Window mastic for homes and businesses in Newlands
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 for window mastic in Newlands. We work on window sills, uPVC windows and patio & French doors, and the jobs we see most are cracked sealant at the sill ends and whistling draughts around closed windows.
Sash and case windows are a feature of older tenements in all four Scottish cities, and plenty still have them. Whether you are in a tenement flat or a house in Newlands, the joint between frame and wall is what keeps the weather out.
All of our work is guaranteed for twelve months, in Newlands and everywhere else we cover.

What we’re called out for in Newlands
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
Keep an eye out for these signs:
- Hard, cracked sealant around windows
- Untidy mastic left by window fitters
- Leaking joints at the ends of sills
- Sealant in the wrong colour for the frame
For site and facilities teams at buildings such as Hillpark Secondary School, larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- Which sealant they’ll use, and why
- What guarantee comes with the work
- Who turns up on the day
- Whether all the old sealant comes out first
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Avoid blasting the frames with a pressure washer
- Keep paint off silicone joints
- Clear any debris from frame drain holes
- Wipe condensation off the frames
Silicone cannot usually be painted, so mention any painting plans before any work starts. We can use a paintable sealant where that matters.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What happens on the day
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It generally takes a morning for a couple of windows and a door. In a city area like Newlands, parking may be by permit or pay-and-display, so tell us what’s nearby. If you’re in a flat, let us know how we get in at the street door.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Clear the area around the work
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises

Advice
What sealant work can’t fix
We’d rather tell you now than do work that won’t last, so these are the limits:
- A failed sealed unit that has misted up
- Draughts through the window seals rather than the frame
- 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 will tell you honestly.

Newlands homes and the weather
Historic houses like Pollok House (about 1.6 miles north-west) are a reminder that the area around Newlands has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is 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.
Homes close to Merrylea Parish Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you let a flat or house near Langside station, renewing tired window mastic between tenants heads off draught and damp complaints.

What affects the cost of window mastic
The price is agreed before any work begins. It takes into account:
- How many areas need sealing
- Whether old sealant or filler has to be cut out
- Any mould that needs treating
- Which sealant suits the joint
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
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
- Whether it has been sealed before
- What the problem is, such as mould, gaps, leaks or cracking

FAQs for Newlands
Can you do window mastic in Newlands?
Yes, Newlands is within the area we cover. We work across all of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job.
Who arranges sealant work on the shared parts of a tenement in Newlands?
Shared parts of a tenement, such as the roof and outside walls, are usually repaired with the agreement of the owners, often through a property factor. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Your title deeds will say who owns the windows.
Can I paint over the new sealant?
It depends on the sealant. Some hybrid sealants can be painted; silicone can’t. Tell us if you are decorating and we’ll choose accordingly.
Will new mastic stop draughts?
In many cases. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.
How long does it take to reseal the windows on a house?
It depends on access, the old mastic and the size of the frames. We’ll tell you how long your job needs when we quote.
Can landlords and businesses book you?
Yes. We work in homes, commercial premises and hotels.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
