What the job involves on each surface

Linear gaps

A linear joint may need to allow for movement as well as fire. We choose a product and depth that suit the gap and the movement from the manufacturer’s details.

Service penetrations

Different services need different details: metal pipes, cables and plastic pipes are not treated the same. We follow the manufacturer’s tested detail for each.

About our fire rated sealant in Boarhunt

Deciding which gaps need fire stopping isn’t our role; your assessor, designer or building control sets that out. Our part is applying the specified sealant carefully, to the right depth and with the right backing. If you are dealing with linear gaps at the head of walls and gaps flagged on a fire risk assessment, we can help, on linear gaps, service penetrations and plasterboard & masonry alike.

In a village or hamlet like Boarhunt, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.

Our work is backed for twelve months, in Boarhunt and everywhere else we cover.

When something else is needed

Sealant isn’t the answer to every problem, and we will tell you before we start. It won’t solve:

  • A wall that is not a fire-resisting element to begin with
  • Certifying a building or signing off its fire safety
  • Large holes that need a different fire-stopping system

If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before you book.

Questions from Boarhunt

Can you do fire rated sealant in Boarhunt?

Yes. We work across London and the South East, and Boarhunt is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing.

Do you work for landlords with property near Portchester station?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.

Can you quote for more than one area?

Yes. More than one area can go on one quote.

What fire rating will the seal have?

Ratings and certification sit with the product’s test evidence and whoever specified the work. We apply the specified product to the manufacturer’s details and list the locations and products for you.

Which products do you use?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

Should I try DIY first?

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

Do you seal gaps around fire door frames?

Yes. Gaps behind architraves are a common job for us. The door and its fittings are a separate job for a door specialist.

Can you seal over the old sealant?

No, because it fails. We remove every bit of old sealant first.

How we quote for fire rated sealant

The price is agreed before any work begins. It’s based on:

  • Whether there’s mould to deal with
  • How many areas need sealing
  • The size of the job
  • How much old sealant there is and how hard it is to remove

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Helping us quote

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

  • The address or postcode of the job
  • The rough size of the job
  • Whether it has been sealed before
  • The problem you’ve noticed

Need a quote? Please phone 0345 464 0079 or drop us an email and tell us about the job. You’ll know what we plan to do, and what it will cost, before any work begins.

What happens if it’s left?

Leaving a gap until a refurbishment comes round can mean years with it open. Sealing the gap now is a contained job on its own and needn’t wait for anything else. Where a wall is exposed, as many are in small places like Boarhunt, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email and we will talk you through it.

The process

We bring everything the job needs with us, 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. It normally takes anything from a few hours to several days, depending on how many gaps there are. Somewhere like Boarhunt needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. Before starting, we go through the specification or action list with you.
  2. We measure every gap and note what it’s in and what passes through.
  3. Any non-fire-rated filler is removed and the faces cleaned.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. Every location is recorded with the product used for your files.

Before we arrive

  • Keep pets and children clear of the area while we work
  • Move anything stored near the joints
  • Let us know about parking restrictions

Getting a quote

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.

Fire rated sealant around Boarhunt

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

Letting a property close to Portchester station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a building such as Cams Hill School, service openings in fire-resisting walls need checking after any refurbishment. If you look after a church, hall or community building such as Church of St Nicholas, gaps around pipes and cables are worth checking after any building work there.
