After the work
Keep the joints in good shape with a few simple steps:
- Arrange inspection before areas are covered up
- Check risers and ceiling voids after each round of works
- Keep general-purpose fillers away from compartment walls
- Put resealing into every M&E and fit-out package
During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown and get them dealt with.
On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.
Fire stopping in Windmill Hill
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We hold no third-party fire-stopping installer certificate and we’d rather say that up front. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. If you have improvised or mixed-product fire seals and expanding foam used as fire stopping, we can put it right, on linear gaps at wall heads, small duct penetrations where the tested detail allows and cable penetrations alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Windmill Hill it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
A job near Windmill Hill is usually planned around one visit, 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.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

FAQs: Windmill Hill
Is Windmill Hill off your patch?
Not at all. Windmill Hill is within our area. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
What does the BS 476 change mean for fire-rated sealant in Windmill 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. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Can you fit around our working hours?
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.
Is the work guaranteed?
Yes. Our workmanship is backed for 12 months.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Commercial clients in Windmill Hill
If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Windmill Hill can sit alongside others in a wider programme.
Why it’s worth doing now in Windmill Hill
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, and the right detail can be checked at the time. Converted and older buildings near places like Windmill Hill tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Signs you need fire stopping in Windmill Hill
Physical damage is another reason seals stop doing their job. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped, and the repair is often skipped.
Site and facilities staff are often the first to spot these:
- Snag lists that include open service penetrations
- Old intumescent sealant that has split away
- Service penetrations left open after M&E works
- Non-fire-rated filler around services
Schools such as Baynards Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.
What your quote should include
- Their pre-qualification and accreditations
- Will RAMS and insurance details be available?
- How they’ll work around occupants
- Will CSCS-carded applicators be on site?
What sealant work can’t fix
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Openings that need collars, wraps, batts or boards rather than sealant
- Approving the work on behalf of building control
- Fire risk assessments, a job for a competent assessor
If you are not sure, just ring 01277 525 020 or send details through our quote form and we’ll give you a straight answer.
Surfaces we seal
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Cable penetrations
- Service gaps in risers
How a job runs
Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Smaller jobs around Windmill Hill can be grouped with others nearby. You’ll have a fixed quote before work starts.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Preparing the site
- Have the specification and drawings to hand
- Tell us your opening times and when work is allowed
- Agree which areas must stay open
Ask for a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

Fire stopping in Windmill Hill: the local picture
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. Central London is about 42 miles from Windmill Hill. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.
Older community buildings such as Parish Church of All Saints (inworth) that have been rewired or given new heating can have service gaps through walls worth checking against the specification. For a building at a site such as Threshelfords Business Park, 1.8 miles to the north of Windmill Hill, a check of penetration seals after each fit-out is good practice.
