Fire stopping for Howe Street sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Surface by surface
Small ducts
Ducts are only sealed with sealant where the detail allows it. The ductwork, its supports and any dampers are for the ductwork contractor.
Cables and cable bundles
Data cabling added after handover is a regular cause of open service penetrations. We reseal around them to the specified detail.
Fire stopping in Howe Street
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Other openings need collars, wraps, batts, pillows or boards. If the detail calls for something other than sealant, we say so rather than force sealant into it. If you are dealing with non-fire-rated filler around services and improvised or mixed-product fire seals, we can put it right, on small duct penetrations where the tested detail allows, pipe penetrations and joints between fire-resisting walls and floors alike. Whether you call it commercial sealant work, mastic application or joint sealing, in Howe Street it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller places like Howe Street, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
A 12-month guarantee applies to all our work in Essex. Should something we installed fail, phone 01277 525 020 or email us and we’ll come back to it.

Diagnose, treat, sign off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For work around Howe Street, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- We gun the sealant in to the specified depth around each service and tool it.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Preparing the site

Cost factors for service penetrations
Each job is priced on its own details. The things that drive the figure:
- How accessible the joints are
- Which sealant the job calls for
- The size and state of each joint
- The total length or number of joints
Access can matter as much as the joints themselves: 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.
Before you send an enquiry
A few photos plus some basic facts will normally do. Please tell us:
- The asbestos register, for older buildings
- Approximate linear metres or a joint schedule
- The postcode of the building
- A wide shot and a close-up of the area
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or call the office on 01277 525 020 or email us if you’d rather talk the job through.
Maintenance after handover
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Keep product data and details in the fire safety file
- Don’t let anyone top up a fire seal with the wrong product
- Ask the designer to confirm details early on refits
- Flag new cables with no seal around them
Once the seals are in, tell other trades they exist and must not be disturbed. If a seal has to be opened for a new service, it should be reinstated to the same detail, by someone who knows the system.
Ask every contractor who works in risers or voids to report openings they create. It costs little and catches breaches early.
Your questions answered
Is a hospital such as Broomfield Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is a smaller place like Howe Street outside your area?
Not at all. Howe Street is within our area. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
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 it all comes out first.
Is colour matching possible?
That depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.
Which sealant will you use?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
What we can’t put right
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:
- Deciding what a wall or floor needs, which belongs to the designer
- Reviewing a building’s overall fire safety
- Issuing fire ratings or certificates for seals
If in doubt, call the office on 01277 525 020 or email drawings and photos and we will say what we think.
Surfaces we seal
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Pipe penetrations
- Linear gaps at wall heads
- Cable penetrations
- Joints between fire-resisting walls and floors

Leave it or put it right?
An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. The specified fire seal closes the gap for all of these. Around Howe Street, it’s better to renew all the failing joints at once. Send photos of each area and we will quote for the lot.

Penetration seals near Howe Street
For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Howe Street lies roughly 32 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.
For a building such as Church of SS Mary and Laurence, new heating or data runs are the usual reason penetrations need sealing. In a school such as Chelmer Valley High School, fire-rated sealant goes in around service penetrations where it is specified. Residences at universities like Anglia Ruskin University (4.3 miles south of Howe Street) have compartment walls that must be resealed whenever services change.
