DIY versus a professional finish
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.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Fire rated sealant in Crystal Palace, done properly
Bigger jobs can be worked through in stages, flat by flat or floor by floor. That record is useful for your files and for whoever looks at the building next. We work on pipe & cable gaps, linear gaps and door frames, and common reasons people get in touch are old fire sealant that has split or come away and gaps left after a refit or conversion.
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 Crystal Palace needs to stay open, work can be planned outside normal hours.
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.

Different surfaces, different methods
Plasterboard walls
Holes in plasterboard are often cut roughly for services. Gaps that are too big for sealant alone need a different detail, and we’ll tell you.
Service penetrations
Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in.
What fire rated sealant looks like in Crystal Palace
Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. There are hotels and other places to stay in and around Crystal Palace. Hotel work can be planned room by room, with out-of-hours working where needed.
If you let a flat or house near Crystal Palace station, any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a church, hall or community building such as St Paul's, service openings in its walls need the right fire-rated sealant, as in any building.

What happens on the day
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before any work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. In a London area like Crystal Palace, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the faces cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products for your records.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Mention any tricky access
- For indoor joints, keep the area dry beforehand if you can

Advice
Landlord and commercial work in Crystal Palace
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
Looking after it afterwards
So the new joints stay in good condition:
- Store the list of sealed gaps with your building paperwork
- Take pictures of fire stopping before ceilings or boxing go back
- Allow for resealing whenever new services are run
- Keep general-purpose foam and caulk away from fire-stopping gaps
Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some can’t and we will tell you which one you have.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.

How we quote for fire rated sealant
We quote each job individually. These are the things that affect it:
- The amount of work
- Any mould that needs treating
- How many areas need sealing

What to tell us for a quote
What to tell us when you ask for a quote:
- Any access issues, like height or stairs
- Whether it’s a home or a business

- What’s wrong with the joints now

Signs you need fire rated sealant in Crystal Palace
Much fire stopping is hidden: above ceilings, inside risers and behind panels. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
These are the problems we are asked about most:
- Gaps filled with a product that is not fire-rated
- Door frames with gaps between frame and wall
- Unsealed gaps where pipes and cables go through a wall
- Fire stopping disturbed by later work
If you look after a building such as Crystal Palace School, fire-stopping around service openings should be restored whenever new services go in.
