What affects the quote in Lochee
The price is agreed before any work begins. It takes into account:
- The type of sealant required
- Mould in or behind the old joints
- When we can work, for business premises
- Access and height
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.
What to tell us for a quote
When you contact us, it’s useful to know:
- Photos by email, if that is easy

Window mastic for homes and businesses in Lochee
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that can’t move properly, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. If you have gaps between the frame and the inside reveal and water coming in at the bottom corners of a door, we can help, whatever the surface.
Tenement flats in Scotland’s cities often have windows high above the street, where failing mastic is easy to miss. Access is the first thing to plan for a job in Lochee, and in a tenement the outside of the building may be a shared repair.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

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, then guaranteed for a year.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Leave it or put it right?
Not every sealant suits a window. Interior caulk and bathroom silicone aren’t made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. Private landlords in Lochee must meet the Repairing Standard, and damp or leaks can fall short of it, so failed sealant is best replaced before it becomes a complaint.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

Lochee homes and the weather
Lochee is within about 2 miles of 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 sound outside sealant is part of that.
Managing a site like Menzieshill High School? Then larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near Lochee Baptist Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

FAQs for Lochee
Does the coastal weather in Lochee affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can you help a landlord with a rental near Dundee station?
Yes, landlords and agents are among the people we work for. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Do you have insurance?
Yes. Full insurance covers our work.
How many windows can you do in a day?
The work takes a morning for a couple of windows and a door. Access and the amount of old mastic make the biggest difference.
Can new window sealant be painted?
That depends on the product. Some hybrid sealants can be painted; silicone cannot. Tell us if you’re decorating and we will choose accordingly.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
What happens on the day
There isn’t much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours for a handful of frames, longer for a whole house, including the tidy-up. In a city area like Lochee, parking may be by permit or pay-and-display, so tell us what’s nearby. For flats, mention the door entry system and any shared-stair arrangements.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- 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
- Where the joints are inside, avoid wetting them before we arrive
- Let us know if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children

What we’re called out for in Lochee
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. A sealant that can’t keep up eventually tears.
If you can see any of these, it’s time to have the joints looked at:
- Cracked or shrunken mastic around the frame
- Damp patches on the reveal after heavy rain
- Draughty joints inside around the window
- Black, perished sealant on frames
Rented homes near Dundee station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Aftercare tips
A little care helps the new joints last. We recommend:
- Make sure the drainage slots aren’t blocked
- Paint up to the joint, not over it
- Keep solvents and bleach off the sealant
- Keep jet washers away from the mastic
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
