When to call us in Dunure
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
If you can see any of these, it’s time to have the joints looked at:
- Draughty joints inside around the window
- Whistling draughts around closed windows
- Gaps left after new windows were fitted
- Mastic that has split away from the wall
Rented homes near Maybole station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.
Questions to ask before you book
- What happens if the job turns out different
- Is VAT in the price?
- Who does the work, and how experienced they are
- What guarantee comes with the work
Window mastic for homes and businesses in Dunure
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through. If the draught is through the window seals instead, we’ll tell you. We’re often asked to deal with untidy mastic left by window fitters and whistling draughts around closed windows, across timber windows & doors, aluminium frames and window sills.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Every job comes with our one-year guarantee.

Questions from Dunure
Is Dunure within the area you cover?
Yes, Dunure is covered. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Does living near the coast affect window mastic in Dunure?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Will the old sealant be removed?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
When is the sealant fully cured?
Cure times vary by product and the conditions. Before we leave, we will tell you the cure time.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Is the new sealant paintable?
It depends on the sealant. Silicone is not paintable, but some hybrid sealants are. Mention any painting plans before any work starts.
Can you match the sealant to my frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available, so the joint suits the frame.
How long will my window job take?
It depends on access, the old mastic and the size of the frames. We will tell you how long your job needs when we quote.
For landlords and businesses
We also work for property managers and facilities teams in Dunure and across South Ayrshire. Several sites can be quoted together, and we are fully insured for the work.
Landlords and agents in Dunure can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Different surfaces, different methods
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. We match the colour to the frame.
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.

How we quote for window mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- The old material and how stubborn it is
- How easy the joints are to reach
- The product the joint needs
- How many rooms, windows or areas are involved
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’ll know the price before we begin.
Helping us quote
To make quoting easier, let us know:
- What’s wrong with the joints now
- Where the job is, and your postcode
- Any previous sealing or DIY work
- Any access issues, like height or stairs
We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, drop us a line at info@mrmastic.co.uk.
Windows and doors in Dunure
Dunure 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Homes close to Kirkbride Old Parish Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep drainage slots and sill grooves clear
- Keep paint and stain on wooden frames in good order
- Don’t aim a pressure washer at the joints
- Check the mastic once a year
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. A new joint closes it up.
The process
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for a few frames, or a day or more for a whole house for a typical job. Outdoor work around Dunure 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 go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Keep children and pets away from the work area
- Clear the area around the work
- Tell us about any previous sealing or DIY attempts
