Window mastic in Germiston, done properly
The new joint does not have to be white. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. Common call-outs are for cracked internal joints between frame and plaster and water coming in at the bottom corners of a door, on uPVC windows, composite doors and window sills.
Mastic can only go onto a dry joint, so outside work in Germiston depends on the weather. Let us know about access to every frame, including any upstairs.
Every job is covered by our one-year guarantee.

Window mastic in Germiston: local notes
Germiston is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. 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.
Whether the job is in Germiston itself or nearby, the right material for each joint matters as much as a neat finish. Around Germiston, as everywhere, window mastic is only as good as the preparation behind it.
Germiston is about 7 miles west of Kirkwall, in the Orkney Islands. Homes, rented property, offices and hotels in Germiston is covered for window mastic, old or new, large or small. The work is guaranteed for a year. Across the Orkney Islands, we cover 51 places, and Germiston is one of them.

The process
You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes most of a day for a typical house, less for a few frames for a typical job. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Let us know about earlier repairs to the joints
- Keep children and pets away from the work area
- Where the joints are inside, avoid wetting them before we arrive

Your questions about window mastic in Germiston
Does living near the coast affect window mastic in Germiston?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Will you come out to Germiston?
Yes. Germiston is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland, including the islands, where work is planned around ferry crossings. Just mention lanes, gates or anything else about the route when you book.
Do you guarantee window mastic?
Yes, with our one-year guarantee. Keeping drainage clear and checking the joints yearly helps them last.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Germiston.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Are you fully insured?
Yes. Full insurance covers our work.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. Then email us at info@mrmastic.co.uk.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep drainage slots and sill grooves clear
- Repaint timber before it’s bare
- Air rooms to keep condensation down around windows
- Avoid blasting the frames with a pressure washer
Most silicone sealants won’t take paint, so if you’re planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
How the job changes by surface
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match suits the frame.
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain can’t run into the wall.
When it isn’t the sealant
We will not take on work that won’t last, so these are the limits:
- Rotten timber, which needs a joiner first
- Worn gaskets, brush seals or a door that has dropped
- Misting between the panes of a double-glazed unit (that needs a new unit)
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think before booking.
Joints and surfaces we work on

- Any working-time requirements on site
- Whether the work is at height
- Mould in or behind the old joints
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Whether it has been sealed before
- Whether it’s a home or a business
- Any access issues, like height or stairs
- The address or postcode of the job
We quote each job on its own, so start by telling us what you need. Simply email us at info@mrmastic.co.uk and describe the job and send pictures if you have them.
