The Murray Window Mastic
Problem with your window and door frames in The Murray? We remove the old material, prepare the joints and seal them properly.
- Rain getting in at the frame or under the sill
- Cracked sealant at the sill ends
- A bead that doesn’t match the frame
Window mastic in The Murray, done properly
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through. If the draught is through the window seals instead, we will tell you. Common call-outs are for hard, cracked sealant around windows and damp patches on the reveal after heavy rain, across timber windows & doors, uPVC windows and patio & French doors.
Mastic can only go onto a dry joint, so outside work in The Murray depends on the weather. Let us know about access to every frame, including any upstairs.
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.

What we’re called out for in The Murray
Every frame moves through the day. 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.
Most people get in touch after spotting something like this:
- Cracked or shrunken mastic around the frame
- Mastic that is falling out in pieces
- Leaking joints at the ends of sills
- White mastic on grey or black frames
For site and facilities teams at buildings such as St Andrew's and St Bride's High School, larger buildings have plenty of frames, and the mastic around each one ages.

Frames and glazing around The Murray
The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out. 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 East Kilbride station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

Aftercare tips
After the cure time, these simple habits help:
- Keep solvents and bleach off the sealant
- Use gentle cleaners on frames and sealant
- Avoid blasting the frames with a pressure washer
- Keep drainage slots and sill grooves clear
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just drop us a line at info@mrmastic.co.uk.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
Why deal with it now?
Working on frames from a ladder with a sealant gun isn’t easy, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. Around The Murray, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.
Why The Murray customers choose us
- Over 20 years’ experience
- Full insurance on every job
- Any old sealant cut out fully, not covered over
- Homes, businesses and hotels
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
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 doesn’t work out, we can still put it right.
The process
When we arrive, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for a handful of frames, longer for a whole house. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Preparing for the visit
- Mention if the joints have been sealed before
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children

Advice
When it isn’t the sealant
We’d rather tell you now than do work that won’t last, so these are the limits:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Soft or decayed wood in the frame
- Damp coming through the wall itself rather than the frame joint
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.
Surfaces we seal
- Window sills
- Aluminium frames
- Composite doors
- Timber windows & doors
- uPVC windows

What affects the quote in The Murray
Your quote is based on your job. We look at:
- Whether there’s mould to deal with
- The old material and how stubborn it is
- Which sealant suits the joint
- Any working-time requirements on site
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- How we’d reach the joints
- What’s wrong with the joints now
- Photos by email, if that is easy
- Whether it’s a home or a business
We do not publish a price list, because every job is different. Instead, we give you a clear quote for your job. To arrange one, email us at info@mrmastic.co.uk.
