Hythe questions
Can you help a landlord with a rental near Sandling station?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Is there a guarantee on fire rated sealant in Hythe?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Can you fill the gap behind a fire door frame?
Yes. We seal the gap between the frame and the wall with a suitable fire-rated product, to the product’s details. The door leaf and its hardware need a door specialist.
How much does fire rated sealant cost in Hythe?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or drop us an email with a short description of the job.
What does intumescent mean?
An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant.
Fire rated sealant in Hythe
We can work through a building room by room or floor by floor. It gives you a list to keep with the building’s fire safety documents. We are often asked to deal with linear gaps at the head of walls and fire stopping disturbed by later work, on service penetrations, linear gaps and door frames.

How the visit works
At the end, we look at the finished work together. The work normally takes anything from a few hours to several days, depending on how many gaps there are, depending on the amount of work. A visit in Hythe needs access to the work and a place to park close by. If the job is outside, mention gates, side access and anything above ground floor.
- We start with the survey or action list, checking the size and surfaces of every gap.
- We remove any old or unsuitable filler and clean the gap.
- Where the tested detail needs backing or fill, we fit it.
- 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 any water getting in
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children

What else we do in Hythe
Fire rated sealant in Hythe: local notes
For seaside hotels, guest houses and holiday lets around Hythe, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. 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.
For landlords with property near Sandling station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. For buildings such as Church of St Michael and All Angels, gaps around pipes and cables are worth checking after any building work there.
Hythe is about 4 miles west of Folkestone, in Kent. We provide fire rated sealant to homes and businesses in Hythe and the surrounding area. Our Kent coverage runs to 922 places, and Hythe is one of them. Our Chelmsford page covers work nearby (53 miles or so).

How we quote for fire rated sealant
We quote each job individually. This is what makes a difference:
- How much there is to do
- Whether the work is at height
- The type of sealant required
- When we can work, for business premises
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What we need to know
What to tell us when you ask for a quote:
- Where the job is, and your postcode
- What’s wrong with the joints now
- How many joints, rooms or windows are involved
- The type of property
It all starts with a short chat. Describe the problem, the location and the size of the job. Whenever you’re ready, phone 0345 464 0079 or email us.
What happens if it’s left?
For some gaps, sealant is not the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. We will say so if a gap needs something other than sealant. Around Hythe, failed sealant lets water into hidden places, like the floor under a bath, the back of a panel or the inside of a wall. Whatever the joint, failed sealant only gets worse.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

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 flag it.
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing so the sealant bonds.
Do you need fire rated sealant in Hythe?
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
- Open joints along the top of partitions
- Damaged fire sealant left by other trades
- Sealant items on a fire risk assessment action list
If you look after a building such as Hythe Bay CofE Primary School, fire-stopping around service openings should be restored whenever new services go in.
