Sand mastic in Gorthleck, done properly
Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted, so ask us before you decorate. Typical jobs include mastic that needs renewing before redecorating and modern sealant on a period surround, across brick reveals, timber door frames and tenement windows.
In and around a place like Gorthleck, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
Whatever the size of the job, you get the same 12-month guarantee.

Aftercare tips
So the new joints stay in good condition:
- Avoid heavy scraping on the mastic joint
- Inspect the joints round the windows every year or so
- Do not paint over the new mastic
- Keep modern sealant off the mastic
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.

What affects the quote in Gorthleck
We do not publish a price list. What we look at:
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- Whether there’s mould to deal with
- How many rooms, windows or areas are involved
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

- What’s wrong with the joints now
- Photos by email, if that’s easy

Frames and glazing around Gorthleck
Historic houses like Boleskine House (about 2.1 miles north-west) are a reminder that the area around Gorthleck has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Around Gorthleck, as everywhere, sand mastic is only as good as the preparation behind it.

Landlord and commercial work in Gorthleck

From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Leave it or put it right?
Draughts round a sash window aren’t always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. In an older home around Gorthleck, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
What you pay reflects the work, not guesswork. That is why we ask a few questions first.
