Use Durable Materials

Using durable materials lengthens the amount of time before there is a need to replace and discard old materials to a landfill.

Solar Panels

For this project, we helped design and install a system that install a system that includes 40 solar panels. This saves 11 tons of carbon pollution per year, and provides about $1,500 savings per year. Super insulation. Energy-efficient appliances. No drafts or thermal bridging. At G. Christianson Construction, our energy-efficient approach makes it possible to maintain a stable, comfortable temperature in your home with less energy, at less cost.

Tips for Building a Solar Electric Home »

Remove Your Chimney

Chimneys are dangerous during natural disasters, and also leak a tremendous amount of heated air out of the home. We recommend removing or sealing your chimney.

Air Tight Windows & Doors

If your home is uncomfortable, drafty, or cold, you should consider upgrading your windows and doors to be air tight. It can also reduce your home’s carbon footprint. We can block drafts, help you select low-VOC materials, and incorporate systems that will lower your utility bills, improve air quality, and add to your comfort.

Add Ceiling & Underfloor Insulation

Lack of insulation in the attic is the number one cause of energy loss in a home. We can offer air sealing and insulation solutions to increase the comfort and energy efficiency of your home. Underfloors are also a major source of heat loss, and supply crawlspace air into your home.

Indoor Air Quality

In a leaky older home, unhealthy air is drawn naturally through the crawlspace into your home. We can greatly improve your indoor air quality by air sealing your floors and ceilings, and providing filtered, outside air through a Fresh Air HRV System.

Insulated Exterior Walls

During siding replacement, we always encourage your to add continuous exterior insulation. This prevents energy loss through your wood framing, increases siding durability, reduces air leaks, and decreases moisture intrusion.

Migrate Away from Natural Gas

Electricity can be powered by renewable resources thus reducing global climate change. Electricity also eliminates the risk of gas leaks or carbon monoxide poisoning.

Electric Cars

Electric Cars are easier to maintain, have lower costs, and have no fuel emissions. We can future proof your home by preparing your garage for electric cars and batteries. We can also also fast-changing electrical outlets in your garage.

“We could not have been happier with our experience working with G. Christianson. Super organized. Professional. Super high quality work. Responsive. Kind and generous. We had one point of discussion that was handled quickly, professionally and with equanimity. Our kitchen remodel has changed our home, not only structurally but how we live here. And that could not have been done without the good folks from G. Christianson.”

“They took our period bathroom and built a gorgeous and accessible shower with great sensitivity to the historic details. They left no mess, and finished every detail perfectly. They adapted to small changes we suggested and made errors right. Tony, especially, was just terrific to work with and the cabinetmaker was a master!”
