Window & door mastic in Innellan, Argyll and Bute
Mastic around window and door frames, sills and patio doors in Innellan, with a 12-month guarantee on every job. Call for a quick quote.
- Cracked internal joints between frame and plaster
- Rain getting in at the frame or under the sill
- Leaking joints at the ends of sills
Leave it or put it right?
A quick bead over the top of old mastic looks like an easy fix, but new sealant cannot bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Around Innellan, water from a failed joint in an older stone home can soak into timber and plaster.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

How we handle window mastic in Innellan
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. If you have leaking joints at the ends of sills and gaps left after new windows were fitted, we can put it right, whatever the surface.
Outdoor sealant needs a dry surface, so window work around Innellan is planned around the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
We stand behind the work with a 12-month guarantee, so you’re covered after we’ve gone.

Frames and glazing around Innellan
Innellan 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. Innellan 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.

Innellan questions
Does living near the coast affect window mastic in Innellan?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Can you help a landlord with a rental near Wemyss Bay station?
Yes, landlords and agents are among the people we work for. You can email us at info@mrmastic.co.uk with the details for a clear quote.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply email us at info@mrmastic.co.uk.
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.
Can you do the inside joint as well?
Yes. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.
How do I get a quote for window mastic in Innellan?
Size, access and the old material all affect the cost. Ask us for a quote.
Can new window sealant be painted?
Silicone generally won’t take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Will resealing my frames help with draughts?
Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that’s a different fix, and we’ll say so.

What affects the cost of window mastic
The quote reflects the job in front of us. We look at:
- Whether the work is at height
- The old material and how stubborn it is
- Any mould that needs treating
- Working hours on commercial sites
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
What to tell us for a quote
When you contact us, it’s useful to know:
- The address or postcode of the job
- Whether it has been sealed before

What we cannot put right
A few problems are outside what sealant work can do:
- Damp coming through the wall itself rather than the frame joint
- Soft or decayed wood in the frame
- Faulty window hardware
If in doubt, email us at info@mrmastic.co.uk and we will say what we think.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Keep solvents and bleach off the sealant
- Air rooms to keep condensation down around windows
- Avoid blasting the frames with a pressure washer
- Clear any debris from frame drain holes
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
When to call us in Innellan
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, while a joint packed solid can’t stretch. Backing rod sets the right depth.
People generally contact us after spotting one of these:
- A bead that doesn’t match the frame
- Black, perished sealant on frames
- Whistling draughts around closed windows
- Mastic that has split away from the wall
Historic houses such as Castle Toward, about 2.4 miles south-west, show how far back building around Innellan goes, and older homes nearby need a sealant that suits their walls.

How it works
On the day, we start by going over the job with you. We protect the surfaces around the joints before any work begins. Most jobs take a morning for a couple of windows and a door. Outside jobs in Innellan need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- On commercial sites, let us know about site rules
- Clear the area around the work

Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
