"Yes. Billy said everyone was great on install date. Omar was helpful and communicated effectively. Team worked well together and were efficient. Team was respectful of our property and cleaned up after work done. All of the team members being available was excellent to get install in one day. We hopefully will enjoy the benefits of the insulation and all went as anticipated with install. Very glad we had it done. Leo was excellent with pre install quote and arranging for install. We got a few quotes . We paid highest quote to have the work done quickly which met our needs. Thank you for the excellent service"

"I called and Eric answered immediately without me having to leave a message. They were able to schedule the work in a timely manner and get it done soon. All the workers were courteous and considerate. They cleaned up reasonably well, but we realize that with blown in insulation, it’s tough to clean every bit up. I would definitely recommend them to family and friends!"

"We have a 1970's and we decided to have an energy audit by Landmark Construction. It was clear that our house have some energy issues and was in need of a any type of energy overhaul.  The report that was prepared for us by Charlie and his office staff, was comprehensive, clear to understand and revealed that the ducts at the attic  was not sized appropriately. In addition to that, the furnace/AC in the smaller unit was old (and original) and had to be replaced. The recommendations that Charlie told us, included a new furnace/AC, new tankless water system, hot water pipe insulation, building sealing, the insulation and new ducting throughout the house. This was the best investment we ever made.  I could not believe the difference in our utilities bill.  Charlie and his team were great,  professional and experienced. I wish we did these 15 years ago!!

Insulation questions, answered by experts

Unless your cellulose insulation is wet, moldy, or showing signs of mildew or pests, there’s no need to remove it before adding new insulation on top of it. Inspect your insulation thoroughly before adding the new insulation, and if you’re unsure how to assess the presence of mold or mildew, talk to a mold remediation specialist near you.

Through R-value assessments based on climate and existing insulation.

Vapor barriers in attics are a bit outdated and most areas no longer recommend them for attic spaces. For vented attics, the best method is usually to install drywall and cover it with latex paint before attaching insulation fiberglass, cellulose, or foam insulation. When renovating an attic to use as a living space, a contractor can guide you on the best way to cover insulation.

Fiberglass is considered a favorite garage insulation choice due to its combination of affordability, ease of installation, and overall effectiveness. Fiberglass provides good thermal resistance, helping regulate garage temperatures and minimize heat transfer. Additionally, fiberglass is moisture-resistant, reducing the risk of mold or mildew formation.

One of the disadvantages of soffit vents is they can bleed warm air from the attic during winter, resulting in slightly higher energy bills and a colder house. There are ways to mitigate this effect—mostly just closing the vent in the fall. What’s most important is your attic is ventilated to some degree in the winter.
