Common questions in Newnham
Can you help a landlord with a rental near Baldock station?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Do you cover Newnham for fire rated sealant?
Yes. We work across London and the South East, and Newnham is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll send you a clear quote.
Can you give us a record of the work?
Yes. You get a list of where we worked and what we used to keep with your fire safety documents.
How do I get a quote for fire rated sealant in Newnham?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Do you have insurance?
Yes. We’re fully insured, and we can confirm the details when we quote.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Can ordinary silicone be used in a fire-stopping gap?
No. It might close the gap, but it isn’t a fire-rated seal. Use a product tested for that gap and service, or ask us to do it.
When something else is needed
It helps to know what we cannot do too:
- Big openings where sealant alone isn’t the tested solution
- Deciding what fire stopping a building needs
- Fire doors that need new seals, closers or hardware
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

Fire rated sealant in Newnham: local notes
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 work to the specification you are given, installing the product to its tested details.
Community buildings like Church of St Vincent are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. Letting a property close to Baldock station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Surface by surface
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. We follow the manufacturer’s tested detail for each and we flag any that need another system.
Masonry and concrete
For masonry and concrete, we use a product tested in that substrate. We clean out dust and debris before sealing so the seal has something sound to bond to.
Do you need fire rated sealant in Newnham?
Movement in the structure can open gaps too: a seal that cracks or pulls away leaves a path for smoke. Damage from cleaning, knocks and maintenance adds to it.
It’s worth asking for a quote if you see:
- Sealant items on a fire risk assessment action list
- Old fire sealant that has split or come away
- Gaps left after a refit or conversion
- Ordinary sealant used where a fire-rated product was needed
For site and facilities teams at buildings such as The Knights Templar School, fire-stopping around service openings should be restored whenever new services go in.

Landlords, agents and businesses in Newnham
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Hotels need rooms back in use, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Keep the record of products and locations with your fire safety documents
- Look in service cupboards and ceiling voids from time to time
- Keep photos of seals that will be hidden
Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.
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.
How the visit works
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a handful of gaps, and longer for a whole building. Somewhere like Newnham needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- 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
- Clear items away from the joints we’re working on
- Tell us if parking is tricky
- Keep pets and children clear of the area while we work
Ask for a quote

What happens if it’s left?
Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, so we follow the maker’s details on every gap. Where a wall is exposed, as many are in small places like Newnham, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start.
