FAQs for Selsey

Is Selsey in your area for fire rated sealant?

Yes, Selsey is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we will send you a clear quote.

What’s the best way to get a price for fire rated sealant in Selsey?

Just ring 0345 464 0079 or send us an email and let us know what needs doing and where. We will give you a clear quote, with a fixed price before work begins.

Do you work in flats, HMOs and commercial buildings?

Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. We agree access and the order of work with you first.

Will there be a smell?

It depends on the product. Some products have a noticeable smell, others very little.

Should I try DIY first?

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.

Is standard sealant good enough for a fire gap?

No. Ordinary silicone, caulk or foam isn’t tested as fire stopping. If it’s been used, we remove it and use the right product.

What do you put in the joint?

Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we’re using and why.

Will the old sealant be removed?

Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.

About our fire rated sealant in Selsey

Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. We work on door frames, pipe & cable gaps and flats & HMOs, and people most often call us about open joints along the top of partitions and holes left by a change of layout.

For anyone managing a school, care home, pub or office in Selsey, washroom sealant, kitchen joints and fire-rated sealant around service openings all need upkeep. Work can be planned around opening hours where needed.

Big or small, it’s backed by our one-year guarantee in Selsey and across West Sussex.

What the job involves on each surface

Linear gaps

Long, narrow gaps appear where walls meet slabs and ceilings. We seal them to the tested detail, with backing where it’s needed.

Door frames

Our work is the joint between frame and wall. Doors, seals and closers are for a door specialist, and we’ll say if we spot a problem with them.

How it works

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes from a few hours to a few days, depending on the number of gaps and the access. For a job in Selsey, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.

  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. 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 records.

Before we arrive

  • Try not to wet indoor joints just before the visit
  • Mention any leaks or damp you’ve noticed
  • Mention any parking rules near the property

How to get a quote

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

Fire rated sealant around Selsey

If you run a hotel, guest house or holiday let in a coastal place like Selsey, 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. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

If you look after a building such as Seal Primary Academy, gaps opened by contractors for new cabling are a common finding in schools and offices.

Quotes for fire rated sealant in Selsey

We don’t publish a price list, because jobs vary so much. What we look at:

  • Mould in or behind the old joints
  • When we can work, for business premises
  • The size of the job
  • The product the joint needs

Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.

What we need to know

To make quoting easier, let us know:

  • Pictures of the joints, sent by email
  • How we’d reach the joints
  • Where the job is, and your postcode
  • Whether it’s a home or a business

Every job is quoted individually, so the first step is telling us about yours. Simply phone 0345 464 0079 or send us an email and describe the job.

What we can’t put right

Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:

  • Walls or floors that weren’t built to resist fire
  • Deciding what fire stopping a building needs
  • Sign-off of the building, which sits with building control or your assessor

If you are not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.

What we seal

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

Why it’s worth doing now in Selsey

Items left open on a fire risk assessment tend to come back at the next review. Having them sealed and recorded now gives you evidence that the item was dealt with. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and early is when they’re cheapest and quickest to sort.

The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and agree the price before starting.

Why us?

  • Over 20 years’ experience
  • We’re fully insured
  • Rated 4.9 stars on Google
  • 12-month guarantee on every job

What we are called out for in Selsey

A lot of fire stopping is out of sight: above ceilings, inside risers and behind panels. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.

Signs it’s time to call us include:

  • Open joints along the top of partitions
  • Joints picked up in a fire-stopping survey
  • Fire seals that have cracked with movement
  • Damaged fire sealant left by other trades

For buildings such as St Peter's Church, service openings in its walls need the right fire-rated sealant, as in any building.

Questions to ask before booking

  • How the surfaces are prepared before sealing
  • Who turns up on the day
  • What insurance they hold
  • What the cure time is

10 questions to ask before booking

Keeping the joints in good condition

Looking after new joints is easy, and it makes a real difference:

  • Tell trades working in the building that fire seals must be put back
  • Keep the record of products and locations with your fire safety documents
  • Ask which product was used before you paint
  • Take photos of fire stopping before ceilings or boxing go back

Any fire seal that’s cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.

It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the job gets bigger.
