About our fire rated sealant in Streatham
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 detail is what we take care over. Common call-outs are for damaged fire sealant left by other trades and holes left by a change of layout, across flats & HMOs, service penetrations and pipe & cable gaps.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. In Streatham, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Common questions in Streatham
Is Streatham in your area for fire rated sealant?
Yes, Streatham is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear quote.
Do you work for landlords with property near Streatham station?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little.
Can I use normal mastic around a pipe through a fire wall?
No. A gap that needs fire stopping needs a tested fire-rated product fitted to the maker’s details.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator.
Do you work in flats, HMOs and commercial buildings?
Yes. We regularly work in flats, HMOs, schools and offices while they’re in use and we plan access around the people using them. Out-of-hours work can be arranged.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
When it is not the sealant
A few problems are outside what sealant work can do:
- A wall that isn’t a fire-resisting element to begin with
- Certifying a building or signing off its fire safety
- Fire doors that need new seals, closers or hardware
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before booking.

Work for landlords, hotels and businesses
We work for landlords and agents as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
When to call us in Streatham
Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
Any of these means the joints need attention:
- Holes left by a change of layout
- Open gaps behind door architraves
- Ordinary sealant used where a fire-rated product was needed
- Gaps where walls meet ceilings or slabs
As a London address, Streatham can be tricky for parking: let us know about parking bays, permits or a driveway.

What happens on the day
You do not need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes from a few hours to a few days, depending on the number of gaps and the access in most cases. In Streatham, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- 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.
- Unsuitable material such as ordinary foam or silicone is cut out.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Move anything stored near the joints
- Mention any tricky access
Ask for a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.

How the job changes by surface
Masonry and concrete
Holes through concrete and block are rarely neat. We measure the gap at its widest point against the product’s tested range.
Door frames
Behind most architraves is a gap between frame and wall. Where it’s open, we seal it to the product’s details for that gap size so the architrave can be refitted.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

Leave it or put it right?
Items left open on a fire risk assessment tend to come back at the next review. Having them sealed and recorded now gives you evidence that the item was dealt with. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Streatham.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

What fire rated sealant looks like in Streatham
Many London buildings have tight access and loading restrictions, 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, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.
If you look after a church, hall or community building such as St Leonard's Church, older buildings that have had new heating or wiring often have service gaps worth checking. Rented homes near Streatham station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
