New build mastic for homes and businesses in Highstreet
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first. If you’re dealing with kitchen sealant that has pulled off the wall and untidy sealant flagged on a snagging list, we can put it right, on bathrooms & en suites, kitchens and plot handovers alike.
In a village or hamlet like Highstreet, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

FAQs for Highstreet
Will you come out to Highstreet?
Yes, Highstreet is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Are you ARBOMaster approved?

I rent my home. Can I book you?

What colour sealant will you use?
The colour is chosen to suit the tiles, worktop or frame. Let us know your preference when you ask for a quote.
Is it normal for sealant to crack in a new home?
New homes dry out and move in their first couple of years, and sealant is often rushed onto dusty, unprimed surfaces. Either can make it fail early.
How the visit works
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours in a single home.

We bring what the job needs, so it can be finished in one trip where possible.
- Each joint is checked for movement before we start.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.

New build mastic in Highstreet: local notes
Highstreet is within about 2 miles of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For new homes near Whitstable station, it’s worth checking the sealant early, while snags are still fresh. Around Highstreet, as everywhere, new build mastic is only as good as the preparation behind it.
Highstreet is about 3 miles south-west of Whitstable, in Kent. For new build mastic in and around Highstreet, please ring 0345 464 0079 or drop us an email for a quick quote.

What the job involves on each surface
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish. Tell us when the home is open so we can plan around it.
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
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.
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Resist patching a failed seal with a tube from the DIY shop
- Clean sealant with mild detergent, not abrasives
- Follow the cure time we give you
- Open a window or run the fan after bathing
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers so moisture doesn’t sit on the sealant.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small.
Honest limits
It helps to know what we can’t do too:
- Disputes or warranty claims with your builder
- Cracked trays, tiles or worktops
- Structural cracks in walls or ceilings
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly before you book.
