Why act early in Catslip
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times. Older cottages and farmhouses around Catslip can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first.
Why book with us
- We leave the area clean and tidy
- Rated 4.9 stars on Google
- Quality sealants from Arbo and Everbuild
- A 12-month guarantee on all work
New build mastic in Catslip, done properly
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. We work on bathrooms & en suites, plot handovers and kitchens, and people most often call us about cracked sealant around new window and door frames and sealant applied over dusty or wet surfaces.
Older homes in small places like Catslip often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
You get a 12-month guarantee, the same in Catslip as everywhere else we work.

The process
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes a few hours in a single home, depending on how much there is to do. Somewhere like Catslip needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Each joint is checked for movement before any work starts.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Before we arrive
- Mention if the joints have been sealed before
- Let us know about parking restrictions
- Mention any sign-in or site rules at work premises

What new build mastic looks like in Catslip
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
How we quote for new build mastic
Some jobs are bigger than they look, and some smaller. The main factors:

Before you ask for a quote, have a think about:
- Where the property is
