Fire stopping for commercial buildings in Shellow Bowells
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate and we’d rather say that up front. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on pipe penetrations, linear gaps at wall heads and service gaps in risers, and the failures we are asked to look at most are seals disturbed by maintenance and left open and expanding foam used as fire stopping.

What we can’t put right
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Gaps in walls that were never built as compartment walls
- Plastic pipes whose detail calls for a collar or wrap
- Writing the fire-stopping specification

FAQs: Shellow Bowells
How does the move away from BS 476 affect penetration seals in Shellow Bowells?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Is hospital work, at somewhere like Chelmsford and Essex Hospital, something you do?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Do your applicators hold CSCS cards?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
What hours do you work?
Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Penetration seals near Shellow Bowells
Central London is about 25 miles from Shellow Bowells. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls; the gaps need the specified seal. For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. We install whatever has been specified, to the product’s tested detail.
At a university such as Writtle University College Cow Watering Campus, 3.2 miles to the east of Shellow Bowells, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. Wherever services are added at a hospital such as Chelmsford and Essex Hospital, 5.7 miles to the east of Shellow Bowells, the compartment line has to be made good with the specified product. Older community buildings such as Church of St Peter and St Paul that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Different surfaces, different methods
Metal pipes
Heat travels along metal pipework, and some details add wrapping or a set length of insulation. We follow whatever the detail requires and flag anything we can’t match.
Small ducts
Some fire-rated sealant details cover small ducts. Larger or fire-rated ductwork usually needs a different solution set by the designer and we flag that rather than guess.
On site: what to expect
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. If others near Shellow Bowells need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Preparing the site
- Agree which areas must stay open
- Share the asbestos register for older buildings
- Tell staff and tenants when we’ll be in
Quotes
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.
Advice
Site staff or a sealant specialist?
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
What sets the cost
We price every job individually. The main factors are:
- Phasing around occupants
- How much existing material needs removing
- Distance, for remote addresses
- Specialist products, such as fire-rated or hygienic sealants
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Before you send an enquiry
However big the job, these details speed things up:
- What the building is and how it’s used
- When you need the work done
- The product your specification calls for
- Where the site is, with the postcode
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
