About our fire stopping in Speedwell
No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow. We work on service gaps in risers, linear gaps at wall heads and cable penetrations, and what we’re called in for most is snag lists that include open service penetrations and service penetrations left open after M&E works. For commercial sealant work in Speedwell, you deal with one contact from quote to sign-off, whether it’s one building or several.
For a smaller site near Speedwell, we plan to do all the penetrations in one go, so send the specification and photographs first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
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.

Honest limits
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Approving the work on behalf of building control
- Gaps in walls that were never built as compartment walls
- Openings that need collars, wraps, batts or boards rather than sealant
If in doubt, call the office on 01277 525 020 or email drawings and photos and we’ll say what we think.
What we seal
- Cable penetrations
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads

What else we do in Speedwell
Surface by surface
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. The gap is measured at the widest point against the detail’s limits, and any outside it are raised with you.
Plastic pipes
Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail.
What sets the cost
Your fixed quote is built from the real scope. It takes account of:
- Travel to remote or island sites
- The size and state of each joint
- Removal of failed or old sealant
- How accessible the joints are
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
A few photographs plus some basic facts will normally do. Please tell us:
- When you need the work done
- Approximate linear metres or a joint schedule
- Anything awkward about access or site hours
- The asbestos register, for older buildings
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or email a schedule or drawings.
How a job runs
At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. For work around Speedwell, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- Completed areas are checked with you, with the records agreed when we quoted.
What we need from you
- Tell us what induction or permit system the site runs
- For older buildings, check the asbestos register before work
- Move anything stored against the joints

Advice
Penetration seals near Speedwell
Fire stopping of openings and penetrations in England falls under Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Speedwell has several hotels close by, all within 2 miles. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.
Hotels like The Bedford Arms Hotel, 0.5 miles north-west of Speedwell, are refurbished in phases, and each phase can open up compartment walls. Large healthcare estates like Bletchley Community Hospital (5.9 miles west of Speedwell) change their services often, so penetration seals are worth checking after M&E work.

FAQs: Speedwell
Can you seal penetrations in a hotel in Speedwell after a refit?
Yes, where the specification calls for fire-rated sealant. Each seal follows the tested detail, and rooms are done in turn.
Is Speedwell off your patch?
No. Places such as Speedwell are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work while the building is occupied?
In most cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.
How long will the new sealant last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Can you handle several sites?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
What happens if it’s left?
Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach. Around Speedwell, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we will quote for the lot.
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.

Signs you need fire stopping in Speedwell
Openings in fire-resisting walls normally appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser can leave the hole behind. Over a few years of fit-outs, a wall can collect a lot of these.
Clients usually get in touch after noticing something like this:
- Expanding foam used as fire stopping
- Open linear gaps along the top of fire-resisting walls
- Improvised or mixed-product fire seals
- Fire-stopping items raised at inspection or handover
In a school such as Woburn Lower School, fire-rated sealant goes in around service penetrations where it is specified.
