How we handle fire stopping in Spencers Wood
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. 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. We work on small duct penetrations where the tested detail allows, pipe penetrations and joints between fire-resisting walls and floors, and what we’re called in for most is service penetrations left open after M&E works and open linear gaps along the top of fire-resisting walls.

Around Spencers Wood, penetration and linear seals tend to be one-building jobs. With the specification and photographs of the gaps, we can give a fixed quote and bring the right products.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Owners, agents and contractors
Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
After the work
Keep the joints in good shape with a few simple steps:
- Agree the fire-stopping specification before services go in
- Don’t let anyone top up a fire seal with the wrong product
- Keep product data and details in the fire safety file
- Check risers and ceiling voids after each round of works
Once the seals are in, tell other trades they exist and must not be disturbed. If a seal has to be opened for a new service, it should be reinstated to the same detail using the same product.
A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, which saves guesswork.
From enquiry to sign-off
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. What matters most for a job in Spencers Wood is a clear list of what needs doing, so send photos of each area. You’ll then get a fixed price for the work.
- The specification and schedule come first, so we know which details apply.
- 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 first.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
What we need from you
- Agree which areas must stay open
- Share the asbestos register for older buildings
- Share your working hours and any access restrictions

Fire stopping in Spencers Wood: the local picture
Spencers Wood is about 38 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls. 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. Either way, we install the specified product to its tested detail.
Where a unit on an estate such as Heron Industrial Estate, 0.6 miles south of Spencers Wood, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. Halls and meeting rooms at places like St Michael and All Angels sometimes gain new services, and any compartment wall crossed needs the specified seal.

What we are called out for in Spencers Wood
Damage plays a part too. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe, and the repair is often skipped.
Site and facilities staff are often the first to spot these:
- Builders’ foam or ordinary silicone in compartment walls
- Hidden openings found during inspections
- Service penetrations left open after M&E works
- Head-of-wall gaps with no fire seal
Wherever services are added at a hospital such as Royal Berkshire Hospital (to the north of Spencers Wood) the compartment line has to be made good with the specified product.

Doing it in-house
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 where general trades tend to cut corners.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Questions about Spencers Wood
Can you seal penetrations in a hotel in Spencers Wood after a refit?
Yes, to the specification and the product’s tested detail. We match the product to the wall or floor and the services, and say if something other than sealant is needed.
Could you schedule work at a campus like University of Reading - Whiteknights Campus for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
How do I request a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
Will you come and look before quoting?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs usually get a visit.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.
What affects the price in Spencers Wood
The price varies from site to site. It mainly depends on:
- How accessible the joints are
- Working within restricted access windows
- How much there is to seal
- Induction, permit and paperwork requirements
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Details that help us quote
To price the job accurately, we need to understand the site. Send us:
- Your programme or deadline
- Anything awkward about access or site hours
- What the building is and how it’s used
- Rough lengths or quantities, or drawings if you have them
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call 01277 525 020 or email drawings and photos.
