Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Bepton Common and the rest of West Sussex, along with the rest of our area.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.

Yes, it’s worth checking. Your local planning authority can say if consent is needed for listed or conservation-area properties.
About our sand mastic in Bepton Common
Silicone on a period window often looks wrong and doesn’t suit the building. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. If you have draughty sash windows at the surround and mastic dropping out of the joint, we can put it right, whatever the surface.
Mastic can only go onto a dry, clean joint, so window work in Bepton Common is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Can I do it myself?
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.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
How it works
Every visit runs the same way: we check the joints, protect the area around them, do the work and tidy away. Most jobs take a few hours per window, depending on the condition of the joints. In a small place like Bepton Common, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic isn’t too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in
- Let us know about parking restrictions

Frames and glazing around Bepton Common
With historic houses such as Cowdray House (about 1.3 miles north-east) nearby, there’s older building stock in the area around Bepton Common as well as newer homes. Where a home is older, 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Roman Catholic Church of Divine Motherhood, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Common problems we fix in Bepton Common
Water gets into small cracks in the mastic and loosens it further. Windows facing the weather tend to go first.
The most common problems we see are:
- A silicone bead on a sash window that spoils the look
- Draughts and rain around sash boxes
- Weathered mastic on the most exposed windows
- Gaps between timber frames and stone or brick
For site and facilities teams at buildings such as Midhurst CofE Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Keeping the joints in good condition
Looking after new joints is easy:
- Check with your local planning authority if your home is listed
- Ask us before painting near the mastic
- Avoid patching sand mastic with silicone
- Make sure water runs off the sill
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look rather than patching it.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall, so renewing it early is worth it.
Why it’s worth doing now in Bepton Common
Not every filler suits an old window surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Around Bepton Common, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.
