Fire stopping in Lanham Green
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
How we handle fire stopping in Lanham Green
Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. We work to the product’s tested detail for every seal. We work on cable penetrations, small duct penetrations where the tested detail allows and service gaps in risers, and the usual reasons a site gets in touch are head-of-wall gaps with no fire seal and fire stopping installed outside its tested range. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Lanham Green is the same: the right product in a properly prepared joint.
Around smaller places like Lanham Green, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
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.

Service penetrations in Lanham Green buildings
Lanham Green has two care or nursing homes no more than 2 miles away. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. Lanham Green is about 39 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal.
Tenant changes at parks like Lanham Business Park (to the north-west of Lanham Green) bring new data and services, and openings through fire-resisting walls need the specified seal. At a college such as Braintree College, 2.8 miles to the north-west of Lanham Green, checking penetration seals after summer M&E works is good practice.
Lanham Green is about 2 miles south-east of Braintree, in Essex. Our applicators travel to Lanham Green for work on service penetrations, handled exactly as we handle every other area. Lanham Green is one of 644 places in Essex on our list. London is covered too, some 39 miles away.

Surface by surface
Linear joints
Joints at the top of partitions may need to move as the slab above deflects. The specified product and backing for that movement are what goes in, with no gaps along the run.
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.
Quoting for work in Lanham Green
What shapes the price:
- The total length or number of joints
- Site requirements such as inductions and permits
- Removal of failed or old sealant
- How accessible the joints are
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
What we need to price the job
There’s no need for a formal survey. These details are enough to start:
- Where the site is, with the postcode
- Drawings or a marked-up plan, if available
- The product your specification calls for
- The type of building and who uses it
A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or ring 01277 525 020 or use the quote form if you’d rather talk the job through.
Leave it or put it right?
An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail, and doing it once, properly, is cheaper. Halls, stores and units around places like Lanham Green may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote when you’re ready.

Signs you need fire stopping in Lanham Green
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls.
Any of the following is a good reason to get the joints checked over:
- Fire-stopping items raised at inspection or handover
- Openings left by services added after handover
- Unsealed joints where partitions meet the slab
- Old intumescent sealant that has split away
In a building such as Parish Church of All Saints, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Common questions from Lanham Green clients
Do you take on work at healthcare sites like Braintree Community Hospital?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can work in a care setting near Lanham Green go ahead while residents are there?
Yes. We agree rooms and times with the manager and work a few areas at a time. Any site rules, from signing in to infection control, are agreed before we start.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
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.
Do you approve fire stopping for building control?
No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. Our part is fitting the specified product to its tested detail.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
