Why you might need an inspection service

There are four main reasons why we carry out inspections:

  • To ensure work is carried out to the required standard
  • To identify where and why a property is losing heat
  • To assess the condition of existing insulation
  • To assess whether a property is of the right structure and in the right condition to have insulation installed

We carry out these inspections:

  • As part of the BBA’s Installer Approval and Inspection Service
  • To check the condition of your home or a house you are interested in buying
  • Before every installation or extraction we undertake
  • To ensure our own team consistently meet our exacting standards

Inspecting your home

If your home has unexplained damp and mould we can inspect your property and identify what is causing the problem.

Even if your property has no outward signs of damp you may:

  • Be unhappy with work carried out by another company
  • Find your energy bills are not going down as you expected
  • Feel your property is not retaining heat

We can inspect the condition of your current insulation and identify if and why your home is losing heat.

Heat loss survey

Our heat loss survey will identify if your home is losing excessive heat and confirm the reasons why. We use a thermal imaging camera to highlight any cold spots on your house where warm air is escaping Cold spots will eventually lead to damp, condensation and mould and could be caused by faulty insulation.

Install Check

Cavity wall and loft insulation are designed to protect your home, creating a warm and healthy environment for you to live in while helping to cut your fuel bills. However, your insulation can actually damage your home if it was poorly installed.

The following are all signs of a poor installation and can lead to cold spots and, eventually, penetrating damp:

  • Insufficient ventilation
  • Debris left in the cavity
  • Voids in cavity wall insulation
  • Gaps at the edge of loft insulation
  • Incorrect spacing of the drill holes for cavity wall insulation

The damage caused by a poor installation can take several years to show. So even if there are no outward signs of damp, you cannot assume your insulation is safe.

We can check the condition of your current insulation to see if it was installed correctly. We can also inspect the condition of older insulation as this can also cause problems if:

  • It has degraded so no longer fills the cavity or traps sufficient warm air
  • It has become wet

Pre-install survey

Before we install any insulation in your home we do a thorough survey. This is to ensure your home is of the right structure and in a suitable condition to be insulated. We will never install insulation in a property where it would be unsuitable.

Our inspection is thorough, exceeding industry guidelines and that of many other installers. For example, for cavity wall insulation we look inside every wall in four different places1. We do this using a 360o video boroscope2 that allows us to see two metres in every direction inside the cavity.

The survey covers:

  1. The type of property and the cavity construction
  2. The location of the property
  3. The age of the property
  4. The width of the cavity
  5. The condition of the wall ties
  6. Detailed visual inspection within the cavity investigating area to be filled
  7. Detailed visual inspection of the external wall area of the wall/s to be filled
  8. The condition of the structure for damp or condensation issues
  9. The services through the cavity which would be affected by cavity fill, e.g. ventilation, gas flues, etc.
  10.  A Health and Safety risk assessment report

If you have a grant for your insulation we will also ensure you have an energy performance certificate (EPC). Our chartered building surveyor will then sign-off the measures recommended in the EPC. This will confirm that your property is suitable for the proposed insulation installation.

Inspecting a home you want to buy

Investing in a new home is one of the most important decisions you'll ever make

Although it is now a requirement that anyone selling a home has an energy performance certificate (EPC) and a valuation report for the property, this will not identify any potential problems with existing insulation.

Under our Check Before You Buy service, we’ll inspect your potential new home to be sure it’s not hiding a long-term problem with penetrating damp.

Inspecting our own work

The BBA require that 5% of all installations funded via an energy company (as part of a government grant scheme) are monitored by a third party inspector. This is the only way many companies monitor the quality of their own work.

There is also currently no requirement for these independent inspectors to be assessed themselves.

By contrast, observation and inspection are the norm throughout our company. We inspect 100% of extractions and 50% of installations, however they are funded. In addition, our directors, Gary and Paul, regularly undertake unannounced inspections to ensure our technicians consistently maintain the high standards they have set.

Inspecting other people’s work

We are part of the BBA’s Installer Approval and Inspection Service. This means we act as a third party inspector for installations funded (or part-funded) with an ECO grant from an energy company, under the government-backed scheme.

Other reputable companies also ask us to undertake third-party inspections of their teams.

We inspect the installing company’s vehicles and equipment and the installation itself:

  • As the site is prepared
  • As the work is carried out
  • Once it is complete

We check that:

  • The appropriate health and safety procedures are in place
  • The correct specification for the installation is met
  • The work is carried out to a satisfactory standard

  1. The BBA’s best practice guide recommends two boroscope inspections for each elevation.
  2. Most insulation installers use a rigid boroscope that only gives a ½m view.
