Signs you need fire rated sealant in Hacton
Gaps also open up as buildings move: cracked or debonded sealant leaves an open route through the wall. Knocks, maintenance and building work damage it further.
Most people get in touch when they notice one of these:
- Linear gaps at the head of walls
- Cracked or shrunken fire-rated sealant
- New service routes left unsealed after building work
- Sealant items on a fire risk assessment action list
Schools such as Scotts Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.
Questions to ask before booking
- What happens if they find a problem under the old sealant
- Is the old sealant removed completely?
- Are they insured?
- Whether you can choose the colour
About our fire rated sealant in Hacton
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. If you’re dealing with sealant items on a fire risk assessment action list and new service routes left unsealed after building work, we can help.
In London, a commercial job often starts with access: loading bays, building rules and lifts. Timings and access are agreed with the building before work starts in Hacton, and room-by-room programmes can be planned where needed.
Big or small, you get the same one-year guarantee.

How we quote for fire rated sealant
For a quick quote, just ask. The main things that affect it are:

What to tell us for a quote
When you call or email, these details help:
- Whether it’s a home or a business
- What’s wrong with the joints now
- A few pictures by email, if you can
- The rough size of the job
For fire rated sealant in Hacton, call 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and you will get a clear quote before any work starts.
Why act early in Hacton
If an assessor has flagged gaps, it makes sense to close them before the next review. Having them sealed and recorded now gives you evidence that the item was dealt with. In a flat in Hacton, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Your questions about fire rated sealant in Hacton
Is parking an issue for fire rated sealant in Hacton?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Is Hacton in your area for fire rated sealant?
Yes, Hacton is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.
Where is Mr Mastic based?
We are a Crawley-based firm. Our area covers South East England, London and Scotland.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can you give us a record of the work?
Yes. We record the locations we’ve sealed and the products used.
Will you assess my building’s fire safety?
No. We work from the specification you give us and install to the manufacturer’s details.
Are you fully insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Can I use normal mastic around a pipe through a fire wall?
No. Ordinary silicone, caulk or foam is not tested as fire stopping. We cut it out and reseal with a fire-rated product.
Landlords, agents and businesses in Hacton
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
What we can’t put right
We will not take on work that won’t last, so here’s what sealant cannot put right:
- Walls or floors that weren’t built to resist fire
- Big openings where sealant alone isn’t the tested solution
- Certifying a building or signing off its fire safety
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.

What fire rated sealant looks like in Hacton
Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged 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, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Rented homes near Upminster station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Hacton is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

DIY versus a professional finish
If you’re 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.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
How the visit works
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. The work usually takes from a few hours to a few days, depending on the number of gaps and the access. In Hacton, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- Before starting, we go through the specification or action list with you.
- 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.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products for your records.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we’re working on
