How we handle fire rated sealant in Eton

Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. If you have damaged fire sealant left by other trades and ordinary sealant used where a fire-rated product was needed, we can help.

Work in a small place like Eton is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.

Our work is backed for twelve months, in Eton and everywhere else we cover.

Common questions in Eton

Do you take on hotel work around Eton?

Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.

I let a flat near Windsor & Eton Riverside station. Can you help?

Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.

Are you an approved applicator?

Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.

Do you remove the old sealant?

Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

Do you certify the fire stopping?

Ratings and certificates aren’t something we issue. The performance comes from the product’s tested details and the specification from your assessor or designer, and we install to them.

Can you tell me which gaps need fire stopping?

No. That is for a fire risk assessor, designer or building control. We apply fire-rated sealant to the requirements they set.

Do you provide details of the products used?

Yes. Every gap we seal is listed with the product used.

How long will you be here?

As a guide, most jobs take anything from a few hours to several days, depending on how many gaps there are. Larger jobs naturally take longer, and we will tell you how long to expect.

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, so we follow the maker’s details on every gap. Older cottages and farmhouses around Eton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Landlord and commercial work in Eton

We also work for property managers and facilities teams in Eton and across Windsor and Maidenhead. Several sites can go on one quote, and we are fully insured for the work.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

How we quote for fire rated sealant

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

  • The amount of work
  • Any mould that needs treating
  • Access and height
  • Any working-time requirements on site

What it costs depends on how much there is to do, how much old material has to come out and access to the work. You will have a clear quote before any work starts.

What to tell us for a quote

There’s no need for technical detail. It helps if you can tell us:

  • The rough size of the job
  • The type of property
  • A few photos by email, if you can
  • Any previous sealing or DIY work

To get a quote, phone 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. We’ll give you a clear price before any work starts.

Commercial buildings in Eton

There are hotels and other places to stay in and around Eton. Hotel work can be planned room by room, with out-of-hours working where needed. 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 Saint John the Evangelist are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. If you let a flat or house near Windsor & Eton Riverside station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

How it works

All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Eton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Locations and products are noted so you have them on file.

Preparing for the visit

  • Mention any sign-in or site rules at work premises
  • For indoor joints, keep the area dry beforehand if you can
  • Mention if the joints have been sealed before

What we are called out for in Eton

Door frames are a common weak spot. The architrave hides the gap between frame and wall, so it can be left open when a door is replaced.

Any of these means the joints need attention:

  • Fire stopping disturbed by later work
  • Fire seals that have cracked with movement
  • Standard silicone or caulk in a fire-stopping gap
  • Gaps where walls meet ceilings or slabs

Managing a site like Eton Porny CofE First School? Then fire-stopping around service openings should be restored whenever new services go in.

Before booking anyone

  • Whether you can choose the colour
  • Whether they seal over old material or remove it
  • Which sealant they’ll use, and why
  • What the quote includes, VAT included or not

10 questions to ask before you book

Looking after it afterwards

Aftercare is simple:

  • Photograph sealed gaps before they’re covered up
  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • Don’t paint over fire sealant until it has cured
  • Plan fire stopping into any work that goes through walls or floors

Avoid covering a sealed gap with anything that is not part of the tested detail. Repairs should use a matching fire-rated product. Ask us if you are not sure which product was used.

It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the list grows.

When it is not the sealant

New sealant cannot fix everything, and we will tell you before any work starts. It will not solve:

  • Certifying a building or signing off its fire safety
  • Construction that doesn’t provide fire resistance on its own
  • Assessing a building’s fire safety

If you’re not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.
