How we handle fire stopping in South Ham
Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail rather than guesswork. We work on cable penetrations, pipe penetrations and service gaps in risers, and the failures we’re asked to look at most are open linear gaps along the top of fire-resisting walls and builders’ foam or ordinary silicone in compartment walls. Whether you call it commercial sealant work, mastic application or joint sealing, in South Ham it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Buildings in a smaller place such as South Ham that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

After the work
Cleaning and maintenance staff play a part too. Pass these on to them:
- Foam or ordinary sealant is never a fire-seal repair
- Get seals inspected before ceilings and boxing close
- Agree the fire-stopping specification before services go in
- Look above ceilings when tiles are lifted for other jobs
Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.
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 installation follows the programme.

Questions about South Ham
Will you plan work around the academic year at somewhere like Basingstoke College of Technology?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you seal service penetrations in hotels around South Ham?
Yes, where the specification calls for fire-rated sealant. Each seal follows the tested detail, and rooms are done in turn.
Can weather delay the job?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Can you send site paperwork?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
How long will the new sealant last?
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.
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 if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Why deal with it now?
Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme which is why earlier is better. In a smaller place such as South Ham, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

Cost factors for service penetrations
These are the things that shape the price:
- The site’s rules and procedures
- Which sealant the job calls for
- How much there is to seal
- Phasing around occupants
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 and we will explain how it’s made up.
What to include in your enquiry
However big the job, the same details help:
- The site address and postcode
- A wide shot and a close-up of the area
- Anything awkward about access or site hours
- Approximate linear metres or a joint schedule
A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or speak to us on 01277 525 020 or email the details over to discuss it first.
Fire-rated sealing for South Ham buildings
Two care or nursing homes sit less than 2 miles from South Ham. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. There are plenty of hotels within about 2 miles of South Ham. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.
Colleges such as Basingstoke College of Technology, 0.8 miles to the north-east of South Ham, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. Hotels such as Great Western Hotel (to the north-east of South Ham) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. Halls and meeting rooms at places like Saint Peter's Church sometimes gain new services, and any compartment wall crossed needs the specified seal.

Honest limits
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Construction that lacks the fire resistance the seal relies on
- Openings that need collars, wraps, batts or boards rather than sealant
- Fire doors, dampers or other fire safety equipment
If in doubt, call the office on 01277 525 020 or send details through our quote form and we will say what we think before you book.
