Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Check the mastic once a year
- Wash the frames with mild soapy water
- Clear any debris from frame drain holes
- Avoid blasting the frames with a pressure washer
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
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 it pays to reseal before that happens.
How we handle window mastic in Auldgirth
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. Common call-outs are for old mastic that has gone black or come away and draughts coming in around windows and doors, across patio & French doors, window sills and aluminium frames.
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.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Do you need window mastic in Auldgirth?
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
Look out for these signs:
- Gaps where the sill meets the wall
- Whistling draughts around closed windows
- Rain getting in at the frame or under the sill
- Cracked or shrunken mastic around the frame
Around Auldgirth, as everywhere, window mastic is only as good as the preparation behind it.

What affects the cost of window mastic
You will get a clear quote before any work starts. It takes into account:
- The old material and how stubborn it is
- How many areas need sealing
- Mould in or behind the old joints
- The amount of work
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What we need to know
You don’t need to know the technical terms. It helps if you can tell us:
- How many joints, rooms or windows are involved
- If someone has resealed it before
- What’s wrong with the joints now
- Where the property is
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.
Auldgirth: your questions answered
Is window mastic in Auldgirth guaranteed?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Can you do window mastic in Auldgirth?
Yes. We work across all of Scotland, and Auldgirth 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 price.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses and we’re fully insured.
Will resealing my frames help with draughts?
Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that’s a different fix, and we’ll say so.
What should I tell you?
Tell us what needs doing and where, with photos by email if possible. We will ask anything else we need to know.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Is it OK to seal over old sealant?
No, it will not last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
What we do, step by step
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. Most jobs take a few hours for a handful of frames, longer for a whole house. Outside jobs in Auldgirth need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can
- Let us know if you’ve seen damp or leaks

Composite doors
Front doors take the weather head on. We pay most attention there.
Windows and doors in Auldgirth
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Whether the job is in Auldgirth itself or nearby, the right material for each joint matters as much as a neat finish.

Why act early in Auldgirth
Resealing frames is a short job: the visit takes a few hours for a few frames, or a day or more for a whole house. Wait for damp to appear and there may be plaster and decorating to sort out too. 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.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk and we will give you an honest view and a quote.
