Construction mastic across Widewall
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
On site: what to expect
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. For a building near Widewall, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.
- First we take quantities off the drawings and read through the specification.
- 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.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- We close out snagging and hand over with a 12-month guarantee.
What we need from you
- Clear stock, furniture or equipment away from the joints
- Have the specification and drawings to hand
- Flag any permit to work we will need
Ask for a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

About our construction mastic in Widewall
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old, and on older buildings we ask for the asbestos survey before disturbing anything. New and existing joints then get the same preparation. If you are dealing with sealant knocked or painted over by other trades and internal caulk splitting as the building dries out, we can help. Most enquiries from Widewall start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
External sealing around Widewall depends on dry faces and the right temperature. We build some give into the plan and agree it with the site manager.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Different surfaces, different methods
Kitchens and utility areas
Worktop upstands, sinks and splashbacks are sealed once the kitchen is fitted. A kitchen-suitable sealant is used, food-safe where food contact is possible.
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. Fire stopping design belongs to the designer and building control; we work to the specification and the manufacturer’s installation guidance.
Commercial clients in Widewall

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Why deal with it now?
Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. Sound frames often need only a new perimeter seal. If the frame is life-expired, we will tell you. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, giving water time to get in. Early resealing prevents it.
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.

Building and refurbishing in Widewall
Widewall is within about 1 mile of the coast. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. Projects in Widewall follow Scotland’s building regulations, with the local authority acting as verifier. The mastic package follows the approved specification.
Around Widewall, as anywhere, a facade joint depends on its sizing, backing rod and preparation. For contractors building in or near Widewall, we seal to the drawings, the specification and the programme.
Widewall is about 12 miles south of Kirkwall, in the Orkney Islands. Widewall sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. We work across 51 places in the Orkney Islands, large and small.
Postcode districts covered here: KW17. Access to Widewall is via the B9042 among other routes. We also cover St Margaret's Hope (2 miles north-east), Grimness (3 miles north-east), Burray Village (4 miles north-east), St Mary's (7 miles north) and Lyness (8 miles west) for mastic packages. Remote and island addresses take more planning, from travel and ferries to the weather, so mention the location when you call the office on 01277 525 020 or email drawings and photos.

What sets the cost
There’s no standard rate for sealant work, because every site is different. What we look at:
- Whether old sealant has to be cut out first
- The site’s rules and procedures
- Quantities, in metres or numbers
- Any access equipment needed
A quote for mastic packages depends on quantities, condition and access. Call for a quote.
What to include in your enquiry
However big the job, these details speed things up:
- Specification clauses that apply
- A wide shot and a close-up of the area
- Approximate linear metres or a joint schedule
- Whether the building will be occupied during the work
A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or call 01277 525 020 or email drawings and photos if you’d rather talk the job through.
Your questions answered
Can you work to our programme on a site in or near Widewall?
Yes. The mastic is planned around your key stages. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is Widewall inside the area you cover, given it’s on an island?
Yes. Islands are part of our area, Widewall included. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.
What about RAMS and site documents?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
Can you work to our specification?
Specification first, then the maker’s instructions. Preparation, backing and depth follow the product guidance.
What happens if the weather stops external sealing?
External sealant needs a dry joint and a temperature within the product’s range. Damp, frost or condensation on frames can stop work so we usually switch to internal work when that happens.
How do we ask for a quote?
The quote form is the simplest route, though you can also call the office on 01277 525 020 or use the quote form. Include photographs or drawings if you have them.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

What sealant work can’t fix
Honesty saves time and money. New sealant won’t cure:
- Damage to finishes by other trades after we have sealed
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Frame gaps too wide for sealant, which the installer needs to correct
Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we will tell you honestly.
