Your questions answered
Will you plan work around the academic year at somewhere like Buckinghamshire New University?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Is a smaller place like Holmer Green outside your area?
Not at all. Holmer Green is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Will fire-rated sealant work on every penetration?
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.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Do you take on small jobs?
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.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.
What will the job cost?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we’ll price it properly.
About our fire stopping in Holmer Green
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. We use sealant where it is the specified product, and we tell you when a detail calls for something else. If you’re dealing with snag lists that include open service penetrations and unsealed joints where partitions meet the slab, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: in Holmer Green, that means joint design, primers and backing rod as standard.
In places the size of Holmer Green, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Why it’s worth doing now in Holmer Green
An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail, and doing it once, properly, is cheaper. In a smaller place such as Holmer Green, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
Pricing service penetrations depends on how many there are, their condition and the access, plus any specification you’re working to. Ask us for a fixed quote.

Should maintenance staff do it?
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Signs you need fire stopping in Holmer Green
Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.
Most enquiries start with something like this:
- Hidden openings found during inspections
- Openings left by services added after handover
- Fire-stopping items raised at inspection or handover
- Fire stopping installed outside its tested range
Campus buildings at universities such as Buckinghamshire New University, 2.5 miles north-east of Holmer Green, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.
What to look for in a quote
- Can the work be phased to keep areas open?

When something else is needed
Honesty saves time and money. New sealant won’t cure:
- Issuing fire ratings or certificates for seals
- Writing the fire-stopping specification
- Fire doors, dampers or other fire safety equipment

Where services cross fire walls in Holmer Green
At about 28 miles from central London, Holmer Green is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. Our part stays the same: the specified product, installed to its tested detail.
Holiday works at schools like Holmer Green Senior School often leave service openings to seal before pupils return. For a hospital such as The Chiltern Hospital, 1.8 miles north of Holmer Green, penetration sealing is normally phased ward by ward, with infection-control rules agreed first.

What the job involves on each surface
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail, so we check each one.
Risers and ceiling voids
Service risers and the voids above ceilings are where openings collect. Access is often tight, so we agree it with you in advance.

Our process
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. What matters most for a job in Holmer Green is a clear list of what needs doing, so send photos of each area. You will then get a fixed price for the work.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Preparing the site
- Tell staff and tenants when we will be in
- Flag any permit to work we will need
- Move anything stored against the joints
