Fire rated sealant for homes and businesses in Holybourne

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’re dealing with gaps where walls meet ceilings or slabs and holes left by a change of layout, we can help, whatever the surface.

Work in a small place like Holybourne is planned ahead, journey included, so it can be fitted around guests, customers or events where possible.

The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

Why deal with it now?

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. Where a wall is exposed, as many are in small places like Holybourne, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Doing several joints on one visit is generally more efficient than separate visits. You’ll get one clear quote for the whole job.

What we do, step by step

Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere like Holybourne needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  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. Gaps are cleaned of dust and loose material.
  4. We apply and tool the sealant to the product’s tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Preparing for the visit

  • Mention any leaks or damp you’ve noticed
  • On commercial sites, let us know about site rules
  • Move anything stored near the joints

How the job changes by surface

Plasterboard walls

We check that the board around the gap is sound. Loose material is removed so the sealant has a firm edge.

Door frames

Our work is the joint between frame and wall. Doors, seals and closers are for a door specialist and we’ll mention anything we notice.

Signs you need fire rated sealant in Holybourne

Buildings are refitted and reconfigured over the years. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.

The most common problems we see are:

  • Sealant items on a fire risk assessment action list
  • Open gaps behind door architraves
  • Open joints along the top of partitions
  • Gaps left after a refit or conversion

If you look after a church, hall or community building such as Holy Rood Church, gaps around pipes and cables are worth checking after any building work there.

Before you book anyone

  • Whether the sealant suits the joint
  • What guarantee comes with the work
  • Whether all the old sealant comes out first
  • What the cure time is

Our hiring checklist

DIY versus a professional finish

A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

When something else is needed

To be straight with you, there are a few things sealant will not fix:

  • Fire doors that need new seals, closers or hardware
  • Sign-off of the building, which sits with building control or your assessor
  • Assessing a building’s fire safety

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

Joints and surfaces we work on

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

What fire rated sealant looks like in Holybourne

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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. Holybourne has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.

For landlords with property near Alton station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. For site and facilities teams at buildings such as Andrews' Endowed Church of England Primary School, service openings in fire-resisting walls need checking after any refurbishment.

Holybourne questions

Do you take on hotel work around Holybourne?

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 cover smaller places like Holybourne?

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

Do you seal gaps around fire door frames?

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

Can you tell me which gaps need fire stopping?

No. We follow the requirements from your assessor, designer or building control, and apply each product to its tested details.

Do you certify the fire stopping?

We don’t certify fire stopping or quote ratings. Our part is installing the specified product to its tested details and giving you a record of where it went.

Should I try DIY first?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

How long does fire rated sealant take?

Typically it takes from a few hours to a few days, depending on the number of gaps and the access. Bigger jobs take longer, and we will say how long yours will take.

Do I have to be there?

If the work is inside, we need someone to let us in. After that, you can carry on with your day.

What affects the quote in Holybourne

You will get a clear quote before we start. It takes into account:

  • Any mould that needs treating
  • How much old sealant there is and how hard it is to remove
  • When we can work, for business premises
  • How many rooms, windows or areas are involved

Leaving a failed joint normally makes the job bigger, not smaller. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

What we need to know

Before you ask for a quote, have a think about:

  • Pictures of the joints, sent by email
  • How we’d reach the joints
  • Where the job is, and your postcode
  • Whether it’s a home or a business

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
