Questions about Mayfair
Can you seal penetrations in a hotel in Mayfair after a refit?
Yes, where fire-rated sealant is the specified product. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we will tell you if the detail calls for a collar, wrap or batt instead.
Can you work around term dates at a campus such as University of Notre Dame?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Is Mayfair in your area?
Yes. We take on work across Mayfair.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
How do we ask for a quote?
The quote form is the simplest route, though you can also call the office on 01277 525 020 or use the quote form. Include photos or drawings if you have them.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Can staff carry on working while you’re here?
Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.
Fire stopping in Mayfair
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate, and we won’t pretend otherwise. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. If you have damaged fire seals in risers and voids and service penetrations left open after M&E works, we can help, on pipe penetrations, linear gaps at wall heads and small duct penetrations where the tested detail allows alike. A single leaking joint is often how a building in Mayfair first comes to us: we look at the rest while we are there and tell you what we find.
After a fit-out or new cabling in a London building, risers and ceiling voids are where open service gaps tend to be found. Fire-rated sealant goes in where it’s the specified item; where a collar, wrap or batt is called for instead, we flag it.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Should maintenance staff do it?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Diagnose, treat, sign off
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- The specification and schedule come first, so we know which details apply.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
What we need from you
- Send your site hours and access windows
- Tell staff and tenants when we’ll be in
- Send any specification or drawings in advance
Getting a fixed quote
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to give us a call on 01277 525 020 or email drawings and photos.

When something else is needed
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Reviewing a building’s overall fire safety
- Plastic pipes whose detail calls for a collar or wrap
- Approving the work on behalf of building control
Not sure which it is? You can give us a call on 01277 525 020 or send details through our quote form and we will tell you honestly before you book.
What we seal
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Pipe penetrations
How the quote is worked out
To price the job, we consider:
- Distance, for remote addresses
- The product specified
- The site’s rules and procedures
- Phasing around occupants
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
What we need to price the job
Good information means a firmer quote. Helpful details to send:
- The product your specification calls for
- Rough lengths or quantities, or drawings if you have them
- Your programme or deadline
- A wide shot and a close-up of the area
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, phone 01277 525 020 or email us.
Aftercare for building managers
To get the most from the new sealant:
- Flag new cables with no seal around them
- Include service cupboards in routine inspections
- Leave fire sealant to cure fully before covering it
- File the specified details where the next contractor can find them
Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job; found late, it can be one of many.
Building owners, agents and FMs in Mayfair
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Fire stopping in Mayfair: the local picture
Every new tenant in a London building tends to bring new cabling, and with it new holes through compartment walls. We install fire-rated sealant where it is specified and work within the building manager’s permit system. The area within 2 miles of Mayfair holds a good number of hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.
Workshops and IT rooms at colleges like London College of Fashion (under half a mile north-east of Mayfair) are re-serviced often, leaving penetrations to seal. At a university such as University of Notre Dame, 0.7 miles east of Mayfair, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. For a unit at a site such as Brompton Cross District Shopping Centre., 1.4 miles south-west of Mayfair, any new service through a fire-resisting wall should be sealed to the tested detail.
Mayfair is about 1 mile south-east of City of Westminster, in Greater London. We send applicators to Mayfair for service penetrations. 764 places across Greater London fall within our area, Mayfair among them.
