Fire rated sealant near Alvescot

Fire rated sealant in Alvescot

A fire seal relies on being installed the way it was tested: the right depth, the right backing and the right product for the substrate. That’s the part we focus on. We work on service penetrations, plasterboard & masonry and pipe & cable gaps, and the jobs we see most are open joints along the top of partitions and open gaps behind door architraves.

In a village or hamlet like Alvescot, 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.

Every job comes with our one-year guarantee, wherever you are in Oxfordshire.

What sealant work cannot fix

In fairness, there are a few things sealant won’t fix:

  • Walls or floors that weren’t built to resist fire
  • Fire doors that need new seals, closers or hardware
  • Certifying a building or signing off its fire safety

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

Where we work in Alvescot

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

Do you need fire rated sealant in Alvescot?

If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. We see plenty of fire stopping that was hurried.

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

  • Old fire sealant that has split or come away
  • Fire stopping disturbed by later work
  • Ordinary sealant used where a fire-rated product was needed
  • Open joints along the top of partitions

If you look after a building such as St Peter's Church of England School, fire-stopping around service openings should be restored whenever new services go in.

Questions to ask before booking

  • What product goes in the joint
  • Who turns up on the day
  • What the cure time is
  • How hidden problems are handled

How to choose a mastic man

Fire rated sealant around Alvescot

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Community buildings like Church of St Peter are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

For landlords and businesses

We work for letting agents and landlords as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.

From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

What we do, step by step

There is not much for you to do on the day. Show us the job and we will take it from there. The job generally takes anything from a few hours to several days, depending on how many gaps there are, including the tidy-up. In a small place like Alvescot, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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 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

  • Plan for the work area to be out of bounds to pets and children
  • Tell us about access, such as stairs, a lift or high-level joints
  • Move anything stored near the joints

What the job involves on each surface

Plasterboard walls

Plasterboard partitions are common in flats, offices and conversions. The sealant has to be one tested in plasterboard for the gap we’re sealing.

Masonry and concrete

Preparation counts on brick, block and concrete. We brush and vacuum the gap and use backing where the detail needs it.

Your questions about fire rated sealant in Alvescot

Is Alvescot in your area for fire rated sealant?

Yes, Alvescot is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing.

Do you cover smaller places like Alvescot?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Do you take out the old sealant first?

Yes. All of the old material is cut out and the joint cleaned.

Can I choose the sealant colour?

Most of the time, yes. We’ll explain which colours are available.

Do you provide details of the products used?

Yes. When the job is done, we give you the locations and products. If you need photos or a set layout, ask when you get a quote.

Do I have to be there?

We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.

Where do you work from?

We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

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’ll confirm how long when we quote.

Leave it or put it right?

Fire-rated sealants are less forgiving than ordinary ones. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. Where a wall is exposed, as many are in small places like Alvescot, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

Why us?

  • We’re fully insured
  • Neat joints and a tidy finish
  • Sanitary silicone with an anti-fungal additive in wet areas
  • We never seal over old sealant

Should I try it myself first?

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
