Window mastic for homes and businesses in Cottown
Homes in Cottown have every kind of window: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. Typical jobs include black, perished sealant on frames and cold air getting in at the frame edge, on composite doors, patio & French doors and timber windows & doors.
Outdoor sealant needs a dry surface, so window work around Cottown is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
The work is covered for a year after we finish. If anything isn’t right with it, send an email to info@mrmastic.co.uk.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Repaint timber before it’s bare
- Don’t aim a pressure washer at the joints
- Avoid harsh chemicals near the mastic
- Use gentle cleaners on frames and sealant
Silicone cannot generally be painted, so if you are planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
Frames and glazing around Cottown
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. Historic houses like Leith Hall (about 3 miles north-east) are a reminder that the area around Cottown has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Leith Hall, about 3 miles north-east, is one of the historic houses in the wider area around Cottown, and older homes nearby need a sealant that suits their walls.

Surface by surface
Composite doors
Front doors take the weather head on, and the top and bottom corners tend to fail first. We pay most attention there.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
What affects the cost of window mastic
Your quote is based on your job. We look at:
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
- How many areas need sealing
- Access and height
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- Access, such as stairs, a lift or height
- Whether it’s a home or a business
- The address or postcode of the job
- Pictures of the joints, sent by email
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.
Common problems we fix in Cottown
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
People generally contact us after spotting one of these:
- Whistling draughts around closed windows
- Gaps where the sill meets the wall
- White mastic on grey or black frames
- Water coming in at the bottom corners of a door
In and around Cottown, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Why deal with it now?
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.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Common questions in Cottown
Is Cottown in your area for window mastic?
Yes, Cottown is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Is window mastic in Cottown guaranteed?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can you get sealant to suit coloured frames?
Yes, in most cases. Tell us the frame colour when you get in touch and we will use the nearest match.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
When is the sealant fully cured?
It depends on the product. Before we leave, we will tell you the cure time.
What information do you need?
A short description and the location, with pictures by email if possible. If we need more, we will ask.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages.
The process
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of frames, longer for a whole house. For a place like Cottown, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints
- Tell us about any water getting in
