About our sand mastic in Pested
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. We work on sash and case windows, stone surrounds and timber door frames, and people most often call us about wind and rain getting in round a sash window and old cement repairs round a window that have failed.
Mastic can only go onto a dry, clean joint, so window work in Pested is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

FAQs for Pested
Is Pested in your area for sand mastic?
Yes. Our work covers London and the South East, and Pested is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll send you a clear quote.
Will you come out to Pested?
Yes. Pested is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
How long does sand mastic take to go off?
It forms a skin fairly soon and it hardens fully over a longer time. Timing depends on the weather and the joint.
Do you guarantee sand mastic work?
There’s a 12-month guarantee on every job.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Can you seal over the old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Is it possible to take out silicone and use sand mastic instead?
Often, yes. Once the silicone is out and the joint prepared we point it with sand mastic.
Are you insured?
Yes. We’re fully insured.
Honest limits
In fairness, there are a few things sealant will not fix:
- Decayed frames that need repair
- Sash cords, weights and draught-proofing of the sashes
- Whether work needs listed building consent

Should I try it myself first?
If you are set on DIY, put the effort into 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.
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. Everything old must be removed first.
Looking after it afterwards
Aftercare is simple:
- Keep modern sealant off the mastic
- Ask a joiner to look at soft timber first
- Take care around the mastic when scraping paint
- Ask the planning authority about consent for listed or conservation-area homes
Leave the new mastic unpainted, which is the traditional advice. If you are redecorating, ask us first.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.
The process
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to a full day, depending on how many windows in most cases. Somewhere like Pested needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- We dress the finish so it sits neatly against the masonry.

Windows and doors in Pested
With historic houses such as Belmont House and Gardens (about 3.4 miles north-west) nearby, there’s older building stock in the area around Pested as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Church of St Peter include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in. If you look after a building such as Challock Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
