How we handle fire stopping in Colbury
A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow. Site teams most often ask us about fire sealant pulled out of the opening and head-of-wall gaps with no fire seal, on joints between fire-resisting walls and floors, 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: in Colbury, that means joint design, primers and backing rod as standard.
A job near Colbury is typically planned around one visit, with the specification and photographs sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Your questions answered
Is a smaller place like Colbury outside your area?
No. Places such as Colbury are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Does your area include sites such as Rushington Business Park, near Colbury?
Yes. We cover Colbury and the area around it, including industrial estates, business parks and retail parks such as Rushington Business Park. Send details of the unit and the work through our quote form for a quick quote.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Do you certify or sign off fire stopping?
No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. We work to the specification and the manufacturer’s installation guidance, and any records you need can be confirmed with the quote.
What changes on 2 September 2029?
From 2 September 2029, Approved Document B in England drops its references to BS 476 classes, subject to the Government’s transitional arrangements. After that, the European classification under BS EN 13501-2 is the route. Your designer will choose products with the right evidence.
Maintenance after handover
After handover, these steps help:
- Get seals inspected before ceilings and boxing close
- Check risers and ceiling voids after each round of works
- Ask which product is in place before decorating
- Record which product was used where
Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted, so check the product data first.
Keep a register of where seals are and what they are made of. It tells the next contractor exactly what to reinstate, and it helps at inspections.
When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Walls or floors that aren’t fire-resisting to begin with
- Writing the fire-stopping specification
- Issuing fire ratings or certificates for seals
If in doubt, call 01277 525 020 or email the details over and we’ll say what we think.
What we seal
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Service gaps in risers
- Cable penetrations
- Small duct penetrations where the tested detail allows
Compartment walls and floors in Colbury
Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Colbury has seven 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.
Campus buildings at universities such as Southampton Solent University, 4.6 miles east of Colbury, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. On a hospital site such as Tatchbury Mount Hospital, which lies north-west of Colbury, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
Colbury is about 1 mile south of Totton, in Hampshire. Businesses, contractors and managing agents in Colbury use us for work on service penetrations. Colbury is one of 723 places we cover in Hampshire.

Building owners, agents and FMs in Colbury
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
When to call us in Colbury
Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.
Clients usually get in touch after noticing something like this:
- Hidden openings found during inspections
- Old intumescent sealant that has split away
- Fire seals cut back for extra cables and never reinstated
- Fire stopping installed outside its tested range
At a college such as Totton College, 1.5 miles to the north of Colbury, checking penetration seals after summer M&E works is good practice.
Questions to ask before you book
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How the existing material will be dealt with
- Their pre-qualification and accreditations
- Will RAMS and insurance details be available?
Why act early in Colbury
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. Older rural buildings around Colbury move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
