FAQs: Portlethen
Will you plan work around the academic year at somewhere like Robert Gordon University?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Will you take on work at estates like Portlethen Retail Park, close to Portlethen?
Yes, sites like Portlethen Retail Park are within our area, along with the rest of Portlethen. To start, just phone 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Is sealant suitable for all service openings?
No. Sealant is the right product only where the tested detail says so. Collars, wraps, batts and boards exist for openings sealant doesn’t cover.
What does an EI 60 rating mean?
The tests are BS EN 1366-3 for penetrations and BS EN 1366-4 for linear joints, and classification is to BS EN 13501-2. EI 60 means integrity and insulation for 60 minutes in the tested arrangement; installing to the detail is what carries that across to site.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Fire stopping in Portlethen
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal, not a rule of thumb. We work on service gaps in risers, cable penetrations and pipe penetrations, and what we are called in for most is fire-stopping items raised at inspection or handover and seals that don’t match their tested detail. A single leaking joint is often how a building in Portlethen first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places such as Portlethen, 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 covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Penetration seals near Portlethen
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, using products tested for the way they’re used. We install fire-rated sealant to that tested detail where it is specified.
Residences at universities like Robert Gordon University, 3.9 miles to the north of Portlethen, have compartment walls that must be resealed whenever services change. For a building such as Portlethen Parish Church, new heating or data runs are the usual reason penetrations need sealing.

What else we do in Portlethen
What happens if it’s left?
An unsealed opening affects more than fire safety: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first. For buildings near Portlethen, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Advice
Commercial clients in Portlethen
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Signs you need fire stopping in Portlethen
Openings in fire-resisting walls typically appear when services are added or changed. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser can leave the hole behind. Across several fit-outs, the openings add up.
These are often picked up first by site or facilities staff:
- Builders’ foam or ordinary silicone in compartment walls
- Open linear gaps along the top of fire-resisting walls
- Damaged fire seals in risers and voids
- Unsealed openings around new pipes and cables
Refits at places like Portlethen Retail Park (to the north of Portlethen) often reroute services through walls between units.

What sealant work can’t fix
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Construction that lacks the fire resistance the seal relies on
- Large openings beyond what any sealant detail covers
- Designing or specifying fire stopping, which sits with the designer or fire engineer
Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we’ll tell you honestly.
What we seal
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Cable penetrations
- Linear gaps at wall heads
- Service gaps in risers
When to bring in a specialist
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
