Fire rated sealant in Downham
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. 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 flats & HMOs, pipe & cable gaps and linear gaps, and common reasons people get in touch are fire stopping disturbed by later work and gaps flagged on a fire risk assessment.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, whether that’s washroom resealing or fire-rated sealant around service openings. Where a building in Downham needs to stay open, work can be planned outside normal hours.

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 means you can show the action was taken. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Downham, the repair is bigger than a sealant job.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.
Why us?

Your questions about fire rated sealant in Downham
Is parking a problem for a job in Downham?
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.
Do you work for landlords with property near Grove Park station?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Do you provide details of the products used?
Yes. When the job is done, we give you the locations and products. If you need photos or a set layout, ask when you get a quote.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Can you tell me how many minutes the seal will last?
We don’t issue ratings or certificates ourselves. The performance comes from the product’s tested details and the specification from your assessor or designer.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Do you cover Downham?
We do. Our applicators work in Downham, and the service is the same as everywhere else.
Can I choose the sealant colour?
Yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before any work starts.

When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- A wall that is not a fire-resisting element to begin with
- Certifying a building or signing off its fire safety
- Openings too large for sealant, which need batts, boards or another system
If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before you book.

How the visit works
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes anything from a few hours to several days, depending on how many gaps there are. In Downham, 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.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- Where the tested detail needs backing or fill, we fit it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children
- Tell us about any previous sealing or DIY attempts

Advice
DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
If you’re set on DIY, put the effort into 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.
Surface by surface
Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We seal them along their full length.
Door frames
We deal with the gap around the frame, not the door. The door leaf, its seals and closer need a door specialist, and we will say if we spot a problem with them.
How we quote for fire rated sealant
The quote reflects the job in front of us. We take into account:
- Whether there’s mould to deal with
- The old material and how stubborn it is
- The number and length of the joints
- Any working-time requirements on site
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Where the job is, and your postcode
- The problem you’ve noticed
- If it’s domestic, commercial or a hotel
- Whether it has been sealed before
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. Whenever you are ready, phone 0345 464 0079 or email us.
Workplaces and buildings in Downham
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details. There are hotels and other places to stay in and around Downham. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
Rented homes near Grove Park station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a building such as Rangefield Primary School, fire-stopping around service openings should be restored whenever new services go in. Community buildings like St Barnabas are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.
