New build mastic in Horton Kirby, done properly
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. We work on plot handovers, bathrooms & en suites and skirting & floors, and the jobs we see most are shower seals failing in the first year or two and cracked sealant around new window and door frames.
Older homes in small places like Horton Kirby often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Whatever the size of the job, you get the same 12-month guarantee.

How it works
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take a few hours in a single home. In a small place like Horton Kirby, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you’re given the cure time.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints

Advice
Common problems we fix in Horton Kirby
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
Look out for these signs:
- Joints pulling apart as timber shrinks
- Frame joints opening as the plaster dries
- Worktop and upstand sealant coming away
- Sealant work across a run of new homes
Around Horton Kirby, as everywhere, new build mastic is only as good as the preparation behind it.

Common questions in Horton Kirby
Do you cover Horton Kirby for new build mastic?
Yes. Our work covers London and the South East, and Horton Kirby is part of that. Just ring 0345 464 0079 or email us with a few details of the job.
Do you work for landlords with property near Farningham Road station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
How much does new build mastic cost in Horton Kirby?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

What else we do in Horton Kirby
Leave it or put it right?
DIY kits do not solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Where a wall is exposed, as many are in small places like Horton Kirby, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.
