What we can’t put right
Honesty saves time and money. New sealant won’t cure:
- Fire risk assessments, a job for a competent assessor
- Gaps in walls that were never built as compartment walls
- Designing or specifying fire stopping, which sits with the designer or fire engineer
Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we will tell you honestly before you book.
Surfaces we seal
- Pipe penetrations
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Service gaps in risers
- Joints between fire-resisting walls and floors
Fire stopping in Durley
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Other openings need collars, wraps, batts, pillows or boards. If the detail calls for something other than sealant, we say so rather than force sealant into it. We work on small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and linear gaps at wall heads, and what we are called in for most is fire stopping installed outside its tested range and head-of-wall gaps with no fire seal. One point of contact handles commercial sealant work in Durley from the first photos to the final walk-round, whether it’s one building or several.
For a smaller site near Durley, we plan to do all the penetrations in one go, with the specification and photographs sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or use the quote form and we will arrange a return visit.

Common questions from Durley clients
Is a smaller place like Durley outside your area?
No. Places such as Durley are covered as much as the big towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
What happens to BS 476 references for fire stopping in Durley?
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. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Does weather matter for sealant work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
Can you handle several sites?
Yes. A group of buildings can go on one quote, with one point of contact.
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 inspection is the best way to catch problems early.
Signs you need fire stopping in Durley
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps. The tested detail for a linear joint states the width and movement it covers.
Any of the following is a good reason to get the joints checked over:
- Service penetrations left open after M&E works
- Fire seals cut back for extra cables and never reinstated
- Fire-rated sealant that has cracked or shrunk back
- Penetration schedules that need working through
On estates like Deer Park Farm Industrial Estate, which lies north-west of Durley, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.
Questions to ask before you book
- Do they follow the manufacturer’s priming guidance?
- Are they CHAS accredited or on Constructionline?
- Will RAMS and insurance details be available?
- The terms of the workmanship guarantee
Why act early in Durley
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down, and the right detail can be checked at the time. Older rural buildings around Durley move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

What sets the cost
These are the things that shape the price:
- Quantities, in metres or numbers
- Removal of failed or old sealant
- Backing rod, priming and other preparation
- How accessible the joints are
A quote for service penetrations depends on how many there are, their condition and the access. Call for a quote.
What we need to price the job
To price the job accurately, we need to understand the site. Useful things to include:
- The site address and postcode
- Any specification or named product
- The asbestos register, for older buildings
- Your programme or deadline
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.
Fire stopping in Durley: the local picture
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. We install whatever has been specified, to the product’s tested detail. Central London is about 63 miles from Durley. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product.
For a building such as Church of the Holy Cross, new heating or data runs are the usual reason penetrations need sealing. For a unit at a centre such as Bradbeers Retail park, which lies south-west of Durley, penetration seals are worth checking after each shop fit.
Durley is about 3 miles north-east of Hedge End, in Hampshire.

On site: what to expect
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For work around Durley, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.
- We read the specification, drawings or penetration schedule you send.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Getting the site ready
- Point out parking and an unloading spot
- Tell us what induction or permit system the site runs
- Clear stock, furniture or equipment away from the joints

Advice
How the job changes by surface
Plastic pipes
Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail, 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.
Drylining partitions
Drylined fire walls are tested in a particular build-up. The sealant detail has to be tested in that wall type, with the stated board layers before sealing.
