Fire stopping in Lee Chapel

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Fire stopping for commercial buildings in Lee Chapel

We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control. What we bring is careful installation of the specified sealant, to the maker’s guidance on buildings around Lee Chapel. The enquiries we see most involve old intumescent sealant that has split away and fire stopping installed outside its tested range, on linear gaps at wall heads, service gaps in risers and pipe penetrations. Looking for mastic applicators who cover Lee Chapel? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

Fire-rated sealing in a place like Lee Chapel is typically a single building at a time. Send the specification, drawings or photos of the openings and we’ll quote to suit.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

After the work

A few simple habits keep the new joints working:

  • Foam or ordinary sealant is never a fire-seal repair
  • Ask the designer to confirm details early on refits
  • Check risers and ceiling voids after each round of works
  • Ask which product is in place before decorating

Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way.

Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.

Questions we are asked in Lee Chapel

Can you work around term dates at a campus such as Performers College?

Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is hospital work, at somewhere like Basildon University Hospital, something you do?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, with one point of contact.

Do you need to see the site first?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs normally get a visit.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Can you reseal penetrations after our M&E works?

Yes. Send the schedule or marked-up drawings and the specified product details for a fixed quote. We can follow the services contractor floor by floor keeping pace with the programme.

What sealant work can’t fix

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Writing the fire-stopping specification
  • Construction that lacks the fire resistance the seal relies on
  • Issuing fire ratings or certificates for seals

If you’re not sure, just ring 01277 525 020 or use the quote form and we will give you a straight answer.

What we seal

  • Pipe penetrations
  • Small duct penetrations where the tested detail allows
  • Joints between fire-resisting walls and floors
  • Linear gaps at wall heads
  • Cable penetrations
  • Service gaps in risers

How a job runs

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If neighbouring businesses or buildings around Lee Chapel need work too, visits can be combined. Mention the building’s opening times and we will work within them.

  1. The specification and schedule come first, so we know which details apply.
  2. Access, permits and the order of areas are agreed with the site team.
  3. We compare every service penetration with its tested detail before sealing.
  4. Foam, ordinary sealant and debris come out.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Before we start on site

  • Have the specification and drawings to hand
  • Flag any permit to work we’ll need
  • Arrange parking or a loading space

Advice

For managing agents and facilities managers

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Fire stopping around Lee Chapel: points for this area

There are a number of hotels within about 2 miles of Lee Chapel. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. Lee Chapel is about 24 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls.

At a college such as Performers College, 2.4 miles to the south of Lee Chapel, checking penetration seals after summer M&E works is good practice. Large healthcare estates like Basildon University Hospital, 0.7 miles to the south-east of Lee Chapel, change their services often, so penetration seals are worth checking after M&E work. Shop fits on retail sites such as Pipps Hill Retail Park (to the north of Lee Chapel) can bring new services through fire-resisting walls between units, to be sealed with the specified product.

Site staff or a sealant specialist?

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

How the quote is worked out

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Whether old sealant has to be cut out first
  • Travel to remote or island sites
  • The size and state of each joint
  • Access and working height

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

What we need to price the job

A good diagnosis starts with the right details. Tell us:

  • A wide shot and a close-up of the area
  • Asbestos survey details if the building is older
  • Specification clauses that apply
  • Rough lengths or quantities, or drawings if you have them

Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. For a chat about it beforehand, speak to us on 01277 525 020 or email a schedule or drawings.
