Common questions from Lordington clients

Can you work at a site such as Hambrook Business Park, by Lordington?

Yes. Estates, retail parks and business parks around Lordington, Hambrook Business Park among them, are all within reach. Photos and a short description are enough for a first look.

How does the move away from BS 476 affect penetration seals in Lordington?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Can you work while the building is occupied?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Will you just go over the old sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

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 you quote from photographs?

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

Is your workmanship covered by a guarantee?

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

Fire stopping in Lordington, 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 service gaps in risers, pipe penetrations and joints between fire-resisting walls and floors, and the usual reasons a site gets in touch are openings left by services added after handover and seals that don’t match their tested detail. Searching for sealant specialists in Lordington? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

Barn and farm-building conversions near places like Lordington often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

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.

When to bring in a specialist

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

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, which is what makes a joint last.

What the job involves on each surface

Small ducts

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

Drylining partitions

Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range.

Work for main contractors and building owners

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Lordington can form part of a wider programme across West Sussex.

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

Honest limits

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Openings that need collars, wraps, batts or boards rather than sealant
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Reviewing a building’s overall fire safety

If you are not sure, just call the office on 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.

Where we work in Lordington

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

Our process

When we get to site, 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 anything is cut or cleaned, with the work itself typically taking a single visit for a short list of penetrations, or a phased programme for a whole building. For a building around Lordington, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out first.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. Anything outside the detail is reported to you rather than sealed.

What we need from you

  • Warn occupants and staff about the work
  • Make sure the joints can be reached
  • Point out any areas we must not close

What affects the price in Lordington

We price every job individually. The things that drive the figure:

  • Working within restricted access windows
  • The site’s rules and procedures
  • Access and working height
  • The size and state of each joint

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

Sending details for a quote

The more we know, the firmer the quote. Helpful details to send:

  • Rough lengths or quantities, or drawings if you have them
  • The type of building and who uses it
  • Specification clauses that apply
  • Access details, including height

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to call the office on 01277 525 020 or send photos by email.

Compartment walls and floors in Lordington

For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Lordington lies roughly 55 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.

For a building such as Racton Church, new heating or data runs are the usual reason penetrations need sealing. Office fit-outs on sites such as Hambrook Business Park, 1.4 miles to the south of Lordington, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. Wherever services are added at a hospital such as Spire Hospital Portsmouth (3 miles west of Lordington) the compartment line has to be made good with the specified product.
