Commercial buildings in Chackmore

Chackmore has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed. 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.

Schools such as St James and St John CofE Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. For buildings such as Parish Church of St Mary, gaps around pipes and cables are worth checking after any building work there.

Fire rated sealant for homes and businesses in Chackmore

Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it. If you’re dealing with unsealed gaps around fire door frames and open holes round services passing through fire walls, we can put it right.

For a small place like Chackmore, the journey and timings are agreed in advance, so it can be fitted around guests, clients or events where possible.

All our work comes with a 12-month guarantee.

DIY versus a professional finish

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

Keeping the joints in good condition

Looking after new joints is easy, and it makes a real difference:

  • Include fire stopping when you schedule refits
  • Make resealing part of every contractor’s brief
  • Never patch a fire seal with standard sealant
  • Check whether a sealant can be painted before decorating over it

Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some can’t.

A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record.

Landlords, agents and businesses in Chackmore

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.

Landlords and agents in Chackmore can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for.

The process

There’s no need to move everything out, just the space around the work. We protect the rest, and the work takes from a few hours to a few days, depending on the number of gaps and the access for a typical job. For a village or hamlet like Chackmore, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. We measure every gap and note what it’s in and what passes through.
  3. Any non-fire-rated filler is removed and the faces cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. We hand over a list of locations and products for your records.

Before we arrive

  • Keep children and pets away from the work area
  • Let us know about earlier repairs to the joints
  • Clear items away from the joints we’re working on

Chackmore questions

Do you work for hotels and guest houses in Chackmore?

Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.

Is Chackmore in your area for fire rated sealant?

Yes, Chackmore is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.

Can you do several jobs on one visit?

Yes. Just list everything you need.

What information do you need?

Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or send us an email.

Are you fully insured?

Yes. We are fully insured, and we can confirm the details when we quote.

Can new sealant go over the old?

No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.

Do you certify the fire stopping?

We don’t issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves, and we install to them.

Can you match the sealant colour?

Yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before we start.

What happens if it’s left?

Sealant is not the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap isn’t suitable for sealant, we’ll tell you. Older cottages and farmhouses around Chackmore can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.

When it is not the sealant

To be straight with you, there are a few things sealant will not fix:

  • Assessing a building’s fire safety
  • Sign-off of the building, which sits with building control or your assessor
  • Construction that does not provide fire resistance on its own

If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.
