Common problems we fix in Spanish Green

Mixing products or improvising a detail breaks the link with the test evidence. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are the usual culprits.

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

  • Snag lists that include open service penetrations
  • Fire seals cut back for extra cables and never reinstated
  • Improvised or mixed-product fire seals
  • Unsealed openings around new pipes and cables

Tenant changes at parks like Campbell Court Office Park, 1.6 miles west of Spanish Green, bring new data and services, and openings through fire-resisting walls need the specified seal.

Questions to ask before you book

  • Are they CHAS accredited or on Constructionline?
  • Will failed sealant be removed rather than covered?
  • Proof of insurance
  • Their plan for phasing and protecting the area

How to choose a sealant contractor

Fire stopping in Spanish Green, done properly

A fire-rated sealant is only one part of a tested system: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow. If you have unsealed penetrations discovered above suspended ceilings and damaged fire seals in risers and voids, we can help. One point of contact handles commercial sealant work in Spanish Green from the first photographs to the final walk-round, whether it’s one building or several.

Barn and farm-building conversions near places like Spanish Green often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Different surfaces, different methods

Masonry and concrete

Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point so we know it sits within the tested range.

Small ducts

We seal around ducts only within what the tested detail covers. Dampers and ductwork systems themselves are outside our work.

Fire-rated sealing for Spanish Green buildings

In England, Approved Document B covers fire stopping of 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. Central London is about 41 miles from Spanish Green. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.

Large healthcare estates like Basingstoke and North Hampshire Hospital, 5.4 miles south-west of Spanish Green, change their services often, so penetration seals are worth checking after M&E work. For a school such as Daneshill School, penetration sealing fits best at the end of the summer works.

Spanish Green is about 4 miles north-west of Hook, in Hampshire. If you’re looking for fire stopping in Spanish Green, we can help. Across Hampshire, 723 places are covered, Spanish Green among them. Reading is covered too, around 9 miles from Spanish Green.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Issuing fire ratings or certificates for seals
  • Fire doors, dampers or other fire safety equipment

If you’re not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

Where we work in Spanish Green

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

Maintenance after handover

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Include service cupboards in routine inspections
  • Ask the designer to confirm details early on refits
  • Get seals inspected before ceilings and boxing close
  • Brief every trade that openings they make must be sealed

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

Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job compared with dozens found at once.

Leave it or put it right?

Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach. Halls, stores and units around places like Spanish Green may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

How a job runs

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. If others near Spanish Green need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

How long does a typical visit take?

The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.

What does an EI 60 rating mean?

The tests are BS EN 1366-3 for penetrations and BS EN 1366-4 for linear joints, and classification is to BS EN 13501-2. An EI 60 seal kept its integrity and insulation for 60 minutes as tested and the installation has to match the test.

Are you insured?

Yes. We are fully insured, and the certificate can go with your quote.

Do you seal openings left by new services?

Yes, where there is a specification for those walls and floors. Openings left by new services are among the most common jobs we see.

How do you choose the sealant?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
