Common problems we fix in Halleaths
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
Look out for these signs:
- Damp patches on the reveal after heavy rain
- Cracked internal joints between frame and plaster
- Gaps where the sill meets the wall
- Draughts coming in around windows and doors
For site and facilities teams at buildings such as Lockerbie Academy, the mastic around its windows and doors needs looking after like any other building’s.

Window mastic in Halleaths
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty. Where the air is getting in through the window itself, we’ll say so. We work on timber windows & doors, uPVC windows and patio & French doors, and the jobs we see most are sealant in the wrong colour for the frame and cracked or shrunken mastic around the frame.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
You get a 12-month guarantee, the same in Halleaths as everywhere else we work.

Should I try it myself first?
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 fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Leave it or put it right?
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Window mastic in Halleaths: local notes
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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
In the older streets around Lochmaben Parish Church, the joint between an old wall and a newer frame is normally the first place rain gets in. Letting a property close to Lockerbie station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Check the mastic once a year
- Wipe condensation off the frames
- Repaint timber before it’s bare
- Keep drainage slots and sill grooves clear
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just email us at info@mrmastic.co.uk.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
The process
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours for a few frames, or a day or more for a whole house from start to finish. Outdoor work around Halleaths depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry, 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.
Preparing for the visit
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints
- Let us know about stairs, lifts or work at height

What information do you need?

Can you seal over the old sealant?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Are you fully insured?
Yes, we’re fully insured.

Yes, in most cases. Tell us the frame colour when you get in touch and we’ll match it as closely as we can.
Is the new sealant paintable?
It depends on the sealant. Silicone isn’t paintable, but some hybrid sealants are. Tell us if you are decorating and we will choose accordingly.
Can landlords and businesses book you?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels in Halleaths.
Different surfaces, different methods
Composite doors
A composite door normally sits in a plastic outer frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. If we find rot, we’ll tell you before going ahead, as that is a job for a joiner.
