Fire-rated sealant in Newhall, Essex
We cover Newhall for intumescent and fire-rated sealant around gaps, frames and service penetrations. Old material cut out, joints cleaned and sealed neatly and a 12-month guarantee.
- Ordinary sealant used where a fire-rated product was needed
- Damaged fire sealant left by other trades

When something else is needed
New sealant can’t fix everything, and we will tell you before work begins. Sealant won’t put right:
- Openings too large for sealant, which need batts, boards or another system
- Issuing a fire rating or certificate for a building
- Doors that are not fire doors in the first place

How we handle fire rated sealant in Newhall
Fire stopping only performs as intended if it’s done to the detail: correct depth, correct backing and a product suited to the surfaces. That is the part we focus on, gap by gap. If you are dealing with fire seals that have cracked with movement and damaged fire sealant left by other trades, we can put it right.
For a pub, café, guest house or shop in or near Newhall, the washrooms and kitchen need the same attention as a big site, and fire-rated sealant around service openings should be restored after new pipes or cables go through.
Every job is covered by our one-year guarantee.

More services for Newhall
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll give you a quote.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Different surfaces, different methods
Flats and HMOs
Working in occupied flats needs some planning. We agree access to each flat and the common parts before we start to keep disruption down.
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. The gap is cleaned of dust first.
Newhall questions
Do you take on hotel work around Newhall?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
I let a flat near Harlow Mill station. Can you help?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
Can I choose the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before we start.
Can I use normal mastic around a pipe through a fire wall?
No. Standard sealants are not made or tested to stop fire. We cut it out and reseal with a fire-rated product.
Do you guarantee your work?
Yes, always. Each job is guaranteed for twelve months.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
What fire rating will the seal have?
That isn’t something we state or certify. Your specification sets the requirement, and we fit a product whose tested details meet it, recording the locations and products.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
How we quote for fire rated sealant
For a quick quote, just ask. What matters most is:
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
- The number and length of the joints
- Any mould that needs treating
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- Where the property is
- Any previous sealing or DIY work
- The type of property
- Roughly how big the job is
Asking for a quote is easy: tell us what needs doing and where and its rough size. A few photos by email make the job easier to understand, and we’ll take it from there.
Why act early in Newhall
An open gap in a fire-resisting wall is a route for smoke and fire. A proper seal lets the wall do its job again, and the work involved is often modest. Around Newhall, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or drop us an email.

Fire rated sealant around Newhall
Newhall has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Schools such as Newhall Primary Academy are buildings too, and fire-stopping around service openings should be restored whenever new services go in. If you let a flat or house near Harlow Mill 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 Mary the Virgin, gaps around pipes and cables are worth checking after any building work there.

How the visit works
There isn’t much for you to do on the day. Show us the job and we will take it from there. The work itself takes from a few hours to a few days, depending on the number of gaps and the access from start to finish. For a job in Newhall, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- Where the tested detail needs backing or fill, we fit it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- We record the locations and products used for your records.
How to prepare
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints
