How we handle new build mastic in Benhilton
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. We work on windows & doors, skirting & floors and bathrooms & en suites, and the jobs we see most are gaps behind new kitchen upstands and shower seals failing in the first year or two.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, while new homes need a neat, sound finish around frames, baths and kitchens before handover.
Whatever the size of the job, you get the same 12-month guarantee.

Benhilton: your questions answered
Is parking an issue for new build mastic in Benhilton?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Do you cover Benhilton for new build mastic?
Yes. Our work covers London and the South East, and Benhilton is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Is there a guarantee?
Yes. Every job comes with our one-year guarantee.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages.
What sealant work can’t fix
We will always be straight with you, so here’s what sealant cannot fix:
- Movement caused by a poorly fitted tray or bath
- Leaks from pipes, valves or wastes, which need a plumber
- Damaged fittings that need replacing
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before booking.

Joints and finishes in Benhilton homes
Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Benhilton is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Do you need new build mastic in Benhilton?
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Look out for these signs:
- Gaps opening as the house dries out and settles
- Worktop and upstand sealant coming away
- Leaking shower tray seals in a new home
- Sealant that never bonded to the surface
If you’ve bought a new home near Sutton Common station, the sealant around baths, showers and frames is worth checking in the first year or two.

What affects the cost of new build mastic
We do not publish a price list, because no two jobs are the same. The quote depends on:
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
- The product the joint needs
- The number and length of the joints
What you pay reflects the work, not guesswork. That’s why we ask about the job first and give you a clear quote before we start.
What to tell us for a quote
When you contact us, these details help:
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
- Where the property is
- If it’s domestic, commercial or a hotel
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, ring 0345 464 0079 or send us an email.
Why act early in Benhilton
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Benhilton, the repair is bigger than the sealant job would have been.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Why book with us
- Anti-fungal silicone where joints get wet
- An ARBOMaster approved applicator
- White, clear, grey or another colour, product permitting
- Homes, businesses and hotels
Take a look at our cost guide or customer reviews.
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Do not wait for the house to settle if water is getting through
- Look at the sealant regularly in the first couple of years
- Resist patching a failed seal with a tube from the DIY shop
- Wait for the cure time before using a resealed shower
Don’t stand on the bath edge or the lip of the tray in the first few weeks. Report any movement in a bath or tray.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak.
