Fire stopping in Westborough

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

How a job runs

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work usually takes anything from one day to a planned run of visits, depending on the number of seals and the access. If neighbouring businesses or buildings around Westborough 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. The specified backing and sealant go in to depth and are finished neatly.
  6. Anything outside the detail is reported to you rather than sealed.

Getting the site ready

  • Send any specification or drawings in advance
  • Tell us which areas need to stay in use
  • Send your site hours and access windows

About our fire stopping in Westborough

It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance in Westborough and nearby. We work on small duct penetrations where the tested detail allows, pipe penetrations and linear gaps at wall heads, and the failures we are asked to look at most are old intumescent sealant that has split away and improvised or mixed-product fire seals. One point of contact handles commercial sealant work in Westborough from the first photos to the final walk-round, for single jobs and planned programmes alike.

Around Westborough, penetration and linear seals tend to be one-building jobs. With the specification and photos of the gaps, we can give a fixed quote and bring the right products.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

When to call us in Westborough

Some service penetrations were never sealed at all. They come to light during inspections, refits or when another trade lifts a tile.

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

  • Unsealed penetrations discovered above suspended ceilings
  • Fire seals cut back for extra cables and never reinstated
  • Expanding foam used as fire stopping
  • Fire-rated sealant that has cracked or shrunk back

For a unit at a site such as Guildford Industrial Estate, less than half a mile east of Westborough, new power or data runs between office and warehouse can breach a compartment wall.

What your quote should include

  • Who will actually carry out the work
  • The named product and why it was chosen
  • How they’ll work around occupants
  • Their public liability cover

Questions to ask before you appoint anyone

Questions about Westborough

Do you seal service penetrations in hotels around Westborough?

Yes, where the specification calls for fire-rated sealant. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.

Is hospital work, at somewhere like Royal Surrey County Hospital, something you do?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day.

What site paperwork can you supply?

Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

Is any job too small?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Why deal with it now?

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down and each detail can be checked as we go. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Keeping the joints sound

Once the work is signed off, a little attention goes a long way:

  • Leave fire sealant to cure fully before covering it
  • Arrange inspection before areas are covered up
  • Settle who seals which penetrations at the start of a project
  • Record which product was used where

Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.

A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate.

Compartment walls and floors in Westborough

The area within 2 miles of Westborough holds plenty of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. Central London is about 28 miles from Westborough. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal.

For an estates team at a campus like University of Surrey, which lies north of Westborough, summer M&E works are usually followed by a round of penetration sealing. In a retail centre such as Ladymead Retail Park, 0.9 miles east of Westborough, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail.

Surface by surface

Small ducts

Some fire-rated sealant details cover small ducts. Bigger ducts and fire-resisting ductwork are normally handled with other products and we flag that rather than guess.

Drylining partitions

Plasterboard partitions are tested as a specific construction. We check that the product’s detail covers that partition type and board thickness.

When something else is needed

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Large openings beyond what any sealant detail covers
  • Issuing fire ratings or certificates for seals
  • Walls or floors that aren’t fire-resisting to begin with

If in doubt, speak to us on 01277 525 020 or send details through our quote form and we’ll say what we think.

Surfaces we seal

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