Fire stopping across Stroud

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

Common problems we fix in Stroud

Physical damage is another reason seals stop doing their job. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped.

It’s worth sending us details if you spot any of the following:

  • Unsealed openings around new pipes and cables
  • Hidden openings found during inspections
  • Seals disturbed by maintenance and left open
  • Expanding foam used as fire stopping

At a healthcare site like Petersfield Hospital, 1.3 miles east of Stroud, new services through compartment walls are a constant, and each needs the specified seal.

How to choose a sealant contractor

How we handle fire stopping in Stroud

On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, ring 01277 525 020 or use the quote form with the schedule or marked-up drawings and the specified product data. Tell us what records you need and we’ll confirm with the quote. Most enquiries involve fire stopping installed outside its tested range and expanding foam used as fire stopping, across small duct penetrations where the tested detail allows, pipe penetrations and service gaps in risers. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Stroud, preparation and product choice get the time they need.

For a smaller site near Stroud, we plan to do all the penetrations in one go, so send the specification and photographs first. Design and sign-off belong to the designer or building control; we install what’s specified.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Leave it or put it right?

Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. While the openings can be reached, sealing them is normally straightforward. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Around Stroud, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Why us?

  • Fully insured, including public liability cover
  • Our applicators hold CSCS cards
  • 12-month guarantee on workmanship
  • Fixed quotes based on photographs, drawings or a visit

Cost factors for service penetrations

We price every job individually. The things that drive the figure:

  • Quantities, in metres or numbers
  • The product specified
  • Backing rod, priming and other preparation
  • Induction, permit and paperwork requirements

A quote for service penetrations depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Sending details for a quote

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • Rough lengths or quantities, or drawings if you have them
  • What the building is and how it’s used
  • Whether an asbestos survey exists
  • Any dates the work must fit around

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

Building owners, agents and FMs in Stroud

Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules.

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.

Doing it in-house

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Questions about Stroud

Can you take on a job at a hospital such as Petersfield Hospital?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

How does the move away from BS 476 affect penetration seals in Stroud?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Does weather matter for sealant work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

What happens if old sealant might contain asbestos?

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

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Do you guarantee your work?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

From enquiry to sign-off

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Jobs in and around smaller places like Stroud are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. We read the specification, drawings or penetration schedule you send and ask about anything unclear.
  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. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Before we start on site

  • Send your site hours and access windows
  • Confirm the product named in the specification
  • Let us know about inductions and permits

Advice

Penetration seals near Stroud

The area within 2 miles of Stroud holds a number of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. In England, Approved Document B covers fire stopping of openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Either way, we install the specified product to its tested detail.

Halls and meeting rooms at places like Stroud Mission Church sometimes gain new services, and any compartment wall crossed needs the specified seal. Schools such as Langrish Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Stroud is about 2 miles west of Petersfield, in Hampshire. We send applicators to Stroud for service penetrations. We work across 723 places in Hampshire, from busy centres to rural villages. Our Portsmouth page has more on work in that area (15 miles or so).
