Fire stopping for Bishop's Stortford sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Aftercare for building managers
Cleaning and maintenance staff play a part too. Pass these on to them:
- Look above ceilings when tiles are lifted for other jobs
- Keep general-purpose fillers away from compartment walls
- Treat an open penetration as a priority repair
- Check with the data sheet before painting over fire sealant
After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail using the same product.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job compared with dozens found at once.
About our fire stopping in Bishop's Stortford
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no 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 joints between fire-resisting walls and floors, and what we are called in for most is service penetrations left open after M&E works and openings found when ceilings come down for a refit. A single leaking joint is often how a building in Bishop's Stortford first comes to us: we look at the rest while we are there and tell you what we find.
In a town such as Bishop's Stortford, fire-rated sealing is often needed in schools, surgeries, care homes, offices and flats above shops. Whenever new services go through those walls, the gaps need sealing with the specified product.
A 12-month guarantee applies to all our work in Hertfordshire. Should something we installed fail, speak to us on 01277 525 020 or email the details over and we will come back to it.

Common problems we fix in Bishop's Stortford
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls and later need putting right.
If one of these sounds familiar, it’s time for a closer look:
- Fire sealant pulled out of the opening
- Openings left by services added after handover
- Openings found when ceilings come down for a refit
- Fire stopping installed outside its tested range
Halls and meeting rooms at places like Church of St Michael sometimes gain new services, and any compartment wall crossed needs the specified seal.

On site: what to expect
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. In a town such as Bishop's Stortford, most jobs are single buildings. Your photos, drawings or a site visit come first, followed by a fixed quote.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Before we start on site
- Make sure the joints can be reached
- Tell staff and tenants when we’ll be in
- Point out any areas we must not close

Advice
Why it’s worth doing now in Bishop's Stortford
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. In Bishop's Stortford, as anywhere, the simplest time to fix a failed joint is before it leaks. After a leak, there’s drying, repairs and redecoration on top.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Cost factors for service penetrations

- Working within restricted access windows
- Location, for remote and island sites
Pricing service penetrations depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

A good diagnosis starts with the right details. Tell us:
