Questions from Braehoulland
Does living near the coast affect window mastic in Braehoulland?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do you cover smaller places like Braehoulland?
Yes, Braehoulland is covered. We work across all of Scotland, islands included, from towns to the smallest places. Longer journeys are simply planned in advance.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme.
How many windows can you do in a day?
Allow a few hours for a handful of frames, longer for a whole house. Access and how stubborn the old mastic is affect the time most.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Do you work for landlords and businesses?
Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.
How much does window mastic cost in Braehoulland?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Window mastic in Braehoulland, done properly
The new joint does not have to be white. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. If you are dealing with rushed sealant from a window installation and draughts coming in around windows and doors, we can help, on aluminium frames, window sills and composite doors alike.
Mastic can only go onto a dry joint, so outside work in Braehoulland depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
Every job comes with our 12-month guarantee, wherever you are in the Shetland Islands.

Why deal with it now?
Running fresh sealant over the old joint is tempting, but new sealant cannot bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. In an older home around Braehoulland, damp from a failed joint can get into timber and plaster.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

Landlord and commercial work in Braehoulland
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
We also work for property managers and facilities teams. Several sites can be quoted together, and we’re fully insured.
Signs you need window mastic in Braehoulland
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. Backing rod sets the right depth.
These are the problems we’re asked about most:
- Untidy mastic left by window fitters
- Hard, cracked sealant around windows
- White mastic on grey or black frames
- Cracked sealant at the sill ends
Whether the job is in Braehoulland itself or nearby, the right material for each joint matters as much as a neat finish.

How it works
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take most of a day for a typical house, less for a few frames. Outdoor work around Braehoulland depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.

Braehoulland 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 is hard on the mastic around window and door frames, especially on the side facing the sea. On the islands, wind and salt spray are hard on outside sealant.
Around Braehoulland, as everywhere, window mastic is only as good as the preparation behind it.
Braehoulland is about 28 miles north-west of Lerwick, in the Shetland Islands. Whether you are in the middle of Braehoulland or further out, window mastic is available for homes and businesses alike. Braehoulland is one of 63 towns and villages in the Shetland Islands we cover.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Surface by surface
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. Each is cleaned, backed where deep and resealed.
Composite doors
Draughts round the door leaf generally come from worn seals or adjustment, not the mastic. We’ll tell you if that is what we find.
Aftercare tips
A little care helps the new joints last. We recommend:
- Walk round the house once a year and look at the joints
- Clear any debris from frame drain holes
- Air rooms to keep condensation down around windows
- Do not use solvent cleaners on the joint
A yearly look round the frames is enough. Small splits are simple to catch before they leak.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
