Landlords, managing agents and facilities teams use us for the sealant items on a fire risk assessment on buildings across Lenham. Send us the list or the survey and we will quote for the fire-rated sealant work on it. We work on door frames, plasterboard & masonry and flats & HMOs, and people most often call us about gaps where walls meet ceilings or slabs and joints picked up in a fire-stopping survey.
In a smaller place like Lenham, commercial jobs tend to be smaller buildings: a pub, a surgery, a school, a shop or a few business units. Each needs the same care with its sealant as any larger building.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Workplaces and buildings in Lenham
Lenham has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. 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, 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.
Managing a site like Lenham Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices. Community buildings like St Mary's Church are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

What we cannot put right
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Construction that does not provide fire resistance on its own
- Fire risk assessments, which need a qualified assessor
- Big openings where sealant alone isn’t the tested solution
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.
What we seal
- Plasterboard & masonry
- Pipe & cable gaps
- Linear gaps
- Service penetrations
- Flats & HMOs
- Door frames
Why deal with it now?
If an assessor has flagged gaps, it makes sense to close them before the next review. Getting them done and written up gives you evidence that the item was dealt with. Around Lenham, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.

What affects the quote in Lenham
The quote reflects the job in front of us. We look at:
- How much old sealant there is and how hard it is to remove
- How many rooms, windows or areas are involved
- Whether the work is at height
- The product the joint needs
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- Any previous sealing or DIY work
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it’s a home or a business
For fire rated sealant in Lenham, ring 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.
How it works
We keep the work tidy and contained to the joints we are treating, so you can get on with your day. Expect the work to take from a few hours to a few days, depending on the number of gaps and the access, and we tell you how long to leave it before we go. For a job in Lenham, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since 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.
- Dust and loose debris are cleaned from each gap.
- 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.
Getting ready for the visit
- Clear items away from the joints we are working on
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints

In most cases you can choose. We will tell you which colours the right product comes in and agree one before work begins.
Do you work in flats, HMOs and commercial buildings?
Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Let us know the building’s hours and we will plan the work to suit.

Common problems we fix in Lenham
Door frames are a common weak spot. The gap between the frame and the wall is hidden behind the architrave, so it’s easy to leave unsealed when doors are changed.
Any of these means the joints need attention:
- Open gaps behind door architraves
- Gaps filled with a product that isn’t fire-rated
- Fire seals that have cracked with movement
- Unsealed gaps where pipes and cables go through a wall
Rented homes near Lenham station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
What your quote should include
- What the cure time is
- Who does the work, and how experienced they are
- Is VAT in the price?
- What happens if they find a problem under the old sealant
How the job changes by surface
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Crumbling edges are cleaned back before the sealant goes in.
Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We seal them along their full length leaving no stretch unsealed.
