DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, 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.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Window mastic for homes and businesses in Fowlis
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you are dealing with mastic that has split away from the wall and rushed sealant from a window installation, we can help.
In and around a place like Fowlis, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

How to look after the new joints
Aftercare is simple:
- Don’t paint over the silicone
- Use gentle cleaners on frames and sealant
- Clear any debris from frame drain holes
- Don’t aim a pressure washer at the joints
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.

What window mastic looks like in Fowlis
Fowlis is within about 3 miles of 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Letting a property close to Invergowrie station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

When it is not the sealant
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- A sash or casement that won’t close properly
- Draughts through the window seals rather than the frame
- Rotten timber, which needs a joiner first
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think before you book.

Fowlis: your questions answered
Is Fowlis within the area you cover?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Does living near the coast affect window mastic in Fowlis?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you when we finish.
Where are you based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Can you do upstairs windows?
Yes, in most cases. Access is planned before we start.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Do you need window mastic in Fowlis?
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar never bonded as it should, and it lets go sooner than it should.
The problems people generally mention when they call include:
- Cold air getting in at the frame edge
- Cracked internal joints between frame and plaster
- Gaps where the sill meets the wall
- White mastic on grey or black frames
Homes close to Fowlis Easter Church And Churchyard include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How the visit works
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes most of a day for a typical house, less for a few frames. Outdoor work around Fowlis depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- 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
- Clear items away from the joints we are working on
- Tell us if parking is tricky
- Keep children and pets away from the work area
