Window mastic in Holm: local notes
Holm 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. Holm is in the west of Scotland, which is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain.
In and around Holm, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Window mastic in Holm, done properly
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. Common call-outs are for leaking joints at the ends of sills and old mastic that has gone black or come away, across patio & French doors, timber windows & doors and uPVC windows.
Mastic can only go onto a dry joint, so outside work in Holm depends on the weather. Tell us about access to all the windows and doors, upstairs included.
There’s a 12-month guarantee on every job, large or small.

Surface by surface
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
What we do, step by step
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for a handful of frames, longer for a whole house. For a place like Holm, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- 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.
Before we arrive
- Mention any tricky access
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work

Advice
Common questions in Holm
Is window mastic in a coastal place like Holm any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Will you come out to Holm?
Yes. Holm is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland, including the islands, where work is planned around ferry crossings. Just mention lanes, gates or anything else about the route when you book.
Do you have sealant for grey or black windows?
Yes, we choose a colour to suit the frame. Grey and black frames get grey or black sealant, and wood-effect frames normally suit brown.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used before we leave.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
How long will my window job take?
It depends on access, the old mastic and the size of the frames. We will tell you how long your job needs when we quote.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

What we are called out for in Holm
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, and a gap filled solid can’t flex. That is what backing rod is for.
Signs it’s time to call us include:
- White mastic on grey or black frames
- Water coming in at the bottom corners of a door
- Untidy mastic left by window fitters
- Draughts coming in around windows and doors
For jobs in and around Holm, choosing the right material for each joint is as important as a tidy finish.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then 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.
