Fire stopping in Lamport

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

Fire stopping for commercial buildings in Lamport

We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on buildings around Lamport. Site teams most often ask us about expanding foam used as fire stopping and fire sealant pulled out of the opening, across small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and linear gaps at wall heads. For commercial sealant work in Lamport, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Smaller places such as Lamport still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

Work we carry out in Buckinghamshire comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or email a schedule or drawings and we will arrange a return visit.

What we can’t put right

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

  • Fire risk assessments, a job for a competent assessor
  • Writing the fire-stopping specification
  • Walls or floors that aren’t fire-resisting to begin with

Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

Joints and surfaces we work on

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

What affects the price in Lamport

A fixed quote reflects the actual work. It allows for:

  • Distance, for remote addresses
  • Phasing around occupants
  • Removal of failed or old sealant
  • Site requirements such as inductions and permits

Pricing service penetrations depends on quantities, condition and access, and any specification that applies. Call for a quote.

Sending details for a quote

We can often quote from photos and a few details. It helps to include:

  • Approximate linear metres or a joint schedule
  • The postcode of the building
  • Access details, including height
  • Any specification or named product

Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. If you have questions first, call the office on 01277 525 020 or email us.

Fire stopping around Lamport: what changes locally

Lamport lies roughly 53 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Either way, we install the specified product to its tested detail.

Older community buildings such as Parish Church of St Mary that have been rewired or given new heating can have service gaps through walls worth checking against the specification. Where a unit on an estate such as Moreton Road Industrial Estate, 1.4 miles south-east of Lamport, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.

Do you need fire stopping in Lamport?

Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint, and the wrong product can split as a result. Linear joint details set a width range and movement capability, and the seal has to sit within them.

If one of these sounds familiar, it’s time for a closer look:

  • Fire seals cut back for extra cables and never reinstated
  • Builders’ foam or ordinary silicone in compartment walls
  • Openings found when ceilings come down for a refit
  • Unsealed joints where partitions meet the slab

Wherever services are added at a hospital such as Buckingham Community Hospital (1.9 miles south of Lamport) the compartment line has to be made good with the specified product.

What your quote should include

  • How long is the guarantee, and what does it include?
  • How the joint faces will be prepared and primed
  • Who will actually carry out the work
  • Whether old or failed sealant will be cut out, not overlaid

Our contractor checklist

Our process

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself 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. Jobs in and around smaller places like Lamport are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Preparing the site

  • Send any specification or drawings in advance
  • Point out any areas we must not close
  • Send your site hours and access windows

Your questions answered

Can work in a care setting near Lamport go ahead while residents are there?

Yes, with the manager deciding the order and timing of rooms. Tell us about any infection-control or safeguarding requirements and we will work to them.

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Lamport?

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Do you need to see the site first?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

What do you charge?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.

Are you fully insured?

Yes. We’re fully insured, and the certificate can go with your quote.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Owners, agents and contractors

We work for building owners and managing agents on everything from one building to a spread of sites around Lamport. One quote can cover more than one site, which keeps the paperwork simple.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Lamport can sit alongside others in a wider programme.

Site staff or a sealant specialist?

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

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.
