Why it’s worth doing now in Simpson

A quick fill with any sealant to hand isn’t fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. Around Simpson, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Call for a quick quote and we’ll explain what it covers.

Why book with us

  • Tidy, careful work
  • 4.9 on Google from 180+ five-star reviews
  • Anti-fungal sanitary silicone in wet areas
  • Approved under the ARBOMaster scheme

What happens on the day

Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes anything from a few hours to several days, depending on how many gaps there are. For a village or hamlet like Simpson, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  3. Gaps are cleaned of dust and loose material.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Getting ready for the visit

  • Keep pets and children clear of the area while we work
  • For business premises, tell us about site rules or sign-in
  • Tell us about any water getting in

Fire rated sealant in Simpson: local notes

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. There are hotels and other places to stay in and around Simpson. Hotel work can be planned room by room, with out-of-hours working where needed.

For site and facilities teams at buildings such as Charles Warren Academy, service openings in fire-resisting walls need checking after any refurbishment. For buildings such as Church of St Thomas, gaps around pipes and cables are worth checking after any building work there.

Simpson is about 1 mile north of Fenny Stratford, in Milton Keynes.

What we can’t put right

We’d rather tell you now than do work that will not last, so these are the limits:

  • Problems with the door itself rather than the gap around the frame
  • Large holes that need a different fire-stopping system
  • Sign-off of the building, which sits with building control or your assessor

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

What we seal

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

How we quote for fire rated sealant

Jobs vary more than people expect. What affects the quote:

  • The type of sealant required
  • Any mould that needs treating
  • Whether the work is at height
  • How much old sealant there is and how hard it is to remove

Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

What we need to know

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

  • The rough size of the job
  • Any previous sealing or DIY work
  • Pictures of the joints, sent by email
  • Access, such as stairs, a lift or height

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.

Aftercare tips

A little care helps the new joints last. We recommend:

  • Photograph sealed gaps before they’re covered up
  • Never patch a fire seal with standard sealant
  • Include fire stopping when you schedule refits
  • Ask which product was used before you paint

Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some cannot and we’ll tell you which one you have.

If a fire risk assessment has flagged a gap, don’t leave it for the next one. Get it sealed and recorded.

Your questions about fire rated sealant in Simpson

Do you cover smaller places like Simpson?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Do you work in hotels near Simpson?

Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.

How long will you be here?

Typically it takes anything from a few hours to several days, depending on how many gaps there are. Bigger jobs take longer, and we’ll say how long yours will take.

Is it messy?

Very little: the area around the joints is protected first, and we tidy up before we go.

Can you match the sealant colour?

Most of the time, yes. We’ll tell you which colours the right product comes in and agree one before work begins.

I rent my home. Can I book you?

Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.

Do you do fire sealant around door frames?

Yes, where the gap suits a sealant detail. We seal the frame-to-wall gap, not the door itself and we’ll tell you if we spot problems with the door.

What do you need from me for a quote?

A short description and the location, with pictures by email if possible. We will ask anything else we need to know.

Signs you need fire rated sealant in Simpson

Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ 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:

  • Holes left by a change of layout
  • Gaps where walls meet ceilings or slabs
  • Cracked or shrunken fire-rated sealant
  • Open holes round services passing through fire walls

Letting a property close to Bow Brickhill station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

What to look for in a quote

  • What happens if they find a problem under the old sealant
  • What the cure time is
  • What product goes in the joint
  • How the joint is cleaned and prepared
