Fire rated sealant near Charlwood

Fire rated sealant in Charlwood, done properly

Fire stopping only performs as intended if it’s done to the detail: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over, one gap at a time. Common call-outs are for open holes round services passing through fire walls and gaps filled with a product that isn’t fire-rated, on flats & HMOs, door frames and linear gaps.

For holiday lets, converted business premises or a community building near Charlwood, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

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

Fire rated sealant in Charlwood: 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 work to the specification you’re given, installing the product to its tested details. There are hotels and other places to stay in and around Charlwood. Hotel work can be planned room by room, with out-of-hours working where needed.

Community buildings like Church of St Nicholas 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 Ifield station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

How the job changes by surface

Flats and HMOs

Flats and HMOs rely on fire separation between homes and the common parts. We work through the gaps on your assessment.

Door frames

Our work is the joint between frame and wall. The door leaf, its seals and closer need a door specialist, and we will say if we spot a problem with them.

Work for landlords, hotels and businesses

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.

In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.

How we quote for fire rated sealant

Your quote is based on your job. We look at:

  • Whether the work is at height
  • The number of rooms or windows
  • The number and length of the joints
  • Working hours on commercial sites

The cost depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.

What to tell us for a quote

There’s no need for technical detail. It helps if you can tell us:

  • The problem you’ve noticed
  • How many joints, rooms or windows are involved
  • Any access issues, like height or stairs
  • If it’s domestic, commercial or a hotel

Asking for a quote is easy: tell us what needs doing and where. Photos by email help us understand the job, and we will take it from there.

Common problems we fix in Charlwood

Much fire stopping is hidden: above ceilings, inside risers and behind panels. Out of view, damage sits unnoticed until someone inspects.

Common reasons people contact us include:

  • Old fire sealant that has split or come away
  • Open gaps behind door architraves
  • Joints picked up in a fire-stopping survey
  • Gaps left after a refit or conversion

Managing a site like Charlwood Village Primary School? Then fire-stopping around service openings should be restored whenever new services go in.

Common questions in Charlwood

I let a flat near Ifield station. Can you help?

Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.

Do you work in hotels near Charlwood?

Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.

Can I add another job to the visit?

Yes. Just list everything you need and we will quote it together.

Is the work guaranteed?

Yes. Every job comes with our 12-month guarantee.

Is it messy?

Not at all. We work neatly, protect the area around the joints and tidy up afterwards.

Do the sealants smell?

That depends on the sealant. Some smell for a while, some hardly at all.

Do you remove the old sealant?

Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.

Where do you work from?

Our base is in Crawley, and we work across South East England, London and Scotland.

How the visit works

Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere as small as Charlwood, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. We measure every gap and note what it’s in and what passes through.
  3. Unsuitable material such as ordinary foam or silicone is cut out.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. Every location is recorded with the product used.

Preparing for the visit

  • Tell us about any previous sealing or DIY attempts
  • Mention any parking rules near the property
  • Keep pets and children clear of the area while we work

Advice

Why deal with it now?

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. Older cottages and farmhouses around Charlwood can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.

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 call for the right materials, safe access and experience.

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.
