Sand mastic in Dippenhall
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It’s a good fit for period properties where a modern sealant bead would stand out. If you are dealing with gaps round a timber door in stone or brick and wind and rain getting in round a sash window, we can put it right, on stone surrounds, tenement windows and sash and case windows alike.
Mastic can only go onto a dry, clean joint, so window work in Dippenhall is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Ask us before painting near the mastic
- Take care around the mastic when scraping paint
- Get any rot dealt with first
- Don’t run silicone over sand mastic
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.
What happens on the day
Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a single window, longer for several. In a small place like Dippenhall, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in
- Where the joints are inside, avoid wetting them before we arrive

Sand mastic in Dippenhall: local notes
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. Historic houses like Farnham Castle (about 1.4 miles east) are a reminder that the area around Dippenhall has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Schools such as Potters Gate CofE Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around St Francis, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

DIY sealant or a professional job?
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 doesn’t work out, we can still put it right.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What affects the cost of sand mastic
We quote each job individually. This is what makes a difference:
- Whether there’s mould to deal with
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
- Access and height
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
Helping us quote
When you call or email, it’s useful to know:
- If it’s domestic, commercial or a hotel
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
- What the problem is, such as mould, gaps, leaks or cracking
