Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Keep jet washers away from the mastic
- Keep drainage slots and sill grooves clear
- Air rooms to keep condensation down around windows
- Check the mastic once a year
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak, and if anything looks wrong, just ring 0345 464 0079 or drop us an email.
Leaks normally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
How we handle window mastic in Lockerley
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you have cracked or shrunken mastic around the frame and untidy mastic left by window fitters, we can help.
In a village or hamlet like Lockerley, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Each job carries a 12-month guarantee.

What window mastic looks like in Lockerley
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 Mottisfont Abbey (about 1.8 miles east) nearby, there’s older building stock in the area around Lockerley as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Homes close to Church of St John include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Letting a property close to Mottisfont & Dunbridge station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

How it works
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a morning for a couple of windows and a door. In a small place like Lockerley, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Mention any tricky access
- Let us know about earlier repairs to the joints
- For indoor joints, keep the area dry beforehand if you can

Is Lockerley within the area you cover?
Yes. Lockerley is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit.
I rent my home. Can I book you?

Yes. We can use white, brown, anthracite grey, black or clear.
Signs you need window mastic in Lockerley
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar never bonded as it should, so it comes away long before its time.
The most common problems we see are:
- Gaps left after new windows were fitted
- Whistling draughts around closed windows
- White mastic on grey or black frames
- Mastic that is falling out in pieces
Schools such as Lockerley Church of England Endowed Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- When the joint can take water or movement
- What guarantee comes with the work
- What insurance they hold
- Whether they seal over old material or remove it
What happens if it’s left?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. Around Lockerley, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Why book with us
- White, clear, grey or coloured to suit, where the product allows
