Signs you need sand mastic in Chegworth
Age is the main cause. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
Signs it’s time to call us include:
- Mastic that needs renewing before redecorating
- Mastic dropping out of the joint
- A silicone bead on a sash window that spoils the look

In the older streets around Church of St Margaret, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How we handle sand mastic in Chegworth
We work across Chegworth renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. Typical jobs include tired mastic found when preparing windows for paint and mastic round period door frames that has failed, across brick reveals, sash and case windows and tenement windows.
Around Chegworth, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Big or small, you get the same 12-month guarantee.

Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
How it works
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a single window, longer for several. Somewhere like Chegworth needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Mention any tricky access
- Let us know if you’ve seen damp or leaks

Advice
What sand mastic looks like in Chegworth
With historic houses such as Leeds Castle (about 0.9 miles west) nearby, there’s older building stock in the area around Chegworth as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Harrietsham station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. For site and facilities teams at buildings such as Harrietsham Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Chegworth: your questions answered
Can you help a landlord with a rental near Harrietsham station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Do you cover smaller places like Chegworth?
Yes, Chegworth 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.
Is it OK to seal over old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Can you match the sealant colour?
Yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before work begins.
What’s sand mastic made of?
It’s sand mixed with a linseed-oil-based binder for the joint between timber frames and masonry.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Surface by surface
Brick reveals
We rake out the old mastic and pack deep voids before the new mastic goes in.
Timber door frames
Doors face weather and wear and the mastic can crack early. It’s renewed by hand.
Landlords, agents and businesses in Chegworth
We also work for property managers and facilities teams. Several sites can be quoted together, and we are fully insured for the work.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Honest limits
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Planning or listed building consent (your local planning authority decides)
- Sashes that need overhauling
- Cracked or broken glass
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before booking.
Where we work in Chegworth
- Sash and case windows
- Tenement windows
- Timber door frames
- Brick reveals
- Stone surrounds
- Period & listed homes
Leave it or put it right?
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. Around Chegworth, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.
