Fire-rated sealing for Little London buildings

Fire stopping of openings and penetrations in England falls under Approved Document B. 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. At about 61 miles from central London, Little London is within reach of the capital. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.

Large healthcare estates like Andover Hospital (Grounds), 2.7 miles to the south-west of Little London, change their services often, so penetration seals are worth checking after M&E work. Colleges such as Andover College (to the south-west of Little London) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

Little London is about 3 miles north-east of Andover, in Hampshire. Looking for fire stopping in Little London? We can help. Little London is one of 723 places in Hampshire on our list for service penetrations. Our Southampton page has more on work in that area.

How we handle fire stopping in Little London

Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it. With no specification in place, the first step sits with your designer or fire engineer, not with us. Most enquiries involve unsealed penetrations discovered above suspended ceilings and improvised or mixed-product fire seals, across cable penetrations, small duct penetrations where the tested detail allows and linear gaps at wall heads. A specialist sealant contractor works differently from a general builder: on jobs in Little London, preparation and product choice get the time they need.

Smaller places such as Little London 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.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Diagnose, treat, sign off

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Jobs in and around smaller places like Little London are normally planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  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. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out first.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

Getting the site ready

  • Flag any permit to work we’ll need
  • Send your site hours and access windows
  • Arrange parking or a loading space

Building owners, agents and FMs in Little London

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

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, plus a 12-month guarantee.

General trades versus a specialist

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

FAQs: Little London

Can you work at a site such as Glenmore Trade Park, by Little London?

Yes. Estates, retail parks and business parks around Little London, Glenmore Trade Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

What does the BS 476 change mean for fire-rated sealant in Little London?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

What hours do you work?

We’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Do you work in Little London?

Yes. We cover Little London, and you can give us a call on 01277 525 020 or use the quote form to get started.

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 confirm what’s available for the specified product when we quote.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.

Common problems we fix in Little London

Physical damage is another reason seals stop doing their job. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped, and the repair is often skipped.

Any of the following is a good reason to get the joints checked over:

  • Open linear gaps along the top of fire-resisting walls
  • Old intumescent sealant that has split away
  • Fire seals cut back for extra cables and never reinstated
  • Openings left by services added after handover

Schools such as Smannell and Enham Church of England (Aided) Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

What to look for in a quote

  • Health and safety accreditation such as CHAS
  • The named product and why it was chosen

Cost factors for service penetrations

We price every job individually. The main factors are:

  • The size and state of each joint
  • Access and working height
  • Phasing around occupants
  • Site requirements such as inductions and permits

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

What to include in your enquiry

Whether it’s one area or a whole building, the same details help:

  • Approximate linear metres or a joint schedule
  • Asbestos survey details if the building is older
  • Specification clauses that apply
  • How the joints are reached, and at what height

Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. For a chat about it beforehand, phone 01277 525 020 or use the quote form.

What sealant work can’t fix

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Plastic pipes whose detail calls for a collar or wrap
  • Fire risk assessments, a job for a competent assessor
  • Designing or specifying fire stopping, which sits with the designer or fire engineer

If you’re not sure, just call 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.
