New build mastic in Wendover Dean, done properly
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a seal that is letting water through needs doing now. If you’re dealing with cracked caulk along new skirting and shower seals failing in the first year or two, we can help, on plot handovers, skirting & floors and kitchens alike.
Work in a small place like Wendover Dean just needs the journey and access planning, and once on site, the job is the same as anywhere.
There’s a 12-month guarantee on every job, large or small.

Quotes for new build mastic in Wendover Dean
Your quote is based on your job. We take into account:
- The amount of work
- How many rooms, windows or areas are involved
- Whether there’s mould to deal with
- The product the joint needs
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
What we need to know
Photos help, but a description is a good start. Please mention:
- Any access issues, like height or stairs
- The address or postcode of the job
- If someone has resealed it before
- The rough size of the job
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or email us.
When to call us in Wendover Dean
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and can tear.
Look out for these signs:
- Frame joints opening as the plaster dries
- Cracked caulk along new skirting
- Gaps behind new kitchen upstands
- Plot mastic for developers ahead of handover
Around Wendover Dean, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before booking
- What insurance they hold
- What preparation is included
- Who turns up on the day
- Whether the sealant suits the joint
Leave it or put it right?
The builder is generally the first port of call while the snagging or warranty period runs. If it keeps failing or is not dealt with, we can reseal it properly. Older cottages and farmhouses around Wendover Dean can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why book with us
- Any old sealant cut out fully, not covered over
- White, clear, grey or coloured to suit, where the product allows
- A 12-month guarantee on all work
- 180+ five-star Google reviews

Can you do new build mastic in Wendover Dean?
Yes, Wendover Dean is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Will you come out to Wendover Dean?
Yes. Wendover Dean is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Are you insured?
Yes, we’re fully insured.
Will you just run a new bead over the existing one?
No. Fresh silicone does not stick to the old layer, so it soon lifts and traps water. We cut the old bead out completely.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
