Fire stopping in Mill Green
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Different surfaces, different methods
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on and we confirm each before sealing.
Drylining partitions
Service holes through plasterboard are frequently oversized or ragged. An oversized hole may be outside the sealant’s range.
About our fire stopping in Mill Green
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We hold no third-party fire-stopping installer certificate and we’d rather say that up front. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. Most enquiries involve unsealed openings around new pipes and cables and builders’ foam or ordinary silicone in compartment walls, across joints between fire-resisting walls and floors, pipe penetrations and linear gaps at wall heads. A specialist sealant contractor works differently from a general builder: on jobs in Mill Green, preparation and product choice get the time they need.
Barn and farm-building conversions near places like Mill Green 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, in Mill Green as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Questions about Mill Green
Is New Greenham Business Park, near Mill Green, within your area?
Yes. We cover Mill Green and the area around it, including industrial estates, business parks and retail parks such as New Greenham Business Park. Photos and a short description are enough for a first look.
Is a smaller place like Mill Green outside your area?
Not at all. Mill 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.
Will fire-rated sealant work on every penetration?
No. A sealant’s evidence covers set services, gaps and wall or floor types. If an opening falls outside, it needs another solution.
How many days will you need on site?
It depends on the scope, but the work normally takes a single visit for a short list of penetrations, or a phased programme for a whole building. Larger or phased jobs take longer, and we will give you a timescale with the quote.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, ring 01277 525 020 or email drawings and photos. Include photographs or drawings if you have them.
Can you tell us what fire stopping our building needs?
No, that isn’t our role. Once you have a specification, we can price and install the sealant elements of it, and tell you if a detail needs another product.
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. Jobs in and around smaller places like Mill Green are normally planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.
- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Preparing the site
- Send your site hours and access windows
- Send any specification or drawings in advance
- Tell us which areas need to stay in use

Related advice
Do you need fire stopping in Mill Green?
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint. The tested detail for a linear joint states the width and movement it covers.
Most enquiries start with one or more of the following:
- Fire stopping installed outside its tested range
- Damaged fire seals in risers and voids
- Unsealed penetrations discovered above suspended ceilings
- Fire sealant pulled out of the opening
Large healthcare estates like West Berkshire Community Hospital (3.6 miles north-west of Mill Green) change their services often, so penetration seals are worth checking after M&E work.
Questions to ask before you book
- What the guarantee covers, and for how long
- Whether primer will be used where the manufacturer specifies it
- Whether old or failed sealant will be cut out, not overlaid
- Is the sealant right for the movement and the substrate?
Fire stopping around Mill Green: how the place shapes the job
Mill Green is about 50 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal. Fire stopping of openings and penetrations in England falls under Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.
For a building such as Church of St Peter, new heating or data runs are the usual reason penetrations need sealing. Holiday works at schools like Cheam School often leave service openings to seal before pupils return.
Mill Green is about 3 miles south of Thatcham, in Hampshire. We cover Mill Green and the rest of Hampshire, with the same fixed quotes and 12-month guarantee as everywhere else. Mill Green is one of 723 places in Hampshire on our list for service penetrations. For work in that direction, see our Reading page, about 13 miles away.

Landmarks near Mill Green
In Mill Green, that means premises near New Greenham Park and The Travellers Friend pub, among other places. For rail, the closest station is Thatcham station, roughly 2 miles north. Nearby you’ll also find Old Chapel Textile Centre (1.7 miles west) and West Berkshire Community Hospital (3.6 miles north-west). Not far away are Ladle Hill and Thatcham Reed Beds.
Why deal with it now?
Fire stopping is a regular point raised at inspections and handover. Late discoveries can delay handover while openings are reopened and resealed, so earlier action pays back. Older rural buildings around Mill Green move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Cost factors for service penetrations
Before we quote, we look at:
- Whether the work must be split into stages
- Access and working height
- The total length or number of joints
- Site requirements such as inductions and permits
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.
What to include in your enquiry
Diagnosis starts before we arrive. Tell us:
- A wide shot and a close-up of the area
- Any dates the work must fit around
- Anything awkward about access or site hours
- Any specification or named product
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
