Dunblane Sand Mastic
Window and door surrounds in Dunblane need attention? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- Draughty sash windows at the surround
- Mastic that needs renewing before redecorating
- Gaps between timber frames and stone or brick
How we handle sand mastic in Dunblane
Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted, so ask us before you decorate. If you have silicone on a period window that looks wrong and mastic dropping out of the joint, we can put it right.
Mastic can only go onto a dry joint, so outside work in Dunblane depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
All of our work is guaranteed for twelve months.

What we’re called out for in Dunblane
Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
Signs it’s time to call us include:
- Crumbling sand mastic round a window
- Mastic that needs renewing before redecorating
- Mastic round period door frames that has failed
- Failed mastic on an exposed elevation
In and around Dunblane, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

Aftercare tips
After the cure time, these simple habits help:
- Check with your local planning authority if your home is listed
- Get any rot dealt with first
- Take care around the mastic when scraping paint
- Do not run silicone over sand mastic
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
What we do, step by step
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for a single window, longer for several. Somewhere like Dunblane may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Mention any tricky access
- Move anything stored near the joints

Dunblane homes and the weather
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Rented homes near Dunblane station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

Dunblane questions
I let a flat near Dunblane station. Can you help?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Is Dunblane within the area you cover?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Is consent needed for window work on a listed home?
Yes, it’s worth checking. Your local planning authority can say if consent is needed for listed or conservation-area properties.
How long will you be here?
Most jobs take anything from a few hours to a full day, depending on how many windows, including preparation and clearing up. Your quote will say how long we expect yours to take.
What exactly is sand mastic?
It’s sand mixed with a linseed-oil-based binder for the joint between timber frames and masonry.
Are you insured?
Yes. We are fully insured for domestic and commercial work.
Can you seal over the old sealant?
No. We remove every bit of old sealant first.
Is it possible to paint over sand mastic?
The usual advice is to leave sand mastic unpainted. If you are redecorating the window, ask us first and we’ll talk you through it.
What happens if it’s left?
New mastic over crumbling mastic will not hold. Raking out and preparing the joint gives it a sound base so the new mastic stays put. 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.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.
