Common questions from Charlton clients
Is Sunbury International Business Centre, near Charlton, within your area?
Yes. We cover Charlton and the area around it, including industrial estates, business parks and retail parks such as Sunbury International Business Centre. Send details of the unit and the work through our quote form for a quick quote.
How does the move away from BS 476 affect penetration seals in Charlton?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
How soon can the area be used again?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
How do we ask for a quote?
The quote form is the simplest route, though you can also ring 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.
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.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
How long does a typical visit take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Fire stopping in Charlton
A fire-rated sealant is only one part of a tested system: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and we say so if it doesn’t fit. The enquiries we see most involve head-of-wall gaps with no fire seal and openings left by services added after handover, on linear gaps at wall heads, small duct penetrations where the tested detail allows and cable penetrations. Facilities teams, main contractors and managing agents in Charlton tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Barn and farm-building conversions near places like Charlton often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Why deal with it now?
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. Older rural buildings around Charlton move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

Different surfaces, different methods
Drylining partitions
Plasterboard partitions are tested as a specific construction. The sealant detail has to be tested in that wall type, with the stated board layers first.
Small ducts
Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products.
Quoting for work in Charlton
A fixed quote reflects the actual work. It allows for:
- The site’s rules and procedures
- Backing rod, priming and other preparation
- Location, for remote and island sites
- Access and working height
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.
What we need to price the job
Whether it’s one area or a whole building, the same details help:
- Clear photos of the problem areas
- Approximate linear metres or a joint schedule
- Any specification or named product
- The postcode of the building
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, speak to us on 01277 525 020 or email drawings and photos.
After the work
Regular inspection catches problems early. Specifically:
- Settle who seals which penetrations at the start of a project
- Treat an open penetration as a priority repair
- Keep product data and details in the fire safety file
- Check risers and ceiling voids after each round of works
During planned inspections, look at seals in risers, cupboards and voids. Look for cracks, unsealed new cables and gaps that have been enlarged.
Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.
How a job runs
Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Charlton need work, visits can be combined. A fixed quote is given before anything starts.

Fire stopping around Charlton: what changes locally
Charlton is about 16 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. Our part stays the same: the specified product, installed to its tested detail.
For a building at a site such as Sunbury International Business Centre, 0.8 miles to the north-east of Charlton, a check of penetration seals after each fit-out is good practice. Halls and meeting rooms at places like Church of St Mary Magdalene sometimes gain new services, and any compartment wall crossed needs the specified seal. Hospital estates such as Ashford Hospital (2.6 miles north-west of Charlton) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
