About our fire rated sealant in Blewbury

Door frame gaps, linear joints and holes around services all have their own details. Measuring the gap and checking what it’s made of comes first, then the sealant goes in to the depth the product’s details set. If you have gaps filled with a product that isn’t fire-rated and joints picked up in a fire-stopping survey, we can put it right, on pipe & cable gaps, service penetrations and plasterboard & masonry alike.

In a village or hamlet like Blewbury, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Your questions about fire rated sealant in Blewbury

Do you work for landlords with property near Didcot Parkway station?

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

Is Blewbury within the area you cover?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you hold any approvals?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

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.

How long will you be here?

That depends on the amount of work, but most jobs take a few hours for a handful of gaps, and longer for a whole building. We will tell you when we quote.

What do you put in the joint?

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

What information do you need?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Can you work in occupied buildings?

Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. The order of work and access are planned with you.

Why deal with it now?

Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job and needn’t wait for anything else. Older cottages and farmhouses around Blewbury can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

Should I try it myself first?

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas 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 fails, we can still redo it.

When it is not the sealant

It helps to know what we can’t do:

  • Deciding what fire stopping a building needs
  • Certifying a building or signing off its fire safety
  • Large holes that need a different fire-stopping system

Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

Surfaces we seal

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

Work for landlords, hotels and businesses

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

How we quote for fire rated sealant

There’s no set price list. The quote depends on:

  • The number of rooms or windows
  • How much there is to do
  • How easy the joints are to reach
  • Whether old sealant or filler has to be cut out

Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or email us and we will give you an honest view and a quote.

Asking for a quote

To help us quote quickly, please include:

  • Any previous sealing or DIY work
  • Photos by email, if that’s easy
  • What the problem is, such as mould, gaps, leaks or cracking
  • The rough size of the job

Every job is quoted individually, so the first step is telling us about yours. Simply call 0345 464 0079 or send us an email and describe the job and send photos if you have them.

What happens on the day

Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. It usually takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere like Blewbury needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. We take out any damaged or unsuitable sealant.
  3. Dust and loose debris are cleaned from each gap.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. We record what was done and flag anything that needs a different system.

Preparing for the visit

  • Mention any leaks or damp you’ve noticed
  • Let us know about parking restrictions
  • Move anything stored near the joints

Advice

Looking after it afterwards

Simple care keeps the joints in good condition. Our advice:

  • Keep pictures of seals that will be hidden
  • Plan fire stopping into any work that goes through walls or floors
  • Ask which product was used before you paint
  • Never patch a fire seal with standard sealant

Do not add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. We can tell you which product we used.

An open gap isn’t only a fire issue: noise, draughts and even pests can come through too. Sealing them early helps on every front.

Commercial buildings in Blewbury

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 work to the specification you’re given, installing the product to its tested details.

If you look after a building such as Blewbury Endowed Church of England Primary School, fire-stopping around service openings should be restored whenever new services go in. Letting a property close to Didcot Parkway station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Community buildings like Church of St Michael are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.
