Sand mastic for homes and businesses in Filching
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. We rake it out and renew it and tidies the surround. If you have cement or filler used on old window joints that has cracked and failed mastic on an exposed elevation, we can help, whatever the surface.
Homes in small places like Filching often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Each job carries a 12-month guarantee, large or small.

Aftercare tips
After the cure time, these simple habits help:
- Find out about consent before window work on a listed home
- Take care around the mastic when scraping paint
- Sort the mastic before the decorators arrive
- Leave the new mastic unpainted
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Sand mastic in Filching: local notes
With historic houses such as Alfriston Clergy House (about 2.9 miles west) nearby, there’s older building stock in the area around Filching as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Willingdon Primary School, larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Polegate station, any sash windows need sound mastic to keep draughts and rain out. For an older house near a landmark such as The Parish Church of Saint Peter, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What happens if it’s left?
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. Older cottages and farmhouses around Filching can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not guesswork. That is why we ask about the job first.

How the visit works
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours per window, depending on the condition of the joints. In a small place like Filching, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- 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
- Clear items away from the joints we’re working on
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children
