How we handle fire rated sealant in Hoo St Werburgh
A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. Measuring the gap and checking what it’s made of comes first, then the sealant goes in to the depth the product’s details set. We work on flats & HMOs, linear gaps and plasterboard & masonry, and common reasons people get in touch are gaps left after a refit or conversion and unsealed gaps where pipes and cables go through a wall.
Community buildings, schools and small businesses around places like Hoo St Werburgh have washrooms and kitchens that see a lot of use. Sealant and fire-rated joints there matter as much as in any larger building.

How the visit works
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on how many gaps there are. A visit to Hoo St Werburgh is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Old or unsuitable sealant is cut out and the gap cleaned.
- Where the tested detail needs backing or fill, we fit it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- We record the locations and products used for your records.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed
- Tell us if parking is tricky

Commercial buildings in Hoo St Werburgh
If you run a hotel, guest house or holiday let in a coastal place like Hoo St Werburgh, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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.
If you look after a church, hall or community building such as Church of St Werburgh, service openings in its walls need the right fire-rated sealant, as in any building. If you look after a building such as Hoo St Werburgh Primary School and Marlborough Centre, service openings in fire-resisting walls need checking after any refurbishment.

Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Keep photos of seals that will be hidden
- Plan fire stopping into any work that goes through walls or floors
- Keep the record of products and locations with your fire safety documents
- Ask every contractor to reseal any fire stopping they disturb
Don’t add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. We can tell you which product we used.
If a fire risk assessment has flagged a gap, do not leave it for the next one. Have it sealed, then keep the record so the item can be closed.
What affects the quote in Hoo St Werburgh
The quote reflects the job in front of us. We look at:

- The old material and how stubborn it is
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What to tell us for a quote
To make quoting easier, please include:
- What the problem is, such as mould, gaps, leaks or cracking
- Roughly how big the job is
- If it’s domestic, commercial or a hotel
- Photos by email, if that is easy
Call for a quick quote, or email us if that is easier. Describe what needs sealing and we’ll talk you through the work and send you a clear quote.
Why act early in Hoo St Werburgh
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. A proper seal lets the wall do its job again, and the sealing itself is often a contained piece of work. Homes in smaller places like Hoo St Werburgh can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.

Can you do fire rated sealant in Hoo St Werburgh?

Do you seal gaps around fire door frames?
Yes, if the gap is within the product’s tested range. Our work is the gap around the frame, and we’ll mention anything we notice about the door.
What should I tell you?
Let us know what needs doing and where, with pictures by email if possible. We will ask anything else we need to know.
Can you tell me which gaps need fire stopping?
No. Your fire risk assessor, designer or building control decides that. We apply fire-rated sealant to the requirements they set.
What fire rating will the seal have?
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, and we install to them.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Is there any odour?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Surface by surface
Plasterboard walls
We check that the board around the gap is sound. Crumbling edges are cleaned back before the sealant goes in.
Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We work along the whole run so there are no open sections left.
