About our window mastic in Madderty
Whether it’s one leaking patio door or every frame on the house, you’ll get a clear quote before any work starts. Just email us at info@mrmastic.co.uk and tell us how many frames there are and how they’re reached for window mastic in Madderty. We work on composite doors, window sills and patio & French doors, and common reasons people get in touch are black, perished sealant on frames and white mastic on grey or black frames.
Mastic can only go onto a dry joint, so outside work in Madderty depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

What we’re called out for in Madderty
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, and it lets go sooner than it should.
Any of these means the joints need attention:
- Gaps left after new windows were fitted
- Leaking joints at the ends of sills
- Black, perished sealant on frames
- Sealant in the wrong colour for the frame
Whether the job is in Madderty itself or nearby, the right material for each joint matters as much as a neat finish.
What your quote should include

Aftercare tips
Good habits help new joints last longer. Our tips:
- Check the mastic once a year
- Clean frames with a soft cloth and soapy water
- Make sure the drainage slots are not blocked
- Paint up to the joint, not over it
Keep the new mastic undisturbed while it cures, for as long as we advise. Do not point a pressure washer at the joints.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
Common questions in Madderty
Is window mastic in Madderty guaranteed?
All our work, in Madderty and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Do you cover smaller places like Madderty?
Yes. Madderty is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will tell you what we are using.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Can I paint over the new sealant?
That depends on the product. Some hybrid sealants can be painted; silicone can’t. Mention any painting plans before any work starts.
Do you work on first-floor windows?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote and we will plan for it.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
Can tenants book the work?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
What sealant work can’t fix
In fairness, some problems need a different trade:
- A sash or casement that won’t close properly
- Worn gaskets, brush seals or a door that has dropped
- Penetrating damp from a failed cavity tray or render
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly before you book.
Joints and surfaces we work on
- uPVC windows
- Window sills
- Composite doors
- Patio & French doors
- Timber windows & doors
- Aluminium frames
Surface by surface
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. Those corners get the most care.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.
What we do, step by step
You do not need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes a few hours for a handful of frames, longer for a whole house in most cases. For a place like Madderty, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Clear the area around the work
- Let us know about earlier repairs to the joints

Madderty homes and the weather
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
Around Madderty, as everywhere, window mastic is only as good as the preparation behind it.

Why it’s worth doing now in Madderty
Failed mastic is not a reason to replace sound windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we will say so. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
