Fire rated sealant for homes and businesses in Mill Hill

Deciding which gaps need fire stopping is not our role; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. If you have gaps flagged on a fire risk assessment and door frames with gaps between frame and wall, we can help, whatever the surface.

If you run a pub, café, guest house or shop in or near Mill Hill, its washrooms and kitchen need the same sealant care as any big building.

All of our work is guaranteed for twelve months.

Your questions about fire rated sealant in Mill Hill

Is Mill Hill within the area you cover?

Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Do you work for landlords with property near Walmer station?

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

What sealant do you use?

Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we are using and why.

What do you need from me for a quote?

Just the basics: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or email us.

Can you quote for more than one area?

Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.

Can you seal over the old sealant?

No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

Are you ARBOMaster approved?

Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.

Can you give us a record of the work?

Yes. We note each location and the product that went in, so you have it on file.

Landlord and commercial work in Mill Hill

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.

In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.

What sealant work cannot fix

We’ll always be straight with you, so here’s what new sealant won’t do:

  • Issuing a fire rating or certificate for a building
  • Walls or floors that weren’t built to resist fire
  • Problems with the door itself rather than the gap around the frame

If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.

Where we work in Mill Hill

  • Pipe & cable gaps
  • Flats & HMOs
  • Plasterboard & masonry

How it works

A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. It generally takes anything from a few hours to several days, depending on how many gaps there are. For a job in Mill Hill, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. We take out any damaged or unsuitable sealant.
  3. Dust and loose debris are cleaned from each gap.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Preparing for the visit

  • On commercial sites, let us know about site rules
  • Tell us about any water getting in
  • Tell us about any previous sealing or DIY attempts

Advice

Different surfaces, different methods

Masonry and concrete

Holes through concrete and block are rarely neat. We check the gap size around the service to make sure it suits the product.

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.

Commercial buildings in Mill Hill

For seaside hotels, guest houses and holiday lets around Mill Hill, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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 work to the specification you are given, installing the product to its tested details.

For buildings such as St Richard, older buildings that have had new heating or wiring often have service gaps worth checking. Managing a site like St Mary's Catholic Primary School? Then fire-stopping around service openings should be restored whenever new services go in.

What affects the quote in Mill Hill

Jobs vary more than people expect. The main factors:

  • Access and height
  • The number and length of the joints
  • The type of sealant required
  • Working hours on commercial sites

What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start, so you know where you stand.

What to tell us for a quote

A few details help us give you an accurate quote. When you get in contact, it helps to mention:

  • How many joints, rooms or windows are involved
  • Whether it’s a home or a business
  • Photos by email, if that is easy
  • Whether it has been sealed before

Every job is quoted individually. Simply phone 0345 464 0079 or send us an email and describe the job.

How to look after the new joints

Good habits help new joints last longer. A few tips:

  • Check whether a sealant can be painted before decorating over it
  • Include fire stopping when you schedule refits
  • Tell trades working in the building that fire seals must be put back
  • Keep general-purpose foam and caulk away from fire-stopping gaps

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. Doing it at the time avoids leaving gaps behind.

What we’re called out for in Mill Hill

Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.

It’s worth asking for a quote if you see:

  • Linear gaps at the head of walls
  • Open gaps behind door architraves
  • Gaps flagged on a fire risk assessment
  • Fire seals that have cracked with movement

For landlords with property near Walmer station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
