Fire rated sealant for Lee-over-Sands homes and businesses

DIY sealant or a professional job?

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.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Fire rated sealant in Lee-over-Sands

Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. We cut out the wrong material and the gap is resealed with a product tested for that use. We work on pipe & cable gaps, flats & HMOs and service penetrations, and the jobs we see most are unsealed gaps where pipes and cables go through a wall and standard silicone or caulk in a fire-stopping gap.

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

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What affects the cost of fire rated sealant

Every job gets its own quote. These are the things that affect it:

  • The number of rooms or windows
  • Which sealant suits the joint
  • How much old sealant there is and how hard it is to remove
  • How easy the joints are to reach

We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote.

Helping us quote

  • If it’s domestic, commercial or a hotel
  • Where the property is
  • Any previous sealing or DIY work
  • How we’d reach the joints

Need a quote? Please phone 0345 464 0079 or send us an email with a few details. You will know what we plan to do, and what it will cost, before any work begins.

What we are called out for in Lee-over-Sands

Gaps also open up as buildings move: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.

Any of these means the joints need attention:

  • Gaps flagged on a fire risk assessment
  • Cracked or shrunken fire-rated sealant
  • Open gaps behind door architraves
  • Fire stopping disturbed by later work

Letting a property close to Clacton-On-Sea station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

What your quote should include

  • What preparation is included
  • How long to leave it before use
  • How the colour is chosen
  • Whether they seal over old material or remove it

What fire rated sealant looks like in Lee-over-Sands

For seaside hotels, guest houses and holiday lets around Lee-over-Sands, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.

Around Lee-over-Sands, as everywhere, fire rated sealant is only as good as the preparation behind it.

Leave it or put it right?

Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, so we follow the maker’s details on every gap. In a small place like Lee-over-Sands, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Do you carry out fire risk assessments?

What information do you need?

Tell us what needs doing and where, with pictures by email if possible. If we need more, we’ll ask.

Will the old sealant be removed?

Yes. All of the old material is cut out and the joint cleaned before applying anything new.

Should I try DIY first?

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.

Can you give us a record of the work?

Yes. We note each location and the product that went in so it’s there for the next inspection.

The process

There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes from a few hours to a few days, depending on the number of gaps and the access in most cases. For a village or hamlet like Lee-over-Sands, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  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. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. Finally, we list where we worked and what we used, for your records.

Preparing for the visit

  • Mention if the joints have been sealed before
  • Let us know about parking restrictions
  • Let us know about stairs, lifts or work at height
