Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Why it’s worth doing now in Hedsor
Open penetrations multiply: each new service adds to the list. A schedule that is dealt with regularly stays manageable and avoids a much larger catch-up later. Halls, stores and units around places like Hedsor may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
A quote for service penetrations depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Fire stopping for commercial buildings in Hedsor
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. We work on pipe penetrations, linear gaps at wall heads and joints between fire-resisting walls and floors, and what we are called in for most is fire-stopping items raised at inspection or handover and expanding foam used as fire stopping. A specialist sealant contractor works differently from a general builder: in Hedsor, that means joint design, primers and backing rod as standard.
A job near Hedsor is typically planned around one visit, 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 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

From enquiry to sign-off
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, and each area is checked before we leave it. Rural sites near Hedsor may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- 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.
- 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.
What we need from you
- Let us know about inductions and permits
- Tell us your opening times and when work is allowed
- Tell us which areas need to stay in use

Advice
What sealant work can’t fix
Being straight saves everyone time. New sealant won’t cure:
- Signing off or certifying a building’s fire stopping
- Walls or floors that aren’t fire-resisting to begin with
- Reviewing a building’s overall fire safety
If you are not sure, just call the office on 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.
Surfaces we seal
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Cable penetrations
- Linear gaps at wall heads
Questions about Hedsor
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Hedsor?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Is Hedsor too far out for you?
No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Do you guarantee your work?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, but not damage, misuse or other trades’ work.
What happens if old sealant might contain asbestos?
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 if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
When can you be on site?
We’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.
How soon can the area be used again?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Different surfaces, different methods
Risers and ceiling voids
Voids hide a lot of unsealed openings. We follow your schedule area by area and tell you about openings outside the list.
Metal pipes
Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on, so we check each one.

Other services in Hedsor
Do you need fire stopping in Hedsor?
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, which then have to be put right.
It’s worth sending us details if you spot any of the following:
- Unsealed joints where partitions meet the slab
- Openings found when ceilings come down for a refit
- Service penetrations left open after M&E works
- Fire-rated sealant that has cracked or shrunk back
Older community buildings such as Cores End United Reformed Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

At about 26 miles from central London, Hedsor is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls. For England, the fire stopping of penetrations is dealt with in 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. We install whatever has been specified, to the product’s tested detail.
Theatres, wards and plant rooms at sites like Marlow Community Hospital (3.6 miles west of Hedsor) all have compartment walls crossed by services. Residences at universities like Buckinghamshire New University (4.6 miles north-west of Hedsor) have compartment walls that must be resealed whenever services change.

General trades versus a specialist
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
