What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we are using and why.

That depends on the sealant used, so follow the cure time we give you.
Remedial sealant in Heronsgate, done properly
Remedial jobs in Heronsgate generally fall into a few patterns: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. Each is stripped back and done again properly. We work on shrunken worktop sealant, mouldy bath & shower sealant and leaking tray & enclosure joints, and the jobs we see most are thick, messy sealant smeared over tiles and sealant that came away because the surface wasn’t prepared.
In a village or hamlet like Heronsgate, homes are often older cottages and farmhouses alongside a few newer houses. Movement in older walls and floors tends to show first as cracked grout or split sealant.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What remedial sealant looks like in Heronsgate
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
Managing a site like Chorleywood Primary School? Then washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. In the older streets around St John, older homes can move a little, which is hard on rigid grout and tired sealant. Rented homes near Chorleywood station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.

Advice
Why deal with it now?
A joint that has failed twice will fail again unless the cause is dealt with. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. Older cottages and farmhouses around Heronsgate can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What you get with us
- Old sealant always removed completely
- 4.9 on Google from 180+ five-star reviews
- A sealant colour to suit the surroundings
- Anti-fungal silicone where joints get wet
Take a look at our cost guide or what customers say.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Look for stains below bathrooms now and then
- Run the fan after every shower
- Find out why the sealant failed first
- Use a soft cloth, not a scourer, on silicone
Leave the new joint to cure fully before it gets wet or moves: generally around 24 hours, or as long as we advise.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

How the job changes by surface
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed with a low-modulus product.
Windows & doors
A frame that keeps leaking may not be the mastic. If the frame joint isn’t the cause, we will say so.
