Fire stopping across Winsor
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
From enquiry to sign-off
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and we clear our waste as we work. If others near Winsor need work, visits can be combined. A fixed quote is given before anything starts.
- We ask for the product and detail your designer has specified.
- 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.
- 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.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Let us know about inductions and permits
- Send asbestos survey details if the building is pre-2000

Fire stopping for commercial buildings in Winsor
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. Most enquiries involve snag lists that include open service penetrations and openings left by services added after handover, on cable penetrations, joints between fire-resisting walls and floors and pipe penetrations. Most enquiries from Winsor start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Smaller places such as Winsor still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
Fire-rated sealing for Winsor buildings
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. Either way, we install the specified product to its tested detail. There are a number of hotels within about 2 miles of Winsor. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.
For a unit at a centre such as Totton Shopping Centre, 2.8 miles east of Winsor, penetration seals are worth checking after each shop fit. Hotels such as The Bartley Lodge Hotel, 1.3 miles south-west of Winsor, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.
Winsor is about 2 miles west of Totton, in Hampshire. We cover commercial sites throughout Winsor, whether it’s a single job or part of a planned programme. We work across 723 places in Hampshire, from busy centres to rural villages. Our Southampton page has more on work in that area, about 7 miles away.
Business premises anywhere in SO40 are within our area. For a building on Winsor Road, Winsor Lane and Pound Lane or nearby, we can quote for service penetrations. If your building is just outside Winsor, we cover Copythorne (1 mile north-west), Bartley (1 mile south-west), Netley Marsh (1 mile south-east), Cadnam (1 mile west) and Newbridge (1 mile north-west). A short drive away, we cover Winchester (14 miles north-east), Eastleigh (9 miles east), Chandler's Ford (8 miles north-east), Hedge End (11 miles east), Lymington (12 miles south) and Romsey (6 miles north-east).
Near you in Winsor
Locally, jobs take us to sites close to Compass Inn and the streets around them. The nearest railway station is Ashurst New Forest station, about 2.7 miles south-east. A little further out are Tatchbury Mount Hospital (1 mile east) and Eling Experience (2.7 miles east). For a walk, there’s Copythorne Common.
Site staff or a sealant specialist?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Questions we’re asked in Winsor
Can you work at a site such as Mortimer Trading Estate, by Winsor?
Yes. Estates, retail parks and business parks around Winsor, Mortimer Trading Estate among them, are all within reach. To start, just give us a call on 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
Could you schedule work at a campus like Totton College for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Can you tell us what fire stopping our building needs?
No, we don’t design fire stopping. Once you have a specification, we can price and install the sealant elements of it and point out anything needing another product.
What will the job cost?
Each job is quoted on its own details. To get one, ring 01277 525 020 or send details through our quote form.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Can you reseal penetrations after our M&E works?
Yes. Share the penetration schedule and product details for a fixed quote. Work can run area by area behind the M&E trades.
Do you guarantee your work?
Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

Signs you need fire stopping in Winsor
Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. It may look closed, but it has no tested fire performance in that position, so it has to come out.
These are often picked up first by site or facilities staff:
- Openings left by services added after handover
- Penetration schedules that need working through
- Old intumescent sealant that has split away
- Head-of-wall gaps with no fire seal
For a site team at a college like Totton College, 1.9 miles east of Winsor, fire-rated sealing is best scheduled after the summer works.
