Remedial sealant in Lawrence Hill, done properly
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint fails however neatly it’s applied. We take it out and use a sealant made for that joint. We work on expansion joints, failed movement joints and shrunken worktop sealant, and people most often call us about beads that never stuck properly and sealant applied over old sealant that has lifted.
Even in a smaller place like Lawrence Hill, bathrooms and kitchens see heavy daily use. Whether it’s a cottage bathroom or a newer en suite, the approach is the same: old sealant or grout cut out, joints cleaned and dried, and a fresh finish laid.
Every job is covered by a 12-month guarantee.

Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Common problems we fix in Lawrence Hill
Sealant needs a clean, dry surface with no grease on it. Residue, moisture or dust left in the joint weaken the bond, and the joint starts to come away early.
Look out for any of the following:
- Worktop sealant that has shrunk and split
- Movement joints that have split or pulled away
- Dark patches showing through the sealant
- Caulk or the wrong sealant used in a wet area
In the older streets around Holy Trinity Church, older homes can move a little, which is hard on rigid grout and tired sealant.
Questions to ask before you book
- What preparation is included
- Who turns up on the day
- The length of the guarantee
- Whether they’re fully insured
How we quote for remedial sealant
Some jobs are bigger than they look, and some smaller. The main factors:
- Any mould that needs treating
- The product the joint needs
- Working hours on commercial sites
- The number of rooms or windows
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What we need to know
When you contact us, it’s useful to know:
- Any access issues, like height or stairs
- Where the job is, and your postcode
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we will explain what’s involved.
Remedial sealant in Lawrence Hill: local notes
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. Bracknell, which Lawrence Hill is part of, is one of England’s post-war new towns. With many homes dating from the post-war decades, plenty of bathrooms have been resealed or refitted more than once. New sealant won’t stick to old, so the old layers have to come out first.
If you let a flat or house near Bracknell station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. Schools such as Warfield Church of England Primary School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

Leave it or put it right?
Mould under a bead cannot be reached by cleaning. Removal is the only way to get at it, and the joint treated and dried before resealing. In an older home around Lawrence Hill, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will go through it with you.

Different surfaces, different methods
Windows & doors
Frames resealed over the top end up with hard, layered mastic. We remove it all and clean back to sound surfaces.
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so cleaning takes longer than in a bathroom before resealing.
Lawrence Hill questions
I let a flat near Bracknell station. Can you help?
Yes. We work for landlords and agents as well as householders. You can phone 0345 464 0079 or email us with the details for a clear quote.
Is Lawrence Hill within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Does remedial work come with a guarantee?
Yes. Every job comes with our 12-month guarantee.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area.
Where are you based?
Our base is Crawley. We work across South East England, London and Scotland.
What should I tell you?
A short description and the location. If we need more, we’ll ask.
What if resealing won’t fix my leak?
That’s why we look for the cause first. If we find the leak is elsewhere, we tell you before going further.
Can you remove old sealant without damaging the bath?
Yes. The old bead is cut and lifted with tools that suit the surface, then clean off the residue. Any existing damage is pointed out before any work starts.
When something else is needed
We will not take on work that will not last, so here’s what sealant cannot put right:
- Sealant in an older building that needs testing for asbestos first
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- A cracked shower tray or bath (that needs repair or replacing)
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.
Surfaces we seal
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant
- Expansion joints
- Shrunken worktop sealant
- Failed movement joints
How the visit works
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a typical bath or shower, longer where several layers have been applied. In a smaller place like Lawrence Hill, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- 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
- Let us know about earlier repairs to the joints
- Mention any tricky access
- Plan for the work area to be out of bounds to pets and children
