Fire rated sealant in Aylesbury
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. We work on flats & HMOs, service penetrations and plasterboard & masonry, and the jobs we see most are sealant items on a fire risk assessment action list and gaps around pipes and cables through fire-resisting walls.
For landlords in a large town like Aylesbury, sealant work comes in two kinds: new sealant in bathrooms and kitchens, and fire-rated joints around service openings. We can quote for a single property or a whole portfolio.
All of our work is guaranteed for twelve months, in Aylesbury and everywhere else we cover.

Do you need fire rated sealant in Aylesbury?
Lots of unsealed gaps appear long after the building was completed. Electricians, plumbers and data installers drill through walls and ceilings and the hole they leave doesn’t always get resealed.
People generally contact us after spotting one of these:
- Open holes round services passing through fire walls
- Gaps flagged on a fire risk assessment
- Fire seals that have cracked with movement
- Seals cut through by electricians, plumbers or data installers
Rented homes near Aylesbury station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.
What your quote should include
- Whether they seal over old material or remove it
- Who turns up on the day
- How the joint is cleaned and prepared
- Whether the sealant suits the joint

Your questions about fire rated sealant in Aylesbury
Do you take on hotel work around Aylesbury?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Do you work for landlords with property near Aylesbury station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
What’s the difference between intumescent and fire-rated sealant?
An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all and which one is used depends on the job.
Can you tell me how many minutes the seal will last?
We do not issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves; we install to those details and record what we did.
How long will you be here?
Typically it takes a few hours for a handful of gaps, and longer for a whole building. Bigger jobs take longer, and we’ll say how long yours will take.
Do you have insurance?
Yes, we’re fully insured for every job we do.
Where are you based?
We work from Crawley. Our applicators cover Aylesbury.
Will we have a record of what was sealed?
Yes. We note each location and the product that went in so it’s there for the next inspection.
What affects the cost of fire rated sealant
Some jobs are bigger than they look, and some smaller. The main factors:
- The type of sealant required
- The number of rooms or windows
- Any mould that needs treating
- The size of the job
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.

- Roughly how big the job is

What happens if it’s left?
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. For businesses in Aylesbury, a room closed because of a leak or mould costs more than the sealant, so it pays to replace failing joints before they get that far.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What fire rated sealant looks like in Aylesbury
Aylesbury has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Community buildings like Church of St Mary are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. If you look after a building such as Buckinghamshire UTC, fire-stopping around service openings should be restored whenever new services go in.

- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- We record the locations and products used for your records.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can
