Fire stopping for Eastrop sites

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

After the work

Keep the joints in good shape with a few simple steps:

  • Arrange inspection before areas are covered up
  • Keep general-purpose fillers away from compartment walls
  • Ask which product is in place before decorating
  • Treat an open penetration as a priority repair

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted.

Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there, not months later.

How we handle fire stopping in Eastrop

A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in. We work on joints between fire-resisting walls and floors, small duct penetrations where the tested detail allows and pipe penetrations, and the usual reasons a site gets in touch are fire stopping installed outside its tested range and unsealed penetrations discovered above suspended ceilings. A single leaking joint is often how a building in Eastrop first comes to us: we look at the rest while we’re there and tell you what we find.

Around Eastrop, penetration and linear seals tend to be one-building jobs. With the specification and photos of the gaps, we can give a fixed quote and bring the right products.

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.

Fire-rated sealing for Eastrop buildings

Eastrop is about 46 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. Plenty of hotels sit less than 2 miles from Eastrop. In hotels, bedroom and corridor walls are typically fire-resisting, so services added in a refit need sealing with the specified product.

For a unit at a site such as Daneshill East Industrial Estate (1 mile north-east of Eastrop), new power or data runs between office and warehouse can breach a compartment wall. For a hotel such as Great Western Hotel, which lies north-west of Eastrop, penetration seals are worth checking after any refit or services upgrade. At a college such as Basingstoke College of Technology (0.6 miles west of Eastrop), checking penetration seals after summer M&E works is good practice.

Eastrop is about 1 mile east of Basingstoke, in Hampshire. Eastrop sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Hampshire coverage takes in 723 places, large and small. We also cover Reading, around 13 miles from Eastrop.

Cost factors for service penetrations

Your fixed quote is built from the real scope. It allows for:

  • Backing rod, priming and other preparation
  • How much existing material needs removing
  • Access and working height
  • How much there is to seal

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Details that help us quote

Good information means a firmer quote. When you get in touch, include:

  • The site address and postcode
  • A wide shot and a close-up of the area
  • Any specification or named product
  • Approximate linear metres or a joint schedule

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

Doing it in-house

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

How a job runs

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Several jobs near Eastrop can be grouped on one trip. Mention the building’s opening times and we’ll work within them.

  1. We read the specification, drawings or penetration schedule you send.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. Mineral wool or other backing goes in wherever the detail asks.
  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.

Getting the site ready

  • Let us know about inductions and permits
  • Share your working hours and any access restrictions
  • Arrange parking or a loading space

Related advice

Leave it or put it right?

The longer openings stay, the more there tend to be: each new service adds to the list. A schedule that is dealt with regularly stays manageable. In a smaller place such as Eastrop, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Questions about Eastrop

Do you work in occupied care homes around Eastrop?

Yes. We work around residents’ routines, a room or two at a time. Any site rules, from signing in to infection control, are agreed before we start.

Is Eastrop off your patch?

No. Places such as Eastrop are covered as much as the big towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

What will the job cost?

It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we’ll price it properly.

What do BS EN 1366-3 and BS EN 13501-2 mean?

Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Classification follows BS EN 13501-2, where E is integrity, I is insulation and the number is minutes, as in EI 60. That rating only holds when the product is installed to its tested detail.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also speak to us on 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.
