- The failed sealant is removed completely.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.

New build mastic in Danehill
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. Typical jobs include skirting joints opening in the first winter and cracked sealant around new window and door frames, across plot handovers, skirting & floors and show homes.
In a village or hamlet like Danehill, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.

Different surfaces, different methods
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one that suits the frame.
Kitchens
Sink joints are wet all the time. A kitchen sealant goes in there, food-safe where it’s needed.
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Avoid running a DIY bead over the old one
- Avoid scourers and strong chemicals on sealant
- Keep pictures and emails about snagging items
- Raise failed sealant with the developer while you are covered
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you so report it promptly.
When it isn’t the sealant
We’ll always be straight with you, so here’s what sealant cannot fix:
- Your warranty claim itself, which is between you and the builder
- Cracking that points to a structural problem
- Leaking fittings rather than failed sealant
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What we are called out for in Danehill
Sealant applied onto damp surfaces does not bond well. Site programmes do not always leave time for joints to dry.
The most common problems we see are:
- Gaps between new skirting and floors
- Smeared, uneven beads picked up at snagging
- Sealant that never bonded to the surface
- Second-fix sealing on new plots
In and around Danehill, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
