Construction Mastic in Hoy
Sealant work in Hoy for main contractors, managing agents and facilities managers: mastic packages for new-build and refurbishment projects, quoted at a fixed price.
- Existing joints on a refurb that need cutting out and resealing
- Mastic snags holding up handover
- Bath and shower joints scraped during the final clean
Construction mastic for Hoy sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
From enquiry to sign-off
At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Travel to smaller Scottish places like Hoy is planned so the job is finished in one visit where possible, so photos, sizes and a full list matter. External joints need a dry spell as well.
- We start with the drawings, specification and programme.
- Quantities are measured and a fixed price returned.
- The sequence is agreed with the site manager.
- Plots or floors are sealed as they’re handed over.
- Every joint is cleaned, set to depth and sealed with the specified product.
- Snags are cleared and the package signed off with our 12-month guarantee.
Preparing the site
- Arrange parking or a loading space
- Tell us which areas need to stay in use
- Share your working hours and any access restrictions
Ask for a quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

Construction mastic in Hoy
We work to the specification and the programme rather than whatever product is to hand. Where the specification names a product, we use it. Joint widths, backing, primers and tooling follow the manufacturer’s guidance, so the joints perform as the designer intended. If you are dealing with frame perimeters left unsealed or poorly sealed and a mastic package split between trades with no clear owner, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Hoy is the same: the right product in a properly prepared joint.
In smaller places such as Hoy, 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.
A 12-month guarantee applies to all our work in the Orkney Islands. Should something we installed fail, ring 01277 525 020 or email drawings and photos and we’ll come back to it.

When it isn’t the sealant
Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:
- Faulty frames rather than failed sealant
- Deciding which fire-stopping product a penetration needs
- Joint design decisions that belong to the architect or engineer
Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we’ll tell you honestly.
Joints and surfaces we work on
- Cladding and panel joints

- Internal decorators’ caulk
- Floor and skirting junctions
- Window and door perimeters
Doing it in-house
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.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Leave it or put it right?
A cheaper sealant can look like an easy saving on a large package. The saving is small next to the cost of callbacks and defects and external joints are where it shows first. Where an alternative is genuinely suitable, we will say so. Around smaller places like Hoy, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Resealing early avoids that.
A quote for mastic packages depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

Signs you need construction mastic in Hoy
Value-engineered products sometimes end up in the wrong joints. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We use what’s specified, and any substitute goes to you for acceptance.
Things that usually lead to an enquiry:
- Mastic snags holding up handover
- Internal caulk splitting as the building dries out
- Sanitary sealant damaged by following trades
- Early adhesion failures on new external joints
On a campus such as Robert Gordon University Orkney Project, 3.7 miles to the north of Hoy, new teaching buildings and residences are typically built and refurbished around the academic year.
What to look for in a quote
- Which product they’ll use, and why it suits the joint
- Their pre-qualification and accreditations
- Their approach to joint depth and backing
- Whether primer will be used where the manufacturer specifies it
Questions we’re asked in Hoy
Will you plan work around the academic year at somewhere like Robert Gordon University Orkney Project?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Does the sea air around Hoy change the choice of 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 stick to the specified products?
Specification first, then the maker’s instructions. Primers, backing and joint depth follow what the manufacturer sets out.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
What site paperwork can you supply?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
Does the weather affect the work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Work for main contractors and building owners
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Construction mastic around Hoy: points for this area
Hoy sits close to the coast, within about 1 mile. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. For an island location such as Hoy, work is planned around ferry crossings and the weather. Drawings and the programme let us bring every sealant, primer and backing rod the package needs.
For contractors building in or near Hoy, we seal to the drawings, the specification and the programme.
