Fire stopping across Cross Lane

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

About our fire stopping in Cross Lane

We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on sites in Cross Lane. If you’re dealing with penetration schedules that need working through and seals that don’t match their tested detail, we can help. One point of contact handles commercial sealant work in Cross Lane from the first photos to the final walk-round, for single jobs and planned programmes alike.

Buildings in a smaller place such as Cross Lane that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Leave it or put it right?

Fire stopping is a regular point raised at inspections and handover. Late discoveries can delay handover while openings are reopened and resealed which is why earlier is better. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.

A quote for service penetrations depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.

What sets the cost

We price every job individually. The things that drive the figure:

  • Site requirements such as inductions and permits
  • Any access equipment needed
  • Phasing around occupants
  • How much there is to seal

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

What to include in your enquiry

The more we know, the firmer the quote. When you get in touch, include:

  • Asbestos survey details if the building is older
  • Whether the building will be occupied during the work
  • Anything awkward about access or site hours
  • The site address and postcode

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Compartment walls and floors in Cross Lane

For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. Either way, we install the specified product to its tested detail. The area within 2 miles of Cross Lane holds several hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.

Workshops and IT rooms at colleges like HTP Apprenticeship College, 0.6 miles to the west of Cross Lane, are re-serviced often, leaving penetrations to seal. Refits at places like Wakes Retail Park (under half a mile west of Cross Lane) often reroute services through walls between units.

Cross Lane is about 1 mile north-east of Newport, in the Isle of Wight. Businesses, contractors and managing agents in Cross Lane use us for work on service penetrations. 125 places across the Isle of Wight fall within our area, Cross Lane among them. Our Portsmouth page has more on work in that area, about 12 miles away.

Postcode districts covered here: PO30, PO31 and PO41 for service penetrations. Among the streets we cover are Ash Road, Chain Lane and Beech Road. We also cover Barton (1 mile south), Fairlee (1 mile north), Staplers (1 mile south-east), Hillgrove (1 mile north-east) and Whippingham (3 miles north). Bigger towns within reach include Ryde (5 miles east), Cowes (4 miles north), Sandown (6 miles south-east), Shanklin (7 miles south-east), Ventnor (8 miles south-east) and East Cowes (3 miles north). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so give the site location in your enquiry.

Landmarks near Cross Lane

Around Cross Lane, our work takes us to commercial buildings near Bargeman's Rest pub, Island Innovation VI Form Campus and Seaclose Park and the streets around them.

How a job runs

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before we move to the next. For a site in Cross Lane, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. We start with your penetration schedule, drawings or specification.
  2. Access, permits and the order of areas are agreed with the site team.
  3. We compare every service penetration with its tested detail before sealing.
  4. Unsuitable material is removed and the opening cleaned first.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. Anything outside the detail is reported to you rather than sealed.

What we need from you

  • Share the asbestos register for older buildings
  • Send any specification or drawings in advance
  • Arrange parking or a loading space

Owners, agents and contractors

When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Honest limits

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

  • Plastic pipes whose detail calls for a collar or wrap
  • Writing the fire-stopping specification
  • Fire doors, dampers or other fire safety equipment

If you’re not sure, just call the office on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

Where we work in Cross Lane

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

Questions about Cross Lane

Can you seal penetrations in a hotel in Cross Lane after a refit?

Yes. We install fire-rated and intumescent sealant where it is specified. We match the product to the wall or floor and the services, and say if something other than sealant is needed.

Will you work in a care home in Cross Lane 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.

How long before the joints can be used?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Do you offer coloured sealant?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.

How do I request a quote?

You can use the quote form on this site; alternatively, call 01277 525 020 or email drawings and photos. Include photos or drawings if you have them.

What we are called out for in Cross Lane

Openings in fire-resisting walls typically appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.

Things that usually lead to an enquiry:

  • Fire sealant pulled out of the opening
  • Unsealed penetrations discovered above suspended ceilings
  • Fire stopping installed outside its tested range
  • Snag lists that include open service penetrations

For a building such as St Paul's Church, new heating or data runs are the usual reason penetrations need sealing.

Questions to ask before you book

  • Will RAMS and insurance details be available?
  • Their public liability cover
  • How long is the guarantee, and what does it include?
  • Will CSCS-carded applicators be on site?
