Sand mastic in Kingsclere
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. Typical jobs include old sand mastic that has cracked, crumbled or fallen out and mastic worn away on windows facing the weather, on stone surrounds, tenement windows and period & listed homes.
Homes around Kingsclere range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.

Looking after it afterwards
After the cure time, these simple habits help:
- Plan mastic work ahead of painting
- Leave the new mastic unpainted
- Keep sills and gutters clear so water drains away
- Ask the planning authority about consent for listed or conservation-area homes
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
Quotes for sand mastic in Kingsclere
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
- Working hours on commercial sites
- Whether the work is at height
What you pay reflects the work, not a rough estimate. That is why we ask about the job first.
What we need to know
When you call or email, it’s useful to know:
- What the problem is, such as mould, gaps, leaks or cracking
- Where the job is, and your postcode
- Any previous sealing or DIY work
- The rough size of the job
For a quick quote, get us on the phone, or email us if that’s easier. Describe what needs sealing and we will talk you through the work before giving you a price.
Why it’s worth doing now in Kingsclere
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. Homes in smaller places like Kingsclere 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.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
Why us?
- An ARBOMaster approved applicator
- Homes, businesses and hotels
- We never seal over old sealant
- Sanitary silicone with an anti-fungal additive in wet areas
