Construction mastic for businesses in Clate

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

When it isn’t the sealant

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Frames fitted out of tolerance
  • Joint design decisions that belong to the architect or engineer
  • Defective windows, doors or glazing units (the supplier or installer’s job)

If in doubt, ring 01277 525 020 or email us and we’ll say what we think.

Joints and surfaces we work on

  • Floor and skirting junctions
  • Cladding and panel joints
  • Sanitary and kitchen joints
  • Internal decorators’ caulk
  • Brick and block movement joints
  • Window and door perimeters

Construction mastic in Clate

Buyers, tenants and clients notice sealant lines long before they notice the structure. Untidy or missed joints are among the commonest snag items. Our aim is joints that pass at the first inspection, whatever the size of the scheme. Site teams most often ask us about frame perimeters left unsealed or poorly sealed and failed sealant in an existing building being refurbished, on sanitary and kitchen joints, cladding and panel joints and internal decorators’ caulk. Searching for sealant specialists in Clate? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Clate that means watching the forecast. A little flexibility in the programme lets external joints go in on suitable days.

Work we carry out in the Shetland Islands comes with a 12-month guarantee. Should something we installed fail, call 01277 525 020 or send photos by email and we’ll come back to it.

Questions we’re asked in Clate

Can the mastic package for our job in Clate follow the site programme?

Yes. The mastic is planned around your key stages. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Our building in Clate is near the coast: does that change the sealant?

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.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Do you offer coloured sealant?

That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

Can you fit around our working hours?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day.

Work for main contractors and building owners

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’ll confirm with the quote.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Clate can form part of a wider programme.

When to call us in Clate

Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We use what’s specified, and any substitute goes to you for acceptance.

Clients typically get in touch after noticing something like this:

  • Old sealant on a refurbishment that needs stripping before new work
  • Internal caulk splitting as the building dries out
  • Window and door perimeters that won’t pass inspection
  • A long mastic snag list close to completion

Window perimeters and facade joints around Clate need correct width, depth and backing rod as much as a neat finish.

Comparing quotes

  • Whether primer will be used where the manufacturer specifies it
  • The terms of the workmanship guarantee
  • How they handle RAMS and site documents
  • How they’ll work around occupants

How to choose a sealant contractor

Different surfaces, different methods

External facade and movement joints

Many facade substrates need a primer before sealing. Primer goes on where the sealant maker calls for it, and seal only with a dry joint inside the product’s temperature range.

Bathrooms, en suites and washrooms

Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Joints are cleaned, sealed and tooled neatly.

Cost factors for mastic packages

A fixed quote reflects the actual work. It takes account of:

  • How accessible the joints are
  • Specialist products, such as fire-rated or hygienic sealants
  • How much existing material needs removing
  • Backing rod, priming and other preparation

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Before you send an enquiry

Whether it’s one area or a whole building, these details speed things up:

  • Rough lengths or quantities, or drawings if you have them
  • Access details, including height
  • Photos of the joints, close up and from further back
  • The type of building and who uses it

To get a fixed quote, phone 01277 525 020 or use the quote form, telling us the site location and the nature of the job. Our quote form is another easy route.

Diagnose, treat, sign off

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building near Clate, directions, keys and a contact on the day are worth sorting early. We’ll confirm the plan with the fixed quote.

  1. Drawings, the sealant specification and your programme come to us for pricing.
  2. We return a fixed quote that ties the mastic package to your programme.
  3. Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
  4. Work follows the programme, area by area, as rooms and elevations become ready.
  5. Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
  6. We close out snagging and hand over with a 12-month guarantee.

Getting the site ready

  • Send any specification or drawings in advance
  • Let building users know which areas are affected
  • Tell us your opening times and when work is allowed

Getting a fixed quote

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, speak to us on 01277 525 020 or send photos by email.

Contractors’ notes for Clate

Clate 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, and the sealant, primer and backing need choosing with that in mind. In Clate, as across Scotland, building warrants are issued by the local authority verifier under the Scottish regulations. Our job is to seal to that specification.

On any site in or around Clate, the mastic follows the specification and the programme.

Clate is about 13 miles north of Lerwick, in the Shetland Islands. Clate sits inside our coverage and the rest of the Shetland Islands, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. 63 places across the Shetland Islands fall within our area, Clate among them.

Commercial sites across ZE2 are covered for mastic packages. For a building on Rocky Road and Harlsdale or nearby, send details and we will quote for mastic packages. Nearby places we also cover include Sandwick (1 mile north), Symbister (1 mile north), Hamister (1 mile north), Huxter (1 mile east) and Tripwell (2 miles north-east) for mastic packages. Nearby towns on our patch include Lerwick (13 miles south), Sound (14 miles south) and Brae (12 miles west). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so give the site location in your enquiry.
