Facade sealing across Carloway
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Your questions answered
Our building in Carloway is near the coast: does that change the sealant?
It can. Coastal exposure works external joints harder than inland weather. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Will you fit the mastic around our build programme in Carloway?
Yes. The mastic is planned around your key stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Do you provide access for facade work?
Access is planned with you before we quote. Tell us about access: existing scaffold, what you’re arranging and any site restrictions, and we’ll price the work around it.
Do you replace failed glazing units?
No. A glazing contractor handles that. We reseal window perimeters, panel joints and frame-to-structure perimeters.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Facade sealing in Carloway, done properly
Access is part of every facade job, and we plan it with you before quoting. Let us know what access exists or is planned, and any site rules we need to work around, so the price covers the real job. If you’re dealing with gaps between rainscreen or cladding panels and weathered joints at frame-to-structure perimeters, we can help. For commercial sealant work in Carloway, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
In smaller places such as Carloway, 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.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

When to call us in Carloway
When sealant lets go of a frame or panel, the cause is often the preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly, and movement soon pulls it away.
Site and facilities staff are often the first to spot these:
- Staining on stone next to old sealant
- Old perimeter mastic that has dried out
- Facade joints cracked through the middle
- Draughts around frames and panels
For contractors building in or near Carloway, we seal to the drawings, the specification and the programme.
What your quote should include
- What the guarantee covers, and for how long
- Will RAMS and insurance details be available?
- Are they CHAS accredited or on Constructionline?
- How they’ll work around occupants
What sets the cost
We price every job individually. The main factors are:
- Phasing around occupants
- How accessible the joints are
- Induction, permit and paperwork requirements
- The size and state of each joint
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
Sending details for a quote
Diagnosis starts before we arrive. Let us know:
- Asbestos survey details if the building is older
- Photos of the joints, close up and from further back
- Access details, including height
- Whether the building will be occupied during the work
A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or phone 01277 525 020 or send photos by email if you’d rather talk the job through.
Building and refurbishing in Carloway
Carloway lies within about 2 miles of the sea. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so joint design, primers and product choice deserve extra care. Being on an island, Carloway means planning around ferry times as well as the weather. Everything for the package travels with us, so drawings and quantities matter.
Around Carloway, as anywhere, a facade joint depends on its sizing, backing rod and preparation.

Surface by surface
Coping and flashing joints
Where the specification calls for sealant at copings or flashings, we can seal them. These joints take full exposure to weather.
Precast concrete panels
Precast arrises sometimes crumble or carry old residue. We clean back to sound material and flag edges that need repair before sealing.

Keeping the joints sound
Regular inspection catches problems early. In particular:
- Investigate damp beside windows promptly
- Avoid patch repairs on failed facade joints
- Inspect facade joints on a regular cycle
- Share access with other external trades
Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead and tell your cleaning contractor.
Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail instead of after the damage.
Owners, agents and contractors
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Diagnose, treat, sign off
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. For a building near Carloway, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.
- Access, site rules and timing are settled with the client up front.
- Weather and temperature are checked against the product’s limits.
- Each joint is cut out and the edges inspected.
- Faces are cleaned, primed where needed and backed.
- Sealant is gunned in and tooled hard onto both faces.
- Once signed off, the work carries our 12-month guarantee.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Agree which areas must stay open
- Let us know about inductions and permits
