About our fire stopping in Iver Heath
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate and we’d rather say that up front. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on cable penetrations, joints between fire-resisting walls and floors and pipe penetrations, and the usual reasons a site gets in touch are head-of-wall gaps with no fire seal and seals that don’t match their tested detail. Most enquiries from Iver Heath 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.
Around Iver Heath, penetration and linear seals tend to be one-building jobs. With the specification and photographs of the gaps, we can give a fixed quote and bring the right products.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Common questions from Iver Heath clients
How does the move away from BS 476 affect penetration seals in Iver Heath?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Will you take on work at estates like Uxbridge Industrial Park, close to Iver Heath?
Yes. Our area takes in Iver Heath and its surroundings, with estates and business parks such as Uxbridge Industrial Park included. A few photos and the unit address let us price the work.
Is your workmanship covered by a guarantee?
Yes. Workmanship is guaranteed for 12 months on every job.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Is any job too small?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Can you handle several sites?
Yes. A group of buildings can go on one quote, with one point of contact.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.
On site: what to expect
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you. What matters most for a job in Iver Heath is a clear list of what needs doing, so send photographs of each area. A fixed quote follows.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
Getting the site ready
- Send your site hours and access windows
- Explain the parking and delivery arrangements
- Flag any permit to work we will need
Quotes
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

Aftercare for building managers
Problems stay small when the joints are checked regularly. In particular:
- Leave fire sealant to cure fully before covering it
- Get seals inspected before ceilings and boxing close
- Put resealing into every M&E and fit-out package
- Foam or ordinary sealant is never a fire-seal repair
After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.
Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.
Why it’s worth doing now in Iver Heath
Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme which is why earlier is better. For buildings in places like Iver Heath, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

Common problems we fix in Iver Heath
When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.
Most enquiries start with one or more of the following:
- Non-fire-rated filler around services
- Penetration schedules that need working through
- Seals that don’t match their tested detail
- Old intumescent sealant that has split away
Workshops and IT rooms at colleges like Orchard Hill College Park View Centre (to the east of Iver Heath) are re-serviced often, leaving penetrations to seal.
Questions to ask before you book
- Whether their applicators hold CSCS cards
- Proof of insurance
- How they’ll work around occupants
- How long is the guarantee, and what does it include?
Different surfaces, different methods
Plastic pipes
Waste and drainage pipes through floors are a frequent case. The detail decides whether sealant alone is enough.
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest so we know it sits within the tested range.
What affects the price in Iver Heath
The price varies from site to site. It mainly depends on:
- Joint width, depth and condition
- Site requirements such as inductions and permits
- How much there is to seal
- Whether old sealant has to be cut out first
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.
What we need to price the job
However big the job, these details speed things up:
- Rough lengths or quantities, or drawings if you have them
- Specification clauses that apply
- Your programme or deadline
- How the joints are reached, and at what height
Need a figure for a tender or a budget? We’ll quote against your scope and drawings you can plan around. For a chat about it beforehand, give us a call on 01277 525 020 or email the details over.
Fire-rated sealing for Iver Heath buildings
At about 19 miles from central London, Iver Heath is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls, and the gaps need sealing with the specified product. A 2-mile radius around Iver Heath takes in several hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.
Older community buildings such as Church of St Margaret that have been rewired or given new heating can have service gaps through walls worth checking against the specification. Hospital estates such as Spire Thames Valley Hospital, 2.2 miles to the west of Iver Heath, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
