Common questions in Letchmore Heath
Do you cover smaller places like Letchmore Heath?
Yes, Letchmore Heath is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Radlett station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
What do you need from me for a quote?
A short description and the location, with pictures by email if possible. If we need more, we will ask.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Is there a guarantee?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
Can you tell me which gaps need fire stopping?
No, we don’t assess buildings. Once you have a specification or action list from your assessor or designer, we can quote for the fire-rated sealant items.
Do you provide details of the products used?
Yes. We note each location and the product that went in so it’s there for the next inspection.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Plan fire stopping into any work that goes through walls or floors
- Report cracked or damaged seals as soon as you notice them
- Keep photos of seals that will be hidden
- Make resealing part of every contractor’s brief
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.
Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole and the job gets bigger.
Leave it or put it right?
Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, and we work to the product details every time. Around Letchmore Heath, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the amount of work, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.

- Old sealant always removed completely

Fire rated sealant around Letchmore Heath

For site and facilities teams at buildings such as Fair Field Junior School, service openings in fire-resisting walls need checking after any refurbishment. If you look after a church, hall or community building such as Church of St John the Baptist, service openings in its walls need the right fire-rated sealant, as in any building.

What we are called out for in Letchmore Heath
Gaps also open up as buildings move: a seal that cracks or pulls away leaves a path for smoke. Damage from cleaning, knocks and maintenance adds to it.
The problems people normally mention when they call include:
- Open holes round services passing through fire walls
- Gaps left after a refit or conversion
- Gaps flagged on a fire risk assessment
- Seals cut through by electricians, plumbers or data installers
For landlords with property near Radlett station, any gap left by new services in shared walls should be closed with a fire-rated product.

Advice
How the job changes by surface
Door frames
Frame gaps are usually hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size before the trim goes back.
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. The sealant has to be one tested in plasterboard for each gap size.
