Fire rated sealant near Grafty Green

Fire rated sealant in Grafty Green, done properly

We often work from an action list drawn up by a fire risk assessor on buildings across Grafty Green. If you share the list, we can quote for the gaps that need fire-rated sealant. Typical jobs include unsealed gaps where pipes and cables go through a wall and cracked or shrunken fire-rated sealant, across flats & HMOs, linear gaps and service penetrations.

Somewhere as small as Grafty Green, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

Every job is covered by a 12-month guarantee.

What happens if it’s left?

Doing it once, properly, beats doing it twice. If the details weren’t followed, the seal may need redoing when the building is next checked. In a small place like Grafty Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and give you a clear price before any work starts.

What sealant work cannot fix

We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:

  • Big openings where sealant alone isn’t the tested solution
  • A wall that is not a fire-resisting element to begin with
  • Doors that aren’t fire doors in the first place

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

Joints and surfaces we work on

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

What affects the quote in Grafty Green

Your quote is based on your job. We take into account:

  • The number of rooms or windows
  • How easy the joints are to reach
  • Mould in or behind the old joints
  • How much old sealant there is and how hard it is to remove

Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will go through it with you.

Helping us quote

When you call or email, it’s useful to know:

  • If someone has resealed it before
  • Access, such as stairs, a lift or height
  • The type of property
  • Where the job is, and your postcode

Asking for a quote is easy: let us know the job and the location. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.

DIY versus a professional finish

If you are set on DIY, put the effort into 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.

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

How to look after the new joints

Once the sealant has cured, a few habits help it last:

  • Don’t paint over fire sealant until it has cured
  • Allow for resealing whenever new services are run
  • Keep photos of seals that will be hidden
  • Look in service cupboards and ceiling voids from time to time

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

It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole.

How it works

There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of gaps, and longer for a whole building for a typical job. Somewhere as small as Grafty Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. Where the tested detail needs backing or fill, we fit it.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Finally, we list where we worked and what we used, for your records.

Before we arrive

  • Tell us about any previous sealing or DIY attempts
  • Mention any sign-in or site rules at work premises
  • Let us know about stairs, lifts or work at height

Ask for a quote

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. When it suits you, phone 0345 464 0079 or email us.

What fire rated sealant looks like in Grafty Green

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, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.

For buildings such as Church of St Nicholas, gaps around pipes and cables are worth checking after any building work there. Schools such as Platts Heath Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. Rented homes near Lenham station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Grafty Green is about 8 miles south-east of Maidstone, in Kent. Anywhere in ME17, we can carry out fire rated sealant at your property. Our area takes in 922 places across Kent, from the larger towns to small villages. We also work in Chelmsford, around 37 miles away.

Common questions in Grafty Green

I let a flat near Lenham station. Can you help?

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

Do you cover smaller places like Grafty Green?

Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Do you take on fire stopping in schools and offices?

Yes. We regularly work in flats, HMOs, schools and offices while they’re in use. Early starts or out-of-hours work can be arranged.

Can you quote for more than one area?

Yes, we can. More than one area can go on one quote.

Will the old sealant be removed?

Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

Are you ARBOMaster approved?

Yes. Mr Mastic is an ARBOMaster approved applicator.

Can I do it myself?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Can you fill the gap behind a fire door frame?

Yes, where the gap suits a sealant detail. We seal the frame-to-wall gap, not the door itself.

How the job changes by surface

Flats and HMOs

Converted houses often have gaps around old and new services. The gaps on your list are sealed with a fire-rated product and the locations noted.

Linear gaps

A linear joint may need to allow for movement as well as fire. The product and depth are chosen to suit both.
