Fire rated sealant near Lower Halstow

Fire rated sealant for homes and businesses in Lower Halstow

Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, and we can record what went where. If you are dealing with joints picked up in a fire-stopping survey and door frames with gaps between frame and wall, we can help.

If you have holiday lets, a converted barn used for business or a community building near Lower Halstow, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

Quotes for fire rated sealant in Lower Halstow

We quote each job individually. This is what makes a difference:

  • How many rooms, windows or areas are involved
  • The amount of work
  • Whether the work is at height
  • Which sealant suits the joint

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

What to tell us for a quote

Photos help, but a description is a good start. Please mention:

  • Whether it’s a home or a business
  • How many joints, rooms or windows are involved
  • Photos by email, if that is easy
  • What the problem is, such as mould, gaps, leaks or cracking

Every job is quoted individually. Just call 0345 464 0079 or send us an email with the details and send photos if you have them.

Commercial buildings in Lower Halstow

For seaside hotels, guest houses and holiday lets around Lower Halstow, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. 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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Managing a site like Lower Halstow Primary School? Then fire-stopping around service openings should be restored whenever new services go in. If you look after a church, hall or community building such as Church of St Margaret of Antioch, gaps around pipes and cables are worth checking after any building work there.

How the job changes by surface

Plasterboard walls

Service holes in plasterboard are often rough and oversized. Gaps that are too big for sealant alone need a different detail.

Linear gaps

Linear gaps run along the head of walls, at floor edges and between panels. They’re sealed with a fire-rated sealant over backing where the detail calls for it.

DIY versus a professional finish

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.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Lower Halstow: your questions answered

Do you cover smaller places like Lower Halstow?

Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Do you cover Lower Halstow for fire rated sealant?

Yes. We work across London and the South East, and Lower Halstow is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we’ll send you a clear quote.

What do you put in the joint?

We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.

Can I use normal mastic around a pipe through a fire wall?

No. It might close the gap, but it isn’t a fire-rated seal. A tested fire-rated product is needed.

Should I try DIY first?

You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.

Do I need to be at home?

For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.

Do you remove the old sealant?

Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

Do you seal gaps around fire door frames?

Yes. The joint between frame and wall is sealed with a fire-rated sealant. The door leaf and its hardware need a door specialist.

When to call us in Lower Halstow

Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.

Keep an eye out for these signs:

  • Open holes round services passing through fire walls
  • Seals cut through by electricians, plumbers or data installers
  • Open gaps behind door architraves
  • Cracked or shrunken fire-rated sealant

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

How to choose a mastic man

How the visit works

The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on how many gaps there are, and we explain the cure time before we leave. Somewhere as small as Lower Halstow, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. We put in whatever backing or fill the product detail specifies.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. We record the locations and products used for your records.

Getting ready for the visit

  • Let us know about earlier repairs to the joints
  • For indoor joints, keep the area dry beforehand if you can
  • Let us know about parking restrictions

Keeping the joints in good condition

After the cure time, these simple habits help:

  • Look in service cupboards and ceiling voids from time to time
  • Keep the record of products and locations with your fire safety documents
  • Include fire stopping when you schedule refits
  • Ask which product was used before you paint

Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some can’t, so ask us which we used.

A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.

What happens if it’s left?

Squirting in whichever sealant is nearest doesn’t make a fire seal. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. In a small place like Lower Halstow, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
