What happens on the day

At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes from a few hours to a few days, depending on the number of gaps and the access, depending on the size of the job. In a small place like Newnham, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  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. We record what was done and flag anything that needs a different system.

How to prepare

  • For indoor joints, keep the area dry beforehand if you can
  • Clear the area around the work
  • Let us know if you’ve seen damp or leaks

How we handle fire rated sealant in Newnham

Bigger jobs can be worked through in stages, flat by flat or floor by floor, with each location and product recorded. That record is useful for your files and for whoever looks at the building next. We work on plasterboard & masonry, door frames and pipe & cable gaps, and common reasons people get in touch are unsealed gaps where pipes and cables go through a wall and gaps filled with a product that isn’t fire-rated.

If you have holiday lets, a converted barn used for business or a community building near Newnham, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

Every job comes with a 12-month guarantee.

What happens if it’s left?

Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job. Around Newnham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

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

Different surfaces, different methods

Plasterboard walls

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

Masonry and concrete

Masonry is dusty and porous, so preparation matters. The gap is cleaned and backed where required.

Fire rated sealant in Newnham: local notes

Community buildings like Church of St. Nicholas are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Aftercare tips

To keep the joints looking good and working properly:

  • Check whether a sealant can be painted before decorating over it
  • Don’t fill fire-stopping gaps with ordinary foam or silicone
  • Take photos of fire stopping before ceilings or boxing go back
  • Store the list of sealed gaps with your building paperwork

Don’t drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.

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

What sealant work cannot fix

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

  • Fire doors that need new seals, closers or hardware
  • Fire risk assessments, which need a qualified assessor
  • Construction that doesn’t provide fire resistance on its own

If you are not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.

What we seal

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

Common problems we fix in Newnham

Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk where a fire-rated seal was needed. It looks sealed, but it is not fire-rated.

People generally contact us when they notice something like this:

  • Fire seals that have cracked with movement
  • Standard silicone or caulk in a fire-stopping gap
  • Sealant items on a fire risk assessment action list
  • Linear gaps at the head of walls

For landlords with property near Hook station, any gap left by new services in shared walls should be closed with a fire-rated product.

Questions to ask before booking

  • What happens if the job turns out different
  • Who turns up on the day
  • How long to leave it before use
  • Is VAT in the price?

Choosing a sealant specialist

How we quote for fire rated sealant

The price is agreed before any work begins. It’s based on:

  • The old material and how stubborn it is
  • Any mould that needs treating
  • Working hours on commercial sites
  • The number and length of the joints

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Asking for a quote

Photos help, but a description is a good start. Try to tell us:

  • Where the job is, and your postcode
  • If it’s domestic, commercial or a hotel
  • Whether it has been sealed before
  • Access, such as stairs, a lift or height

We do not publish a price list. Instead, we give you a clear quote for your job. To arrange one, phone 0345 464 0079 or email us.

Questions from Newnham

Can you help a landlord with a rental near Hook station?

Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.

Do you cover smaller places like Newnham?

Yes. Newnham is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you remove the old sealant?

Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.

Should I try DIY first?

Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.

What information do you need?

A short description and the location. We will ask anything else we need to know.

Do you provide details of the products used?

Yes. When the job is done, we give you the locations and products. If you need pictures or a set layout, ask when you get a quote.

Will there be a smell?

Possibly a little. Any smell clears as the sealant cures.

Can you do several jobs on one visit?

Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
