Frames and glazing around Singleton
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as West Dean House (about 1.2 miles west) nearby, there’s older building stock in the area around Singleton as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you live in an older home near The Parish Church of the Blessed Virgin Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as Singleton CofE Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Sand mastic in Singleton
We work across Singleton renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand, finished to suit the masonry. If you have cement or filler used on old window joints that has cracked and mastic round period door frames that has failed, we can help.
In a village or hamlet like Singleton, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Our work is backed for twelve months.

Landlord and commercial work in Singleton
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
If you manage several properties in or around Singleton, several properties can go on one quote. Just tell us the addresses and what each one needs.
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Singleton questions
Can you do sand mastic in Singleton?
Yes. We work across London and the South East, and Singleton is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear price.
Is Singleton within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Where do you work from?
We are a Crawley-based firm. Our area covers South East England, London and Scotland.
Can old silicone round a sash window be swapped for sand mastic?
Yes, we do this often. The old silicone has to come out completely so the mastic can sit properly.
Can you match the sealant colour?
Yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before work begins.
I rent my home. Can I book you?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

What happens on the day
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours per window, depending on the condition of the joints. In a small place like Singleton, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Getting ready for the visit

Related advice
Why deal with it now?
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall so renewing it early protects the window. Older cottages and farmhouses around Singleton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
