Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
About our window mastic in Arniston
The new joint does not have to be white. 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 cracked sealant at the sill ends and cold air getting in at the frame edge, we can help, whatever the surface.
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.
There’s a 12-month guarantee on every job, large or small.

What happens on the day
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from an hour or two to a full day, depending on how many frames there are. For a place like Arniston, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints
- For indoor joints, keep the area dry beforehand if you can

Windows and doors in Arniston
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
If you let a flat or house near Gorebridge station, renewing tired window mastic between tenants heads off draught and damp complaints.

Your questions about window mastic in Arniston
Do you cover smaller places like Arniston?
Yes, Arniston is covered. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
I let a flat near Gorebridge station. Can you help?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Can I do 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.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you when we finish.
How many windows can you do in a day?
A handful of frames is a short visit. You will get a timescale with the quote.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
When to call us in Arniston
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, so it comes away long before its time.
Keep an eye out for these signs:
- Cold air getting in at the frame edge
- Mastic that is falling out in pieces
- Gaps between the frame and the inside reveal
- Cracked or shrunken mastic around the frame
Homes close to Hunterfield Road Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.
What to look for in a quote
- Whether you can choose the colour
- What happens if the job turns out different
- Who turns up on the day
- How the surfaces are prepared before sealing
Why deal with it now?
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. In an older home around Arniston, damp from a failed joint can get into timber and plaster.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Why book with us
- Neat joints and a tidy finish
- Homes, businesses and hotels
- We never seal over old sealant
- An ARBOMaster approved applicator

What the job involves on each surface
Composite doors
Front doors take the weather head on. Those corners get the most care.
Aluminium frames
Aluminium needs a sealant that bonds to coated metal. We use a neutral-cure product.
