How it works
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes anything from a few hours to several days, depending on how many gaps there are. In a smaller place like St Stephens, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
How to prepare
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can
- Let us know if you’ve seen damp or leaks

Fire rated sealant in St Stephens
We often work from an action list drawn up by a fire risk assessor. If you share the list, we can quote for the gaps that need fire-rated sealant. Common call-outs are for joints picked up in a fire-stopping survey and open holes round services passing through fire walls, across door frames, plasterboard & masonry and service penetrations.
Commercial work around a smaller place like St Stephens generally means a pub, a shop, a school or small business units rather than office blocks. The work is the same as in a big building, just on a smaller scale.
All of our work is guaranteed for twelve months.

Aftercare tips
A little care helps the new joints last. We recommend:
- Allow for resealing whenever new services are run
- Get damaged fire seals looked at promptly
- Check risers, ceiling voids and cupboards during building checks
- Keep pictures of seals that will be hidden
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and get them seen to.
An open gap is not only a fire issue: noise, draughts and even pests can come through too. Sealing them early helps on every front.
When it isn’t the sealant
Before you book, it’s worth knowing the limits too:
- A wall that is not a fire-resisting element to begin with
- Doors that are not fire doors in the first place
- Certifying a building or signing off its fire safety
If in doubt, ring 0345 464 0079 or email us and we will say what we think.

Why deal with it now?
Doing it once, properly, beats doing it twice. Work that doesn’t follow the tested detail may have to come out again when the building is next checked. Homes in smaller places like St Stephens can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Leaving a failed joint generally makes the job bigger, not smaller, 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.

Questions from St Stephens
Do you cover smaller places like St Stephens?
Yes. St Stephens is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you help a landlord with a rental near St Albans Abbey station?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Can you match the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
Is intumescent sealant the same as fire-rated sealant?
An intumescent sealant expands when it gets hot. It’s one type of fire-rated sealant; the right one depends on the gap and what passes through it.
Will you assess my building’s fire safety?
No. We work from the specification you give us.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Will we have a record of what was sealed?
Yes. When the job is done, we give you the locations and products. Tell us if your assessor needs it in a particular format.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Commercial buildings in St Stephens
There are hotels and other places to stay in and around St Stephens. 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 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 St. Stephen's Church, older buildings that have had new heating or wiring often have service gaps worth checking. Schools such as Marlborough Science Academy are buildings too, and fire-stopping around service openings should be restored whenever new services go in. Rented homes near St Albans Abbey station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

How the job changes by surface
Door frames
The gap between a door frame and the wall around it needs sealing as well as the door itself. We seal that gap with a fire-rated sealant suited to the frame and wall.
Masonry and concrete
Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it.
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
