Trusted fire rated sealant in Broad Street

Fire rated sealant in Broad Street, done properly

We often work from an action list drawn up by a fire risk assessor. Send us the list or the survey and we will quote for the fire-rated sealant work on it. We’re often asked to deal with open holes round services passing through fire walls and cracked or shrunken fire-rated sealant, across flats & HMOs, linear gaps and door frames.

In a village or hamlet like Broad Street, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.

Our work is backed for twelve months.

Common problems we fix in Broad Street

Over time, buildings change layout and use. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.

The most common problems we see are:

  • Standard silicone or caulk in a fire-stopping gap
  • Cracked or shrunken fire-rated sealant
  • Fire stopping disturbed by later work
  • New service routes left unsealed after building work

Letting a property close to Hollingbourne station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

How to choose a mastic man

How it works

There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to several days, depending on how many gaps there are in most cases. Somewhere as small as Broad Street, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. We take out any damaged or unsuitable sealant.
  3. Gaps are cleaned of dust and loose material.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. We record what was done and flag anything that needs a different system.

Getting ready for the visit

  • Tell us about access, such as stairs, a lift or high-level joints
  • Plan for the work area to be out of bounds to pets and children
  • For indoor joints, keep the area dry beforehand if you can

How we quote for fire rated sealant

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • Any mould that needs treating
  • The product the joint needs
  • The old material and how stubborn it is
  • The number and length of the joints

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Helping us quote

To make quoting easier, let us know:

  • Whether it has been sealed before
  • The rough size of the job
  • Pictures of the joints, sent by email
  • Access, such as stairs, a lift or height

For a quote, ring 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. We will give you a clear quote before any work starts.

Keeping the joints in good condition

So the new joints stay in good condition:

  • Do not paint over fire sealant until it has cured
  • Keep photos of seals that will be hidden
  • Tell trades working in the building that fire seals must be put back
  • Don’t fill fire-stopping gaps with ordinary foam or silicone

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

When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.

Can I do it myself?

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

For landlords and businesses

Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.

Housing providers, facilities teams and property managers book us too in Broad Street and across Kent. We can quote a run of properties together, and we are fully insured for the work.

How the job changes by surface

Masonry and concrete

Holes through concrete and block are rarely neat. We check the gap size around the service to make sure it suits the product.

Flats and HMOs

Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified room by room.

Commercial buildings in Broad Street

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
