How we handle sand mastic in Balls Green

Across Balls Green, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand for a neat, traditional finish. If you have silicone on a period window that looks wrong and window mastic to renew ahead of painting, we can put it right.

Somewhere as small as Balls Green, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.

You get a 12-month guarantee, the same in Balls Green as everywhere else we work.

How to look after the new joints

So the new joints stay in good condition:

  • Plan mastic work ahead of painting
  • Take care around the mastic when scraping paint
  • Make sure water runs off the sill
  • Get any rot dealt with first

Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look rather than patching it.

Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.

Balls Green homes and the weather

Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Bassetts Manor (about 2.2 miles north-west) nearby, there’s older building stock in the area around Balls Green as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.

Schools such as St Michael's Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Ashurst Kent station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Should I try it myself first?

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.

If you’ve already had a go yourself, that is fine. We cut it out and start again.

Signs you need sand mastic in Balls Green

Age is the main cause. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.

If you can see any of these, it’s time to have the joints looked at:

  • Cement or filler used on old window joints that has cracked
  • Gaps where the frame meets the masonry
  • Mastic round period door frames that has failed
  • Old sand mastic that has cracked, crumbled or fallen out

In the older streets around The church of St Michael and All Angels, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What your quote should include

  • Who turns up on the day
  • When the joint can take water or movement
  • How the surfaces are prepared before sealing
  • What insurance they hold

How to choose a mastic man

What happens on the day

All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours per window, depending on the condition of the joints. Somewhere like Balls Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. Each surround is checked first.
  2. We rake out the old mastic and clean the joint.
  3. Large voids are packed out.
  4. New sand mastic is applied and shaped by hand.
  5. We finish the mastic to a tidy line.

Advice

Surface by surface

Sash and case windows

A sash window’s box frame sits in the masonry opening. The gap round it is pointed with sand mastic.

Tenement and terrace windows

Upper-floor windows need access planning. Tell us the height and we’ll confirm what’s needed.

When something else is needed

We’d rather tell you now than do work that will not last, so these are the limits:

  • Crumbling stone or brickwork round the window
  • Broken panes
  • Sash cords, weights and draught-proofing of the sashes

Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly before booking.

Joints and surfaces we work on
