Fire stopping across Charleston
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Our process
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Work on a big city site in Scotland usually involves inductions and permits. Pass on the site’s contractor rules when you get in touch.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- Completed areas are checked with you, with the records agreed when we quoted.
Before we start on site
- Warn occupants and staff about the work
- Tell us what induction or permit system the site runs
- Tell us which areas need to stay in use

Advice
How we handle fire stopping in Charleston
Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it, matching the product and detail it names. With no specification in place, the first step sits with your designer or fire engineer, not with us. We work on service gaps in risers, joints between fire-resisting walls and floors and linear gaps at wall heads, and the usual reasons a site gets in touch are expanding foam used as fire stopping and snag lists that include open service penetrations. Looking for mastic applicators who cover Charleston? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Older stone and tenement buildings in Scotland’s cities have typically been re-serviced many times. Wall type and service type decide the product, so both are checked before sealing.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

When something else is needed
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:
- Plastic pipes whose detail calls for a collar or wrap
- Issuing fire ratings or certificates for seals
- Fire doors, dampers or other fire safety equipment
Not sure which it is? You can give us a call on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.
Joints and surfaces we work on
- Pipe penetrations
- Service gaps in risers
- Cable penetrations
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
Commercial clients in Charleston
For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
Different surfaces, different methods
Masonry and concrete
Block walls and concrete floors are common substrates for penetration seals. Dust and loose debris are cleared out of the opening, with backing added if the detail requires it.
Plastic pipes
Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail, though larger ones normally call for a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.
Fire-rated sealing for Charleston buildings
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, and products should be tested for their end use. Our part is installing the specified fire-rated sealant to its tested detail. There are six care or nursing homes within about 2 miles of Charleston. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail.
Tenant changes at centres like Kingsway West Retail Park, 1.7 miles east of Charleston, often mean new services through walls between units. Wherever services are added at a hospital such as Ninewells Hospital, 0.7 miles to the south of Charleston, the compartment line has to be made good with the specified product. Colleges such as Dundee and Angus College - Kingsway Campus, 2.4 miles east of Charleston, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.
Charleston is about 2 miles west of Dundee, in Dundee. Any commercial site in Charleston is covered. 28 places across Dundee fall within our area, including Charleston.
Anyone looking for fire stopping in DD2 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. Streets here include Liff Road, South Road and Dunholm Road. We also cover Menzieshill (1 mile south), Dryburgh (1 mile north-east), Ninewells (1 mile south), Gowrie Park (1 mile south-west) and Camperdown (1 mile north) for service penetrations. Bigger towns within reach include Broughty Ferry (7 miles east), Stobswell (3 miles east), Barnhill (7 miles east), Pitkerro (4 miles east), Whitfield (4 miles east) and Woodside (3 miles east).
Landmarks near Charleston
Locally, jobs take us to sites close to Cox Branch Library and Balgay Hill and the streets around them. The nearest railway station is Invergowrie station, roughly 1.4 miles south-west. Other landmarks nearby include Overgate Centre (2.6 miles east) and Dudhope Castle (2.1 miles east). For a walk, there’s Balgay Hill and Piperdam Loch.
Should maintenance staff do it?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
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. A poor seal in places like these tends to cost more to put right later.
Charleston: questions and answers
Would you work within a site like Ninewells Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Does your area include sites such as Wester Gourdie Industrial Estate, near Charleston?
Yes. Our area takes in Charleston and its surroundings, with estates and business parks such as Wester Gourdie Industrial Estate included. A few photos and the unit address let us price the work.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Do you offer coloured sealant?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Do you take on multi-site work?
Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
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, so check your contract first. If it doesn’t require one, we can install the specified fire-rated sealant to its tested detail.
Maintenance after handover
Regular inspection catches problems early. Specifically:
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Foam or ordinary sealant is never a fire-seal repair
- Treat an open penetration as a priority repair
- Agree the fire-stopping specification before services go in
Don’t patch a fire-rated seal with anything outside its tested detail. A repair should use the original product, installed the same way unless the designer specifies otherwise.
On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts, and installation follows the programme.
