About our fire stopping in Newtown Common

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, call the office on 01277 525 020 or email drawings and photos with the schedule or marked-up drawings and the specified product data. Tell us what records you need and we’ll confirm with the quote. We work on small duct penetrations where the tested detail allows, service gaps in risers and cable penetrations, and the failures we’re asked to look at most are fire seals cut back for extra cables and never reinstated and service penetrations left open after M&E works. Whoever orders the work in Newtown Common, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Rural conversions around Newtown Common can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Should maintenance staff do it?

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

When it isn’t the sealant

Honesty saves time and money. Fresh joints won’t solve:

  • Signing off or certifying a building’s fire stopping
  • Plastic pipes whose detail calls for a collar or wrap
  • Gaps in walls that were never built as compartment walls

Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we’ll tell you honestly.

What we seal

  • Joints between fire-resisting walls and floors
  • Pipe penetrations
  • Cable penetrations
  • Linear gaps at wall heads
  • Service gaps in risers
  • Small duct penetrations where the tested detail allows

For managing agents and facilities managers

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules.

What affects the price in Newtown Common

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • The site’s rules and procedures
  • The size and state of each joint
  • Which sealant the job calls for
  • Removal of failed or old sealant

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

What we need to price the job

However big the job, the same details help:

  • Photos of the joints, close up and from further back
  • Specification clauses that apply
  • Approximate linear metres or a joint schedule
  • The postcode of the building

Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. For a chat about it beforehand, ring 01277 525 020 or email drawings and photos.

When to call us in Newtown Common

When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.

What tends to prompt an enquiry:

  • Fire stopping installed outside its tested range
  • Unsealed joints where partitions meet the slab
  • Openings found when ceilings come down for a refit
  • Fire-stopping items raised at inspection or handover

In a school such as Horris Hill School, fire-rated sealant goes in around service penetrations where it is specified.

Questions to ask before you book

  • Their approach to joint depth and backing
  • Their pre-qualification and accreditations
  • Proof of insurance
  • Whether primer will be used where the manufacturer specifies it

Is the work guaranteed?

Yes. Our workmanship is backed for 12 months on every job.

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
