Fire stopping for businesses in Boars Hill
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Fire stopping in Boars Hill, done properly
Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it, matching the product and detail it names. With no specification in place, the first step sits with your designer or fire engineer, not with us. The enquiries we see most involve non-fire-rated filler around services and fire-rated sealant that has cracked or shrunk back, on pipe penetrations, joints between fire-resisting walls and floors and linear gaps at wall heads. One point of contact handles commercial sealant work in Boars Hill from the first photographs to the final walk-round, for single jobs and planned programmes alike.
For a smaller site near Boars Hill, we plan to do all the penetrations in one go, with the specification and photos sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Our workmanship is guaranteed for 12 months, in Boars Hill as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Common questions from Boars Hill clients
Can you work on a hospital site such as Littlemore Hospital?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can work in a care setting near Boars Hill go ahead while residents are there?
Yes, with the manager deciding the order and timing of rooms. Tell us about any infection-control or safeguarding requirements and we’ll work to them.
How long does a job like this take?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
How long do sealant joints last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Do you have public liability insurance?
Yes. We’re fully insured, and the certificate can go with your quote.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Signs you need fire stopping in Boars Hill
Plenty of openings were simply never closed because they sat out of sight above a ceiling or inside a riser. Inspections, refurbishments and ceiling access normally bring them to light.
Clients normally get in touch after noticing one or more of the following:
- Open linear gaps along the top of fire-resisting walls
- Expanding foam used as fire stopping
- Openings left by services added after handover
- Seals disturbed by maintenance and left open
On a site such as Wootton Business Park, which lies west of Boars Hill, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.

Keeping the joints sound
Cleaning and maintenance staff play a part too. Pass these on to them:
- File the specified details where the next contractor can find them
- Keep general-purpose fillers away from compartment walls
- Agree the fire-stopping specification before services go in
- Report damaged or disturbed seals as soon as they’re spotted
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted, and the data sheet says which.
Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.
Leave it or put it right?
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. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. For buildings around smaller places like Boars Hill, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Diagnose, treat, sign off
We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. If others near Boars Hill need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- 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.
Getting the site ready
- Explain the parking and delivery arrangements
- Let building users know which areas are affected
- Tell us which areas need to stay in use

Advice
Doing it in-house
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Surface by surface
Cables and cable bundles
New data and power cables are the most common breach we see. We reseal around them to the specified detail.
Small ducts
We seal around ducts only within what the tested detail covers. Dampers and ductwork systems themselves are outside our work.
