Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
How we handle fire stopping in Hackbridge
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. If you are dealing with fire-rated sealant that has cracked or shrunk back and fire-stopping items raised at inspection or handover, we can put it right, on pipe penetrations, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors alike. Facilities teams, main contractors and managing agents in Hackbridge tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
In London, higher-risk residential buildings under the Building Safety Act bring extra scrutiny of fire-stopping records. Our part is installing the specified fire-rated sealant; tell us what records you need and we will confirm with the quote.
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.

Our process
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. All of Greater London is in the ULEZ, and kerbside space in Hackbridge can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
Preparing the site
- Point out parking and an unloading spot
- Let building users know which areas are affected
- Share your working hours and any access restrictions
Ask for a quote
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to phone 01277 525 020 or email the details over with what you know.

Looking after the joints
Once the work is signed off, these steps help:
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Check with the data sheet before painting over fire sealant
- Flag new cables with no seal around them
- File the specified details where the next contractor can find them
Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.
Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small; found late, it can be one of many.
Cost factors for service penetrations
To price the job, we consider:
- Whether old sealant has to be cut out first
- Site requirements such as inductions and permits
- Distance, for remote addresses
- The size and state of each joint
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.
Sending details for a quote
For an accurate fixed quote, we need a clear picture of the site. Send us:
- The site address and postcode
- Photos of the joints, close up and from further back
- When you need the work done
- Asbestos survey details if the building is older
Need a figure for a tender or a budget? We will quote against your scope and drawings you can plan around. For a chat about it beforehand, call 01277 525 020 or email a schedule or drawings.
Signs you need fire stopping in Hackbridge
Openings in fire-resisting walls usually appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Over a few years of fit-outs, a wall can collect a lot of these.
If one of these sounds familiar, it’s time for a closer look:
- Fire-stopping items raised at inspection or handover
- Unsealed joints where partitions meet the slab
- Unsealed penetrations discovered above suspended ceilings
- Fire seals cut back for extra cables and never reinstated
Theatres, wards and plant rooms at sites like The Wilson Hospital, 0.5 miles south-west of Hackbridge, all have compartment walls crossed by services.
Questions to ask before you book
- How joint depth will be controlled
- Whether their applicators hold CSCS cards
- Their pre-qualification and accreditations
- How the joint faces will be prepared and primed
Questions we’re asked in Hackbridge
What happens to BS 476 references for fire stopping in Hackbridge?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Can you work around term dates at a campus such as Kingston University Roehampton Vale Campus?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Do you work in Hackbridge?
Yes. Hackbridge falls within our area, and you can call the office on 01277 525 020 or send photos by email to get started.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Is any job too small?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
How much does the work cost?
Each job is quoted on its own details. For yours, call the office on 01277 525 020 or use the quote form.
When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Fire doors, dampers or other fire safety equipment
- Plastic pipes whose detail calls for a collar or wrap
If you’re not sure, just speak to us on 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

Penetration seals near Hackbridge
Every new tenant in a London building tends to bring new cabling, and with it new holes through compartment walls. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements. A number of hotels sit less than 2 miles from Hackbridge. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.
Where a unit on an estate such as Willow Lane Industrial Estate (0.8 miles south-west of Hackbridge), has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. For a unit at a centre such as Priory Retail Park, which lies north-west of Hackbridge, penetration seals are worth checking after each shop fit.
