How we handle fire stopping in Chenies
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 won’t pretend otherwise. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. We work on small duct penetrations where the tested detail allows, cable penetrations and linear gaps at wall heads, and the usual reasons a site gets in touch are open linear gaps along the top of fire-resisting walls and builders’ foam or ordinary silicone in compartment walls. Searching for sealant specialists in Chenies? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
For a smaller site near Chenies, we plan to do all the penetrations in one go, with the specification and photographs sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
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.

When to bring in a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Questions we are asked in Chenies
Is a smaller place like Chenies outside your area?
No. Places such as Chenies are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Could you schedule work at a campus like Buckinghamshire New University for the vacation?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
How do we ask for a quote?
You can use the quote form on this site; alternatively, call the office on 01277 525 020 or email the details over. Include photos or drawings if you have them.
Will you come and look before quoting?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.
Do you take on small jobs?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Will fire-rated sealant work on every penetration?
No. It depends on the tested detail for that wall or floor and service. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards, and we’ll tell you when that applies.
Honest limits
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Deciding what a wall or floor needs, which belongs to the designer
- Issuing fire ratings or certificates for seals
- Plastic pipes whose detail calls for a collar or wrap
If in doubt, give us a call on 01277 525 020 or email drawings and photos and we will say what we think.
Surfaces we seal
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
- Pipe penetrations
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Cable penetrations
What happens if it’s left?
The longer openings stay, the more there tend to be: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable, rather than turning into a full building survey and reseal. Converted and older buildings near places like Chenies tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.

Fire stopping around Chenies: points for this area
At about 22 miles from central London, Chenies 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. A 2-mile radius around Chenies takes in several hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.
Tenant changes at parks like Boughton Business Park (1.9 miles west of Chenies) bring new data and services, and openings through fire-resisting walls need the specified seal. Older community buildings such as Church of St Michael that have been rewired or given new heating can have service gaps through walls worth checking against the specification. For a school such as Chenies School, penetration sealing fits best at the end of the summer works.

Surface by surface
Risers and ceiling voids
Voids hide a lot of unsealed openings. We follow your schedule area by area, and note anything we find that isn’t on it.
Small ducts
Some fire-rated sealant details cover small ducts. Larger or fire-rated ductwork usually needs a different solution set by the designer and we flag that rather than guess.
