Attic insulation is a material installed within your roof either between rafters or joists. Its primary purpose is to slow down the transfer of heat between your house and the outside world. The end result is a cooler house during summer and a warmer home during winter. Other benefits that you will get by installing loft insulation are:

  • You will improve your homes energy rating

  • You enjoy reducing heating and cooling bills

  • You increase the resell value of the home

Most companies in Victoria BC will only tell you to get your loft insulated. However, they will not go out of their way to tell you why it should be protected. Before you consider insulating your attic, we advise you to get familiar with our "Attic Symptom Checker."


If you identify one or two of the following symptoms, then you should call us immediately:

  • The roof has icicles

  • There is moisture in the ceiling

  • Your home is too warm during the summer

  • The floor feels unusually cold

  • Your energy bill is all of a sudden high

  • The temperature in your attic is higher than that of the outside environment

  • The home feels drafty

  • There is frost in the attic

If you see one or two of the following options, give us a call, and we will provide a free attic evaluation. During the assessment, expect one or two of the following:

  • Q&A

  • A full attic inspection

  • Identification of any deficiencies

  • A recommendation report

  • Free Quote

A qualified attic insulation company should understand the importance of a ventilation system in the attic. A well-ventilated attic will reduce the amount of damage caused by trapped moisture, thereby preventing the property owner from incurring costly repairs.

We might recommend an insulation upgrade if you have already had one installed. The recommended attic insulation R-value should be R-40. If your sealing material is below this, then an upgrade is required.

A professional company should not upgrade the attic without checking for any air leaks because the leaks may cause leakage, increasing humidity levels in the attic, or even result in a critter infestation. A well-ventilated attic has the following summer benefits:

  • Excess heat is expelled, reducing the strain on your air conditioning machine

  • Reduces mildew and wood rot that is usually a result of moisture build-up in the bathroom and kitchen


During winter, your attic should offer the following benefits:

  • Reduce the risk of ice dams forming

  • Reduced chances of having wood rot, mildew, and mold

Note: If your house has no insulation, then it loses a quarter of its heat through the roof.


One main advantage of why we encourage residential property owners to have attic insulation is that, unlike other sealing materials, this can last for more than 40 years without needing any upgrades.  The secret to loft insulation depends on the kind of thickness installed. The thicker it is, the more the saving effect.
