Sand mastic in Littlemore, done properly
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It’s a good fit for period properties, where modern sealant can look out of place. We are often asked to deal with mastic worn away on windows facing the weather and old sand mastic that has cracked, crumbled or fallen out, on tenement windows, stone surrounds and timber door frames.
Houses in smaller places like Littlemore can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.

Landlords, agents and businesses in Littlemore
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Why deal with it now?
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. In a smaller place like Littlemore, wherever a wall is exposed, a failed outside joint is a real source of damp. 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. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
Why book with us
- Over 20 years’ experience
- ARBOMaster approved applicator

What exactly is sand mastic?
It’s sand mixed with a linseed-oil-based binder, used between timber frames and stone or brick.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
How long will you be here?
Most jobs take anything from a few hours to a full day, depending on how many windows, including the preparation. We’ll confirm how long when we quote.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
What does sand mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Can you replace silicone on a period window with sand mastic?
In most cases. The silicone is cut out and the joint cleaned, then point it with sand mastic.
What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours for a single window, longer for several from start to finish. A visit to Littlemore 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.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic is not too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Mention any sign-in or site rules at work premises
- Tell us if parking is tricky
- Tell us about access, such as stairs, a lift or high-level joints

Advice
How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Inspect the joints round the windows every year or so
- Have rotten timber repaired before new mastic goes in
- Avoid patching sand mastic with silicone
- Ask the planning authority about consent for listed or conservation-area homes
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.
How the job changes by surface
Tenement and terrace windows
Where a building is shared, window work may involve neighbours, so check who is responsible first.
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.
Sand mastic in Littlemore: local notes
Historic houses like Holywell Manor (about 2.7 miles north) are a reminder that the area around Littlemore 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. 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.
Rented homes near Radley station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. Schools such as Emmanuel Christian School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Most people get in touch after spotting something like this:
- Mastic that needs renewing before redecorating
- Open joints round the window box
- Mastic worn away on windows facing the weather
- Mastic round period door frames that has failed
Homes close to Church of St Mary and St Nicholas include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
