Sand mastic in Headington Quarry
We renew sand mastic around sash windows and doors in stone and brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. If you are dealing with modern sealant on a period surround and mastic dropping out of the joint, we can put it right.
In a smaller place like Headington Quarry, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That is hard on the mastic around frames and sills.
You are covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

Windows and doors in Headington Quarry
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 Holywell Manor (about 2 miles west) nearby, there’s older building stock in the area around Headington Quarry as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Schools such as Headington Quarry Foundation Stage School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Oxford station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. In the older streets around Holy Trinity Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Landlords, agents and businesses in Headington Quarry
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
We work for landlords and letting agents as well as homeowners. Sealant work between tenants keeps a property looking cared for.
What we do, step by step
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take a few hours for a single window, longer for several. In a smaller place like Headington Quarry, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- 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 mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Clear the area around the work
- For business premises, tell us about site rules or sign-in

Advice
Why it’s worth doing now in Headington Quarry
Not every filler suits an old window surround. Sand mastic matches what was there and that can be important for listed homes. Homes in smaller places like Headington Quarry can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Ask the planning authority about consent for listed or conservation-area homes
- Renew mastic before redecorating the windows
- Leave the new mastic unpainted
- Take care around the mastic when scraping paint
Do not touch or press the mastic while it hardens. It forms a skin fairly soon but needs longer to fully harden.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
FAQs for Headington Quarry
I let a flat near Oxford station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.
Can you do sand mastic in Headington Quarry?
Yes. We work across London and the South East, and Headington Quarry is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area.
What’s sand mastic made of?
Sand mastic is a traditional material for pointing round windows and doors. It’s made with sand and a linseed-oil-based binder.
Can old silicone round a sash window be swapped for sand mastic?
In most cases. We remove the silicone and clean the joint, then point it with sand mastic.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
