How window mastic works in South Lanarkshire

A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. If the draught is through the window seals instead, we will tell you. Typical jobs include untidy mastic left by window fitters and old mastic that has gone black or come away, across window sills, aluminium frames and composite doors.

On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a morning for a couple of windows and a door, including the tidy-up.

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.
We clear up and check every joint is fully closed.

Windows and doors across South Lanarkshire

From East Kilbride, Hamilton and Cambuslang to its smaller places, South Lanarkshire has windows and doors of every age and material. The mastic around all of them ages, and it’s usually the first thing to let the weather in.

Homes in Scotland come with their own details: sash and case windows, harled walls and, in the towns and cities, tenement flats. We work across Scotland, including South Lanarkshire.

East Kilbride: For site and facilities teams at buildings such as Duncanrig Secondary School, the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to East Kilbride station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Landlord and commercial work in South Lanarkshire

Letting agents often deal with us directly. Tell us the address, the job and how access works and we will give you a quote.

Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.

Honest limits

Honest advice matters more to us than a booking, so here’s what sealant cannot fix:

Faulty window hardware
Penetrating damp from a failed cavity tray or render
Soft or decayed wood in the frame

Should I try it myself first?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

What affects the cost of window mastic

We quote each job individually. These are the things that affect it:

Mould in or behind the old joints
Working hours on commercial sites
The old material and how stubborn it is
Access and height

A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Helping us quote

You do not need to know the technical terms. It helps if you can tell us:

Access, such as stairs, a lift or height
The type of property
Pictures of the joints, sent by email
The problem you’ve noticed

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. Whenever you’re ready, email us at info@mrmastic.co.uk.

How the job changes by surface

Window sills

Stone and concrete sills have their own joints, including the one between the sill and the frame above. We seal those with a sealant suited to masonry.

Patio & French doors

Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that.

Questions from South Lanarkshire

Are you fully insured?

Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.

Can you work on commercial sites?

Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.

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 don’t need to watch us work.

Should I try DIY first?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

What do you put in the joint?

Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will tell you what we are using.
