Common questions from Perry Green clients
Do you cover business parks and estates near Perry Green, such as Lanham Business Park?
Yes. Our area takes in Perry Green and its surroundings, with estates and business parks such as Lanham Business Park included. Photos and a short description are enough for a first look.
Is a smaller place like Perry Green outside your area?
Not at all. Perry Green is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
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.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, and you deal with one contact throughout.
Can you tell us what fire stopping our building needs?
No. Deciding what is needed sits with the designer, fire engineer and building control. Our role is fitting the specified fire-rated sealant, following the maker’s tested details.
Can you send site paperwork?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
How much does the work cost?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote.
Fire stopping for commercial buildings in Perry Green
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We hold no third-party fire-stopping installer certificate and we’d rather say that up front. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. Site teams most often ask us about unsealed joints where partitions meet the slab and improvised or mixed-product fire seals, across linear gaps at wall heads, service gaps in risers and pipe penetrations. A single leaking joint is often how a building in Perry Green first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
A job near Perry Green is typically planned around one visit, so send the specification and photographs first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Maintenance after handover
Regular inspection catches problems early. Specifically:
- Ask the designer to confirm details early on refits
- Keep general-purpose fillers away from compartment walls
- Keep product data and details in the fire safety file
- Arrange inspection before areas are covered up
Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.
Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.
Surface by surface
Plastic pipes
Plastic pipes soften and collapse in a fire. Some intumescent sealants are tested on smaller plastic pipes, though larger ones usually call for a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.
Masonry and concrete
Many seals are made in blockwork, brickwork or concrete slabs. Dust and loose debris are cleared out of the opening, with backing added if the detail requires it.
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. For work around Perry Green, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- 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.
What we need from you
- Point out any areas we must not close
- Arrange parking or a loading space
- Send asbestos survey details if the building is pre-2000
Getting a fixed quote
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Compartment walls and floors in Perry Green
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. Our part stays the same: the specified product, installed to its tested detail. Perry Green is about 40 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.
For a building such as Parish Church of the Holy Trinity, new heating or data runs are the usual reason penetrations need sealing. Large healthcare estates like William Julien Courtauld Hospital (to the west of Perry Green) change their services often, so penetration seals are worth checking after M&E work.
Perry Green is about 3 miles south-east of Braintree, in Essex. Across the CM77 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Perry Green is one of 644 places we cover in Essex for service penetrations. Our London page has more on work in that area.

A short drive away, we cover Colchester (12 miles east), Chelmsford (11 miles south-west), Braintree (3 miles north-west), Maldon (10 miles south), Witham (5 miles south) and Camulodunum (11 miles east).

Common problems we fix in Perry Green
Plenty of openings were simply never closed because they sat out of sight above a ceiling or inside a riser. Inspections, refurbishments and ceiling access usually bring them to light.
Any of the following is a good reason to get the joints checked over:
- Fire-rated sealant that has cracked or shrunk back
- Snag lists that include open service penetrations
- Service penetrations left open after M&E works
- Hidden openings found during inspections
On a site such as Lanham Business Park, 1 mile west of Perry Green, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.
Before you book anyone
- Their public liability cover
- Will RAMS and insurance details be available?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How long is the guarantee, and what does it include?
What sets the cost
Your fixed quote is built from the real scope. It takes account of:
- Whether old sealant has to be cut out first
- Induction, permit and paperwork requirements
- How much there is to seal
- Joint width, depth and condition
What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote once you have the details.
Before you send an enquiry
The more we know, the firmer the quote. When you get in touch, include:
- The site address and postcode
- What the building is and how it’s used
- Any dates the work must fit around
- Clear photographs of the problem areas
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, speak to us on 01277 525 020 or email us.
