Window mastic in Inverness, done properly
There are two joints on most windows. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. We work on patio & French doors, uPVC windows and composite doors, and common reasons people get in touch are black, perished sealant on frames and draughts coming in around windows and doors.
Harled walls are common in Scottish towns like Inverness, and the joint between a frame and rough harling needs a sealant that can grip and flex. A bead that sits on top of the harling rather than in the joint soon lets water in.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Window mastic in Inverness: local notes
Inverness 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.
For landlords with property near Inverness station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
Inverness (Gaelic: Inbhir Nis) is in Highland. Homes, rented property, offices and hotels in Inverness is covered for window mastic, old or new, large or small. The work is guaranteed for a year. Inverness is one of 253 towns and villages in Highland we cover.
Here we cover the IV2, IV3 and IV1 postcode area for window mastic. That includes homes and businesses on High Street, Market Brae and Falcon Square. Being close to the A9 and A82, Inverness is easy for our applicators to reach. Nearby, we also carry out window mastic in Ballifeary (1 mile west), Crown (1 mile north-east), Hilton (1 mile south-east), Millburn (1 mile north-east) and Lochardil (1 mile south). Further out, we also cover Nairn (15 miles north-east), Cradlehall (3 miles east), Dingwall (12 miles north-west), Muir of Ord (9 miles west), Fortrose (8 miles north-east) and Conon Bridge (10 miles north-west). Being one of Highland’s larger places, Inverness has homes, rented property and businesses of every kind. If you are somewhere remote, the job takes a little more planning.

What we can’t put right
In fairness, some problems need a different trade:
- Rotten timber, which needs a joiner first
- Draughts through the window seals rather than the frame
- Faulty window hardware

For landlords and businesses
If you manage several properties in or around Inverness, several properties can be quoted together. Send us the addresses and the work at each.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
What the job involves on each surface
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.
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.
Your questions about window mastic in Inverness
Is Inverness in your area for window mastic?
Yes. Our work covers the whole of Scotland, and Inverness is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Do you work for landlords with property near Inverness station?
Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Do you have insurance?
Yes. We’re fully insured for every job we do.
Can you reach windows above the ground floor?
Yes, if safe access is possible. For high or awkward windows, we will tell you what access is needed.
Can you seal the gap between the frame and the plaster indoors?
Yes. Inside, the joint between frame and plaster is sealed neatly.
Can new window sealant be painted?
That depends on the product. Some hybrid sealants can be painted; silicone can’t. Tell us if you’re decorating and we will choose accordingly.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Wash the frames with mild soapy water
- Clear any debris from frame drain holes
- Look round the frames every year or so
- Repaint timber before it’s bare
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
Leaks generally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes most of a day for a typical house, less for a few frames. For a job in Inverness, tell us where the work is, how to get in and where to park. Outside work depends on the weather, as sealant needs a dry surface.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work
- Mention any leaks or damp you’ve noticed
Getting a quote
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job.
Related advice
Why deal with it now?
If you are painting or rendering, reseal at the same time. Fresh joints finish the job neatly. Scottish weather finds any gap, and in a town like Inverness, failed outside joints soon let damp into walls. Inside, a failed seal around a bath or shower lets water into floors and ceilings.
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.
Why book with us
- One-year guarantee on every job
- White, clear, grey or another colour, product permitting
- You choose the colour before work begins
- An ARBOMaster approved applicator

Do you need window mastic in Inverness?
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. A sealant that cannot keep up eventually tears.
The most common problems we see are:
- Sealant in the wrong colour for the frame
- Cold air getting in at the frame edge
- Mastic that’s falling out in pieces
- Damp patches on the reveal after heavy rain
If you look after a building such as Inverness High School, the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before you book
- Who does the work, and how experienced they are
- Is the old sealant removed completely?
- Whether the sealant suits the joint
- Are they insured?
