Oregon Home Inspection

 The owners of Building Analyst Group Inc, has been in the building trades for 35 years and serving the Pacific Northwest for 18 years. Our knowledge of the building envelope "structure" is top of the line. We pay attention to detail and know what to look for. Testing a home or building can really define issues. However the Oregon SOP does not require testing and only visible requirements. 

Yes we offer the same inspection proceedures as the other 200 home inspectors in Oregon. However we can also include more services in addition to inspections. We feel it is important for a home owner to know what they are investing in.    

What makes us different? Our background & education in installing HVAC systems, duct work, electrical, ventilation, insulation, thermal and air barriers, framing for over 30 years. Include energy management, environmental, health & safety, air quality, and building science.  

 From the attic to the crawlspace. All major systems and components will be inspected. 

Inspection Include: Standard Operating Procedures for Oregon.

  • Structure: framing, roof , walls, crawlspace and attic
  • Roof: eaves, gutters, downspouts, vents, chimneys and all vent stacks
  • Foundation: The foundation is the backbone of your home
  • Electrical: Outlets, light fixtures, switches, main panel/sub-panel, service entrance conductors
  • Plumbing: Water heater, visible piping throughout home, all exterior and interior faucets, sinks, tub/showers
  • Heating and Cooling: Main furnace, oil / wood/pellet / gas stoves, ducting, A/C unit and lines
  • Exterior: Walls, siding, patios, decks, walkways, garage door, exterior fixtures and outlets, windows and doors
  • Ventilation: Attics and crawl spaces need to be properly vented
  • Vapor Barriers: Crawl spaces should have proper ground barrier
  • Interior: Ceilings, walls, floors, drywall, finishes, windows, doors
  • Insulation: Attic insulation and venting, crawlspace insulation and venting
  • Appliances: Dishwasher, ranges, waste disposal, permanent microwave

 Add on's: These additional services may take several hours to complete. There is an extra charge to analyze and test. In order to analyze, test and document the below services scientific meters and devices are used. These services if conducted should be ran in conjunction with a inspection. Depending on the size of the structure will determine the time needed. We highly suggest having the additional services conducted if your building has gas or oil fired equipment. 

 

  • Weatherization inspection, thermal imaging and visual inspection
  • Thermal & air barriers, visual inspection
  • HVAC, air flow metering equipment is used
  • Mechanical, spas, whole house fans, compressors
  • Amp loads, metering devices are used to measure electrical devices
  • Gas fired appliances efficiency testing "combustion analyzer" & gas leak detector meters are used
  • Flue draft testing, a manometer is used
  • Building pressures, digital manometer is used
  • CO2 & CO / dirty air, digital metering
  • Radon electronic testing

Our services could include a detailed inspection of the SOP and "EM" Energy Management detailed list. To the best of my knowledge no other inspectors in Oregon are certified in these areas . We have been testing and analyzing these areas of the building envelope for many years. 

When investing several hundred thousand of dollars in a property, I would want to know how much more am I going to have to invest after the purchase. Yes a standard inspection does cover major components such as plumbing, foundation, electrical, structural and roof. However think about long term utility cost health & safety.

  • What if my electric bill is $300 or more per month after I move in?
  • What if the back bedroom is cold in the winter or hot in the summer?
  • What if I feel drafts on my feet?
  • What if my family starts to feel sick because of CO? 
  • What if my home fills up with smoke from my chimney?
  • What if I find out my home has radon?

 

 

Combustion testing for efficientcy and flue draft. 

Thermal imagery of electrical.

Flue Draft Testing. While all inspectors may or may not test flues of combustion appliances, again there is a reason why. Flue draft of combustion appliance should be a requirement. When a structure is under negative pressure the flue gases that are suppose to go out the flue. Negative pressure will pull CO back into the living space. Or if there is a fireplace that smokes up the structure, negative pressures could be the reason why in most cases.  

Thermal Imagery: Years ago we were certified by FLIR in thermography.  The science of "conduction" heat and cooling utilizing thermal imagery. Thermography is tricky if you are not trained in this field. This is why professional training is provided. Before reporting on an inspection when using this technology, the inspector should know what they are talking about. Yes we provide thermal scanning on electrical and the building envelope. Non evasive thermal scans can be a instrument used in detecting over heated circuits, water or moisture intrusion, air leaks, etc.

Certified by BPI-Building Performance Institute has also provided us with a much better understanding on building science, energy usage and testing for health & safety. Here in the Pacific Northwest we also have PTCS-Performance Tested Comfort Systems certification for duct systems. This program was designed by Bonneville Power and Energy Trust of Oregon. This involves HVAC duct systems and building pressures. As you will read in our web site building pressures can be a very big concern. Many people are injured every year by having negative pressures in their dwelling with gas fired appliance. Many businesses have experience health and safety issues with chemical storage rooms due to improper pressures.  

We use many types of scientific equipment to accurately test and measure pressures. Many types of tests can be conducted with manometers. Did you know within ten minutes we can tell you which side of your duct system is leaking more than the other side. Supply & return. 

Building pressures greatly increase possibilities of higher energy usage, back drafting of CO & CO2.

Also high negative pressure can cause fireplaces to smoke up condition spaces. In commercial buildings high negative pressures can cause dangerous fumes / gases / germs  to enter areas of the building where people visit or live.  


PTCS - Performance Tested Comfort Systems. For years we have installed, tested and sealed duct systems. By doing so saves a great deal of energy and creates better climate zones in the structure. We are also certified as a trainer in this trade.

Combustion appliance zones covers areas of the structure that has gas fired, wood burning or oil fired equipment. I would consider this information and training to be educated across the board to all contractors that work buildings that have combustion or chemical storage equipment.

Building envelope covers the entire structure inside and out. This training educates on the principles of how to investigate a dwelling or structure on energy loss and how to implement a program to save energy. Testing structures by using a blower door and duct blaster developes a set of numbers of how leaky that structure is. After repairs have been completed another test is done to see the improvements.

Thermography, infrared technology to see high or low temperatures in materials such as walls, wiring, ground, motors, electrical devices.  Its up to the thermographor to read or develop these reports on a professional level. If not trained correctly false or misleading information can be dangerious or costly.
