Construction mastic in Harray
A typical mastic package covers more than window perimeters: frame perimeters inside and out, caulking to trims and boards where the specification calls for it, sanitary silicone, kitchens, and the final snag list. One contractor for all of it keeps the responsibility in one place. If you’re dealing with new external sealant already peeling away and existing joints on a refurb that need cutting out and resealing, we can put it right. Facilities teams, main contractors and managing agents in Harray tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Sites near smaller places like Harray can mean longer travel, so the mastic is planned with as few trips as the job allows. Clear drawings, a programme and photos let us bring the right sealants, primers and backing rod first time.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Sites and facades in and around Harray
Harray is within about 2 miles of the coast. Coastal exposure means perimeter and cladding joints work harder than on an inland job, and the sealant, primer and backing need choosing with that in mind. Scotland has its own building regulations, and in Harray warrants come from the local authority verifier. Our job is to seal to that specification.
On any site in or around Harray, the mastic follows the specification and the programme.
Harray is about 9 miles north-west of Kirkwall, in the Orkney Islands. Commercial clients in Harray can call on us for mastic packages, as part of our coverage of the Orkney Islands. Our the Orkney Islands coverage takes in 51 places.

Common questions from Harray clients
Can you keep pace with our programme in Harray?
Yes, we work to the programme and the sequence the site sets. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can you take on a job in Harray, on the island?
Yes, Harray is within the area we cover. Every Scottish council area is within our area. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.
Do your applicators hold CSCS cards?
We’re CHAS accredited and a Constructionline member, with CSCS-carded applicators. We’re also fully insured, with five million pounds of public liability cover.
Does weather affect external mastic work?
External mastic depends on conditions: the joint needs to be dry and within the product’s temperature range. We plan external elevations with that in mind.
How many days will you need on site?
That varies with the scale of the job, but the work typically takes a day or two on a small fit-out and several weeks on a large multi-storey package. For bigger or phased jobs, we’ll set out a timescale with the quote.
Can fire-rated sealing at service penetrations be included?
We install fire-rated sealant where it is the specified product. If the detail calls for collars, wraps or batts instead, we’ll tell you.
Can the sealant be colour-matched?
That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
What sealant work can’t fix
Honesty saves time and money. New sealant won’t cure:
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Frame gaps too wide for sealant, which the installer needs to correct
- Faulty frames rather than failed sealant
If you’re not sure, just call the office on 01277 525 020 or email us and we’ll give you a straight answer.
Joints and surfaces we work on
- Window and door perimeters
- Cladding and panel joints
- Internal decorators’ caulk
- Sanitary and kitchen joints
- Brick and block movement joints
- Floor and skirting junctions
Different surfaces, different methods
Window and door perimeters
Internal perimeters are usually sealed with a paintable product where decorating follows. The specification decides which.
External facade and movement joints
Movement joints in the facade are sealed with a product suited to the expected movement. We set the depth with backing rod to avoid three-sided adhesion.
Diagnose, treat, sign off
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For work around Harray, we aim for one trip, so photographs, sizes and a full list matter. Outside work also needs a suitable weather window.
- Drawings, the sealant specification and your programme come to us for pricing.
- You receive a fixed quote listing scope, products and phasing.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- We seal each plot or floor as it’s released to us.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
Getting the site ready
- Tell us which areas need to stay in use
- Let us know about inductions and permits

What sets the cost
These are the things that shape the price:
- Travel to remote or island sites
- Backing rod, priming and other preparation
- Quantities, in metres or numbers
- Induction, permit and paperwork requirements
Pricing mastic packages depends on quantities, condition and access. Call for a quote.
Details that help us quote
There’s no need for a formal survey. A few details are enough to get going:
- Approximate linear metres or a joint schedule
- Asbestos survey details if the building is older
- What the building is and how it’s used
- Photos of the joints, close up and from further back
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call the office on 01277 525 020 or send photos by email.
Why it’s worth doing now in Harray
Getting the mastic contractor involved early pays off. We can check joint widths, flag frames with gaps that won’t seal and confirm products against the specification rather than at the snagging stage. Called in at the end, the same issues surface during handover. Around smaller places like Harray, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Resealing early avoids that.
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What we are called out for in Harray
A new building moves while it dries and settles. Plaster, screeds, timber and blockwork all shrink as they lose moisture. Picking a flexible sealant where there’s movement keeps snags down.
Things that normally lead to an enquiry:
- Missed perimeter joints on a new elevation
- Caulk cracking where joints are moving more than expected
- Old sealant on a refurbishment that needs stripping before new work
- Frame gaps too wide for sealant alone
Around Harray, as anywhere, a facade joint depends on its sizing, backing rod and preparation.
