Questions from Horsenden

Do you cover Horsenden for fire rated sealant?

Yes, Horsenden is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.

Can you help a landlord with a rental near Princes Risborough station?

Yes. We work for landlords and agents as well as homeowners. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.

Do you offer different sealant colours?

Yes. Sealants come in white, clear, grey and other colours, and we’ll agree it with you first.

Can new sealant go over the old?

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

Can you fill the gap behind a fire door frame?

Yes. Gaps behind architraves are a common job for us. Doors, seals and closers need a door specialist.

Is standard sealant good enough for a fire gap?

No. Standard sealants are not made or tested to stop fire. If it’s been used, we remove it and use the right product.

Is there a guarantee?

Yes, always. There’s a 12-month guarantee on every job.

How long does the job take?

A typical job takes from a few hours to a few days, depending on the number of gaps and the access, including preparation and clearing up. We will confirm how long when we quote.

What we do, step by step

We keep the work tidy and contained to the area we’re working on. The job generally takes anything from a few hours to several days, depending on how many gaps there are, and we tell you how long to leave it before we go. Somewhere as small as Horsenden, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. Before starting, we go through the specification or action list with you.
  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. Every location is recorded with the product used for your records.

Preparing for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Mention if the joints have been sealed before
  • Let us know about stairs, lifts or work at height

Quotes for fire rated sealant in Horsenden

Your quote is based on your job. We look at:

  • The number and length of the joints
  • The type of sealant required
  • How many rooms, windows or areas are involved
  • Any working-time requirements on site

Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

Helping us quote

To help us quote quickly, let us know:

  • If it’s domestic, commercial or a hotel
  • The problem you’ve noticed
  • If someone has resealed it before
  • Photos by email, if that is easy

Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.

Can I do it myself?

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

What fire rated sealant looks like in Horsenden

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.

Community buildings like Church of St Michael and All Angels are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. Letting a property close to Princes Risborough station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

What we are called out for in Horsenden

A lot of fire stopping is out of sight: above ceilings, inside risers and behind panels. Out of view, damage sits unnoticed until someone inspects.

If you can see any of these, it’s time to have the joints looked at:

  • Sealant items on a fire risk assessment action list
  • Fire seals that have cracked with movement
  • Open gaps behind door architraves
  • Seals cut through by electricians, plumbers or data installers

Managing a site like Princes Risborough School? Then fire-stopping around service openings should be restored whenever new services go in.

Before booking anyone

  • Whether all the old sealant comes out first
  • What guarantee comes with the work
  • What the cure time is
  • Whether you can choose the colour

Looking after it afterwards

How long the joints last depends on use and care. We suggest:

  • Photograph sealed gaps before they’re covered up
  • Plan fire stopping into any work that goes through walls or floors
  • Do not fill fire-stopping gaps with ordinary foam or silicone
  • Include hidden areas like risers in routine checks

File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.

An open gap isn’t only a fire issue: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.

Work for landlords, hotels and businesses

Housing providers, facilities teams and property managers book us too in Horsenden and across Buckinghamshire. Several sites can be quoted together, and we’re fully insured.

Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.

Why deal with it now?

Sealant is not the fix for every opening. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap isn’t suitable for sealant, we’ll tell you. Where a wall is exposed, as many are in small places like Horsenden, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

There are no prices on our website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or email us.
