Looking after it afterwards

So the new joints stay in good condition:

  • Allow for resealing whenever new services are run
  • Check whether a sealant can be painted before decorating over it
  • Tell trades working in the building that fire seals must be put back
  • Flag any open gap you spot round a pipe or cable

Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint.

Open gaps do not only matter in a fire: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.

How we handle fire rated sealant in Little Waltham

A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That’s the part we focus on. We work on service penetrations, pipe & cable gaps and flats & HMOs, and people most often call us about gaps where walls meet ceilings or slabs and holes left by a change of layout.

Work in a small place like Little Waltham is planned ahead, journey included, so it can be fitted around guests, clients or events where possible.

The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

What we do, step by step

When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Little Waltham, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. Finally, we list where we worked and what we used, for your records.

Getting ready for the visit

  • On commercial sites, let us know about site rules
  • Plan for the work area to be out of bounds to pets and children
  • Where the joints are inside, avoid wetting them before we arrive

What we are called out for in Little Waltham

Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. We see plenty of fire stopping that was hurried particularly when it was the last job before handover.

It’s worth asking for a quote if you see:

  • Gaps left after a refit or conversion
  • Gaps where walls meet ceilings or slabs
  • Standard silicone or caulk in a fire-stopping gap
  • Gaps flagged on a fire risk assessment

Schools such as Chelmer Valley High School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

  • How long to leave it before use

10 questions to ask before you book

Fire rated sealant in Little Waltham: local notes

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Community buildings like Little Waltham United Reformed Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there. If you let a flat or house near Beaulieu Park station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

When it is not the sealant

We’d rather tell you now than do work that won’t last, so these are the limits:

  • Construction that doesn’t provide fire resistance on its own
  • Assessing a building’s fire safety
  • Sign-off of the building, which sits with building control or your assessor

If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.

Surface by surface

Flats and HMOs

Plasterboard walls

In plasterboard walls, the condition of the board edge matters. Crumbling edges are cleaned back before the sealant goes in.
