Trusted fire rated sealant in Privett

Fire rated sealant in Privett

Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, with a record of the products and locations if you need one. We work on flats & HMOs, service penetrations and pipe & cable gaps, and common reasons people get in touch are new service routes left unsealed after building work and gaps around pipes and cables through fire-resisting walls.

Around a place like Privett, halls, schools and small businesses all have washrooms and kitchens used by many people. Sealant and fire-rated joints there matter as much as in any larger building.

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

Should I try it myself first?

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

How the visit works

All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. It normally takes from a few hours to a few days, depending on the number of gaps and the access. For a job in Privett, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. Each gap is measured and its substrate and service noted.
  3. Any non-fire-rated filler is removed and the faces cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. Every location is recorded with the product used for your files.

Getting ready for the visit

  • Let us know if you’ve seen damp or leaks
  • Clear items away from the joints we’re working on

Commercial buildings in Privett

If you run a hotel, guest house or holiday let in a coastal place like Privett, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. There are hotels and other places to stay in and around Privett. Hotel work can be planned room by room, with out-of-hours working where needed.

Schools such as Gomer Infant School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. Rented homes near Portsmouth Harbour station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. For buildings such as St Faith's Church, gaps around pipes and cables are worth checking after any building work there.

Keeping the joints in good condition

After the cure time, these simple habits help:

  • Ask every contractor to reseal any fire stopping they disturb
  • Get damaged fire seals looked at promptly
  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • Keep pictures of seals that will be hidden

Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some cannot.

An open gap is not only a fire issue: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.

FAQs for Privett

I let a flat near Portsmouth Harbour station. Can you help?

Yes. We work for letting agents and landlords as well as householders. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.

Will you come out to Privett?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

What does fire rated sealant cost?

It depends on the job, so we quote each one individually. To get one, ring 0345 464 0079 or drop us an email with a short description of the job.

Do you carry out fire risk assessments?

No. We follow the requirements from your assessor, designer or building control and install to the manufacturer’s details.

What should I tell you?

A short description and the location, with photos by email if possible. We will ask anything else we need to know.

Do you do fire sealant around door frames?

Yes. We seal the gap between the frame and the wall with a suitable fire-rated product following the tested details. The door, its seals and closer are for a door specialist.

Do you work in flats, HMOs and commercial buildings?

Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. The order of work and access are planned with you.

Is intumescent sealant the same as fire-rated sealant?

Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent types expand when heated, and they’re one of the options. The specification and the tested detail decide which is used.

Quotes for fire rated sealant in Privett

The price is agreed before any work begins. It’s based on:

  • The number and length of the joints
  • Access and height
  • Working hours on commercial sites
  • How much old sealant there is and how hard it is to remove

What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.

Asking for a quote

To make quoting easier, let us know:

  • Any previous sealing or DIY work
  • Access, such as stairs, a lift or height
  • Where the property is
  • Whether it’s a home or a business

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.

When it is not the sealant

New sealant can’t fix everything, and we will tell you before work begins. Sealant will not put right:

  • Doors that are not fire doors in the first place
  • Walls or floors that weren’t built to resist fire
  • Deciding what fire stopping a building needs

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

Joints and surfaces we work on

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

Different surfaces, different methods

Masonry and concrete

Core-drilled and broken-out holes in concrete are often irregular. We measure the gap at its widest point to make sure it suits the product.

Flats and HMOs

In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We work through the gaps on your assessment.

Why act early in Privett

Doing it once, properly, beats doing it twice. Work that does not follow the tested detail may have to come out again when the building is next checked. In a smaller place like Privett, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.

We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.
