DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Window mastic for homes and businesses in Little Dunkeld
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty. Where the air is getting in through the window itself, we will say so. If you have rushed sealant from a window installation and sealant in the wrong colour for the frame, we can put it right, on timber windows & doors, uPVC windows and composite doors alike.
Mastic can only go onto a dry joint, so outside work in Little Dunkeld depends on the weather. Tell us about access to all the windows and doors, upstairs included.
Big or small, it’s backed by our one-year guarantee in Little Dunkeld and across Perth and Kinross.

How the job changes by surface
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so they get particular care.
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
What happens if it’s left?
Failed mastic is not 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. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep paint and stain on wooden frames in good order
- Don’t use solvent cleaners on the joint
- Wipe condensation off the frames
- Avoid blasting the frames with a pressure washer
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Leaks generally show up in wet, windy weather, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.

What window mastic looks like in Little Dunkeld
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Rented homes near Dunkeld & Birnam station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. For an older house near a landmark such as Little Dunkeld Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What we do, step by step
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a few frames, or a day or more for a whole house. Outside jobs in Little Dunkeld need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Getting ready for the visit
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
