Surface by surface
Bathrooms and en suites

Show homes
We can refresh show-home sealant that has discoloured or been knocked. The old bead comes out and a clean new one goes in.
New build mastic for homes and businesses in Purley on Thames
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation since hurried prep is behind a lot of new-build failures. We’re often asked to deal with frame joints opening as the plaster dries and sealant that never bonded to the surface, across skirting & floors, bathrooms & en suites and show homes.
If you’ve bought a new home in or near Purley on Thames, the first year or two is a good time to check the sealant. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.

Common questions in Purley on Thames
Will you come out to Purley on Thames?
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.
Can you do new build mastic in Purley on Thames?
Yes, Purley on Thames is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear price.
What does new build mastic cost?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Should I wait before resealing?
Any seal that’s leaking should be redone right away. Cosmetic gaps can wait until the first year or two of movement has passed.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Why does sealant fail so quickly in new builds?
It’s common, and there are generally two reasons: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
Where are you based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
For landlords and businesses
For anyone letting property in or around Purley on Thames, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What happens if it’s left?
DIY kits do not solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. In an older home around Purley on Thames, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Keep water off fresh sealant until it has cured
- Photograph failed sealant before it’s redone
- Watch for new gaps as the house dries out
- Avoid scourers and strong chemicals on sealant
Do not stand on the bath edge or the lip of the tray. If a bath or tray moves when you stand in it, get it looked at.
Early snagging is easier snagging. Small faults turn into leaks if left in a busy bathroom.
