Sand mastic for sash & case windows in Dingwall, Highland
We cover Dingwall for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Weathered mastic on the most exposed windows
- Open joints round the window box
- Window mastic to renew ahead of painting
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
How we handle sand mastic in Dingwall
Across Dingwall, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand, finished to suit the masonry. We are often asked to deal with cracked mastic round a front door frame and draughts and rain around sash boxes, across stone surrounds, period & listed homes and timber door frames.
Outdoor sealant needs a dry surface, so window work around Dingwall is planned around the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
You are covered for a year from the day we finish. If anything is not right with it, drop us a line at info@mrmastic.co.uk.

How it works
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a single window, longer for several. Outdoor work around Dingwall depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in
- For indoor joints, keep the area dry beforehand if you can

Aftercare tips
A little care helps the new joints last. We recommend:
- Get any rot dealt with first
- Make sure water runs off the sill
- Don’t paint over the new mastic
- Look over the window mastic once a year
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.
What happens if it’s left?
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. Around Dingwall, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Common problems we fix in Dingwall
Paint, silicone or cement used over old mastic causes problems. They do not move with the timber, and they normally need raking out.
Signs it’s time to call us include:
- Mastic round period door frames that has failed
- Old sand mastic that has cracked, crumbled or fallen out
- Silicone on a period window that looks wrong
- Weathered mastic on the most exposed windows
In the older streets around St Lawrence's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Dingwall: your questions answered
Can you help a landlord with a rental near Dingwall station?
Yes, we work for landlords and agents. Just send an email to info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear quote.
Does the coastal weather in Dingwall affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
How long will you be here?
A typical job takes a few hours per window, depending on the condition of the joints, including preparation and clearing up. Your quote will say how long we expect yours to take.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.
Is it possible to paint over sand mastic?
It’s traditionally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
What sand mastic looks like in Dingwall
Dingwall is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces 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.
Managing a site like Dingwall Academy? Then the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Dingwall station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.
