How we handle window mastic in Acharacle
Around Acharacle we seal all kinds of frames: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on uPVC windows, timber windows & doors and patio & French doors, and common reasons people get in touch are gaps left after new windows were fitted and cracked or shrunken mastic around the frame.
Outdoor sealant needs a dry surface, so window work around Acharacle is planned around the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
Your job is guaranteed for a year, as with all our work.

Frames and glazing around Acharacle
Acharacle is close to 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. Acharacle is in the west of Scotland, which is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain.
For jobs in and around Acharacle, choosing the right material for each joint is as important as a tidy finish.

What else we do in Acharacle
Different surfaces, different methods
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. Each is cleaned out and resealed.
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
Looking after it afterwards
To keep the joints looking good and working properly:
- Walk round the house once a year and look at the joints
- Don’t use solvent cleaners on the joint
- Make sure the drainage slots aren’t blocked
- Keep timber frames painted
Silicone can’t usually be painted, so if you’re planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
How the visit works
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a few frames, or a day or more for a whole house. Outdoor work around Acharacle 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 how each frame can be reached safely.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks

Common questions in Acharacle
Will you come out to Acharacle?
Yes. Acharacle is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you cover Acharacle for window mastic?
Yes. We work across all of Scotland, and Acharacle is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Can resealing stop a draught around my window?
In many cases. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Can you get sealant to suit coloured frames?
Generally, yes. Mention the frame colour when you ask for a quote and we’ll match it as closely as we can.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Is there any odour?
Possibly a little. It fades as the sealant cures, and ventilation helps.
How do I get a quote for window mastic in Acharacle?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before any work starts.
What affects the cost of window mastic
We don’t publish a price list, because jobs vary so much. The quote depends on:
- The number and length of the joints
- The product the joint needs
- Any working-time requirements on site
- Mould in or behind the old joints
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- A few photos by email, if you can
- Roughly how big the job is
- Where the property is
- The type of property
For a quote, drop us a line at info@mrmastic.co.uk and tell us where the job is and what the problem looks like. We will send you a clear quote before any work starts.
Common problems we fix in Acharacle
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
Look out for these signs:
- Untidy mastic left by window fitters
- Cracked internal joints between frame and plaster
- Gaps where the sill meets the wall
- Water coming in at the bottom corners of a door
In and around Acharacle, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
Questions to ask before you book
- What insurance they hold
- Is VAT in the price?
- How the colour is chosen
- Is the old sealant removed completely?
When something else is needed
We won’t take on work that won’t last, so here’s what sealant can’t put right:
- A door that needs adjusting, rehanging or new seals
- A frame that has rotted at the joint
- A failed sealed unit that has misted up
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think.
