For over 35 years I personally have been involved in the residential and commercial construction trades. Our background & experience covers building science education health & safety. In addition, weatherization, thermal / air barriers / HVAC / mechanical / electrical / gas fired appliances / moisture / air leakage / CO2 & CO / dirty air / water sheds / glazing areas / green buildings / energy management / solar loading etc. The list goes on.
Our inspection services can include additional services such as building pressure testing and flue draft measurements. Want to know more about the building structure you are buying?
We operate within Oregon's SOP, "standard operating procedures". However if the client desires a more professional technology inspection we can provide it as well. In order to provide building pressure testing requires additional certifications and training. Why pressure test? Pressure testing will tell a little more about the duct pressures. Measuring dominant positive or negative pressures. See our page on pressure testing.
Flue Draft Testing. While all inspectors may or may not test flues of combustion appliances, again there is a reason why. Why is this important? Flue draft of combustion appliance should be a requirement. Because 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 heat and cooling utilizing thermal imagery. Thermography is tricky if you are not trained in this field. This is why they provide training. 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.
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 very big concern. Many people are injured every year to 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 provide several types of inspections.
SOP / Oregon: Standard inspection of interior and exterior.
Add Ons: Testing of combustion appliances, testing of flue drafts, insulation varification R-value.
Commissioning: This is for new construction on structures that have been 100% complete. Potential buyer may want the structure inspection to verify all electrical, water systems, plumbing, HVAC, receptacles, lighting, mechanical, structural, roofing, appliances, pressure testing, ventilation, vapor barrier, thermal barrier, insulation, air sealing, etc.... has been installed correctly and working. Before moving in varify!
Commercial: New or existing structures. Please contact us.
Building inspections. Potential buyers or occupants depend on a professional company to uncover possible issues for health and safety. We follow the SOP standards applied by Oregon. However we can expand on conducting a better inspection. On combustion appliances, wouldn't you want to know how efficient those appliances are? Wouldn't you want to know if those appliances "flue" are drafting correctly once the structure is placed under load? Under load means, all exhaust fans in the structure on!
By placing all exhaust fans on, this may create a negative pressure within that structure. If the negative pressure reach's 3 pacals "PA" this would pull the CO gases back into the structure. Many people do not know this and rely on CO detectors. However when you read the instructions on a CO detector it tells you how high the CO level must be before it will alarm. On some CO detectors the level PPM has to reach a level that could kill a person before it alarms.
From the attic to the crawlspace, we inspect the whole home and property. All the major systems and components will be inspected. The list below is what you need inspected before you make one of the biggest purchases of your life.
Systems Inspected Include:
- Structure: foundation, framing, roof , walls, crawlspace and attic
- Roof: eaves, gutters, downspouts, vents, chimneys and all vent stacks
- 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 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
Industrial-Commercial Inspections: Industrial inspections / audit cover the structure as well as equipment. An energy audit covers machinery, electrical loads, lighting, thermal / air barriers, HVAC systems. These audits may take a few days to weeks depending on the size of the building and number of mechanical equipment in place. Commercial & industrial is very different from residential.
These types of facilities have different types of materials used in the building process. Plus the amount of electrical and mechanical equipment takes a great deal of time to test and process. These inspections include a spread sheet report outlining existing energy usage compared to what could be reduced when upgrades are implemented. Along with a narrative report outlining any defectencies we locate.
We offer building pressure inspections if you have gas fired appliances or an chemical storage room. We place the structure under load so testing results will reveal real life exposure to back drafting of CO or other types of C02. Yes we use scientific equipment to conduct these tests. To the best of my knowledge no other home inspection companies offer this procedure.
