Common questions from Stonebridge Green clients

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

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Can you seal penetrations in a hotel in Stonebridge Green after a refit?

Yes. We install fire-rated and intumescent sealant where it is specified. We match the product to the wall or floor and the services, and say if something other than sealant is needed.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, with one point of contact.

Does weather matter for sealant work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

How do I request a quote?

The quote form is the simplest route, though you can also call 01277 525 020 or email the details over. Include photographs or drawings if you have them.

Can you work while the building is occupied?

Typically, yes. Phased work can be planned so areas stay in use.

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.

About our fire stopping in Stonebridge Green

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate, and we won’t pretend otherwise. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. The enquiries we see most involve fire-rated sealant that has cracked or shrunk back and hidden openings found during inspections, on joints between fire-resisting walls and floors, cable penetrations and linear gaps at wall heads. For commercial sealant work in Stonebridge Green, you deal with one contact from quote to sign-off, whether it’s one building or several.

Around smaller places like Stonebridge Green, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

On site: what to expect

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and our waste is bagged and taken away as we go. For work around Stonebridge Green, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  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.

Getting the site ready

  • Move anything stored against the joints
  • Explain the parking and delivery arrangements
  • Have the specification and drawings to hand

What sealant work can’t fix

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Plastic pipes whose detail calls for a collar or wrap
  • Fire doors, dampers or other fire safety equipment
  • Writing the fire-stopping specification

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

Joints and surfaces we work on

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

What sets the cost

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • The site’s rules and procedures
  • Travel to remote or island sites
  • Access and working height
  • Specialist products, such as fire-rated or hygienic sealants

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Before you send an enquiry

Whether it’s one area or a whole building, these details speed things up:

  • Where the site is, with the postcode
  • Photos of the joints, close up and from further back
  • What the building is and how it’s used
  • Any dates the work must fit around

Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to phone 01277 525 020 or email us.

After the work

Problems stay small when the joints are checked regularly. Specifically:

  • Flag new cables with no seal around them
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Look above ceilings when tiles are lifted for other jobs
  • Leave fire sealant to cure fully before covering it

Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted, so check the product data first.

A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.

Should maintenance staff do it?

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Signs you need fire stopping in Stonebridge Green

Some service penetrations were never sealed at all, often hidden above suspended ceilings or behind boxing. Inspections, refurbishments and ceiling access usually bring them to light.

What tends to prompt an enquiry:

  • Unsealed penetrations discovered above suspended ceilings
  • Unsealed joints where partitions meet the slab
  • Seals disturbed by maintenance and left open
  • Builders’ foam or ordinary silicone in compartment walls

Schools such as Egerton Church of England 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

  • Their approach to joint depth and backing
  • Will failed sealant be removed rather than covered?
  • Are they CHAS accredited or on Constructionline?
  • What the guarantee covers, and for how long

Questions to ask before you appoint anyone

Compartment walls and floors in Stonebridge Green

Stonebridge Green has a number of hotels close by, all within 2 miles. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product. For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. We install whatever has been specified, to the product’s tested detail.

Older community buildings such as Church of St James that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
