Window mastic in St Mary's
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. If the draught is through the window seals instead, we will tell you. We work on aluminium frames, window sills and timber windows & doors, and people most often call us about untidy mastic left by window fitters and white mastic on grey or black frames.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Window mastic in St Mary's: local notes
St Mary's is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Island jobs need planning around ferries and the weather, so the more notice, the better.
In and around St Mary's, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
St Mary's is about 6 miles south of Kirkwall, in the Orkney Islands. For window mastic in and around St Mary's, please email us at info@mrmastic.co.uk for a quick quote. We cover the Orkney Islands from our Crawley base. Across the Orkney Islands, we cover 51 places, and St Mary's is one of them.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
What we do, step by step
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a morning for a couple of windows and a door. For a place like St Mary's, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- 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.
Preparing for the visit
- On commercial sites, let us know about site rules
- Let us know about earlier repairs to the joints
- Let us know if you’ve seen damp or leaks

Leave it or put it right?
Not every sealant suits a window. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

How the job changes by surface
Window sills
Where a sill meets brick or render, the ends often crack first. A tight seal at each end keeps rain out of the wall.
Composite doors
Front doors take the weather head on, and the top and bottom corners tend to fail first. We pay most attention there.
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together.
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.

Common problems we fix in St Mary's
Mastic ages in the weather. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
Signs it’s time to call us include:
- Cracked internal joints between frame and plaster
- White mastic on grey or black frames
- Mastic that’s falling out in pieces
- Rain getting in at the frame or under the sill
Whether the job is in St Mary's itself or nearby, the right material for each joint matters as much as a neat finish.
