Fire stopping in Mayfield

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate, and we won’t pretend otherwise. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. Most enquiries involve snag lists that include open service penetrations and unsealed openings around new pipes and cables, across service gaps in risers, cable penetrations and small duct penetrations where the tested detail allows. Whoever orders the work in Mayfield, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Hotels and care homes around smaller places like Mayfield often have services added during refurbishment. We fit the specified fire-rated sealant as its published detail shows and raise it if another product is needed.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What affects the price in Mayfield

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

  • The size and state of each joint
  • Quantities, in metres or numbers
  • Induction, permit and paperwork requirements
  • Whether old sealant has to be cut out first

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

What to include in your enquiry

Diagnosis starts before we arrive. Tell us:

  • What the building is and how it’s used
  • Photos of the joints, close up and from further back
  • Where the site is, with the postcode
  • Specification clauses that apply

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. The easiest way is to give us a call on 01277 525 020 or email the details over.

Our process

Tell us your site hours and access windows and we’ll plan around them. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. For a building near Mayfield, directions, keys and a contact on the day are worth sorting early. We’ll confirm the plan with the fixed quote.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Preparing the site

  • Tell staff and tenants when we’ll be in
  • Share your working hours and any access restrictions
  • Arrange parking or a loading space

Doing it in-house

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Fire-rated sealing for Mayfield buildings

Scottish guidance (non-domestic Technical Handbook, clause 2.1.14) asks that penetrations match at least the fire resistance period of the element they pass through, with proprietary products, intumescent ones included, tested for their end use. We install what’s specified, to the product’s tested detail. Two care or nursing homes sit less than 2 miles from Mayfield. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail.

Colleges such as Newbattle Abbey College, 1.4 miles to the north-west of Mayfield, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. Residences at universities like Queen Margaret University (to the north of Mayfield) have compartment walls that must be resealed whenever services change.

Mayfield is about 2 miles south-east of Dalkeith, in Midlothian. Businesses, contractors and managing agents in Mayfield use us for work on service penetrations, as part of our coverage of Midlothian. Our Midlothian coverage takes in 34 places. Sites around Edinburgh have their own page, roughly 8 miles from Mayfield.

Business premises anywhere in EH22 are within our area for service penetrations. For a building on Chester Square, Pinewood View and Pinewood Road or nearby, send details and we will quote for service penetrations. Just outside Mayfield, we also work in D'Arcy (1 mile east), Easthouses (1 mile north-west), Newtongrange (1 mile west), Gowkshill (1 mile south-west) and Edgehead (1 mile east). Further afield, our area takes in Bonnyrigg (3 miles west), Penicuik (8 miles west), Loanhead (5 miles west), Shawfair (4 miles north-west), Danderhall (4 miles north-west) and Rosewell (4 miles west). Among the larger centres in Midlothian is Mayfield, and its commercial and public buildings are all within our area.

Leave it or put it right?

An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. The specified fire seal closes the gap for all of these. Renewing every failing joint on one visit is the sensible approach for a place like Mayfield. Send photos and we’ll quote for everything together.

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?

  • CSCS-carded applicators
  • Specification-led, product-correct work
  • Old sealant cut out, never sealed over
  • Fully insured, including public liability cover

Common problems we fix in Mayfield

When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.

Typical triggers for a call:

  • Seals disturbed by maintenance and left open
  • Open linear gaps along the top of fire-resisting walls
  • Fire stopping installed outside its tested range
  • Expanding foam used as fire stopping

Office fit-outs on sites such as McSence Business Park, less than half a mile west of Mayfield, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.

Questions to ask before you book

  • Will failed sealant be removed rather than covered?
  • Will CSCS-carded applicators be on site?
  • Whether primer will be used where the manufacturer specifies it
  • What site paperwork they can supply

Our contractor checklist

How the job changes by surface

Metal pipes

Copper and steel pipes are a common service penetration for fire-rated sealant. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on.

Masonry and concrete

Block walls and concrete floors are common substrates for penetration seals. Dust and loose debris are cleared out of the opening, with backing added if the detail requires it.

FAQs: Mayfield

Which Scottish guidance covers penetration seals in Mayfield?

Under Scotland’s non-domestic Technical Handbook (clause 2.1.14), service penetrations should keep at least the wall or floor’s fire resistance duration, using products tested for their end use. The detail is set by the designer and goes through the warrant process; we install the specified product to its tested detail.

Can you take on a job at a hospital such as Midlothian Community Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Do you offer coloured sealant?

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 confirm what’s available for the specified product when we quote.

Do you have public liability insurance?

Yes. We’re fully insured, including public liability cover.

When can the area be used after sealing?

We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Can weather delay the job?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

How much does the work cost?

There isn’t a price list, as every site differs. With photographs or drawings, we can give you a fixed quote.
