Window mastic in Toward
Frames and walls don’t move together. 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. We work on aluminium frames, window sills and uPVC windows, and common reasons people get in touch are leaking joints at the ends of sills and untidy mastic left by window fitters.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
There’s a 12-month guarantee on every job, large or small.

Should I try it myself first?
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 DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

What we’re called out for in Toward
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar didn’t grip properly, and it lets go sooner than it should.
People generally contact us after spotting something like this:
- White mastic on grey or black frames
- Untidy mastic left by window fitters
- Gaps between the frame and the inside reveal
- Gaps where the sill meets the wall
If you let a flat or house near Wemyss Bay station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Frames and glazing around Toward
Toward is within about 1 mile 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. Toward is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out.
In the older streets around Toward Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Toward questions
Do you cover smaller places like Toward?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Does living near the coast affect window mastic in Toward?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you.
Do you have insurance?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can you get sealant to suit coloured frames?
Yes, in most cases. Mention the frame colour when you ask for a quote and we will match it as closely as we can.
Will there be a smell?
Some sealants have a smell while they cure. Ventilation helps.
Landlords, agents and businesses in Toward
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
We also work for property managers and facilities teams in Toward and across Argyll and Bute. We can quote a run of properties together, and we’re fully insured.
The process
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes anything from an hour or two to a full day, depending on how many frames there are, including the tidy-up. Outdoor work around Toward 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 look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints

Advice
What the job involves on each surface
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the new bead is laid against the frame and the wall.
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We will tell you which suits your home.
What affects the cost of window mastic
The quote reflects the job in front of us. We take into account:
- The number of rooms or windows
- The old material and how stubborn it is
- The type of sealant required
- Any mould that needs treating
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
What we need to know
To make quoting easier, please include:
- The problem you’ve noticed
- Pictures of the joints, sent by email
- Where the property is
- Any access issues, like height or stairs
Need a quote? Please send an email to info@mrmastic.co.uk with a few details. We will explain what we’d do and give you a clear quote before we start.
What sealant work cannot fix
We won’t take on work that won’t last, so here’s what sealant cannot put right:
- A frame that has rotted at the joint
- Broken hinges, locks or handles
- Misting between the panes of a double-glazed unit (that needs a new unit)
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before you book.
