About our sand mastic in Inkpen Common
We renew sand mastic around sash windows and doors set in stone or brick. The old mastic is raked out, and new mastic is applied and shaped by hand. Typical jobs include modern sealant on a period surround and mastic that needs renewing before redecorating, on sash and case windows, period & listed homes and stone surrounds.
Homes in small places like Inkpen Common often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
A one-year guarantee comes with the work, just as it does everywhere we cover.

How the visit works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours per window, depending on the condition of the joints. Somewhere like Inkpen Common needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Getting ready for the visit

- Tell us about any water getting in
- Keep pets and children clear of the area while we work

What else we do in Inkpen Common
What affects the cost of sand mastic
There’s no set price list. What we look at:
- The product the joint needs
- When we can work, for business premises
- How easy the joints are to reach
- Whether there’s mould to deal with
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts.
Asking for a quote
To make quoting easier, let us know:
- How many joints, rooms or windows are involved
- Access, such as stairs, a lift or height
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel
Getting a quote is simple: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.
DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Looking after it afterwards
To keep the joints looking good and working properly:
- Leave the new mastic unpainted
- Make sure water runs off the sill
- Keep modern sealant off the mastic
- Find out about consent before window work on a listed home
Do not run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
When something else is needed
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Decayed frames that need repair
- Crumbling stone or brickwork round the window
- Sash cords, weights and draught-proofing of the sashes
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before you book.
Joints and surfaces we work on
- Stone surrounds
- Tenement windows
- Sash and case windows
- Period & listed homes
- Timber door frames
- Brick reveals
Why deal with it now?
New sash windows are a major, costly change, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Around Inkpen Common, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or send us an email for an honest opinion and a quote.

Sand mastic in Inkpen Common: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Stargroves (about 2.7 miles south-east) nearby, there’s older building stock in the area around Inkpen Common as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Schools such as Inkpen Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near Church of St Laurence, the joint between an old wall and a newer frame is generally the first place rain gets in. Rented homes near Kintbury station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.
