What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship.

A job near Hook End is usually planned around one visit, with the specification and photographs sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

How a job runs
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Jobs in and around smaller places like Hook End are normally planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- We gun the sealant in to the specified depth around each service and tool it.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Getting the site ready
- Tell us what induction or permit system the site runs
- Explain the parking and delivery arrangements
- Point out any areas we must not close
Ask for a quote
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call 01277 525 020 or email a schedule or drawings.
Advice
What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Writing the fire-stopping specification
- Construction that lacks the fire resistance the seal relies on
- Issuing fire ratings or certificates for seals
If in doubt, give us a call on 01277 525 020 or use the quote form and we’ll say what we think before you book.
Surfaces we seal
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Service gaps in risers
- Cable penetrations
- Linear gaps at wall heads
Surface by surface
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers and the installation has to fit inside those limits.
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. Each gap is measured where it is widest so we know it sits within the tested range.
When to bring in a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Penetration seals near Hook End
Hook End lies roughly 40 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. Approved Document B is the English guidance that covers fire stopping around 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. Our part stays the same: the specified product, installed to its tested detail.
In a building such as St Peter and St Paul, any service penetration through a fire-resisting wall should be sealed to the specified detail. On a site such as Vanalloys Business Park, which lies north-east of Hook End, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product. For a school such as Checkendon Church of England (A) Primary School, penetration sealing fits best at the end of the summer works.

What sets the cost
Quotes vary with the job. Expect it to depend on:
- Joint width, depth and condition
- Whether the work must be split into stages
- The product specified
- How much existing material needs removing
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.
Details that help us quote
Good information means a firmer quote. Helpful details to send:
- The product your specification calls for
- What the building is and how it’s used
- The asbestos register, for older buildings
- Access details, including height
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
Questions we are asked in Hook End
Can you take on a job at a hospital such as Battle Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is Hook End too far out for you?
No. Small places get the same service as large ones. 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.
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.
Do you approve fire stopping for building control?
No. Approval sits with the designer, principal designer or building control. We’ll confirm the products and details used.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also phone 01277 525 020 or use the quote form. Include photos or drawings if you have them.
What does an EI 60 rating mean?
In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. An EI 60 seal kept its integrity and insulation for 60 minutes as tested.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
