How we handle fire rated sealant in Buntingford

Fire stopping only performs as intended if it’s done to the detail: correct depth, correct backing and a product suited to the surfaces. That’s the part we focus on, one gap at a time. Common call-outs are for door frames with gaps between frame and wall and gaps filled with a product that isn’t fire-rated, across service penetrations, door frames and pipe & cable gaps.

Commercial work around a smaller place like Buntingford usually means a pub, a shop, a school or small business units rather than office blocks. The work is the same as in a big building, just on a smaller scale.

Every job is covered by a one-year guarantee.

What sealant work cannot fix

We won’t take on work that won’t last, so these are the limits:

  • Openings too large for sealant, which need batts, boards or another system
  • Fire risk assessments, which need a qualified assessor
  • Walls or floors that weren’t built to resist fire

If in doubt, phone 0345 464 0079 or email us and we will say what we think before you book.

Where we work in Buntingford

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

Different surfaces, different methods

Service penetrations

Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. We seal it with a product tested for that service and gap size.

Plasterboard walls

In plasterboard walls, the condition of the board edge matters. Crumbling edges are cleaned back before the sealant goes in.

Why it’s worth doing now in Buntingford

Fire-rated sealants need more care than everyday sealant. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. In a smaller place like Buntingford, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.

Combining jobs into one visit is generally more efficient than separate visits. You will get one clear quote for the whole job.

Can I do it myself?

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

Buntingford questions

What guarantee comes with fire rated sealant in Buntingford?

Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.

Is Buntingford within the area you cover?

Yes, Buntingford is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Can new sealant go over the old?

No, because it fails. The old sealant always comes out first.

Are you fully insured?

Yes, we’re fully insured.

What does intumescent mean?

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

Where are you based?

Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.

Do you provide details of the products used?

Yes. We record the locations we’ve sealed and the products used.

Do you certify the fire stopping?

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 list the locations and products for you.

Fire rated sealant in Buntingford: local notes

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.

Community buildings like Church of St Peter are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. Managing a site like Millfield First and Nursery School? Then service openings in fire-resisting walls need checking after any refurbishment.

What affects the quote in Buntingford

Call for a quick quote. What matters most is:

  • Any working-time requirements on site
  • How much there is to do
  • The old material and how stubborn it is
  • Mould in or behind the old joints

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

What we need to know

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

  • Access, such as stairs, a lift or height
  • If it’s domestic, commercial or a hotel
  • A few pictures by email, if you can
  • Roughly how big the job is

If you are in Buntingford and need fire rated sealant, phone 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.

What we do, step by step

At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for a handful of gaps, and longer for a whole building, depending on how much there is to do. A visit to Buntingford is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  3. Dust and loose debris are cleaned from each gap.
  4. We apply and tool the sealant to the product’s tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

How to prepare

  • Let us know about stairs, lifts or work at height
  • Plan for the work area to be out of bounds to pets and children
  • Clear the area around the work
