About our remedial sealant in East Harting
Remedial jobs in East Harting normally fall into a few patterns: over-sealed joints, hidden mould, repeat leaks and split movement joints. We strip each one back and start from scratch. We work on shrunken worktop sealant, failed movement joints and leaking tray & enclosure joints, and common reasons people get in touch are black mould underneath the bead and floor or wall movement joints that have failed.
Being in a small place like East Harting makes no difference to the job itself: it just means planning the journey and access beforehand. Once we’re there, the bathroom or kitchen gets the same care as anywhere else.
There’s a 12-month guarantee on every job.

How the visit works
You do not need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes a few hours for a typical bath or shower, longer where several layers have been applied in most cases. Somewhere like East Harting needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we work out whether the problem is the sealant, movement or a leak.
- 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.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Tell us if parking is tricky
- Tell us about any previous sealing or DIY attempts

What affects the cost of remedial sealant
For a quick quote, just ask. What matters most is:
- The product the joint needs
- Any mould that needs treating
- How many areas need sealing
- Whether old sealant or filler has to be cut out
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking
- How we’d reach the joints
- A few pictures by email, if you can
There’s no standard price list. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or send us an email.
Why deal with it now?
Another bead over the top will not fix a failed joint. It doesn’t grip the old layer, leaving the leak in place and one more layer to cut out later. Around East Harting, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

East Harting questions
Do you work for landlords with property near Petersfield station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Do you cover smaller places like East Harting?
Yes. East Harting is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you strip sealant from an acrylic tray safely?
Yes. The old bead is cut and lifted with tools that suit the surface, then clean off the residue. We point out any damage that is already there.
Do you fix expansion and movement joints?
Yes. Backing sets the depth and stops the sealant sticking to the back, which lets it stretch.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
Can you match the sealant colour?
Yes. Sealants come in white, clear, grey and other colours, and we’ll agree it with you first.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or email us.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
What we can’t put right
To be straight with you, some problems need a different trade:
- A cracked shower tray or bath (that needs repair or replacing)
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Tiles that have come away from the wall
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before booking.
Surfaces we seal
- Leaking tray & enclosure joints
- Botched or over-sealed joints
- Mouldy bath & shower sealant
- Expansion joints
- Failed movement joints
- Shrunken worktop sealant
When to call us in East Harting
Joints that move need sealant that can stretch. A bath that flexes, a tray that rocks or a building joint that opens and closes will split a rigid or thin bead.
Look out for any of the following:
- Thick, messy sealant smeared over tiles
- Sealant applied over old sealant that has lifted
- Beads that never stuck properly
- Repeat leaks from the same joint
Schools such as Harting CofE Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
What to look for in a quote
- Are they insured?
- What the cure time is
- Which sealant they’ll use, and why
- Whether VAT is included
Work for landlords, hotels and businesses
We work for letting agents and landlords as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Bathrooms and kitchens in East Harting
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
If you let a flat or house near Petersfield station, a joint that keeps failing is best fixed properly while the property is empty. For an older house near a landmark such as The Parish Church of St Mary & St Gabriel, walls and floors in older homes can move, and sealant and grout show it first.

Looking after it afterwards
A little care helps the new joints last. We recommend:
- Look for stains below bathrooms now and then
- Don’t wait for a small gap to become a leak
- Do not point over movement joints
- Report a tray that rocks or a worktop that lifts
Don’t let anyone seal over it later. New silicone doesn’t bond to old.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.
