How we handle new build mastic in Chevening
We work in new homes and on new-build sites across Chevening. One shower or a whole phase of plots, the method doesn’t change: cut out, clean, prime where needed and reseal neatly. If you’re dealing with sealant applied over dusty or wet surfaces and cracks appearing as a new home settles, we can help, whatever the surface.
Somewhere as small as Chevening, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
All our work is covered by our one-year guarantee, wherever you are in Kent.

What else we do in Chevening
How we quote for new build mastic
For a quick quote, just ask. What matters most is:
- Which sealant suits the joint
- Whether old sealant or filler has to be cut out
- The size of the job
- Access and height
Doing several joints on one visit normally makes better use of the time than several visits. You’ll get one clear quote for the whole job.
Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- What’s wrong with the joints now
- Roughly how big the job is
- Where the job is, and your postcode
- Photos by email, if that is easy
Getting a quote is simple: let us know the job and the location. Photos by email help us understand the job.
What we do, step by step
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the number of plots for a typical job. Somewhere as small as Chevening, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we are working on

Do you need new build mastic in Chevening?
Sealant applied onto damp surfaces doesn’t bond well. Site programmes don’t always leave time for joints to dry before the sealant goes on.
If you can see any of these, it’s time to have the joints looked at:
- New-build shower sealant that has already split
- Skirting joints opening in the first winter
- Frame joints opening as the plaster dries
- Sealant that never bonded to the surface
If you’ve bought a new home near Dunton Green station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include
- Whether you can choose the colour
- Who does the work, and how experienced they are
- How the joint is cleaned and prepared
- What insurance they hold
What the job involves on each surface
Show homes

Yes, Chevening is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear price.

Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used.
Do you work for developers?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send us the plot schedule and we will quote.
Can I send you my snagging list?
Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before work begins.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Why does sealant fail so quickly in new builds?
New homes dry out and move in their first couple of years, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
