Sand mastic in Great Burgh, done properly
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. The old mastic is raked out, and new mastic is applied and shaped by hand. Common call-outs are for gaps round a timber door in stone or brick and tired mastic found when preparing windows for paint, across timber door frames, period & listed homes and sash and case windows.
Around Great Burgh, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
All our work is covered by a 12-month guarantee, wherever you are in Surrey.

Signs you need sand mastic in Great Burgh
Paint, silicone or cement used over old mastic causes problems. They don’t move with the timber, and they generally need raking out.
Keep an eye out for any of the following:
- A silicone bead on a sash window that spoils the look
- Tired mastic found when preparing windows for paint
- Mastic round period door frames that has failed
- Old cement repairs round a window that have failed
In the older streets around St Mark, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What your quote should include
- Whether they seal over old material or remove it
- Whether VAT is included
- How hidden problems are handled
- Which colour the sealant will be

What happens if it’s left?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and finishes neatly against the masonry. Homes in smaller places like Great Burgh can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.

How it works
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take anything from a few hours to a full day, depending on how many windows. A visit to Great Burgh is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children

How to look after the new joints
After the cure time, these simple habits help:
- Clear gutters so water does not pour onto the windows
- Check the mastic when you check the paintwork
- Go gently near the mastic when preparing windows
- Keep modern sealant off the mastic
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at before trying a quick fix.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.
What sand mastic looks like in Great Burgh
With historic houses such as Fitznells Manor (about 3 miles north) nearby, there’s older building stock in the area around Great Burgh as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as Shawley Community Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Tattenham Corner station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

Should I use sand mastic or silicone?
For period timber windows in stone or brick, sand mastic is often the better fit. On modern frames, we’d normally use a flexible sealant.

Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator.
Where is Mr Mastic based?

Do you work for landlords and businesses?

Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
What the job involves on each surface

Timber door frames
Doors face weather and wear, so their mastic can fail sooner. It’s renewed by hand.
