Facade sealing for commercial buildings in Castlebay
Installing framed glazing systems isn’t part of our work. We handle the sealant joints that surround those elements: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds with products suited to facade or glazing perimeter joints. If you have hard, chalky sealant that no longer flexes and new sealant peeling off old mastic, we can help. For commercial sealant work in Castlebay, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Castlebay that means watching the forecast. We build some give into the plan and agree it with the site manager.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

- Damp caused by condensation inside the building

How a job runs
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. Travel to smaller Scottish places like Castlebay is planned so the job is finished in one visit where possible, so photographs, sizes and a full list matter. Outside work also needs a suitable weather window.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- The existing bead comes out in full and both faces cleaned back.
- Primer goes on where the product data asks for it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- We go over the completed work with you before leaving.
Getting the site ready
- Flag any permit to work we will need
- Share your working hours and any access restrictions
- Make sure the joints can be reached

What the job involves on each surface
Cladding panel joints
Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish, often a low-modulus silicone or hybrid.
Precast concrete panels
Precast arrises sometimes crumble or carry old residue. Faces are cleaned to sound concrete, and damaged edges are reported first.

What else we do in Castlebay
Sites and facades in and around Castlebay
The sea is no more than about 1 mile from Castlebay. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so we check the specified product suits the exposure before the first bead. For an island location such as Castlebay, work is planned around ferry crossings and the weather. Everything for the package travels with us, so drawings and quantities matter.
Hotels like Castlebay Hotel, under half a mile north-west of Castlebay, rarely close for long, so refurbishment mastic is phased floor by floor. New wings at hospitals like St Brendan's Hospital (to the south-west of Castlebay) bring long runs of window and panel joints to seal.
Castlebay is in Na h-Eileanan Siar. Across the HS9 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Across Na h-Eileanan Siar, 87 places are covered, Castlebay among them.

Quoting for work in Castlebay
Each job is priced on its own details. The main factors are:
- Phasing around occupants
- Location, for remote and island sites
- The size and state of each joint
- The site’s rules and procedures
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
Sending details for a quote
We can often quote from photographs and a few details. It helps to include:
- Photos of the joints, close up and from further back
- The product your specification calls for
- What the building is and how it’s used
- Approximate linear metres or a joint schedule
Pricing a project or setting a maintenance budget? We will quote against your scope and drawings you can plan around. For a chat about it beforehand, call 01277 525 020 or use the quote form.
When to call us in Castlebay
Product choice matters: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Most external joints call for a neutral-cure, facade-grade sealant.
Any of the following is a good reason to get the joints checked over:
- Weathered joints at frame-to-structure perimeters
- Old perimeter mastic that has dried out
- Air leaks through failed facade joints
- Water coming in around window frames
School extensions, at buildings such as Castlebay Community School, normally run to the summer holidays, mastic included.
What to look for in a quote
- Whether old or failed sealant will be cut out, not overlaid
- How they’ll work around occupants
- Their approach to joint depth and backing
- Which product they’ll use, and why it suits the joint
Castlebay: questions and answers
Is a hospital such as St Brendan's Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Will you travel to Castlebay on the island?
Yes, Castlebay is within the area we cover. We work across every Scottish council area. Island work is planned around ferry crossings and the weather, so photographs and a full list before we travel are essential.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.
Will you check whether the sealant is causing the leak?
Yes. Photos help, and you can speak to us on 01277 525 020 or email the details over to arrange a visit. Failed perimeter sealant is a common cause, but not the only one, and we’ll be honest about which it is.
Do you seal facades in winter?
Wet joints or temperatures outside the product’s range mean waiting. We plan for weather and keep you updated throughout the job.
What’s the quickest route to a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
When is resealing likely to be due?
Nobody can honestly give a figure in years, 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.
Aftercare for building managers
Cleaning and maintenance staff play a part too. Pass these on to them:
- Record the product and colour used on each elevation
- Brief window cleaners about newly sealed joints
- Don’t wait for a second leak before calling
- Inspect facade joints on a regular cycle
Keep a note of which product went in and when. It helps when matching repairs or planning the next reseal.
Coordinate facade sealing with other external works. One set-up for several trades saves money.
