Cost factors for service penetrations
We price every job individually. The main factors are:
- Which sealant the job calls for
- Whether the work must be split into stages
- How much existing material needs removing
- The site’s rules and procedures
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.
What to include in your enquiry
To price the job accurately, we need to understand the site. Send us:
- The product your specification calls for
- Whether an asbestos survey exists
- Any dates the work must fit around
- The site address and postcode
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.
Fire stopping in Roxbourne, done properly
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. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance in Roxbourne and nearby. If you have snag lists that include open service penetrations and unsealed joints where partitions meet the slab, we can help. Looking for mastic applicators who cover Roxbourne? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we will confirm with the quote.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Leave it or put it right?
An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail. In a London building, a failed joint rarely affects only one party. Putting it right early is less disruptive than dealing with the consequences.
The price depends on the quantity of joints, how much old material needs removing and the access. Call for a fixed quote when you’re ready.

Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Ask which product is in place before decorating
- Include service cupboards in routine inspections
- Have penetrations checked while they can still be seen
- Flag new cables with no seal around them
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted.
Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small; found late, it can be one of many.
Work for main contractors and building owners
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Roxbourne can form part of a wider programme.
Fire-rated sealing for Roxbourne buildings
A 2-mile radius around Roxbourne takes in several hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. Every new tenant in a London building tends to bring new cabling, and with it new holes through compartment walls. We install fire-rated sealant where it is specified and work within the building manager’s permit system.
At a university such as Westminster University (2.6 miles east of Roxbourne), labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. At a healthcare site like Cygnet Hospital, which lies east of Roxbourne, new services through compartment walls are a constant, and each needs the specified seal. Colleges such as Christ the Redeemer College, 0.6 miles to the east of Roxbourne, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.
Roxbourne is about 1 mile east of Ruislip, in Greater London. Any commercial site in Roxbourne is covered. Roxbourne is one of 764 places we cover in Greater London for service penetrations. For work in that direction, see our London page.

From enquiry to sign-off
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses.

Questions about Roxbourne
Can work at a site such as Westminster University 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.
Will you take on work at estates like Victoria Retail park, close to Roxbourne?
Yes, sites like Victoria Retail park are within our area, along with the rest of Roxbourne. To start, just call the office on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Will you sign off the seals for us?
No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. Our part is fitting the specified product to its tested detail.
Can you seal any opening with fire-rated sealant?
No. Sealant is the right product only where the tested detail says so. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards, and we will tell you when that applies.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
How long does a job like this take?
The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.
Honest limits
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Fire doors, dampers or other fire safety equipment
- Walls or floors that aren’t fire-resisting to begin with
- Deciding what a wall or floor needs, which belongs to the designer
If in doubt, phone 01277 525 020 or send photos by email and we’ll say what we think before you book.
What we seal
- Pipe penetrations
- Service gaps in risers
