Hareplain Fire Rated Sealant
Professional fire rated sealant in and around Hareplain, with every bit of old sealant taken out first and a one-year guarantee.
- Damaged fire sealant left by other trades
- Old fire sealant that has split or come away
- Gaps left after a refit or conversion
How to look after the new joints
To keep the joints looking good and working properly:
- Include fire stopping when you schedule refits
- Make resealing part of every contractor’s brief
- Check risers, ceiling voids and cupboards during building checks
- Keep the record of products and locations with your fire safety documents
Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and get them seen to.
Open gaps do not only matter in a fire: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
Fire rated sealant in Hareplain
Fire stopping only performs as intended if it’s done to the detail: the right depth, the right backing and the right product for the substrate. That detail is what we take care over, one gap at a time. We work on pipe & cable gaps, flats & HMOs and plasterboard & masonry, and the jobs we see most are gaps around pipes and cables through fire-resisting walls and damaged fire sealant left by other trades.
Work in a small place like Hareplain is planned ahead, journey included, so it can be fitted around guests, clients or events where possible.
Every job comes with our one-year guarantee.

Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What fire rated sealant looks like in Hareplain
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, 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.
Around Hareplain, as everywhere, fire rated sealant is only as good as the preparation behind it.

Why it’s worth doing now in Hareplain
Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, and we work to the product details every time. Around Hareplain, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

- Any working-time requirements on site
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Call for a quick quote and we’ll go through it with you.
What to tell us for a quote
Before you ask for a quote, have a think about:
- The problem you’ve noticed
- Any previous sealing or DIY work
- Where the job is, and your postcode
- The rough size of the job
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
Work for landlords, hotels and businesses
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
The process
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes from a few hours to a few days, depending on the number of gaps and the access. In a small place like Hareplain, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Access to each area is agreed so the work can run in order.
- 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.
Before we arrive
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can
- Tell us about access, such as stairs, a lift or high-level joints
