Fire stopping in Hartwell
Most of our fire stopping work happens after the building is up. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls. Those on your schedule are closed with the specified product. We work on small duct penetrations where the tested detail allows, pipe penetrations and service gaps in risers, and the usual reasons a site gets in touch are openings found when ceilings come down for a refit and fire sealant pulled out of the opening. Whoever orders the work in Hartwell, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
For a smaller site near Hartwell, we plan to do all the penetrations in one go, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.
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.

Fire-rated sealing for Hartwell buildings
A 2-mile radius around Hartwell takes in a number of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. Hartwell is about 39 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.
Colleges such as Buckinghamshire College Group, 1.4 miles to the north-east of Hartwell, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. Where a unit on an estate such as Bicester Road Industrial Estate, which lies north of Hartwell, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.
Hartwell is about 1 mile west of Southcourt, in Buckinghamshire. Our applicators travel to Hartwell for work on service penetrations. We work across 308 places in Buckinghamshire. For work in that direction, see our Oxford page (17 miles or so).

How a job runs
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Rural sites near Hartwell may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- We ask for the product and detail your designer has specified.
- We sort the openings by the detail each one needs.
- Old or wrong materials are cut out.
- Mineral wool or other backing is fitted where required.
- We gun the sealant in to the specified depth around each service and tool it.
- We walk the completed areas with you and confirm the records agreed at quote stage.
What we need from you
- Tell us what induction or permit system the site runs
- Tell us which areas need to stay in use
- Warn occupants and staff about the work
Getting a fixed quote
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Honest limits
Being straight saves everyone time. Fresh joints won’t solve:
- Issuing fire ratings or certificates for seals
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Gaps in walls that were never built as compartment walls
If you’re not sure, just phone 01277 525 020 or email us and we will give you a straight answer before you book.
What we seal
- Cable penetrations

Your questions answered
Can you seal penetrations in a hotel in Hartwell after a refit?
Yes, where fire-rated sealant is the specified product. Each seal follows the tested detail, and rooms are done in turn.
Is a smaller place like Hartwell outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Will you come and look before quoting?
It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
How long does a job like this take?
That varies with the scale of the job, though a typical visit usually takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. For bigger or phased jobs, we’ll set out a timescale with the quote.
How the quote is worked out
Each job is priced on its own details. The main factors are:
- The total length or number of joints
- How accessible the joints are
- Location, for remote and island sites
- The size and state of each joint
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
What to include in your enquiry
Whether it’s one area or a whole building, the same details help:
- The product your specification calls for
- Rough lengths or quantities, or drawings if you have them
- Clear photographs of the problem areas
- What the building is and how it’s used
Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to phone 01277 525 020 or email a schedule or drawings.

What else we do in Hartwell
Do you need fire stopping in Hartwell?
Physical damage is another reason seals stop doing their job. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe.
Things that typically lead to an enquiry:
- Builders’ foam or ordinary silicone in compartment walls
- Old intumescent sealant that has split away
- Unsealed openings around new pipes and cables
- Fire stopping installed outside its tested range
On a hospital site such as Royal Buckinghamshire Hospital, which lies north-east of Hartwell, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
What to look for in a quote
- Do they follow the manufacturer’s priming guidance?
- Will RAMS and insurance details be available?
- What the guarantee covers, and for how long
- Will CSCS-carded applicators be on site?
Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Brief every trade that openings they make must be sealed
- Settle who seals which penetrations at the start of a project
- Flag new cables with no seal around them
- Include service cupboards in routine inspections
New services after handover are a common way fire stopping gets breached. A short check at the end of each job saves a long hunt later.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there.
