Sand mastic in Wishanger Common
On many period windows, sand mastic looks right and suits the building. Newer frames usually get a flexible sealant instead, and we’ll talk through which suits your home. Common call-outs are for wind and rain getting in round a sash window and gaps round a timber door in stone or brick, on stone surrounds, brick reveals and tenement windows.
Around Wishanger Common, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
You get a 12-month guarantee, the same in Wishanger Common as everywhere else we work.

What affects the cost of sand mastic
Call for a quick quote. What matters most is:
- The product the joint needs
- Any working-time requirements on site
- The old material and how stubborn it is
- Whether the work is at height
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
- A few pictures by email, if you can
- Roughly how big the job is
For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we will talk you through the work.
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Check the mastic when you check the paintwork
- Go gently near the mastic when preparing windows
- Ask a joiner to look at soft timber first
- Find out about consent before window work on a listed home
Keep gutters and sills clear so water runs away from the 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.
Should I try it myself first?
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.
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.
How the visit works
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes a few hours for a single window, longer for several in most cases. In a small place like Wishanger Common, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- 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.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property
- Mention any sign-in or site rules at work premises

It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you’re ready, ring 0345 464 0079 or drop us an email.

Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
