Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Fire rated sealant in Marlow, done properly
Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. Common call-outs are for open joints along the top of partitions and gaps filled with a product that isn’t fire-rated, on plasterboard & masonry, flats & HMOs and linear gaps.
Shared washrooms take far more use than a home bathroom, and their sealant shows it, while fire-rated sealant has to be made good whenever new pipes or cables go through. In Marlow, timings are planned around the building.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

For landlords and businesses

We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Keep the record of products and locations with your fire safety documents
- Make resealing part of every contractor’s brief
- Get damaged fire seals looked at promptly
- Ask which product was used before you paint
File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.
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.
What happens on the day
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for a handful of gaps, and longer for a whole building. Parking in a town like Marlow is usually straightforward, but tell us if there’s a driveway or any restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- 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
- For business premises, tell us about site rules or sign-in
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky

Advice
Common problems we fix in Marlow
Door frames are a common weak spot. The architrave hides the gap between frame and wall, so it’s easy to leave unsealed when doors are changed.
Most people get in touch after spotting one of these:
- Ordinary sealant used where a fire-rated product was needed
- Sealant items on a fire risk assessment action list
- Old fire sealant that has split or come away
- Fire stopping disturbed by later work
For site and facilities teams at buildings such as Holy Trinity Church of England (Aided) School, gaps opened by contractors for new cabling are a common finding in schools and offices.
What your quote should include
- Whether VAT is included
- Whether they’re fully insured
- Whether you can choose the colour
- Is the old sealant removed completely?
What fire rated sealant looks like in Marlow
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. There are hotels and other places to stay in and around Marlow. Hotel work can be planned room by room, with out-of-hours working where needed.
If you let a flat or house near Marlow station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Community buildings like Congregational Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

How do I get a quote for fire rated sealant in Marlow?

Why act early in Marlow
An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the sealing itself is often a contained piece of work. Gaps in sealant and mould in the bead never get better on their own, and in a busy household in Marlow they spread with every shower and every downpour. Replacing the sealant now is the simplest fix.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
