Fire rated sealant in Wivenhoe
Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it. We are often asked to deal with gaps around pipes and cables through fire-resisting walls and unsealed gaps around fire door frames, across pipe & cable gaps, linear gaps and door frames.
Commercial work around a smaller place like Wivenhoe usually means a pub, a shop, a school or small business units rather than office blocks. The work is the same as in a big building, just on a smaller scale.

Commercial buildings in Wivenhoe
For seaside hotels, guest houses and holiday lets around Wivenhoe, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. 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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
For buildings such as The Church of St Mary, gaps around pipes and cables are worth checking after any building work there. If you look after a building such as Millfields Primary School, service openings in fire-resisting walls need checking after any refurbishment. For landlords with property near Wivenhoe station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

What else we do in Wivenhoe
What affects the quote in Wivenhoe
Your quote is based on your job. We look at:
- Which sealant suits the joint
- Access and height
- How many rooms, windows or areas are involved
- The number and length of the joints
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Helping us quote
When you call or email, these details help:
- Roughly how big the job is
- Where the job is, and your postcode
- Any access issues, like height or stairs
- What’s wrong with the joints now
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.
What happens on the day
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes anything from a few hours to several days, depending on how many gaps there are for a typical job. A visit to Wivenhoe is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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 gap 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.
Before we arrive
- Try not to wet indoor joints just before the visit
- Let us know if you’ve seen damp or leaks
- Mention any tricky access

It all starts with a short chat. Describe the problem, the location and the size of the job. When it suits you, ring 0345 464 0079 or email us.

- Issuing a fire rating or certificate for a building

If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before you book.
Joints and surfaces we work on
- Linear gaps
- Plasterboard & masonry
- Pipe & cable gaps
- Door frames
- Flats & HMOs
- Service penetrations
What happens if it’s left?
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. A proper seal lets the wall do its job again, and the work involved is often modest. In an older home around Wivenhoe, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or send us an email and we’ll talk you through it.

Aftercare tips
A little care helps the new joints last. We recommend:
- Never patch a fire seal with standard sealant
- Photograph sealed gaps before they’re covered up
- Plan fire stopping into any work that goes through walls or floors
- Report cracked or damaged seals as soon as you notice them
Avoid covering a sealed gap with anything that is not part of the tested detail. If it needs repair, use the same type of product. Ask us if you are not sure which product was used.
Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.
Wivenhoe questions

Is Wivenhoe within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Will we have a record of what was sealed?
Yes. When the job is done, we give you the locations and products. If you need photos or a set layout, ask when you get a quote.
Can I add another job to the 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.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
How long does fire rated sealant take?
That depends on the amount of work, but most jobs take a few hours for a handful of gaps, and longer for a whole building. We’ll tell you when we quote.
Can you match the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available, and we’ll agree it with you first.
What the job involves on each surface
Flats and HMOs
Conversions usually leave a mix of old and new service holes. The gaps on your list are sealed with a fire-rated product and record where they are.
Door frames
A door can only do its job if the gap behind its frame is sealed too. We fill it with a fire-rated product suited to the materials either side.
For landlords and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
