Fire stopping for Jacobs Well sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Quoting for work in Jacobs Well

Your fixed quote is built from the real scope. It takes account of:

  • Specialist products, such as fire-rated or hygienic sealants
  • Whether the work must be split into stages
  • Distance, for remote addresses
  • Backing rod, priming and other preparation

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

What to include in your enquiry

The more we know, the firmer the quote. When you get in touch, include:

  • Your programme or deadline
  • Whether the building will be occupied during the work
  • Approximate linear metres or a joint schedule
  • How the joints are reached, and at what height

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. To get it moving, speak to us on 01277 525 020 or send photos by email.

How we handle fire stopping in Jacobs Well

On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, speak to us on 01277 525 020 or use the quote form with the schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. If you are dealing with expanding foam used as fire stopping and fire seals cut back for extra cables and never reinstated, we can help, whatever the surface. One point of contact handles commercial sealant work in Jacobs Well from the first photographs to the final walk-round, whether it’s one building or several.

Barn and farm-building conversions near places like Jacobs Well 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.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Honest limits

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:

  • Large openings beyond what any sealant detail covers
  • Writing the fire-stopping specification
  • Construction that lacks the fire resistance the seal relies on

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

What we seal

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

Why it’s worth doing now in Jacobs Well

An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. The specified fire seal closes the gap for all of these and the building feels the difference. One visit to deal with every failing joint makes more sense than several trips to a place like Jacobs Well. Photos of every joint help us quote for the whole job.

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’ll put a fixed figure on it.

Why us?

  • Fully insured
  • A fixed quote before work starts
  • Constructionline member for supplier checks
  • 12 months’ guarantee on every job

Common questions from Jacobs Well clients

Do you take on work at healthcare sites like Mount Alvernia Hospital?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can work at a site such as University of Surrey fit around teaching?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

What will the job cost?

There isn’t a price list, because every site is different. With photos or drawings, we can give you a fixed quote.

Can you work to our specification?

Yes. Send it with your enquiry, and we will price the work to it.

Are you fully insured?

Yes. We’re fully insured, including public liability cover.

Does weather matter for sealant work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

How do you deal with asbestos in old sealant?

The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Keeping the joints sound

Regular inspection catches problems early. Specifically:

  • Have penetrations checked while they can still be seen
  • Ask which product is in place before decorating
  • Treat an open penetration as a priority repair
  • Brief every trade that openings they make must be sealed

Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.

Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.

How the job changes by surface

Cables and cable bundles

Single cables and small bundles are often within a fire-rated sealant’s tested detail. Bundle size, cable type and the space between cables all matter and we work within those limits.

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We follow your schedule area by area, and note anything we find that isn’t on it.

Diagnose, treat, sign off

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For work around Jacobs Well, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Preparing the site

  • Share your working hours and any access restrictions
  • Agree which areas must stay open
  • Tell staff and tenants when we will be in

Penetration seals near Jacobs Well

Jacobs Well lies roughly 26 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. The area within 2 miles of Jacobs Well holds a number of hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.

For a building such as St Peter's Church, new heating or data runs are the usual reason penetrations need sealing. For a unit at a site such as Ladymead Retail Park, which lies south of Jacobs Well, any new service through a fire-resisting wall should be sealed to the tested detail. On a hospital site such as Mount Alvernia Hospital (2.2 miles south of Jacobs Well), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
