Fire rated sealant for homes and businesses in Chaulden
We can work through a building room by room or floor by floor, with each location and product recorded. That record is useful for your files and for whoever looks at the building next. If you’re dealing with holes left by a change of layout and door frames with gaps between frame and wall, we can put it right.
Commercial work around a smaller place like Chaulden 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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Landlord and commercial work in Chaulden
For anyone letting property in or around Chaulden, several properties can go on one quote. Send us the addresses and the work at each, and pictures by email help.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
How we quote for fire rated sealant
Your quote is based on your job. We look at:
- How many rooms, windows or areas are involved
- The old material and how stubborn it is
- Mould in or behind the old joints
- How much there is to do
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and give you a clear price before any work starts.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Any previous sealing or DIY work
- Any access issues, like height or stairs
- How many joints, rooms or windows are involved
- Whether it’s a home or a business
Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand, and we will take it from there.
How it works
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on how many gaps there are. Parking around Chaulden is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- 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.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work

Advice
How to look after the new joints
Looking after new joints is easy:
- Include hidden areas like risers in routine checks
- Keep pictures of seals that will be hidden
- Include fire stopping when you schedule refits
- Don’t fill fire-stopping gaps with ordinary foam or silicone
Tell other trades that the gaps have been sealed, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.
Surface by surface
Masonry and concrete
Masonry is dusty and porous, so preparation matters. The gap is cleaned and backed where required before the sealant goes in.
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. The sealant has to be one tested in plasterboard for the gap we are sealing.

What we are called out for in Chaulden
Gaps also open up as buildings move: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.
The most common problems we see are:
- Unsealed gaps where pipes and cables go through a wall
- Damaged fire sealant left by other trades
- Gaps flagged on a fire risk assessment
- Holes left by a change of layout
Managing a site like Chaulden Junior School? Then fire-stopping around service openings should be restored whenever new services go in.
What your quote should include
- How long to leave it before use
- Is VAT in the price?
- Whether they’re fully insured
- Whether the sealant suits the joint
Commercial buildings in Chaulden
Hemel Hempstead, which Chaulden is part of, is one of England’s post-war new towns. Hemel Hempstead was planned with its own industrial and business areas, so there are offices, units and workplaces not far from home. Their washrooms, kitchens and fire-rated joints need the same upkeep as anywhere. 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’re given, installing the product to its tested details.
If you look after a church, hall or community building such as St Stephen, gaps around pipes and cables are worth checking after any building work there. If you let a flat or house near Hemel Hempstead station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

FAQs for Chaulden
Can you help a landlord with a rental near Hemel Hempstead station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.

Yes. We work across London and the South East, and Chaulden is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll send you a clear quote.
Will you assess my building’s fire safety?
No. That’s for a fire risk assessor, designer or building control. We apply fire-rated sealant to the requirements they set.
Can ordinary silicone be used in a fire-stopping gap?
No. A gap that needs fire stopping needs a tested fire-rated product, installed to its details.
Can you tell me how many minutes the seal will last?
Ratings and certificates are not something we issue. The performance comes from the product’s tested details and the specification from your assessor or designer, and we install to them.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Can you match the sealant colour?
In most cases you can choose. We’ll tell you which colours the right product comes in and agree one before work begins.
Do you seal gaps around fire door frames?
Yes. We seal the gap between the frame and the wall with a suitable fire-rated product, to the product’s details. The door leaf and its hardware need a door specialist.
