Your questions answered
Could you schedule work at a campus like Buckinghamshire New University for the vacation?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
What happens to BS 476 references for fire stopping in Prestwood?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
Is any job too small?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.
When can you be on site?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
How long does a job like this take?
It depends on the scope, but the work typically takes a single visit for a short list of penetrations, or a phased programme for a whole building. For bigger or phased jobs, we will set out a timescale with the quote.
About our fire stopping in Prestwood
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. The enquiries we see most involve unsealed joints where partitions meet the slab and non-fire-rated filler around services, across pipe penetrations, linear gaps at wall heads and joints between fire-resisting walls and floors. Whether you call it commercial sealant work, mastic application or joint sealing, in Prestwood it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around Prestwood, penetration and linear seals tend to be one-building jobs. Send the specification, drawings or photographs of the openings and we’ll quote to suit.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Where services cross fire walls in Prestwood
Fire stopping of openings and penetrations in England falls under 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. We install whatever has been specified, to the product’s tested detail. Prestwood lies roughly 31 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.
Halls and meeting rooms at places like Holy Trinity Church sometimes gain new services, and any compartment wall crossed needs the specified seal. In a school such as Prestwood Junior School, fire-rated sealant goes in around service penetrations where it is specified.
Prestwood is about 5 miles north of High Wycombe, in Buckinghamshire. Prestwood sits inside our coverage and the rest of Buckinghamshire, with the same fixed quotes and 12-month guarantee as everywhere else. 308 places across Buckinghamshire fall within our area, including Prestwood. For work in that direction, see our Reading page (20 miles or so).
Anyone looking for fire stopping in HP16 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee.

How a job runs
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Several jobs near Prestwood can be grouped on one trip. Mention the building’s opening times and we will work within them.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned first.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Preparing the site
- Let building users know which areas are affected
- Make sure the joints can be reached
- Have the specification and drawings to hand

What sealant work can’t fix
We check first that sealant really is the fix. It won’t put right:
- Writing the fire-stopping specification
- Fire doors, dampers or other fire safety equipment
- Approving the work on behalf of building control
Not sure which it is? You can ring 01277 525 020 or send photos by email and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Linear gaps at wall heads
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Cable penetrations
Should maintenance staff do it?
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Do you need fire stopping in Prestwood?
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.
Typical triggers for a call:
- Damaged fire seals in risers and voids
- Unsealed joints where partitions meet the slab
- Expanding foam used as fire stopping
- Hidden openings found during inspections
Residences at universities like Buckinghamshire New University (to the east of Prestwood) have compartment walls that must be resealed whenever services change.
What your quote should include
- Is the sealant right for the movement and the substrate?
- What the guarantee covers, and for how long
- Their public liability cover
- Whether primer will be used where the manufacturer specifies it
Looking after the joints
A few simple habits keep the new joints working:
- Have penetrations checked while they can still be seen
- Put resealing into every M&E and fit-out package
- Flag new cables with no seal around them
- File the specified details where the next contractor can find them
During planned inspections, look at seals in risers, cupboards and voids. Look for cracks, unsealed new cables and gaps that have been enlarged and get them dealt with.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job.
