Serving Nepean Homes and Businesses
Nepean is one of Ottawa’s most established communities, with homes spanning from post-war bungalows built in the 1950s through to subdivisions constructed in the late 1990s. That is close to five decades of residential construction, and each era came with its own insulation standards, most of which no longer meet today’s efficiency expectations.
In neighbourhoods like Carleton Heights, Fisher Heights, and Arlington Woods, attic insulation often has compacted or degraded over the decades, leaving homeowners with heat loss they can feel every winter. In Centrepointe and the Merivale corridor, where development came later, homes may still benefit from improved air sealing and higher insulation levels.
Whatever era your home was built in, chances are we have worked on one just like it right here in Nepean. We know what to look for, we know how to address it properly, and we use only eco-friendly, formaldehyde-free materials to do it.

Frequently Asked Questions
The cost of attic insulation depends on the size of the home, current insulation levels, attic accessibility, and whether old insulation needs to be removed first.
For many Nepean homeowners, upgrading attic insulation is one of the most cost-effective ways to improve comfort and reduce long-term heating and cooling costs.
Most attic insulation upgrades today aim for approximately R-60, depending on the structure of the attic and the condition of the existing insulation. Many older Nepean homes were built with significantly lower insulation levels than what is recommended today.
Uneven temperatures, rising energy bills, drafts, cold floors, and rooms that are difficult to heat are all common signs. In older homes, attic insulation can settle or compact over time, reducing its effectiveness even if insulation is still present.
Not always, but many older homes benefit from improved attic insulation, air sealing, or targeted upgrades in problem areas. Homes built decades ago were constructed under different insulation standards, and performance can change over time as materials settle and renovations are completed.
Yes. Drafts and uneven temperatures are often caused by heat loss and air leakage around attics, exterior walls, crawl spaces, and other areas of the home. Proper insulation and air sealing can significantly improve comfort and temperature consistency throughout the house.
Attic insulation can last for decades, but its performance may decline over time due to settling, moisture exposure, age, or previous installation quality. In many cases, insulation can be topped up rather than fully replaced, depending on its condition.
Most residential insulation projects are completed within a single day. Larger projects involving insulation removal, mold remediation, or multiple areas of the home may take longer depending on the scope of work.
