Window mastic in Balerno, done properly
Homes in Balerno have every kind of window: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on window sills, timber windows & doors and uPVC windows, and the jobs we see most are draughts coming in around windows and doors and gaps between the frame and the inside reveal.
Outdoor sealant needs a dry surface, so window work around Balerno is planned around the weather. Let us know about access to every frame, including any upstairs.
Every job comes with a 12-month guarantee.

Surface by surface
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. Each is cleaned out and resealed.
Signs you need window mastic in Balerno
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, so it comes away long before its time.
It’s worth asking for a quote if you see:
- Draughty joints inside around the window
- Water coming in at the bottom corners of a door
- A bead that does not match the frame
- Old mastic that has gone black or come away
For site and facilities teams at buildings such as Balerno Community High School, the mastic around its windows and doors needs looking after like any other building’s.

Why deal with it now?
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. Around Balerno, water from a failed joint in an older stone home can soak into timber and plaster.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Ask us for a quote and we will explain what it covers.
Why book with us
- Arbo and Everbuild products
- We never seal over old sealant
- A sealant colour to suit the surroundings
- White, clear, grey or another colour, product permitting

Windows and doors in Balerno
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
In the older streets around St Mungo's Episcopal Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Curriehill station, renewing tired window mastic between tenants heads off draught and damp complaints.

The work usually takes a morning for a couple of windows and a door. Outdoor work around Balerno depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- For business premises, tell us about site rules or sign-in

Advice
Questions from Balerno
Do you cover Balerno for window mastic?
Yes, Balerno is within the area we cover. We work across all of Scotland. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we’ll send you a clear quote.
Is Balerno within the area you cover?
Yes, we do. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords and businesses?
Yes, regularly. Several properties can go on one quote, and between tenancies is a good time for the work.
Do you have insurance?
Yes. We are fully insured, and we have been doing sealant work for more than 20 years.
Can you do the inside joint as well?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
Can tenants book the work?
Yes. Check with your landlord; we can send the quote to them too.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- A door that needs adjusting, rehanging or new seals
- A sash or casement that won’t close properly
- Rotten timber, which needs a joiner first
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before you book.
Joints and surfaces we work on
- Window sills
- Aluminium frames
- uPVC windows
- Timber windows & doors
- Composite doors
- Patio & French doors
Keeping the joints in good condition
So the new joints stay in good condition:
- Don’t aim a pressure washer at the joints
- Keep paint and stain on wooden frames in good order
- Wash the frames with mild soapy water
- Wipe condensation off the frames
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
