Fire stopping for commercial buildings in Kidmore End
No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in. We work on linear gaps at wall heads, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors, and the usual reasons a site gets in touch are service penetrations left open after M&E works and unsealed penetrations discovered above suspended ceilings. Looking for mastic applicators who cover Kidmore End? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Rural conversions around Kidmore End 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 is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Questions we are asked in Kidmore End
Can you work on a hospital site such as Battle Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Does your area include sites such as Oxford Road Business Park, near Kidmore End?
Yes, sites like Oxford Road Business Park are within our area, along with the rest of Kidmore End. To start, just phone 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Does weather matter for sealant work?
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. Internal work is far less affected.
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.
Can you fire stop behind the services contractors?
Yes, where there is a specification for those walls and floors. New services after M&E works often breach existing seals and we close them with the specified product.
How do I request a quote?
The quote form is the simplest route, though you can also call 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.
Are you members of a third-party fire-stopping installer scheme?
No, and we’d rather be clear about that. Third-party schemes aren’t a legal requirement, but many clients and main contractors ask for them, so it’s worth checking what your contract says. If it doesn’t require one, we can install the specified fire-rated sealant to its tested detail.
Our process
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. For work around Kidmore End, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
Before we start on site
- Share your working hours and any access restrictions
- Explain the parking and delivery arrangements
- Make sure the joints can be reached

Leave it or put it right?
Open penetrations multiply: each new service adds to the list. Keeping on top of it after each round of works keeps the job small, rather than turning into a full building survey and reseal. Around Kidmore End, it’s better to renew all the failing joints at once. Send photos of each area and we’ll quote for the lot.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

Aftercare for building managers
Cleaning and maintenance staff play a part too. Share these points with them:
- File the specified details where the next contractor can find them
- Check risers and ceiling voids after each round of works
- Foam or ordinary sealant is never a fire-seal repair
- Arrange inspection before areas are covered up
Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Watch for cracked sealant, new services with no seal and openings that have grown.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open instead of being left for someone else.
Cost factors for service penetrations
The price varies from site to site. It mainly depends on:
- Distance, for remote addresses
- Phasing around occupants
- Removal of failed or old sealant
- Induction, permit and paperwork requirements
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.
Sending details for a quote
It doesn’t need to be a full survey. A few details are enough to get going:
- Approximate linear metres or a joint schedule
- Asbestos survey details if the building is older
- Any specification or named product
- When you need the work done
