- A door that needs adjusting, rehanging or new seals
- A frame that has rotted at the joint
- A failed sealed unit that has misted up
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before booking.

Window mastic in Ashkirk, done properly
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. If you are dealing with cracked internal joints between frame and plaster and sealant in the wrong colour for the frame, we can put it right, on timber windows & doors, aluminium frames and uPVC windows alike.
Outdoor sealant needs a dry surface, so window work around Ashkirk is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Different surfaces, different methods
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so they get particular care.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We will tell you which suits your home.
How the visit works
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a morning for a couple of windows and a door. Around Ashkirk, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Getting ready for the visit
- Tell us if parking is tricky
- Mention any sign-in or site rules at work premises
- Where the joints are inside, avoid wetting them before we arrive

Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Ashkirk homes and the weather
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
Homes close to Ashkirk Parish Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Ashkirk questions
Is there a guarantee on window mastic in Ashkirk?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Will you come out to Ashkirk?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Will resealing my frames help with draughts?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
Do you work for letting agents?
Yes, we do. Domestic, commercial and hotel work are all part of what we do.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Do you have sealant for grey or black windows?
Yes, in most cases. Mention the frame colour when you ask for a quote and we’ll use the nearest match.
Other services in Ashkirk
When to call us in Ashkirk
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
People generally contact us when they notice something like this:
- Draughty joints inside around the window
- Untidy mastic left by window fitters
- Hard, cracked sealant around windows
- Damp patches on the reveal after heavy rain
Around Ashkirk, as everywhere, window mastic is only as good as the preparation behind it.
Before booking anyone

- What insurance they hold
- Which colour the sealant will be
- Who does the work, and how experienced they are
Why it’s worth doing now in Ashkirk
If you’re painting or rendering, reseal at the same time. Fresh joints finish the job neatly. 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.
What it costs depends on the amount of work, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.
Why Ashkirk customers choose us
- More than 20 years in sealant work
- We never seal over old sealant
- Colour picked to suit the job
- Anti-fungal sanitary silicone in wet areas
