Fire stopping for Penton Hook sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Why act early in Penton Hook

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach. Older rural buildings around Penton Hook move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

  • One phone line for London, the South East and Scotland
  • Sealing commercial buildings since 2005
  • Constructionline member
  • Old sealant cut out, never sealed over

About our fire stopping in Penton Hook

On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we will confirm with the quote. We work on service gaps in risers, joints between fire-resisting walls and floors and pipe penetrations, and what we’re called in for most is service penetrations left open after M&E works and unsealed penetrations discovered above suspended ceilings. Facilities teams, main contractors and managing agents in Penton Hook tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Smaller places such as Penton Hook still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

A 12-month guarantee applies to all our work. If an installation problem shows up, speak to us on 01277 525 020 or email a schedule or drawings and we’ll arrange a return visit.

Where services cross fire walls in Penton Hook

Penton Hook has two care or nursing homes no more than 2 miles away. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail. In England, Approved Document B covers fire stopping of openings and penetrations. 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. Either way, we install the specified product to its tested detail.

Residences at universities like Royal Holloway University, 3.1 miles to the north-west of Penton Hook, have compartment walls that must be resealed whenever services change. On estates like Thorpe Industrial Estate, 1.4 miles west of Penton Hook, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal. Workshops and IT rooms at colleges like Brooklands College - Ashford Campus, 2.5 miles to the north-east of Penton Hook, are re-serviced often, leaving penetrations to seal.

Maintenance after handover

A few simple habits keep the new joints working:

  • Report damaged or disturbed seals as soon as they’re spotted
  • Keep general-purpose fillers away from compartment walls
  • Agree the fire-stopping specification before services go in
  • Ask which product is in place before decorating

Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Look for cracks, unsealed new cables and gaps that have been enlarged.

Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned.

Questions we are asked in Penton Hook

Is Penton Hook too small for you to travel to?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Does your area include sites such as Thorpe Industrial Estate, near Penton Hook?

Yes. Our area takes in Penton Hook and its surroundings, with estates and business parks such as Thorpe Industrial Estate included. Photos and a short description are enough for a first look.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

Which standards are fire seals tested to?

In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. EI 60 means integrity and insulation for 60 minutes in the tested arrangement; installing to the detail is what carries that across to site.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

From enquiry to sign-off

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area.

Advice

Cost factors for service penetrations

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • The site’s rules and procedures
  • Quantities, in metres or numbers
  • How much existing material needs removing
  • Whether the work must be split into stages

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.

What we need to price the job

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

  • The product your specification calls for
  • A wide shot and a close-up of the area
  • Whether the building will be occupied during the work
  • How the joints are reached, and at what height

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, ring 01277 525 020 or send details through our quote form.

When to bring in a specialist

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
