About our fire stopping in Cornhill

It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance. Most enquiries involve openings found when ceilings come down for a refit and improvised or mixed-product fire seals, across pipe penetrations, cable penetrations and joints between fire-resisting walls and floors. Whoever orders the work in Cornhill, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In Scotland’s cities, university, hospital and office estates see services added year after year, and new cabling and pipework through compartment walls is a common reason fire stopping gets breached. New openings are closed with the specified fire-rated product, following its test evidence.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Owners, agents and contractors

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.

When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Questions about Cornhill

Can you work at a site such as Kittybrewster Shopping Centre, by Cornhill?

Yes. We cover Cornhill and the area around it, including industrial estates, business parks and retail parks such as Kittybrewster Shopping Centre. A few photos and the unit address let us price the work.

Will you work in a care home in Cornhill without moving residents out?

Yes. Care settings are planned area by area, at times agreed with the home. Noise and disruption are kept to a minimum.

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Can one quote cover more than one building?

Yes. A group of buildings can go on one quote, with one point of contact.

Do you have third-party installer accreditation for fire stopping?

No, and we won’t imply otherwise. Some clients require third-party installer schemes even though the law doesn’t. Where it isn’t required, we install the specified sealant to the maker’s details.

Is any job too small?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Is your workmanship covered by a guarantee?

Yes. Workmanship is guaranteed for 12 months.

Honest limits

Honesty saves time and money. New sealant won’t cure:

  • Gaps in walls that were never built as compartment walls
  • Fire doors, dampers or other fire safety equipment
  • Designing or specifying fire stopping, which sits with the designer or fire engineer

If in doubt, speak to us on 01277 525 020 or email the details over and we will say what we think before you book.

What we seal

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

What the job involves on each surface

Masonry and concrete

Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest so we know it sits within the tested range.

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We follow your schedule area by area, and note anything we find that isn’t on it.

Maintenance after handover

To get the most from the new sealant:

  • Agree the fire-stopping specification before services go in
  • Report damaged or disturbed seals as soon as they’re spotted
  • File the specified details where the next contractor can find them
  • Put resealing into every M&E and fit-out package

Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail.

The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open.

Fire stopping in Cornhill: the local picture

The area within 2 miles of Cornhill holds plenty of hotels. In hotels, bedroom and corridor walls are typically fire-resisting, so services added in a refit need sealing with the specified product. 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 products tested for that end use. Our part is installing the specified fire-rated sealant to its tested detail.

For a hotel such as Northern Hotel, 0.7 miles east of Cornhill, penetration seals are worth checking after any refit or services upgrade. At a healthcare site like Royal Cornhill Hospital, 0.7 miles south-east of Cornhill, new services through compartment walls are a constant, and each needs the specified seal. For a unit at a site such as Kittybrewster Shopping Centre, which lies east of Cornhill, any new service through a fire-resisting wall should be sealed to the tested detail.

How the quote is worked out

Before we quote, we look at:

  • Access and working height
  • Distance, for remote addresses
  • The total length or number of joints
  • Specialist products, such as fire-rated or hygienic sealants

A quote for service penetrations depends on how many there are, their condition and the access. Ask us for a fixed quote.

Before you send an enquiry

A good diagnosis starts with the right details. Let us know:

  • The site address and postcode
  • Specification clauses that apply
  • Photos of the joints, close up and from further back
  • Asbestos survey details if the building is older

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

How a job runs

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes a single visit for a short list of penetrations, or a phased programme for a whole building, and our waste is bagged and taken away as we go. University, hospital and office estates in Scotland’s cities have their own permits, inductions and sign-in rules. Tell us the rules and we’ll work to them.

  1. The specification and schedule come first, so we know which details apply.
  2. Access, permits and the order of areas are agreed with the site team.
  3. We compare every service penetration with its tested detail before sealing.
  4. Foam, ordinary sealant and debris come out first.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

What we need from you

  • For older buildings, check the asbestos register before work
  • Let us know about inductions and permits
  • Share your working hours and any access restrictions
