Mastic sealing in Cullivoe
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Honest limits
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:
- Masonry that has broken away beside the joint
- Water coming in from the roof or rainwater goods
- Failed window or door frames, which need a window contractor
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
- Window and door perimeters on blocks
- Communal kitchens and washrooms
- Communal entrances and stairwells
- External wall and movement joints
- Balcony and threshold joints
- Shopfronts below residential blocks
Mastic sealing in Cullivoe, done properly
Across Cullivoe and the rest of the Shetland Islands, we work the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Addresses, photos of typical joints and a rough idea of quantities let us give a quick quote, and site visits can be arranged. The enquiries we see most involve failed external movement joints and occupiers reporting cold air round windows, across shopfronts below residential blocks, window and door perimeters on blocks and communal entrances and stairwells. Most enquiries from Cullivoe start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places such as Cullivoe, buildings managed by landlords and associations are often small groups of flats, sheltered housing and halls. Exposed walls take Scottish weather hard, and frame mastic shows it first.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Planned mastic for Cullivoe portfolios
Cullivoe is within about 1 mile of the coast. On buildings near the shore, the side facing the weather usually needs its mastic renewed first, so it’s worth inspecting those sides more often. The east of Scotland, where Cullivoe is, gets less rain than the west. External mastic still needs a dry joint and the right temperature, and winter mornings can be frosty. Block programmes are built with that in mind
Owners near Cullivoe can renew frame and external mastic block by block on one programme.
Cullivoe is in the Shetland Islands. We cover Cullivoe, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 63 places in the Shetland Islands, large and small.
Postcode districts covered here: ZE2 for mastic joints. Main routes into Cullivoe include the B9083, useful when we plan access and materials. We also cover Clivocast (4 miles south-east), Baltasound (6 miles north-east), Camb (7 miles south), Mid Yell (8 miles south) and Haroldswick (9 miles north-east). Where a site is remote or on an island, we plan travel and materials carefully.

Common questions from Cullivoe clients
Can one quote cover a number of our buildings near Cullivoe?
Yes, we quote for single buildings and for programmes across several blocks. We can phase the programme to suit your budgets and notice periods.
Is Cullivoe inside the area you cover, given it’s on an island?
Yes. Islands are part of our area, Cullivoe included. Island work is planned around ferry crossings and the weather, so photos and a full list before we travel are essential.
Do you check for asbestos in old sealant?
Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
Which sealant will you use?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can you send RAMS and CSCS details before starting?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Do you guarantee the mastic work?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
Diagnose, treat, sign off
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes a day or two for a single block, longer for an estate programme, and our waste is bagged and taken away as we go. For work around Cullivoe, we aim for one trip, which is why we ask for photographs and a full list first. External joints need a dry spell as well.
- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Getting the site ready
- Explain the parking and delivery arrangements
- Tell us which areas need to stay in use
- Make sure the joints can be reached

Advice
Places near Cullivoe
What else we do in Cullivoe
Different surfaces, different methods
Commercial and mixed-use buildings
Landlords with commercial portfolios have shopfronts, office entrances and external joints to look after. A planned programme suits multi-building portfolios.
External movement joints
Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.
Signs you need mastic sealing in Cullivoe
Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. We will tell you if the joint edges need repairing before resealing.
Most enquiries start with something like this:
- A mix of products and colours from past repairs
- Worn sealant at communal door frames
- Leaks at window and door perimeters
- Mastic failing across several blocks on an estate
Trustees of buildings like St Olaf's Church can bring frame and external mastic into a planned maintenance list.
Questions to ask before you book
- Are they CHAS accredited or on Constructionline?
- Whether primer will be used where the manufacturer specifies it
- Their approach to joint depth and backing
- Can the work be phased to keep areas open?
Leave it or put it right?
A bead run over old mastic can look like a repair. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. In Scotland, wind-driven rain finds a failed joint quickly, so it’s worth renewing joints around Cullivoe before they leak.
We don’t publish prices, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.
