Fire stopping for commercial buildings in Priddy's Hard

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on joints between fire-resisting walls and floors, service gaps in risers and cable penetrations, and the usual reasons a site gets in touch are fire sealant pulled out of the opening and fire seals cut back for extra cables and never reinstated. A single leaking joint is often how a building in Priddy's Hard first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

For a smaller site near Priddy's Hard, we plan to do all the penetrations in one go, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Penetration seals near Priddy's Hard

For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. We install whatever has been specified, to the product’s tested detail. Seven care or nursing homes sit less than 2 miles from Priddy's Hard. Where new services have gone through compartment walls in a care setting, the gaps need the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail.

Theatres, wards and plant rooms at sites like Gosport War Memorial Hospital (to the south-west of Priddy's Hard) all have compartment walls crossed by services. At a university such as University of Portsmouth - North Zone, 1.3 miles south-east of Priddy's Hard, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. Workshops and IT rooms at colleges like St Vincent College (0.5 miles south-west of Priddy's Hard) are re-serviced often, leaving penetrations to seal.

Priddy's Hard is about 1 mile east of Gosport, in Hampshire. If you’re looking for fire stopping in Priddy's Hard, we can help, as we do across Hampshire. Our Hampshire coverage takes in 723 places, large and small.

We also cover Forton (1 mile south-west), Elson (1 mile north-west), Gosport (1 mile west), Bridgemary (2 miles north-west) and Rowner (2 miles north-west) for service penetrations. Nearby towns on our patch include Havant (7 miles north-east), Eastleigh (15 miles north-west), Fareham (4 miles north-west), Horndean (9 miles north-east), Hedge End (11 miles north-west) and Waterlooville (7 miles north-east).

Different surfaces, different methods

Metal pipes

Metal pipes conduct heat, so their details often call for extra measures along the pipe, and the tested detail may ask for insulation beyond the wall. If the detail needs something beyond sealant, we tell you.

Drylining partitions

Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do.

FAQs: Priddy's Hard

Can you work in a care home near Priddy's Hard with residents in?

Yes. We work around residents’ routines, a room or two at a time. We follow the home’s own procedures throughout.

Is Cranbourne Industrial Estate, near Priddy's Hard, within your area?

Yes. Our area takes in Priddy's Hard and its surroundings, with estates and business parks such as Cranbourne Industrial Estate included. Photos and a short description are enough for a first look.

When is resealing likely to be due?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

How much does the work cost?

Each job is quoted on its own details. For yours, phone 01277 525 020 or use the quote form with a description of the work.

Is colour matching possible?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Is any job too small?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Is your workmanship covered by a guarantee?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Looking after the joints

After handover, a little attention goes a long way:

  • Arrange inspection before areas are covered up
  • Include service cupboards in routine inspections
  • Record which product was used where
  • Keep general-purpose fillers away from compartment walls

Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.

Keep a register of where seals are and what they are made of. It tells the next contractor exactly what to reinstate.

Building owners, agents and FMs in Priddy's Hard

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

We work for building owners and managing agents on everything from one building to a spread of sites around Priddy's Hard. One quote can cover more than one site, which keeps the paperwork simple.

Doing it in-house

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Why act early in Priddy's Hard

An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product. Older rural buildings around Priddy's Hard move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Pricing service penetrations depends on quantities, condition and access, and any specification that applies. Call for a quote.
