Viewpark Window Mastic
Mastic around window and door frames, sills and patio doors for Viewpark, backed by a 12-month guarantee. Call for a quick quote.
- White mastic on grey or black frames
- Hard, cracked sealant around windows
- Untidy mastic left by window fitters
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
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 in Viewpark, done properly
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. We work on composite doors, window sills and patio & French doors, and common reasons people get in touch are cracked internal joints between frame and plaster and old mastic that has gone black or come away.
Mastic can only go onto a dry joint, so outside work in Viewpark depends on the weather. Tell us about access to all the windows and doors, upstairs included.
All our work comes with a 12-month guarantee, wherever you are in South Lanarkshire.

Why act early in Viewpark
Choosing the product is half the job. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear price before any work starts.

What affects the cost of window mastic
Call for a quick quote. What matters most is:
- Working hours on commercial sites
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
- Where the job is, and your postcode
We quote each job on its own. Just send an email to info@mrmastic.co.uk with the details.
Common questions in Viewpark
I let a flat near Uddingston station. Can you help?
Yes, rental work is part of what we do. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Is Viewpark in your area for window mastic?
Yes. Our work covers the whole of Scotland, and Viewpark is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Can you do the inside joint as well?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
What does window mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
Will resealing my frames help with draughts?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses, and we’re fully insured.
How long will my window job take?
That depends on the number of frames, how they’re reached and the state of the old mastic. You’ll know the timing when we quote.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
How it works
On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. The work generally takes most of a day for a typical house, less for a few frames. Around Viewpark, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Mention any tricky access
- Plan for the work area to be out of bounds to pets and children

Other services in Viewpark
For landlords and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Aftercare tips
To keep the joints looking good and working properly:
- Walk round the house once a year and look at the joints
- Keep drainage slots and sill grooves clear
- Keep timber frames painted
- Ventilate rooms so frames don’t stay wet inside
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just send an email to info@mrmastic.co.uk.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.
Viewpark homes and the weather
Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. The west of Scotland is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain.
If you live in an older home near Old Monkland Parish Church, the joint between an old wall and a newer frame is normally the first place rain gets in. If you look after a building such as Cardinal Newman High School, the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Uddingston station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
