop
- Repeat leaks from the same joint
- A second bead peeling off the first
- Products that weren’t meant for the joint
Schools such as Micklem Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
Before booking anyone
- Who does the work, and how experienced they are
- What happens if they find a problem under the old sealant
- Whether they’re fully insured
- What preparation is included
What happens if it’s left?
A joint that has failed twice will fail again unless the cause is dealt with. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. In an older home around Warner's End, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Why us?
- We leave the area clean and tidy
- Homes, businesses and hotels
- White, clear, grey or coloured to suit, where the product allows
- We never seal over old sealant

Bathrooms and kitchens in Warner's End
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings. Warner's End is part of Hemel Hempstead, one of the post-war new towns. Many homes date from the post-war decades, so bathrooms and kitchens may be on their second or third set of sealant. Sealant laid over old sealant never bonds properly, so it all has to come out.
Letting a property close to Hemel Hempstead station? Then a joint that keeps failing is best fixed properly while the property is empty. For an older house near a landmark such as St Alban's Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Never seal over old silicone
- Have loose fittings fixed before resealing
- Run the fan after every shower
- Never fill a movement joint with mortar or grout
Give the new sealant its full cure time: normally around 24 hours, or as long as we advise.
Warning signs: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Any of them means it’s time for remedial work.
Warner's End: your questions answered
I let a flat near Hemel Hempstead station. Can you help?
Yes. We work for landlords and letting agents as well as householders. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Should the sealant in an older Warner's End home be renewed?
Generally, yes, if it’s cracked, shrunk, mouldy or coming away. New sealant will not stick to old, so the old bead has to come out completely first.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
How long does remedial resealing take?
It takes a few hours, depending on how many layers have to come out. We will give you a timescale when we quote.
Where do you work from?
We’re a Crawley-based firm. We work across South East England, London and Scotland.
Is remedial work guaranteed?
Yes, with our 12-month guarantee. If we’ve pointed out another problem, getting it fixed helps the new joint last.
Are you insured?
Yes. We’re fully insured for every job we do.
My shower still leaks after a reseal. Can you sort it?
Yes. Repeat leaks normally come from over-sealing, movement or water getting in elsewhere, and we deal with the cause first.

Shrunken worktop sealant leaves a gap that lets water into the back edge. We strip it, degrease the joint and reseal.
Windows & doors
Some leaks around windows come from the wall or the window itself. We check the joint and tell you if it looks to be something else.
