Need fire stopping in Colinton Mains?

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

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Approving the work on behalf of building control
  • Gaps in walls that were never built as compartment walls

Not sure which it is? You can call 01277 525 020 or email us and we will tell you honestly before you book.

What we seal

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

Fire stopping for commercial buildings in Colinton Mains

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate, and we won’t pretend otherwise. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. If you have old intumescent sealant that has split away and unsealed joints where partitions meet the slab, we can help. Whoever orders the work in Colinton Mains, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

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.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Looking after the joints

Keep the joints in good shape with a few simple steps:

  • Get seals inspected before ceilings and boxing close
  • Agree the fire-stopping specification before services go in
  • Record which product was used where
  • Don’t let anyone top up a fire seal with the wrong product

Keep the product data and installation details with the building’s fire safety information. Anyone resealing later needs to know which product and detail were used.

On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.

Why it’s worth doing now in Colinton Mains

The longer openings stay, the more there tend to be: each new service adds to the list. Keeping on top of it after each round of works keeps the job small and avoids a much larger catch-up later. In Colinton Mains, as across Scotland, rain finds any gap, so a split or hardened joint lets water into the wall. Renewing them early protects the fabric.

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

Why appoint us

  • One number for every site we cover
  • Fully insured
  • Failed material removed, not covered up
  • CHAS accredited

Cost factors for service penetrations

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • Working within restricted access windows
  • Induction, permit and paperwork requirements
  • The total length or number of joints
  • Removal of failed or old sealant

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

What we need to price the job

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • Drawings or a marked-up plan, if available
  • Clear photographs of the problem areas
  • Whether the building will be occupied during the work
  • Specification clauses that apply

To get a fixed quote, give us a call on 01277 525 020 or email us. You can also send details through our quote form.

Diagnose, treat, sign off

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. City jobs in Colinton Mains usually need parking and loading planned. Shared closes, stairs and the property factor may need to be part of the plan.

  1. First we go through the drawings, schedule or specification for the seals.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. We fit the backing the detail asks for, to the stated depth.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Preparing the site

  • Send your site hours and access windows
  • Have the specification and drawings to hand
  • Warn occupants and staff about the work

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Fire stopping in Colinton Mains: the local picture

Scottish guidance (non-domestic Technical Handbook, clause 2.1.14) asks that penetrations match at least the fire resistance period of the element they pass through, with products tested for that end use. Our part is installing the specified fire-rated sealant to its tested detail. Six care or nursing homes sit less than 2 miles from Colinton Mains. Where new services have gone through compartment walls in a care setting, the gaps need the specified product.

For a site team at a college like Edinburgh College - Sighthill Campus (2.6 miles north-west of Colinton Mains), fire-rated sealing is best scheduled after the summer works. Hospital estates such as Royal Edinburgh Hospital, 1.3 miles north of Colinton Mains, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. At a university such as Edinburgh Napier University, 1.4 miles north-west of Colinton Mains, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

Common questions from Colinton Mains clients

Is a hospital such as Royal Edinburgh Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Will you plan work around the academic year at somewhere like Edinburgh Napier University?

Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

How do I request a quote?

The quote form is the simplest route, though you can also call the office on 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.

Is BS 476 being phased out?

For buildings in England, Approved Document B removes BS 476 references from 2 September 2029. Products are then judged on BS EN 13501-2 classifications, subject to transitional arrangements. In Scotland, the Technical Handbook sets its own guidance, including clause 2.1.14 on service penetrations.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

What do BS EN 1366-3 and BS EN 13501-2 mean?

Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Results are classified under BS EN 13501-2 as E for integrity and I for insulation, with a time such as EI 60 or EI 120. The rating applies to the product as tested.
