Fire stopping in Mark Hall North
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 part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail rather than guesswork. We work on service gaps in risers, joints between fire-resisting walls and floors and small duct penetrations where the tested detail allows, and the usual reasons a site gets in touch are openings left by services added after handover and head-of-wall gaps with no fire seal. A single leaking joint is often how a building in Mark Hall North first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Fire-rated sealing in a place like Mark Hall North is typically a single building at a time. With the specification and photos of the gaps, we can give a fixed quote and bring the right products.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Buildings from the planned-town era have been rewired and replumbed over the years, and each change may have left gaps in fire-resisting walls.

Cost factors for service penetrations
We price every job individually. The things that drive the figure:
- The site’s rules and procedures
- Backing rod, priming and other preparation
- The product specified
- Removal of failed or old sealant
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
Before you send an enquiry
There’s no need for a formal survey. These details are enough to start:
- What the building is and how it’s used
- The site address and postcode
- The asbestos register, for older buildings
- Specification clauses that apply

Mark Hall North: questions and answers
Can work at a site such as Harlow College fit around teaching?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is a smaller place like Mark Hall North outside your area?
No. Places such as Mark Hall North are covered as much as the big towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
What about RAMS and site documents?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
How long will the new sealant 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.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Do you work in Scotland as well as England?
Our area runs from Greater London and the South East to every part of Scotland. Scotland’s non-domestic Technical Handbook, clause 2.1.14, expects service penetrations to be fire stopped to at least the wall or floor’s fire resistance, using products tested for their end use.
Surface by surface
Plastic pipes
Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail, but many need a collar or wrap. We check the pipe material and diameter against the detail before we start.
Small ducts
Some fire-rated sealant details cover small ducts. Bigger ducts and fire-resisting ductwork are normally handled with other products.
Should maintenance staff do it?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact.

A fixed quote follows.

Related advice
Looking after the joints
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Include service cupboards in routine inspections
- Settle who seals which penetrations at the start of a project
- Record which product was used where
- Don’t let anyone top up a fire seal with the wrong product
After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail.
Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.

Do you need fire stopping in Mark Hall North?
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 and the opening isn’t always resealed.
Site and facilities staff are often the first to spot these:
- Openings left by services added after handover
- Fire stopping installed outside its tested range
- Old intumescent sealant that has split away
- Unsealed penetrations discovered above suspended ceilings
Halls and meeting rooms at places like St Andrew's Methodist Church sometimes gain new services, and any compartment wall crossed needs the specified seal.
