Remedial sealant for homes and businesses in Totteridge
Not every leak is a sealant leak. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. If that is what we find, we will tell you rather than reseal something that will not fix it. Common call-outs are for torn expansion joints and dark patches showing through the sealant, on leaking tray & enclosure joints, shrunken worktop sealant and botched or over-sealed joints.
Homes around Totteridge range from older cottages to more recent houses. Older homes can move a little with the seasons, which is hard on tired sealant and rigid grout.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

Leave it or put it right?
Remedial work takes longer than a straight reseal, but not by much: it takes a few hours, depending on how many layers have to come out. Compared with chasing the same leak every few months, it’s time well spent. In a smaller place like Totteridge, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

What the job involves on each surface
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. We remove the failed sealant, fit backing and reseal with a low-modulus product.
Mouldy bath & shower sealant
Black mould inside the bead will not scrub out. The sealant is cut out completely, the joint treated with a mould remover and dried before anti-fungal sanitary silicone goes in.
Signs you need remedial sealant in Totteridge
Even good sealant ages. Mould grows into the silicone, the surface hardens and the bead shrinks. Then the only fix is removal and a new bead.
The most common problems we see are:
- A second bead peeling off the first
- Decorators’ caulk around a bath or shower
- Black mould underneath the bead
- Floor or wall movement joints that have failed
Schools such as Highcrest Academy are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What happens on the day
There is not much for you to do on the day. Point us to the joints and we will get on with it. 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 Totteridge is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- 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.
How to prepare
- Mention any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks
- Let us know about earlier repairs to the joints

Advice
Bathrooms and kitchens in Totteridge
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings. There are hotels and other places to stay in and around Totteridge. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
If you live in an older home near St Andrew's Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. For landlords with property near High Wycombe station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Get the cause of a repeat leak found before resealing
- Deal with small splits early
- Use a soft cloth, not a scourer, on silicone
- Look for stains below bathrooms now and then
Do not let anyone seal over it later. Over-sealing is how many remedial jobs start.
Movement joints that have split let water into the structure, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.
