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.

What our Clients are Saying

“The Arc of Benton County used G. Christianson's services for an addition to our thrift store in Philomath. Tanner was our contractor. His attention to detail, preference for quality materials and systems, eco-friendly emphasis and personal contact set the company above its competitors. I would give 4 and three-quarter stars if I could, only subtracting a quarter star because we ended up waiting a long time for a door knob after we were using the space. I like the online messaging platform they use and the schedule Tanner gave us in advance. Construction is generally expensive these days, but G. Christianson was priced fairly for the quality they deliver. Tanner worked with me on some change orders to refine our actual needs in process. I definitely recommend working with them for a stress-free, predictable, and top-quality experience. The addition looks like it has always been there and meets all of our needs. Thank you, Tanner and G. Christianson Construction!”

“We found that G. Christianson has a focus on quality in every detail. This made them very easy to work with and has resulted in a beautiful remodel of the master suite in our home. Tony, the carpenter, in particular made sure every detail he worked with was perfect and made sure the site was cleaned up every day, even when the mess was left by a third party contractor. Thanks to all the team at G. Christianson for the excellent work.”

“Excellent company! Working with G. Christianson Construction was an easy process. Carl Christianson was available and accessible every step of the way. We wanted to work with some of our identified sub contractors and welcomed the professional quality of those provided through the general contractor. Our commercial project was provided the same expert attention of other high end custom projects. Experience, expertise and genuine interest was evident in the professional advice that completed the project within budgeted cost and schedule. HIGHLY recommended!”
