Common questions from Titmore Green clients
Can you work on a hospital site such as Lister Hospital?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Is a smaller place like Titmore Green outside your area?
Not at all. Titmore Green is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
How many days will you need on site?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Is sealant suitable for all service openings?
No. A sealant’s evidence covers set services, gaps and wall or floor types. Outside that, a different product is needed, specified by your designer.
Do the same rules apply to fire stopping in Scotland?
Our area runs from Greater London and the South East to every part of Scotland. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook says service penetrations should keep at least the fire resistance of the wall or floor, with proprietary products tested for the end use.
Can you reseal penetrations after our M&E works?
Yes. Send the schedule or marked-up drawings and the specified product details. Work can run area by area behind the M&E trades keeping pace with the programme.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
About our fire stopping in Titmore Green
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. If you are dealing with hidden openings found during inspections and unsealed openings around new pipes and cables, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Titmore Green is the same: the right product in a properly prepared joint.
Rural conversions around Titmore Green can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
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.

How the quote is worked out
We price every job individually. The things that drive the figure:
- The total length or number of joints
- Access and working height
- Distance, for remote addresses
- Backing rod, priming and other preparation
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
What we need to price the job
The more we know, the firmer the quote. When you get in touch, include:
- The site address and postcode
- Anything awkward about access or site hours
- Drawings or a marked-up plan, if available
- Any dates the work must fit around
To get a fixed quote, call 01277 525 020 or send details through our quote form. Our quote form is another easy route.
Keeping the joints sound
Cleaning and maintenance staff play a part too. Share these points with them:
- Put resealing into every M&E and fit-out package
- Look above ceilings when tiles are lifted for other jobs
- File the specified details where the next contractor can find them
- Check with the data sheet before painting over fire sealant
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.
Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job.
From enquiry to sign-off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For work around Titmore Green, we aim to finish in one 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.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Getting the site ready
- Tell staff and tenants when we will be in
- Agree which areas must stay open
- Let us know about inductions and permits

Advice
Why it’s worth doing now in Titmore Green
An unsealed opening affects more than fire safety: smoke, noise and draughts pass through them every day. The specified fire seal closes the gap for all of these. Converted and older buildings near places like Titmore Green tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote when you are ready.

When to call us in Titmore Green
Damage plays a part too. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped and the opening isn’t always resealed.
Any of the following is a good reason to get the joints checked over:
- Builders’ foam or ordinary silicone in compartment walls
- Penetration schedules that need working through
- Fire seals cut back for extra cables and never reinstated
- Improvised or mixed-product fire seals
Hotels like Redcoats Farmhouse Hotel (to the west of Titmore Green) are refurbished in phases, and each phase can open up compartment walls.
What your quote should include
- How joint depth will be controlled
- Who will actually carry out the work
- Whether old or failed sealant will be cut out, not overlaid
- Health and safety accreditation such as CHAS
Penetration seals near Titmore Green
A 2-mile radius around Titmore Green takes in a number of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
On a site such as Horizon Technology Park (2.5 miles south-east of Titmore Green), every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product. Wherever services are added at a hospital such as Lister Hospital (to the east of Titmore Green) the compartment line has to be made good with the specified product.

Different surfaces, different methods
Linear joints
Head-of-wall gaps, slab edges and wall junctions are linear joints. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers and the installation has to fit inside those limits.
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail and we confirm each before sealing.
