Fire stopping near Old Alresford

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

Fire stopping in Old Alresford, done properly

On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we’ll confirm with the quote. We work on pipe penetrations, joints between fire-resisting walls and floors and cable penetrations, and what we are called in for most is seals that don’t match their tested detail and unsealed penetrations discovered above suspended ceilings. A specialist sealant contractor works differently from a general builder: in Old Alresford, that means joint design, primers and backing rod as standard.

Rural conversions around Old Alresford can put new fire-resisting partitions inside older structures. 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 we explain exactly what that covers when we quote.

Questions we’re asked in Old Alresford

Is Old Alresford too small for you to travel to?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Do you work on fire-rated sealing in hotels in Old Alresford?

Yes, to the specification and the product’s tested detail. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.

Do you seal on top of existing sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

What do you charge?

Every job gets its own fixed quote. To get one, phone 01277 525 020 or send photos by email with a description of the work.

Are you fully insured?

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

How long does a job like this take?

That varies with the scale of the job, but the work normally takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

What affects the price in Old Alresford

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • Specialist products, such as fire-rated or hygienic sealants
  • Phasing around occupants
  • Site requirements such as inductions and permits
  • Distance, for remote addresses

Access can matter as much as the joints themselves: 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.

What we need to price the job

Diagnosis starts before we arrive. Let us know:

  • Rough lengths or quantities, or drawings if you have them
  • Where the site is, with the postcode
  • Any dates the work must fit around
  • The product your specification calls for

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or call the office on 01277 525 020 or send photos by email to discuss it first.

On site: what to expect

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes a single visit for a short list of penetrations, or a phased programme for a whole building, and our waste is bagged and taken away as we go. Jobs in and around smaller places like Old Alresford are usually planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. Completed areas are checked with you, with the records agreed when we quoted.

What we need from you

  • Make sure the joints can be reached
  • Confirm the product named in the specification
  • Point out parking and an unloading spot

Request a quote

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.

Owners, agents and contractors

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Old Alresford can form part of a wider programme across Hampshire.

Honest limits

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

  • Deciding what a wall or floor needs, which belongs to the designer
  • Signing off or certifying a building’s fire stopping
  • Walls or floors that aren’t fire-resisting to begin with

If you are not sure, just ring 01277 525 020 or email us and we’ll give you a straight answer.

What we seal

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

Doing it in-house

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Leave it or put it right?

Open service penetrations matter on ordinary days, not just in a fire: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first. Around Old Alresford, it’s better to renew all the failing joints at once. Send photos of each area and we’ll quote for the lot.

A quote for service penetrations depends on how many there are, their condition and the access. Ask us for a fixed quote.

Fire stopping around Old Alresford: how the place shapes the job

Central London is about 54 miles from Old Alresford. 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. Approved Document B is the English guidance that covers fire stopping around 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.

For a building such as Church of St Mary, new heating or data runs are the usual reason penetrations need sealing. Schools such as Perins School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. In a hotel such as Bell Hotel, 0.9 miles south of Old Alresford, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.
