Fire rated sealant for Hatfield Heath homes and businesses

Fire rated sealant in Hatfield Heath

Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate, with a record of the products and locations if you need one. If you are dealing with old fire sealant that has split or come away and unsealed gaps around fire door frames, we can help.

For holiday lets, converted business premises or a community building near Hatfield Heath, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or email us.

Workplaces and buildings in Hatfield Heath

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.

For site and facilities teams at buildings such as Hatfield Heath Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. If you look after a church, hall or community building such as Holy Trinity Church, older buildings that have had new heating or wiring often have service gaps worth checking.

Is it messy?

No. The area is protected while we work and cleaned up afterwards.

Do I need to be at home?

We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.

Quotes for fire rated sealant in Hatfield Heath

Call for a quick quote. What matters most is:

  • How easy the joints are to reach
  • How much old sealant there is and how hard it is to remove
  • How much there is to do
  • Any mould that needs treating

Doing several joints on one visit generally makes better use of the time than several visits. We’ll give you a clear quote for the lot.

Helping us quote

Before you ask for a quote, have a think about:

  • If someone has resealed it before
  • Pictures of the joints, sent by email
  • Roughly how big the job is
  • Whether it’s a home or a business

What happens on the day

Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours for a handful of gaps, and longer for a whole building. In a small place like Hatfield Heath, access is generally the main thing to plan. 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. We remove any old or unsuitable filler and clean the gap.
  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. Locations and products are noted so you have them on file.

Preparing for the visit

  • Let us know if you’ve seen damp or leaks
  • Tell us about any previous sealing or DIY attempts
  • For indoor joints, keep the area dry beforehand if you can

Getting a quote

Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand, and we’ll take it from there.

Honest limits

To be straight with you, some problems need a different trade:

  • Assessing a building’s fire safety
  • Fire doors that need new seals, closers or hardware
  • A wall that isn’t a fire-resisting element to begin with

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

Where we work in Hatfield Heath

  • Service penetrations
  • Door frames
  • Linear gaps
  • Pipe & cable gaps
  • Flats & HMOs
  • Plasterboard & masonry

DIY versus a professional finish

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

A DIY attempt doesn’t rule out a professional job. We cut it out and start again.

Keeping the joints in good condition

To keep the joints looking good and working properly:

  • Check whether a sealant can be painted before decorating over it
  • Make resealing part of every contractor’s brief
  • Take pictures of fire stopping before ceilings or boxing go back
  • Check risers, ceiling voids and cupboards during building checks

Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some can’t, so ask us which we used.

An open gap isn’t only a fire issue: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.

Signs you need fire rated sealant in Hatfield Heath

If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it is not installed as tested. Rushed fire stopping is common, especially where it was squeezed in at the end of a project.

Keep an eye out for these signs:

  • Open holes round services passing through fire walls
  • Door frames with gaps between frame and wall
  • Standard silicone or caulk in a fire-stopping gap
  • Old fire sealant that has split or come away

Rented homes near Sawbridgeworth station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.

Our hiring checklist

Surface by surface

Service penetrations

New gaps tend to show up where services have been added. We clean out what’s there and reseal to the right depth with backing where the detail needs it.

Door frames

Behind most architraves is a gap between frame and wall. Where it’s open, we seal it to the product’s details for that gap size so the architrave can be refitted.
