How we handle fire rated sealant in Chertsey
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. A new cable run or a replaced pipe can leave an open hole behind. Those are the gaps we close, using a tested fire-rated product. We work on linear gaps, service penetrations and door frames, and the jobs we see most are sealant items on a fire risk assessment action list and old fire sealant that has split or come away.
In a smaller place like Chertsey, 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.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

When something else is needed
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Fire doors that need new seals, closers or hardware
- A wall that isn’t a fire-resisting element to begin with
- Fire risk assessments, which need a qualified assessor
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly before you book.
Where we work in Chertsey
- Flats & HMOs
- Service penetrations
- Plasterboard & masonry
- Door frames
- Pipe & cable gaps
- Linear gaps
Different surfaces, different methods
Flats and HMOs
Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified.
Service penetrations
Service penetrations are where new gaps often appear. We clean out what’s there and reseal to the right depth with backing where the detail needs it.
Looking after it afterwards
To keep the joints looking good and working properly:
- Allow for resealing whenever new services are run
- Keep pictures of seals that will be hidden
- Include hidden areas like risers in routine checks
- Check whether a sealant can be painted before decorating over it
Avoid covering a sealed gap with anything that is not part of the tested detail. If it needs repair, use the same type of product. We can tell you which product we used.
Open gaps do not only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
What happens if it’s left?
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. In an older home around Chertsey, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or drop us an email and we will talk you through it.

How it works
On the day, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before work begins. Most jobs take a few hours for a handful of gaps, and longer for a whole building. In a smaller place like Chertsey, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- We record the locations and products used for your records.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises
- Move anything stored near the joints

When to call us in Chertsey
Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
The problems people usually mention when they call are:
- Seals cut through by electricians, plumbers or data installers
- Holes left by a change of layout
- Standard silicone or caulk in a fire-stopping gap
- Cracked or shrunken fire-rated sealant
For site and facilities teams at buildings such as St Anne's Catholic Primary School, fire-stopping around service openings should be restored whenever new services go in.
What to look for in a quote
- How the colour is chosen
- How the joint is cleaned and prepared
- The length of the guarantee
- When the joint can take water or movement
What else we do in Chertsey
Fire rated sealant around Chertsey
Chertsey has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.
If you look after a church, hall or community building such as Church of St Peter, gaps around pipes and cables are worth checking after any building work there. If you let a flat or house near Chertsey station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

FAQs for Chertsey
I let a flat near Chertsey station. Can you help?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you work in hotels near Chertsey?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Do you do fire sealant around door frames?
Yes. We often seal open gaps hidden behind the architrave. Doors, seals and closers need a door specialist.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first.
Can you tell me how many minutes the seal will last?
That is not something we state or certify. The requirement comes from your assessor, designer or building control, and we apply a product tested for it with a record of each location.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
