Paddlesworth: your questions answered
Is Paddlesworth within the area you cover?

What’s sand mastic made of?
It’s the traditional filler for the joint round timber windows and doors. It combines sand with a linseed-oil-based binder.
Where are you based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Can you quote for more than one area?
Yes. Just list everything you need and you’ll get one quote.
Do you have insurance?
Yes. We are fully insured.
Can sand mastic be painted?
The usual advice is to leave sand mastic unpainted. If you are redecorating the window, ask us first and we will talk you through it.
Sand mastic in Paddlesworth, done properly
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder and built up by hand. On older homes, it suits the building far better than silicone. We work on tenement windows, period & listed homes and timber door frames, and people most often call us about cracked mastic round a front door frame and patchy fillers round a sash window.
Homes in small places like Paddlesworth 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.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

What the job involves on each surface
Timber door frames
Round a period front door, sand mastic gives the right look.
Period and listed homes
A traditional finish suits a period property, and sand mastic is one of them.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
How the visit works
When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. The work usually takes a few hours per window, depending on the condition of the joints. Somewhere like Paddlesworth needs a little journey planning: 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.
- We mix the sand mastic and apply it by hand, shaping it to the joint.

Windows and doors in Paddlesworth
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Starkey Castle (about 2.8 miles north-east) nearby, there’s older building stock in the area around Paddlesworth as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Letting a property close to Snodland station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. For site and facilities teams at buildings such as Snodland CofE Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Signs you need sand mastic in Paddlesworth
Water gets into small cracks in the mastic and loosens it further. Exposed elevations usually fail first.
These are the problems we are asked about most:
- Cement or filler used on old window joints that has cracked
- Weathered mastic on the most exposed windows
- Old sand mastic that has cracked, crumbled or fallen out
- Silicone on a period window that looks wrong
For an older house near a landmark such as St Benedict's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

- Are they insured?

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Check the mastic when you check the paintwork
- Clear gutters so water doesn’t pour onto the windows
- Keep modern sealant off the mastic
- Go gently near the mastic when preparing windows
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.
