Ansty homes and the weather
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. With historic houses such as Ockenden Manor (about 1.2 miles north-east) nearby, there’s older building stock in the area around Ansty as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Haywards Heath station, older sash windows in a rental need their mastic kept sound to keep the weather out. Homes close to St John the Evangelist include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Sand mastic in Ansty, done properly
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditionally, sand mastic is left unpainted, so ask us before you decorate. We’re often asked to deal with patchy fillers round a sash window and window mastic to renew ahead of painting, across sash and case windows, stone surrounds and timber door frames.
Homes in small places like Ansty 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.
Big or small, it’s backed by our 12-month guarantee.

How the visit works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours per window, depending on the condition of the joints. For a village or hamlet like Ansty, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Getting ready for the visit

Common problems we fix in Ansty
Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
Look out for any of the following:
- Crumbling sand mastic round a window
- Window mastic to renew ahead of painting
- Mastic round period door frames that has failed
- Weathered mastic on the most exposed windows
If you look after a building such as Warden Park School, the mastic around its windows and doors needs looking after like any other building’s.

What guarantee comes with the work?

Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
How long will you be here?
It depends on the size of the job, but most jobs take anything from a few hours to a full day, depending on how many windows. We’ll give you a better idea when we quote.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Which is right for my windows, sand mastic or modern sealant?
That depends on your windows. Period windows in stone or brick usually suit sand mastic and newer frames normally get a flexible sealant.

Why it’s worth doing now in Ansty
A silicone bead can be quicker, 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. Where a wall is exposed, as many are in small places like Ansty, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Why Ansty clients choose us

Aftercare tips
So the new joints stay in good condition:
- Inspect the joints round the windows every year or so
- Make sure water runs off the sill
- Avoid heavy scraping on the mastic joint
- Find out about consent before window work on a listed home
Don’t touch or press the mastic while it hardens. It skins over quickly, but takes longer to harden fully.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.
