Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
About our remedial sealant in Purbrook
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. We’re often asked to deal with sealant applied over old sealant that has lifted and black mould underneath the bead, across botched or over-sealed joints, leaking tray & enclosure joints and failed movement joints.
Homes around Purbrook have been extended and refitted over the decades. Sealant run over the top of an old bead is a common cause of leaks and mould, so we take every joint back to clean before anything new goes in.
A 12-month guarantee comes as standard.

Purbrook homes and their sealant
Purbrook is within about 2 miles of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, and sealant and grout that work that hard wear out sooner. Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you look after a building such as Purbrook Junior School, we reseal washrooms and kitchens in schools and businesses as well as homes. If you live in an older home near Church of St John, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. For landlords with property near Bedhampton station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
Purbrook is about 2 miles west of Havant, in Hampshire. From the centre of Purbrook to the outskirts, remedial sealant is available for homes and businesses alike. Purbrook is one of 683 places in Hampshire we cover.

Aftercare tips
To keep the joints looking good and working properly:
- Have loose fittings fixed before resealing
- Keep the room well ventilated
- Keep an eye on the ceiling below the bathroom
- Find out why the sealant failed first
If the joint ever needs renewing, have it cut out, not sealed over. New silicone does not bond to old, so the old bead should always come out first.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into whatever is behind or below. Sorting it early limits the damage.
Honest limits
A few problems are outside what sealant work can do:
- Cracks in the fitting rather than the joint
- Sealant in an older building that needs testing for asbestos first
- Movement from fittings that aren’t supported

Why it’s worth doing now in Purbrook
Ripping out a bathroom is not normally needed. If the bath, tray and tiles are sound, remedial resealing generally puts it right. If they’re not, we will tell you. In Purbrook, as anywhere, most leaks start as a small gap in a joint, and they’re far easier to fix early.
The cost depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before any work starts, so you know where you stand.

The process
You do not need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for most joints, depending on how much old sealant has to come out in most cases. Parking in a town like Purbrook is normally straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you’re told about anything else we found.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit

Questions from Purbrook
Is there a guarantee on remedial sealant in Purbrook?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Do you cover Purbrook for remedial sealant?
Yes. Our work covers London and the South East, and Purbrook is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.
Can you reseal a split movement joint?
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 long does the work take?
A little longer than a standard reseal. Most jobs take a few hours, and we confirm the time with your quote.
Can old silicone be taken off without scratching the tiles?
Yes. The old bead is cut and lifted with tools that suit the surface, and the residue is cleaned away. Any existing damage is pointed out before any work starts.
Where are you based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or email us.
Can you take off two layers of silicone?
Yes. Stripping layered sealant takes longer than a normal reseal, but it’s what makes the new bead last.
