About our new build mastic in Holmer Green
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. If you have leaking shower tray seals in a new home and beads laid onto grit and dust from the build, we can help, whatever the surface.
Homes around Holmer Green range from older cottages to newer houses, and their floors range just as widely, from timber that moves with the seasons to tiles laid on concrete. The sealant at skirtings and thresholds has to suit the floor it meets.
All our work is covered by our one-year guarantee.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
When to call us in Holmer Green
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.
Most people get in touch after spotting something like this:
- Cracks appearing as a new home settles
- Sealant work across a run of new homes
- Sealant that never bonded to the surface
- Untidy sealant flagged on a snagging list
In and around Holmer Green, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How the visit works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It generally takes a few hours in a single home.

- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.

Why deal with it now?
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Around Holmer Green, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.

Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Avoid running a DIY bead over the old one
- Photograph failed sealant before it’s redone
- Avoid scourers and strong chemicals on sealant
- Open a window or run the fan after bathing
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it, which can damage the surface.
Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you, so raise it early.
