Fire stopping in Great Warley
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Different surfaces, different methods
Cables and cable bundles
Data cabling added after handover is a regular cause of open service penetrations. We reseal around them to the specified detail, and any bundle too large for sealant alone is flagged.
Plastic pipes
Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail, though larger ones typically call for a collar or wrap. We check the pipe material and diameter against the detail before we start.
Fire stopping in Great Warley, done properly
It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance. We work on small duct penetrations where the tested detail allows, linear gaps at wall heads and cable penetrations, and what we’re called in for most is old intumescent sealant that has split away and builders’ foam or ordinary silicone in compartment walls. Facilities teams, main contractors and managing agents in Great Warley tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Barn and farm-building conversions near places like Great Warley often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

When to bring in a specialist
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.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Owners, agents and contractors
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
On site: what to expect
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. Jobs in and around smaller places like Great Warley are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Before we start on site
- Send any specification or drawings in advance
- Explain the parking and delivery arrangements
- Send asbestos survey details if the building is pre-2000
Getting a fixed quote
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, give us a call on 01277 525 020 or email the details over.

Penetration seals near Great Warley
Great Warley is about 18 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls. Great Warley has two care or nursing homes no more than 2 miles away. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail.
Hotels such as Brick House Hotel, 1.2 miles south-east of Great Warley, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. Office fit-outs on sites such as Warley Hill Business Park, 1 mile to the north-east of Great Warley, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. In a building such as St. Mary the Virgin, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Maintenance after handover
Cleaning and maintenance staff play a part too. Share these points with them:
- Have penetrations checked while they can still be seen
- Don’t let anyone top up a fire seal with the wrong product
- Leave fire sealant to cure fully before covering it
- Settle who seals which penetrations at the start of a project
Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original unless the designer specifies otherwise.
Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small compared with dozens found at once.
Why it’s worth doing now in Great Warley
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down, and the right detail can be checked at the time. For buildings around smaller places like Great Warley, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Pricing service penetrations depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.
