Window mastic for homes and businesses in Greenock
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty. If the draught is through the window seals instead, we’ll tell you. We work on composite doors, timber windows & doors and uPVC windows, and common reasons people get in touch are whistling draughts around closed windows and leaking joints at the ends of sills.
Scottish weather is hard on window mastic, and a town like Greenock gets its share of wind and rain. Frames on the side that takes the weather usually fail first.
There’s a 12-month guarantee on every job, whatever its size.

Your questions about window mastic in Greenock
I let a flat near Drumfrochar station. Can you help?
Yes, we work for landlords and letting agents. Just send an email to info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear quote.
Can you do window mastic in Greenock?
Yes. Our work covers the whole of Scotland, and Greenock is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we’ll send you a clear quote.
Where do you work from?
We are based in Crawley, and we work across South East England, London and Scotland.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access.
Can resealing stop a draught around my window?
Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that’s a different fix, and we will say so.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Can you reach windows above the ground floor?
Yes, if safe access is possible. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Greenock homes and the weather
Greenock is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Ardgowan House, about 4.1 miles south-west, is one of the historic houses in the wider area around Greenock. If you look after a building such as Wellington Academy, larger buildings have plenty of frames, and the mastic around each one ages.

Different surfaces, different methods
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. Those corners get the most care.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Wipe condensation off the frames
- Do not aim a pressure washer at the joints
- Repaint timber before it’s bare
- Keep drainage slots and sill grooves clear
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
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.
Why deal with it now?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. In Greenock, wind and rain soon get through failed outside joints. Indoors, failed sealant lets water into floors and ceilings.

What happens on the day
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for a handful of frames, longer for a whole house. In a Scottish town like Greenock, parking is generally straightforward, though older centres can be tighter. If you’re in a flat with a shared stair or a door entry system, let us know when you book.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- 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
- Move anything stored near the joints
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about parking restrictions
How to get a quote
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand, and we will take it from there.

When to call us in Greenock
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
Look out for any of the following:
- Black, perished sealant on frames
- Gaps between the frame and the inside reveal
- Hard, cracked sealant around windows
- Cracked sealant at the sill ends
Letting a property close to Drumfrochar station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
