Fire rated sealant near Sonning Common

What we’re called out for in Sonning Common

In some buildings the gap was filled with the wrong thing in the first place: general-purpose foam, everyday silicone or caulk where a fire-rated seal was needed. It may look fine, but it is not a fire-rated seal.

It’s worth asking for a quote if you see:

  • Open gaps behind door architraves
  • Ordinary sealant used where a fire-rated product was needed
  • Gaps around pipes and cables through fire-resisting walls
  • Holes left by a change of layout

Managing a site like Sonning Common Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

10 questions to ask before you book

How we handle fire rated sealant in Sonning Common

Until it’s heated, intumescent sealant behaves like an ordinary sealant; 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. If you are dealing with gaps where walls meet ceilings or slabs and joints picked up in a fire-stopping survey, we can help.

If you run a pub, café, guest house or shop in or near Sonning Common, its washrooms and kitchen need the same sealant care as any big building.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What happens if it’s left?

Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job and needn’t wait for anything else. Around Sonning Common, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

What you get with us

  • Any old sealant cut out fully, not covered over
  • 20+ years of sealant experience
  • Fully insured
  • Homes, businesses and hotels

Fire rated sealant in Sonning Common: local notes

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 The Church of Christ the King are part of the picture too: gaps around pipes and cables are worth checking after any building work there. Rented homes near Henley-On-Thames station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

DIY sealant or a professional job?

If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

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.

What we do, step by step

Good joint work is mostly preparation, so that’s where we spend the time. 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. A visit to Sonning Common is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  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. Every location is recorded with the product used.

Preparing for the visit

  • Try not to wet indoor joints just before the visit
  • For business premises, tell us about site rules or sign-in
  • Move anything stored near the joints

Landlord and commercial work in Sonning Common

For anyone letting property in or around Sonning Common, several properties can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

When it isn’t the sealant

In fairness, some problems need a different trade:

  • Fire doors that need new seals, closers or hardware
  • Issuing a fire rating or certificate for a building
  • A wall that is not a fire-resisting element to begin with

If in doubt, ring 0345 464 0079 or email us and we will say what we think before booking.

What we seal

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

What affects the quote in Sonning Common

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • Which sealant suits the joint
  • Whether old sealant or filler has to be cut out
  • How many areas need sealing
  • Access and height

Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Asking for a quote

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

  • What’s wrong with the joints now
  • Where the job is, and your postcode
  • Photos by email, if that is easy
  • Access, such as stairs, a lift or height
