Fire rated sealant near Houghton

Can I do it myself?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Fire rated sealant for homes and businesses in Houghton

Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it, so we work to the manufacturer’s details. We work on linear gaps, door frames and flats & HMOs, and the jobs we see most are open joints along the top of partitions and cracked or shrunken fire-rated sealant.

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

All our work comes with a one-year guarantee.

Signs you need fire rated sealant in Houghton

In some buildings the gap was filled with the wrong thing in the first place: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It looks sealed, but it isn’t fire-rated.

These are the problems we are asked about most:

  • Unsealed gaps around fire door frames
  • Ordinary sealant used where a fire-rated product was needed
  • Gaps flagged on a fire risk assessment
  • Gaps left after a refit or conversion

For buildings such as Church of All Saints, gaps around pipes and cables are worth checking after any building work there.

Questions to ask before booking

  • How long the guarantee is
  • What the quote includes, VAT included or not
  • How the colour is chosen
  • Whether all the old sealant comes out first

Choosing a sealant specialist

What fire rated sealant looks like in Houghton

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.

Letting a property close to Mottisfont & Dunbridge station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. If you look after a building such as Test Valley School, service openings in fire-resisting walls need checking after any refurbishment.

Houghton is about 6 miles north of Romsey, in Hampshire. We carry out fire rated sealant for householders, landlords and businesses in Houghton and the surrounding area. We cover 683 towns and villages across Hampshire. There’s also a page for Southampton, roughly 13 miles from Houghton.

Work for landlords, hotels and businesses

Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.

Why it’s worth doing now in Houghton

An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the sealing itself is often a contained piece of work. Where a wall is exposed, as many are in small places like Houghton, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

  • Deciding what fire stopping a building needs
  • Construction that doesn’t provide fire resistance on its own

Common questions in Houghton

Is Houghton within the area you cover?

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.

I let a flat near Mottisfont & Dunbridge station. Can you help?

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.

What sealant do you use?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

Do you do fire sealant around 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.

Is it worth trying it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Will there be a smell?

There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.

How long will you be here?

That depends on how much there is to do, but most jobs take anything from a few hours to several days, depending on how many gaps there are. We will tell you when we quote.

Do you carry out fire risk assessments?

No, we do not assess buildings. When your assessor or designer has set out what’s needed, we’ll quote for the sealant work on it.

Keeping the joints in good condition

Joint life depends on how it’s used and looked after. We suggest:

  • Photograph sealed gaps before they’re covered up
  • Tell trades working in the building that fire seals must be put back
  • Include hidden areas like risers in routine checks
  • Report cracked or damaged seals as soon as you notice them

Don’t drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.

It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the list grows.

How it works

When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on how many gaps there are. In a small place like Houghton, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Anything that isn’t fit for the job comes out, and the gap is cleaned.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. Locations and products are noted so you have them on file.

Getting ready for the visit

  • Mention if the joints have been sealed before
  • Mention any sign-in or site rules at work premises
  • Tell us about any water getting in
