Commercial clients in Old Warren

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.

CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Fire stopping in Old Warren, done properly

The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints and the results are classified to BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. Site teams most often ask us about unsealed joints where partitions meet the slab and service penetrations left open after M&E works, across service gaps in risers, joints between fire-resisting walls and floors and linear gaps at wall heads. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Old Warren, preparation and product choice get the time they need.

Barn and farm-building conversions near places like Old Warren often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

Our workmanship is guaranteed for 12 months, in Old Warren as everywhere else we work. If our installation lets you down in that time, we return and fix it.

FAQs: Old Warren

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

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Is Old Warren too small for you to travel to?

Not at all. Old Warren is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

How do I request a quote?

The quote form is the simplest route, though you can also give us a call on 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.

Can you quote from photos?

It depends on the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs normally get a visit.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

Can you fit around our working hours?

Give us your site hours and any access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

What affects the price in Old Warren

What shapes the price:

  • The total length or number of joints
  • The site’s rules and procedures
  • Backing rod, priming and other preparation
  • Phasing around occupants

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

What we need to price the job

For an accurate fixed quote, we need a clear picture of the site. Useful things to include:

  • Photos of the joints, close up and from further back
  • Asbestos survey details if the building is older
  • Specification clauses that apply
  • The type of building and who uses it

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to phone 01277 525 020 or send photos by email with what you know.

Aftercare for building managers

After handover, a little attention goes a long way:

  • File the specified details where the next contractor can find them
  • Don’t let anyone top up a fire seal with the wrong product
  • Include service cupboards in routine inspections
  • Ask the designer to confirm details early on refits

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted, and the data sheet says which.

The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there.

Compartments and services around Old Warren

At about 45 miles from central London, Old Warren is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. A 2-mile radius around Old Warren takes in several hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.

Halls and meeting rooms at places like The Parish Church of St.Saviours sometimes gain new services, and any compartment wall crossed needs the specified seal. Hotels such as The Broomsquire Hotel (to the south-west of Old Warren) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. On estates like Stacey Industrial Park, which lies south-west of Old Warren, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

Surface by surface

Small ducts

Ducts are only sealed with sealant where the detail allows it. Dampers and ductwork systems themselves are outside our work.

Masonry and concrete

Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening.

When something else is needed

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

  • Reviewing a building’s overall fire safety
  • Large openings beyond what any sealant detail covers
  • Designing or specifying fire stopping, which sits with the designer or fire engineer

Not sure which it is? You can ring 01277 525 020 or email the details over and we will tell you honestly before you book.

Where we work in Old Warren

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

From enquiry to sign-off

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 typically takes a single visit for a short list of penetrations, or a phased programme for a whole building, and we clear our waste as we work. Rural sites near Old Warren may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. First we go through the drawings, schedule or specification for the seals.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  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. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

What we need from you

  • Send asbestos survey details if the building is pre-2000
  • Tell staff and tenants when we will be in
  • Move anything stored against the joints
