Fire stopping across Blackfield
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Why act early in Blackfield
The longer openings stay, the more there tend to be: each new service adds to the list. Keeping on top of it after each round of works keeps the job small and avoids a much larger catch-up later. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.

How we handle fire stopping in Blackfield
We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on buildings around Blackfield. If you have expanding foam used as fire stopping and openings found when ceilings come down for a refit, we can help, whatever the surface. Searching for sealant specialists in Blackfield? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Converted and extended buildings around places like Blackfield can mix old and new construction, so it’s worth confirming the wall or floor type before choosing the seal. The right product depends on the wall or floor and the services passing through, and we’ll tell you if the detail calls for something other than sealant.
Whoever the client is, the cover is the same: 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.

Maintenance after handover
A few simple habits keep the new joints working:
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Ask the designer to confirm details early on refits
- Ask which product is in place before decorating
- Don’t let anyone top up a fire seal with the wrong product
Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.
Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.
On site: what to expect
We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. For a site in Blackfield, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- 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.
- 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.
- Completed areas are checked with you, with the records agreed when we quoted.
Preparing the site
- Agree which areas must stay open
- Tell staff and tenants when we will be in
- Arrange parking or a loading space
Ask for a quote
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Penetration seals near Blackfield
In England, Approved Document B covers fire stopping of openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.
In a school such as Blackfield Primary School, fire-rated sealant goes in around service penetrations where it is specified. Tenant changes at parks like Glenmore Business Park, 1.9 miles north-west of Blackfield, bring new data and services, and openings through fire-resisting walls need the specified seal. Hotels like Falcon Hotel, 1 mile north-east of Blackfield, are refurbished in phases, and each phase can open up compartment walls.

What sets the cost
These are the things that shape the price:
- The size and state of each joint
- Travel to remote or island sites
- Specialist products, such as fire-rated or hygienic sealants
- The total length or number of joints
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.
Before you send an enquiry
However big the job, the same details help:
- Rough lengths or quantities, or drawings if you have them
- What the building is and how it’s used
- Any specification or named product
- The site address and postcode
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to phone 01277 525 020 or email us with what you know.
Owners, agents and contractors
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
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.
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail, so we check each one.

FAQs: Blackfield
Is Blackfield too far out for you?
Not at all. Blackfield is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
What does the BS 476 change mean for fire-rated sealant in Blackfield?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
When can you be on site?
We are in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
Are you CHAS accredited?
Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.
Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How do I request a quote?
There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
Is the work guaranteed?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.
