What happens if it’s left?
An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first. Failed sealant in a building in Primrose Hill can quickly affect neighbours, tenants or the floor below. Dealing with it early is simpler for everyone.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

How we handle fire stopping in Primrose Hill
On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings and the specified product data. Tell us what records you need and we’ll confirm with the quote. We work on cable penetrations, linear gaps at wall heads and small duct penetrations where the tested detail allows, and the usual reasons a site gets in touch are fire seals cut back for extra cables and never reinstated and fire-rated sealant that has cracked or shrunk back. Most enquiries from Primrose Hill start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
In a London area such as Primrose Hill, buildings are refitted often, and every new cable, pipe or duct through a fire-resisting wall or floor leaves a gap. Each service penetration gets fire-rated or intumescent sealant if that’s what is specified, laid to the product’s tested arrangement.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Service penetrations in Primrose Hill buildings
There are a good number of hotels within about 2 miles of Primrose Hill. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.
At a university such as Regent's University London, 1 mile south of Primrose Hill, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. In a retail centre such as O2 Centre, 1.1 miles north-west of Primrose Hill, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail.

How a job runs
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work typically takes anything from one day to a planned run of visits, depending on the number of seals and the access. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Old or wrong materials are cut out.
- 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.
Before we start on site
- Share your working hours and any access restrictions
- Tell us what induction or permit system the site runs
- Tell us which areas need to stay in use

Doing it in-house
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.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Cost factors for service penetrations
What shapes the price:
- Site requirements such as inductions and permits
- Which sealant the job calls for
- Distance, for remote addresses
- Quantities, in metres or numbers
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.
Details that help us quote
Diagnosis starts before we arrive. Let us know:
- The site address and postcode
- Clear photographs of the problem areas
- Rough lengths or quantities, or drawings if you have them
- What the building is and how it’s used

What we are called out for in Primrose Hill
Physical damage is another reason seals stop doing their job. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe.
Most enquiries start with something like this:
- Open linear gaps along the top of fire-resisting walls
- Improvised or mixed-product fire seals
- Builders’ foam or ordinary silicone in compartment walls
- Unsealed openings around new pipes and cables
Tenant changes at parks like Regis Road Business Park, 1 mile to the north-east of Primrose Hill, bring new data and services, and openings through fire-resisting walls need the specified seal.
What your quote should include
- What level of public liability insurance do they hold?
- Their approach to joint depth and backing
- Do they follow the manufacturer’s priming guidance?
- Will failed sealant be removed rather than covered?
Your questions answered
Does your area include sites such as Regis Road Business Park, near Primrose Hill?
Yes. We cover Primrose Hill and the area around it, including industrial estates, business parks and retail parks such as Regis Road Business Park. Photos and a short description are enough for a first look.
Do you work on fire-rated sealing in hotels in Primrose Hill?
Yes, where fire-rated sealant is the specified product. Each seal follows the tested detail, and rooms are done in turn.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
How long will the new sealant last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Is any job too small?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Do you work in Primrose Hill?
Yes. We cover Primrose Hill, and you can phone 01277 525 020 or email a schedule or drawings to get started.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
