Will Dry Ice Blasting Solve Attic Mold the Problem?
House attic mold is one of the most "popular" items in my property inspection reports. And now is time for an explanation of how to kill mold and / or how to clean mold in the attic. But before I do that, let me give you a little advice, something to consider before you sign a few (if you're lucky) thousand dollars contract agreement with a mold remediation company.
Attic mold remediation TIP - an alternative (to consider):
Let us assume that you are in the middle of a real-estate transaction, and the home inspector just revealed to you, that your entire house attic is contaminated with mold.
If you have a brand new roof, you can only blame yourself or try to blame the roofing contractor for not checking the attic before replacing the roof (he will laugh at you unless you've actually asked the guy to check the attic before the roof replacement). If you have an older roof, the importance of this advice is even greater.
Call at least 2-3 mold remediation companies for an estimate - specify to the representatives, that you not only want to have the mold removed, but also attic ventilation system corrected / installed if necessary / ask if the attic insulation requires replacement.
With the numbers from the mold remediation contractors, call 2-3 roofing contractors, and ask them for a quote on the roof replacement cost including decking boards / plywood (ask the roofer to check the attic area), attic ventilation improvement, and insulation if necessary.
Be cautious if they only suggest humidistat controlled power vent installation - without properly functioning soffit vents or any type of vents along the lower portion of the roof this might not be an adequate solution.
If the attic insulation replacement is not required (it most cases it will not be possible to tell without laboratory testing), make sure it's sealed with plastic foil before the roof and its decking replacement. Fold the foil sealing its contents after the contaminated decking has been removed, and dispose of as a regular waste (EPA recommendation).
I personally wouldn't even attempt to do it myself, so my suggestion is:
Use a professional mold remediation company:
- check their background and check it manually by calling their clients
- ask for clients who had their attic mold remediated approximately 1 year ago - it usually takes a winter for the mold to start growing again if the job wasn't fully completed
- Insist on removing the mold completely instead of encapsulating it (Media Blasting methods give the best results).
- Encapsulation is simply a process of covering the mold contaminated surface with paint (paint like product) that contains (or at least some of them do) mold killing chemicals
If your attic mold is properly removed and all of the issues responsible for its growth corrected, which is even more important than mold removing, it will not re-grow / no need for encapsulating.
- Hire a different contractor for mold testing and mold remediation to eliminate conflict of interest.
- Make sure that you perform an independent clearance test after the mold remediation process completion.
- Clearance test is to determine if there are any mold spores remaining in the previously contaminated area
All wood (framing and decking) surfaces should be perfectly clean (like brand new), unless there was some rotting that resulted from leaking roof or extremely humid conditions in the attic - those sections of wood should be either replaced or reinforced from underneath. You don't want anyone to fall through the roof while servicing it or just inspecting.
How to Evaluate the Types and Amount of Insulation
I have just completed an addition to my house. I've heard that blown in insulation is better than batts since covers the joists completely and leaves no open areas. Do you have any do it yourself suggestions?
Yes you are correct. Blown in insulation is better that batts when installed properly as it does seal the attic better.
First you need to measure your attic area that you plan on insulating. Most attics require a value of R-30, R-38 or R-49, depending on your climate and location. Once you know the square footage of your attic you can determine how much insulation you'll need by simple looking on the chart located on the bag of insulation.
Before you get started you will need to determine what materials you will need. Assuming your home has recessed lights, ceiling and bathroom fans and eave vents you will need the following tools and materials:
Loose Fill Insulation
Staple Hammer and Staples
Insulation Blowing Machine (Available at your local rental store)
I've found blowing insulation into the attic is a simple process. Start and the far ends of the attic. Going back and forth make sure its level and smooth. Make sure to get all areas of the attic and don't fill any vents or recessed light areas. Take a tape measure with you and check the levels once in a while. As an example, if your installing an R-38 of fiberglass insulation you would want it to measure 16 inches deep. As you work your way back near the attic access make sure your helper is getting that excess hose out of the way. When you get to about 6 feet from the access hole stop the machine so you can get on the ladder. Once on the ladder finish installing, making sure to bring the level evenly against the dam you previously built.
The final step is to place a piece of batt insulation in the access hole and carefully put the attic hole lid back into place. Now your done! Stay out of that attic as much as possible from this point as loose fill insulation that has been stepped on or crushed looses it's R value.
