Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
From enquiry to sign-off
Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use. Rural sites near Foster Street may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- First we go through the drawings, schedule or specification for the seals.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Getting the site ready
- Have the specification and drawings to hand
- For older buildings, check the asbestos register before work
- Send your site hours and access windows

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

About our fire stopping in Foster Street
Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it. Where there isn’t one, the designer or fire engineer needs to set one first. We work on cable penetrations, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors, and the usual reasons a site gets in touch are seals disturbed by maintenance and left open and unsealed penetrations discovered above suspended ceilings. One point of contact handles commercial sealant work in Foster Street from the first photos to the final walk-round, whether it’s one building or several.
For a smaller site near Foster Street, we plan to do all the penetrations in one go, with the specification and photographs sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Site staff or a sealant specialist?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
When something else is needed
Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:
- Deciding what a wall or floor needs, which belongs to the designer
- Large openings beyond what any sealant detail covers
- Signing off or certifying a building’s fire stopping
Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we will tell you honestly.
What we seal
- Pipe penetrations
- Joints between fire-resisting walls and floors

How the quote is worked out
There’s no standard rate for sealant work, because every site is different. What we look at:
- Site requirements such as inductions and permits
- Specialist products, such as fire-rated or hygienic sealants
- Access and working height
- The total length or number of joints
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
What we need to price the job
To price the job accurately, we need a clear picture of the site. Send us:
- The asbestos register, for older buildings
- Where the site is, with the postcode
- Access details, including height
- What the building is and how it’s used
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
What the job involves on each surface
Risers and ceiling voids
Voids hide a lot of unsealed openings. We work through the areas on your schedule methodically and tell you about openings outside the list.
Linear joints
Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement, along the full length of the run.
Commercial clients in Foster Street
We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.
Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
Your questions answered
Is Foster Street too small for you to travel to?
Not at all. Foster Street is within our area. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
Will you plan work around the academic year at somewhere like Harlow College?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Can the sealant be colour-matched?
That depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
Does weather matter for sealant work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Is sealant suitable for all service openings?
No. Each fire-rated sealant is tested for particular services, gap sizes and substrates. Outside that, a different product is needed, as set out by the designer.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
Compartments and services around Foster Street
Foster Street is about 21 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product. Foster Street is part of, or right next to, Harlow, which was built as a planned town. Buildings from the planned-town era have been rewired and replumbed over the years, and each change may have left gaps in fire-resisting walls.
Office fit-outs on sites such as Hastingwood Business Centre (to the south of Foster Street) add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. Theatres, wards and plant rooms at sites like Princess Alexandra Hospital, 3 miles west of Foster Street, all have compartment walls crossed by services. In a building such as Church of All Saints, any service penetration through a fire-resisting wall should be sealed to the specified detail.
Foster Street is about 2 miles east of Harlow, in Essex. We cover commercial sites throughout Foster Street. Our Essex coverage takes in 644 places. London is covered too, around 21 miles from Foster Street.
