How we handle fire stopping in Sperberry Hill
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, ring 01277 525 020 or email drawings and photos with the schedule or marked-up drawings. Tell us what records you need and we’ll confirm with the quote. We work on cable penetrations, service gaps in risers and pipe penetrations, and the usual reasons a site gets in touch are improvised or mixed-product fire seals and damaged fire seals in risers and voids. One point of contact handles commercial sealant work in Sperberry Hill from the first photographs to the final walk-round, whether it’s one building or several.
Smaller places such as Sperberry Hill still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When it isn’t the sealant
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Writing the fire-stopping specification
- Openings that need collars, wraps, batts or boards rather than sealant
- Walls or floors that aren’t fire-resisting to begin with
Not sure which it is? You can give us a call on 01277 525 020 or send details through our quote form and we will tell you honestly before you book.
Surfaces we seal
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Service gaps in risers
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Cable penetrations
Signs you need fire stopping in Sperberry Hill
A common fault is a product that was never fire-rated in the first place: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it, so it has to come out.
Any of the following is a good reason to get the joints checked over:
- Penetration schedules that need working through
- Non-fire-rated filler around services
- Old intumescent sealant that has split away
- Unsealed openings around new pipes and cables
For a hotel such as Redcoats Farmhouse Hotel, 0.6 miles east of Sperberry Hill, penetration seals are worth checking after any refit or services upgrade.
Before you book anyone
- How they handle RAMS and site documents
- Whether primer will be used where the manufacturer specifies it
- Can the work be phased to keep areas open?
- Will CSCS-carded applicators be on site?
On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For work around Sperberry Hill, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- 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.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
What we need from you
- Move anything stored against the joints
- Let us know about inductions and permits
- Tell staff and tenants when we’ll be in

Related advice
Leave it or put it right?
Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first and the building feels the difference. One visit to deal with every failing joint makes more sense than several trips to a place like Sperberry Hill. Send photos of each area and we will quote for the lot.
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’ll have a fixed figure to work with.

- A Constructionline member, so easy to vet
- A fixed quote before work starts
- Work carried out by CSCS-carded applicators
- Public liability insurance in place
Keeping the joints sound
Problems stay small when the joints are checked regularly. Specifically:
- Don’t let anyone top up a fire seal with the wrong product
- Report damaged or disturbed seals as soon as they’re spotted
- Brief every trade that openings they make must be sealed
- File the specified details where the next contractor can find them
Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail using the same product.
Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.
What sets the cost
What shapes the price:
- Whether old sealant has to be cut out first
- Access and working height
- The product specified
- The total length or number of joints
What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote when you’re ready.
Before you send an enquiry
Whether it’s one area or a whole building, the same details help:
- Any dates the work must fit around
- The postcode of the building
- How the joints are reached, and at what height
- Asbestos survey details if the building is older
Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, call the office on 01277 525 020 or email drawings and photos.
Questions about Sperberry Hill
How does the move away from BS 476 affect penetration seals in Sperberry Hill?
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.
Will you plan work around the academic year at somewhere like North Hertfordshire College?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Can the building stay open while you work?
Normally, yes. Phased work can be planned so areas stay in use.
Do you offer coloured sealant?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.
How many days will you need on site?
We plan the time on site around your programme and access. You will have an expected duration 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.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
