Fire stopping in Hastingwood

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

On site: what to expect

Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Smaller jobs around Hastingwood can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. The specification and schedule come first, so we know which details apply.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out first.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Before we start on site

  • Point out any areas we must not close
  • Point out parking and an unloading spot
  • Move anything stored against the joints

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

Advice

Fire stopping in Hastingwood, done properly

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, often unnoticed. Those on your schedule are closed with the specified product. The enquiries we see most involve open linear gaps along the top of fire-resisting walls and seals that don’t match their tested detail, on small duct penetrations where the tested detail allows, service gaps in risers and pipe penetrations. Facilities teams, main contractors and managing agents in Hastingwood 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 Hastingwood, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

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.

After the work

Cleaning and maintenance staff play a part too. Share these points with them:

  • Foam or ordinary sealant is never a fire-seal repair
  • File the specified details where the next contractor can find them
  • Report damaged or disturbed seals as soon as they’re spotted
  • Make fire stopping part of every scope that crosses a fire-resisting wall

During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown and get them dealt with.

Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small compared with dozens found at once.

FAQs: Hastingwood

Do you take on work at healthcare sites like Princess Alexandra Hospital?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Is Hastingwood too small for you to travel to?

No. Places such as Hastingwood are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

How long does a typical visit take?

That varies with the scale of the job, but the work typically takes a single visit for a short list of penetrations, or a phased programme for a whole building. For bigger or phased jobs, we’ll set out a timescale with the quote.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

How do you choose the sealant?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Fire-rated sealing for Hastingwood buildings

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. Either way, we install the specified product to its tested detail. Hastingwood is about 20 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.

Offices at parks like Hastingwood Business Centre, less than half a mile north-east of Hastingwood, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. Halls and meeting rooms at places like Church of St Mary Magdalene sometimes gain new services, and any compartment wall crossed needs the specified seal.

Hastingwood is about 2 miles south-east of Harlow, in Essex. Businesses, contractors and managing agents in Hastingwood use us for work on service penetrations. We work across 644 places in Essex, from busy centres to rural villages. Our London page has more on work in that area, about 20 miles away.

When to call us in Hastingwood

Plenty of openings were simply never closed because they sat out of sight above a ceiling or inside a riser. They come to light during inspections, refits or when another trade lifts a tile.

If one of these sounds familiar, it’s time for a closer look:

  • Non-fire-rated filler around services
  • Damaged fire seals in risers and voids
  • Penetration schedules that need working through
  • Fire-rated sealant that has cracked or shrunk back

Wherever services are added at a hospital such as Princess Alexandra Hospital (to the north-west of Hastingwood) the compartment line has to be made good with the specified product.

What to look for in a quote

  • Will CSCS-carded applicators be on site?
  • What site paperwork they can supply
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Their pre-qualification and accreditations

Questions to ask before you appoint anyone

Honest limits

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Large openings beyond what any sealant detail covers
  • Deciding what a wall or floor needs, which belongs to the designer
  • Construction that lacks the fire resistance the seal relies on

If you are not sure, just speak to us on 01277 525 020 or email drawings and photos and we will give you a straight answer.

What we seal

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

How the quote is worked out

A fixed quote reflects the actual work. It allows for:

  • Quantities, in metres or numbers
  • Backing rod, priming and other preparation
  • Travel to remote or island sites
  • Induction, permit and paperwork requirements

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.

Before you send an enquiry

For an accurate fixed quote, we need a clear picture of the site. Useful things to include:

  • Photos of the joints, close up and from further back
  • Approximate linear metres or a joint schedule
  • Any dates the work must fit around
  • Where the site is, with the postcode

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Why it’s worth doing now in Hastingwood

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach and each detail can be checked as we go. Halls, stores and units around places like Hastingwood may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.
