Fire rated sealant in Hounslow West
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. We seal them with a product tested for that kind of gap. We work on door frames, service penetrations and linear gaps, and the jobs we see most are joints picked up in a fire-stopping survey and fire seals that have cracked with movement.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Where a building in Hounslow West needs to stay open, work can be planned outside normal hours.
Whatever the size of the job, it’s backed by our 12-month guarantee in Hounslow West and across Greater London.

Surface by surface
Flats and HMOs
In occupied buildings, we plan the order of work with you. We agree access to each flat and the common parts before any work starts to keep disruption down.
Linear gaps
Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement, following the tested detail.
Honest limits
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Walls or floors that weren’t built to resist fire
- Issuing a fire rating or certificate for a building
- Fire doors that need new seals, closers or hardware
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before booking.

How it works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Hounslow West. It helps if you can point us to a visitor permit or a bay close to the door.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed.
- 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.
Preparing for the visit
- Mention any parking rules near the property
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive

We quote each job on its own, so the first step is telling us about yours. Just phone 0345 464 0079 or send us an email with the details.

What affects the quote in Hounslow West
There’s no set price list, because jobs vary so much. The quote depends on:
- Whether old sealant or filler has to be cut out
- The size of the job
- When we can work, for business premises
- The number of rooms or windows
What you pay reflects the work, not guesswork. That is why we ask a few questions first and give you a clear quote before any work starts.
What to tell us for a quote
Before you ask for a quote, have a think about:
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
- The rough size of the job
- Any access issues, like height or stairs
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. When it suits you, phone 0345 464 0079 or send us an email.
Hounslow West: your questions answered
I let a flat near Hounslow station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Do you take on hotel work around Hounslow West?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Can you tell me how many minutes the seal will last?
Ratings and certificates are not something we issue. The performance comes from the product’s tested details and the specification from your assessor or designer; we install to those details and record what we did.
How long does fire rated sealant take?
As a guide, most jobs take a few hours for a handful of gaps, and longer for a whole building. Larger jobs naturally take longer, and we will say how long yours will take.
Can you match the sealant colour?
Yes. White, clear and grey are common, and other colours are available, and we will agree it with you first.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can I use normal mastic around a pipe through a fire wall?
No. It might close the gap, but it is not a fire-rated seal. A tested fire-rated product is needed, or ask us to do it.
Do you have insurance?
Yes. Mr Mastic is fully insured.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- File the fire-stopping record where your assessor can find it
- Photograph sealed gaps before they’re covered up
- Include fire stopping when you schedule refits
- Don’t fill fire-stopping gaps with ordinary foam or silicone
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and have them put right.
Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.
Do you need fire rated sealant in Hounslow West?
Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It may look fine, but it is not a fire-rated seal.
It’s worth asking for a quote if you see:
- Unsealed gaps around fire door frames
- Cracked or shrunken fire-rated sealant
- Unsealed gaps where pipes and cables go through a wall
- New service routes left unsealed after building work
If you look after a building such as Hounslow Heath Infant and Nursery School, service openings in fire-resisting walls need checking after any refurbishment.
What your quote should include
- What product goes in the joint
- How long to leave it before use
- Is the old sealant removed completely?
- Which colour the sealant will be
Why it’s worth doing now in Hounslow West
Sealant isn’t the fix for every opening. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap is not suitable for sealant, we’ll tell you. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or email us and we’ll give you an honest view and a quote.
