New-build mastic & snagging in Cranbrook, Kent
Our applicators work in Cranbrook on plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly.
- Skirting joints opening in the first winter
- Smeared, uneven beads picked up at snagging
- Leaking shower tray seals in a new home
New build mastic in Cranbrook
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a seal that’s letting water through needs doing now. We work on plot handovers, kitchens and skirting & floors, and common reasons people get in touch are messy sealant that spoils new finishes and joints pulling apart as timber shrinks.
Homes around Cranbrook 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.
We stand behind the work with a one-year guarantee.

Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.

Surface by surface
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.
What we do, step by step
You don’t need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes a few hours in a single home for a typical job. A visit to Cranbrook is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely, with no layer left behind.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
How to prepare
- Mention any parking rules near the property
- For indoor joints, keep the area dry beforehand if you can
- Tell us about access, such as stairs, a lift or high-level joints

Do you need new build mastic in Cranbrook?
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
The most common problems we see are:
- Skirting joints opening in the first winter
- New-build shower sealant that has already split
- Kitchen sealant that has pulled off the wall
- Untidy sealant flagged on a snagging list
Whether the job is in Cranbrook itself or nearby, the right material for each joint matters as much as a neat finish.
What your quote should include
- Which sealant they’ll use, and why
- How much experience the applicator has
- Are they insured?
- Whether you can choose the colour
