Questions we’re asked in Startop's End

Would you work within a site like Tindal Centre?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Can you work at a site such as Silk Mill Business Park, by Startop's End?

Yes, sites like Silk Mill Business Park are within our area, along with the rest of Startop's End. Send details of the unit and the work through our quote form for a quick quote.

Will fire-rated sealant work on every penetration?

No. It depends on the tested detail for that wall or floor and service. Collars, wraps, batts and boards exist for openings sealant doesn’t cover, and we’ll tell you when that applies.

Will you quote for a small job?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Are you insured?

Yes. We are fully insured, including public liability cover.

Do you hold third-party fire-stopping installer certification?

No, and we’d rather be clear about that. Some clients require third-party installer schemes even though the law doesn’t. Where it isn’t required, we install the specified sealant to the maker’s details.

Who decides which product is used?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Fire stopping for commercial buildings in Startop's End

On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. We work on joints between fire-resisting walls and floors, pipe penetrations and linear gaps at wall heads, and the usual reasons a site gets in touch are unsealed openings around new pipes and cables and snag lists that include open service penetrations. Whoever orders the work in Startop's End, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Around smaller places like Startop's End, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Different surfaces, different methods

Risers and ceiling voids

Service risers and the voids above ceilings are where openings collect. Access to these areas is planned with you in advance along with any permits your site needs.

Drylining partitions

Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do, and the detail may call for board patching or another product.

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. Converted and older buildings near places like Startop's End tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.

In a building such as Church of All Saints, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Should maintenance staff do it?

Putting right a botched joint often costs more than sealing it well at the start, 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. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Quoting for work in Startop's End

A fixed quote reflects the actual work. It allows for:

  • Joint width, depth and condition
  • Which sealant the job calls for
  • Any access equipment needed
  • Travel to remote or island sites

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Details that help us quote

A few photos plus some basic facts will normally do. It helps to include:

  • Photos of the joints, close up and from further back
  • The asbestos register, for older buildings
  • Access details, including height
  • Where the site is, with the postcode

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, speak to us on 01277 525 020 or email drawings and photos.

From enquiry to sign-off

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and our waste is bagged and taken away as we go. For a building around Startop's End, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  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. If an opening needs something other than sealant, we tell you instead of improvising.

Preparing the site

  • Explain the parking and delivery arrangements
  • Agree which areas must stay open
  • Send asbestos survey details if the building is pre-2000
