How we handle fire rated sealant in Colindale
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. If you’re dealing with gaps left after a refit or conversion and unsealed gaps where pipes and cables go through a wall, we can put it right, whatever the surface.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Where a building in Colindale needs to stay open, work can be planned outside normal hours.
All our work comes with a 12-month guarantee.

What fire rated sealant looks like in Colindale
There are hotels and other places to stay in and around Colindale. Hotel work can be planned room by room, with out-of-hours working where needed. 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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
For buildings such as St Matthias the Apostle church, gaps around pipes and cables are worth checking after any building work there. If you look after a building such as Colindale Primary School, service openings in fire-resisting walls need checking after any refurbishment.

FAQs for Colindale
Is parking a problem for a job in Colindale?
Parking in Colindale, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you take on hotel work around Colindale?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or drop us an email.
Do you seal gaps around fire door frames?
Yes. Gaps behind architraves are a common job for us. Doors, seals and closers need a door specialist.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
How long does fire rated sealant take?
As a guide, most jobs take anything from a few hours to several days, depending on how many gaps there are. Bigger jobs take longer.
Can you do several jobs on one visit?
Yes, we can. More than one area can be quoted together.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.
What affects the cost of fire rated sealant
For a quick quote, just ask. The main things that affect it are:
- Access and height
- The number of rooms or windows
- When we can work, for business premises
- Whether there’s mould to deal with
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What we need to know
When you call or email, it’s useful to know:
- If someone has resealed it before
- The type of property
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you are ready, ring 0345 464 0079 or send us an email.
Surface by surface
Masonry and concrete
Holes through concrete and block are rarely neat. We measure the gap at its widest point to make sure it suits the product.
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Loose material is removed so the sealant has a firm edge.
When to call us in Colindale
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.
These are the problems we are asked about most:
- Linear gaps at the head of walls
- Gaps left after a refit or conversion
- Old fire sealant that has split or come away
- Door frames with gaps between frame and wall
As a London address, Colindale can be tricky for parking: let us know about parking bays, permits or a driveway.
Questions to ask before booking
- How long the guarantee is
- Who does the work, and how experienced they are
- Whether VAT is included
- When the joint can take water or movement
Can I do it myself?
If you’re 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 doesn’t work out, we can still put it right.
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.
What we do, step by step
There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes a few hours for a handful of gaps, and longer for a whole building in most cases. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Colindale. It helps if you can point us to a visitor permit or a bay close to the door.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Anything that isn’t fit for the job comes out, and the gap is cleaned.
- Where the tested detail needs backing or fill, we fit it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Locations and products are noted so you have them on file.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know if you’ve seen damp or leaks
Ask for a quote
We quote each job on its own, so the first step is telling us about yours. Just call 0345 464 0079 or email us with the details.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Ask every contractor to reseal any fire stopping they disturb
- Keep the record of products and locations with your fire safety documents
- Check risers, ceiling voids and cupboards during building checks
- Take pictures of fire stopping before ceilings or boxing go back
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and get them seen to.
Open gaps do not only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
