How we handle new build mastic in Rabbit's Cross
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. We work on show homes, skirting & floors and bathrooms & en suites, and people most often call us about gaps behind new kitchen upstands and messy sealant that spoils new finishes.
For a small place like Rabbit's Cross, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
Your job is guaranteed for a year, as with all our work.

Aftercare tips
Aftercare is simple:
- Do not seal over failed sealant yourself
- Do not wait for the house to settle if water is getting through
- Raise failed sealant with the developer while you’re covered
- Look at the sealant regularly in the first couple of years
Keep photos of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.

Other services in Rabbit's Cross
Do you need new build mastic in Rabbit's Cross?
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint.
Any of these means the joints need attention:
- Sealant work across a run of new homes
- Messy sealant that spoils new finishes
- Leaking shower tray seals in a new home
- Worktop and upstand sealant coming away
Around Rabbit's Cross, as everywhere, new build mastic is only as good as the preparation behind it.

Rabbit's Cross: your questions answered
Do you work for landlords with property near Staplehurst station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
Will you come out to Rabbit's Cross?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you.
Do you take on second-fix sealing for builders?
Yes. We take on second-fix sealant work across new plots. We clean and prime joints properly to keep callbacks down.
How long does new build mastic take?
Most jobs take a few hours in a single home, including preparation and clearing up. Your quote will say how long we expect yours to take.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Rabbit's Cross.
Should I wait before resealing?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
What happens on the day
At the end, we look at the finished work together. The visit itself usually takes anything from a few hours to several days, depending on the number of plots, depending on the amount of work.
