New build mastic in Soberton Heath, done properly
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation. We work on kitchens, skirting & floors and show homes, and common reasons people get in touch are sealant applied over dusty or wet surfaces and cracked caulk along new skirting.
Somewhere as small as Soberton Heath, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
Our work is backed for twelve months.

Do you work through snagging lists?
Yes. Send the list and a few photos of the sealant items, and we will quote. We will tell you if anything on it isn’t a sealant job.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or drop us an email.
Why does sealant fail so quickly in new builds?
It’s common, and there are normally two reasons: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
Can you reseal over the builder’s sealant?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before any work starts.
Where is Mr Mastic based?
Our base is Crawley. Our area covers South East England, London and Scotland.
DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What happens if it’s left?
A quick bead over the top of the old sealant can look fine at first, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. Around Soberton Heath, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Clean sealant with mild detergent, not abrasives
- Watch for new gaps as the house dries out
- Get a leaking seal dealt with straight away
- Put sealant faults on your snagging list early
Keep pictures of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak in a busy bathroom.
