New build mastic in Crockham Hill, done properly
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. Typical jobs include frame joints opening as the plaster dries and cracks appearing as a new home settles, across plot handovers, kitchens and bathrooms & en suites.
In a village or hamlet like Crockham Hill, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.

What else we do in Crockham Hill
What we’re called out for in Crockham Hill
Sealant applied onto damp surfaces does not bond well. Site programmes don’t always leave time for joints to dry before the sealant goes on.
Keep an eye out for any of the following:
- Cracked caulk along new skirting
- Internal frame sealant that has split
- Joints pulling apart as timber shrinks
- Leaking shower tray seals in a new home
In and around Crockham Hill, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Leave it or put it right?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it cannot bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. Where a wall is exposed, as many are in small places like Crockham Hill, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.

Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Report sealant problems to your builder during the snagging period
- Wait for the cure time before using a resealed shower
- Do not seal over failed sealant yourself
- Don’t wait for the house to settle if water is getting through
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you.
Surface by surface
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it painted or coloured to suit.
Kitchens
As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. A fresh flexible bead closes them.
