Mastic sealing for Carloway sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
When to bring in a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
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. That’s why many clients bring in a specialist from the beginning.
How we handle mastic sealing in Carloway
For blocks and buildings in Carloway and across Na h-Eileanan Siar, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote or we can visit. If you’re dealing with repeated reactive repairs to the same buildings and brittle perimeter mastic across a building, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in Carloway it comes down to the same thing: the right product in a properly prepared joint.
In smaller Scottish places like Carloway, managed property is mostly small blocks, sheltered housing, hotels and community buildings. Frames on exposed elevations are where mastic usually fails first.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

For owners and agents in Carloway
Carloway sits close to the coast, within about 2 miles. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first. Carloway is in the west of Scotland, the wetter side of the country. The weather side of a block usually needs attention first. External work is booked for dry spells, with a little give in the dates.
Wherever your building is in or near Carloway, we look at the whole elevation before quoting, so you know what needs doing now.
Carloway (Gaelic: Càrlabhagh) is in Na h-Eileanan Siar. Any commercial site in Carloway is covered. Our Na h-Eileanan Siar coverage takes in 87 places, from busy centres to rural villages.

How the quote is worked out
What shapes the price:
- Specialist products, such as fire-rated or hygienic sealants
- How accessible the joints are
- Location, for remote and island sites
- Whether old sealant has to be cut out first
The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Sending details for a quote
A good diagnosis starts with the right details. Let us know:
- Anything awkward about access or site hours
- Any dates the work must fit around
- Photos of the joints, close up and from further back
- Rough lengths or quantities, or drawings if you have them
Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, call the office on 01277 525 020 or use the quote form.
Why it’s worth doing now in Carloway
Draughts round window perimeters cost occupiers comfort and the windows usually get the blame. In many cases, new perimeter sealant deals with it where the frames themselves are sound. For buildings near Carloway, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
What you get with us

What we can’t put right
We check first that sealant really is the fix. It isn’t the answer for:
- Leaks through the frame itself rather than the perimeter
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Water coming in from the roof or rainwater goods
Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Balcony and threshold joints
- Communal entrances and stairwells
- Window and door perimeters on blocks
- Shopfronts below residential blocks
- External wall and movement joints
- Communal kitchens and washrooms

Other services in Carloway
Do you need mastic sealing in Carloway?
We often find joints filled solid with no backing rod, so the mastic is glued to the joint bottom too. That three-sided adhesion stops it stretching and splits as the building moves.
Any of the following is a good reason to get the joints checked over:
- Mastic failing across several blocks on an estate
- Failed external movement joints
- Draught complaints from residents or tenants
- Communal area joints that look neglected
For owners and agents with buildings in or around Carloway, block-wide mastic programmes deal with frames and external joints of the same age together.
What to look for in a quote
- Their approach to joint depth and backing
- Whether primer will be used where the manufacturer specifies it
- The named product and why it was chosen
- Can the work be phased to keep areas open?
Carloway: questions and answers
Will you price a mastic programme across our Carloway portfolio?
Yes. Portfolio-wide programmes are a regular request. Send the addresses and photos and we will give a fixed quote.
Will you travel to Carloway on the island?
Yes. We work across every Scottish council area, and that includes island locations such as Carloway. We group island work where we can and plan around the crossings.
Can you send RAMS and CSCS details before starting?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
How long does a typical visit take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
How do you handle work on occupied blocks?
Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Diagnose, treat, sign off
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For work around Carloway, we aim for one trip, so photos, sizes and a full list matter. External joints need a dry spell as well.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
What we need from you
- Move anything stored against the joints
- Tell us which areas need to stay in use
- Send asbestos survey details if the building is pre-2000
