Honest limits
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Draughts through the window seals rather than the frame
- Penetrating damp from a failed cavity tray or render
- A failed sealed unit that has misted up
If you’re not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.

About our window mastic in Lochranza
Over two decades of sealing frames has taught us which products suit which walls. We’re fully insured ARBOMaster approved applicators, and we give a one-year guarantee on the work. We work on aluminium frames, uPVC windows and timber windows & doors, and people most often call us about water coming in at the bottom corners of a door and cracked sealant at the sill ends.
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, whatever its size.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Repaint timber before it’s bare
- Clean frames with a soft cloth and soapy water
- Paint up to the joint, not over it
- Walk round the house once a year and look at the joints
Most silicone sealants won’t take paint, so mention any painting plans before we start. We can use a paintable sealant where that matters.
Leaks usually show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.

Can you reach windows above the ground floor?

How long does it take to reseal the windows on a house?
It depends on access, the old mastic and the size of the frames. You will know the timing when we quote.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
How long should I leave it?
It depends on the product and the conditions. Before we leave, we’ll tell you the cure time.

How we quote for window mastic
The quote reflects the job in front of us. We take into account:
- Whether the work is at height
- Which sealant suits the joint
- The old material and how stubborn it is
- How many areas need sealing
A few things move the cost up or down: how much old sealant there is and how stubborn it is, 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 ask for a quote, tell us:
- Access, such as stairs, a lift or height
- Photos by email, if that’s easy
- The type of property
- The problem you’ve noticed
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
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.
Window mastic in Lochranza: local notes
Lochranza is within about 1 mile of 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. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
If you live in an older home near Castlekirk, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Lochranza is about 20 miles west of Saltcoats, in North Ayrshire. Jobs in Lochranza get the same care as everywhere else we work: old sealant removed completely, careful preparation and a one-year guarantee. Our North Ayrshire coverage runs to 53 places, Lochranza among them. For nearby work, see our Glasgow page, about 41 miles away.
Work in KA27 works the same way as everywhere else we cover. Whether your property is on Bearlach Dearg and Newton Road or anywhere close by, our applicators can take on the job. If you are just outside Lochranza, we cover Pirnmill (6 miles south-west), Corrie (8 miles south-east), Whitehouse (10 miles north-west), Kingarth (11 miles east) and An Tairbeart (12 miles north-west). Island and remote addresses take a little more planning, so tell us where you are when you ask for a quote.

How the visit works
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the job takes most of a day for a typical house, less for a few frames in most cases. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work, 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.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Let us know about stairs, lifts or work at height
- Let us know about parking restrictions

Advice
When to call us in Lochranza
Mastic ages in the weather. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
These are the problems we’re asked about most:
- Cracked or shrunken mastic around the frame
- Mastic that’s falling out in pieces
- Water coming in at the bottom corners of a door
- Leaking joints at the ends of sills
In and around Lochranza, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
