Your questions answered
Is Hirst too far out for you?
No. Small places get the same service as large ones. We cover the whole of Scotland. We plan jobs in smaller places so return trips are kept to a minimum.
Does your area include sites such as Harthill Industrial Estate, near Hirst?
Yes. We cover Hirst and the area around it, including industrial estates, business parks and retail parks such as Harthill Industrial Estate. Photos and a short description are enough for a first look.
Do you seal openings left by new services?
Yes. Send the schedule or marked-up drawings and the specified product details for a fixed quote. Work can run area by area behind the M&E trades so areas aren’t left open.
Will you sign off the seals for us?
No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. We work to the specification and the manufacturer’s installation guidance, and any records you need can be confirmed with the quote.
Are you members of a third-party fire-stopping installer scheme?
No. We don’t hold a third-party fire-stopping installer certificate. We are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded. Where a client or main contractor requires a scheme member, we’ll say so right away rather than waste your time.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, with one point of contact.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
About our fire stopping in Hirst
Most of our fire stopping work happens after the building is up. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, and they are easy to forget. Those on your schedule are closed with the specified product. If you have damaged fire seals in risers and voids and non-fire-rated filler around services, we can put it right. Searching for sealant specialists in Hirst? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Travel to smaller places like Hirst is planned so every penetration is sealed on one trip. Photos of the gaps, the services and the wall or floor type help us bring the right products.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

On site: what to expect
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs near Hirst are often grouped with others in the same area. Let us know if your dates have any give.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
- We gun the sealant in to the specified depth around each service and tool it.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Preparing the site
- Point out any areas we must not close
- Clear stock, furniture or equipment away from the joints
- Tell staff and tenants when we’ll be in

For managing agents and facilities managers
We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
How the quote is worked out
Before we quote, we look at:
- Which sealant the job calls for
- How much existing material needs removing
- Location, for remote and island sites
- The site’s rules and procedures
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
Sending details for a quote
Good information means a firmer quote. Helpful details to send:
- Access details, including height
- Where the site is, with the postcode
- Your programme or deadline
- Rough lengths or quantities, or drawings if you have them
For a fixed quote, give us a call on 01277 525 020 or send photos by email. You can also send details through our quote form.
Signs you need fire stopping in Hirst
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint, and the wrong product can split as a result. The tested detail for a linear joint states the width and movement it covers.
Look out for the following:
- Fire-rated sealant that has cracked or shrunk back
- Seals that don’t match their tested detail
- Non-fire-rated filler around services
- Openings found when ceilings come down for a refit
Large healthcare estates like Cleland Hospital (4.9 miles south-west of Hirst) change their services often, so penetration seals are worth checking after M&E work.
Questions to ask before you book
- Will RAMS and insurance details be available?
- How joint depth will be controlled
- Which product they’ll use, and why it suits the joint
- Whether old or failed sealant will be cut out, not overlaid
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, including keys, permits and any isolations.
Linear joints
Head-of-wall gaps, slab edges and wall junctions are linear joints. 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.
Other services in Hirst
After the work
A few simple habits keep the new joints working:
- Put resealing into every M&E and fit-out package
- Report damaged or disturbed seals as soon as they’re spotted
- Include service cupboards in routine inspections
- Leave fire sealant to cure fully before covering it
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, so check the product data first.
On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and installation follows the programme.
Fire stopping in Hirst: the local picture
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, with products tested for that end use. We install what’s specified, to the product’s tested detail.
On estates like Harthill Industrial Estate (1.9 miles east of Hirst), the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.
