About our window mastic in Kirkmuirhill
Some gaps around frames are far deeper than they look. 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. We work on uPVC windows, patio & French doors and composite doors, and common reasons people get in touch are draughty joints inside around the window and leaking joints at the ends of sills.
In and around a place like Kirkmuirhill, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain.
A 12-month guarantee comes as standard.

What else we do in Kirkmuirhill
What we are called out for in Kirkmuirhill
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
People usually contact us when they notice one of these:
- Cracked or shrunken mastic around the frame
- Cracked internal joints between frame and plaster
- Draughts coming in around windows and doors
- Untidy mastic left by window fitters
If you look after a building such as Lesmahagow High School, the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before booking
- The length of the guarantee
- Whether VAT is included

For landlords and businesses
Landlords and letting agents in Kirkmuirhill can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
How the job changes by surface
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the sealant goes in between frame and wall and tooled smooth.
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. Those corners get the most care.
Windows and doors in Kirkmuirhill
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For an older house near a landmark such as Kirkmuirhill 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
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a few frames, or a day or more for a whole house. Outside jobs in Kirkmuirhill need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- 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.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property

What affects the quote in Kirkmuirhill
We do not publish a price list. The quote depends on:
- The amount of work
- Access and height
- How many rooms, windows or areas are involved
- Whether there’s mould to deal with
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Paint up to the joint, not over it
- Make sure the drainage slots aren’t blocked
- Keep paint and stain on wooden frames in good order
- Check the mastic once a year
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
