Common questions in Perry Vale

I let a flat near Forest Hill station. Can you help?

Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.

Is parking an issue for fire rated sealant in Perry Vale?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.

What fire rating will the seal have?

We do not give ratings or certificates for our work. The requirement comes from your assessor, designer or building control, and we fit a product whose tested details meet it.

Is it worth trying it myself?

It depends on the job. High-level, external movement and fire-rated joints are professional jobs.

Do you remove the old sealant?

Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.

Can ordinary silicone be used in a fire-stopping gap?

No. A gap that needs fire stopping needs a tested fire-rated product fitted to the maker’s details.

Can you work in occupied buildings?

Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Let us know the building’s hours and we’ll plan the work to suit.

How do I get a quote for fire rated sealant in Perry Vale?

Size, access and the old material all affect the cost. Ask us for a quote.

About our fire rated sealant in Perry Vale

We can work through a building room by room or floor by floor, noting the locations and products as we go. That record is useful for your files and for whoever looks at the building next. If you are dealing with gaps where walls meet ceilings or slabs and standard silicone or caulk in a fire-stopping gap, we can put it right, whatever the surface.

London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In Perry Vale, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.

Whatever the size of the job, you get the same one-year guarantee in Perry Vale and across Greater London.

Honest limits

In fairness, there are a few things sealant won’t fix:

  • Assessing a building’s fire safety
  • Construction that does not provide fire resistance on its own
  • Sign-off of the building, which sits with building control or your assessor

If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before booking.

Surfaces we seal

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

What affects the cost of fire rated sealant

Your quote is based on your job. We take into account:

  • The number and length of the joints
  • How easy the joints are to reach
  • Any mould that needs treating
  • The old material and how stubborn it is

What you pay reflects the work, not guesswork. That is why we ask a few questions first and send you a clear quote before work begins.

Helping us quote

Photos by email are helpful but not essential. Try to tell us:

  • How we’d reach the joints
  • What’s wrong with the joints now
  • If someone has resealed it before
  • Whether it’s a home or a business

Every job is quoted individually, so start by telling us what you need. Just phone 0345 464 0079 or email us with the details.

Signs you need fire rated sealant in Perry Vale

Gaps around door frames are easily missed. The architrave hides the gap between frame and wall, so it’s easy to leave unsealed when doors are changed.

Signs it’s time to call us include:

  • Standard silicone or caulk in a fire-stopping gap
  • Unsealed gaps around fire door frames
  • Seals cut through by electricians, plumbers or data installers
  • Unsealed gaps where pipes and cables go through a wall

Perry Vale is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Before booking anyone

  • What happens if they find a problem under the old sealant
  • Whether VAT is included
  • How the surfaces are prepared before sealing
  • Whether they’re fully insured

10 questions to ask before you book

Can I do it myself?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

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.

The process

At the end, we look at the finished work together. The work normally takes anything from a few hours to several days, depending on how many gaps there are, depending on the size of the job. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Perry Vale. It helps if you can point us to a visitor permit or a bay close to the door.

  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. Unsuitable material such as ordinary foam or silicone is cut out.
  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

  • Let us know about parking restrictions
  • Let us know if you’ve seen damp or leaks
  • Let us know about stairs, lifts or work at height

Aftercare tips

So the new joints stay in good condition:

  • Check risers, ceiling voids and cupboards during building checks
  • Tell trades working in the building that fire seals must be put back
  • Keep pictures of seals that will be hidden
  • Never patch a fire seal with standard sealant

Don’t add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. Ask us if you’re not sure which product was used.

A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded.

Why act early in Perry Vale

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. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Perry Vale, the repair is bigger than the sealant job would have been.

What fire rated sealant looks like in Perry Vale

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, 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. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.

Schools such as Perrymount Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in. Rented homes near Forest Hill station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
