What affects the cost of fire rated sealant
For a quick quote, just ask. The main things that affect it are:
- How much there is to do
- Mould in or behind the old joints
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.

Fire rated sealant in Little Marlow, done properly
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. If you have door frames with gaps between frame and wall and damaged fire sealant left by other trades, we can put it right.
In a village or hamlet like Little Marlow, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
We stand behind the work with a one-year guarantee, so you are covered after we have gone.

Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

What else we do in Little Marlow
Why act early in Little Marlow
Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, so we follow the maker’s details on every gap. Around Little Marlow, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Signs you need fire rated sealant in Little Marlow
Over time, buildings change layout and use. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
These are the problems we are asked about most:
- Holes left by a change of layout
- Gaps flagged on a fire risk assessment
- Open holes round services passing through fire walls
- Gaps where walls meet ceilings or slabs
For site and facilities teams at buildings such as Little Marlow CofE School, service openings in fire-resisting walls need checking after any refurbishment.
Before booking anyone

- Whether they’re fully insured

Little Marlow questions
I let a flat near Bourne End station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Will you come out to Little Marlow?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you tell me how many minutes the seal will last?
We do not give ratings or certificates for our work. Your specification sets the requirement, and we fit a product whose tested details meet it with a record of each location.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Where are you based?
We are based in Crawley, and we work across South East England, London and Scotland.
Do you carry out fire risk assessments?
No. That’s for a fire risk assessor, designer or building control. Our job is applying the sealant to their specification.
Do you seal gaps around fire door frames?
Yes, if the gap is within the product’s tested range. We seal the frame-to-wall gap, not the door itself and we’ll tell you if we spot problems with the door.
How it works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself normally takes anything from a few hours to several days, depending on how many gaps there are, depending on the amount of work. Somewhere like Little Marlow needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the faces cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your files.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts

Looking after it afterwards
So the new joints stay in good condition:
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Keep photos of seals that will be hidden
- Flag any open gap you spot round a pipe or cable
- File the fire-stopping record where your assessor can find it
Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.
It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole and the list grows.
