About our sand mastic in Cray's Pond
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditional guidance is not to paint over it, so ask us before you decorate. Common call-outs are for open joints round the window box and window mastic to renew ahead of painting, across tenement windows, period & listed homes and timber door frames.
Mastic can only go onto a dry, clean joint, so window work in Cray's Pond is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What sealant work can’t fix
Sealant isn’t the answer to every problem, and we’ll tell you before work begins. Sealant will not put right:
- Sashes that need overhauling
- Whether work needs listed building consent
- Decayed frames that need repair
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly.

Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.
How the visit works
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for a single window, longer for several. Somewhere like Cray's Pond needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
How to prepare
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive
- Clear the area around the work
How to get a quote
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. When it suits you, ring 0345 464 0079 or drop us an email.
Advice
Aftercare tips
Good habits help new joints last longer. Our tips:
- Ask us before painting near the mastic
- Look over the window mastic once a year
- Sort the mastic before the decorators arrive
- Avoid heavy scraping on the mastic joint
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at before trying a quick fix.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.
Leave it or put it right?
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic suits the building and finishes neatly against the masonry. Around Cray's Pond, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller. If you’re not sure whether it needs doing, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

What sand mastic looks like in Cray's Pond
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Basildon Park (about 2.2 miles south-west) are a reminder that the area around Cray's Pond 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.
Homes close to Church of St Leonard include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in. Letting a property close to Goring & Streatley station? Then any sash windows need sound mastic to keep draughts and rain out. For site and facilities teams at buildings such as The Oratory Preparatory School, the mastic around its windows and doors needs looking after like any other building’s.

Questions from Cray's Pond
Will you come out to Cray's Pond?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

What does sand mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Do you guarantee sand mastic work?
There’s a 12-month guarantee on every job, sand mastic included.
Can old silicone round a sash window be swapped for sand mastic?
Yes. The silicone is cut out and the joint cleaned before the sand mastic goes in.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
