How to look after the new joints

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

  • Never patch a fire seal with standard sealant
  • Don’t paint over fire sealant until it has cured
  • Include fire stopping when you schedule refits
  • Flag any open gap you spot round a pipe or cable

Any fire seal that is cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.

Open gaps do not only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.

Fire rated sealant for homes and businesses in Peacehaven

Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. We cut out the wrong material and the gap is resealed with a product tested for that use. Typical jobs include unsealed gaps where pipes and cables go through a wall and open gaps behind door architraves, on door frames, flats & HMOs and pipe & cable gaps.

For a pub, café, guest house or shop in or near Peacehaven, its washrooms and kitchen need the same sealant care as any big building.

Our work is backed for twelve months, and the guarantee is the same wherever you are.

When it isn’t the sealant

New sealant can’t fix everything, and we will tell you before we start. It won’t solve:

  • Certifying a building or signing off its fire safety
  • Fire doors that need new seals, closers or hardware
  • Big openings where sealant alone isn’t the tested solution

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

What fire rated sealant looks like in Peacehaven

For seaside hotels, guest houses and holiday lets around Peacehaven, 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 work to the specification you’re given, installing the product to its tested details.

For site and facilities teams at buildings such as Peacehaven Community School, gaps opened by contractors for new cabling are a common finding in schools and offices. For buildings such as Ascension Church, older buildings that have had new heating or wiring often have service gaps worth checking.

What the job involves on each surface

Flats and HMOs

Converted houses often have gaps around old and new services. The gaps on your list are sealed with a fire-rated product.

Service penetrations

Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. The sealant is chosen for what passes through and how wide the gap is.

Common questions in Peacehaven

Do you cover smaller places like Peacehaven?

Yes, Peacehaven is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Do you work for landlords with property near Newhaven Town station?

Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.

What do you put in the joint?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.

Should I try DIY first?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

Can new sealant go over the old?

No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.

Is the work guaranteed?

Yes. All our work carries our 12-month guarantee.

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 will mention anything we notice about the door.

Does someone need to be in?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Do you need fire rated sealant in Peacehaven?

Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. We see plenty of fire stopping that was hurried, especially where it was squeezed in at the end of a project.

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

  • Gaps left after a refit or conversion
  • Open gaps behind door architraves
  • Old fire sealant that has split or come away
  • Gaps flagged on a fire risk assessment

If you let a flat or house near Newhaven Town station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Before booking anyone

  • When the joint can take water or movement
  • Whether you can choose the colour
  • Is the old sealant removed completely?
  • Whether the sealant suits the joint

Quotes for fire rated sealant in Peacehaven

There’s no set price list. The quote depends on:

  • How many areas need sealing
  • Working hours on commercial sites

To make quoting easier, please include:

  • What the problem is, such as mould, gaps, leaks or cracking
  • Pictures of the joints, sent by email

What we do, step by step

Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes from a few hours to a few days, depending on the number of gaps and the access. For a job in Peacehaven, 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 start with the survey or action list, checking the size and surfaces of every gap.
  2. We remove any old or unsuitable filler and clean the gap.
  3. Where the tested detail needs backing or fill, we fit it.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. Locations and products are noted so you have them on file.

Getting ready for the visit

  • Keep pets and children clear of the area while we work
  • For indoor joints, keep the area dry beforehand if you can
  • Tell us about access, such as stairs, a lift or high-level joints

Advice

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.

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
