Sand mastic for sash & case windows in Burford, Oxfordshire
Problem with your window and door surrounds in Burford? We remove the old material, prepare the joints and seal them properly.
- Mastic dropping out of the joint
- Gaps round a timber door in stone or brick
- Tired mastic found when preparing windows for paint
How we handle sand mastic in Burford
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted, so ask us before you decorate. If you have patchy fillers round a sash window and gaps where the frame meets the masonry, we can put it right.
In a smaller place like Burford, some walls face open ground and catch the full force of the weather. That is hard on the mastic around frames and sills.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Make sure water runs off the sill
- Get any rot dealt with first
- Renew mastic before redecorating the windows
- Avoid patching sand mastic with silicone
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.

What does sand mastic cost?
It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or drop us an email with a short description of the job.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
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.

Where are you based?

Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Why deal with it now?
Draughts round a sash window are not always the sashes. Open mastic joints round the box can let air in, and renewing the mastic closes them. Around Burford, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

What affects the cost of sand mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether there’s mould to deal with
- Whether the work is at height
- How many rooms, windows or areas are involved
- Working hours on commercial sites
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and send you a clear quote before we start.
What we need to know
What to tell us when you ask for a quote:
- The problem you’ve noticed
- If someone has resealed it before
- Access, such as stairs, a lift or height
- Whether it’s a home or a business
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will explain what’s involved.
When it isn’t the sealant
To be straight with you, there are a few things sealant will not fix:
- Timber that has rotted
- Sash cords, weights and draught-proofing of the sashes
- Broken panes
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly.

Common problems we fix in Burford
Timber swells and shrinks with the weather. The movement cracks the mastic little by little.
If you can see any of these, it’s time to have the joints looked at:
- Tired mastic found when preparing windows for paint
- Patchy fillers round a sash window
- Gaps where the frame meets the masonry
- Gaps round a timber door in stone or brick
If you live in an older home near Church of St John the Baptist, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Before booking anyone

- Whether you can choose the colour
- What preparation is included
- Whether they seal over old material or remove it

What else we do in Burford
What sand mastic looks like in Burford
With historic houses such as Minster Lovell Hall (about 4.4 miles east) nearby, there’s older building stock in the area around Burford as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Burford Primary School, larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Shipton station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

What we do, step by step
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours per window, depending on the condition of the joints, depending on how much there is to do. Parking around Burford is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- 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 isn’t too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Before we arrive
- Clear the area around the work
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints
