DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
About our remedial sealant in Baldock
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint fails however neatly it’s applied. We take it out and use a sealant made for that joint. We work on mouldy bath & shower sealant, shrunken worktop sealant and failed movement joints, and people most often call us about gaps opening along the back of the worktop and torn expansion joints.
Even in a smaller place like Baldock, bathrooms and kitchens see heavy daily use. Whether it’s a cottage bathroom or a newer en suite, the approach is the same: old sealant or grout cut out, joints cleaned and dried, and a fresh finish laid.
Our work is backed for twelve months, in Baldock and everywhere else we cover.

Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used.
Where do you work from?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Don’t wait for a small gap to become a leak
- Use a soft cloth, not a scourer, on silicone
- Keep movement joints clear of mortar and paint
- Never seal over old silicone
Watch the joint over the first few weeks, particularly where the original failure was caused by movement. If anything changes, just ring 0345 464 0079 or email us.
Warning signs: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Each one is worth getting looked at.
When it is not the sealant
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Cracks in the fitting rather than the joint
- Movement from fittings that aren’t supported
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.
Surfaces we seal
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints

Why it’s worth doing now in Baldock
Spraying mould remover on a sealed-over joint does not reach what’s underneath. The layers have to come out. In an older home around Baldock, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Doing several joints on one visit normally makes better use of the time than several visits. You’ll get one clear quote for the whole job.

Remedial sealant around Baldock
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Letting a property close to Baldock station? Then a joint that keeps failing is best fixed properly while the property is empty. Homes close to Church of St. Mary the Virgin include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them. Managing a site like Hartsfield Junior Mixed and Infant School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

What happens on the day
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours, depending on how many layers have to come out. A visit to Baldock 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.
- We start by checking the joint for movement, leaks and the reason it failed.
- All the old sealant comes out, including any layers underneath.
- Next, any mould is treated and the joint dried.
- We use the right backing and sealant for any joint that moves.
- The new joint is tooled neatly and we explain anything else we found.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Tell us if parking is tricky
- Clear items away from the joints we are working on

How the job changes by surface
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so we spend extra time cleaning before resealing.
Movement & expansion joints
A movement joint must be able to stretch. We remove the failed sealant, fit backing and reseal with a low-modulus product.
