Sand mastic for Laxdale homes and businesses

Sand mastic in Laxdale

Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. Common call-outs are for failed mastic on an exposed elevation and mastic dropping out of the joint, across stone surrounds, tenement windows and brick reveals.

Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.

Each job carries a 12-month guarantee.

What we cannot put right

In fairness, there are a few things sealant won’t fix:

  • Sashes that rattle, stick or will not open
  • Rotten sashes, sills or window boxes (a joiner’s job)
  • Cracked or broken glass

If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before booking.

Quotes for sand mastic in Laxdale

There’s no set price list, because jobs vary so much. What we look at:

  • Mould in or behind the old joints
  • The old material and how stubborn it is
  • How many rooms, windows or areas are involved
  • Access and height

Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.

What to tell us for a quote

There’s no need for technical detail. It helps if you can tell us:

  • The problem you’ve noticed
  • If someone has resealed it before
  • The rough size of the job
  • A few pictures by email, if you can

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.

Laxdale homes and the weather

Laxdale is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Island weather, with its wind and salt spray, is tough on the mastic around older windows and doors.

Whether the job is in Laxdale itself or nearby, the right material for each joint matters as much as a neat finish. Around Laxdale, as everywhere, sand mastic is only as good as the preparation behind it.

How the job changes by surface

Brick reveals

Brick reveals round timber windows are often pointed with sand mastic. It suits older brickwork.

Timber door frames

Sand mastic is used round timber door frames too. The method is the same as for windows.

What happens on the day

Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours per window, depending on the condition of the joints. Outdoor work around Laxdale depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.

  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.

Getting ready for the visit

  • Clear items away from the joints we’re working on
  • Let us know about earlier repairs to the joints
  • Plan for the work area to be out of bounds to pets and children

Related advice

Looking after it afterwards

Looking after new joints is easy, and it makes a real difference:

  • Find out about consent before window work on a listed home
  • Keep sills and gutters clear so water drains away
  • Go gently near the mastic when preparing windows
  • Check the mastic when you check the paintwork

Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.

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

Work for landlords, hotels and businesses

Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured for the work.

We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.

Why it’s worth doing now in Laxdale

New sash windows are a major, costly change and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Around Laxdale, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, email us at info@mrmastic.co.uk and we will give you an honest view and a quote.
