Questions about Borgh

Does the sea air around Borgh change the choice of sealant?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Will you fit the mastic around our build programme in Borgh?

Yes. The mastic is planned around your key stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

What if there’s asbestos in the old mastic?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Can you fit around our programme?

We follow the trades through the building. Each plot, floor or elevation is sealed when it’s ready, and we’ll raise anything that holds the work up.

What do you charge?

There isn’t a price list, because every site is different. Send photos or drawings and we’ll price it at a fixed figure.

Does weather affect external mastic work?

Outside, the joint has to be dry and the temperature within the product’s limits. Damp, frost or condensation on frames can stop work.

How long does a job like this take?

The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.

About our construction mastic in Borgh

A typical mastic package covers more than window perimeters: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. Splitting those between trades often leaves gaps in responsibility, and one applicator team gives a consistent finish. If you are dealing with failed sealant in an existing building being refurbished and mastic snags holding up handover, we can put it right. A specialist sealant contractor works differently from a general builder: in Borgh, that means joint design, primers and backing rod as standard.

For a site around Borgh, we plan the mastic in as few trips as the programme allows. Clear drawings, a programme and photographs let us bring the right sealants, primers and backing rod first time.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

When to call us in Borgh

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 stick to the specified product, or put any alternative to you first.

Most enquiries start with something like this:

  • A long mastic snag list close to completion
  • Window and door perimeters that won’t pass inspection
  • Failed sealant in an existing building being refurbished
  • Oversized or tapered gaps around new frames

Hotel extensions and refits, at places such as Borve Country House Hotel, less than half a mile to the north-east of Borgh, usually run between busy periods, so the sealing is squeezed into short windows.

What your quote should include

  • Who will actually carry out the work
  • Will failed sealant be removed rather than covered?
  • Is the sealant right for the movement and the substrate?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Choosing a commercial sealant contractor

Contractors’ notes for Borgh

With the shore within about 1 mile, Borgh counts as a coastal location. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Projects in Borgh follow Scotland’s building regulations, with the local authority acting as verifier. We seal to the specification that sits behind the warrant.

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

Borgh (Gaelic: Borve) is in Na h-Eileanan Siar. Any commercial site in Borgh is covered. Our Na h-Eileanan Siar coverage takes in 87 places.

Among the streets we cover are Gearra Mor and Sraid na H-Eaglaise, and sites on any of them can send details for a fixed quote.

Looking after the joints

Cleaning and maintenance staff play a part too. Share these points with them:

  • Don’t schedule sealing before decorators and flooring are done
  • Plan external elevations with the weather in mind
  • Record the products used in the O&M file
  • Protect sealed areas from following trades

Any damage after we’ve finished should go on the snag list right away. Snags can be picked up in a planned close-out visit.

External joints sealed in poor weather are a common cause of early failure. Holding off until conditions suit avoids callbacks.

What we can’t put right

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:

  • Specifying the product where the designer hasn’t
  • Oversized gaps that need packing or adjustment by others
  • Damage to finishes by other trades after we have sealed

If in doubt, speak to us on 01277 525 020 or email drawings and photos and we will say what we think.

Surfaces we seal

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

Different surfaces, different methods

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.

External facade and movement joints

Movement joints in the facade are sealed with a product suited to the expected movement. Depth is controlled with backing rod so the bead bonds to two sides only.

Diagnose, treat, sign off

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Borgh, we aim for one trip, so photos, sizes and a full list matter. Outside work also needs a suitable weather window.

  1. We walk the site or review drawings to understand the package.
  2. You receive a fixed quote covering scope, products and sequence.
  3. Paperwork is agreed and applicators are inducted on site.
  4. We seal plot by plot or floor by floor in line with the programme.
  5. Problems we find, such as oversized gaps, are raised straight away.
  6. Final snagging is completed and the 12-month guarantee applies.

Getting the site ready

  • Flag any permit to work we’ll need
  • Move anything stored against the joints
  • Share your working hours and any access restrictions

Advice

When to bring in a specialist

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
