Window & door mastic in Kirkwall, Orkney Islands
Mastic around window and door frames, sills and patio doors for homes and businesses in Kirkwall and across the Orkney Islands. Fully insured, ARBOMaster approved and guaranteed for a year.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Wipe condensation off the frames
- Look round the frames every year or so
- Avoid harsh chemicals near the mastic
- Clear any debris from frame drain holes
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
Window mastic for homes and businesses in Kirkwall
Frames and walls don’t move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on composite doors, patio & French doors and uPVC windows, and the jobs we see most are a bead that doesn’t match the frame and damp patches on the reveal after heavy rain.
In a town like Kirkwall, stone-built older streets generally sit alongside harled houses and newer estates, and windows range from older sash and case to modern uPVC. The sealant has to suit both the frame and the wall it sits in.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

What sealant work can’t fix
A few problems are outside what sealant work can do:
- Worn gaskets, brush seals or a door that has dropped
- A frame that has rotted at the joint
- Damp coming through the wall itself rather than the frame joint
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.

Why it’s worth doing now in Kirkwall
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. For landlords in Kirkwall, damp and leaks can fall under the Repairing Standard. Replacing failed sealant early is simpler than dealing with a complaint.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and give you a clear quote before we start.

How it works
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a morning for a couple of windows and a door. A visit in Kirkwall needs three things planned: access, parking and where the work is. Outside work depends on the weather, as sealant needs a dry surface.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Let us know about stairs, lifts or work at height
- Keep children and pets away from the work area
- Clear items away from the joints we are working on

What affects the cost of window mastic
Jobs vary more than people expect. The main factors:
- Whether the work is at height
- The number and length of the joints
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- How we’d reach the joints
- If someone has resealed it before
- The address or postcode of the job
- A few pictures by email, if you can
Every job is quoted individually, so start by telling us what you need. Simply email us at info@mrmastic.co.uk and describe the job, and photos are welcome.
Surface by surface
Composite doors
An exposed front door gets wind-driven rain. Those corners get the most care.
Window sills
Where a sill meets brick or render, the ends often crack first. We reseal them so rain can’t run into the wall.

Frames and glazing around Kirkwall
Kirkwall is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Work on the islands has to be planned around ferry crossings and the weather, so give us as much notice as you can.
For site and facilities teams at buildings such as Kirkwall Grammar School, its window and door frames need their mastic kept sound, just like a home’s.
Kirkwall is in the Orkney Islands. Kirkwall gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a one-year guarantee. We cover 51 towns and villages across the Orkney Islands, large and small.

Questions from Kirkwall
What guarantee comes with window mastic in Kirkwall?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Does living near the coast affect window mastic in Kirkwall?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Is there any odour?
Some sealants have a smell while they cure. Ventilation helps.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint.
Do you seal inside as well as outside?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few photos.
What does window mastic cost?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before any work starts.
When to call us in Kirkwall
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. A sealant that can’t keep up eventually tears.
People usually contact us when they notice one of these:
- Damp patches on the reveal after heavy rain
- Draughty joints inside around the window
- Black, perished sealant on frames
- Cold air getting in at the frame edge
In the older streets around Paterson Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
