How we handle sand mastic in Tunstall
Sand mastic doesn’t last for ever, leaving gaps round the window. We rake it out and renew it so the surround looks right again. If you’re dealing with weathered mastic on the most exposed windows and draughts and rain around sash boxes, we can put it right, whatever the surface.
Homes in small places like Tunstall often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What affects the cost of sand mastic
For a quick quote, just ask. What matters most is:
- Whether the work is at height
- Whether there’s mould to deal with
- When we can work, for business premises
- The size of the job
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.
Helping us quote
To help us quote quickly, please include:
- Whether it’s a home or a business
- What the problem is, such as mould, gaps, leaks or cracking
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
For a quick quote, get us on the phone, or email us if that is easier. Tell us about the joints that need doing and we’ll talk you through the work.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Take care around the mastic when scraping paint
- Ask a joiner to look at soft timber first
- Plan mastic work ahead of painting
- Ask us before painting near the mastic
Do not touch or press the mastic while it hardens. It skins over quickly, but takes longer to harden fully.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you do try it yourself, take your time over the 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.
When it is not the sealant
To be straight with you, there are a few things sealant won’t fix:
- Sashes that need overhauling
- Whether work needs listed building consent
- Decayed frames that need repair
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.

Tunstall homes and the weather
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.
For an older house near a landmark such as Church of St John the Baptist, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as Tunstall Church of England (Aided) Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Sittingbourne station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

Why it’s worth doing now in Tunstall
An open joint round the frame lets weather in. Left, water can reach the timber and the wall, so dealing with it now protects both. Where a wall is exposed, as many are in small places like Tunstall, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.

How the visit works
Every visit runs the same way: we check the joints, protect the area around them, do the work and tidy away. It usually takes a few hours per window, depending on the condition of the joints. Somewhere as small as Tunstall, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises
