Your questions about window mastic in Steelend
Can you do window mastic in Steelend?
Yes. Our work covers the whole of Scotland, and Steelend is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Is Steelend within the area you cover?
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.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we’re using and why.
Do you seal inside as well as outside?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
Do you guarantee window mastic?
Yes. Each job is covered for 12 months, inside or out.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Can landlords and businesses book you?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels across Fife.
How long does it take to reseal the windows on a house?
That depends on the number of frames, how they’re reached and the state of the old mastic. We’ll tell you how long your job needs when we quote.
Window mastic in Steelend, done properly
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. If you’re dealing with gaps left after new windows were fitted and cold air getting in at the frame edge, we can help, on patio & French doors, aluminium frames and composite doors alike.
Mastic can only go onto a dry joint, so outside work in Steelend depends on the weather. Tell us about access to all the windows and doors, upstairs included.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

The process
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes anything from an hour or two to a full day, depending on how many frames there are. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- 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 indoor joints, keep the area dry beforehand if you can
- Tell us if parking is tricky
- For business premises, tell us about site rules or sign-in

What else we do in Steelend
For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Frames and glazing around Steelend
Historic houses like Pittencrieff House (about 4.3 miles south-east) are a reminder that the area around Steelend has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Pittencrieff House, about 4.3 miles south-east, is one of the historic houses in the wider area around Steelend, and older homes nearby need a sealant that suits their walls. Rented homes near Dunfermline City station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- If it’s domestic, commercial or a hotel
- The address or postcode of the job
- How we’d reach the joints

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 add photos by email if you can.
Aftercare tips
A little care helps the new joints last. We recommend:
- Ventilate rooms so frames do not stay wet inside
- Walk round the house once a year and look at the joints
- Paint up to the joint, not over it
- Avoid harsh chemicals near the mastic
Keep the new mastic undisturbed while it cures, for as long as we advise. Do not point a pressure washer at the joints.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.
When something else is needed
A few problems are outside what sealant work can do:
- A sash or casement that will not close properly
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A frame that has rotted at the joint
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before booking.

- Aluminium frames

How the job changes by surface
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. They’re cut out and resealed with exterior sealant.
Aluminium frames
Coated aluminium needs a compatible sealant. Neutral-cure sealant is the safe choice.
