Sand mastic for homes and businesses in Kingsey
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It suits period and listed homes, where modern sealant can look out of place. We’re often asked to deal with mastic dropping out of the joint and gaps where the frame meets the masonry, across brick reveals, stone surrounds and timber door frames.
Outdoor sealant needs dry, clean surfaces, so work on frames around Kingsey is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Every job is covered by a one-year guarantee, wherever you are in Buckinghamshire.

Surface by surface
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We work on single windows or whole elevations.
Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. Sand mastic is shaped by hand to suit.
What we do, step by step
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. Most jobs then take a few hours per window, depending on the condition of the joints. For a village or hamlet like Kingsey, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules
- Tell us if parking is tricky

What does sand mastic cost?
Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.
Frames and glazing around Kingsey
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Haddenham & Thame Parkway station? Then any sash windows need sound mastic to keep draughts and rain out.

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
Why act early in Kingsey
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. Around Kingsey, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.

Common problems we fix in Kingsey
Previous repairs in cement or silicone often trap water or crack away. They don’t move with the timber, and they normally need raking out.
Any of these means the joints need attention:
- Wind and rain getting in round a sash window
- Silicone on a period window that looks wrong
- Failed mastic on an exposed elevation
- Mastic dropping out of the joint
For site and facilities teams at buildings such as Haddenham St Mary's Church of England School, its window and door frames need their mastic kept sound, just like a home’s.
