New build mastic for homes and businesses in Flishinghurst
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 rather than sitting on a layer of grit. If you have leaking shower tray seals in a new home and worktop and upstand sealant coming away, we can help.
Older homes in small places like Flishinghurst often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

Different surfaces, different methods
Kitchens
Sink joints are wet all the time. We use a sealant suited to kitchens.
Show homes
Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.
What sealant work can’t fix
A few problems are outside what sealant work can do:
- Disputes or warranty claims with your builder
- Leaks from pipes, valves or wastes, which need a plumber
- Cracked trays, tiles or worktops
If in doubt, ring 0345 464 0079 or email us and we will say what we think.

Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Put sealant faults on your snagging list early
- Wipe joints with warm soapy water
- Resist patching a failed seal with a tube from the DIY shop
- Get a leaking seal dealt with right away
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it as they wear the bead.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
Common problems we fix in Flishinghurst
A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart, and sealant that can’t keep up splits.
Most people get in touch when they notice one of these:
- Messy sealant that spoils new finishes
- New-build shower sealant that has already split
- Internal frame sealant that has split
- Plot mastic for developers ahead of handover
If you’ve bought a new home near Marden station, the sealant around baths, showers and frames is worth checking in the first year or two.

Flishinghurst questions
Is Flishinghurst within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you cover Flishinghurst for new build mastic?
Yes, Flishinghurst is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
Is there any odour?
There can be a smell while the sealant cures. Ventilation helps.
Where is Mr Mastic based?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
When is the best time to reseal in a new build?
It depends on whether water is getting through. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Why it’s worth doing now in Flishinghurst
A hairline gap at a skirting can wait, but a leaking seal cannot. Not sure whether yours can wait? You can ring 0345 464 0079 or drop us an email with a few pictures. In a small place like Flishinghurst, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.
