New build mastic in Shirburn
We work in new homes and on new-build sites across Shirburn. One shower or a whole phase of plots, the method does not change: cut out, clean, prime where needed and reseal neatly. Typical jobs include kitchen sealant that has pulled off the wall and sealant that never bonded to the surface, on plot handovers, show homes and bathrooms & en suites.
In a village or hamlet like Shirburn, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Big or small, it’s backed by our one-year guarantee.

What new build mastic looks like in Shirburn

Quotes for new build mastic in Shirburn
The price is agreed before any work begins. It’s based on:
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
- The number of rooms or windows
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. Your quote takes all of that into account.

Different surfaces, different methods
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
Plot handovers
Good preparation at handover saves snagging later. Dust from the build is removed first and prime where the product needs it.

What else we do in Shirburn
When it isn’t the sealant
We’d rather tell you now than do work that won’t last, so these are the limits:
- Deciding who is responsible under a builder’s warranty
- Baths and trays that move too much for sealant to cope with
- Leaks from pipes, valves or wastes, which need a plumber
If you’re not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.
Joints and surfaces we work on
- Kitchens
- Plot handovers
- Skirting & floors
- Show homes
- Windows & doors
- Bathrooms & en suites
How to look after the new joints
To keep the joints looking good and working properly:
- Follow the cure time we give you
- Do not wait for the house to settle if water is getting through
- Look at the sealant regularly in the first couple of years
- Clean sealant with mild detergent, not abrasives
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries and can be resealed later.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will give you a quote.
Signs you need new build mastic in Shirburn
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open.
Common reasons people contact us are:
- Frame joints opening as the plaster dries
- Sealant that never bonded to the surface
- Cracked caulk along new skirting
- Smeared, uneven beads picked up at snagging
Around Shirburn, as everywhere, new build mastic is only as good as the preparation behind it.
