How the job changes by surface
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. We renew it the same way as on windows.
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.
Sand mastic for homes and businesses in Turville
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. We work on stone surrounds, period & listed homes and brick reveals, and common reasons people get in touch are old cement repairs round a window that have failed and failed mastic on an exposed elevation.
Outdoor sealant needs dry, clean surfaces, so work on frames around Turville is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

FAQs for Turville
Will you come out to Turville?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
What guarantee comes with sand mastic in Turville?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
What exactly is sand mastic?
Sand mastic is a traditional material for pointing round windows and doors. It’s made with sand and a linseed-oil-based binder.
Do you offer different sealant colours?
Usually, yes. White, clear and grey are common, and other colours are available, and we will agree it with you first.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Can old silicone round a sash window be swapped for sand mastic?
Yes, it’s a common request. All the old silicone is removed first so the mastic beds in well.
Where do you work from?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

What sand mastic looks like in Turville
With historic houses such as Stonor Park (about 2 miles south-west) nearby, there’s older building stock in the area around Turville 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 an older house near a landmark such as Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Common problems we fix in Turville
Previous repairs in cement or silicone often trap water or crack away. They do not move with the timber and we normally remove them.
The problems people normally mention when they call include:
- Draughts and rain around sash boxes
- Patchy fillers round a sash window
- Cracked mastic round a front door frame
- Open joints round the window box
If you look after a building such as Ibstone CofE Primary School, the mastic around its windows and doors needs looking after like any other building’s.
What to look for in a quote
- How long to leave it before use
- How the colour is chosen
- What happens if they find a problem under the old sealant
- Whether they’re fully insured
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Go gently near the mastic when preparing windows
- Avoid patching sand mastic with silicone
- Ask a joiner to look at soft timber first
- Do not paint over the new mastic
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.
What affects the cost of sand mastic
We don’t publish a price list, because no two jobs are the same. What we look at:
- The old material and how stubborn it is
- Which sealant suits the joint
- Any mould that needs treating
- How many rooms, windows or areas are involved
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.
What to tell us for a quote
To make quoting easier, let us know:
- Roughly how big the job is
- Any previous sealing or DIY work
- A few pictures by email, if you can
- Access, such as stairs, a lift or height
There’s no standard price list. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or send us an email.
Landlord and commercial work in Turville
Housing providers, facilities teams and property managers book us too in Turville and across Oxfordshire. Several sites can be quoted together, and we’re fully insured.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will quote.
What happens if it’s left?
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic matches what was there and that can be important for listed homes. Around Turville, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or email us and we will give you an honest view and a quote.

The process
We keep the work tidy and contained to the area we’re working on, so you can get on with your day. Expect the work to take a few hours per window, depending on the condition of the joints, and we tell you how long to leave it before we go. In a small place like Turville, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises
- Plan for the work area to be out of bounds to pets and children
