About our fire stopping in Penicuik

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. If you have expanding foam used as fire stopping and unsealed joints where partitions meet the slab, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Penicuik is the same: the right product in a properly prepared joint.

Towns the size of Penicuik have schools, care homes, health centres and offices divided into fire compartments. The Scottish Technical Handbook expects penetrations to be fire stopped to the wall or floor’s fire resistance duration, using products tested for how they’re actually used.

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

What we are called out for in Penicuik

Mixing products or improvising a detail breaks the link with the test evidence. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.

What tends to prompt an enquiry:

  • Fire-rated sealant that has cracked or shrunk back
  • Penetration schedules that need working through
  • Hidden openings found during inspections
  • Unsealed joints where partitions meet the slab

Hotels such as Craigiebield House Hotel (0.5 miles south-west of Penicuik) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

What to look for in a quote

  • Is the sealant right for the movement and the substrate?
  • How long is the guarantee, and what does it include?
  • How joint depth will be controlled
  • Their pre-qualification and accreditations

How to choose a sealant contractor

Diagnose, treat, sign off

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Several buildings in and around Penicuik can be done on one programme. Share your working hours and access arrangements and we’ll fit in.

  1. The specification and schedule come first, so we know which details apply.
  2. We plan the sequence of floors, risers and voids with you.
  3. We compare every service penetration with its tested detail before sealing.
  4. Unsuitable material is removed and the opening cleaned first.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

Getting the site ready

  • Confirm the product named in the specification
  • Arrange parking or a loading space
  • Move anything stored against the joints

When it isn’t the sealant

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

  • Deciding what a wall or floor needs, which belongs to the designer
  • Gaps in walls that were never built as compartment walls
  • Fire doors, dampers or other fire safety equipment

If you are not sure, just call the office on 01277 525 020 or email the details over and we will give you a straight answer before you book.

What we seal

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

Fire stopping in Penicuik: the local picture

Scotland has its own building standards: the non-domestic Technical Handbook (clause 2.1.14) says service penetrations should be fire stopped to at least the fire resistance duration of the wall or floor, with proprietary products, intumescent ones included, tested for their end use. Where fire-rated sealant is specified, that’s what we install, to the tested detail. Penicuik has several hotels close by, all within 2 miles. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product.

Where a unit on an estate such as Eastfield Industrial Estate, which lies east of Penicuik, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. Residences at universities like University of Edinburgh - Easter Bush Campus, 2.2 miles to the north of Penicuik, have compartment walls that must be resealed whenever services change.

Penicuik is about 8 miles south of Edinburgh, in Midlothian. We cover Penicuik, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Penicuik is one of 34 places in Midlothian on our list for service penetrations. Sites around Edinburgh have their own page, about 8 miles away.

We cover the EH26 postcode districts. Among the streets we cover are Windsor Square, High Street and The Square.

Leave it or put it right?

A seal that doesn’t match its tested detail gives false comfort. Correcting it means cutting it out and starting again with the specified product, so it makes sense to get it right first time. A leaking joint can damage finishes, stock and fittings inside. Early action limits what needs repairing.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Why appoint us

  • Fixed quotes based on photographs, drawings or a visit
  • Fully insured
  • Constructionline member for supplier checks
  • Failed material removed, not covered up

Work for main contractors and building owners

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Penicuik can form part of a wider programme.

FAQs: Penicuik

Can you work on a hospital site such as Rosslynlee Hospital?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Do you work on fire-rated sealing in hotels in Penicuik?

Yes. We install fire-rated and intumescent sealant where it is specified. Each seal follows the tested detail, and rooms are done in turn.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.

Which sealant will you use?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

What hours do you work?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

Do you guarantee your work?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

How the job changes by surface

Plastic pipes

Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail, and we will never swap a specified collar for sealant.

Masonry and concrete

Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening, so the sealant and any backing sit properly.
