New build mastic for homes and businesses in Martin Mill
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. Common call-outs are for untidy sealant flagged on a snagging list and kitchen sealant that has pulled off the wall, across skirting & floors, bathrooms & en suites and show homes.
Older homes in small places like Martin Mill 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’ll sort it.

The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most snagging lists, longer for a run of plots and we leave things clean and tidy. For a village or hamlet like Martin Mill, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided 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.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.

Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we are using and why.
DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Keeping the joints in good condition
So the new joints stay in good condition:
- Act quickly if a seal starts to leak
- Clean sealant with mild detergent, not abrasives
- Resist patching a failed seal with a tube from the DIY shop
- Look at the sealant regularly in the first couple of years
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day before water reaches them.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
When something else is needed
In fairness, there are a few things sealant will not fix:
- Deciding who is responsible under a builder’s warranty
- Movement caused by a poorly fitted tray or bath
- Structural cracks in walls or ceilings
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before you book.

External mastic around new windows and doors is sometimes rushed or missed. It’s resealed with an exterior sealant suited to the frame and wall.
