Fire stopping for The Hythe sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
How the job changes by surface
Drylining partitions
Service holes through plasterboard are frequently oversized or ragged. If the gap exceeds the tested range, sealant alone won’t do and we will tell you what the detail says instead.
Small ducts
Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Larger or fire-rated ductwork normally needs a different solution set by the designer, and we’ll say if that applies.
About our fire stopping in The Hythe
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal. Most enquiries involve unsealed joints where partitions meet the slab and unsealed openings around new pipes and cables, across small duct penetrations where the tested detail allows, cable penetrations and joints between fire-resisting walls and floors.

Around smaller places like The Hythe, many commercial buildings are conversions or extensions of older ones, so it’s worth confirming the wall or floor type before choosing the seal. The right product depends on the wall or floor and the services passing through, and we will tell you if the detail calls for something other than sealant.
We stand by our work: 12 months, guaranteed. That covers our preparation and application.

Should maintenance staff do it?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
On site: what to expect
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work normally takes anything from one day to a planned run of visits, depending on the number of seals and the access. What matters most for a job in The Hythe is a clear list of what needs doing, so send photos of each area. A fixed quote follows.
- The specification and schedule come first, so we know which details apply.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Before we start on site
- Let building users know which areas are affected
- Confirm the product named in the specification
- For older buildings, check the asbestos register before work

Cost factors for service penetrations
To price the job, we consider:
- How much there is to seal
- Removal of failed or old sealant
- Location, for remote and island sites
- Working within restricted access windows
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
Sending details for a quote
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- The asbestos register, for older buildings
- The product your specification calls for
- Anything awkward about access or site hours
- Whether the building will be occupied during the work
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
Maintenance after handover
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Put resealing into every M&E and fit-out package
- Don’t let anyone top up a fire seal with the wrong product
- Settle who seals which penetrations at the start of a project
- Leave fire sealant to cure fully before covering it
Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original unless the designer specifies otherwise.
On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned.
Compartments and services around The Hythe
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. The Hythe is about 51 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product.
In a retail centre such as Hunwicke Shopping Centre, which lies north-east of The Hythe, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail. Residences at universities like University of Essex (0.9 miles south-east of The Hythe) have compartment walls that must be resealed whenever services change. Wherever services are added at a hospital such as Oaks Hospital (to the north-west of The Hythe) the compartment line has to be made good with the specified product.
The Hythe is about 1 mile south-east of Colchester, in Essex. Any commercial site in The Hythe is covered, whether it’s a single job or part of a planned programme. We work across 644 places in Essex, large and small. We also cover London, some 51 miles away.
Anyone looking for fire stopping in CO1, CO4 and CO2 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. If your site is on Port Lane, Beche Road and Haven Road or close by, we can quote for service penetrations. Nearby places we also cover include Greenstead (1 mile north-east), Old Heath (1 mile south), Berechurch (2 miles south-west), Wivenhoe Cross (2 miles south-east) and Crockleford Heath (2 miles north-east) for service penetrations. Bigger towns within reach include Clacton-on-Sea (11 miles south-east), Maldon (15 miles south-west), Witham (14 miles south-west), Harwich (15 miles east), Halstead (13 miles west) and Heybridge (14 miles south-west).

When something else is needed
Honesty saves time and money. Fresh joints won’t solve:
- Fire risk assessments, a job for a competent assessor
- Plastic pipes whose detail calls for a collar or wrap
- Gaps in walls that were never built as compartment walls
If you’re not sure, just give us a call on 01277 525 020 or email us and we’ll give you a straight answer.

Your questions answered
Is The Hythe too small for you to travel to?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Could you schedule work at a campus like University of Essex for the vacation?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we will confirm them alongside the quote.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Do you certify or sign off fire stopping?
No. Sign-off belongs to the designer or building control, not the installer. We’ll confirm the products and details used, and you can tell us what other records you need at quote stage.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
