Window mastic in Shotts, done properly
From a single sill to a whole house of windows, the work is priced before anything is done. To get one, drop us a line at info@mrmastic.co.uk with the number of frames and any access details. We work on patio & French doors, composite doors and uPVC windows, and the jobs we see most are cracked sealant at the sill ends and gaps between the frame and the inside reveal.
Outdoor sealant needs a dry surface, so window work around Shotts is planned around the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
All of our work is guaranteed for twelve months, in Shotts and everywhere else we cover.

Looking after it afterwards
So the new joints stay in good condition:
- Wipe condensation off the frames
- Do not aim a pressure washer at the joints
- Do not use solvent cleaners on the joint
- Clean frames with a soft cloth and soapy water
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
How the visit works
We keep the work tidy and contained to the joints we are treating. The job generally takes a morning for a couple of windows and a door, and we tell you how long to leave it before we go. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules
Ask for a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.

Also in Shotts
Different surfaces, different methods
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the sealant goes in between frame and wall and tooled smooth.
Composite doors
A composite door usually sits in a plastic outer frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
FAQs for Shotts
I let a flat near Shotts station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Is Shotts in your area for window mastic?
Yes, Shotts is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Can you seal over the old sealant?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Can you reach windows above the ground floor?
Yes, in most cases. Access is planned before any work starts, so mention the height and anything in the way.
When is the sealant fully cured?
It depends on the product and the conditions. We tell you how long to leave it before we go.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages.

What we can’t put right
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- A frame that has rotted at the joint
- Worn gaskets, brush seals or a door that has dropped
- Penetrating damp from a failed cavity tray or render
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly before you book.

Frames and glazing around Shotts
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
In and around Shotts, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Signs you need window mastic in Shotts
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, while a joint packed solid can’t stretch. Backing rod sets the right depth.
Look out for these signs:
- Gaps where the sill meets the wall
- Cracked or shrunken mastic around the frame
- White mastic on grey or black frames
- Gaps between the frame and the inside reveal
For landlords with property near Shotts station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
