About our fire rated sealant in Brook Green
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. Typical jobs include open holes round services passing through fire walls and ordinary sealant used where a fire-rated product was needed, across plasterboard & masonry, linear gaps and service penetrations.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In Brook Green, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
We stand behind the work with a 12-month guarantee.

Looking after it afterwards
Aftercare is simple:
- Ask every contractor to reseal any fire stopping they disturb
- Flag any open gap you spot round a pipe or cable
- Keep pictures of seals that will be hidden
- Check whether a sealant can be painted before decorating over it
Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.
An open gap is not only a fire issue: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
How the job changes by surface
Door frames
Frame gaps are generally hidden behind the architrave. We seal any open gap to the product’s tested details so the architrave can be refitted.
Flats and HMOs
Conversions generally leave a mix of old and new service holes. The gaps on your list are sealed with a fire-rated product and the locations noted.

Leave it or put it right?
Sealant is not the fix for every opening. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap isn’t suitable for sealant, we will tell you. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Brook Green, the repair is bigger than a sealant job.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we will go through it with you.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
How we quote for fire rated sealant
The price is agreed before any work begins. It takes into account:
- The size of the job
- How much old sealant there is and how hard it is to remove
- Access and height
- Working hours on commercial sites
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
To make quoting easier, let us know:
- Where the job is, and your postcode
- Pictures of the joints, sent by email
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.
What we cannot put right
A few problems are outside what sealant work can do:
- Issuing a fire rating or certificate for a building
- Fire risk assessments, which need a qualified assessor
- Large holes that need a different fire-stopping system
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before booking.
