Our fire rated sealant service in Hertfordshire

We often work from an action list drawn up by a fire risk assessor for buildings in Hertfordshire. Send us the list or the survey and we will quote for the fire-rated sealant work on it. We are often asked to deal with sealant items on a fire risk assessment action list and standard silicone or caulk in a fire-stopping gap, across plasterboard & masonry, door frames and service penetrations.

There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the work takes anything from a few hours to several days, depending on how many gaps there are for a typical job.

We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
Each gap is measured and its substrate and service noted.
Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
We fit backing where needed and apply the fire-rated sealant to depth.
Every location is recorded with the product used for your files.

Local landmarks in Watford

Around Watford, our work takes us to homes and buildings near The Estcourt Arms, Watford St John's Church of England Primary School and Church of St Andrew. You’ll also find Cassiobury Park (0.8 miles west) and The Watford UTC (0.5 miles east). There’s a railway station in Watford itself: Watford Junction station. A little further out are Hilfield Castle (2.8 miles east) and Charter Place (0.5 miles south). Green spaces nearby include Harrow Weald Common.

Commercial buildings across Hertfordshire

Hertfordshire has hotels, rented property, schools and workplaces, all with sealant to maintain. Fire-rated sealant is installed to the manufacturer’s tested details, and washroom sealant is chosen for heavy use.

Hard water across most of the South East leaves limescale on sealant, grout and fittings. For any job in Hertfordshire, joints are cleaned back properly before anything new goes in.

Watford: For landlords with property near Watford Junction station, any gap left by new services in shared walls should be closed with a fire-rated product. For buildings such as Church of St Andrew, gaps around pipes and cables are worth checking after any building work there.

Any previous sealing or DIY work
The type of property
Roughly how big the job is

For a quote, ring 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. You will have a clear quote before work begins.

Looking after it afterwards

Good habits help new joints last longer. Our tips:

Take photos of fire stopping before ceilings or boxing go back
Ask every contractor to reseal any fire stopping they disturb
Allow for resealing whenever new services are run
Keep the record of products and locations with your fire safety documents

Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and have them put right.

A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.

Landlord and commercial work in Hertfordshire

Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.

For anyone letting property in or around Hertfordshire, several properties can go on one quote. Just tell us the addresses and what each one needs.

What we’re called out for in Hertfordshire

A lot of fire stopping is out of sight: above ceilings, inside risers and behind panels. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.

The problems people usually mention when they call are:

Holes left by a change of layout
Open joints along the top of partitions
Gaps around pipes and cables through fire-resisting walls
Gaps filled with a product that isn’t fire-rated

When it is not the sealant

To be straight with you, there are a few things sealant will not fix:

Large holes that need a different fire-stopping system
Certifying a building or signing off its fire safety
Deciding what fire stopping a building needs

Questions from Hertfordshire

What fire rating will the seal have?

We don’t issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves, and we install to them.

What do you need from me for a quote?

Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.

Can you work in occupied buildings?

Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. We agree access and the order of work with you first.

Do you cover Hertfordshire?

Yes. We cover Hertfordshire, as part of our work across South East England, London and Scotland. To book, call 0345 464 0079 or drop us an email.

Will it make a mess?

Very little: the area around the joints is protected first, and we tidy up before we go.

Are you insured?

Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.
