About our new build mastic in Fairbourne Heath
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you’re still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. We work on plot handovers, bathrooms & en suites and show homes, and people most often call us about sealant that never bonded to the surface and leaking shower tray seals in a new home.
For a small place like Fairbourne Heath, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
You are covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or email us.

Why deal with it now?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times to plan around. Around Fairbourne Heath, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why Fairbourne Heath customers choose us
- Any old sealant cut out fully, not covered over
- Homes, businesses and hotels
- A 12-month guarantee on all work
- 4.9 on Google from 180+ five-star reviews

Aftercare tips
Good habits help new joints last longer. Our tips:
- Put sealant faults on your snagging list early
- Watch for new gaps as the house dries out
- Follow the cure time we give you
- Keep pictures and emails about snagging items
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers to help keep mould away.
Early snagging is easier snagging. Left alone, a small crack can become a leak in a busy bathroom.

Other services in Fairbourne Heath
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Questions from Fairbourne Heath
Do you cover smaller places like Fairbourne Heath?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Harrietsham station?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or email us with the details for a clear quote.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Fairbourne Heath and the rest of Kent.
How long does the job take?
As a guide, most jobs take a few hours in a single home. Bigger jobs take longer, and we’ll say how long yours will take.
Is it worth resealing while the house is still settling?
If the seal has failed and water is getting in, do it now. Small gaps that are just cosmetic can be resealed once movement has slowed.
What sealant work cannot fix
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Your warranty claim itself, which is between you and the builder
- Leaks from pipes, valves or wastes, which need a plumber
- Baths and trays that move too much for sealant to cope with
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly.
Surfaces we seal
- Kitchens
- Bathrooms & en suites
- Show homes
