About our new build mastic in Blean
Snagging sealant properly means taking the failed bead out completely. New silicone will not bond to old silicone, so it all comes out before we clean, dry and reseal. We work on show homes, skirting & floors and windows & doors, and the jobs we see most are sealant that never bonded to the surface and skirting joints opening in the first winter.
Work in a small place like Blean just needs the journey and access planning, and once on site, the job is the same as anywhere.
There’s a 12-month guarantee on every job, large or small.

Why it’s worth doing now in Blean
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Where a wall is exposed, as many are in small places like Blean, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.

Take a look at how sealant jobs are priced and what customers say.
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Landlord and commercial work in Blean
Housing providers, facilities teams and property managers book us too in Blean and across Kent. We can quote a run of properties together, and we are fully insured for the work.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
How it works
You do not need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes anything from a few hours to several days, depending on the number of plots in most cases. For a village or hamlet like Blean, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you’re given the cure time.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any water getting in
- Mention any tricky access

How much does new build mastic cost in Blean?

How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Can new sealant go on top of the old bead?
No. The old sealant is cut out fully, the joint cleaned and primed where needed, and a new bead applied.
How to look after the new joints
To keep the joints looking good and working properly:
- Look at the sealant regularly in the first couple of years
- Do not wait for the house to settle if water is getting through
- Avoid running a DIY bead over the old one
- Wait for the cure time before using a resealed shower
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry and can be resealed later.
Early snagging is easier snagging. Left alone, a small crack can become a leak in a busy bathroom.
