Your questions answered
Which Scottish guidance covers penetration seals in Dornock?
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. Design sits with the designer and the verifier; installation to the tested detail is our part.
Can you take on a job at a hospital such as Annan Hospital?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
How many days will you need on site?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
About our fire stopping in Dornock
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. If you have expanding foam used as fire stopping and fire stopping installed outside its tested range, we can help, on cable penetrations, joints between fire-resisting walls and floors and pipe penetrations alike. Searching for sealant specialists in Dornock? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Around smaller places such as Dornock, 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.
Our 12-month guarantee is about workmanship, not 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.

Site staff or a sealant specialist?
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
What affects the price in Dornock
To price the job, we consider:
- Backing rod, priming and other preparation
- Location, for remote and island sites
- Specialist products, such as fire-rated or hygienic sealants
- Quantities, in metres or numbers
What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote when you’re ready.
Before you send an enquiry
We can often quote from photos and a few details. It helps to include:
- The product your specification calls for
- Clear photos of the problem areas
- Asbestos survey details if the building is older
- How the joints are reached, and at what height
Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, give us a call on 01277 525 020 or send photos by email.
Diagnose, treat, sign off
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, with the work itself normally taking anything from one day to a planned run of visits, depending on the number of seals and the access. For work around Dornock, we aim for one trip, so photographs, sizes and a full list matter. External joints need a dry spell as well.
- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out first.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Getting the site ready
- Point out any areas we must not close
- Tell staff and tenants when we’ll be in
- Flag any permit to work we’ll need

Advice
What the job involves on each surface
Masonry and concrete
Many seals are made in blockwork, brickwork or concrete slabs. Dust and loose debris are cleared out of the opening.
Cables and cable bundles
Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. Bundle size, cable type and the space between cables all matter, so we check before sealing.
What else we do in Dornock
Signs you need fire stopping in Dornock
A common fault is a product that was never fire-rated in the first place: builders’ foam or ordinary silicone used to fill a hole. The opening looks sealed but has no fire test evidence behind it.
Typical triggers for a call:
- Penetration schedules that need working through
- Hidden openings found during inspections
- Non-fire-rated filler around services
- Seals that don’t match their tested detail
Older community buildings such as Dornock Parish Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
Before you book anyone
- What the guarantee covers, and for how long
- Whether old or failed sealant will be cut out, not overlaid
- Will CSCS-carded applicators be on site?
- Will RAMS and insurance details be available?
What we can’t put right
Being straight saves everyone time. Fresh joints won’t solve:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Gaps in walls that were never built as compartment walls
- Plastic pipes whose detail calls for a collar or wrap
Not sure which it is? You can speak to us on 01277 525 020 or email us and we’ll tell you honestly.
Surfaces we seal
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
- Pipe penetrations
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Cable penetrations
Penetration seals near Dornock
In Scotland, clause 2.1.14 of the non-domestic Technical Handbook expects service penetrations to keep at least the fire resistance duration of the wall or floor, using products tested for the way they’re used. Where fire-rated sealant is specified, that’s what we install, to the tested detail.
Wherever services are added at a hospital such as Annan Hospital (2 miles west of Dornock) the compartment line has to be made good with the specified product. In a school such as Annan Academy, fire-rated sealant goes in around service penetrations where it is specified.
