DIY sealant or a professional job?
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.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

How the visit works
Every visit runs the same way: we check the joints, protect the area around them, do the work and tidy away. It generally takes a few hours for a few frames, or a day or more for a whole house. For a place like Heogan, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Getting ready for the visit

Surface by surface
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. We pay most attention there.
Signs you need window mastic in Heogan
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, while a joint packed solid cannot stretch. That’s what backing rod is for.
Any of these means the joints need attention:
- Gaps where the sill meets the wall
- Sealant in the wrong colour for the frame
- Gaps between the frame and the inside reveal
- Cracked or shrunken mastic around the frame
Schools such as Anderson High School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

What window mastic looks like in Heogan
Heogan is close to 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For an older house near a landmark such as St Margaret's Roman Catholic Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Why act early in Heogan
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts, so you know where you stand.
