About our fire rated sealant in Findon Valley

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 apply it to the depth its tested detail calls for. We work on door frames, linear gaps and plasterboard & masonry, and the jobs we see most are ordinary sealant used where a fire-rated product was needed and cracked or shrunken fire-rated sealant.

Community buildings, schools and small businesses around places like Findon Valley have washrooms and kitchens that see a lot of use. Their sealant and fire-rated joints are as important as those in any bigger building.

Our work is backed for twelve months.

Do you need fire rated sealant in Findon Valley?

Door frames are a common weak spot. The architrave hides the gap between frame and wall, so it’s easy to leave unsealed when doors are changed.

The most common problems we see are:

  • Seals cut through by electricians, plumbers or data installers
  • Open holes round services passing through fire walls
  • Unsealed gaps around fire door frames
  • Cracked or shrunken fire-rated sealant

For buildings such as All Saints, older buildings that have had new heating or wiring often have service gaps worth checking.

What your quote should include

  • When the joint can take water or movement
  • Whether they’re fully insured
  • What happens if the job turns out different
  • How much experience the applicator has

Choosing a sealant specialist

How the job changes by surface

Masonry and concrete

Holes through concrete and block are rarely neat. We measure the gap at its widest point against the product’s tested range.

Linear gaps

Long, narrow gaps appear where walls meet slabs and ceilings. We seal them to the tested detail, with backing where it’s needed.

Landlord and commercial work in Findon Valley

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

What sealant work cannot fix

We won’t take on work that will not last, so these are the limits:

  • Fire doors that need new seals, closers or hardware
  • Walls or floors that weren’t built to resist fire
  • Sign-off of the building, which sits with building control or your assessor

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

DIY sealant or a professional job?

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

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.

Findon Valley: your questions answered

I let a flat near West Worthing station. Can you help?

Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. You can phone 0345 464 0079 or email us with the details for a clear quote.

Do you take on hotel work around Findon Valley?

Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.

Will you assess my building’s fire safety?

No, we don’t assess buildings. When your assessor or designer has set out what’s needed, we will quote for the sealant work on it.

Can you do several jobs on one visit?

Yes. Tell us about everything you’d like done and we will quote it together.

Do you have insurance?

Yes. We’re fully insured.

How long does fire rated sealant take?

A typical job takes a few hours for a handful of gaps, and longer for a whole building, including the preparation. We will confirm how long when we quote.

Is standard sealant good enough for a fire gap?

No. Standard sealants aren’t made or tested to stop fire. We cut it out and reseal with a fire-rated product.

Is it messy?

We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.

What we do, step by step

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to several days, depending on how many gaps there are and we leave things clean and tidy. A visit to Findon Valley is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. Access to each area is agreed so the work can run in order.
  2. Old, damaged or unsuitable sealant is removed.
  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.

Before we arrive

  • Let us know about earlier repairs to the joints
  • Mention any tricky access
  • For business premises, tell us about site rules or sign-in

Getting a quote

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.

Looking after it afterwards

Good habits help new joints last longer. A few tips:

  • Allow for resealing whenever new services are run
  • Get damaged fire seals looked at promptly
  • Take pictures of fire stopping before ceilings or boxing go back
  • Ask every contractor to reseal any fire stopping they disturb

Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some can’t.

An open gap isn’t only a fire issue: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
