Fire stopping for commercial buildings in Lewiston

A fire-rated sealant is only one part of a tested system: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in, and raise it with you if it falls outside. If you have fire stopping installed outside its tested range and snag lists that include open service penetrations, we can put it right. Most enquiries from Lewiston start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Around smaller places such as Lewiston, compartment walls and floors tend to be in schools, hotels, care homes and community buildings. Those penetrations are closed with the product the specification names, built up as tested.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Diagnose, treat, sign off

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Where we can, we combine work around Lewiston with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.

  1. We read the specification, drawings or penetration schedule you send.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

What we need from you

  • Arrange parking or a loading space
  • Tell staff and tenants when we’ll be in
  • Agree which areas must stay open

Fire stopping around Lewiston: how the place shapes the job

In Scotland, clause 2.1.14 of the non-domestic Technical Handbook expects service penetrations to keep at least the fire resistance duration of the wall or floor, with proprietary products, intumescent ones included, tested for their end use. We install what’s specified, to the product’s tested detail. A 2-mile radius around Lewiston takes in several hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.

For a building such as Kilmore Parish Church of Scotland, new heating or data runs are the usual reason penetrations need sealing. Holiday works at schools like Glen Urquhart High School often leave service openings to seal before pupils return. For a hotel such as Benleva Hotel, which lies north-east of Lewiston, penetration seals are worth checking after any refit or services upgrade.

Lewiston is about 13 miles south-west of Inverness, in Highland. Commercial clients in Lewiston can call on us for service penetrations. Our Highland coverage takes in 256 places, large and small.

If you need fire stopping in IV63, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. If your site is on Dal of Borlum, Carn Glas and Carriers Croft or close by, we can quote for service penetrations. Nearby places we also cover include Drumnadrochit (1 mile north), Torness (4 miles east), Gorthleck (6 miles south), Dores (7 miles north-east) and Kiltarlity (8 miles north). Further afield, our area takes in Inverness (13 miles north-east), Merkinch (14 miles north-east), Hilton (13 miles north-east), Crown (14 miles north-east), Millburn (14 miles north-east) and Muir of Ord (13 miles north). Where a site is remote or on an island, travel and materials need planning ahead, so include the location in your enquiry.

Why act early in Lewiston

A seal that doesn’t match its tested detail gives false comfort. Correcting it means cutting it out and starting again with the specified product. Around smaller places like Lewiston, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Early resealing prevents it.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Your questions answered

Which Scottish guidance covers penetration seals in Lewiston?

The non-domestic Technical Handbook, clause 2.1.14, expects a penetration to keep at least the wall or floor’s fire resistance period, with proprietary products tested for the use they’re put to. We install what has been specified, to the manufacturer’s tested detail, while design and approval sit with the designer and the verifier.

Is Lewiston too far out for you?

Not at all. Lewiston is within our area. We work across every Scottish council area. We plan jobs in smaller places so return trips are kept to a minimum.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

Are you fully insured?

Yes. We are fully insured, including public liability cover.

Do you seal on top of existing sealant?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Is colour matching possible?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.

When something else is needed

Being straight saves everyone time. Fresh joints won’t solve:

  • Gaps in walls that were never built as compartment walls
  • Issuing fire ratings or certificates for seals
  • Openings that need collars, wraps, batts or boards rather than sealant

If in doubt, call the office on 01277 525 020 or send photos by email and we will say what we think before you book.

Surfaces we seal

  • Linear gaps at wall heads
  • Service gaps in risers
  • Joints between fire-resisting walls and floors
  • Cable penetrations
  • Small duct penetrations where the tested detail allows
  • Pipe penetrations

Should maintenance staff do it?

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.

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

How the quote is worked out

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

  • Whether the work must be split into stages
  • Site requirements such as inductions and permits
  • Travel to remote or island sites
  • Backing rod, priming and other preparation

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What we need to price the job

A good diagnosis starts with the right details. Tell us:

  • Where the site is, with the postcode
  • Photos of the joints, close up and from further back
  • Any dates the work must fit around
  • The asbestos register, for older buildings

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, give us a call on 01277 525 020 or use the quote form.
