Sand Mastic in Stubbles
Traditional burnt sand mastic around sash and case windows and doors in stone and brick for householders, landlords and businesses in Stubbles. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Draughty sash windows at the surround
- Modern sealant on a period surround
- Mastic worn away on windows facing the weather
What happens if it’s left?
New sash windows are a major, costly change and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. Around Stubbles, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before we start, so you know where you stand.

About our sand mastic in Stubbles
A silicone bead around a sash window can look out of place and doesn’t suit the building. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. If you are dealing with draughts and rain around sash boxes and old cement repairs round a window that have failed, we can help, on period & listed homes, timber door frames and brick reveals alike.
Outdoor sealant needs dry, clean surfaces, so work on frames around Stubbles is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Each job carries a 12-month guarantee.

Windows and doors in Stubbles
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Basildon Park (about 2.5 miles north-east) nearby, there’s older building stock in the area around Stubbles 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.
If you live in an older home near Church of St Clement, the joint between an old wall and a newer frame is generally the first place rain gets in.

Stubbles questions
Can you do sand mastic in Stubbles?
Yes. Our work covers London and the South East, and Stubbles is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
Will you come out to Stubbles?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Can sand mastic be painted?
It’s traditionally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Can landlords and businesses book you?
Yes. We work for householders, landlords, letting agents, businesses and hotels in Stubbles.
What we do, step by step
You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to a full day, depending on how many windows in most cases. In a small place like Stubbles, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Preparing for the visit
- Let us know about parking restrictions
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed

Advice
Landlords, agents and businesses in Stubbles
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Keeping the joints in good condition
So the new joints stay in good condition:
- Ask the planning authority about consent for listed or conservation-area homes
- Keep modern sealant off the mastic
- Avoid heavy scraping on the mastic joint
- Plan mastic work ahead of painting
Leave the new mastic unpainted, which is the traditional advice. If you’re redecorating, ask us first.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger.
Different surfaces, different methods
Brick reveals
Gaps between frame and brick let in rain and draughts. New mastic seals the gap.
Period and listed homes
On a listed home or in a conservation area, the right material matters. Like-for-like sand mastic is normally favoured.
