Rowlands Castle: your questions answered

Do you cover smaller places like Rowlands Castle?

Yes. Rowlands Castle is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Can you do fire rated sealant in Rowlands Castle?

Yes, Rowlands Castle 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 tell us what needs doing, and we’ll give you a clear quote.

Will we have a record of what was sealed?

Yes. Locations and products are written up when we finish. If you need pictures or a set layout, ask when you get a quote.

Can you quote for more than one area?

Of course. Combining jobs makes good use of the visit.

Do you offer different sealant colours?

In most cases you can choose. We’ll tell you which colours the right product comes in.

Do you hold any approvals?

Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.

Can I use normal mastic around a pipe through a fire wall?

No. Ordinary silicone, caulk or foam isn’t tested as fire stopping. We cut it out and reseal with a fire-rated product.

Can new sealant go over the old?

No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.

How we handle fire rated sealant in Rowlands Castle

Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. Common call-outs are for unsealed gaps where pipes and cables go through a wall and gaps left after a refit or conversion, on service penetrations, door frames and pipe & cable gaps.

In a smaller place like Rowlands Castle, commercial jobs tend to be smaller buildings: a pub, a surgery, a school, a shop or a few business units. Each needs the same care with its sealant as any larger building.

We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Landlord and commercial work in Rowlands Castle

Letting agents often deal with us directly. Tell us the address, the job and how access works.

We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured for the work.

What we do, step by step

We work through the job in order: 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 and we leave things clean and tidy. Parking around Rowlands Castle is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Anything that is not fit for the job comes out, and the gap is cleaned.
  3. Where the tested detail needs backing or fill, we fit it.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. Locations and products are noted so you have them on file.

Getting ready for the visit

  • Try not to wet indoor joints just before the visit
  • On commercial sites, let us know about site rules
  • Mention any leaks or damp you’ve noticed

Keeping the joints in good condition

So the new joints stay in good condition:

  • Flag any open gap you spot round a pipe or cable
  • Store the list of sealed gaps with your building paperwork
  • Never patch a fire seal with standard sealant
  • Don’t paint over fire sealant until it has cured

Avoid covering a sealed gap with anything that is not part of the tested detail. If it needs repair, use the same type of product. Ask us if you’re not sure which product was used.

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

What we cannot put right

New sealant can’t fix everything, and we’d rather say so up front. It will not solve:

  • Walls or floors that weren’t built to resist fire
  • Sign-off of the building, which sits with building control or your assessor
  • Big openings where sealant alone is not the tested solution

Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly before booking.

Where we work in Rowlands Castle

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

What we’re called out for in Rowlands Castle

Door frames are a common weak spot. The architrave hides the gap between frame and wall, so it’s easy to leave unsealed when doors are changed.

People usually contact us after spotting something like this:

  • Seals cut through by electricians, plumbers or data installers
  • Holes left by a change of layout
  • Gaps around pipes and cables through fire-resisting walls
  • Unsealed gaps around fire door frames

Managing a site like Havant Academy? Then service openings in fire-resisting walls need checking after any refurbishment.

Questions to ask before you book

  • How long to leave it before use
  • What product goes in the joint
  • What insurance they hold
  • How long the guarantee is

Choosing a sealant specialist

Fire rated sealant in Rowlands Castle: local notes

If you run a hotel, guest house or holiday let in a coastal place like Rowlands Castle, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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 work to the specification you’re given, installing the product to its tested details.

For buildings such as The Church on the Green, older buildings that have had new heating or wiring often have service gaps worth checking. For landlords with property near Rowlands Castle station, any gap left by new services in shared walls should be closed with a fire-rated product.

Different surfaces, different methods

Service penetrations

Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. The sealant is chosen for what passes through and how wide the gap is.

Masonry and concrete

Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it before the sealant goes in.
