Fire rated sealant near Colchester

Fire rated sealant in Colchester, done properly

We can work through a building room by room or floor by floor, noting the locations and products as we go. That record is useful for your files and for whoever looks at the building next. We work on plasterboard & masonry, linear gaps and flats & HMOs, and common reasons people get in touch are holes left by a change of layout and fire seals that have cracked with movement.

Landlords with flats and shared houses in Colchester often need both kinds of work: new sealant in bathrooms and kitchens, and fire-rated joints around service openings. A single flat or a whole portfolio can be quoted.

Our work is backed for twelve months.

What affects the quote in Colchester

Some jobs are bigger than they look, and some smaller. The main factors:

  • When we can work, for business premises
  • The type of sealant required
  • The old material and how stubborn it is
  • Any mould that needs treating

Leaving a failed joint generally makes the job bigger, not smaller. If you’re unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

What to tell us for a quote

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

  • How we’d reach the joints
  • A few photos by email, if you can
  • If it’s domestic, commercial or a hotel
  • If someone has resealed it before

For a quote, phone 0345 464 0079 or email us with the location and a short description of the problem. We will give you a clear quote before any work starts.

Should I try it myself first?

A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

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.

Honest limits

A few problems are outside what sealant work can do:

  • Sign-off of the building, which sits with building control or your assessor
  • Walls or floors that weren’t built to resist fire
  • Assessing a building’s fire safety

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

How the visit works

We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of gaps, and longer for a whole building, and the area is left clean. In Colchester, we work in everything from flats and family homes to offices and hotels. For each, it helps to know about access, parking and where the joints are.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. Each gap is measured and its substrate and service noted.
  3. Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. We hand over a list of locations and products for your records.

How to prepare

  • Let us know about earlier repairs to the joints
  • Keep pets and children clear of the area while we work
  • Tell us about any water getting in

Surface by surface

Masonry and concrete

Preparation counts on brick, block and concrete. The gap is cleaned and backed where required before applying the sealant.

Service penetrations

Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. The sealant is chosen for what passes through and how wide the gap is.

What happens if it’s left?

Waiting for the next refit can leave a gap open for years. Sealing the gap now is a contained job on its own and needn’t wait for anything else. In a busy place like Colchester, a failed joint in a flat or office can send water into the space below, where it’s often found late and is bigger to put right.

We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or email us.

What fire rated sealant looks like in Colchester

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. Colchester 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 buildings such as Church of St Peter, gaps around pipes and cables are worth checking after any building work there. Managing a site like Colchester Sixth Form College? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

When to call us in Colchester

Gaps also open up as buildings move: cracked or debonded sealant leaves an open route through the wall. Damage from cleaning, knocks and maintenance adds to it.

Signs it’s time to call us include:

  • Linear gaps at the head of walls
  • Fire seals that have cracked with movement
  • Seals cut through by electricians, plumbers or data installers
  • Ordinary sealant used where a fire-rated product was needed

Rented homes near Colchester Town station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Choosing a sealant specialist

Colchester questions

I let a flat near Colchester Town station. Can you help?

Yes. We work across London and the South East, and Colchester is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
