FAQs for Walkerburn
Can you do window mastic in Walkerburn?
Yes. We work across all of Scotland, and Walkerburn is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
Is Walkerburn within the area you cover?
Yes, Walkerburn is covered. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you match the sealant to my frames?
Yes. We can use white, brown, anthracite grey, black or clear.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Do you work on first-floor windows?
Generally, yes. Access is planned before any work starts.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
How we handle window mastic in Walkerburn
Colour matters on a frame. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. We work on window sills, composite doors and patio & French doors, and the jobs we see most are draughty joints inside around the window and damp patches on the reveal after heavy rain.
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.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
For landlords and businesses
We also work for property managers and facilities teams. Several sites can go on one quote.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
When it isn’t the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- A sash or casement that won’t close properly
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Soft or decayed wood in the frame
If you’re not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Composite doors
- Patio & French doors
- Window sills
- Timber windows & doors
- Aluminium frames
- uPVC windows
Leave it or put it right?
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. 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 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 any work starts.

Walkerburn 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.
For an older house near a landmark such as Walkerburn Parish Church, the joint between an old wall and a newer frame is usually the first place rain gets in.

The process
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for a few frames, or a day or more for a whole house, and the area is left clean. For a place like Walkerburn, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive
- Mention any tricky access

When to call us in Walkerburn
Mastic ages in the weather. Sunlight dries the surface out, until it loses its stretch and starts to crack.
Any of these means the joints need attention:
- Leaking joints at the ends of sills
- Water coming in at the bottom corners of a door
- Rushed sealant from a window installation
- Mastic that has split away from the wall
In and around Walkerburn, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
What your quote should include
- Who does the work, and how experienced they are
- The length of the guarantee
- Whether the sealant suits the joint
- When the joint can take water or movement
