Owners, agents and contractors
We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Jockey End can sit alongside others in a wider programme across Hertfordshire.
Fire stopping in Jockey End
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, give us a call on 01277 525 020 or send details through our quote form with the schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we will confirm with the quote. If you are dealing with service penetrations left open after M&E works and builders’ foam or ordinary silicone in compartment walls, we can put it right, whatever the surface. Most enquiries from Jockey End start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Smaller places such as Jockey End still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
A 12-month guarantee applies to all our work. Should something we installed fail, call 01277 525 020 or use the quote form and we’ll come back to it.

If in doubt, call 01277 525 020 or send photos by email and we’ll say what we think.

Fire stopping in Jockey End: the local picture
Jockey End is about 28 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. In England, Approved Document B covers fire stopping of openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
For a school such as Gaddesden Row JMI School, penetration sealing fits best at the end of the summer works. Hospital estates such as Hemel Hempstead Hospital (4.4 miles south of Jockey End) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
Jockey End is about 4 miles north of Hemel Hempstead, in Hertfordshire. Any commercial site in Jockey End is covered. We work across 371 places in Hertfordshire, large and small. For work in that direction, see our London page, about 28 miles away.

Why it’s worth doing now in Jockey End
Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme which is why earlier is better. Halls, stores and units around places like Jockey End may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.

Questions we are asked in Jockey End
Is hospital work, at somewhere like Hemel Hempstead Hospital, something you do?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Is Jockey End too small for you to travel to?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Do you guarantee your work?
Yes. Our workmanship is backed for 12 months.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Can you work to our specification?
Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.
Keeping the joints sound
A few simple habits keep the new joints working:
- Treat an open penetration as a priority repair
- Leave fire sealant to cure fully before covering it
- Look above ceilings when tiles are lifted for other jobs
- Agree the fire-stopping specification before services go in
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted, and the data sheet says which.
Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.
Different surfaces, different methods
Plastic pipes
Plastic waste pipes through slabs come up often. Whether sealant alone is acceptable depends entirely on the tested detail.
Risers and ceiling voids
Openings above suspended ceilings are easy to miss. We follow your schedule area by area, and note anything we find that isn’t on it.
Diagnose, treat, sign off
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next. For a building around Jockey End, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- First we go through the drawings, schedule or specification for the seals.
- 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.
- 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.
Preparing the site
- Confirm the product named in the specification
- Make sure the joints can be reached
- Flag any permit to work we’ll need
