Questions about Spring Park

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

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Is hospital work, at somewhere like Bethlem Royal Hospital, something you do?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

What hours do you work?

Give us your site hours and any access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Is colour matching possible?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.

How we handle fire stopping in Spring Park

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate and we’d rather say that up front. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. Most enquiries involve fire seals cut back for extra cables and never reinstated and openings left by services added after handover, on pipe penetrations, service gaps in risers and linear gaps at wall heads. For commercial sealant work in Spring Park, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

In a London area such as Spring Park, buildings are refitted often, and every new cable, pipe or duct through a fire-resisting wall or floor leaves a gap. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Compartment walls and floors in Spring Park

There are three care or nursing homes within about 2 miles of Spring Park. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail. London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements.

Wherever services are added at a hospital such as Bethlem Royal Hospital (to the north of Spring Park) the compartment line has to be made good with the specified product. Tenant changes at centres like The Mall (2.8 miles north-east of Spring Park) often mean new services through walls between units. Colleges such as Shaftesbury Nash College, 1.6 miles to the east of Spring Park, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

Spring Park is about 2 miles south of Beckenham, in Greater London. Across the CR0 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 764 places in Greater London, from busy centres to rural villages. There’s a separate page for London, roughly 9 miles from Spring Park.

On site: what to expect

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before the next one starts. In Spring Park, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.

  1. First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
  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. Mineral wool or other backing goes in wherever the detail asks.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Getting the site ready

  • Tell staff and tenants when we will be in
  • Tell us which areas need to stay in use
  • Confirm the product named in the specification

Related advice

When it isn’t the sealant

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Fire doors, dampers or other fire safety equipment
  • Gaps in walls that were never built as compartment walls
  • Writing the fire-stopping specification

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

Joints and surfaces we work on

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

For managing agents and facilities managers

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Spring Park. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Surface by surface

Drylining partitions

Plasterboard partitions are tested as a specific construction. The sealant detail has to be tested in that wall type, with the stated board layers first.

Linear joints

Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed, and we work within it.

Cost factors for service penetrations

A fixed quote reflects the actual work. It takes account of:

  • Site requirements such as inductions and permits
  • Travel to remote or island sites
  • Joint width, depth and condition
  • Access and working height

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 we will put a fixed figure on it.

Before you send an enquiry

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

  • What the building is and how it’s used
  • Whether an asbestos survey exists
  • The product your specification calls for
  • The postcode of the building

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Should maintenance staff do it?

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
