Need fire stopping in Regents Park?

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

After the work

To get the most from the new sealant:

  • Include service cupboards in routine inspections
  • Settle who seals which penetrations at the start of a project
  • Ask which product is in place before decorating
  • Record which product was used where

Keep the product data and installation details with the building’s fire safety information. Anyone resealing later needs to know which product and detail were used.

Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.

About our fire stopping in Regents Park

On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, call the office on 01277 525 020 or email the details over with the schedule or marked-up drawings and the specified product data. Tell us what records you need and we’ll confirm with the quote. If you are dealing with unsealed joints where partitions meet the slab and seals disturbed by maintenance and left open, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in Regents Park it comes down to the same thing: the right product in a properly prepared joint.

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

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Questions we’re asked in Regents Park

Do you cover business parks and estates near Regents Park, such as Liners Industrial Estate?

Yes. We cover Regents Park and the area around it, including industrial estates, business parks and retail parks such as Liners Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.

Is hospital work, at somewhere like Western Community Hospital, something you do?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Will you quote for a small job?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Do you have public liability insurance?

Yes. Mastic Doctor is fully insured, public liability included.

Do you work in Regents Park?

Yes. Regents Park is in our area. To discuss a job, ring 01277 525 020 or send photos by email.

Can you tell us what fire stopping our building needs?

No, that isn’t our role. With the designer’s details in hand, we can price the sealant elements and point out anything needing another product.

On site: what to expect

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. If neighbouring businesses or buildings around Regents Park need work too, visits can be combined. Mention the building’s opening times and we will work within them.

  1. We read the specification, drawings or penetration schedule you send and ask about anything unclear.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  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. If an opening needs something other than sealant, we tell you instead of improvising.

Before we start on site

  • Warn occupants and staff about the work
  • Tell us what induction or permit system the site runs
  • Share the asbestos register for older buildings

Quotes

How the job changes by surface

Metal pipes

Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail and we confirm each before sealing.

Cables and cable bundles

New data and power cables are the most common breach we see. We reseal around them to the specified detail, and we tell you if the bundle exceeds what sealant covers.

What we are called out for in Regents Park

Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in and later need putting right.

Clients normally get in touch after noticing something like this:

  • Open linear gaps along the top of fire-resisting walls
  • Damaged fire seals in risers and voids
  • Penetration schedules that need working through
  • Builders’ foam or ordinary silicone in compartment walls

Workshops and IT rooms at colleges like Richard Taunton Sixth Form College (1.1 miles north-east of Regents Park) are re-serviced often, leaving penetrations to seal.

Comparing quotes

  • How long is the guarantee, and what does it include?
  • Are they CHAS accredited or on Constructionline?
  • Will failed sealant be removed rather than covered?
  • Will RAMS and insurance details be available?

How to choose a sealant contractor

Why act early in Regents Park

Fire stopping is a regular point raised at inspections and handover. Late discoveries can delay handover while openings are reopened and resealed which is why earlier is better. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.

There’s no price list, since every building and every scope is different. Call for a quote and we will price your job on its own details.

Why appoint us

  • Work to your specification and the manufacturer’s guidance
  • Clear, fixed quotes
  • Workmanship guaranteed for 12 months
  • Health and safety: CHAS accredited

See our cost guide and our accreditations.

What sealant work can’t fix

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Fire risk assessments, a job for a competent assessor
  • Writing the fire-stopping specification
  • Issuing fire ratings or certificates for seals

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
  • Small duct penetrations where the tested detail allows
  • Pipe penetrations
  • Cable penetrations
  • Service gaps in risers
  • Linear gaps at wall heads

Fire stopping in Regents Park: the local picture

Regents Park has two care or nursing homes no more than 2 miles away. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.

Campus buildings at universities such as University of Southampton, 1.8 miles east of Regents Park, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. On estates like Liners Industrial Estate, 0.8 miles south-east of Regents Park, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.
