About our window mastic in Greenhills
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty. If the draught is through the window seals instead, we’ll tell you. Typical jobs include water coming in at the bottom corners of a door and mastic that has split away from the wall, on aluminium frames, timber windows & doors and composite doors.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain.
Each job carries a 12-month guarantee, whatever its size.

What happens on the day
We keep the work tidy and contained to the joints we are treating, so you can get on with your day. The job usually takes most of a day for a typical house, less for a few frames, and we explain the cure time before we leave. Somewhere like Greenhills may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We check each frame and agree which ones need doing.
- 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.

Quotes for window mastic in Greenhills
There’s no set price list, because no two jobs are the same. What we look at:
- The amount of work
- Which sealant suits the joint
- Any working-time requirements on site
- Whether there’s mould to deal with
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Helping us quote
You don’t need to know the technical terms. It helps if you can tell us:
- If someone has resealed it before
- If it’s domestic, commercial or a hotel
- The address or postcode of the job
- What’s wrong with the joints now
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear price for your job. To get started, drop us a line at info@mrmastic.co.uk.
What happens if it’s left?
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. In a place like Greenhills, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we’ll go through it with you.

Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Windows and doors in Greenhills
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Greenhills is in the west of Scotland, which is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain.
Rented homes near East Kilbride station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Greenhills questions
I let a flat near East Kilbride station. Can you help?
Yes. We work for landlords and letting agents as well as householders. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
Do you cover smaller places like Greenhills?
Yes. Greenhills is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Can I add another job to the visit?
Of course. Doing several areas at once is usually more efficient.
Is the new sealant paintable?
Silicone generally won’t take paint. Let us know beforehand, and we’ll use a paintable product where it suits.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses, and we’re fully insured.
Does the work come with a guarantee?
Yes, for 12 months. A yearly look at the joints helps them last.
For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Signs you need window mastic in Greenhills
Mastic ages in the weather. Sunlight dries the surface out, until it loses its stretch and starts to crack.
It’s worth asking for a quote if you see:
- Draughty joints inside around the window
- Damp patches on the reveal after heavy rain
- Hard, cracked sealant around windows
- Black, perished sealant on frames
Managing a site like Duncanrig Secondary School? Then its window and door frames need their mastic kept sound, just like a home’s.
