How a job runs
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. What matters most for a job in Lower Nazeing is a clear list of what needs doing. You’ll then get a fixed price for the work.
- 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.
- Unsuitable material is removed and the opening cleaned so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
What we need from you
- Send your site hours and access windows
- Flag any permit to work we’ll need

Advice
How we handle fire stopping in Lower Nazeing
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. We work on pipe penetrations, small duct penetrations where the tested detail allows and cable penetrations, and the usual reasons a site gets in touch are openings left by services added after handover and open linear gaps along the top of fire-resisting walls. One point of contact handles commercial sealant work in Lower Nazeing from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Around Lower Nazeing, penetration and linear seals tend to be one-building jobs. With the specification and photos of the gaps, we can give a fixed quote and bring the right products.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

What happens if it’s left?
An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

What sets the cost
We price every job individually. The things that drive the figure:
- How much there is to seal
- Site requirements such as inductions and permits
- Location, for remote and island sites
- Phasing around occupants
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
Details that help us quote
We can often quote from photos and a few details. Please tell us:
- Asbestos survey details if the building is older
- Your programme or deadline
- Specification clauses that apply
- Access details, including height
To get a fixed quote, call 01277 525 020 or send details through our quote form. Our quote form is another easy route.
Different surfaces, different methods
Small ducts
Ducts are only sealed with sealant where the detail allows it. The ductwork, its supports and any dampers are for the ductwork contractor.
Plastic pipes
Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail, and we’ll never swap a specified collar for sealant.

Other services in Lower Nazeing
Should maintenance staff do it?
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Questions we are asked in Lower Nazeing
Is hospital work, at somewhere like Princess Alexandra Hospital, something you do?
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.
Is Lower Nazeing too small for you to travel to?
Not at all. Lower Nazeing is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
How long do sealant joints last?
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.
Can you quote from photos?
It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Can you tell us what fire stopping our building needs?
No. The specification comes from your designer, fire engineer or building control. Our role is installing what they specify, to the product’s tested detail.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
When something else is needed
Before quoting, we check that sealant is the right answer. It won’t put right:
- Issuing fire ratings or certificates for seals
- Fire doors, dampers or other fire safety equipment
- Walls or floors that aren’t fire-resisting to begin with
Not sure which it is? You can phone 01277 525 020 or email the details over and we’ll tell you honestly.

- Cable penetrations
- Joints between fire-resisting walls and floors

Penetration seals near Lower Nazeing
Central London is about 17 miles from Lower Nazeing. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. We install whatever has been specified, to the product’s tested detail.
Schools such as Nazeing Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. Tenant changes at parks like Hilgrove Business Park (to the west of Lower Nazeing) bring new data and services, and openings through fire-resisting walls need the specified seal. For a hospital such as Princess Alexandra Hospital, 3.7 miles to the north-east of Lower Nazeing, penetration sealing is normally phased ward by ward, with infection-control rules agreed first.
