- Open gaps behind door architraves
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Report cracked or damaged seals as soon as you notice them
- Check risers, ceiling voids and cupboards during building checks
- Allow for resealing whenever new services are run
- Photograph sealed gaps before they’re covered up
Do not drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.
Fire rated sealant in Carterton
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate. We work on service penetrations, linear gaps and flats & HMOs, and the jobs we see most are gaps left after a refit or conversion and door frames with gaps between frame and wall.
For anyone managing a school, care home, pub or office in Carterton, the sealant in its washrooms and kitchens, and the fire-rated joints around its pipework, all need looking after. Out-of-hours working is possible to arrange.
Your job is guaranteed for a year, as with all our work.

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Signs you need fire rated sealant in Carterton
In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It looks sealed, but it is not fire-rated.
It’s worth asking for a quote if you see:
- Gaps around pipes and cables through fire-resisting walls
- Damaged fire sealant left by other trades
- Joints picked up in a fire-stopping survey
- Unsealed gaps around fire door frames
Managing a site like Carterton Primary School? Then service openings in fire-resisting walls need checking after any refurbishment.

FAQs for Carterton
How do I get a quote for fire rated sealant in Carterton?
The easiest way is to call 0345 464 0079 or send us an email with a few details of the job. We will give you a clear price, with a fixed price before any work starts.
What guarantee comes with fire rated sealant in Carterton?
All our work, in Carterton and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
How long will you be here?
Most jobs take from a few hours to a few days, depending on the number of gaps and the access, including the preparation. Your quote will say how long we expect yours to take.
Do you work in flats, HMOs and commercial buildings?
Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Let us know the building’s hours and we’ll plan the work to suit.
Will you assess my building’s fire safety?
No, we do not assess buildings. Once you have a specification or action list from your assessor or designer, we can quote for the fire-rated sealant items.
Can ordinary silicone be used in a fire-stopping gap?
No. A gap that needs fire stopping needs a tested fire-rated product fitted to the maker’s details.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
Leave it or put it right?
Sealant is not the fix for every opening. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. We’ll say so if a gap needs something other than sealant. In a family home in Carterton, a failed seal around a bath or a frame lets water into places you cannot see, 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.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

What the job involves on each surface
Service penetrations
Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. We seal it with a product tested for that service and gap size.
Masonry and concrete
Core-drilled and broken-out holes in concrete are often irregular. We check the gap size around the service to make sure it suits the product.
How it works
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on how many gaps there are. A visit in Carterton needs access to the work and a place to park close by. For outside work, let us know about side access, gates and any upper-floor joints.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- We put in whatever backing or fill the product detail specifies.
- 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
- Try not to wet indoor joints just before the visit
- Mention any sign-in or site rules at work premises
- Mention any tricky access

What fire rated sealant looks like in Carterton
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.
Community buildings like St John the Evangelist are part of the picture too: gaps around pipes and cables are worth checking after any building work there.
