Photos, a specification or a quick description of the joints is enough to start a fixed quote.
How we handle fire stopping in Greenlea
On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we’ll confirm with the quote. The enquiries we see most involve penetration schedules that need working through and expanding foam used as fire stopping, across small duct penetrations where the tested detail allows, pipe penetrations and joints between fire-resisting walls and floors. Searching for sealant specialists in Greenlea? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Travel to smaller places like Greenlea 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 our work fails within that year, we put it right.

Surface by surface
Small ducts
Some fire-rated sealant details cover small ducts. Bigger ducts and fire-resisting ductwork are normally handled with other products, and we’ll say if that applies.
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. The gap is measured at the widest point so we know it sits within the tested range.
Doing it in-house
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.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
What we can’t put right
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Reviewing a building’s overall fire safety
- Deciding what a wall or floor needs, which belongs to the designer
- Issuing fire ratings or certificates for seals
If you are not sure, just call 01277 525 020 or use the quote form and we’ll give you a straight answer.
What we seal
- Linear gaps at wall heads
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Cable penetrations
- Pipe penetrations
- Small duct penetrations where the tested detail allows
From enquiry to sign-off
Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. For a building near Greenlea, directions, keys and a contact on the day are worth sorting early. We’ll confirm the plan with the fixed quote.
- The specification and schedule come first, so we know which details apply.
- Access, permits and the order of areas are agreed with the site team.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Preparing the site
- Send any specification or drawings in advance
- Send asbestos survey details if the building is pre-2000
- Share your working hours and any access restrictions
Quotes
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
Advice
Compartments and services around Greenlea
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 what’s specified, to the product’s tested detail.
Residences at universities like Crichton University Campus (to the west of Greenlea) have compartment walls that must be resealed whenever services change. On a site such as Brasswell Office Park, which lies west of Greenlea, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product. Workshops and IT rooms at colleges like Dumfries & Galloway College - Dumfries Campus (to the west of Greenlea) are re-serviced often, leaving penetrations to seal.
Greenlea is about 4 miles east of Dumfries, in Dumfries and Galloway. Our applicators travel to Greenlea for work on service penetrations.

Greenlea: questions and answers
Could you schedule work at a campus like Crichton University Campus for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is Greenlea too far out for you?
No. Places such as Greenlea are covered as much as the big towns. We work across every Scottish council area. Where we can, we group nearby jobs to make the most of each trip.
Do you offer coloured sealant?
That depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.
Do you hold third-party fire-stopping installer certification?
No, and we won’t imply otherwise. Third-party schemes aren’t a legal requirement, but many clients and main contractors ask for them. Where it isn’t required, we install the specified sealant to the maker’s details.
Do you approve fire stopping for building control?
No. Approval sits with the designer, principal designer or building control. We will confirm the product and detail installed.
Can you seal any opening with fire-rated sealant?
No. It depends on the tested detail for that wall or floor and service. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards, and we’ll tell you when that applies.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
What happens if it’s left?
Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like Greenlea, a repair visit takes planning, so it’s better to act early.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
