DIY sealant or a professional job?

If you are 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.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

How we handle fire rated sealant in North Ascot

Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. We cut out the wrong material and the gap is resealed with a product tested for that use. Common call-outs are for gaps where walls meet ceilings or slabs and standard silicone or caulk in a fire-stopping gap, on door frames, flats & HMOs and service penetrations.

Commercial work around a smaller place like North Ascot generally means a pub, a shop, a school or small business units rather than office blocks. The work is the same as in a big building, just on a smaller scale.

Our work is backed for twelve months.

For landlords and businesses

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.

If you manage several properties in or around North Ascot, several properties can be quoted together. Just tell us the addresses and what each one needs.

Honest limits

Some problems need a builder, plumber or other trade rather than us:

  • A wall that isn’t a fire-resisting element to begin with
  • Sign-off of the building, which sits with building control or your assessor
  • Deciding what fire stopping a building needs

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

Joints and surfaces we work on

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

What affects the cost of fire rated sealant

For a quick quote, just ask. The main things that affect it are:

  • Whether old sealant or filler has to be cut out
  • Whether the work is at height
  • The size of the job
  • Working hours on commercial sites

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will explain what it covers.

What we need to know

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • The type of property
  • Any previous sealing or DIY work
  • Where the job is, and your postcode
  • What the problem is, such as mould, gaps, leaks or cracking

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

How the visit works

There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes a few hours for a handful of gaps, and longer for a whole building. In a smaller place like North Ascot, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.

  1. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  3. Dust and loose debris are cleaned from each gap.
  4. We apply and tool the sealant to the product’s tested detail.
  5. We record what was done and flag anything that needs a different system.

How to prepare

  • Mention any tricky access
  • For indoor joints, keep the area dry beforehand if you can
  • Mention any parking rules near the property

Advice

North Ascot questions

I let a flat near Ascot station. Can you help?

Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. You can call 0345 464 0079 or email us with the details for a clear quote.

Is North Ascot in your area for fire rated sealant?

Yes, North Ascot is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.

What do you put in the joint?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

Do you hold any approvals?

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

Do I have to be there?

That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.

Do you take out the old sealant first?

Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.

Do you do fire sealant around door frames?

Yes, where the gap suits a sealant detail. Our work is the gap around the frame, and we will mention anything we notice about the door.

Do you work in flats, HMOs and commercial buildings?

Yes. Occupied flats, HMOs, offices and schools are all fine. Early starts or out-of-hours work can be arranged where it’s needed.

Fire rated sealant around North Ascot

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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.

If you let a flat or house near Ascot station, any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a church, hall or community building such as Chapel of St Mary and St John, service openings in its walls need the right fire-rated sealant, as in any building.

When to call us in North Ascot

Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. Rushed fire stopping is common.

Common reasons people contact us are:

  • New service routes left unsealed after building work
  • Fire seals that have cracked with movement
  • Gaps filled with a product that isn’t fire-rated
  • Gaps around pipes and cables through fire-resisting walls

For site and facilities teams at buildings such as Ascot Heath Church of England Junior School, service openings in fire-resisting walls need checking after any refurbishment.

  • How hidden problems are handled
  • Whether the sealant suits the joint
  • When the joint can take water or movement

10 questions to ask before you book

How the job changes by surface

Masonry and concrete

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

Linear gaps

Linear gaps run along the head of walls, at floor edges and between panels. They’re sealed with a fire-rated sealant over backing where the detail calls for it.
