Fire rated sealant for Southend-on-Sea homes and businesses

Why deal with it now?

An open gap in a fire-resisting wall is a route for smoke and fire. A proper seal lets the wall do its job again, and the work involved is often modest. In a busy place like Southend-on-Sea, a failed joint in a flat or office can send water into the space below, where it’s often found late and is bigger to put right.

What you pay reflects the work, not a rough estimate. That is why we ask about the job first.

Fire rated sealant in Southend-on-Sea, done properly

We do not assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. Our part is applying the specified sealant carefully, to the right depth and with the right backing. Common call-outs are for open joints along the top of partitions and open gaps behind door architraves, across door frames, service penetrations and pipe & cable gaps.

Hotels and other accommodation in Southend-on-Sea need sealant work done around guests. Work can be planned room by room, and out of hours where needed.

We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

What we’re called out for in Southend-on-Sea

A lot of fire stopping is out of sight: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.

The problems people generally mention when they call include:

  • Gaps where walls meet ceilings or slabs
  • Gaps around pipes and cables through fire-resisting walls
  • Gaps filled with a product that isn’t fire-rated
  • Door frames with gaps between frame and wall

Rented homes near Prittlewell station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Questions to ask before booking

  • What the cure time is
  • Are they insured?
  • How the surfaces are prepared before sealing
  • Is the old sealant removed completely?

Choosing a sealant specialist

What we do, step by step

Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes from a few hours to a few days, depending on the number of gaps and the access. Jobs in a place the size of Southend-on-Sea range from town-centre flats to offices and family homes. Whichever it is, tell us how to get in, where to park and where the work is.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. Anything that isn’t fit for the job comes out, and the gap is cleaned.
  3. We put in whatever backing or fill the product detail specifies.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. We record the locations and products used for your records.

Getting ready for the visit

  • Clear the area around the work

DIY versus a professional finish

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

Fire rated sealant around Southend-on-Sea

For seaside hotels, guest houses and holiday lets around Southend-on-Sea, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.

Managing a site like Westborough Academy? Then service openings in fire-resisting walls need checking after any refurbishment. Community buildings like Church of St Mary are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

How long does fire rated sealant take?

Most jobs take anything from a few hours to several days, depending on how many gaps there are. We will confirm how long when we quote.

How to look after the new joints

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Flag any open gap you spot round a pipe or cable
  • Check whether a sealant can be painted before decorating over it
  • Make resealing part of every contractor’s brief
  • Plan fire stopping into any work that goes through walls or floors

Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. A lot of damaged fire stopping comes from later work.

Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole.

How we quote for fire rated sealant

We quote each job individually. These are the things that affect it:
