Aftercare tips

A little care helps the new joints last. We recommend:

  • Ask a joiner to look at soft timber first
  • Ask us before painting near the mastic
  • Check with your local planning authority if your home is listed
  • Look over the window mastic once a year

Leave the new mastic alone while it firms up. It skins over quickly but needs longer to fully harden.

Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall, so renewing it early is worth it.

Sand mastic in Church Crookham

Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. We work on tenement windows, timber door frames and sash and case windows, and the jobs we see most are crumbling sand mastic round a window and open joints round the window box.

Somewhere as small as Church Crookham, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.

Your job is guaranteed for a year, as with all our work.

Landlords, agents and businesses in Church Crookham

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.

We work for landlords and agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.

DIY sealant or a professional job?

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

How the visit works

At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours per window, depending on the condition of the joints, depending on the size of the job. Somewhere as small as Church Crookham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We check each window surround and the condition of the joint.
  2. We rake out the old mastic and clean the joint.
  3. We fill deep gaps so the new mastic is not too thick.
  4. We point the joint with sand mastic by hand.
  5. We finish the mastic to a tidy line.

Preparing for the visit

  • Mention any parking rules near the property
  • Tell us about access, such as stairs, a lift or high-level joints
  • Tell us about any water getting in

Sand mastic in Church Crookham: local notes

London and the South East are among the drier parts 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 Farnham Castle (about 3.5 miles south) nearby, there’s older building stock in the area around Church Crookham as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.

If you live in an older home near Fleet Spiritualist Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Velmead Junior School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
