Window mastic in Ardfern, done properly
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. If you’re dealing with rushed sealant from a window installation and whistling draughts around closed windows, we can put it right, on patio & French doors, composite doors and aluminium frames alike.
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.
Every job is covered by a one-year guarantee, wherever you are in Argyll and Bute.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Repaint timber before it’s bare
- Don’t use solvent cleaners on the joint
- Avoid blasting the frames with a pressure washer
- Wash the frames with mild soapy water
Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.
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. Catching it early keeps the fix to a reseal.
How the job changes by surface
Aluminium frames
Coated aluminium needs a compatible sealant and we avoid acetoxy silicones, which can react with some metals. We use a neutral-cure product.
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
Ardfern homes and the weather
Ardfern is close to 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
In and around Ardfern, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

What we do, step by step
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a morning for a couple of windows and a door. For a place like Ardfern, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Before we arrive
- On commercial sites, let us know about site rules
- Clear the area around the work

Common questions in Ardfern
Does the coastal weather in Ardfern affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Do you cover smaller places like Ardfern?
Yes. Ardfern is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can landlords and businesses book you?
Yes, we do. We work in homes, commercial premises and hotels, and we are fully insured.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Can I paint over the new sealant?
It depends on the sealant. Silicone is not paintable, but some hybrid sealants are. Mention any painting plans before we start.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Signs you need window mastic in Ardfern
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
It’s worth asking for a quote if you see:
- Draughts coming in around windows and doors
- Gaps between the frame and the inside reveal
- Rushed sealant from a window installation
- Black, perished sealant on frames
For an older house near a landmark such as Craignish Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What affects the cost of window mastic
You will get a clear quote before we start. It’s based on:
- The type of sealant required
- Mould in or behind the old joints
- How many areas need sealing
- The size of the job
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Helping us quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- If someone has resealed it before
- What’s wrong with the joints now
- A few photos by email, if you can
- Where the property is
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you’re ready, drop us a line at info@mrmastic.co.uk.
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

Leave it or put it right?
Choosing the product is half the job. Interior caulk and bathroom silicone aren’t made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. In a place like Ardfern, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, send an email to info@mrmastic.co.uk for an honest opinion and a quote.
What you get with us
- An ARBOMaster approved applicator
- Colour agreed with you before work begins
- A choice of colours where the product allows
- Anti-fungal silicone where joints get wet
