Fire rated sealant for Milton homes and businesses

How the job changes by surface

Door frames

A door can only do its job if the gap behind its frame is sealed too. We fill it with a fire-rated product suited to the materials either side.

Flats and HMOs

In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We seal the gaps your assessor has identified.

Fire rated sealant in Milton

Bigger jobs can be worked through in stages, flat by flat or floor by floor, with each location and product recorded. That record is useful for your files and for whoever looks at the building next. Common call-outs are for door frames with gaps between frame and wall and unsealed gaps where pipes and cables go through a wall, across pipe & cable gaps, door frames and plasterboard & masonry.

Around a place like Milton, halls, schools and small businesses all have washrooms and kitchens used by many people. Sealant and fire-rated joints there matter as much as in any larger building.

You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

What fire rated sealant looks like in Milton

If you run a hotel, guest house or holiday let in a coastal place like Milton, 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, 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.

Schools such as Meon Junior School are buildings too, and fire-stopping around service openings should be restored whenever new services go in. Community buildings like Church of St James are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

Milton is about 1 mile south-east of Portsmouth, in Portsmouth. Jobs in Milton get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Across Portsmouth, we cover 19 places, and Milton is one of them.

What sealant work can’t fix

Some problems need a builder, plumber or other trade rather than us:

  • A wall that isn’t a fire-resisting element to begin with
  • Doors that aren’t fire doors in the first place
  • Large holes that need a different fire-stopping system

Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly.

Where we work in Milton

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

What we’re called out for in Milton

A lot of fire stopping is out of sight: above ceilings, inside risers and behind panels. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.

These are the problems we’re asked about most:

  • Fire seals that have cracked with movement
  • Unsealed gaps around fire door frames
  • Linear gaps at the head of walls
  • Seals cut through by electricians, plumbers or data installers

For landlords with property near Fratton station, any gap left by new services in shared walls should be closed with a fire-rated product.

10 questions to ask before booking

Aftercare tips

A little care helps the new joints last. We recommend:

  • Don’t paint over fire sealant until it has cured
  • Include fire stopping when you schedule refits
  • Include hidden areas like risers in routine checks
  • Keep the record of products and locations with your fire safety documents

Don’t add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. We can tell you which product we used.

Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.

What happens on the day

All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. In a smaller place like Milton, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.

  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. We record what was done and flag anything that needs a different system.

Getting ready for the visit

  • Tell us about access, such as stairs, a lift or high-level joints
  • Tell us if parking is tricky
  • Tell us about any previous sealing or DIY attempts

What affects the cost of fire rated sealant

We do not publish a price list. The quote depends on:

  • The number and length of the joints
  • Any mould that needs treating
  • Any working-time requirements on site
  • Whether the work is at height

Leaving a failed joint generally makes the job bigger, not smaller. If you are unsure, call 0345 464 0079 or email us and we’ll give you an honest view and a quote.

What we need to know

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

  • What’s wrong with the joints now
  • If someone has resealed it before
  • Photos by email, if that’s easy
  • Where the property is

To get a quote, call 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. You will have a clear quote before we start.

DIY versus a professional finish

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

FAQs for Milton

Do you cover smaller places like Milton?

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

Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.

Do you do fire sealant around door frames?

Yes, if the gap is within the product’s tested range. We seal the frame-to-wall gap, not the door itself, and we’ll mention anything we notice about the door.

Will you leave a mess?

Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.

Do you provide details of the products used?

Yes. Locations and products are written up when we finish. If you need pictures or a set layout, ask when you get a quote.

Can you tell me how many minutes the seal will last?

We do not certify fire stopping or quote ratings. We apply the specified product to the manufacturer’s details and giving you a record of where it went.
