Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Log resealing so you know what’s due
- Act on lifting sealant before it leaks
- Ask cleaners to go gently on the silicone
- Encourage users to squeegee shower walls
We give a cure time for every area we finish, which is usually around 24 hours. Pass it on to housekeeping or cleaners so the new sealant isn’t wetted or scrubbed too soon.
Planned resealing is easier to manage than emergency repairs. Rooms can be scheduled around occupancy and staff, instead of rooms closing without warning.

Norwood New Town: your questions answered
Can parking be tricky for a visit in Norwood New Town?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
I let a flat near Gipsy Hill station. Can you help?
Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we’ll quote it together.
Where is Mr Mastic based?
Our base is Crawley. We work across South East England, London and Scotland.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
How long will you be here?
Most jobs take a few hours per room, so whole buildings are phased. Your quote will say how long we expect yours to take.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we are using and why.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Why it’s worth doing now in Norwood New Town
Guests and staff judge a building by its bathrooms. Black sealant makes a clean room look dirty, and cleaning rarely puts it right. Replacing it does. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Norwood New Town, the repair is bigger than the sealant job would have been.
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you do try it yourself, take your time over the 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.
Landlords, agents and businesses in Norwood New Town
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.
What we are called out for in Norwood New Town
Larger buildings move, and lightweight partitions flex more than masonry. The sealant between walls, trays and fittings absorbs that strain until it tears.
Any of these means the joints need attention:
- Large numbers of bathrooms needing the same work
- Tired sealant ahead of a health and safety audit
- Split sealant around staff kitchen worktops and sinks
- Silicone laid over old silicone by a previous contractor
Schools such as Rockmount Primary School are buildings too, and sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.
What your quote should include
- How the joint is cleaned and prepared
- How much experience the applicator has
- Whether VAT is included
- What the cure time is
