Trusted fire rated sealant in Little Gaddesden

Fire rated sealant in Little Gaddesden

Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. If you are dealing with gaps around pipes and cables through fire-resisting walls and gaps where walls meet ceilings or slabs, we can help, on flats & HMOs, pipe & cable gaps and linear gaps alike.

For a small place like Little Gaddesden, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.

The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or send us an email.

Quotes for fire rated sealant in Little Gaddesden

Call for a quick quote. The main things that affect it are:

  • Any working-time requirements on site
  • The number of rooms or windows
  • The type of sealant required
  • Mould in or behind the old joints

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Asking for a quote

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

  • What the problem is, such as mould, gaps, leaks or cracking
  • Where the job is, and your postcode
  • The rough size of the job
  • Any previous sealing or DIY work

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.

How it works

Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to several days, depending on how many gaps there are. In a small place like Little Gaddesden, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  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. Every location is recorded with the product used for your files.

How to prepare

  • Mention any tricky access
  • For business premises, tell us about site rules or sign-in
  • Tell us if parking is tricky

Leave it or put it right?

Squirting in whichever sealant is nearest does not make a fire seal. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. In a small place like Little Gaddesden, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Combining jobs into one visit is generally more efficient than separate visits. We will give you a clear quote for the lot.

Little Gaddesden questions

I let a flat near Tring station. Can you help?

Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.

Is Little Gaddesden in your area for fire rated sealant?

Yes. We work across London and the South East, and Little Gaddesden is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing, and we will give you a clear price.

Do you seal gaps around fire door frames?

Yes, where the gap suits a sealant detail. We seal the frame-to-wall gap, not the door itself.

Are you insured?

Yes, we are fully insured for domestic and commercial work.

Do you provide details of the products used?

Yes. Locations and products are written up when we finish. Tell us if your assessor needs it in a particular format.

What fire rating will the seal have?

Ratings and certification sit with the product’s test evidence and whoever specified the work. We apply the specified product to the manufacturer’s details and giving you a record of where it went.

Which products do you use?

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

Do you take out the old sealant first?

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

What we’re called out for in Little Gaddesden

Over time, buildings change layout and use. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.

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

  • Open gaps behind door architraves
  • Unsealed gaps where pipes and cables go through a wall
  • Gaps filled with a product that is not fire-rated
  • Damaged fire sealant left by other trades

Letting a property close to Tring station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Questions to ask before you book

  • How the joint is cleaned and prepared
  • Which sealant they’ll use, and why
  • How long the guarantee is
  • Who does the work, and how experienced they are

How to look after the new joints

How long the joints last depends on use and care. Here’s what we suggest:

  • Never patch a fire seal with standard sealant
  • Include fire stopping when you schedule refits
  • Store the list of sealed gaps with your building paperwork
  • Get damaged fire seals looked at promptly

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.

If a fire risk assessment has flagged a gap, do not leave it for the next one. Get it sealed and recorded so you can show it was dealt with.

Should I try it myself first?

Some sealant jobs are within reach of a careful DIYer, 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.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
