When it isn’t the sealant
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Issuing fire ratings or certificates for seals
- Plastic pipes whose detail calls for a collar or wrap
- Deciding what a wall or floor needs, which belongs to the designer
If you are not sure, just phone 01277 525 020 or email the details over and we’ll give you a straight answer before you book.
Surfaces we seal
- Service gaps in risers
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Cable penetrations
- Pipe penetrations
Fire stopping in Crondall, done properly
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 service gaps in risers, pipe penetrations and cable penetrations, and what we are called in for most is unsealed penetrations discovered above suspended ceilings and snag lists that include open service penetrations. For commercial sealant work in Crondall, you deal with one contact from quote to sign-off, whether it’s one building or several.
Rural conversions around Crondall can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

When to bring in a specialist
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
What sets the cost
To price the job, we consider:
- Backing rod, priming and other preparation
- The site’s rules and procedures
- Whether the work must be split into stages
- The product specified
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.
What to include in your enquiry
Diagnosis starts before we arrive. Let us know:
- The postcode of the building
- Anything awkward about access or site hours
- Your programme or deadline
- Clear photographs of the problem areas
To get a fixed quote, call 01277 525 020 or send photos by email with the site address and an outline of the work. You can also send details through our quote form.
FAQs: Crondall
Is a hospital such as Spire Clare Park Hospital somewhere you can work?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Will you work in a care home in Crondall without moving residents out?
Yes. We agree rooms and times with the manager and work a few areas at a time. Noise and disruption are kept to a minimum.
Do you work in Scotland as well as England?
Our work covers Greater London, the South East and every Scottish council area. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook says service penetrations should keep at least the fire resistance of the wall or floor, using products tested for their end use.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Is Crondall in your area?
Yes. We cover Crondall, within our coverage of Greater London, South East England and Scotland. For a quote, call the office on 01277 525 020 or email a schedule or drawings.
What’s the quickest route to a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
Do you hold third-party fire-stopping installer certification?
No, and we won’t imply otherwise. Some clients require third-party installer schemes even though the law doesn’t. If it doesn’t require one, we can install the specified fire-rated sealant to its tested detail.
For managing agents and facilities managers
CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
Diagnose, treat, sign off
Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you. For a building around Crondall, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- 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.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Before we start on site
- Share the asbestos register for older buildings
- Make sure the joints can be reached
- Warn occupants and staff about the work

Where services cross fire walls in Crondall
Central London is about 38 miles from Crondall. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal. Two care or nursing homes sit less than 2 miles from Crondall. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail.
Schools such as Crondall Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. Offices at parks like Fleet Business Park (to the north-east of Crondall) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. For an estates team at a campus like University for the Creative Arts, 2.6 miles south-east of Crondall, summer M&E works are normally followed by a round of penetration sealing.

Surface by surface
Cables and cable bundles
Single cables and small bundles are often within a fire-rated sealant’s tested detail. The detail limits bundle size and the gaps between and around cables.
Linear joints
Joints at the top of partitions may need to move as the slab above deflects. The specified product and backing for that movement are what goes in.
