Fire stopping in Netteswell, done properly
No fire sealant works on its own: 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 raise it with you if it falls outside. We work on small duct penetrations where the tested detail allows, cable penetrations and pipe penetrations, and what we’re called in for most is builders’ foam or ordinary silicone in compartment walls and fire-stopping items raised at inspection or handover. Looking for mastic applicators who cover Netteswell? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Around Netteswell, penetration and linear seals tend to be one-building jobs. Send the specification, drawings or photographs of the openings and we will quote to suit.
A 12-month guarantee applies to all our work. If an installation problem shows up, call 01277 525 020 or send photos by email and we will arrange a return visit.

When it isn’t the sealant
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Fire risk assessments, a job for a competent assessor
- Openings that need collars, wraps, batts or boards rather than sealant
- Designing or specifying fire stopping, which sits with the designer or fire engineer
If in doubt, ring 01277 525 020 or use the quote form and we will say what we think.
What we seal
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Pipe penetrations
- Cable penetrations
- Service gaps in risers
Surface by surface
Small ducts
We seal around ducts only within what the tested detail covers. The ductwork, its supports and any dampers are for the ductwork contractor.
Cables and cable bundles
Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. Bundle size, cable type and the space between cables all matter.
What we’re called out for in Netteswell
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in, which then have to be put right.
Site and facilities staff are often the first to spot these:
- Head-of-wall gaps with no fire seal
- Openings found when ceilings come down for a refit
- Expanding foam used as fire stopping
- Service penetrations left open after M&E works
At a college such as Harlow College (under half a mile west of Netteswell), checking penetration seals after summer M&E works is good practice.

Building owners, agents and FMs in Netteswell
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Compartments and services around Netteswell
There are a number of hotels within about 2 miles of Netteswell. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. Netteswell lies roughly 21 miles out from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls.
In a building such as St Andrew's Methodist Church, any service penetration through a fire-resisting wall should be sealed to the specified detail. At a retail site such as Oaks Retail Park, which lies north of Netteswell, walls between units may be fire-resisting, so services added in a refit need the specified seal.

What else we do in Netteswell
Doing it in-house
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Diagnose, treat, sign off
Site rules come first: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For a site in Netteswell, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- We ask for the product and detail your designer has specified.
- We sort the openings by the detail each one needs.
- 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
- Send any specification or drawings in advance
- Point out parking and an unloading spot
- Agree which areas must stay open
Ask for a quote
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or send details through our quote form.

Netteswell: questions and answers
Can you work around term dates at a campus such as Harlow College?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
What does the BS 476 change mean for fire-rated sealant in Netteswell?
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. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
What’s the quickest route to a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
Can you work while the building is occupied?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
Can weather delay the job?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Is colour matching possible?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators, which many sites require.
