Problem with your new-build sealant joints in Heyshott Green? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.

- Gaps opening as the house dries out and settles
- Sealant that never bonded to the surface
New build mastic in Heyshott Green
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. If you have sealant that never bonded to the surface and kitchen sealant that has pulled off the wall, we can put it right.
In a village or hamlet like Heyshott Green, 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.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Leave it or put it right?
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. Where a wall is exposed, as many are in small places like Heyshott Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.

DIY sealant or a professional job?
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.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Different surfaces, different methods
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.
Plot handovers
Developers can send the plot schedule and specification and we will quote. We seal bathrooms, kitchens, frames and floors.
Landlords, agents and businesses in Heyshott Green
We work for letting agents and landlords as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

How long does new build mastic take?

Where is Mr Mastic based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Do you work through snagging lists?
Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before we start.
Why does sealant fail so quickly in new builds?
There are generally two causes: movement as the house dries and settles, and sealant laid onto dust without primer. Cutting it out and resealing properly fixes both.
What we can’t put right
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- Cracked trays, tiles or worktops
- Plumbing faults behind the sealant
- Settlement cracks that need a surveyor
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer.

The process
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 normally takes anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Heyshott Green, the journey is planned in advance: 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.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Clear items away from the joints we’re working on
- Try not to wet indoor joints just before the visit
