Sand mastic in Lower Shiplake
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It’s a good fit for period properties, where modern sealant can look out of place. Common call-outs are for cracked mastic round a front door frame and old sand mastic that has cracked, crumbled or fallen out, on brick reveals, sash and case windows and stone surrounds.
In a village or hamlet like Lower Shiplake, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
There’s a 12-month guarantee on every job, large or small.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Inspect the joints round the windows every year or so
- Keep modern sealant off the mastic
- Check with your local planning authority if your home is listed
- Ask us before painting near the mastic
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.

Sand mastic in Lower Shiplake: local notes
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. Historic houses like Greenlands (about 3.6 miles north) are a reminder that the area around Lower Shiplake has older buildings as well as new. 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.
Homes close to Church of St Mary include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in. If you look after a building such as Shiplake Church of England School, its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Shiplake station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes anything from a few hours to a full day, depending on how many windows, including the tidy-up. In a small place like Lower Shiplake, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Let us know about earlier repairs to the joints
- Let us know about stairs, lifts or work at height

What affects the cost of sand mastic
We don’t publish a price list. What we look at:
- The old material and how stubborn it is
- The product the joint needs
- Whether there’s mould to deal with
- How easy the joints are to reach
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- The type of property
- The address or postcode of the job
- Any previous sealing or DIY work
- What the problem is, such as mould, gaps, leaks or cracking
Need a quote? Please ring 0345 464 0079 or drop us an email and tell us about the job. You’ll know what we plan to do, and what it will cost, before any work begins.
Why deal with it now?
An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. Around Lower Shiplake, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
