How we handle fire rated sealant in Norton

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. We work on linear gaps, flats & HMOs and pipe & cable gaps, and people most often call us about standard silicone or caulk in a fire-stopping gap and door frames with gaps between frame and wall.

For a small place like Norton, 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 there’s a problem with it, please call 0345 464 0079 or email us.

How the job changes by surface

Masonry and concrete

Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing so the sealant bonds.

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.

What affects the quote in Norton

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

  • Which sealant suits the joint
  • Whether the work is at height
  • Working hours on commercial sites
  • How much old sealant there is and how hard it is to remove

Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Asking for a quote

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

  • A few photos by email, if you can
  • Any access issues, like height or stairs
  • How many joints, rooms or windows are involved
  • The address or postcode of the job

We quote each job on its own. Simply phone 0345 464 0079 or drop us an email and describe the job.

Workplaces and buildings in Norton

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details. Letchworth Garden City, which Norton is part of, was laid out as a garden city in the early twentieth century. Alongside its homes, it has offices, shops, schools and workplaces, each with washrooms, kitchens and fire-rated joints to keep in order.

If you let a flat or house near Baldock station, any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a church, hall or community building such as Church of St Nicholas, older buildings that have had new heating or wiring often have service gaps worth checking. For site and facilities teams at buildings such as Norton St Nicholas CofE (VA) Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Norton is about 1 mile west of Baldock, in Hertfordshire. Every kind of property in Norton is covered for fire rated sealant, old or new, large or small. The work is guaranteed for a year. 381 places in Hertfordshire are on our list. We also work in London, around 35 miles away.

Norton: your questions answered

Will you come out to Norton?

Yes. Norton is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Can you help a landlord with a rental near Baldock station?

Yes, we work for letting agents and landlords. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.

How long does fire rated sealant take?

A typical job takes from a few hours to a few days, depending on the number of gaps and the access, including preparation and clearing up. We will confirm how long when we quote.

Can you tell me which gaps need fire stopping?

No. Your fire risk assessor, designer or building control decides that. We apply fire-rated sealant to the requirements they set.

Do you provide details of the products used?

Yes. Every gap we seal is listed with the product used so it’s there for the next inspection.

Which products do you use?

Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.

Can you seal over the old sealant?

No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

Is standard sealant good enough for a fire gap?

No. It might close the gap, but it is not a fire-rated seal. Use a product tested for that gap and service, or ask us to do it.

Landlord and commercial work in Norton

Housing providers, facilities teams and property managers book us too in Norton and across Hertfordshire. We can quote a run of properties together.

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.

Can I do it myself?

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 difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

When something else is needed

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

  • Fire doors that need new seals, closers or hardware
  • Construction that does not provide fire resistance on its own
  • Deciding what fire stopping a building needs

If in doubt, ring 0345 464 0079 or email us and we will say what we think before booking.

Joints and surfaces we work on

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

Keeping the joints in good condition

Aftercare is simple:

  • Tell trades working in the building that fire seals must be put back
  • Do not fill fire-stopping gaps with ordinary foam or silicone
  • Check risers, ceiling voids and cupboards during building checks
  • Include fire stopping when you schedule refits

File the record of locations and products with your fire safety paperwork. It saves time at the next inspection or assessment.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.

What happens on the day

When we arrive, we look over the joints with you first. We protect the surfaces around the joints before any work begins. The work generally takes from a few hours to a few days, depending on the number of gaps and the access. For a village or hamlet like Norton, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  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. Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
  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.

Getting ready for the visit

  • Try not to wet indoor joints just before the visit
  • Mention if the joints have been sealed before
  • Keep pets and children clear of the area while we work
