Fire stopping for commercial buildings in Harestock
Most of our fire stopping work happens after the building is up. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, and they are easy to forget. Those on your schedule are closed with the specified product. Site teams most often ask us about open linear gaps along the top of fire-resisting walls and fire seals cut back for extra cables and never reinstated, on service gaps in risers, small duct penetrations where the tested detail allows and pipe penetrations. One point of contact handles commercial sealant work in Harestock from the first photos to the final walk-round, for single jobs and planned programmes alike.
Converted and extended buildings around places like Harestock can mix old and new construction, so it’s worth confirming the wall or floor type before choosing the seal. We match the product to the substrate and service, and say so if a collar, wrap or batt is the specified item.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Signs you need fire stopping in Harestock
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 can leave the hole behind. Across several fit-outs, the openings add up.
If one of these sounds familiar, it’s time for a closer look:
- Expanding foam used as fire stopping
- Fire sealant pulled out of the opening
- Unsealed openings around new pipes and cables
- Snag lists that include open service penetrations
Campus buildings at universities such as University of Winchester (1.5 miles south of Harestock) see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.
What to look for in a quote
- Health and safety accreditation such as CHAS
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Which product they’ll use, and why it suits the joint
- How the joint faces will be prepared and primed
Cost factors for service penetrations
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Induction, permit and paperwork requirements
- Distance, for remote addresses
- How much existing material needs removing
- Specialist products, such as fire-rated or hygienic sealants
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.
What we need to price the job
Whether it’s one area or a whole building, these details speed things up:
- Rough lengths or quantities, or drawings if you have them
- The site address and postcode
- Photos of the joints, close up and from further back
- What the building is and how it’s used
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
Where services cross fire walls in Harestock
The area within 2 miles of Harestock holds a good number of hotels. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product. 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.
For a unit at a site such as Wykeham Industrial Estate, 1.8 miles to the south-east of Harestock, new power or data runs between office and warehouse can breach a compartment wall. On a hospital site such as Sarum Road Hospital (BMI), which lies south of Harestock, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

What else we do in Harestock
What the job involves on each surface
Small ducts
Some fire-rated sealant details cover small ducts. Bigger ducts and fire-resisting ductwork are normally handled with other products.
Drylining partitions
Drylined fire walls are tested in a particular build-up. The sealant detail has to be tested in that wall type, with the stated board layers first.
On site: what to expect
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If neighbouring businesses or buildings around Harestock need work too, visits can be combined. Tell us your site hours and we will plan around them.
- First we go through the drawings, schedule or specification for the seals.
- 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.
- 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.
What we need from you
- Tell us your opening times and when work is allowed
- Agree which areas must stay open
- Explain the parking and delivery arrangements

Advice
FAQs: Harestock
Can you work on a hospital site such as Sarum Road Hospital (BMI)?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can you work at a site such as Wykeham Industrial Estate, by Harestock?
Yes. We cover Harestock and the area around it, including industrial estates, business parks and retail parks such as Wykeham Industrial Estate. Photos and a short description are enough for a first look.
Do you offer coloured sealant?
That depends on the product specified. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
Do you have public liability insurance?
Yes. We’re fully insured, including public liability cover.
Do you have third-party installer accreditation for fire stopping?
No. We don’t hold a third-party fire-stopping installer certificate. We are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded. Where a client or main contractor requires a scheme member, we will say so right away rather than waste your time.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Do you need to see the site first?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
What we can’t put right
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Issuing fire ratings or certificates for seals
- Fire risk assessments, a job for a competent assessor
- Large openings beyond what any sealant detail covers
Not sure which it is? You can call 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Cable penetrations
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
