Facade sealing in Portvoller
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
When to bring in a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
How we handle facade sealing in Portvoller
We don’t install glazing systems or replace glass. We handle the sealant joints that surround those elements: perimeter joints where frames meet the structure, panel joints and window perimeters. If you have staining on stone next to old sealant and air leaks through failed facade joints, we can help. For commercial sealant work in Portvoller, you deal with one contact from quote to sign-off, whether it’s one building or several.
In smaller places such as Portvoller, building work tends to be single schemes rather than big developments. Exposed elevations in Scotland put facade and perimeter joints to work from day one, so the sealant choice matters.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Questions about Portvoller
Can you keep pace with our programme in Portvoller?
Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Does the sea air around Portvoller change the choice of sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Can you send site paperwork?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.
Do you replace failed glazing units?
No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, including perimeters where frames meet the structure.
When is resealing likely to be due?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Can you find out why a window is leaking?
Yes. Photos help, and you can call the office on 01277 525 020 or email drawings and photos to arrange a visit. Many frame leaks are sealant failures, though not all, and we’ll tell you which.
Is colour matching possible?
It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

Leave it or put it right?
Open facade joints also let air and dirt through: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak. For buildings near Portvoller, dealing with all the failing joints at once saves return trips. Send photographs and we will quote for everything together.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What we’re called out for in Portvoller
Adhesive failure, where the sealant peels away from one face, typically comes from poor preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly, and the joint opens with the first real movement.
Look out for the following:
- Failed seals around shopfront and entrance frames
- Cold air coming in at window perimeters
- Failed sealant on precast panel joints
- Hard, chalky sealant that no longer flexes
Projects at schools like Aird Primary School work to term dates, so mastic is programmed tightly.
Comparing quotes
- Will failed sealant be removed rather than covered?
- Whether their applicators hold CSCS cards
- The named product and why it was chosen
- Can the work be phased to keep areas open?
What we can’t put right
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Joints whose design needs changing by the specifier
- Damaged frames that need replacing
- Leaks from roofs, gutters or failed flashings rather than sealant joints
Not sure which it is? You can ring 01277 525 020 or send photos by email and we’ll tell you honestly.

Building and refurbishing in Portvoller
Portvoller is within about 1 mile of the coast. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. Being on an island, Portvoller means planning around ferry times as well as the weather. With drawings and the programme in hand, the whole mastic package comes with us.
Sites around Portvoller get mastic sealed to the drawings and the programme, nothing improvised.
