Sand mastic for homes and businesses in Bartley
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On older homes, it suits the building far better than silicone. Typical jobs include window mastic to renew ahead of painting and open joints round the window box, on tenement windows, stone surrounds and timber door frames.
In a village or hamlet like Bartley, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Big or small, it’s backed by our one-year guarantee in Bartley and across Hampshire.

What affects the quote in Bartley
The quote reflects the job in front of us. We take into account:
- Whether old sealant or filler has to be cut out
- Any working-time requirements on site
- Whether there’s mould to deal with
- Which sealant suits the joint
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
Asking for a quote
To make quoting easier, please include:
- The problem you’ve noticed
- How many joints, rooms or windows are involved
- How we’d reach the joints
- The address or postcode of the job
There’s no standard price list. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or email us.
How to look after the new joints
After the cure time, these simple habits help:
- Get any rot dealt with first
- Keep sills and gutters clear so water drains away
- Take care around the mastic when scraping paint
- Ask the planning authority about consent for listed or conservation-area homes
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

What else we do in Bartley
Surface by surface
Stone surrounds
Sand mastic sits naturally against stone. The finish blends with the masonry.
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
Why deal with it now?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and blends with the stone or brick. Around Bartley, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

The process
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a single window, longer for several. Somewhere like Bartley 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.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- 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.
Preparing for the visit
- Tell us about any water getting in
- Mention any tricky access
- Let us know about earlier repairs to the joints
