Questions we’re asked in New Street

Is a smaller place like New Street outside your area?

No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Is Bowes Industrial Centre, near New Street, within your area?

Yes. Our area takes in New Street and its surroundings, with estates and business parks such as Bowes Industrial Centre included. Send details of the unit and the work through our quote form for a quick quote.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Can the sealant be colour-matched?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.

How do you deal with asbestos in old sealant?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

What site paperwork can you supply?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

How do I request a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

How we handle fire stopping in New Street

Facilities managers in New Street often find open service penetrations when ceilings come down for other work. If a specification already covers those walls and floors, we can reseal to it using the product and detail it sets out. With no specification in place, the first step sits with your designer or fire engineer, not with us. If you have builders’ foam or ordinary silicone in compartment walls and snag lists that include open service penetrations, we can help, whatever the surface. Searching for sealant specialists in New Street? Mastic Doctor has worked for contractors, FMs and building owners since 2005.

Smaller places such as New Street still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Site staff or a sealant specialist?

Paperwork matters too. 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.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Commercial clients in New Street

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. New Street can form part of a wider programme.

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.

Compartment walls and floors in New Street

Fire stopping of openings and penetrations in England falls under Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Either way, we install the specified product to its tested detail. At about 21 miles from central London, New Street is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal.

In a building such as Church of Saint Peter, any service penetration through a fire-resisting wall should be sealed to the specified detail. In a school such as Culverstone Green Primary School, fire-rated sealant goes in around service penetrations where it is specified.

New Street is about 6 miles south of Northfleet, in Kent. Looking for fire stopping in New Street? We can help, as we do across Kent. New Street is one of 931 places in Kent on our list for service penetrations. We also cover London, around 21 miles from New Street.

What sets the cost

There’s no standard rate for sealant work, because every site is different. What we look at:

  • Induction, permit and paperwork requirements
  • Specialist products, such as fire-rated or hygienic sealants
  • Joint width, depth and condition
  • Distance, for remote addresses

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.

Details that help us quote

For an accurate fixed quote, we need to understand the site. Send us:

  • Specification clauses that apply
  • Approximate linear metres or a joint schedule
  • The type of building and who uses it
  • The asbestos register, for older buildings

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or call the office on 01277 525 020 or email the details over to discuss it first.

Our process

Before we leave any area, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. Jobs in and around smaller places like New Street are typically planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Before we start on site

  • Explain the parking and delivery arrangements
  • Send any specification or drawings in advance
  • Make sure the joints can be reached

Advice

Why deal with it now?

Open penetrations multiply: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small and avoids a much larger catch-up later. One visit to deal with every failing joint makes more sense than several trips to a place like New Street. Send photographs of each area and we will quote for the lot.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Why us?

  • Failed material removed, not covered up
  • CHAS accredited
  • One number for every site we cover
  • 12-month guarantee on workmanship

Common problems we fix in New Street

A common fault is a product that was never fire-rated in the first place: builders’ foam or ordinary silicone used to fill a hole. It may look closed, but it has no tested fire performance in that position and has to be removed.

It’s worth sending us details if you spot any of the following:

  • Openings found when ceilings come down for a refit
  • Fire stopping installed outside its tested range
  • Openings left by services added after handover
  • Builders’ foam or ordinary silicone in compartment walls

Industrial units on estates such as Bowes Industrial Centre (to the north-east of New Street) often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.

Questions to ask before you book

  • Will RAMS and insurance details be available?
  • Who will actually carry out the work
  • The named product and why it was chosen
  • How the joint faces will be prepared and primed
