About our window mastic in Midland
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. Common call-outs are for cold air getting in at the frame edge and gaps where the sill meets the wall, on patio & French doors, aluminium frames and composite doors.
In and around a place like Midland, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
Our work is backed for twelve months, in Midland and everywhere else we cover.

Surface by surface
Patio & French doors
Water at the foot of a door frame is not always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
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.

Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
What window mastic looks like in Midland
Midland is within about 1 mile 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. Island jobs need planning around ferries and the weather, so give us as much notice as you can.
Homes close to Round Kirk include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Midland is about 9 miles south-west of Kirkwall, in the Orkney Islands. Our applicators cover window mastic for homes and businesses in Midland, as part of our work across the Orkney Islands. Midland is one of 51 towns and villages in the Orkney Islands where we work for window mastic.

When it isn’t the sealant
We’ll always be straight with you, so here’s what sealant can’t fix:
- Soft or decayed wood in the frame
- A door that needs adjusting, rehanging or new seals
- Broken hinges, locks or handles
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before booking.

What we do, step by step
The work is kept neat and contained to the joints we are treating, so you can carry on as normal. Expect the work to take a few hours for a few frames, or a day or more for a whole house, and we tell you how long to leave it before we go. Outside jobs in Midland need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Mention any tricky access
- Mention any leaks or damp you’ve noticed

Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Clean frames with a soft cloth and soapy water
- Keep timber frames painted
- Do not use solvent cleaners on the joint
- Wipe condensation off the frames
Most silicone sealants won’t take paint, so if you’re planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
What we’re called out for in Midland
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. If the sealant can’t stretch, it splits.
Look out for these signs:
- Black, perished sealant on frames
- Hard, cracked sealant around windows
- Cold air getting in at the frame edge
- Rain getting in at the frame or under the sill
In and around Midland, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Midland questions
Does living near the coast affect window mastic in Midland?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Is Midland in your area for window mastic?
Yes, Midland is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we are using and why.
Do you guarantee window mastic?
Yes. Our one-year guarantee covers every job.
Is it OK to seal over old sealant?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses.
Can new window sealant be painted?
That depends on the product. Silicone isn’t paintable, but some hybrid sealants are. Tell us if you’re decorating and we’ll choose accordingly.
Can landlords and businesses book you?
Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.
