How we handle fire rated sealant in Segensworth

We don’t assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. What we do is apply the right product to that specification, properly and neatly. Typical jobs include unsealed gaps where pipes and cables go through a wall and joints picked up in a fire-stopping survey, across flats & HMOs, door frames and pipe & cable gaps.

Somewhere as small as Segensworth, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.

Every job is covered by our 12-month guarantee.

Your questions about fire rated sealant in Segensworth

Do you work for hotels and guest houses in Segensworth?

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.

Do you cover smaller places like Segensworth?

Do I have to be there?

It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.

Can I add another job to the visit?

Can I choose the sealant colour?

Will we have a record of what was sealed?

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

Fire rated sealant in Segensworth: local notes

For seaside hotels, guest houses and holiday lets around Segensworth, 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 are given, installing the product to its tested details.

If you let a flat or house near Swanwick station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. For buildings such as St John, service openings in its walls need the right fire-rated sealant, as in any building.

Should I try it myself first?

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

What happens if it’s left?

Squirting in whichever sealant is nearest doesn’t make a fire seal. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. In a small place like Segensworth, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

Take a look at what affects the cost or customer reviews.

What affects the quote in Segensworth

The price is agreed before any work begins. It takes into account:

  • Mould in or behind the old joints
  • The size of the job
  • How easy the joints are to reach
  • The type of sealant required

Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we’ll explain what it covers.

What to tell us for a quote

When you call or email, it’s useful to know:

  • Roughly how big the job is
  • The address or postcode of the job
  • How we’d reach the joints
  • If someone has resealed it before

We quote each job on its own, so the first step is telling us about yours. Simply ring 0345 464 0079 or drop us an email and describe the job and send pictures if you have them.

What we can’t put right

Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant won’t put right:

  • Issuing a fire rating or certificate for a building
  • Problems with the door itself rather than the gap around the frame
  • A wall that isn’t a fire-resisting element to begin with

If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.

What we seal

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

Landlord and commercial work in Segensworth

We work for landlords and agents as well as homeowners. Sealant work between tenants keeps a property looking cared for.

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.

What happens on the day

We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a handful of gaps, and longer for a whole building. In a small place like Segensworth, access is normally the main thing to plan. 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. Locations and products are written up and any gaps unsuitable for sealant are flagged.

How to prepare

  • For business premises, tell us about site rules or sign-in
  • Clear items away from the joints we’re working on
  • Mention any tricky access

How to get a quote

Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand, and we’ll come back to you with a quote.

When to call us in Segensworth

Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.

If you can see any of these, it’s time to have the joints looked at:

  • Fire seals that have cracked with movement
  • Gaps left after a refit or conversion
  • Open joints along the top of partitions
  • Sealant items on a fire risk assessment action list

Managing a site like Cornerstone CofE (VA) Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

Questions to ask before booking
