About our window mastic in Kirkcolm
Colour matters on a frame. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. If you have black, perished sealant on frames and water coming in at the bottom corners of a door, we can put it right, on uPVC windows, aluminium frames and window sills alike.
Outdoor sealant needs a dry surface, so window work around Kirkcolm is planned around the weather. Let us know about access to every frame, including any upstairs.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

How the job changes by surface
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, 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.
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so they get particular care.
What window mastic looks like in Kirkcolm
Kirkcolm 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.
Rented homes near Stranraer station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What else we do in Kirkcolm
Why deal with it now?
A quick bead over the top of old mastic looks like an easy fix, but it won’t grip old, dirty sealant. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Around Kirkcolm, water from a failed joint in an older stone home can soak into timber and plaster.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.

FAQs for Kirkcolm
Does the coastal weather in Kirkcolm affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
I let a flat near Stranraer 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 we start.
Do you seal inside as well as outside?
Yes. Indoors, we seal between the frame and the plaster or reveal.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
How the visit works
Before we leave, we go over the finished joints with you. The visit itself usually takes a morning for a couple of windows and a door, depending on the size of the job. Outdoor work around Kirkcolm depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Before we arrive
- Keep children and pets away from the work area
- Move anything stored near the joints

Advice
Landlords, agents and businesses in Kirkcolm
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can go on one quote.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Keep jet washers away from the mastic
- Check the mastic once a year
- Keep drainage slots and sill grooves clear
- Air rooms to keep condensation down around windows
Check the drainage slots in the frames are not blocked, so rain drains out rather than building up at the sealant.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.

What we are called out for in Kirkcolm
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, and a gap filled solid can’t flex. Backing rod sets the right depth.
It’s worth asking for a quote if you see:
- Cracked sealant at the sill ends
- Sealant in the wrong colour for the frame
- Cold air getting in at the frame edge
- Gaps between the frame and the inside reveal
Around Kirkcolm, as everywhere, window mastic is only as good as the preparation behind it.
