Why act early in Lychpit
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. Where the frames are in good order, new mastic seals the surround. Where a wall is exposed, as many are in small places like Lychpit, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Sand mastic for homes and businesses in Lychpit
We work across Lychpit renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. If you have draughty sash windows at the surround and old cement repairs round a window that have failed, we can help, on brick reveals, tenement windows and timber door frames alike.
Somewhere as small as Lychpit, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Our work is backed for twelve months, in Lychpit and everywhere else we cover.

Frames and glazing around Lychpit
Historic houses like The Vyne (about 3 miles north-west) are a reminder that the area around Lychpit has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Old Basing Infant School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Basingstoke station, any sash windows need sound mastic to keep draughts and rain out.

What affects the cost of sand mastic
Call for a quick quote. What matters most is:
- Whether there’s mould to deal with
- The number of rooms or windows
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
Combining jobs into one visit generally makes better use of the time than several visits. We’ll give you a clear price for the lot.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- The address or postcode of the job
- The rough size of the job
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
We quote each job on its own, so the first step is telling us about yours. Simply ring 0345 464 0079 or send us an email and describe the job.
When something else is needed
Before booking, it’s worth knowing the limits:
- Broken panes
- Crumbling stone or brickwork round the window

Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before you book.

- Stone surrounds
- Timber door frames
- Tenement windows
- Brick reveals
- Sash and case windows
- Period & listed homes
The process
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It usually takes anything from a few hours to a full day, depending on how many windows. Somewhere as small as Lychpit, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in

Questions from Lychpit
Will you come out to Lychpit?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Basingstoke station?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
What exactly is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and shaped to suit the surround.
Can you match the sealant colour?
Most of the time, yes. We will tell you which colours the right product comes in and agree one before we start.
Can old silicone round a sash window be swapped for sand mastic?
Yes, we do this often. The old silicone has to come out completely so the mastic can sit properly.
Can sand mastic be painted?
It’s traditionally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Can new sealant go over the old?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
When to call us in Lychpit
Age is the main cause. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
Keep an eye out for any of the following:
- Cement or filler used on old window joints that has cracked
- Window mastic to renew ahead of painting
- Wind and rain getting in round a sash window
- Open joints round the window box
If you live in an older home near Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Before you book anyone
- Whether you can choose the colour
- Whether they seal over old material or remove it
- What insurance they hold
- What happens if the job turns out different

Can I do it myself?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Different surfaces, different methods
Period and listed homes
Period homes look their best with traditional materials, and sand mastic is one of them.
Stone surrounds
We take care not to mark the stone when the old mastic comes out.
