Questions about High Ongar
Is a smaller place like High Ongar outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
What does the BS 476 change mean for fire-rated sealant in High Ongar?
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.
Is your workmanship covered by a guarantee?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Fire stopping in High Ongar
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. We work to the product’s tested detail for every seal rather than guesswork. If you have open linear gaps along the top of fire-resisting walls and expanding foam used as fire stopping, we can help. Most enquiries from High Ongar start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
For a smaller site near High Ongar, we plan to do all the penetrations in one go, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Every job we finish is backed by a 12-month workmanship guarantee, in High Ongar as everywhere else we work. If our installation lets you down in that time, we return and fix it.

When it isn’t the sealant
Being straight saves everyone time. Fresh joints won’t solve:
- Large openings beyond what any sealant detail covers
- Issuing fire ratings or certificates for seals
- Construction that lacks the fire resistance the seal relies on
If you are not sure, just call 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.
Joints and surfaces we work on
- Linear gaps at wall heads
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Cable penetrations
When to bring in a specialist
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Keeping the joints sound
To get the most from the new sealant:
- Include service cupboards in routine inspections
- Get seals inspected before ceilings and boxing close
- Flag new cables with no seal around them
- Foam or ordinary sealant is never a fire-seal repair
Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.
Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.
Building owners, agents and FMs in High Ongar
If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.
Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
Different surfaces, different methods
Linear joints
Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement, with no gaps along the run.
Drylining partitions
Service holes through plasterboard are frequently oversized or ragged. If the gap exceeds the tested range, sealant alone won’t do, and the detail may call for board patching or another product.
How a job runs
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes a single visit for a short list of penetrations, or a phased programme for a whole building, and we clear our waste as we work. Jobs in and around smaller places like High Ongar are usually planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- 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.
- If an opening needs something other than sealant, we tell you instead of improvising.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- For older buildings, check the asbestos register before work
- Let us know about inductions and permits
Getting a fixed quote
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to speak to us on 01277 525 020 or use the quote form.

Where services cross fire walls in High Ongar
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. We install whatever has been specified, to the product’s tested detail. High Ongar is about 21 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls; the gaps need the specified seal.
Schools such as High Ongar Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. Halls and meeting rooms at places like Church of St Mary the Virgin sometimes gain new services, and any compartment wall crossed needs the specified seal. Where a unit on an estate such as Hallsford Bridge Industrial Estate (0.9 miles south of High Ongar), has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.
High Ongar is about 6 miles north of Brentwood, in Essex. Any commercial site in High Ongar is covered, whether it’s a single job or part of a planned programme. High Ongar is one of 644 places we cover in Essex. London is covered too, around 21 miles from High Ongar.
