What happens if it’s left?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will explain what it covers.

What window mastic looks like in Wasbister
Wasbister 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. Work on the islands has to be planned around ferry crossings and the weather, so the more notice, the better.
In and around Wasbister, as anywhere, good window mastic starts with a clean, dry, properly prepared joint. Historic houses such as Skaill House, about 3.6 miles north-west, show how far back building around Wasbister goes, and older homes nearby need a sealant that suits their walls.
Wasbister is about 11 miles west of Kirkwall, in the Orkney Islands. Whether you are in the middle of Wasbister or further out, we cover window mastic for every kind of property, from flats and houses to offices and hotels. Our the Orkney Islands coverage runs to 51 places, Wasbister among them.

What affects the cost of window mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- The product the joint needs
- Access and height
- Whether there’s mould to deal with
- Any working-time requirements on site
We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please email us at info@mrmastic.co.uk.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- Any access issues, like height or stairs
- How many joints, rooms or windows are involved
- A few pictures by email, if you can
- Where the job is, and your postcode
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Work for landlords, hotels and businesses
Hotels need rooms back in use, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Common questions in Wasbister
Is Wasbister in your area for window mastic?
Yes, Wasbister is within the area we cover. We work across all of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
Does living near the coast affect window mastic in Wasbister?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Can you do upstairs windows?
Yes, where it’s safe. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
What should I tell you?
Tell us what needs doing and where, plus photos if you have them. We will ask anything else we need to know.
What the job involves on each 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 keeps the clean look.
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.
When something else is needed
In fairness, there are a few things sealant will not fix:
- Damp coming through the wall itself rather than the frame joint
- Broken hinges, locks or handles
- Worn gaskets, brush seals or a door that has dropped
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before you book.
Joints and surfaces we work on
- Aluminium frames
- Timber windows & doors
- Patio & French doors
- Composite doors
- Window sills
- uPVC windows
How the visit works
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes a morning for a couple of windows and a door in most cases. Outside jobs in Wasbister need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Tell us about any water getting in
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height
