What the job involves on each surface
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Each joint is cleaned and primed where needed so the sealant lasts.
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in and baths are filled before sealing.
New build mastic in Boars Hill
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a seal that is letting water through needs doing now. Typical jobs include cracks appearing as a new home settles and sealant work across a run of new homes, on skirting & floors, plot handovers and show homes.
Around Boars Hill, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
There’s a 12-month guarantee on every job, large or small.

The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Boars Hill, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed
- Mention any tricky access

Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Leave it or put it right?
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time. Where a wall is exposed, as many are in small places like Boars Hill, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Every job is quoted individually. Just call 0345 464 0079 or drop us an email with the details, and photos are welcome.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Look at the sealant regularly in the first couple of years
- Report sealant problems to your builder during the snagging period
- Avoid running a DIY bead over the old one
- Get a leaking seal dealt with straight away
Keep photos of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
For landlords and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
