1950's worl trade house complete with vintage bomb shelter and green building principals.


Look for the Fiske/Lau project for photos of our completed work.
This project was recently entered into a AIA North West region readers choice award after an artilcle featuring it in Willamette Living Magazine.


All contracts signed with G. Christianson Construction are due to be completed on or before Dec 31st 2010.

We are still actively bidding and completing jobs to allow the best use of these incentive changes before the Dec 31st Deadline occurs. As we are not aware of the new changes that are coming it would be in your best interest to act before they happen.

CWIP representitives were on hand at the Energy Trust roundtable event yeaterday to let companies know that there are still funds available for individuals within the Corvallis area who meet the criteria for weatherization upgrades.

There is still time to get an addittional $500.00 per household for this incentive. Remeber that these incentives are paid dirrectly to weatherization contractors who are registered with their program. This incentive eligibility is based upron Energy Trust criteria and includes many upgrades that add efficiency to an older home. This is am amazing opportunity offered to anyone within the Corvallis City Limits and is expected to change to some extent on Dec 31st when new incentive payback amounts go into effect.

Act Now!! This program is a fantastic way to offset the cost of weatherization upgrades to Your home.

Yesterday the Energy trust had a roundtable event to discuss new changes in the weatherization industry in Oregon. As the current rebate incentives are due to change on Dec. 31st 2010 many are wondering what the new incentives will be and how weatherization will be effected.

As of yet these changes have not been released but we will keep you informed as they are released to Trade Ally programs.

Remember that CPI and ETO as well as many of the federal tax rebates are set to expire on December 31st. Time to weatherize while passing the cost along is nearing its end. I hope to see future tax credits retuen for these programs but as of yet the future funding is uncertain and unclear. Many changes have been in the works for these programs and incentives have already begun to lessen for rebates. Now nearly every program looks to access what other money is out there available and the cost of installation is lessening by factoring in the final cost after rebates have been accounted for thus lowering final incentives to the homeowners.
Act while you still can as there has never been a better time to upgrade your homes efficiency while saving money doing it.
Our goal is not to justify our weatherization sales, but to walk you through the choices available to you to allow you the ability to make an informed decision on your options for home comfort improvement.

A recent client of ours opted to use us for duct sealing and blower door testing but thought they would save money by doing the insulation portion themselves and contracting dirrecly with a sub contractor. When the insulation company showed up to do the work however, is was realized that several key items were missing from their origional bid that ours had included. Luckily these things were able to be added in while the work crews were there but at extra expense. The final cost of the job came very close to our origional contract price.
If your estimaters are not going into the crawlspaces and attics and physically looking at the jobs in detail, most of the estimates they give you will allow them to leave out items that can be added later to bring the final price up.
As a Contractor: we will stand behind any work we are contracted to do with you dirrectly. If we need to replace a subcontractor to ensure the work is done correctly and to our standard, you can be certain that it will happen.

Here is a link for an ask the builder column that explains a bit more about the importance of venting these crawlspaces and leaving foundation vents open.


While driving around and giving bids to many folks who are looking to take the edge off their winter heating bills, I have seen a large number of people who seem to think that foam blocking their foundation vents is a good idea in regards to weatherization. While it would go to reason that any blockage of cool air in or under the house may increase comfort and lessen the heating load, it should be stressed that covering foundation vents is a horrible idea in Oregon or any cool wet climate. Foundation vents are meant to allow air to evaporate the moisture within the crawlspace areas. Nearly every crawlspace I have seen has some sort of moisture problem. Energy trust and most incentive programs require a vapor barrier in these areas to help contain the moisture within the ground. Building Codes have long stressed the importance of vapor barriers in these spaces as well.
What happens when you trap the existing moisture from these areas within the building cavity or crawlspace and do not allow proper airflow to help remove the moisture? Imagine dumping a cup of water in your refrigerator and sealing it closed for a few months! Mildew and mold are often seen in these situations and can lead to serious health problems and increase many other problems that are often seen such as dry rot within the sub floor and framing.
Remember that your insulation is your thermal barrier for the house. Not your crawlspace vents!

Here are examples of some weatherization in progress.
Im always amazed at the improvements that can be made to these systems.
