Fire stopping for businesses in New Forest
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
What sets the cost
A fixed quote reflects the actual work. It takes account of:
- Access and working height
- Distance, for remote addresses
- Whether the work must be split into stages
- Induction, permit and paperwork requirements
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Sending details for a quote
The more we know, the firmer the quote. When you get in touch, include:
- A wide shot and a close-up of the area
- The product your specification calls for
- What the building is and how it’s used
- Whether an asbestos survey exists
The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or speak to us on 01277 525 020 or use the quote form if you’d rather talk the job through.
How we handle fire stopping in New Forest
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. Each seal follows the manufacturer’s tested detail. Site teams most often ask us about fire sealant pulled out of the opening and fire-stopping items raised at inspection or handover, across service gaps in risers, cable penetrations and joints between fire-resisting walls and floors. Most enquiries from New Forest start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Around smaller places like New Forest, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- Report damaged or disturbed seals as soon as they’re spotted
- Don’t let anyone top up a fire seal with the wrong product
- Agree the fire-stopping specification before services go in
- Leave fire sealant to cure fully before covering it
Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail, by someone who knows the system.
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.
Should maintenance staff do it?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Common questions from New Forest clients
What happens to BS 476 references for fire stopping in New Forest?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is 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 New Forest too small for you to travel to?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Are you fully insured?
Yes. We are fully insured, including public liability cover.
What if there’s asbestos in the old mastic?
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.
How do I request a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Can you work while the building is occupied?
In most cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
How a job runs
Site rules come first: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you. Rural sites near New Forest may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- We read the specification, drawings or penetration schedule you send 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.
- We apply the specified sealant to the depth and around the services as the detail shows.
- 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
- Have the specification and drawings to hand
- Send asbestos survey details if the building is pre-2000

What the job involves on each surface
Plastic pipes
Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail. We check the pipe material and diameter against the detail before we start.
Metal pipes
Metal pipes conduct heat, so their details often call for extra measures along the pipe, and the tested detail may ask for insulation beyond the wall. If the detail needs something beyond sealant, we tell you.
Why it’s worth doing now in New Forest
Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first, and the other benefits follow. For buildings around smaller places like New Forest, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
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.
