Do you need fire rated sealant in Deptford?
Movement in the structure can open gaps too: cracked or debonded sealant leaves an open route through the wall. Knocks, maintenance and building work damage it further.
Signs it’s time to call us include:
- Sealant items on a fire risk assessment action list
- Gaps around pipes and cables through fire-resisting walls
- Open gaps behind door architraves
- Ordinary sealant used where a fire-rated product was needed
As a London address, Deptford can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Questions from Deptford
Is parking an issue for fire rated sealant in Deptford?
Parking in Deptford, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Do you take on hotel work around Deptford?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
Can you tell me how many minutes the seal will last?
Ratings and certificates aren’t 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.
Can you tell me which gaps need fire stopping?
No. That is for a fire risk assessor, designer or building control. We apply fire-rated sealant to the requirements they set.
Can you give us a record of the work?
Yes. You get a list of where we worked and what we used to keep with your fire safety documents.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
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.
Can you do several jobs on one visit?
Yes. Just list everything you need.
Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Different surfaces, different methods
Flats and HMOs
Working in occupied flats needs some planning. We agree access to each flat and the common parts before we start so residents know what to expect.
Service penetrations
Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in over any backing the detail calls for.
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. It usually takes a few hours for a handful of gaps, and longer for a whole building. In Deptford, 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.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Locations and products are noted so you have them on file.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints
- Try not to wet indoor joints just before the visit

There are hotels and other places to stay in and around Deptford. Hotel work can be planned room by room, with out-of-hours working where needed. Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange.
For site and facilities teams at buildings such as Tidemill Academy, service openings in fire-resisting walls need checking after any refurbishment. Rented homes near Deptford station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.

What affects the quote in Deptford
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How many areas need sealing
- Any mould that needs treating
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
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’ll explain what it covers.
What we need to know
To help us quote quickly, let us know:
- Where the job is, and your postcode
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
- A few photos by email, if you can
We don’t publish a price list, as no two jobs are quite the same. Instead, we give you a clear price for your job. To arrange one, ring 0345 464 0079 or email us.
What happens if it’s left?
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 a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Honest limits
To be straight with you, there are a few things sealant won’t fix:
- Problems with the door itself rather than the gap around the frame
- A wall that is not a fire-resisting element to begin with
- Certifying a building or signing off its fire safety
