Questions we’re asked in Fishbourne

Is Fishbourne off your patch?

No. Small places get the same service as large ones. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

What happens to BS 476 references for fire stopping in Fishbourne?

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

What will the job cost?

Each job is quoted on its own details. To get one, call the office on 01277 525 020 or email us.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Is it fine to apply new sealant on top of old?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Can you fit around our working hours?

Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

When can the area be used after sealing?

We will confirm how long the chosen product needs to cure.

Fire stopping in Fishbourne

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate and we’d rather say that up front. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. The enquiries we see most involve hidden openings found during inspections and head-of-wall gaps with no fire seal, across linear gaps at wall heads, service gaps in risers and small duct penetrations where the tested detail allows. Facilities teams, main contractors and managing agents in Fishbourne tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around smaller places like Fishbourne, many commercial buildings are conversions or extensions of older ones, so it’s worth confirming the wall or floor type before choosing the seal. We match the product to the substrate and service, and say so if a collar, wrap or batt is the specified item.

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.

What we’re called out for in Fishbourne

Physical damage is another reason seals stop doing their job. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe.

Clients usually get in touch after noticing one or more of the following:

  • Builders’ foam or ordinary silicone in compartment walls
  • Unsealed openings around new pipes and cables
  • Fire stopping installed outside its tested range
  • Damaged fire seals in risers and voids

Workshops and IT rooms at colleges like Chichester College, 1 mile to the east of Fishbourne, are re-serviced often, leaving penetrations to seal.

Before you book anyone

  • Do they follow the manufacturer’s priming guidance?
  • The terms of the workmanship guarantee
  • How joint depth will be controlled
  • Their public liability cover

Questions to ask before you appoint anyone

What we can’t put right

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Fire risk assessments, a job for a competent assessor
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Large openings beyond what any sealant detail covers

If you’re not sure, just call 01277 525 020 or send details through our quote form and we will give you a straight answer.

What we seal

  • Small duct penetrations where the tested detail allows
  • Service gaps in risers
  • Cable penetrations
  • Joints between fire-resisting walls and floors
  • Pipe penetrations
  • Linear gaps at wall heads

Owners, agents and contractors

Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Fishbourne can form part of a wider programme across West Sussex.

Our process

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. What matters most for a job in Fishbourne is a clear list of what needs doing. A fixed quote follows.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. Completed areas are checked with you, with the records agreed when we quoted.

What we need from you

  • Share the asbestos register for older buildings
  • Move anything stored against the joints
  • Tell us which areas need to stay in use

Getting a fixed quote

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call 01277 525 020 or email a schedule or drawings.

What the job involves on each surface

Metal pipes

Copper and steel pipes are a common service penetration for fire-rated sealant. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on and we confirm each before sealing.

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We follow your schedule area by area and tell you about openings outside the list.

Maintenance after handover

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Keep product data and details in the fire safety file
  • Keep general-purpose fillers away from compartment walls
  • Have penetrations checked while they can still be seen
  • Settle who seals which penetrations at the start of a project

Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original, or a new specification from the designer.

Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small.

Penetration seals near Fishbourne

The area within 2 miles of Fishbourne holds plenty of hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. The 2 miles around Fishbourne include three care or nursing homes. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product.

At a university such as University of Chichester, which lies east of Fishbourne, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. For a unit at a site such as Terminus Industrial Estate, 0.8 miles east of Fishbourne, new power or data runs between office and warehouse can breach a compartment wall.

Fishbourne is about 1 mile west of Chichester, in West Sussex. We send applicators to Fishbourne for service penetrations, handled exactly as we handle every other area. Fishbourne is one of 373 places we cover in West Sussex. There’s a separate page for Portsmouth, about 12 miles away.
