Fire stopping for businesses in Lawrence Hill

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

How we handle fire stopping in Lawrence Hill

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, ring 01277 525 020 or email us with the schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. If you are dealing with service penetrations left open after M&E works and snag lists that include open service penetrations, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Lawrence Hill, preparation and product choice get the time they need.

In places the size of Lawrence Hill, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.

Work we carry out in Bracknell Forest comes with a 12-month guarantee. Should something we installed fail, ring 01277 525 020 or email the details over and we will come back to it.

Diagnose, treat, sign off

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work usually takes anything from one day to a planned run of visits, depending on the number of seals and the access. If neighbouring businesses or buildings around Lawrence Hill need work too, visits can be combined. Mention the building’s opening times and we will work within them.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  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. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Tell staff and tenants when we will be in
  • Share the asbestos register for older buildings

Owners, agents and contractors

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

How the quote is worked out

Quotes vary with the job. It mainly depends on:

  • How accessible the joints are
  • Travel to remote or island sites
  • Whether the work must be split into stages
  • Removal of failed or old sealant

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Details that help us quote

However big the job, these details speed things up:

  • When you need the work done
  • Drawings or a marked-up plan, if available
  • What the building is and how it’s used
  • Where the site is, with the postcode

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Aftercare for building managers

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

  • Include service cupboards in routine inspections
  • Check with the data sheet before painting over fire sealant
  • Don’t let anyone top up a fire seal with the wrong product
  • Make fire stopping part of every scope that crosses a fire-resisting wall

Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.

On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and the work runs in step with the M&E.

Your questions answered

Do you seal service penetrations in hotels around Lawrence Hill?

Yes. We install fire-rated and intumescent sealant where it is specified. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.

Can you work at a site such as Bracknell Enterprise Centre, by Lawrence Hill?

Yes, sites like Bracknell Enterprise Centre are within our area, along with the rest of Lawrence Hill. Photos and a short description are enough for a first look.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

What will the job cost?

There isn’t a price list, as every site differs. With photos or drawings, we can give you a fixed quote.

What about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

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

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Are you CHAS accredited?

Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Service penetrations in Lawrence Hill buildings

The planned town of Bracknell is on Lawrence Hill’s doorstep. Older buildings in planned towns have often been re-serviced several times, so penetrations left behind should be sealed with the specified product. Lawrence Hill lies roughly 28 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls; the gaps need the specified seal.

At a college such as Newbold College of Higher Education, which lies west of Lawrence Hill, checking penetration seals after summer M&E works is good practice. On a site such as Bracknell Enterprise Centre, 1.3 miles south-west of Lawrence Hill, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product. Campus buildings at universities such as Imperial College Silwood Park Campus, 4.3 miles to the east of Lawrence Hill, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.

Lawrence Hill is about 1 mile north of Bracknell, in Bracknell Forest. Anywhere in RG42, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Our Bracknell Forest coverage takes in 48 places, from busy centres to rural villages. For work in that direction, see our Reading page, about 10 miles away.

Work on service penetrations is covered throughout RG42 and RG12, for business premises of every kind. Among the streets we cover are Atte Lane, Quelm Lane and Sandy Lane. Sites close to Lawrence Hill are covered too, including Newell Green (1 mile north-west), Quelm Park (1 mile west), Wick Hill (1 mile south), Whitegrove (1 mile south-east) and Warfield (1 mile north). Further afield, our area takes in Sandhurst (6 miles south), Hanworth (3 miles south), College Town (6 miles south), Little Sandhurst (6 miles south-west), Birch Hill (3 miles south) and Owlsmoor (5 miles south). Lawrence Hill is one of the busier places in Bracknell Forest, and we take on service penetrations for its commercial and public buildings.

What the job involves on each surface

Drylining partitions

Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do, and the detail may call for board patching or another product.

Small ducts

Some fire-rated sealant details cover small ducts. Larger or fire-rated ductwork normally needs a different solution set by the designer, and we’ll say if that applies.

When it isn’t the sealant

Being straight saves everyone time. Fresh joints won’t solve:

  • Approving the work on behalf of building control
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Construction that lacks the fire resistance the seal relies on

Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we will tell you honestly.

Surfaces we seal

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