What affects the cost of window mastic
For a quick quote, just ask. The main things that affect it are:
- Access and height
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.

About our window mastic in Innermessan
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that can’t flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. Common call-outs are for rain getting in at the frame or under the sill and mastic that has split away from the wall, on composite doors, window sills and patio & French 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.
Whatever the size of the job, you get the same one-year guarantee in Innermessan and across Dumfries and Galloway.

What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes anything from an hour or two to a full day, depending on how many frames there are, including the tidy-up. 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.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about earlier repairs to the joints
- Mention any sign-in or site rules at work premises

Advice
Windows and doors in Innermessan
Innermessan 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Letting a property close to Stranraer station? Then renewing tired window mastic between tenants heads off draught and damp complaints. Around Innermessan, as everywhere, window mastic is only as good as the preparation behind it.

Different surfaces, different methods
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so they get particular care.
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.

How to look after the new joints
So the new joints stay in good condition:
- Clear any debris from frame drain holes
- Walk round the house once a year and look at the joints
- Do not paint over the silicone
- Keep timber frames painted
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just send an email to info@mrmastic.co.uk.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
Why act early in Innermessan
Running fresh sealant over the old joint is tempting, but new sealant can’t bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. The old mastic has to come out. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.

Common questions in Innermessan
Can you help a landlord with a rental near Stranraer station?
Yes, we work for landlords and letting agents. You can email us at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before we start.
Will you come out to Innermessan?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Can you get sealant to suit coloured frames?
Yes, we choose a colour to suit the frame. Grey and black frames get grey or black sealant, and wood-effect frames generally suit brown.
Is the work guaranteed?
Yes. Our one-year guarantee covers every job, inside or out.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little.
Can you reach windows above the ground floor?
Yes, where it’s safe. Higher or awkward frames may need extra access, and we will confirm what’s needed.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
Can I do it myself?
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, then guaranteed for a year.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
