Questions we’re asked in Stanford Common

What happens to BS 476 references for fire stopping in Stanford Common?

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Is a hospital such as Cygnet Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

When can you be on site?

Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

Are you insured?

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

How do we ask for a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

Can the building stay open while you work?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

What will the job cost?

Every job gets its own fixed quote. For yours, speak to us on 01277 525 020 or send details through our quote form.

Fire stopping for commercial buildings in Stanford Common

The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints and the results are classified to BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. If you’re dealing with seals disturbed by maintenance and left open and unsealed penetrations discovered above suspended ceilings, we can help, whatever the surface. For commercial sealant work in Stanford Common, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Smaller places such as Stanford Common still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Compartments and services around Stanford Common

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. The area within 2 miles of Stanford Common holds a number of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.

Hotels such as Asperion Hillside Hotel (to the east of Stanford Common) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. At a university such as University of Surrey, 2.9 miles to the south-east of Stanford Common, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

Stanford Common is about 4 miles north-west of Guildford, in Surrey. Our applicators travel to Stanford Common for work on service penetrations. Our Surrey coverage takes in 379 places. Reading is covered too, some 18 miles away.

Anyone looking for fire stopping in GU24 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee.

If your building is just outside Stanford Common, we cover Pirbright (1 mile north), Worplesdon (1 mile east), Willey Green (2 miles south), Fairlands (2 miles south-east) and Normandy (2 miles south-west). Bigger towns within reach include Guildford (4 miles south-east), Woking (4 miles north-east), Camberley (5 miles north-west), Farnham (8 miles south-west), Egham (11 miles north) and Walton-on-Thames (12 miles north-east).

What happens if it’s left?

The longer openings stay, the more there tend to be: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable and avoids a much larger catch-up later. One visit to deal with every failing joint makes more sense than several trips to a place like Stanford Common, rather than one at a time. Send photos of each area and we will quote for the lot.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Site staff or a sealant specialist?

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

From enquiry to sign-off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Stanford Common need work, visits can be combined. You’ll have a fixed quote before work starts.

  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. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  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. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

What we need from you

  • Send any specification or drawings in advance
  • Share your working hours and any access restrictions
  • Point out parking and an unloading spot

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to ring 01277 525 020 or email drawings and photos with what you know.

Related advice

Do you need fire stopping in Stanford Common?

Openings in fire-resisting walls usually 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.

Common reasons buildings call us in:

  • Head-of-wall gaps with no fire seal
  • Service penetrations left open after M&E works
  • Improvised or mixed-product fire seals
  • Non-fire-rated filler around services

For a site team at a college like Merrist Wood College, 1.1 miles south-east of Stanford Common, fire-rated sealing is best scheduled after the summer works.

Comparing quotes

  • Will CSCS-carded applicators be on site?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Their plan for phasing and protecting the area
  • Is the sealant right for the movement and the substrate?

How to choose a sealant contractor

What sealant work can’t fix

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

  • Openings that need collars, wraps, batts or boards rather than sealant
  • Walls or floors that aren’t fire-resisting to begin with
  • Issuing fire ratings or certificates for seals

If you are not sure, just speak to us on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

What we seal

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