New build mastic in Little Horsted
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly instead of bonding to the dust. If you have cracked caulk along new skirting and leaking shower tray seals in a new home, we can help.
Older homes in small places like Little Horsted often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Should I go to my builder first?

What information do you need?
A short description and the location, plus pictures if you have them. If we need more, we will ask.
Why does sealant fail so quickly in new builds?
Lots of new homes see sealant crack early, because the house is drying and settling. Poor preparation at handover adds to it.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.

How the visit works
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take a few hours in a single home. For a village or hamlet like Little Horsted, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you’re given the cure time.
How to prepare
- On commercial sites, let us know about site rules
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before

Advice
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Follow the cure time we give you
- Wipe joints with warm soapy water
- Keep pictures and emails about snagging items
- Don’t seal over failed sealant yourself
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and the new finishes intact.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
