What we cannot put right

New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:

  • Big openings where sealant alone is not the tested solution
  • Fire doors that need new seals, closers or hardware
  • Certifying a building or signing off its fire safety

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

Joints and surfaces we work on

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

Fire rated sealant for homes and businesses in Hemsted

Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, and we can record what went where. We work on service penetrations, door frames and flats & HMOs, and common reasons people get in touch are joints picked up in a fire-stopping survey and old fire sealant that has split or come away.

Somewhere as small as Hemsted, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.

There’s a 12-month guarantee on every job, large or small.

Surface by surface

Flats and HMOs

Converted houses often have gaps around old and new services. We seal the ones on your specification with a tested product and the locations noted.

Linear gaps

Long, narrow gaps appear where walls meet slabs and ceilings. We seal them to the tested detail, with backing where it’s needed.

Fire rated sealant around Hemsted

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 work to the specification you are given, installing the product to its tested details.

Managing a site like Stowting Church of England Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices. If you look after a church, hall or community building such as Church of St Mary, gaps around pipes and cables are worth checking after any building work there. Letting a property close to Westenhanger station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

How the visit works

Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of gaps, and longer for a whole building. Somewhere as small as Hemsted, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. We put in whatever backing or fill the product detail specifies.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. We record the locations and products used for your records.

Getting ready for the visit

  • Mention any leaks or damp you’ve noticed
  • Tell us if parking is tricky
  • Mention if the joints have been sealed before

Ask for a quote

Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.

Advice

What happens if it’s left?

Paying for fire stopping that has to be redone is a false economy. If the details weren’t followed, the seal may need redoing when the building is next checked. Older cottages and farmhouses around Hemsted can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

Quotes for fire rated sealant in Hemsted

You will get a clear quote before any work starts. It takes into account:

  • How easy the joints are to reach
  • When we can work, for business premises
  • Mould in or behind the old joints
  • The amount of work

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we will explain what it covers.

What to tell us for a quote

Before you ask for a quote, have a think about:

  • Roughly how big the job is
  • Any previous sealing or DIY work
  • The address or postcode of the job
  • What’s wrong with the joints now

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’ll explain what’s involved and give you a clear quote.

Can I do it myself?

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

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