About our sand mastic in Gowkshill
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted, so ask us before you decorate. Common call-outs are for weathered mastic on the most exposed windows and draughts and rain around sash boxes, on tenement windows, sash and case windows and stone surrounds.
In and around a place like Gowkshill, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
You are covered for a year from the day we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

Why act early in Gowkshill
Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it, and the new mastic is traditionally left unpainted. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
What we do, step by step
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours for a single window, longer for several. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints

Gowkshill homes and the weather
With historic houses such as Melville Castle (about 3 miles north-west) nearby, there’s older building stock in the area around Gowkshill as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
If you let a flat or house near Newtongrange station, any sash windows need sound mastic to keep draughts and rain out. If you look after a building such as Newbattle Community High School, the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Newtongrange Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
