How we handle new build mastic in East Worldham
Across East Worldham, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method doesn’t change: remove, clean, prime where needed, then a neat new bead. We work on windows & doors, kitchens and skirting & floors, and people most often call us about joints pulling apart as timber shrinks and cracked sealant around new window and door frames.
In a village or hamlet like East Worldham, 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.
There’s a 12-month guarantee on every job, large or small.

Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Different surfaces, different methods
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant in a matching colour.
How it works
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours for most snagging lists, longer for a run of plots. In a small place like East Worldham, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked for movement before we start.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Before we arrive
- For business premises, tell us about site rules or sign-in

Common problems we fix in East Worldham
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly.
Any of these means the joints need attention:
- Smeared, uneven beads picked up at snagging
- Leaking shower tray seals in a new home
- Kitchen sealant that has pulled off the wall
- Skirting joints opening in the first winter
If you’ve bought a new home near Alton station, the sealant around baths, showers and frames is worth checking in the first year or two.

Common questions in East Worldham
Will you come out to East Worldham?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Alton station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners. You can phone 0345 464 0079 or email us with the details for a clear quote.
How much does new build mastic cost in East Worldham?
Every job is different, so each one gets its own quote. For a quick quote, ring 0345 464 0079 or send us an email and let us know what needs doing and where.
Will you just run a new bead over the existing one?
No. We always remove the existing bead, the joint cleaned and primed where needed, before resealing.
When is the best time to reseal in a new build?
It depends on whether water is getting through. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
Can you work from my snagging list?
Yes. Photos of each sealant item help us quote. Items that need a plumber, tiler or the builder are flagged.
Can you match the sealant colour to my new kitchen or bathroom?
It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We will agree it with you first.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover East Worldham.
Why act early in East Worldham
Small cosmetic gaps can wait for the house to settle, but water getting through can’t. If you’re unsure which you have, call 0345 464 0079 or email us with photos and we will tell you. Older cottages and farmhouses around East Worldham can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the amount of work, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
Why book with us
- Colour agreed with you before we start
- Full insurance on every job
- Approved under the ARBOMaster scheme
- More than 20 years in sealant work
