About our sand mastic in Dornock

Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we’ll talk through which suits your home. Common call-outs are for mastic worn away on windows facing the weather and gaps where the frame meets the masonry, across period & listed homes, timber door frames and brick reveals.

Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Why it’s worth doing now in Dornock

New mastic over crumbling mastic will not hold. Raking out and preparing the joint gives it a sound base so the new work lasts. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.

Doing several joints on one visit generally makes better use of the time than several visits. You’ll get one clear quote for the whole job.

The process

We keep the work tidy and contained to the area we’re working on. The job generally takes anything from a few hours to a full day, depending on how many windows. Around Dornock, distance and access matter more than parking. Let us know how to find you and how to reach the joints.

  1. First, we look at the surrounds with you and agree what needs doing.
  2. We rake out the old mastic and clean the joint.
  3. Deep voids are packed so the mastic is the right thickness.
  4. Sand mastic is mixed and applied by hand, then shaped to the joint.
  5. The mastic is finished to sit tidily against the stone or brick.

How to prepare

  • Let us know about stairs, lifts or work at height
  • Move anything stored near the joints
  • Tell us about any previous sealing or DIY attempts

What the job involves on each surface

Tenement and terrace windows

Tenements and terraces often have many sash windows with ageing mastic. We can do one window or several.

Brick reveals

Gaps between frame and brick let in rain and draughts. New mastic seals the gap.

When it isn’t the sealant

We will always be straight with you, so here’s what sealant cannot fix:

  • Sash cords, weights and draught-proofing of the sashes
  • Damaged stone surrounds
  • Decisions on consent for listed homes

If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.

Surfaces we seal

  • Brick reveals
  • Sash and case windows
  • Tenement windows
  • Timber door frames
  • Period & listed homes
  • Stone surrounds

Dornock homes and the weather

Dornock is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.

For landlords with property near Annan station, cracked sand mastic around sash windows lets in the draughts tenants complain about. In the older streets around Dornock Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Annan Academy? Then larger buildings have plenty of frames, and the mastic around each one ages.

Aftercare tips

Simple care keeps the joints in good condition. We recommend:

  • Find out about consent before window work on a listed home
  • Do not paint over the new mastic
  • Renew mastic before redecorating the windows
  • Inspect the joints round the windows every year or so

Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.

Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
