About our sand mastic in Kingswood
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. We work on stone surrounds, sash and case windows and tenement windows, and common reasons people get in touch are patchy fillers round a sash window and mastic round period door frames that has failed.
In a smaller place like Kingswood, 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.
Each job carries a 12-month guarantee.

Kingswood homes and the weather
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Fitznells Manor (about 4.6 miles north) nearby, there’s older building stock in the area around Kingswood as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Kingswood station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. Homes close to Church of St Andrew include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What we’re called out for in Kingswood
Previous repairs in cement or silicone often trap water or crack away. They do not suit the joint, and they normally need raking out.

- Crumbling sand mastic round a window
- Wind and rain getting in round a sash window
- Window mastic to renew ahead of painting
- Cement or filler used on old window joints that has cracked
If you look after a building such as Tadworth Primary School, the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before you book
- When the joint can take water or movement
- Whether they seal over old material or remove it
- Are they insured?
- What happens if they find a problem under the old sealant

What else we do in Kingswood
What happens if it’s left?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. In an older home around Kingswood, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

How the visit works
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours per window, depending on the condition of the joints. A visit to Kingswood is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Tell us about access, such as stairs, a lift or high-level joints
- Mention if the joints have been sealed before

When it isn’t the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Whether work needs listed building consent
- Damaged stone surrounds
- Sashes that rattle, stick or won’t open
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.
