What the job involves on each surface
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes. We confirm material and size first and tell you if sealant isn’t the right product.
Cables and cable bundles
Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. The detail limits bundle size and the gaps between and around cables and we work within those limits.
Fire stopping in Hayes
No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in, and raise it with you if it falls outside. The enquiries we see most involve fire-rated sealant that has cracked or shrunk back and unsealed openings around new pipes and cables, on service gaps in risers, pipe penetrations and cable penetrations. One point of contact handles commercial sealant work in Hayes from the first photos to the final walk-round, whether it’s one building or several.
Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we will confirm with the quote.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

On site: what to expect
We bring the products specified for the job, along with primers and backing rod. 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. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
What we need from you
- Tell us which areas need to stay in use
- Share your working hours and any access restrictions
- Make sure the joints can be reached
Quotes
Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
Advice
Penetration seals near Hayes
A good number of hotels sit less than 2 miles from Hayes. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail.
In a hotel such as Fountain House Hotel (less than half a mile north-east of Hayes), new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. On estates like Caxton Trading Estate (0.5 miles south of Hayes), the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal. For an estates team at a campus like Brunel University of London, 2.6 miles north-west of Hayes, summer M&E works are usually followed by a round of penetration sealing.

Cost factors for service penetrations
Quotes vary with the job. It mainly depends on:
- Any access equipment needed
- Location, for remote and island sites
- How much there is to seal
- Which sealant the job calls for
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
What we need to price the job
For an accurate fixed quote, we need to understand the site. Send us:
- Any dates the work must fit around
- Approximate linear metres or a joint schedule
- The postcode of the building
- The product your specification calls for
To get a fixed quote, ring 01277 525 020 or email a schedule or drawings. Our quote form is another easy route.
After the work
Your facilities or cleaning team can help the joints last. Share these points with them:
- Foam or ordinary sealant is never a fire-seal repair
- Get seals inspected before ceilings and boxing close
- Look above ceilings when tiles are lifted for other jobs
- Ask the designer to confirm details early on refits
Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job compared with dozens found at once.
Should maintenance staff do it?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Why it’s worth doing now in Hayes
Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first and the building feels the difference. Failed sealant in a building in Hayes can quickly affect neighbours, tenants or the floor below. Putting it right early is less disruptive than dealing with the consequences.
Pricing service penetrations depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.

Questions we’re asked in Hayes
What does the BS 476 change mean for fire-rated sealant in Hayes?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Can you cope with the access rules in a London building?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Do your applicators hold CSCS cards?
Yes. We use CSCS-carded applicators.
Is any job too small?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
