About our window mastic in Montrose
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. If you have black, perished sealant on frames and rain getting in at the frame or under the sill, we can help.
In a town like Montrose, stone-built older streets generally sit alongside harled houses and newer estates, so windows range from sash and case in older buildings to uPVC on newer homes. Each needs the right sealant against the right wall.
All our work comes with our one-year guarantee, wherever you are in Aberdeenshire.

What we do, step by step
We bring everything the job needs with us. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours for a handful of frames, longer for a whole house. Parking around Montrose is rarely difficult, though older streets in the centre can be tight. For flats, mention the shared stair or door entry system.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- 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
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in

Frames and glazing around Montrose
Montrose is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Schools such as Montrose Academy are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
Montrose is about 26 miles north-east of Dundee, in Aberdeenshire. Whether you’re in the middle of Montrose or further out, we cover window mastic for every kind of property. We cover 161 towns and villages across Aberdeenshire. Dundee is on our list too, around 26 miles away.

What the job involves on each surface
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. We seal those with a sealant suited to masonry.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We’ll tell you which suits your home.
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too in Montrose and across Aberdeenshire. Several sites can be quoted together, and we’re fully insured.
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Quotes for window mastic in Montrose
The quote reflects the job in front of us. We look at:
- How much old sealant there is and how hard it is to remove
- The product the joint needs
- How easy the joints are to reach
- Mould in or behind the old joints
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and give you a clear price before work begins.
What we need to know
To make quoting easier, please include:
- Where the job is, and your postcode
- If someone has resealed it before
- Photos by email, if that’s easy
- Any access issues, like height or stairs
Getting a quote is simple: let us know what needs doing and where and its rough size. A few pictures by email make the job easier to understand, and we’ll take it from there.
Why act early in Montrose
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. For landlords in Montrose, damp and leaks can fall under the Repairing Standard. Replacing failed sealant early is simpler than dealing with a complaint.
A failed joint rarely gets cheaper to fix by waiting. 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.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Montrose: your questions answered
Do you work for landlords with property near Montrose station?
Yes, rental work is part of what we do. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Is Montrose in your area for window mastic?
Yes, Montrose is within the area we cover. We work across all of Scotland. 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 guarantee window mastic?
Yes, with our one-year guarantee. Keeping drainage clear and checking the joints yearly helps them last.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
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.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Where is Mr Mastic based?
We’re a Crawley-based firm. We work across South East England, London and Scotland.
When to call us in Montrose
Mastic ages in the weather. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
People normally contact us after spotting something like this:
- Cracked sealant at the sill ends
- Cold air getting in at the frame edge
- Rain getting in at the frame or under the sill
- Gaps between the frame and the inside reveal
Letting a property close to Montrose station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
Questions to ask before you book
- Which colour the sealant will be
- What product goes in the joint
- Is VAT in the price?
- How long to leave it before use
