What affects the price in Pimlico
These are the things that shape the price:
- Which sealant the job calls for
- Removal of failed or old sealant
- The size and state of each joint
- Distance, for remote addresses
What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.
What we need to price the job
We can often quote from photographs and a few details. Please tell us:

- Anything awkward about access or site hours

Fire stopping for commercial buildings in Pimlico
Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, often unnoticed. We close the openings listed on your schedule, using the specified sealant and detail. Site teams most often ask us about head-of-wall gaps with no fire seal and fire stopping installed outside its tested range, across pipe penetrations, joints between fire-resisting walls and floors and linear gaps at wall heads. One point of contact handles commercial sealant work in Pimlico from the first photos to the final walk-round, whether it’s one building or several.
Barn and farm-building conversions near places like Pimlico 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.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Your questions answered
What happens to BS 476 references for fire stopping in Pimlico?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Do you cover business parks and estates near Pimlico, such as Kings Park Industrial Estate?
Yes, sites like Kings Park Industrial Estate are within our area, along with the rest of Pimlico. Photos and a short description are enough for a first look.
Does weather matter for sealant work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
How do we ask for a quote?
You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or email a schedule or drawings. Include photos or drawings if you have them.
Will you just go over the old sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Is your workmanship covered by a guarantee?
Yes. Workmanship is guaranteed for 12 months on every job.
Can the sealant be colour-matched?
It depends on the product. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.
General trades versus a specialist
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
From enquiry to sign-off
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. If others near Pimlico need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Mineral wool or other backing is fitted where required.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Preparing the site
- Point out parking and an unloading spot
- Point out any areas we must not close
- Tell us what induction or permit system the site runs
Getting a fixed quote
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
Advice
What the job involves on each surface
Metal pipes
Heat travels along metal pipework. We follow whatever the detail requires and flag anything we can’t match.
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes, though larger ones typically call for a collar or wrap. We check the pipe material and diameter against the detail before we start.

What else we do in Pimlico
Why act early in Pimlico
Open penetrations multiply: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small, rather than turning into a full building survey and reseal. Around Pimlico, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Compartments and services around Pimlico
For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. Our part stays the same: the specified product, installed to its tested detail. There are several hotels within about 2 miles of Pimlico. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product.
Older community buildings such as Church of the Ascension that have been rewired or given new heating can have service gaps through walls worth checking against the specification. Tenant changes at centres like The Heights Shopping Centre (2.9 miles north-west of Pimlico) often mean new services through walls between units. On estates like Kings Park Industrial Estate, 1.6 miles to the south-west of Pimlico, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.
