When something else is needed
A few problems are outside what sealant work can do:
- A sash or casement that won’t close properly
- Condensation trapped between the panes
- Soft or decayed wood in the frame
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before you book.
Where we work in Harray
- Window sills
- Composite doors
- Patio & French doors
- Timber windows & doors
- uPVC windows
- Aluminium frames
How the job changes by surface
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so we pay close attention there.
Do you need window mastic in Harray?
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
Signs it’s time to call us include:
- Gaps between the frame and the inside reveal
- Untidy mastic left by window fitters
- Old mastic that has gone black or come away
- Damp patches on the reveal after heavy rain
In and around Harray, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
Before booking anyone
- Who does the work, and how experienced they are
- Whether they seal over old material or remove it
- How the colour is chosen
- What happens if they find a problem under the old sealant
How it works
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself usually takes anything from an hour or two to a full day, depending on how many frames there are, depending on the size of the job. Somewhere like Harray may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
How to prepare
- Mention any tricky access
- Tell us about any water getting in
- Keep pets and children clear of the area while we work

Related advice
What window mastic looks like in Harray
Harray is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is 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 failed outside joints work against that.
For an older house near a landmark such as Grimeston Congregational Chapel, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Harray is about 9 miles north-west of Kirkwall, in the Orkney Islands. Whether you’re in the middle of Harray or further out, window mastic is available for homes and businesses alike. Our area takes in 51 places across the Orkney Islands.

If you are just outside Harray, we cover Bimbister (1 mile south), Russland (1 mile west), Grimeston (2 miles south), Hourston (2 miles north-west) and Wasbister (3 miles south-west).

DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Landlord and commercial work in Harray
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.

Harray questions
Is Harray within the area you cover?
Yes. Harray is within the area we cover, which takes in towns, villages and rural addresses. We work across all 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.
Does living near the coast affect window mastic in Harray?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Can you get sealant to suit coloured frames?
Yes. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Can I add another job to the visit?
Of course. Doing several areas at once is normally more efficient.

What happens if it’s left?
Draughts and leaks do not always mean new windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. If we find failed glass units or worn seals, we will tell you. Around Harray, water from a failed joint in an older stone home can soak into timber and plaster.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.
