About our sand mastic in Barnhill
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. Common call-outs are for gaps round a timber door in stone or brick and modern sealant on a period surround, on stone surrounds, period & listed homes and brick reveals.
In a Scottish city, many flats have windows two, three or four floors up, so the mastic outside can go unchecked for years. Access is the first thing to plan for a job in Barnhill.
We stand behind the work with a 12-month guarantee, so you’re covered after we’ve gone.

When to call us in Barnhill
Over the years, sand mastic weathers. It dries out, cracks and loses its grip from the frame or the masonry.
Keep an eye out for these signs:
- Mastic that needs renewing before redecorating
- Crumbling sand mastic round a window
- Cement or filler used on old window joints that has cracked
- Draughts and rain around sash boxes
For site and facilities teams at buildings such as Monifieth High School, the mastic around its windows and doors needs looking after like any other building’s.

How to look after the new joints
After the cure time, these simple habits help:
- Get any rot dealt with first
- Check with your local planning authority if your home is listed
- Go gently near the mastic when preparing windows
- Inspect the joints round the windows every year or so
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.

Barnhill homes and the weather
Barnhill is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
If you let a flat or house near Balmossie station, any sash windows need sound mastic to keep draughts and rain out. For an older house near a landmark such as St Margaret's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What affects the quote in Barnhill
There’s no set price list, because no two jobs are the same. What we look at:
- Access and height
- The type of sealant required
- Any mould that needs treating
- Any working-time requirements on site
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- How we’d reach the joints
- A few pictures by email, if you can
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes anything from a few hours to a full day, depending on how many windows. Parking in city streets around Barnhill can be tight or controlled, so it helps to know about permits or nearby bays. If you are in a flat, let us know how we get in at the street door.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
How to prepare
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints
- Keep pets and children clear of the area while we work
Getting a quote
