Leave it or put it right?

Fire-rated sealants are less forgiving than ordinary ones. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. In a small place like Chalkhouse Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

Why book with us

  • We leave the area clean and tidy

DIY versus a professional finish

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

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.

What sealant work can’t fix

Before you book, it’s worth knowing the limits too:

  • Deciding what fire stopping a building needs
  • Problems with the door itself rather than the gap around the frame
  • Certifying a building or signing off its fire safety

If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before booking.

The process

On the day, we start by going over the job with you. Surfaces next to the work are protected before any work begins. The work generally takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere as small as Chalkhouse Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. Old, damaged or unsuitable sealant is removed.
  3. Gaps are cleaned of dust and loose material.
  4. We apply and tool the sealant to the product’s tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Getting ready for the visit

  • For business premises, tell us about site rules or sign-in
  • Move anything stored near the joints
  • For indoor joints, keep the area dry beforehand if you can

Keeping the joints in good condition

To keep the joints looking good and working properly:

  • Include fire stopping when you schedule refits
  • Get damaged fire seals looked at promptly
  • Check risers, ceiling voids and cupboards during building checks
  • File the fire-stopping record where your assessor can find it

Don’t drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.

FAQs for Chalkhouse Green

Do you cover smaller places like Chalkhouse Green?

Yes. Chalkhouse Green is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Can you do fire rated sealant in Chalkhouse Green?

Yes. We work across London and the South East, and Chalkhouse Green is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we will give you a clear price.

What fire rating will the seal have?

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.

Do you remove the old sealant?

Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.

Can you match the sealant colour?

We’ll suggest a colour to suit the surroundings. The choice depends on the product the joint needs.

Do you guarantee your work?

Yes: twelve months. If there’s a problem with our work in that time, tell us and we will put it right.

Do you work in flats, HMOs and commercial buildings?

Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. The order of work and access are planned with you.

Do you seal gaps around fire door frames?

Yes. The joint between frame and wall is sealed with a fire-rated sealant following the tested details. The door, its seals and closer are for a door specialist.

Fire rated sealant in Chalkhouse Green: local notes

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, and gaps around services are often picked up there. 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 Saint Barnabas Emmer Green, gaps around pipes and cables are worth checking after any building work there. For site and facilities teams at buildings such as Emmer Green Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. If you let a flat or house near Reading station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

How the job changes by surface

Flats and HMOs

Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified room by room.

Service penetrations

Different services need different details: metal pipes, cables and plastic pipes aren’t treated the same. Each one is sealed to the product’s tested detail, and tell you if sealant alone is not the right fix.
