Sand mastic in Bradwell, done properly
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It’s a good fit for period properties where a modern sealant bead would stand out. We are often asked to deal with failed mastic on an exposed elevation and gaps between timber frames and stone or brick, across stone surrounds, period & listed homes and sash and case windows.
In a smaller place like Bradwell, some walls face open ground and catch the full force of the weather. The mastic around frames on those walls tends to age faster.
All our work is covered by a one-year guarantee.

What sand mastic looks like in Bradwell
With historic houses such as Linford Manor (about 2 miles north-east) nearby, there’s older building stock in the area around Bradwell 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. Milton Keynes, which Bradwell is part of, is one of England’s post-war new towns. Many homes date from the post-war decades, and many will have had their original windows replaced. That mastic ages as well, and sills and frame heads are where leaks start.
If you look after a building such as Bradwell Village School, its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near Church of St Lawrence, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Milton Keynes Central station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Can I add another job to the visit?
Yes, we can. More than one area can be quoted together.
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 you match the sealant colour?
Generally, yes. Sealants come in white, clear, grey and other colours for many products, and we agree the colour with you before work begins.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Inspect the joints round the windows every year or so
- Keep sills and gutters clear so water drains away
- Find out about consent before window work on a listed home
- Avoid patching sand mastic with silicone
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
How we quote for sand mastic
Call for a quick quote. The main things that affect it are:
- Any mould that needs treating
- The number of rooms or windows
- The number and length of the joints
- Working hours on commercial sites
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Helping us quote
To make quoting easier, please include:
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
- Access, such as stairs, a lift or height
- Where the property is
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
What happens on the day
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to a full day, depending on how many windows. For a job in Bradwell, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- 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
- Mention any tricky access
- Clear items away from the joints we’re working on
- Where the joints are inside, avoid wetting them before we arrive

How the job changes by surface
Brick reveals
An open joint at a brick reveal lets weather in. New mastic seals the gap.
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.
What sealant work cannot fix
A few problems are outside what sealant work can do:
- Sashes that rattle, stick or won’t open
- Decisions on consent for listed homes
- Rotten sashes, sills or window boxes (a joiner’s job)
If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
