About our sand mastic in Bovinger
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted, so ask us before you decorate. We work on tenement windows, stone surrounds and timber door frames, and common reasons people get in touch are mastic round period door frames that has failed and old cement repairs round a window that have failed.
Homes in small places like Bovinger 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.
Big or small, you get the same one-year guarantee.

Signs you need sand mastic in Bovinger
Shallow joints are a common cause. A thin layer doesn’t hold well, which is why we pack deep voids first and get the depth right.
It’s worth asking for a quote if you see:
- Wind and rain getting in round a sash window
- Weathered mastic on the most exposed windows
- Tired mastic found when preparing windows for paint
- A silicone bead on a sash window that spoils the look
In the older streets around Church of St Germain, the joint between an old wall and a newer frame is generally the first place rain gets in.

Sand mastic in Bovinger: local notes
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 Hill Hall (about 4.3 miles south-west) are a reminder that the area around Bovinger has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you look after a building such as St Andrew's CofE Primary School, the mastic around its windows and doors needs looking after like any other building’s.

DIY sealant or a professional job?
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.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

I’m a tenant. Can you help?
We are happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Is consent needed for window work on a listed home?
Check with your local planning authority. They decide whether consent is needed.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Should I use sand mastic or silicone?
For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant, and we will explain why.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Is the work guaranteed?
Every job comes with our one-year guarantee.
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Renew mastic before redecorating the windows
- Clear gutters so water doesn’t pour onto the windows
- Have rotten timber repaired before new mastic goes in
- Inspect the joints round the windows every year or so
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.

What we do, step by step
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. In a small place like Bovinger, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
