How the job changes by surface
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
Aluminium frames
Aluminium needs a sealant that bonds to coated metal, and acetoxy silicones are not used, as they can attack some metals. We use a neutral-cure product.
How we handle window mastic in Reay
Homes in Reay have every kind of window: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on timber windows & doors, aluminium frames and uPVC windows, and the jobs we see most are leaking joints at the ends of sills and sealant in the wrong colour for the frame.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
There’s a 12-month guarantee on every job, whatever its size.

Leave it or put it right?
If you are painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Around Reay, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Common problems we fix in Reay
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, so it comes away long before its time.
The most common problems we see are:
- Cold air getting in at the frame edge
- Hard, cracked sealant around windows
- Rushed sealant from a window installation
- Old mastic that has gone black or come away
Around Reay, as everywhere, window mastic is only as good as the preparation behind it.

- How the colour is chosen
- Which sealant they’ll use, and why

When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:

- Broken hinges, locks or handles
- Draughts through the window seals rather than the frame

Reay homes and the weather
Reay 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Homes close to Reay Parish Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of frames, longer for a whole house and we leave things clean and tidy. Outdoor work around Reay depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.

Reay questions
Does living near the coast affect window mastic in Reay?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Do you cover Reay for window mastic?
Yes. We work across all of Scotland, and Reay is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Will there be a smell?
There can be a smell while the sealant cures. Ventilation helps.
How do I get a quote for window mastic in Reay?
Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Is it OK to seal over old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
