About our new build mastic in Catmore
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. We work on show homes, plot handovers and windows & doors, and people most often call us about kitchen sealant that has pulled off the wall and frame joints opening as the plaster dries.
Around Catmore, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
You are covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or send us an email.

Why it’s worth doing now in Catmore
Resealing everything on a snagging list in one visit is generally simpler than chasing joints one at a time. You get one visit and one clear quote. Older cottages and farmhouses around Catmore can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or send us an email for an honest opinion and a quote.

What we’re called out for in Catmore
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart.
The problems people normally mention when they call are:
- Leaking shower tray seals in a new home
- Worktop and upstand sealant coming away
- Messy sealant that spoils new finishes
- Beads laid onto grit and dust from the build
For jobs in and around Catmore, choosing the right material for each joint is as important as a tidy finish.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Avoid running a DIY bead over the old one
- Do not wait for the house to settle if water is getting through
- Ventilate bathrooms well, especially in the first year
- Keep photos and emails about snagging items
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers.
Early snagging is easier snagging. Left alone, a small crack can become a leak in a busy bathroom.

The process
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. For a village or hamlet like Catmore, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- 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.
How to prepare
- Tell us if parking is tricky
- On commercial sites, let us know about site rules
- Keep children and pets away from the work area
