Construction mastic for businesses in Boleside

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Construction mastic in Boleside, done properly

We work to the specification and the programme rather than whatever product is to hand. Where the specification names a product, we use it, and if an alternative is proposed, it goes to you for acceptance first. Joint widths, backing, primers and tooling follow the manufacturer’s guidance, so the joints perform as the designer intended. We work on floor and skirting junctions, internal decorators’ caulk and brick and block movement joints, and what we’re called in for most is mastic snags holding up handover and existing joints on a refurb that need cutting out and resealing. Whoever orders the work in Boleside, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

Sites near smaller places like Boleside can mean longer travel, so the mastic is planned with as few trips as the job allows. Send drawings, photographs and the programme so everything needed arrives on the first day.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

What happens if it’s left?

On a refurbishment, there’s a choice between resealing existing frames and replacing them. If the frame is in good order, cutting out and resealing the perimeter can be all it needs and that’s a far smaller job. We’ll say so if a frame itself is the problem. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like Boleside, a repair visit takes planning, so it’s better to act early.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Building owners, agents and FMs in Boleside

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Boleside can sit alongside others in a wider programme across the Scottish Borders.

From enquiry to sign-off

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before the next one starts. Where we can, we combine work around Boleside with other jobs nearby. Tell us how flexible your dates are.

  1. We walk the site or review drawings to understand the package.
  2. A fixed quote sets out scope, products and phasing.
  3. Paperwork is agreed and applicators are inducted on site.
  4. Sealing follows the programme as areas are released.
  5. Problems we find, such as oversized gaps, are raised right away.
  6. The package is closed out, snags cleared and backed by our 12-month guarantee.

Preparing the site

  • Make sure the joints can be reached
  • Warn occupants and staff about the work

Advice

New build and refits around Boleside

The east of Scotland, where Boleside is, gets less rain than the west. Frost and condensation on frames and panels can still hold up external mastic on winter mornings. External mastic is planned with the site manager for workable conditions. Scotland has its own building regulations, and in Boleside warrants come from the local authority verifier. We seal to the specification that sits behind the warrant.

For a contractor at a hotel such as Kingsknowes Hotel, which lies north-east of Boleside, the mastic often has to be finished before a reopening date. On a healthcare site such as Borders General Hospital, 2.2 miles to the east of Boleside, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Further education sites such as Borders College - Galashiels Campus, 1.2 miles to the north-east of Boleside, are extended and refurbished from time to time, with mastic often programmed into the summer break.

Boleside is about 2 miles south of Galashiels, in the Scottish Borders. Any commercial site in Boleside is covered, whether it’s a single job or part of a planned programme. Our the Scottish Borders coverage takes in 91 places, from busy centres to rural villages. Edinburgh is covered too, some 29 miles away.

Postcode districts covered here: TD1 for mastic packages. If your building is just outside Boleside, we cover Tweedbank (2 miles north-east), Galashiels (2 miles north), Langlee (2 miles north-east), Darnick (2 miles east) and Melrose (3 miles east). Bigger towns within reach include Hawick (12 miles south), Kelso (14 miles east), Selkirk (3 miles south-west), Jedburgh (13 miles south-east), Wilton (11 miles south) and Innerleithen (10 miles west).

What the job involves on each surface

Fire-rated sealant where specified

Not every penetration suits a sealant. Other products are used for some services and gaps so we’ll flag where the detail needs something different. Record requirements are agreed with the quote.

Internal decorators’ caulk

Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s for gaps that stay still and get painted while moving joints need a flexible sealant.

Quoting for work in Boleside

To price the job, we consider:

  • Backing rod, priming and other preparation
  • Distance, for remote addresses
  • Access and working height
  • Whether old sealant has to be cut out first

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

What we need to price the job

To price the job accurately, we need to understand the site. Send us:

  • What the building is and how it’s used
  • Whether an asbestos survey exists
  • Access details, including height
  • Specification clauses that apply

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, ring 01277 525 020 or email a schedule or drawings.

Should maintenance staff do it?

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
