About our fire stopping in Downley
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal. We work on pipe penetrations, linear gaps at wall heads and small duct penetrations where the tested detail allows, and the failures we are asked to look at most are unsealed joints where partitions meet the slab and seals disturbed by maintenance and left open. For commercial sealant work in Downley, you deal with one contact from quote to sign-off, whether it’s one building or several.
Rural conversions around Downley can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Quoting for work in Downley
Before we quote, we look at:
- Whether the work must be split into stages
- Removal of failed or old sealant
- How accessible the joints are
- Travel to remote or island sites
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.
Sending details for a quote
It doesn’t need to be a full survey. These details are enough to start:
- Whether an asbestos survey exists
- Rough lengths or quantities, or drawings if you have them
- The site address and postcode
- How the joints are reached, and at what height

When to call us in Downley
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls and later need putting right.
Any of the following is a good reason to get the joints checked over:
- Penetration schedules that need working through
- Service penetrations left open after M&E works
- Seals disturbed by maintenance and left open
- Builders’ foam or ordinary silicone in compartment walls
At a university such as Buckinghamshire New University (Wycombe Campus), 1.6 miles to the south-east of Downley, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.
Before you book anyone
- Is the sealant right for the movement and the substrate?
- How joint depth will be controlled
- Their pre-qualification and accreditations
- Will RAMS and insurance details be available?
Our process
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. If others near Downley need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.
- The specification and schedule come first, so we know which details apply.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Before we start on site
- Tell us your opening times and when work is allowed
- Confirm the product named in the specification
- Arrange parking or a loading space
Quotes
Let us know the site, the scope and your timescale, and we will put a fixed quote together. To get it moving, call the office on 01277 525 020 or email us.

What else we do in Downley
What we can’t put right
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Deciding what a wall or floor needs, which belongs to the designer
- Signing off or certifying a building’s fire stopping
- Gaps in walls that were never built as compartment walls
If in doubt, call the office on 01277 525 020 or send details through our quote form and we’ll say what we think before you book.
What we seal
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Pipe penetrations
How the job changes by surface
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest so we know it sits within the tested range.
Drylining partitions
Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do and we will tell you what the detail says instead.
Fire stopping around Downley: points for this area
The area within 2 miles of Downley holds several hotels. In hotels, bedroom and corridor walls are typically fire-resisting, so services added in a refit need sealing with the specified product. 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. What we install is set by the specification, and it goes in to the tested detail.
For a hotel such as Buckingham Hotel (0.8 miles south of Downley), penetration seals are worth checking after any refit or services upgrade. For a building such as St. James the Great, new heating or data runs are the usual reason penetrations need sealing.
Downley is about 2 miles north-west of High Wycombe, in Buckinghamshire. Any commercial site in Downley is covered, for single jobs and planned programmes alike. Across Buckinghamshire, 308 places are covered, Downley among them. For work in that direction, see our Reading page (16 miles or so).
We take on service penetrations across the HP13 postcode area, for business premises of every kind. We cover commercial and managed buildings on Willoughby's Walk, Gray's Lane and West Court. Just outside Downley, we also work in Naphill (1 mile north), Hughenden Valley (2 miles north-east), High Wycombe (2 miles south-east), Terriers (2 miles east) and Four Ashes (2 miles east). Nearby towns on our patch include Aylesbury (12 miles north), Chesham (8 miles north-east), Marlow (5 miles south), Amersham (8 miles east), Beaconsfield (6 miles south-east) and Chalfont St Peter (10 miles east).
Around Downley
We work on buildings around The Royal Grammar School, Le De Spencers Arms and The Tower and the streets around them. Downley’s nearest station is High Wycombe station, about 1.8 miles south-east of the centre. Other landmarks nearby include High Wycombe Castle (1.6 miles south-east) and Eden (1.5 miles south-east). Not far away are Prestwood Local Nature Reserve.
Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. 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.
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.
Questions we’re asked in Downley
Is a hospital such as Wycombe General Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do you seal service penetrations in hotels around Downley?
Yes, where the specification calls for fire-rated sealant. We match the product to the wall or floor and the services, and say if something other than sealant is needed.
What’s the quickest route to a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.
Can you fit around our working hours?
We are 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.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
