Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Leave it or put it right?
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is normally a modest job when the openings are accessible. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Converted and older buildings near places like Lower Assendon tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.
Why us?

Fire stopping for commercial buildings in Lower Assendon
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. We match each opening to that detail before any sealant goes in, and raise it with you if it falls outside. If you’re dealing with improvised or mixed-product fire seals and hidden openings found during inspections, we can put it right. Most enquiries from Lower Assendon start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Smaller places such as Lower Assendon still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

What sealant work can’t fix
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Approving the work on behalf of building control
- Gaps in walls that were never built as compartment walls
- Openings that need collars, wraps, batts or boards rather than sealant
If you’re not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.
What we seal
- Cable penetrations
- Linear gaps at wall heads
- Pipe penetrations
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
Different surfaces, different methods
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. Each gap is measured where it is widest against the detail’s limits.
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on, so we check each one.
Fire stopping around Lower Assendon: what changes locally
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. Lower Assendon is about 36 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls.
Large healthcare estates like Townlands Memorial Hospital (1.4 miles south-east of Lower Assendon) change their services often, so penetration seals are worth checking after M&E work. For a building such as Church of St Anne, new heating or data runs are the usual reason penetrations need sealing.

When to call us in Lower Assendon
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.
If one of these sounds familiar, it’s time for a closer look:
- Fire stopping installed outside its tested range
- Penetration schedules that need working through
- Damaged fire seals in risers and voids
- Unsealed joints where partitions meet the slab
For a school such as Rupert House School, penetration sealing fits best at the end of the summer works.
What your quote should include
- Proof of insurance
- Whether primer will be used where the manufacturer specifies it
- Is the sealant right for the movement and the substrate?
- Their pre-qualification and accreditations
Diagnose, treat, sign off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes anything from one day to a planned run of visits, depending on the number of seals and the access, and our waste is bagged and taken away as we go. Rural sites near Lower Assendon 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 raise any questions before we price.
- 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.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
What we need from you
- Share your working hours and any access restrictions
- Let building users know which areas are affected
- Move anything stored against the joints

How do we ask for a quote?
There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.
What affects the price in Lower Assendon
Your fixed quote is built from the real scope. It takes account of:
- Any access equipment needed
- Distance, for remote addresses
- Whether old sealant has to be cut out first
- Induction, permit and paperwork requirements
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.
Sending details for a quote
Diagnosis starts before we arrive. Tell us:
- Whether the building will be occupied during the work
- A wide shot and a close-up of the area
- Approximate linear metres or a joint schedule
- The postcode of the building
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call 01277 525 020 or email a schedule or drawings.
