Sand mastic for sash & case windows in Little London, Buckinghamshire
We cover Little London for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly.
- Cement or filler used on old window joints that has cracked
- Mastic worn away on windows facing the weather
- Draughts and rain around sash boxes
What sealant work can’t fix
New sealant can’t fix everything, and we’ll tell you before we start. It will not solve:
- Crumbling stone or brickwork round the window
- Decisions on consent for listed homes
- Sashes that rattle, stick or will not open
If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer.

How we handle sand mastic in Little London
Sand mastic does not last for ever and gaps open up round the frame. We rake it out and renew it and tidies the surround. We work on tenement windows, sash and case windows and stone surrounds, and common reasons people get in touch are gaps between timber frames and stone or brick and mastic dropping out of the joint.
Around Little London, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Our work is backed for twelve months.

Sand mastic in Little London: local notes
With historic houses such as Boarstall Tower (about 1.7 miles north-west) nearby, there’s older building stock in the area around Little London 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. 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.
Homes close to Church of St Mary include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in. Schools such as Oakley Church of England Combined School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Renew mastic before redecorating the windows
- Go gently near the mastic when preparing windows
- Clear gutters so water doesn’t pour onto the windows
- Have rotten timber repaired before new mastic goes in
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look rather than patching it.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Common questions in Little London
Is there a guarantee on sand mastic in Little London?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Is Little London in your area for sand mastic?
Yes, Little London is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear price.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Is sand mastic better than silicone for my windows?
We’ll talk it through with you. Sand mastic suits many period homes, and modern sealants suit newer frames.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. If you are redecorating the window, ask us first and we’ll advise.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
Do you work for landlords and businesses?
Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

How it works
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take anything from a few hours to a full day, depending on how many windows. In a small place like Little London, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Tell us about any water getting in
- Let us know about earlier repairs to the joints
- Mention any parking rules near the property

Why deal with it now?
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. Where the frames are in good order, new mastic seals the surround. Where a wall is exposed, as many are in small places like Little London, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
