Window mastic in Joppa
Over two decades of sealing frames has taught us which products suit which walls. We’re ARBOMaster approved and fully insured, and we give a 12-month guarantee on the work. Common call-outs are for sealant in the wrong colour for the frame and cold air getting in at the frame edge, across aluminium frames, uPVC windows 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.
Big or small, it’s backed by our 12-month guarantee.

What affects the cost of window mastic
Every job gets its own quote. This is what makes a difference:
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
- Which sealant suits the joint
What it costs depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.
Asking for a quote
When you contact us, these details help:
- The rough size of the job
- Whether it has been sealed before
- The type of property
- A few photos by email, if you can

What we’re called out for in Joppa
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
Any of these means the joints need attention:
- Hard, cracked sealant around windows
- Rain getting in at the frame or under the sill
- Sealant in the wrong colour for the frame
- Leaking joints at the ends of sills
Homes close to Coylton Parish Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What your quote should include
- What product goes in the joint
- Are they insured?
- The length of the guarantee
- Whether all the old sealant comes out first
Joppa questions
Can you do window mastic in Joppa?
Yes. We work across all of Scotland, and Joppa is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear price.
Do you work for landlords with property near Ayr station?
Yes, landlords and agents are among the people we work for. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Are you insured?
Yes. We’re fully insured.
Can you seal the gap between the frame and the plaster indoors?
Yes. Plenty of draughts come through the inside joint as well as the outside, so it can be worth sealing both.
How long will my window job take?
A handful of frames is a short visit. We confirm the timing with your quote.
Can you get sealant to suit coloured frames?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What we can’t put right
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- A frame that has rotted at the joint
- Draughts through the window seals rather than the frame
- A failed sealed unit that has misted up
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly before booking.

Work for landlords, hotels and businesses
If you manage several properties in or around Joppa, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
Joppa homes and the weather
The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out. 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.
Letting a property close to Ayr station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

What else we do in Joppa
What the job involves on each surface
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so they get particular care.
Window sills
Where a sill meets brick or render, the ends often crack first. A tight seal at each end keeps rain out of the wall.
How it works
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a morning for a couple of windows and a door. Around Joppa, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed
