- Mastic round period door frames that has failed
- Gaps between timber frames and stone or brick

Common problems we fix in Friston
Timber frames move with the seasons. That movement opens up the mastic joint little by little.
It’s worth asking for a quote if you see:
- Gaps where the frame meets the masonry
- Cracked mastic round a front door frame
- Tired mastic found when preparing windows for paint
- Modern sealant on a period surround
If you let a flat or house near Eastbourne station, any sash windows need sound mastic to keep draughts and rain out.
What your quote should include
- Whether the sealant suits the joint
- Who does the work, and how experienced they are
- Whether VAT is included
- Whether they seal over old material or remove it
About our sand mastic in Friston
We work across Friston renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. We’re often asked to deal with mastic worn away on windows facing the weather and a silicone bead on a sash window that spoils the look, on brick reveals, tenement windows and period & listed homes.
Many houses in smaller places like Friston have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

Why it’s worth doing now in Friston
If you are redecorating, renew the mastic first. Painting over failed mastic doesn’t seal it, and the new mastic is traditionally left unpainted. In an older home around Friston, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

What the job involves on each surface
Stone surrounds
Sand mastic sits naturally against stone. It finishes to look like part of the surround.
Sash and case windows
On a sash window, the mastic joint shows on the outside so we finish it carefully.
FAQs for Friston
Will you come out to Friston?
Yes, Friston is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is sand mastic in a coastal place like Friston any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
I rent my home. Can I book you?
Yes. Check with your landlord; we can send the quote to them too.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit.
Can you replace silicone on a period window with sand mastic?
Often, yes. With the silicone removed and the joint cleaned we point it with sand mastic.
What guarantee comes with the work?
All our work has a 12-month guarantee.
What is sand mastic?
Sand mastic is a traditional material for pointing round windows and doors. It combines sand with a linseed-oil-based binder.
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: 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 we quote for sand mastic
The quote reflects the job in front of us. We look at:
- Any mould that needs treating
- Access and height
- How many rooms, windows or areas are involved
- How much there is to do
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Pictures of the joints, sent by email
- Whether it has been sealed before
- Whether it’s a home or a business
- Where the property is
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.
What we do, step by step
You do not need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes a few hours per window, depending on the condition of the joints for a typical job. For a job in Friston, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
How to prepare
- Let us know if you’ve seen damp or leaks
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive

Sand mastic in Friston: local notes
Friston is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Historic houses like Alfriston Clergy House (about 3.7 miles north-west) are a reminder that the area around Friston has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you live in an older home near The Parish Church of St Simon and St Jude, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
