Sand mastic in Little Leighs, done properly
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. Common call-outs are for gaps between timber frames and stone or brick and window mastic to renew ahead of painting, on sash and case windows, tenement windows and timber door frames.
In a village or hamlet like Little Leighs, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
You get a 12-month guarantee, the same in Little Leighs as everywhere else we work.

Questions from Little Leighs
Is Little Leighs in your area for sand mastic?
Yes, Little Leighs is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear price.
I let a flat near Cressing station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
What should I tell you?
Tell us what needs doing and where, plus photos if you have them. If we need more, we will ask.
How long does the job take?
Typically it takes a few hours per window, depending on the condition of the joints. Bigger jobs take longer, and we will say how long yours will take.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.
Which is right for my windows, sand mastic or modern sealant?
Sand mastic usually suits period timber windows best. On modern frames, we’d normally use a flexible sealant.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
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.
Leave it or put it right?
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry, so dealing with it now protects both. In a small place like Little Leighs, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint generally makes the job bigger, not smaller. If you are not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.

What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Crumbling stone or brickwork round the window
- Sashes that rattle, stick or will not open
- Whether work needs listed building consent
If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before booking.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Go gently near the mastic when preparing windows
- Keep modern sealant off the mastic
- Check with your local planning authority if your home is listed
- Renew mastic before redecorating the windows
Avoid painting over the new mastic, as traditional guidance advises. If you’re redecorating, ask us first.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.
How the visit works
We keep the work tidy and contained to the joints we are treating, so you can get on with your day. Expect the work to take a few hours per window, depending on the condition of the joints, and we tell you how long to leave it before we go. In a small place like Little Leighs, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
How to prepare
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules
- Let us know about earlier repairs to the joints

London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Church of St John the Evangelist, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What we are called out for in Little Leighs
Sand mastic slowly weathers. It dries out, cracks and loses its grip on the stone or timber.
The most common problems we see are:
- Draughty sash windows at the surround
- Mastic worn away on windows facing the weather
- Cement or filler used on old window joints that has cracked
- Mastic that needs renewing before redecorating
Schools such as Great Leighs Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
