About our fire rated sealant in Chelmsford
Deciding which gaps need fire stopping is not our role; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. If you’re dealing with old fire sealant that has split or come away and gaps filled with a product that isn’t fire-rated, we can put it right.
A place the size of Chelmsford has offices, shops, hotels and schools, all with washrooms, kitchens and service openings that need the right sealant. Our work covers washroom and kitchen sealant as well as fire-rated sealant, fitted to the product’s tested details.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.
What happens on the day
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 any work starts. The work usually takes a few hours for a handful of gaps, and longer for a whole building. In central Chelmsford, parking can be tight, so tell us about driveways, permits or nearby car parks. Let us know about stairs, lifts or shared entrances too.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- We remove any old or unsuitable filler and clean the gap.
- 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.
- Finally, we list where we worked and what we used, for your records.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed
- Clear the area around the work

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Surface by surface
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. We use a product tested in that kind of wall.
Door frames
Behind most architraves is a gap between frame and wall. We seal any open gap to the product’s tested details.
Why deal with it now?
Doing it once, properly, beats doing it twice. Work that does not follow the tested detail may have to come out again when the building is next checked. In a busy place like Chelmsford, a failed joint in a flat or office can send water into the space below, where it’s often found late and is bigger to put right.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
What you get with us
- 12-month guarantee on every job
- Over 20 years’ experience
- Fully insured
- An ARBOMaster approved applicator

Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
We work for landlords and agents as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Commercial buildings in Chelmsford
Chelmsford has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. 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, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
For landlords with property near Chelmsford station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a church, hall or community building such as Church of the Holy Trinity, service openings in its walls need the right fire-rated sealant, as in any building.

What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Allow for resealing whenever new services are run
- File the fire-stopping record where your assessor can find it
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Photograph sealed gaps before they’re covered up
File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.
A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record so you can show it was dealt with.
What we’re called out for in Chelmsford
If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it is not installed as tested. We see plenty of fire stopping that was hurried particularly when it was the last job before handover.
The most common problems we see are:
- Open gaps behind door architraves
- Gaps where walls meet ceilings or slabs
- Damaged fire sealant left by other trades
- Old fire sealant that has split or come away
Schools such as Trinity Road Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.
