Window mastic in Strathmartine
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through and quietens the whistle on windy days. Where the air is getting in through the window itself, we will say so. We work on composite doors, aluminium frames and patio & French doors, and people most often call us about gaps between the frame and the inside reveal and rushed sealant from a window installation.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill.
All our work comes with a 12-month guarantee, wherever you are in Dundee.

For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- A door that needs adjusting, rehanging or new seals
- Condensation trapped between the panes
- Faulty window hardware
If you are not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.

What else we do in Strathmartine
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Avoid blasting the frames with a pressure washer
- Repaint timber before it’s bare
- Use gentle cleaners on frames and sealant
- Walk round the house once a year and look at the joints
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 drop us a line at info@mrmastic.co.uk.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.
What we do, step by step
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours for a few frames, or a day or more for a whole house. 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.
- 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.
Before we arrive
- Keep children and pets away from the work area
- Tell us about any water getting in
- Mention any tricky access

What the job involves on each surface
Patio & French doors
Water at the foot of a door frame is not always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
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, and the work is guaranteed for a year.
Why deal with it now?
Running fresh sealant over the old joint is tempting, but it won’t grip old, dirty sealant. It soon lifts and the leak carries on behind it. The old mastic has to come out. In an older home around Strathmartine, damp from a failed joint can get into timber and plaster.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

Yes, Strathmartine is within the area we cover. Our work covers the whole of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.
I let a flat near Dundee station. Can you help?
Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Can new sealant go over the old?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
Can I paint over the new sealant?
It depends on the sealant. Silicone is not paintable, but some hybrid sealants are. Mention any painting plans before we start.
Can resealing stop a draught around my window?
Often, yes. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
Do you have insurance?
Yes. Mr Mastic is fully insured.
