Your questions about sand mastic in Wootton
Is Wootton in your area for sand mastic?
Yes, Wootton is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
I let a flat near Tackley station. Can you help?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Is it possible to take out silicone and use sand mastic instead?
Yes. We remove the silicone and clean the joint before the sand mastic goes in.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or email us.
How long does sand mastic take to go off?
Not straight away. The skin forms first, and the full set comes later, and we’ll tell you what to expect.
Where do you work from?
Mr Mastic is based in Crawley. We cover Wootton and the rest of Oxfordshire.
Should I use sand mastic or silicone?
We’ll talk it through with you. Period homes often look best with sand mastic and newer frames suit modern sealant.
Sand mastic in Wootton, done properly
We renew sand mastic around sash windows and doors set in stone or brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. Typical jobs include draughty sash windows at the surround and silicone on a period window that looks wrong, on timber door frames, stone surrounds and brick reveals.
In a village or hamlet like Wootton, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
All our work is covered by a 12-month guarantee, wherever you are in Oxfordshire.

How we quote for sand mastic
Every job gets its own quote. This is what makes a difference:
- The product the joint needs
- Access and height
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
Asking for a quote
What to tell us when you ask for a quote:
- If it’s domestic, commercial or a hotel
- Where the property is
- Whether it has been sealed before
- The problem you’ve noticed
We don’t publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or drop us an email.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Wootton homes and the weather
Historic houses like Blenheim Palace (about 2.5 miles south) are a reminder that the area around Wootton has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Tackley station, older sash windows in a rental need their mastic kept sound to keep the weather out. Schools such as Wootton-By-Woodstock Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

- Brick reveals
- Timber door frames
- Sash and case windows
- Period & listed homes
- Stone surrounds
- Tenement windows
Aftercare tips
Looking after new joints is easy:
- Ask us before painting near the mastic
- Sort the mastic before the decorators arrive
- Go gently near the mastic when preparing windows
- Inspect the joints round the windows every year or so
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.
What we do, step by step
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. Expect the work to take anything from a few hours to a full day, depending on how many windows, and we tell you how long to leave it before we go. Somewhere as small as Wootton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Clear items away from the joints we’re working on
- Mention any tricky access
- Mention any sign-in or site rules at work premises
Getting a quote
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we’ll come back to you with a quote.

Common problems we fix in Wootton

Most people get in touch when they notice one of these:
- Gaps where the frame meets the masonry
- Mastic dropping out of the joint
- Cement or filler used on old window joints that has cracked
- Wind and rain getting in round a sash window
In the older streets around Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
