Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Leave the new mastic unpainted
  • Avoid patching sand mastic with silicone
  • Ask the planning authority about consent for listed or conservation-area homes
  • Keep sills and gutters clear so water drains away

Check the mastic when you check the paintwork. Small cracks are easier to deal with early.

Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.

Sand mastic in Kilmarnock

If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. If you are dealing with cement or filler used on old window joints that has cracked and mastic dropping out of the joint, we can help, whatever the surface.

In a town like Kilmarnock, plenty of homes have harled (roughcast) walls, and the joint between a frame and rough harling needs a sealant that can grip and flex. A thin bead that hasn’t been worked into the surface soon lets water behind it.

A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

Kilmarnock homes and the weather

Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Historic houses like Carnell Estate (about 4.4 miles south-east) are a reminder that the area around Kilmarnock has older buildings as well as new. 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 Henderson Church Of Scotland, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Kilmarnock station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.

DIY sealant or a professional job?

A careful DIYer can reseal a simple joint, 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’s fine. We cut it out and start again, so tell us about it when you ask for a quote.

How we quote for sand mastic

  • How much old sealant there is and how hard it is to remove
  • The amount of work
  • The number of rooms or windows
  • When we can work, for business premises

Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

  • Any previous sealing or DIY work
  • Photos by email, if that’s easy
