Fire rated sealant for homes and businesses in Datchet

Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. We are often asked to deal with open joints along the top of partitions and standard silicone or caulk in a fire-stopping gap, across flats & HMOs, plasterboard & masonry and service penetrations.

In a smaller place like Datchet, commercial jobs tend to be smaller buildings: a pub, a surgery, a school, a shop or a few business units. The work is the same as in a big building, just on a smaller scale.

We stand behind the work with a one-year guarantee, so you’re covered after we’ve gone.

What fire rated sealant looks like in Datchet

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. Datchet has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.

If you let a flat or house near Datchet station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. For site and facilities teams at buildings such as Datchet St Mary's CofE Primary School, service openings in fire-resisting walls need checking after any refurbishment. If you look after a church, hall or community building such as Church of St Mary, gaps around pipes and cables are worth checking after any building work there.

How the visit works

When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take from a few hours to a few days, depending on the number of gaps and the access. In a smaller place like Datchet, 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. Old, damaged or unsuitable sealant is removed.
  3. Gaps are cleaned of dust and loose material.
  4. We apply and tool the sealant to the product’s tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Getting ready for the visit

  • For business premises, tell us about site rules or sign-in
  • Clear the area around the work

Datchet: your questions answered

Do you take on hotel work around Datchet?

Yes, we work for landlords and agents. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.

Are you ARBOMaster approved?

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

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

Do you come to Datchet?

Yes, we do. Datchet is part of the area we cover.

What does intumescent mean?

Fire-rated is the broad term for sealants tested for fire stopping. Intumescent ones swell in heat, and they’re one of the options. We use whichever the specification and tested details call for.

How long will you be here?

It depends on the size of the job, but as a guide it takes from a few hours to a few days, depending on the number of gaps and the access. We will tell you when we quote.

Why act early in Datchet

Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, and we work to the product details every time. Homes in smaller places like Datchet can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.

What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.

Keeping the joints in good condition

No joint lasts for ever, but care makes a real difference. A few tips:

  • Store the list of sealed gaps with your building paperwork
  • Look in service cupboards and ceiling voids from time to time
  • Plan fire stopping into any work that goes through walls or floors
  • Tell trades working in the building that fire seals must be put back

Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and have them put right.

Open gaps don’t only matter in a fire: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.

What sealant work cannot fix

A few problems are outside what sealant work can do:

  • Doors that are not fire doors in the first place
  • Large holes that need a different fire-stopping system
  • Fire risk assessments, which need a qualified assessor

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

Surfaces we seal

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

What the job involves on each surface

Door frames

The gap between a door frame and the wall around it needs sealing as well as the door itself. We fill it with a fire-rated product suited to the materials either side.

Plasterboard walls

In plasterboard walls, the condition of the board edge matters. Crumbling edges are cleaned back before the sealant goes in.

DIY sealant or a professional job?

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed 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.
