Fire rated sealant for homes and businesses in Stapleford
A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over, one gap at a time. We work on door frames, plasterboard & masonry and pipe & cable gaps, and people most often call us about seals cut through by electricians, plumbers or data installers and gaps filled with a product that isn’t fire-rated.
In a village or hamlet like Stapleford, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
There’s a 12-month guarantee on every job, large or small.

Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
If you manage several properties in or around Stapleford, several properties can go on one quote. Just tell us the addresses and what each one needs.
What the job involves on each surface
Linear gaps
Linear gaps run along the head of walls, at floor edges and between panels. They’re sealed with a fire-rated sealant over backing where the detail calls for it.
Flats and HMOs
Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified room by room.
What affects the quote in Stapleford
We quote each job individually. This is what makes a difference:
- Whether the work is at height
- Mould in or behind the old joints
- Any working-time requirements on site
- Which sealant suits the joint
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.
What to tell us for a quote
When you contact us, these details help:
- Photos by email, if that is easy
- Roughly how big the job is
- If it’s domestic, commercial or a hotel
- Where the property is
We don’t publish a price list. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or drop us an email.
What sealant work cannot fix
New sealant cannot fix everything, and we will tell you before any work starts. Sealant will not put right:
- Problems with the door itself rather than the gap around the frame
- Big openings where sealant alone is not the tested solution
- Assessing a building’s fire safety
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Ask which product was used before you paint
- Store the list of sealed gaps with your building paperwork
- Keep pictures of seals that will be hidden
- Make resealing part of every contractor’s brief
Tell other trades that the gaps have been sealed, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.
What happens on the day
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a handful of gaps, and longer for a whole building. Somewhere as small as Stapleford, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- Every location is recorded with the product used for your files.
Before we arrive
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work

Where is Mr Mastic based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Can ordinary silicone be used in a fire-stopping gap?
No. Where a fire-rated seal is needed, it has to be a product tested for that use fitted to the maker’s details.
Can you tell me how many minutes the seal will last?
Ratings and certificates are not something we issue. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves; we install to those details and record what we did.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Do you take on fire stopping in schools and offices?
Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. The order of work and access are planned with you.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
What we are called out for in Stapleford
Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It may look fine, but it isn’t a fire-rated seal.
If you can see any of these, it’s time to have the joints looked at:
- Open joints along the top of partitions
- Fire seals that have cracked with movement
- Damaged fire sealant left by other trades
- Open gaps behind door architraves
Community buildings like Church of St Mary the Virgin are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.
