What the job involves on each surface
Window sills
Where a sill meets brick or render, the ends often crack first. We reseal them so rain can’t run into the wall.
Composite doors
Front doors take the weather head on, and the top and bottom corners tend to fail first. We pay most attention there.
Window mastic in Balgowan
Frames and walls don’t move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. If you’re dealing with cracked sealant at the sill ends and rain getting in at the frame or under the sill, we can put it right, whatever the surface.
In a Scottish city, many flats have windows two, three or four floors up, where failing mastic is easy to miss. For a flat in Balgowan, access is the first thing to plan.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Leave it or put it right?
Failed mastic isn’t a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. If we find failed glass units or worn seals, we’ll tell you. In a Scottish city tenement, failed sealant affects more than one flat: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
What you get with us
- Trusted Arbo and Everbuild sealants
- ARBOMaster approved applicator
- A choice of colours where the product allows
- Anti-fungal silicone where joints get wet
What we do, step by step
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes most of a day for a typical house, less for a few frames. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. For a job in Balgowan, tell us the floor, how the door entry system works and where we can park nearby.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height

Landlords, agents and businesses in Balgowan
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together.
What we can’t put right
A few problems are outside what sealant work can do:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Draughts through the window seals rather than the frame
- Damp coming through the wall itself rather than the frame joint
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer before you book.

Common questions in Balgowan
Can you help a landlord with a rental near Dundee station?
Yes, we work for landlords and agents. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before any work starts.
Is window mastic in a coastal place like Balgowan any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Will new mastic stop draughts?
If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that’s a different fix, and we will say so.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
When is the sealant fully cured?
That depends on the sealant used, so follow the cure time we give you when we finish.
How much does window mastic cost in Balgowan?
Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.
DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Looking after it afterwards
Looking after new joints is easy:
- Make sure the drainage slots are not blocked
- Keep timber frames painted
- Avoid blasting the frames with a pressure washer
- Check the mastic once a year
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak, and if anything looks wrong, just email us at info@mrmastic.co.uk.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
Frames and glazing around Balgowan
Balgowan is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
If you live in an older home near St Luke's Episcopal Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Letting a property close to Dundee station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For site and facilities teams at buildings such as Baldragon Academy, the mastic around its windows and doors needs looking after like any other building’s.
