How we handle sand mastic in Hollingdean
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. We’re often asked to deal with weathered mastic on the most exposed windows and gaps between timber frames and stone or brick, across sash and case windows, tenement windows and stone surrounds.
In a smaller place like Hollingdean, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That’s hard on the mastic around frames and sills.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

The process
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a single window, longer for several. For a job in Hollingdean, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
How to prepare
- Tell us about any water getting in
- Let us know about earlier repairs to the joints
- For indoor joints, keep the area dry beforehand if you can

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Have rotten timber repaired before new mastic goes in
- Avoid patching sand mastic with silicone
- Take care around the mastic when scraping paint
- Leave the new mastic unpainted
Do not touch or press the mastic while it hardens. It skins over quickly, but takes longer to harden fully.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.
What the job involves on each surface
Stone surrounds
Old stone surrounds are often uneven, so the gap is not the same all the way round. Sand mastic is shaped by hand to suit.
Sash and case windows
Sash windows are where we do most sand mastic work. We renew the mastic round each box.
Signs you need sand mastic in Hollingdean
Paint, silicone or cement used over old mastic causes problems. They don’t move with the timber, and they generally need raking out.
Signs it’s time to call us include:
- Gaps between timber frames and stone or brick
- Mastic worn away on windows facing the weather
- Cracked mastic round a front door frame
- Old sand mastic that has cracked, crumbled or fallen out
For site and facilities teams at buildings such as Hertford Infant and Nursery School, the mastic around its windows and doors needs looking after like any other building’s.

Your questions about sand mastic in Hollingdean
I let a flat near Moulsecoomb station. Can you help?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
Do you cover smaller places like Hollingdean?
Yes, Hollingdean is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is sand mastic better than silicone for my windows?
We’ll talk it through with you. Sand mastic suits many period homes, and modern sealants suit newer frames.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Should I check with the council before work on a listed or conservation-area home?
Checking first is sensible. Your local planning authority can say if consent is needed for work on a listed home or in a conservation area.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Hollingdean homes and the weather
Hollingdean 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. 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.
For an older house near a landmark such as St Richard's, the joint between an old wall and a newer frame is generally the first place rain gets in. For landlords with property near Moulsecoomb station, any sash windows need sound mastic to keep draughts and rain out.

Quotes for sand mastic in Hollingdean
We do not publish a price list, because jobs vary so much. The quote depends on:
- The product the joint needs
- The number of rooms or windows
- Any working-time requirements on site
- Whether old sealant or filler has to be cut out
Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Any access issues, like height or stairs
- The type of property
- The rough size of the job
- The address or postcode of the job
We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or email us.
Leave it or put it right?
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall, so dealing with it now protects both. In an older home around Hollingdean, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.
