Fire stopping for commercial buildings in Stewartfield

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind. Those on your schedule are closed with the specified product. We work on pipe penetrations, joints between fire-resisting walls and floors and linear gaps at wall heads, and the usual reasons a site gets in touch are improvised or mixed-product fire seals and openings left by services added after handover. Looking for mastic applicators who cover Stewartfield? Mastic Doctor has worked for contractors, FMs and building owners since 2005.

Around smaller places such as Stewartfield, compartment walls and floors tend to be in schools, hotels, care homes and community buildings. Where services pass through, specified fire-rated sealant is installed following the manufacturer’s guidance for that wall or floor.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Commercial clients in Stewartfield

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.

When it isn’t the sealant

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Construction that lacks the fire resistance the seal relies on
  • Plastic pipes whose detail calls for a collar or wrap
  • Reviewing a building’s overall fire safety

Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we will tell you honestly.

Joints and surfaces we work on

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

Aftercare for building managers

To get the most from the new sealant:

  • Have penetrations checked while they can still be seen
  • Brief every trade that openings they make must be sealed
  • Check risers and ceiling voids after each round of works
  • File the specified details where the next contractor can find them

Store the specified product details somewhere the next contractor can find them. 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. It costs little and catches breaches early.

Why act early in Stewartfield

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Stewartfield, a repair visit takes planning, so it’s better to act early.

Whether it’s a single area or a whole estate, the same things set the price: 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.

Stewartfield: questions and answers

Do you seal service penetrations in hotels around Stewartfield?

Yes, to the specification and the product’s tested detail. Each seal follows the tested detail, and rooms are done in turn.

How do Scotland’s building standards affect fire-rated sealant in Stewartfield?

Scotland’s non-domestic Technical Handbook covers it in clause 2.1.14: penetrations keep at least the element’s fire resistance duration, with products tested for their end use. Design sits with the designer and the verifier; installation to the tested detail is our part.

Can you work while the building is occupied?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Can you quote from photos?

Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.

How much does the work cost?

We don’t publish prices, as every site differs. With photographs or drawings, we can give you a fixed quote.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Do you offer coloured sealant?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.

Where services cross fire walls in Stewartfield

The 2 miles around Stewartfield include two care or nursing homes. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. Under the Scottish non-domestic Technical Handbook, clause 2.1.14, penetrations should be fire stopped to at least the wall or floor’s fire resistance duration, using products tested for the way they’re used. Our part is installing the specified fire-rated sealant to its tested detail.

In a hotel such as The Torrance Hotel, which lies south-east of Stewartfield, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. Schools such as Duncanrig Secondary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. For a unit at a site such as Queensway Retail Park, 1 mile to the south-west of Stewartfield, any new service through a fire-resisting wall should be sealed to the tested detail.

General trades versus a specialist

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.

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. That’s why many clients bring in a specialist from the beginning.

Our process

Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact. For a building near Stewartfield, directions, keys and a contact on the day are worth sorting early. We will confirm the plan with the fixed quote.

  1. We read the specification, drawings or penetration schedule you send.
  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. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

What we need from you

  • For older buildings, check the asbestos register before work
  • Flag any permit to work we will need
