Remedial sealant for homes and businesses in Hook
With more than 20 years’ experience, our applicators have seen most of the ways sealant can fail. We’re ARBOMaster approved and fully insured, and every remedial job comes with a 12-month guarantee. Common call-outs are for black mould underneath the bead and kitchen joints letting water behind the worktop, across shrunken worktop sealant, leaking tray & enclosure joints and failed movement joints.
In a smaller place like Hook, homes are mostly houses and bungalows rather than flats, from older cottages to newer builds. Sealant and grout wear out here just as they do in a big town.
You’re covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

Why act early in Hook
Adding more sealant is the usual quick fix, and it rarely works. It doesn’t grip the old layer, so the leak carries on and there’s now more to remove. In a smaller place like Hook, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

Do you need remedial sealant in Hook?
Joint depth matters. A bead bonded on three sides, or laid too thick, can’t flex, so it tears when the joint moves. Backing rod or bond-breaker tape prevents it.
Look out for these signs:
- Kitchen joints letting water behind the worktop
- Floor or wall movement joints that have failed
- Wide, uneven beads that look worse than the old ones
- Beads that never stuck properly
Rented homes near Hook station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
What your quote should include
- Whether the sealant suits the joint
- What happens if the job turns out different
- Whether you can choose the colour
- How long the guarantee is

Smeared or badly matched mastic can be cut out and redone neatly, matched to the frame colour.
What affects the cost of remedial sealant
Every job gets its own quote. This is what makes a difference:

- How much old sealant there is and how hard it is to remove
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.

Hook: your questions answered
I let a flat near Hook station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you work in hotels near Hook?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Do you work in Hook?
Yes. We’re based in Crawley and work across South East England, London and Scotland, Hook included.
Can failed expansion joints be resealed?
Yes. Where mortar or filler has been used instead of sealant, it’s removed where it can be, and reseal with a flexible product.
How much does remedial sealant cost in Hook?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or drop us an email with a short description of the job.
Can you take off two layers of silicone?
Yes. Both layers come out; over-sealing fails because silicone won’t bond to silicone.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Do you offer different sealant colours?
In most cases you can choose. We will explain which colours are available.
Honest limits
To be straight with you, there are a few things sealant won’t fix:
- Tiles that have come away from the wall
- A cracked shower tray or bath (that needs repair or replacing)
- Plumbing leaks behind walls or under trays
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.

Bathrooms and kitchens in Hook
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings. There are hotels and other places to stay in and around Hook. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
Schools such as Hook Junior School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes. For an older house near a landmark such as St John the Evangelist, older homes can move a little, which is hard on rigid grout and tired sealant.

How the visit works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours for a typical bath or shower, longer where several layers have been applied from start to finish. A visit to Hook is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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.
How to prepare
- Tell us if parking is tricky
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can
