Fire stopping across Lymore

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

Why it’s worth doing now in Lymore

Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. Halls, stores and units around places like Lymore may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

How we handle fire stopping in Lymore

It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control. What we bring is careful installation of the specified sealant, to the maker’s guidance. If you have unsealed penetrations discovered above suspended ceilings and fire-rated sealant that has cracked or shrunk back, we can put it right. Whoever orders the work in Lymore, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

A job near Lymore is normally planned around one visit, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

On site: what to expect

Tell us your site hours and access windows and we will plan around them. 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 Lymore need work, visits can be combined. A fixed quote is given before anything starts.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  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

  • Let building users know which areas are affected
  • Move anything stored against the joints
  • Confirm the product named in the specification

Owners, agents and contractors

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

Doing it in-house

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Penetration seals near Lymore

Lymore 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. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail. A number of hotels sit less than 2 miles from Lymore. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product.

Holiday works at schools like Milford-on-Sea Church of England Primary School often leave service openings to seal before pupils return. In a building such as Church of All Saints, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Lymore is about 2 miles south-west of Lymington, in Hampshire. Commercial clients in Lymore use us for work on service penetrations. Lymore is one of 723 places we cover in Hampshire for service penetrations. For work in that direction, see our Southampton page (15 miles or so).

Maintenance after handover

A few simple habits keep the new joints working:

  • Treat an open penetration as a priority repair
  • File the specified details where the next contractor can find them
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Check risers and ceiling voids after each round of works

After the work, brief anyone else working in the area that the openings are now sealed. If a seal has to be opened for a new service, it should be reinstated to the same detail, by someone who knows the system.

The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there, not months later.

Questions about Lymore

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

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 Lymore too far out for you?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Can you fit around our working hours?

Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

Do you take on small jobs?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and we will price the work to it.

Signs you need fire stopping in Lymore

When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.

Typical triggers for a call:

  • Old intumescent sealant that has split away
  • Seals disturbed by maintenance and left open
  • Fire stopping installed outside its tested range
  • Service penetrations left open after M&E works

Wherever services are added at a hospital such as Lymington New Forest Hospital, 2.9 miles north-east of Lymore, the compartment line has to be made good with the specified product.

Questions to ask before you book

  • The named product and why it was chosen
  • Will CSCS-carded applicators be on site?
  • How the existing material will be dealt with
  • Do they follow the manufacturer’s priming guidance?
