How we handle fire stopping in Caversham
We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance on buildings around Caversham. If you have open linear gaps along the top of fire-resisting walls and service penetrations left open after M&E works, we can put it right, on small duct penetrations where the tested detail allows, pipe penetrations and linear gaps at wall heads alike. Searching for sealant specialists in Caversham? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
For a facilities manager in Caversham, fire-rated sealing tends to follow other work: a new data cabinet, a heating upgrade, a kitchen refit. Checking after M&E works is good practice, and we’ll seal what’s found where fire-rated sealant is the specified product.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What we can’t put right
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Walls or floors that aren’t fire-resisting to begin with
- Fire doors, dampers or other fire safety equipment
- Openings that need collars, wraps, batts or boards rather than sealant
Not sure which it is? You can phone 01277 525 020 or email the details over and we’ll tell you honestly.
Joints and surfaces we work on
- Service gaps in risers
- Linear gaps at wall heads
- Cable penetrations
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Pipe penetrations
Fire stopping in Caversham: the local picture
There are plenty of hotels within about 2 miles of Caversham. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Either way, we install the specified product to its tested detail.
For a hotel such as The Village Hotel, 1 mile to the south-west of Caversham, penetration seals are worth checking after any refit or services upgrade. For an estates team at a campus like University of Reading, 1.9 miles south of Caversham, summer M&E works are normally followed by a round of penetration sealing. On a hospital site such as Royal Berkshire Hospital, which lies south of Caversham, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

From enquiry to sign-off
Site rules come first: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. If you have more than one building in Caversham, they can often be done on the same visit, with one quote covering them. Tell us when the building is open and we will plan to suit.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
Getting the site ready
- Tell us your opening times and when work is allowed
- Confirm the product named in the specification
- Explain the parking and delivery arrangements

Advice
Doing it in-house
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.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Small ducts
Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products, and we’ll say if that applies.
Plastic pipes
Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail, though larger ones usually call for a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.
Why act early in Caversham
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. Many buildings in towns like Caversham have been extended or altered, and joints where old meets new tend to fail first. Renewing them before water gets in protects the fabric.
Pricing service penetrations depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

What sets the cost
There’s no standard rate for sealant work, because every site is different. What we look at:
- Removal of failed or old sealant
- Site requirements such as inductions and permits
- The total length or number of joints
- Working within restricted access windows
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
Before you send an enquiry
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- The postcode of the building
- Whether an asbestos survey exists
- The type of building and who uses it
- Drawings or a marked-up plan, if available
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. To get it moving, give us a call on 01277 525 020 or email us.
Questions we are asked in Caversham
Can work at a site such as University of Reading fit around teaching?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
How does the move away from BS 476 affect penetration seals in Caversham?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Can the sealant be colour-matched?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Can staff carry on working while you’re here?
Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.
