How we handle fire stopping in Wellhouse

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. We work on service gaps in risers, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors, and the failures we’re asked to look at most are expanding foam used as fire stopping and open linear gaps along the top of fire-resisting walls. A single leaking joint is often how a building in Wellhouse 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.

For a smaller site near Wellhouse, we plan to do all the penetrations in one go, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Building owners, agents and FMs in Wellhouse

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Wellhouse can sit alongside others in a wider programme.

Quoting for work in Wellhouse

These are the things that shape the price:

  • The site’s rules and procedures
  • Backing rod, priming and other preparation
  • Phasing around occupants
  • How accessible the joints are

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Sending details for a quote

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

  • Photos of the joints, close up and from further back
  • Whether the building will be occupied during the work
  • Rough lengths or quantities, or drawings if you have them
  • The site address and postcode

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or use the quote form.

Why deal with it now?

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. Around Wellhouse, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we will quote for the lot.

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Why appoint us

  • Fixed quotes based on photographs, drawings or a visit
  • Over 20 years of commercial sealing
  • Fully insured
  • CSCS-carded applicators

How a job runs

Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and move on in phases so staff and visitors can carry on around us. For work around Wellhouse, we aim to finish in one 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. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

What we need from you

  • Move anything stored against the joints
  • Let us know about inductions and permits
  • Tell us which areas need to stay in use

Looking after the joints

Regular inspection catches problems early. In particular:

  • Put resealing into every M&E and fit-out package
  • Settle who seals which penetrations at the start of a project
  • Have penetrations checked while they can still be seen
  • Keep product data and details in the fire safety file

Don’t patch a fire-rated seal with anything outside its tested detail. A repair should use the original product, installed the same way, or a new specification from the designer.

Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small compared with dozens found at once.

Fire stopping around Wellhouse: what changes locally

At about 50 miles from central London, Wellhouse is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product. Fire stopping of openings and penetrations in England falls under Approved Document B. 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. What we install is set by the specification, and it goes in to the tested detail.

For a school such as Hermitage Primary School, penetration sealing fits best at the end of the summer works. For a unit at a site such as Red Shute Hill Industrial Estate, which lies west of Wellhouse, new power or data runs between office and warehouse can breach a compartment wall. Halls and meeting rooms at places like Church of St Mary sometimes gain new services, and any compartment wall crossed needs the specified seal.

Wellhouse is about 3 miles north of Thatcham, in West Berkshire. Our applicators travel to Wellhouse for work on service penetrations. Wellhouse is one of 140 places in West Berkshire on our list. Sites around Reading have their own page, roughly 12 miles from Wellhouse.

Surface by surface

Drylining partitions

Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range, and the detail may call for board patching or another product.

Linear joints

Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement.

Questions we are asked in Wellhouse

Is hospital work, at somewhere like West Berkshire Community Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

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

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes 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.

How soon can the area be used again?

We will confirm how long the chosen product needs to cure.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

How do I request a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.

Can you quote from photos?

It depends on the job. Simple work can often be priced from photographs, and bigger or more complex jobs usually get a visit.
