About our remedial sealant in Portsmouth Point
Getting old sealant out properly is slow, careful work. We cut out every layer, clear the residue and degrease the surfaces, taking care not to scratch the surfaces around it. New sealant only bonds to a clean, dry joint. If you’re dealing with sealant applied over old sealant that has lifted and products that weren’t meant for the joint, we can put it right, on expansion joints, shrunken worktop sealant and leaking tray & enclosure joints alike.
Around Portsmouth Point, you will mostly find houses and bungalows, some older and some much newer. Bathrooms and kitchens here get the same daily wear as anywhere, and the sealant and grout show it first.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

DIY versus a professional finish
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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
When to call us in Portsmouth Point
A lot of failed joints have been sealed over rather than replaced. New silicone can’t stick to the old bead, so the new layer peels, and damp and mould settle between them.
Look out for any of the following:
- Smears and lumps from a botched reseal
- Over-sealed joints coming away
- Leaks that keep coming back after resealing
- Beads that never stuck properly
For an older house near a landmark such as Portsmouth Garrison church, walls and floors in older homes can move, and sealant and grout show it first.

Your questions about remedial sealant in Portsmouth Point
Do you take on hotel work around Portsmouth Point?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Do you cover smaller places like Portsmouth Point?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you reseal a split movement joint?
Yes. The depth is set with backing so the sealant only bonds to the two sides.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
Can you fix a reseal that hasn’t worked?
Yes, normally. First we check whether the leak is the sealant at all, then the joints are stripped and resealed.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you when we finish.
How long does the work take?
A little longer than a standard reseal. For most joints, it’s a few hours, and we confirm the time with your quote.
What if the leak isn’t the sealant?
We’ll tell you. If it’s a cracked tray, a failed valve or a leaking waste, resealing won’t fix it, so we won’t pretend it will.
How it works
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. It normally takes a few hours for most joints, depending on how much old sealant has to come out. In a smaller place like Portsmouth Point, 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.
- 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.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you’re told about anything else we found.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Clear the area around the work
- Let us know if you’ve seen damp or leaks
