About our fire stopping in Little Heath

No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and we say so if it doesn’t fit. If you’re dealing with expanding foam used as fire stopping and unsealed joints where partitions meet the slab, we can put it right. For commercial sealant work in Little Heath, you deal with one contact from quote to sign-off, whether it’s one building or several.

After a fit-out or new cabling in a London building, risers and ceiling voids are where open service gaps tend to be found. Fire-rated sealant goes in where it’s the specified item; where a collar, wrap or batt is called for instead, we flag it.

A 12-month guarantee applies to all our work. Should something we installed fail, speak to us on 01277 525 020 or send details through our quote form and we will come back to it.

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. 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.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Common questions from Little Heath clients

Do you cover business parks and estates near Little Heath, such as Grove Farm Retail Park?

Yes. We cover Little Heath and the area around it, including industrial estates, business parks and retail parks such as Grove Farm Retail Park. To start, just give us a call on 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Do you take on jobs in Little Heath where loading and access are tightly controlled?

Yes, most London buildings have access rules of some kind, and we plan around them. Share the building’s contractor rules and we will work to them. All of Greater London is inside the ULEZ, and our planning allows for it

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Is sealant suitable for all service openings?

No. It depends on the tested detail for that wall or floor and service. Collars, wraps, batts and boards exist for openings sealant doesn’t cover, and we will tell you when that applies.

Is any job too small?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Do you approve fire stopping for building control?

No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. We work to the specification and the manufacturer’s installation guidance, and any records you need can be confirmed with the quote.

What’s the quickest route to a quote?

You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or email the details over. Photos, drawings or a joint schedule help us quote quickly.

How a job runs

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself usually taking longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Planning a London job such as one in Little Heath starts with access. Give us the hours we can be on site and we’ll schedule to suit.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  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. Completed areas are checked with you, with the records agreed when we quoted.

Before we start on site

  • Warn occupants and staff about the work
  • Point out any areas we must not close
  • Make sure the joints can be reached

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

Surface by surface

Cables and cable bundles

New data and power cables are the most common breach we see. We reseal around them to the specified detail, and we tell you if the bundle exceeds what sealant covers.

Risers and ceiling voids

Service risers and the voids above ceilings are where openings collect. Access is often tight, so we agree it with you in advance, including keys, permits and any isolations.

Quoting for work in Little Heath

Before we quote, we look at:

  • Quantities, in metres or numbers
  • Removal of failed or old sealant
  • Access and working height
  • Distance, for remote addresses

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What we need to price the job

A few photos plus some basic facts will normally do. It helps to include:

  • Access details, including height
  • A wide shot and a close-up of the area
  • Specification clauses that apply
  • Any dates the work must fit around

Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. For a chat about it beforehand, ring 01277 525 020 or email a schedule or drawings.

Fire-rated sealing for Little Heath buildings

London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. We seal to the specification and the product’s tested detail, working within the building’s permits. A 2-mile radius around Little Heath takes in a number of hotels. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product.

For a school such as Grove Primary School, penetration sealing fits best at the end of the summer works. At a healthcare site like King George Hospital, 0.6 miles west of Little Heath, new services through compartment walls are a constant, and each needs the specified seal.

Little Heath is about 2 miles west of Romford, in Greater London. Little Heath sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 764 places in Greater London. Sites around London have their own page, about 11 miles away.

Owners, agents and contractors

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Do you need fire stopping in Little Heath?

When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are what we find most often.

Site and facilities staff are often the first to spot these:

  • Unsealed penetrations discovered above suspended ceilings
  • Snag lists that include open service penetrations
  • Seals disturbed by maintenance and left open
  • Head-of-wall gaps with no fire seal

Refits at places like Grove Farm Retail Park, 0.7 miles to the south of Little Heath, often reroute services through walls between units.

What your quote should include

  • How the joint faces will be prepared and primed

  • Proof of insurance
  • Which product they’ll use, and why it suits the joint
