How a job runs
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. For a building around Crockerhill, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.
- We read the specification, drawings or penetration schedule you send.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
Getting the site ready
- Send any specification or drawings in advance
- Make sure the joints can be reached
- Send your site hours and access windows

How we handle fire stopping in Crockerhill
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal, not a rule of thumb. We work on pipe penetrations, linear gaps at wall heads and cable penetrations, and the failures we’re asked to look at most are fire seals cut back for extra cables and never reinstated and fire stopping installed outside its tested range. For commercial sealant work in Crockerhill, you deal with one contact from quote to sign-off, whether it’s one building or several.
Barn and farm-building conversions near places like Crockerhill often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Different surfaces, different methods
Metal pipes
Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on and we confirm each before sealing.
Risers and ceiling voids
Openings above suspended ceilings are easy to miss. We work through the areas on your schedule methodically.
Honest limits
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:
- Writing the fire-stopping specification
- Openings that need collars, wraps, batts or boards rather than sealant
- Walls or floors that aren’t fire-resisting to begin with
If you’re not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.
Surfaces we seal
- Cable penetrations
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Service gaps in risers
- Pipe penetrations
Quoting for work in Crockerhill
Your fixed quote is built from the real scope. It takes account of:
- How much there is to seal
- Any access equipment needed
- Which sealant the job calls for
- Phasing around occupants
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
What to include in your enquiry
It doesn’t need to be a full survey. A few details are enough to get going:
- Approximate linear metres or a joint schedule
- The site address and postcode
- A wide shot and a close-up of the area
- The asbestos register, for older buildings
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
Crockerhill: questions and answers
What happens to BS 476 references for fire stopping in Crockerhill?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes 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.
Does your area include sites such as Knowle Village Business Park, near Crockerhill?
Yes. Estates, retail parks and business parks around Crockerhill, Knowle Village Business Park among them, are all within reach. Photos and a short description are enough for a first look.
Will your applicators have CSCS cards?
Yes. We use CSCS-carded applicators.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Will you just go over the old sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Why act early in Crockerhill
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. Putting it right is normally a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. For buildings around smaller places like Crockerhill, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Why us?
- Public liability insurance in place
- A Constructionline member, so easy to vet
- Work to your specification and the manufacturer’s guidance
- Health and safety: CHAS accredited

Fire-rated sealing for Crockerhill buildings
For England, the fire stopping of penetrations is dealt with in Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. There are several hotels within about 2 miles of Crockerhill. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.
Tenant changes at parks like Knowle Village Business Park, 1.2 miles west of Crockerhill, bring new data and services, and openings through fire-resisting walls need the specified seal. Hotels such as The Old House Hotel (to the north of Crockerhill) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. For a unit at a centre such as Broadcut Retail Park (1.7 miles south of Crockerhill), penetration seals are worth checking after each shop fit.

Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Check risers and ceiling voids after each round of works
- Put resealing into every M&E and fit-out package
- Check with the data sheet before painting over fire sealant
- Have penetrations checked while they can still be seen
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, so check the product data first.
Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.
