DIY sealant or a professional job?
If you are 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 fails, we can still redo it.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
How we handle fire rated sealant in Haddenham
Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it, so we work to the manufacturer’s details. If you are dealing with new service routes left unsealed after building work and gaps around pipes and cables through fire-resisting walls, we can help, on flats & HMOs, service penetrations and pipe & cable gaps alike.
Around a place like Haddenham, halls, schools and small businesses all have washrooms and kitchens used by many people. Sealant and fire-rated joints there matter as much as in any larger building.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or drop us an email.

Your questions about fire rated sealant in Haddenham
Can you do fire rated sealant in Haddenham?
Yes. We work across London and the South East, and Haddenham is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Do you cover smaller places like Haddenham?
Yes, Haddenham is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Will we have a record of what was sealed?
Yes. You get a list of where we worked and what we used.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
How much does fire rated sealant cost in Haddenham?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Haddenham.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
Do you do fire sealant around door frames?
Yes. We seal the gap between the frame and the wall with a suitable fire-rated product following the tested details. The door leaf and its hardware need a door specialist.
What affects the cost of fire rated sealant
The quote reflects the job in front of us. We take into account:
- Working hours on commercial sites
- Any mould that needs treating
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.
What we need to know
What to tell us when you ask for a quote:
- The address or postcode of the job
- What’s wrong with the joints now
- How we’d reach the joints
- Whether it’s a home or a business

Why it’s worth doing now in Haddenham
Leaving a gap until a refurbishment comes round can mean years with it open. Sealing the gap now is a contained job on its own. Around Haddenham, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and give you a clear price before any work starts.

Different surfaces, different methods
Plasterboard walls
Holes in plasterboard are often cut roughly for services. Gaps that are too big for sealant alone need a different detail, and we will tell you.
Masonry and concrete
Preparation counts on brick, block and concrete. The gap is cleaned and backed where required before the sealant goes in.
What fire rated sealant looks like in Haddenham
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 work to the specification you are given, installing the product to its tested details.
If you let a flat or house near Haddenham & Thame Parkway station, any gap left by new services in shared walls should be closed with a fire-rated product. For buildings such as Parish Church of St Mary, gaps around pipes and cables are worth checking after any building work there. Schools such as Haddenham Community Infant School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.

What happens on the day
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. A visit to Haddenham is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We plan the order of work and access, floor by floor or flat by flat.
- We take out any damaged or unsuitable sealant.
- Gaps are cleaned of dust and loose material.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children

Advice
What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- Walls or floors that weren’t built to resist fire
- Openings too large for sealant, which need batts, boards or another system
- Fire doors that need new seals, closers or hardware
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before booking.
