What sealant work can’t fix

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:

  • Deciding what a wall or floor needs, which belongs to the designer
  • Fire risk assessments, a job for a competent assessor
  • Openings that need collars, wraps, batts or boards rather than sealant

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

Surfaces we seal

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

Quoting for work in Blue Bell Hill

Quotes vary with the job. It mainly depends on:

  • Backing rod, priming and other preparation
  • Distance, for remote addresses
  • How much there is to seal
  • The product specified

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Details that help us quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • Photos of the joints, close up and from further back
  • The site address and postcode
  • When you need the work done
  • Drawings or a marked-up plan, if available

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to call 01277 525 020 or send details through our quote form.

On site: what to expect

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. If others near Blue Bell Hill need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

What we need from you

  • Explain the parking and delivery arrangements
  • Let building users know which areas are affected
  • Have the specification and drawings to hand

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.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Where services cross fire walls in Blue Bell Hill

Blue Bell Hill has several hotels close by, all within 2 miles. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product. 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.

Large healthcare estates like Spire Alexandra Hospital (to the east of Blue Bell Hill) change their services often, so penetration seals are worth checking after M&E work. Campus buildings at universities such as University for the Creative Arts - Rochester (3.3 miles north of Blue Bell Hill) see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. For a unit at a site such as Lower Bell Industrial Estate, 0.8 miles south of Blue Bell Hill, new power or data runs between office and warehouse can breach a compartment wall.

Blue Bell Hill is about 2 miles south-west of Chatham, in Kent. Across the ME5 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.

Why it’s worth doing now in Blue Bell Hill

An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail. Converted and older buildings near places like Blue Bell Hill tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote when you’re ready.

What happens to BS 476 references for fire stopping in Blue Bell Hill?

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.

Do you work in Blue Bell Hill?

Yes. Blue Bell Hill is in our area, within our coverage of Greater London, South East England and Scotland. To discuss a job, speak to us on 01277 525 020 or email us.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Can staff carry on working while you are here?

In the majority of cases, yes. Phased work can be planned so areas stay in use.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Do you need to see the site first?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

Looking after the joints

Regular inspection catches problems early. Specifically:

  • Flag new cables with no seal around them
  • Have penetrations checked while they can still be seen
  • Check with the data sheet before painting over fire sealant
  • Agree the fire-stopping specification before services go in

New services after handover are a common way fire stopping gets breached. A short check at the end of each job saves a long hunt later.

The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open instead of being left for someone else.
