For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
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.
Window mastic in Ardeer, done properly
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. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. Common call-outs are for rain getting in at the frame or under the sill and cracked or shrunken mastic around the frame, across composite doors, uPVC windows and timber windows & doors.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

How the job changes by surface
Patio & French doors
Water at the foot of a door frame is not always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so the joint must stay flexible. The paint or stain needs to be sound where the sealant meets it.
Windows and doors in Ardeer
Ardeer is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. With historic houses such as Montgreenan (about 4.5 miles north-east) nearby, there’s older building stock in the area around Ardeer as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Letting a property close to Stevenston station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For site and facilities teams at buildings such as Glencairn Primary School, the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Ardeer Church Of Scotland, the joint between an old wall and a newer frame is generally the first place rain gets in.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Look round the frames every year or so
- Wipe condensation off the frames
- Make sure the drainage slots aren’t blocked
- Avoid harsh chemicals near the mastic
Check the drainage slots in the frames are not blocked, so rain drains out rather than building up at the sealant.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.

How we quote for window mastic
For a quick quote, just ask. The main things that affect it are:
- How much there is to do
- Any working-time requirements on site
- Access and height
- The type of sealant required
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, drop us a line at info@mrmastic.co.uk and we will give you an honest view and a quote.
What we need to know
Before you ask for a quote, have a think about:
- Any access issues, like height or stairs
- Where the property is
- A few photos by email, if you can
- How many joints, rooms or windows are involved
We quote each job on its own. Just send an email to info@mrmastic.co.uk with the details, and pictures are welcome.
The process
On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. The work normally takes anything from an hour or two to a full day, depending on how many frames there are. Around Ardeer, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children

Advice
Common questions in Ardeer
Is Ardeer within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is window mastic in a coastal place like Ardeer any different?
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. It’s worth checking the walls that face the sea 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.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we are fully insured.
How long will my window job take?
The work takes anything from an hour or two to a full day, depending on how many frames there are. Access and how stubborn the old mastic is affect the time most.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Will new mastic stop draughts?
Often, yes. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
What happens if it’s left?
Getting a straight, even bead on an outside frame takes practice, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. In a place like Ardeer, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
