Trusted fire rated sealant in Shalden

Fire rated sealant in Shalden, done properly

Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. Typical jobs include old fire sealant that has split or come away and unsealed gaps where pipes and cables go through a wall, on linear gaps, plasterboard & masonry and flats & HMOs.

In a village or hamlet like Shalden, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.

All our work is covered by a one-year guarantee, wherever you are in Hampshire.

Commercial buildings in Shalden

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Rented homes near Alton station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

When to call us in Shalden

In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It may look fine, but it isn’t a fire-rated seal.

Any of these means the joints need attention:

  • Door frames with gaps between frame and wall
  • Open joints along the top of partitions
  • Holes left by a change of layout
  • Sealant items on a fire risk assessment action list

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

Questions to ask before you book

  • Whether they seal over old material or remove it
  • How the colour is chosen
  • Whether they’re fully insured
  • How the surfaces are prepared before sealing

10 questions to ask before booking

How it works

All our tools and materials come with us in the van. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for a handful of gaps, and longer for a whole building. In a small place like Shalden, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. Before starting, we go through the specification or action list with you.
  2. Each gap is measured and its substrate and service noted.
  3. Any non-fire-rated filler is removed.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. We hand over a list of locations and products.

Before we arrive

  • Try not to wet indoor joints just before the visit
  • Let us know about earlier repairs to the joints
  • Let us know about parking restrictions

Advice

Landlords, agents and businesses in Shalden

Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

What sealant work can’t fix

Before booking, it’s worth knowing the limits too:

  • Large holes that need a different fire-stopping system
  • Walls or floors that weren’t built to resist fire
  • Certifying a building or signing off its fire safety

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

Surfaces we seal

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

Why act early in Shalden

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 Shalden, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

Why us?

  • Any old sealant cut out fully, not covered over
  • Approved under the ARBOMaster scheme
  • We’re fully insured
  • Neat joints and a tidy finish

What the job involves on each surface

Service penetrations

Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. We seal it with a product tested for that service and gap size.

Flats and HMOs

Converted houses often have gaps around old and new services. We seal the ones on your specification with a tested product.

Questions from Shalden

Is Shalden in your area for fire rated sealant?

Yes. We work across London and the South East, and Shalden is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job.

Do you cover smaller places like Shalden?

Yes, Shalden is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

What’s the difference between intumescent and fire-rated sealant?

Intumescent means it swells when heated. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.

How long does the job take?

Most jobs take a few hours for a handful of gaps, and longer for a whole building, including preparation and clearing up. Your quote will say how long we expect yours to take.

What do you need from me for a quote?

A short description and the location, plus pictures if you have them. We’ll ask anything else we need to know.

What do you put in the joint?

Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we’re using and why.

Can you tell me how many minutes the seal will last?

Ratings and certificates are not something we issue. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves, and we install to them.

Can new sealant go over the old?

No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.

What affects the quote in Shalden

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • How easy the joints are to reach
  • How many rooms, windows or areas are involved
  • When we can work, for business premises
  • The product the joint needs

Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Helping us 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
  • Pictures of the joints, sent by email
  • Whether it has been sealed before

We quote each job on its own. Just phone 0345 464 0079 or drop us an email with the details, and photos are welcome.
