How we handle fire stopping in Hampton Hill
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate and we’d rather say that up front. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. We work on pipe penetrations, small duct penetrations where the tested detail allows and linear gaps at wall heads, and what we’re called in for most is builders’ foam or ordinary silicone in compartment walls and fire seals cut back for extra cables and never reinstated. Whoever orders the work in Hampton Hill, the brief is usually the same: 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’ll confirm with the quote.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Why deal with it now?
Inspections and handover checks often pick up fire stopping. Late discoveries can delay handover while openings are reopened and resealed which is why earlier is better. In Hampton Hill, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
Pricing service penetrations depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Diagnose, treat, sign off
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes anything from one day to a planned run of visits, depending on the number of seals and the access, and our waste is bagged and taken away as we go. Planning a London job such as one in Hampton Hill starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- 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.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Before we start on site
- Point out parking and an unloading spot
- Share your working hours and any access restrictions
- Point out any areas we must not close

How the job changes by surface
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 usually call for a collar or wrap. We check the pipe material and diameter against the detail before we start.
Small ducts
Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products, and we will say if that applies.
FAQs: Hampton Hill
What does the BS 476 change mean for fire-rated sealant in Hampton Hill?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Is hospital work, at somewhere like Teddington Memorial Hospital, something you do?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
When is resealing likely to be due?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Can the building stay open while you work?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
How long does a typical visit take?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
What do you charge?
Every job gets its own fixed quote. To get one, call 01277 525 020 or send details through our quote form with a description of the work.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators, as many construction sites ask for.

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Compartments and services around Hampton Hill
For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. Either way, we install the specified product to its tested detail. Hampton Hill has plenty of hotels close by, all within 2 miles. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.
Where a unit on an estate such as Holly Road Industrial Estate, less than half a mile south-west of Hampton Hill, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. Residences at universities like St Mary's University (1.1 miles north-east of Hampton Hill) have compartment walls that must be resealed whenever services change.

Looking after the joints
Keep the joints in good shape with a few simple steps:
- Arrange inspection before areas are covered up
- Foam or ordinary sealant is never a fire-seal repair
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Check risers and ceiling voids after each round of works
New services after handover are a common way fire stopping gets breached. A short check at the end of each job saves a long hunt later.
Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job compared with dozens found at once.

Common problems we fix in Hampton Hill
When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.
Things that usually lead to an enquiry:
- Openings left by services added after handover
- Non-fire-rated filler around services
- Old intumescent sealant that has split away
- Fire stopping installed outside its tested range
Theatres, wards and plant rooms at sites like Teddington Memorial Hospital, 0.6 miles east of Hampton Hill, all have compartment walls crossed by services.
