Fire stopping in Crowhurst, done properly
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. We use sealant where it is the specified product, and we tell you when a detail calls for something else. If you are dealing with builders’ foam or ordinary silicone in compartment walls and open linear gaps along the top of fire-resisting walls, we can help. A single leaking joint is often how a building in Crowhurst 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 Crowhurst is usually planned around one visit, 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 workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

After the work
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Flag new cables with no seal around them
- Agree the fire-stopping specification before services go in
- Look above ceilings when tiles are lifted for other jobs
- Leave fire sealant to cure fully before covering it
After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail, by someone who knows the system.
Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small compared with dozens found at once.
What sets the cost
A fixed quote reflects the actual work. It takes account of:
- Whether the work must be split into stages
- Removal of failed or old sealant
- Quantities, in metres or numbers
- Specialist products, such as fire-rated or hygienic sealants
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Before you send an enquiry
Good information means a firmer quote. Helpful details to send:
- The product your specification calls for
- The postcode of the building
- Any dates the work must fit around
- Whether an asbestos survey exists
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, phone 01277 525 020 or email us.
Fire stopping around Crowhurst: points for this area
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. What we install is set by the specification, and it goes in to the tested detail. At about 20 miles from central London, Crowhurst is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product.
Large healthcare estates like Foetal Alcohol Spectrum Disorders Clinic (to the north of Crowhurst) change their services often, so penetration seals are worth checking after M&E work. Halls and meeting rooms at places like Church of St George sometimes gain new services, and any compartment wall crossed needs the specified seal. Office fit-outs on sites such as Lambs's Business Park, 2.7 miles west of Crowhurst, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.

Why it’s worth doing now in Crowhurst
An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product, so it makes sense to get it right first time. Older rural buildings around Crowhurst move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
