What we are called out for in Rivenhall
Mixing products or improvising a detail breaks the link with the test evidence. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.
If one of these sounds familiar, it’s time for a closer look:
- Builders’ foam or ordinary silicone in compartment walls
- Open linear gaps along the top of fire-resisting walls
- Openings found when ceilings come down for a refit
- Penetration schedules that need working through
In a hotel such as Rivenhall Hotel, 1 mile south-east of Rivenhall, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.
What to look for in a quote
- How the joint faces will be prepared and primed
- Their public liability cover
- How joint depth will be controlled
- Which product they’ll use, and why it suits the joint
About our fire stopping in Rivenhall
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 using the product and detail it sets out. Where there isn’t one, the designer or fire engineer needs to set one first. We work on service gaps in risers, small duct penetrations where the tested detail allows and linear gaps at wall heads, and the failures we are asked to look at most are fire stopping installed outside its tested range and penetration schedules that need working through. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Rivenhall, that means joint design, primers and backing rod as standard.
Around smaller places like Rivenhall, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. 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 a joint we sealed fails because of how it was installed, we come back and put it right.

What happens if it’s left?
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. Converted and older buildings near places like Rivenhall tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

Where services cross fire walls in Rivenhall
Rivenhall is about 39 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Either way, we install the specified product to its tested detail.
For a building such as Church of St Mary and All Saints, new heating or data runs are the usual reason penetrations need sealing. Where a unit on an estate such as Gold Key Industrial Estate, which lies east of Rivenhall, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.
Rivenhall is about 2 miles north of Witham, in Essex. Our applicators travel to Rivenhall for work on service penetrations. Rivenhall is one of 644 places in Essex on our list for service penetrations. London is covered too, some 39 miles away.

Keeping the joints sound
Problems stay small when the joints are checked regularly. Specifically:
- Ask the designer to confirm details early on refits
- File the specified details where the next contractor can find them
- Put resealing into every M&E and fit-out package
- Include service cupboards in routine inspections
Don’t patch a fire-rated seal with anything outside its tested detail. A repair should use the original product, installed the same way, or a new specification from the designer.
On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and installation follows the programme.
Our process
We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, 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 Rivenhall need work, visits can be combined. You will have a fixed quote before work starts.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
Preparing the site
- Move anything stored against the joints
- Flag any permit to work we’ll need
- Let building users know which areas are affected

How the quote is worked out
These are the things that shape the price:
- Phasing around occupants
- Distance, for remote addresses
- How much there is to seal
- Joint width, depth and condition
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
Details that help us quote
We can often quote from photographs and a few details. It helps to include:
- How the joints are reached, and at what height
- Approximate linear metres or a joint schedule
- Clear photos of the problem areas
- The asbestos register, for older buildings
Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote that you can work with. If you have questions first, give us a call on 01277 525 020 or send photos by email.
Questions we are asked in Rivenhall
Can you work at a site such as Gold Key Industrial Estate, by Rivenhall?
Yes, sites like Gold Key Industrial Estate are within our area, along with the rest of Rivenhall. A few photos and the unit address let us price the work.

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Is the BS 476 change in 2029 relevant to fire stopping?
In England, references to the older BS 476 national classes are being removed from Approved Document B from 2 September 2029, with transitional arrangements set by the Government. The European route, BS EN 13501-2, then applies. Product selection stays with your designer.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, with one point of contact.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

What else we do in Rivenhall
How the job changes by surface
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail and we confirm each before sealing.
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes, though larger ones normally call for a collar or wrap. We check the pipe material and diameter against the detail before we start.
