Commercial buildings in Alverstone

For seaside hotels, guest houses and holiday lets around Alverstone, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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’re given, installing the product to its tested details.

For buildings such as All Saints' Church, gaps around pipes and cables are worth checking after any building work there. If you look after a building such as Newchurch Primary School, fire-stopping around service openings should be restored whenever new services go in.

Fire rated sealant in Alverstone

In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. We seal them with a product tested for that kind of gap. If you’re dealing with fire stopping disturbed by later work and door frames with gaps between frame and wall, we can help, on flats & HMOs, service penetrations and pipe & cable gaps alike.

For a small place like Alverstone, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.

Every job comes with our one-year guarantee.

Quotes for fire rated sealant in Alverstone

Some jobs are bigger than they look, and some smaller. The main factors:

  • The product the joint needs
  • How many rooms, windows or areas are involved
  • Whether old sealant or filler has to be cut out
  • How easy the joints are to reach

Doing several joints on one visit generally makes better use of the time than several visits. You’ll get one clear quote for the whole job.

What to tell us for a quote

Photos help, but a description is a good start. Please mention:

  • Any access issues, like height or stairs
  • The address or postcode of the job
  • If it’s domestic, commercial or a hotel
  • Whether it has been sealed before

For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will explain what’s involved and send you a clear quote.

What we cannot put right

We will not take on work that won’t last, so here’s what sealant cannot put right:

  • Fire risk assessments, which need a qualified assessor
  • Large holes that need a different fire-stopping system
  • Construction that does not provide fire resistance on its own

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

Joints and surfaces we work on

  • Service penetrations
  • Door frames
  • Pipe & cable gaps
  • Plasterboard & masonry
  • Linear gaps
  • Flats & HMOs

When to call us in Alverstone

Many open fire-stopping gaps are made after the building is finished. Electricians, plumbers and data installers drill through walls and ceilings and the hole they leave doesn’t always get resealed.

Any of these means the joints need attention:

  • Seals cut through by electricians, plumbers or data installers
  • Open gaps behind door architraves
  • Open holes round services passing through fire walls
  • Cracked or shrunken fire-rated sealant

For landlords with property near Sandown station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

What to look for in a quote

  • How much experience the applicator has
  • Are they insured?
  • What happens if the job turns out different
  • How long the guarantee is

Choosing a sealant specialist

What happens on the day

A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Alverstone, the journey is planned in advance: 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.

  1. Before starting, we go through the specification or action list with you.
  2. We measure every gap and note what it’s in and what passes through.
  3. Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. Every location is recorded with the product used for your files.

How to prepare

  • Let us know about earlier repairs to the joints
  • Mention any tricky access
  • On commercial sites, let us know about site rules

DIY sealant or a professional job?

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

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.

FAQs for Alverstone

Will you come out to Alverstone?

Yes. Alverstone is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Is Alverstone in your area for fire rated sealant?

Yes, Alverstone is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.

Will you leave a mess?

Very little: the area around the joints is protected first, and we tidy up before we go.

Will the old sealant be removed?

Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

Do I have to be there?

It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.

What do you need from me for a quote?

A short description and the location, plus pictures if you have them. If we need more, we’ll ask.

I’m a tenant. Can you help?

We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.

Do you hold any approvals?

Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.

Aftercare tips

No joint lasts for ever, but care makes a real difference. A few tips:

  • Never patch a fire seal with standard sealant
  • Take pictures of fire stopping before ceilings or boxing go back
  • Look in service cupboards and ceiling voids from time to time
  • Ask which product was used before you paint

Avoid covering a sealed gap with anything that is not part of the tested detail. If it needs repair, use the same type of product. We can tell you which product we used.

It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes.

Different surfaces, different methods

Linear gaps

Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement from the manufacturer’s details.

Door frames

We deal with the gap around the frame, not the door. The door leaf, its seals and closer need a door specialist, and we’ll say if we spot a problem with them.
