New build mastic in Chainhurst
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks instead of bonding to the dust. We are often asked to deal with frame joints opening as the plaster dries and kitchen sealant that has pulled off the wall, on windows & doors, kitchens and plot handovers.
Work in a small place like Chainhurst just needs the journey and access planning, and once on site, the job is the same as anywhere.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

The process
At the end, we look at the finished work together and explain the cure time. The visit itself generally takes a few hours in a single home, depending on the amount of work. Somewhere like Chainhurst needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. 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.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Preparing for the visit
- Move anything stored near the joints
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts

What happens if it’s left?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. Where a wall is exposed, as many are in small places like Chainhurst, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Call for a quick quote and we’ll go through it with you.

How much does new build mastic cost in Chainhurst?
It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or drop us an email and tell us what needs doing and where.
What colour sealant will you use?
It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We’ll agree it with you first.
What information do you need?
A short description and the location, with photos by email if possible. If we need more, we’ll ask.
When is the best time to reseal in a new build?
If the seal has failed and water is getting in, do it now. Hairline cosmetic gaps can wait until the house has settled.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
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 fails, we can still redo it.
