Common questions from Brickendon clients
Is Brickendon too far out for you?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Would you work within a site like Hertford County Hospital?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, with one point of contact.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Can you tell us what fire stopping our building needs?
No. Deciding what is needed sits with the designer, fire engineer and building control. Our role is installing what they specify, to the product’s tested detail.
Fire stopping for commercial buildings in Brickendon
A fire-rated sealant is only one part of a tested system: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and we say so if it doesn’t fit. If you have builders’ foam or ordinary silicone in compartment walls and fire seals cut back for extra cables and never reinstated, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Brickendon is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Smaller places such as Brickendon still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Diagnose, treat, sign off
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Rural sites near Brickendon 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 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.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- Completed areas are checked with you, with the records agreed when we quoted.
Getting the site ready
- Point out any areas we must not close
- Point out parking and an unloading spot
- Send your site hours and access windows

Advice
Cost factors for service penetrations
Quotes vary with the job. It mainly depends on:
- The size and state of each joint
- Travel to remote or island sites
- Quantities, in metres or numbers
- Removal of failed or old sealant
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
Sending details for a quote
We can often quote from photos and a few details. Please tell us:
- The type of building and who uses it
- Drawings or a marked-up plan, if available
- Any dates the work must fit around
- Access details, including height
Need a figure for a tender or a budget? We will quote against your scope and drawings you can plan around. If you have questions first, give us a call on 01277 525 020 or use the quote form.
Different surfaces, different methods
Small ducts
Some fire-rated sealant details cover small ducts. Bigger ducts and fire-resisting ductwork are normally handled with other products.
Cables and cable bundles
New data and power cables are the most common breach we see. Openings around new cables are resealed to the detail, and we tell you if the bundle exceeds what sealant covers.

When something else is needed
We check first that sealant really is the fix. It isn’t the answer for:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Approving the work on behalf of building control
- Fire doors, dampers or other fire safety equipment
Not sure which it is? You can phone 01277 525 020 or use the quote form and we’ll tell you honestly before you book.
What we seal
- Linear gaps at wall heads
- Cable penetrations
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Pipe penetrations
After the work
A few simple habits keep the new joints working:
- Have penetrations checked while they can still be seen
- Check risers and ceiling voids after each round of works
- Check with the data sheet before painting over fire sealant
- Keep product data and details in the fire safety file
Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail.
Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned, and the work runs in step with the M&E.
Service penetrations in Brickendon buildings
In England, Approved Document B covers fire stopping of openings and penetrations. 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. Our part stays the same: the specified product, installed to its tested detail. At about 18 miles from central London, Brickendon 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.
Halls and meeting rooms at places like Holy Cross & St Alban sometimes gain new services, and any compartment wall crossed needs the specified seal. Campus buildings at universities such as University of Hertfordshire, 4 miles west of Brickendon, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. Where a unit on an estate such as Mimram Road Industrial Estate, 2.7 miles north of Brickendon, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.

When to bring in a specialist
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, 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 brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
