Need fire stopping in North Baddesley?

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

When to bring in a specialist

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

How we handle fire stopping in North Baddesley

Facilities managers in North Baddesley often find open service penetrations when ceilings come down for other work. Where the walls and floors already have a fire-stopping specification, we can work to it, matching the product and detail it names. Where there isn’t one, the designer or fire engineer needs to set one first. Most enquiries involve fire sealant pulled out of the opening and improvised or mixed-product fire seals, on linear gaps at wall heads, joints between fire-resisting walls and floors and cable penetrations. A single leaking joint is often how a building in North Baddesley first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In places the size of North Baddesley, 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.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Compartment walls and floors in North Baddesley

At about 69 miles from central London, North Baddesley is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls, and the gaps need sealing with the specified product. North Baddesley has three care or nursing homes no more than 2 miles away. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail.

Residences at universities like University of Southampton (to the south-east of North Baddesley) have compartment walls that must be resealed whenever services change. For a building such as All Saints, new heating or data runs are the usual reason penetrations need sealing. Shop fits in centres such as Chestnut Avenue Retail Park, 2.7 miles east of North Baddesley, can bring new services through fire-resisting walls between units, which then need the specified seal.

North Baddesley is about 2 miles south-east of Romsey, in Hampshire. Commercial clients in North Baddesley use us for work on service penetrations, as part of our coverage of Hampshire. Our Hampshire coverage takes in 723 places, large and small.

Your questions answered

What does the BS 476 change mean for fire-rated sealant in North Baddesley?

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 North Baddesley too small for you to travel to?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Is your workmanship covered by a guarantee?

Yes. Workmanship is guaranteed for 12 months.

What will the job cost?

We don’t publish prices, because every site is different. With photos or drawings, we can give you a fixed quote.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

When can the area be used after sealing?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Are you CHAS accredited and on Constructionline?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

What we can’t put right

Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:

  • Plastic pipes whose detail calls for a collar or wrap
  • Fire doors, dampers or other fire safety equipment
  • Writing the fire-stopping specification

If in doubt, give us a call on 01277 525 020 or email the details over and we’ll say what we think before you book.

Joints and surfaces we work on

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

What the job involves on each surface

Cables and cable bundles

Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. The detail limits bundle size and the gaps between and around cables and we work within those limits.

Small ducts

Ducts are only sealed with sealant where the detail allows it. The ductwork, its supports and any dampers are for the ductwork contractor.

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. What matters most for a job in North Baddesley is a clear list of what needs doing. A fixed quote follows.

  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. 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

  • Share the asbestos register for older buildings
  • Tell staff and tenants when we’ll be in
  • Tell us which areas need to stay in use

Request a quote

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call 01277 525 020 or email us with what you know.

What sets the cost

These are the things that shape the price:

  • Distance, for remote addresses
  • Whether the work must be split into stages
  • Backing rod, priming and other preparation
  • Induction, permit and paperwork requirements

What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you’re ready.

What to include in your enquiry

A few photos plus some basic facts will normally do. It helps to include:

  • Whether an asbestos survey exists
  • Photos of the joints, close up and from further back
  • The type of building and who uses it
  • Your programme or deadline

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.
