About our fire stopping in Midhurst

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, and they are easy to forget. Those on your schedule are closed with the specified product. We work on pipe penetrations, linear gaps at wall heads and small duct penetrations where the tested detail allows, and what we are called in for most is hidden openings found during inspections and open linear gaps along the top of fire-resisting walls. Looking for mastic applicators who cover Midhurst? We’ve been sealing commercial buildings since 2005.

Around smaller places like Midhurst, many commercial buildings are conversions or extensions of older ones, so it’s worth confirming the wall or floor type before choosing the seal. The right product depends on the wall or floor and the services passing through, and we will tell you if the detail calls for something other than sealant.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What the job involves on each surface

Risers and ceiling voids

Service risers and the voids above ceilings are where openings collect. Access to these areas is planned with you in advance along with any permits your site needs.

Small ducts

Ducts are only sealed with sealant where the detail allows it. Dampers and ductwork systems themselves are outside our work.

Why deal with it now?

Fire stopping is a regular point raised at inspections and handover. Late discoveries can delay handover while openings are reopened and resealed. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.

The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Why us?

  • Old sealant cut out, never sealed over
  • Specification-led, product-correct work
  • One contact handling all your sites
  • CHAS accredited

Fire stopping in Midhurst: the local picture

Several hotels sit less than 2 miles from Midhurst. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. Midhurst is about 45 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.

Large healthcare estates like Midhurst Community Hospital (0.8 miles north-east of Midhurst) change their services often, so penetration seals are worth checking after M&E work. In a hotel such as The Spread Eagle Hotel (less than half a mile north-east of Midhurst), new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. Halls and meeting rooms at places like Roman Catholic Church of Divine Motherhood sometimes gain new services, and any compartment wall crossed needs the specified seal.

Midhurst is about 8 miles east of Petersfield, in West Sussex. Any commercial site in Midhurst is covered, for single jobs and planned programmes alike. Across West Sussex, 373 places are covered, including Midhurst. Sites around Portsmouth have their own page, roughly 19 miles from Midhurst.

Work on service penetrations is covered throughout GU29, for business premises of every kind. If your site is on Station Road, Edinburgh Square and Pretoria Avenue or close by, send details and we will quote for service penetrations. Access to Midhurst is via the A272 and A286. Sites close to Midhurst are covered too, including Bepton Common (1 mile south-west), West Lavington (1 mile east), Cocking Causeway (1 mile south), Easebourne (1 mile north-east) and Woolbeding (1 mile north-west). Further afield, our area takes in Bognor Regis (14 miles south), Chichester (10 miles south), Littlehampton (15 miles south-east), Storrington (14 miles east), Billingshurst (13 miles east) and Portfield (10 miles south).

Building owners, agents and FMs in Midhurst

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

What affects the price in Midhurst

What shapes the price:

  • Any access equipment needed
  • How much there is to seal
  • Which sealant the job calls for
  • Induction, permit and paperwork requirements

The price depends on the quantity of joints, what has to come out first and the access. Call for a quote when you are ready.

Sending details for a quote

We can often quote from photos and a few details. Please tell us:

  • Drawings or a marked-up plan, if available
  • When you need the work done
  • The asbestos register, for older buildings
  • Where the site is, with the postcode

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, ring 01277 525 020 or send details through our quote form.

Diagnose, treat, sign off

On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself normally taking a single visit for a short list of penetrations, or a phased programme for a whole building. Several jobs near Midhurst 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. We fit the backing the detail asks for, to the stated depth.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  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

  • Explain the parking and delivery arrangements
  • Send any specification or drawings in advance
  • Point out any areas we must not close

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Doing it in-house

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.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

Common questions from Midhurst clients

Do you seal service penetrations in hotels around Midhurst?

Yes, to the specification and the product’s tested detail. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.

Is a smaller place like Midhurst outside your area?

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

Can the sealant be colour-matched?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

Can you work while the building is occupied?

In most cases, yes. Phased work can be planned so areas stay in use.

Who decides which product is used?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Do you guarantee your work?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

Can weather delay the job?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
