Mastic sealing in Greenock, done properly
Owners and agents normally inherit a building’s mastic rather than choose it and it slowly wears out: window perimeters, door frames, external joints and communal junctions all rely on it. Once it cracks, hardens or comes away, draughts and water find a way in along with complaints. We work on communal entrances and stairwells, external wall and movement joints and balcony and threshold joints, and what we are called in for most is damp patches beside frames and draughts at frames across a block. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Greenock is the same: the right product in a properly prepared joint.
Owners with several buildings in a town like Greenock can group mastic work into one programme. We move block by block once you’ve told residents what to expect.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Looking after the joints
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Include mastic in your cyclical inspections
- Encourage occupiers to report problems at frames
- Share your contractor requirements early
- Plan resealing building by building rather than complaint by complaint
Log the date and extent of the resealing for each block. That makes future programmes easier to plan and gives you a history.
Left open, joint edges in render, brick or frames can deteriorate. Once that happens, repairs come before resealing.

Common questions from Greenock clients
We manage a building near Drumfrochar station. Can you help?
Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.
Does a coastal location like Greenock affect which sealant is used?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
What if the old mastic contains asbestos?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
Will residents or tenants be disturbed?
We plan around people living or working in the building. We agree the programme so you can notify occupiers, and entrances stay in use.
Do you guarantee the mastic work?
There is a 12-month guarantee on our workmanship, backed by public liability insurance.
Can you take on resealing for a block portfolio?
Yes. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.
Site staff or a sealant specialist?
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Blocks and managed buildings in Greenock
Greenock sits close to the coast, within about 1 mile. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints, and they deserve more regular inspection. The west of Scotland, where Greenock is, gets more rain than the east. Exposed elevations on blocks take a soaking and their mastic shows it. We plan block programmes with the forecast in mind.
If your remit includes a building such as Wellington Academy, frame and door mastic can be programmed for the holidays. Landlords with units on estates such as Cappielow Trade Park (to the east of Greenock) can bring frame, door and external mastic across several units into one programme.

Do you need mastic sealing in Greenock?
Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and splits as the building moves.
If one of these sounds familiar, it’s time for a closer look:
- Window mastic that has split and shrunk
- Damaged joints in communal entrances and corridors
- Water getting in round frames after rain
- Movement joints with sealant missing
If you look after a block within reach of Drumfrochar station (under half a mile south-east of Greenock), frame and balcony mastic can be renewed on one programme.
Before you book anyone
