How the visit works
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes anything from a few hours to several days, depending on how many gaps there are, including the tidy-up. In a smaller place like Pennington, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- Access to each area is agreed so the work can run in order.
- 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.
How to prepare
- Keep pets and children clear of the area while we work
- Tell us about any water getting in
- Let us know about stairs, lifts or work at height

What happens if it’s left?
Paying for fire stopping that has to be redone is a false economy. Work that doesn’t follow the tested detail may have to come out again once someone inspects it. Around Pennington, 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.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

FAQs for Pennington
Is Pennington within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Lymington Town station. Can you help?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Will you assess my building’s fire safety?
No. Your fire risk assessor, designer or building control decides that. We apply fire-rated sealant to the requirements they set.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you tell me how many minutes the seal will last?
Ratings and certification sit with the product’s test evidence and whoever specified the work. Our part is installing the specified product to its tested details and list the locations and products for you.
How long does fire rated sealant take?
A typical job takes anything from a few hours to several days, depending on how many gaps there are, including the preparation. Your quote will say how long we expect yours to take.
Do you provide details of the products used?
Yes. When the job is done, we give you the locations and products. Tell us if your assessor needs it in a particular format.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
When it isn’t the sealant
In fairness, some problems need a different trade:
- Doors that aren’t fire doors in the first place
- Construction that doesn’t provide fire resistance on its own
- Fire risk assessments, which need a qualified assessor
If you are not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.
What we seal
- Door frames
- Flats & HMOs
- Plasterboard & masonry

How the job changes by surface
Masonry and concrete
Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it.
Door frames
A door can only do its job if the gap behind its frame is sealed too. We fill it with a fire-rated product suited to the materials either side.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
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.
