How we handle sand mastic in London Beach
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. Common call-outs are for a silicone bead on a sash window that spoils the look and wind and rain getting in round a sash window, on timber door frames, period & listed homes and sash and case windows.
Homes in small places like London Beach often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What sand mastic looks like in London Beach
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Smallhythe Place (about 4.2 miles south) nearby, there’s older building stock in the area around London Beach as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as St Michael's Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near Church of St Michael, the joint between an old wall and a newer frame is generally the first place rain gets in.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
When something else is needed
We’d rather tell you now than do work that will not last, so these are the limits:
- Whether work needs listed building consent
- Masonry that needs repairing
- Timber that has rotted
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.
Surfaces we seal
- Period & listed homes
- Stone surrounds
- Brick reveals
- Timber door frames
- Sash and case windows
- Tenement windows
How we quote for sand mastic
We don’t publish a price list, because jobs vary so much. What we look at:
- Working hours on commercial sites
- The product the joint needs
- Whether old sealant or filler has to be cut out
- Whether the work is at height
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

What to tell us when you ask for a quote:
- What the problem is, such as mould, gaps, leaks or cracking

What happens on the day
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to a full day, depending on how many windows. For a village or hamlet like London Beach, the journey is planned in advance: 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.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Getting ready for the visit

Landlords, agents and businesses in London Beach
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will quote.
Signs you need sand mastic in London Beach
Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
If you can see any of these, it’s time to have the joints looked at:
- Tired mastic found when preparing windows for paint
- Draughts and rain around sash boxes
- Mastic round period door frames that has failed
- Patchy fillers round a sash window
Rented homes near Pluckley station change hands often, and any sash windows need sound mastic to keep draughts and rain out.
What to look for in a quote
- How long the guarantee is
- When the joint can take water or movement
- How much experience the applicator has
- Is the old sealant removed completely?
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Ask us before painting near the mastic
- Avoid heavy scraping on the mastic joint
- Keep modern sealant off the mastic
- Make sure water runs off the sill
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
