Sand mastic for homes and businesses in South Chailey
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant, and we will talk through which suits your home. We work on stone surrounds, brick reveals and timber door frames, and common reasons people get in touch are mastic that needs renewing before redecorating and draughts and rain around sash boxes.
Mastic can only go onto a dry, clean joint, so window work in South Chailey is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
You are covered for a year from the day we finish. If anything is not right with it, ring 0345 464 0079 or email us.

Why act early in South Chailey
New sash windows are a major, costly change, and in listed buildings it may need consent. Where the frames are in good order, new mastic seals the surround. Around South Chailey, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Sand mastic in South Chailey: local notes
Historic houses like Anne of Cleves House (about 5 miles south) are a reminder that the area around South Chailey has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
Managing a site like Chailey School? Then its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Plumpton station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Landlords, agents and businesses in South Chailey
Letting agents and landlords in South Chailey can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The process
Before we leave, we go over the finished joints with you. The work normally takes a few hours for a single window, longer for several, depending on the size of the job. For a village or hamlet like South Chailey, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive

Advice
What the job involves on each surface
Brick reveals
An open joint at a brick reveal lets weather in. Renewing the mastic closes it.
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair, so check who is responsible first.
