Remedial sealant in Sidlesham
Removing failed sealant is the hardest part of the job. We cut out every layer, clear the residue and degrease the surfaces, without scratching tiles, trays or frames. Only then can new sealant bond. We work on botched or over-sealed joints, mouldy bath & shower sealant and expansion joints, and the jobs we see most are wide, uneven beads that look worse than the old ones and dark patches showing through the sealant.
Somewhere as small as Sidlesham, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.
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.

Looking after it afterwards
Looking after new joints is easy:
- Don’t point over movement joints
- Act on a lifting corner right away
- Report a tray that rocks or a worktop that lifts
- Do not add new sealant on top of old
Go easy on the new sealant: a mild cleaner and a soft cloth, with no blades or scourers.
A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.
What we do, step by step
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes a few hours, depending on how many layers have to come out. Somewhere as small as Sidlesham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at how the sealant has failed and check for movement or a leak path.
- All the old sealant comes out, including any layers underneath.
- Next, any mould is treated and the joint dried.
- Moving joints get backing and a flexible sealant to suit.
- Finally we finish the joint and talk you through what we found.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints
- Tell us about access, such as stairs, a lift or high-level joints

What else we do in Sidlesham
What happens if it’s left?
Mould under a bead can’t be reached by cleaning. The layers have to come out. Where a wall is exposed, as many are in small places like Sidlesham, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why book with us
- Approved under the ARBOMaster scheme
- Anti-fungal silicone where joints get wet
- Domestic, commercial and hotel work
- A sealant colour to suit the surroundings

Remedial sealant around Sidlesham
Sidlesham is within about 1 mile of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
For an older house near a landmark such as St Mary Our Lady Sidlesham, older homes can move a little, which is hard on rigid grout and tired sealant. If you look after a building such as Sidlesham Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Rented homes near Chichester station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.

FAQs for Sidlesham
Do you work in hotels near Sidlesham?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
Do you work for landlords with property near Chichester station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Where do you work from?
We work from Crawley. We cover Sidlesham and the rest of West Sussex, along with the rest of our area.
Can you match the sealant colour?
Yes. White, clear and grey are common, and other colours are available for many products, and we’ll agree it with you first.
How long does remedial resealing take?
It takes a few hours, depending on how many layers have to come out. You will know the timing when we quote.
Can you strip sealant from an acrylic tray safely?
Yes. We cut and lift the old sealant with tools suited to the surface, and the residue is cleaned away. We point out any damage that’s already there.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Can failed expansion joints be resealed?
Yes. Where mortar or filler has been used instead of sealant, it’s removed where it can be, then the joint is sealed properly.
How the job changes by surface
Over-sealed & botched joints
Previous removal attempts can leave scratches or gouges. We take care not to make it worse, and point out any existing damage.
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is normally part of the cause. We will reseal and tell you if extraction looks to be the issue.
DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Landlords, agents and businesses in Sidlesham
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured for the work.
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
