Fire stopping in Little Horwood

Facilities managers in Little Horwood often find open service penetrations when ceilings come down for other work. If a specification already covers those walls and floors, we can reseal to it using the product and detail it sets out. With no specification in place, the first step sits with your designer or fire engineer, not with us. If you are dealing with open linear gaps along the top of fire-resisting walls and seals disturbed by maintenance and left open, we can put it right, whatever the surface. A single leaking joint is often how a building in Little Horwood first comes to us: we look at the rest while we’re there and tell you what we find.

For a smaller site near Little Horwood, we plan to do all the penetrations in one go, with the specification and photographs sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

What affects the price in Little Horwood

Quotes vary with the job. It mainly depends on:

  • Whether old sealant has to be cut out first
  • Site requirements such as inductions and permits
  • Distance, for remote addresses
  • The size and state of each joint

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

What we need to price the job

The more we know, the firmer the quote. Helpful details to send:

  • The site address and postcode
  • Photos of the joints, close up and from further back
  • The type of building and who uses it
  • How the joints are reached, and at what height

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or email us.

When to call us in Little Horwood

Openings in fire-resisting walls usually appear when services are added or changed. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser can leave the hole behind. Over a few years of fit-outs, a wall can collect a lot of these.

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

  • Penetration schedules that need working through
  • Fire sealant pulled out of the opening
  • Unsealed joints where partitions meet the slab
  • Openings left by services added after handover

Offices at parks like Greenway Business Park, 1.5 miles west of Little Horwood, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.

Comparing quotes

  • Their public liability cover
  • Whether their applicators hold CSCS cards
  • Which product they’ll use, and why it suits the joint
  • Their approach to joint depth and backing

What we can’t put right

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Issuing fire ratings or certificates for seals
  • Large openings beyond what any sealant detail covers

If in doubt, give us a call on 01277 525 020 or email drawings and photos and we will say what we think before you book.

What we seal

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

Where services cross fire walls in Little Horwood

In England, Approved Document B covers fire stopping of openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Little Horwood lies roughly 46 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.

In a building such as Church of St Nicholas, any service penetration through a fire-resisting wall should be sealed to the specified detail. Wherever services are added at a hospital such as Bletchley Community Hospital (4.7 miles north-east of Little Horwood) the compartment line has to be made good with the specified product.

Little Horwood is about 5 miles west of Bletchley, in Buckinghamshire.

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. 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: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Questions we’re asked in Little Horwood

Would you work within a site like Bletchley Community Hospital?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

Do you cover business parks and estates near Little Horwood, such as Greenway Business Park?

Yes. Our area takes in Little Horwood and its surroundings, with estates and business parks such as Greenway Business Park included. Photos and a short description are enough for a first look.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

What site paperwork can you supply?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Do you need to see the site first?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.

Will fire-rated sealant work on every penetration?

No. It depends on the tested detail for that wall or floor and service. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards, and we will tell you when that applies.

What will the job cost?

There isn’t a price list, because every site is different. With photos or drawings, we can give you a fixed quote.

On site: what to expect

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Smaller jobs around Little Horwood can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.

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

Getting the site ready

  • Tell us your opening times and when work is allowed
  • Arrange parking or a loading space
  • Confirm the product named in the specification
