Common questions in Porchfield

Will you come out to Porchfield?

Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Do you cover Porchfield for fire rated sealant?

Yes. We work across London and the South East, and Porchfield is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.

Do you carry out fire risk assessments?

No. That’s for a fire risk assessor, designer or building control. Our job is applying the sealant to their specification.

Can you match the sealant colour?

Usually, yes. White, clear and grey are common, and other colours are available for many products, and we’ll agree it with you first.

I’m a tenant. Can you help?

Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.

Can ordinary silicone be used in a fire-stopping gap?

No. Ordinary silicone, caulk or foam isn’t tested as fire stopping. If it’s been used, we remove it and use the right product.

Do you certify the fire stopping?

Ratings and certification sit with the product’s test evidence and whoever specified the work. We apply the specified product to the manufacturer’s details and giving you a record of where it went.

Is there a guarantee?

Yes. Every job comes with a one-year guarantee.

About our fire rated sealant in Porchfield

Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. If you have gaps flagged on a fire risk assessment and linear gaps at the head of walls, we can put it right, on linear gaps, plasterboard & masonry and pipe & cable gaps alike.

In a village or hamlet like Porchfield, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

Whatever the size of the job, you get the same 12-month guarantee.

Should I try it myself first?

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

Common problems we fix in Porchfield

Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. We see plenty of fire stopping that was hurried particularly when it was the last job before handover.

People usually contact us when they notice something like this:

  • Linear gaps at the head of walls
  • Gaps around pipes and cables through fire-resisting walls
  • Damaged fire sealant left by other trades
  • Gaps filled with a product that is not fire-rated

Around Porchfield, as everywhere, fire rated sealant is only as good as the preparation behind it.

Questions to ask before you book

  • Are they insured?
  • How much experience the applicator has
  • What product goes in the joint
  • What preparation is included

Our hiring checklist

How the job changes by surface

Linear gaps

Gaps along the top of partitions are easy to miss above a ceiling. We work along the whole run.

Door frames

A door can only do its job if the gap behind its frame is sealed too. We fill it with a fire-rated product suited to the materials either side.

Work for landlords, hotels and businesses

Letting agents often deal with us directly. Tell us the address, the job and how access works.

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

What happens on the day

We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Somewhere as small as Porchfield, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. Each gap is measured and its substrate and service noted.
  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.

Getting ready for the visit

  • Try not to wet indoor joints just before the visit
  • Mention any leaks or damp you’ve noticed
  • On commercial sites, let us know about site rules

Getting a quote

There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or drop us an email.

Advice

Fire rated sealant around Porchfield

For seaside hotels, guest houses and holiday lets around Porchfield, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. 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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Whether the job is in Porchfield itself or nearby, the right material for each joint matters as much as a neat finish.
