Fire stopping for businesses in Westrigg
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
On site: what to expect
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Tell us who will meet us and how to get in at your building near Westrigg. That goes into the plan alongside the quote.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Before we start on site
- For older buildings, check the asbestos register before work
- Make sure the joints can be reached
- Tell us what induction or permit system the site runs
Getting a fixed quote
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to ring 01277 525 020 or email drawings and photos with what you know.

Fire stopping in Westrigg
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. The enquiries we see most involve unsealed openings around new pipes and cables and open linear gaps along the top of fire-resisting walls, across cable penetrations, joints between fire-resisting walls and floors and pipe penetrations. Facilities teams, main contractors and managing agents in Westrigg tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Around smaller places such as Westrigg, 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.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Maintenance after handover
Once the work is signed off, these steps help:
- Brief every trade that openings they make must be sealed
- Settle who seals which penetrations at the start of a project
- Don’t let anyone top up a fire seal with the wrong product
- Record which product was used where
Keep the product data and installation details with the building’s fire safety information. Anyone resealing later needs to know which product and detail were used.
Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.
Should maintenance staff do it?
Redoing a failed joint typically costs more than getting it right at the outset, 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.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Fire stopping in Westrigg: the local picture
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, and products should be tested for their end use. We install fire-rated sealant to that tested detail where it is specified.
On a hospital site such as Tippethill Hospital, 2.6 miles east of Westrigg, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. For a unit at a site such as Harthill Industrial Estate, 1.9 miles south of Westrigg, new power or data runs between office and warehouse can breach a compartment wall. Holiday works at schools like Armadale Academy often leave service openings to seal before pupils return.
Westrigg is about 4 miles west of Bathgate, in West Lothian. Commercial clients in Westrigg can call on us for service penetrations. Westrigg is one of 55 places we cover in West Lothian. Our Glasgow page has more on work in that area.
Work on service penetrations is covered throughout EH48. Buildings on Sunnydale Road, Craig Street and Sunnydale Drive are within our area for service penetrations. If your building is just outside Westrigg, we cover Blackridge (1 mile west), Greenrigg (2 miles south), Harthill (2 miles south), Eastfield (2 miles south) and Armadale (2 miles east). A short drive away, we cover Livingston (9 miles east), Bathgate (4 miles east), Linlithgow (8 miles north-east), Whitburn (3 miles south-east), East Calder (12 miles east) and Broxburn (11 miles east).

Westrigg: questions and answers
What do Scotland’s building standards say about service penetrations in Westrigg?
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. We install what has been specified, to the manufacturer’s tested detail, while design and approval sit with the designer and the verifier.
Can you work at a site such as Harthill Industrial Estate, by Westrigg?
Yes. Our area takes in Westrigg and its surroundings, with estates and business parks such as Harthill Industrial Estate included. A few photographs and the unit address let us price the work.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
How long will the new sealant last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It won’t put right:
- Approving the work on behalf of building control
- Gaps in walls that were never built as compartment walls
- Large openings beyond what any sealant detail covers
If you are not sure, just ring 01277 525 020 or email us and we’ll give you a straight answer.
Surfaces we seal
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Linear gaps at wall heads
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Service gaps in risers
How the job changes by surface
Metal pipes
Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on, so we check each one.
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed and the installation has to fit inside those limits.
