About our new build mastic in Windmill Hill
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. We’re often asked to deal with plot mastic for developers ahead of handover and sealant that never bonded to the surface, on bathrooms & en suites, plot handovers and kitchens.
Somewhere as small as Windmill Hill, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
Big or small, you get the same 12-month guarantee.

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
How the visit works
We keep the work tidy and contained to the joints we are treating. The job generally takes anything from a few hours to several days, depending on the number of plots, and we explain the cure time before we leave. Somewhere as small as Windmill Hill, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Mention any tricky access
- On commercial sites, let us know about site rules
- Let us know about earlier repairs to the joints
How to get a quote

What else we do in Windmill Hill
Do you need new build mastic in Windmill Hill?
On many sites, sealant goes on in the final rush before handover. Joints aren’t always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
People usually contact us when they notice one of these:
- Sealant that never bonded to the surface
- Cracked sealant around new window and door frames
- Skirting joints opening in the first winter
- Gaps opening as the house dries out and settles
In and around Windmill Hill, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Why act early in Windmill Hill
DIY kits do not solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. Older cottages and farmhouses around Windmill Hill can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
Why us?
- Approved under the ARBOMaster scheme

Is it worth resealing while the house is still settling?

Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Don’t wait for the house to settle if water is getting through
- Keep water off fresh sealant until it has cured
- Resist patching a failed seal with a tube from the DIY shop
- Open a window or run the fan after bathing
Do not stand on the bath edge or the lip of the tray. Report any movement in a bath or tray.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
