About our fire stopping in Clothall
No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths 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. The enquiries we see most involve service penetrations left open after M&E works and expanding foam used as fire stopping, across service gaps in risers, pipe penetrations and linear gaps at wall heads. For commercial sealant work in Clothall, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
For a smaller site near Clothall, we plan to do all the penetrations in one go, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Work for main contractors and building owners
If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
When to bring in a specialist
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
What happens if it’s left?
Open service penetrations matter on ordinary days, not just in a fire: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first, and the other benefits follow. One visit to deal with every failing joint makes more sense than several trips to a place like Clothall, rather than one at a time. Send photographs of each area and we will quote for the lot.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

Fire stopping around Clothall: how the place shapes the job
Fire stopping of openings and penetrations in England falls under Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Either way, we install the specified product to its tested detail. At about 33 miles from central London, Clothall is within reach of the capital. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.
Holiday works at schools like Weston Primary School often leave service openings to seal before pupils return. Wherever services are added at a hospital such as Lister Hospital, 4.1 miles south-west of Clothall, the compartment line has to be made good with the specified product.
Clothall is about 3 miles east of Letchworth, in Hertfordshire. We cover commercial sites throughout Clothall, whether it’s a single job or part of a planned programme. Our Hertfordshire coverage takes in 371 places, from busy centres to rural villages. We also cover London, some 33 miles away.
We cover the SG7 postcode districts for service penetrations. If your building is just outside Clothall, we cover Weston (1 mile south-west), Wallington (2 miles north-east), Baldock (2 miles north-west), St Nicholas (3 miles south) and Rooks Nest (4 miles south-west). Bigger towns within reach include Stevenage (4 miles south), Bishop's Stortford (15 miles south-east), Welwyn Garden City (12 miles south), Harpenden (14 miles south-west), Hitchin (5 miles west) and Hatfield (15 miles south).

What else we do in Clothall
Signs you need fire stopping in Clothall
Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it, so it has to come out.
Any of the following is a good reason to get the joints checked over:
- Non-fire-rated filler around services
- Fire seals cut back for extra cables and never reinstated
- Fire-rated sealant that has cracked or shrunk back
- Unsealed openings around new pipes and cables
Halls and meeting rooms at places like Church of St Mary sometimes gain new services, and any compartment wall crossed needs the specified seal.
Questions to ask before you book
- Whether old or failed sealant will be cut out, not overlaid
- Which product they’ll use, and why it suits the joint
- Proof of insurance
- Will RAMS and insurance details be available?
Different surfaces, different methods
Risers and ceiling voids
Service risers and the voids above ceilings are where openings collect. Access is often tight, so we agree it with you in advance, including keys, permits and any isolations.
Small ducts
We seal around ducts only within what the tested detail covers. Dampers and ductwork systems themselves are outside our work.
Common questions from Clothall clients
Is Letchworth Gateway Retail Park, near Clothall, within your area?
Yes, sites like Letchworth Gateway Retail Park are within our area, along with the rest of Clothall. Photos and a short description are enough for a first look.
Is hospital work, at somewhere like Lister Hospital, something you do?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
What changes on 2 September 2029?
For buildings in England, Approved Document B removes BS 476 references from 2 September 2029. Classification to BS EN 13501-2 becomes the expected evidence, though transitional rules apply. In Scotland, the Technical Handbook sets its own guidance.
Do you have third-party installer accreditation for fire stopping?
No. We are not members of a third-party fire-stopping installer scheme. Our credentials are CHAS accreditation, Constructionline membership and CSCS-carded applicators, and we are fully insured. If your contract requires third-party installer certification, we are not the right fit for that package.
Will you come and look before quoting?
It depends on the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs normally get a visit.
What’s the quickest route to a quote?
There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
How long does a typical visit take?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
