Honest limits
New sealant cannot fix everything, and we’ll tell you before work begins. Sealant won’t put right:
- Broken tiles or a split tray
- Your warranty claim itself, which is between you and the builder
- Leaking fittings rather than failed sealant
If you are not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.

New build mastic in Farnborough, done properly
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over using the right product for each joint. We are often asked to deal with sealant applied over dusty or wet surfaces and gaps behind new kitchen upstands, on show homes, bathrooms & en suites and kitchens.
Older homes in small places like Farnborough often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Each job carries a 12-month guarantee.

How it works
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Farnborough, 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.
- Each joint is checked for movement before work begins.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can

Signs you need new build mastic in Farnborough
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open.
Keep an eye out for any of the following:
- Shower seals failing in the first year or two
- Untidy sealant flagged on a snagging list
- Sealant applied over dusty or wet surfaces
- Cracked caulk along new skirting
Around Farnborough, as everywhere, new build mastic is only as good as the preparation behind it.
Before you book anyone
- How the colour is chosen
- How much experience the applicator has
- What guarantee comes with the work
- How the surfaces are prepared before sealing
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Photograph failed sealant before it’s redone
- Ventilate bathrooms well, especially in the first year
- Do not wait for the house to settle if water is getting through
- Keep water off fresh sealant until it has cured
Follow the cure time we give you before the area gets wet. Most silicones need around a day.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left.
Leave it or put it right?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Around Farnborough, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What you get with us
- Sanitary silicone with an anti-fungal additive in wet areas
- Approved under the ARBOMaster scheme
