How we handle new build mastic in Old Basing
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. We work on skirting & floors, windows & doors and bathrooms & en suites, and people most often call us about cracks appearing as a new home settles and cracked sealant around new window and door frames.
In smaller places like Old Basing, new homes tend to come as small developments or single plots. The sealant around baths, showers, frames and skirtings needs to be right from the start.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Your questions about new build mastic in Old Basing
Do you cover smaller places like Old Basing?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Basingstoke station?

Do you guarantee your work?
Yes. All our work carries our 12-month guarantee.
Do you work through snagging lists?
Yes. Send it with pictures and we will quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
Where do you work from?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Can new sealant go on top of the old bead?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before any work starts.
Can you quote for more than one area?
Yes. Just list everything you need and you’ll get one quote.
How do I get a quote for new build mastic in Old Basing?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
Leave it or put it right?
A hairline gap at a skirting can wait, but water getting through cannot. If you’re unsure which you have, ring 0345 464 0079 or send us an email with photos. Homes in smaller places like Old Basing can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

Signs you need new build mastic in Old Basing
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
It’s worth asking for a quote if you see:
- Gaps behind new kitchen upstands
- Shower seals failing in the first year or two
- Cracked caulk along new skirting
- Beads laid onto grit and dust from the build
Around Old Basing, as everywhere, new build mastic is only as good as the preparation behind it.
What to look for in a quote

- Whether they seal over old material or remove it
- Whether you can choose the colour
- What insurance they hold
