What we’re called out for in Hamister
Three-sided adhesion is a frequent fault on new work. Bonded to the base of the joint and both sides, sealant can’t stretch evenly, so depth is controlled with backing rod or bond-breaker tape.
Look out for the following:
- Oversized or tapered gaps around new frames
- A mastic package split between trades with no clear owner
- Existing joints on a refurb that need cutting out and resealing
- Early adhesion failures on new external joints
Sites around Hamister get mastic sealed to the drawings and the programme, nothing improvised.

Construction mastic for commercial buildings in Hamister
Since 2005 we’ve worked alongside main contractors, developers and fit-out firms. We price from drawings and the specification, agree the sequence with the site team and seal as areas are released. To price a package in Hamister, send drawings and the specification through our quote form. 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 help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Hamister, that means joint design, primers and backing rod as standard.
For a site around Hamister, we plan the mastic in as few trips as the programme allows. Send drawings, photos and the programme so everything needed arrives on the first day.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Construction mastic around Hamister: what changes locally
Hamister lies within about 1 mile of the sea. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, and the sealant, primer and backing need choosing with that in mind. Hamister is on Scotland’s drier eastern side. Frost and condensation on frames and panels can still hold up external mastic on winter mornings. External dates keep a little give.
Window perimeters and facade joints around Hamister need correct width, depth and backing rod as much as a neat finish.
Hamister is in the Shetland Islands. Commercial clients in Hamister can call on us for mastic packages, as part of our coverage of the Shetland Islands. Across the Shetland Islands, 63 places are covered, including Hamister.
Business premises anywhere in ZE2 are within our area. We cover commercial and managed buildings on Norrendal and North Park and the roads nearby. Nearby places we also cover include Symbister (1 mile south), Tripwell (1 mile north-east), Sandwick (1 mile south), Clate (1 mile south) and Brough (1 mile north-east). Nearby towns on our patch include Lerwick (15 miles south), Sound (15 miles south) and Brae (12 miles west). Where a site is remote or on an island, we plan travel and materials carefully.

What the job involves on each surface
Bathrooms, en suites and washrooms
On multi-unit schemes, consistency matters across hundreds of bathrooms. One applicator team gives the same finish everywhere.
Kitchens and utility areas
Worktop upstands, sinks and splashbacks are sealed once the kitchen is fitted. A kitchen-suitable sealant is used.
Your questions answered
Can you work to our programme on a site in or near Hamister?
Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Can being near the sea in Hamister affect the sealant we need?
It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Does weather affect external mastic work?
Conditions have to suit the product before external work starts. Wet or cold joints cause adhesion problems, so we wait rather than redo work.
What do you charge?
That depends on the job: quantities, access, the product and any phasing. Call for a quote and we’ll price it properly.
Can you come in just for snagging?
Yes. Send the snag list or photos and we will price it, with the work timed to your handover date.
Do you need to see the site first?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
What joints do you seal on a new build?
External and internal frame perimeters, caulking where it’s specified, sanitary silicone, kitchen joints and snagging before handover. The scope follows your specification.
Quoting for work in Hamister
We price every job individually. The main factors are:
- Quantities, in metres or numbers
- Joint width, depth and condition
- Whether the work must be split into stages
- Site requirements such as inductions and permits
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.
What we need to price the job
Whether it’s one area or a whole building, the same details help:
- Clear photographs of the problem areas
- Whether an asbestos survey exists
- Specification clauses that apply
- Rough lengths or quantities, or drawings if you have them
Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, call 01277 525 020 or email us.

When to bring in a specialist
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
