When to call us in Dalbeattie
Over the years, sand mastic weathers. It hardens, cracks and starts to come away on the stone or timber.
The problems people generally mention when they call include:
- Silicone on a period window that looks wrong
- Draughts and rain around sash boxes
- Cracked mastic round a front door frame
- Old sand mastic that has cracked, crumbled or fallen out
If you live in an older home near Dalbeattie Park Church, the joint between an old wall and a newer frame is usually the first place rain gets in.

Sand mastic in Dalbeattie
Silicone on a period window often looks wrong and is not always the right material. Sand mastic is the traditional choice, and we can replace one with the other. We work on period & listed homes, sash and case windows and stone surrounds, and common reasons people get in touch are silicone on a period window that looks wrong and mastic that needs renewing before redecorating.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
All our work is covered by a one-year guarantee.

What else we do in Dalbeattie

Sash and case windows
On a sash window, the mastic joint shows on the outside so we finish it carefully.

Frames and glazing around Dalbeattie
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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
If you look after a building such as Dalbeattie High School, its window and door frames need their mastic kept sound, just like a home’s.

Landlords, agents and businesses in Dalbeattie

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Why act early in Dalbeattie
Not every filler suits an old window surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. In a place like Dalbeattie, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

What we do, step by step
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take a few hours for a single window, longer for several. Somewhere like Dalbeattie may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- First we agree which joints need doing.
- 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.
Before we arrive
- Mention any tricky access
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in
