Q: Do you agree with the mold removal procedure recommended below? A mold remediator just came to my house to examine mold growth in two locations in my home as shown in the two attached photos. On the IICRC website he is listed as certified in mold remediation. He stated that the S-520 manual states that if the mold growth is in less than a 10’ area, then a full decontamination chamber is not needed. Instead, he stated that all that is required is covering the drywall in the area of the mold with plastic, duct taping the edges, and cutting out the drywall beyond the ductwork. In addition, he would run an air scrubber in the work area and cover nearby supply and return air registers.

Q: I am a residential electrician and am the general of my own home build in central Wisconsin. I am really struggling to make a good interior wall. I have zip R sheathing on the outside. The r sheathing is 1/2” foam on the outside of my walls. This allows for a thermal break on my inside studs and has a r value of 3.3. Now I understand the fact I need a vapor retarder on my inside walls. Any insulator in my area doesn’t understand the difference of barrier and retarder. This is why I need to do my own insulating. I am down to using r19 faced batts with Kraft paper or spray foaming. I feel that if I install the batts with Kraft paper then that acts as my retarder as well. On the other hand if I use spray foam I would need to install a vapor retarder such as majrex or certainteed. The reason I like spray foam is because of the air sealing qualities. Keep in mind I am the general of my build and will be sealing every penetration on the outside as well. I guess I feel that spray foam if properly installed is superior. I’ve been told that if closed cell spray foam is installed then I don’t need to install a vapor retarder before drywall. If I make sure all penetrations are closed correctly that no air is getting to the spray foam In Each cavity then the moisture cannot accumulate in the wall. There is now a spray foam created by natural polymers that is low Voc which is why I am leaning to this but am looking for more input. I have also thought of using rockwool for my insulation but I would then need to install a vapor retarder as well. This leads me to my next question. On my ceiling I would assume I could just use 6 mil plastic as it’s only being used as an air sealer. I will have blown in insulation in my attic. My assumption is since my attic is vented at the aves and ridgecap it does not need a a special vapor retarder to breath. If you could give me your thoughts and concerns you may have and if you have any other ideas for vapor retarders I would appreciate it. Thanks

Q: Planning to renovate a 1920s bungalow in the SF East Bay that will require air sealing, insulation, and bulk water management in addition to plumbing/electrical upgrades. It seems it would be most efficient to add air, water, and thermal control layers to the exterior and make the attic conditioned space vs trying to get into every little nook and cranny at the ceiling level in such a tight space. On the low-pitch roof, a roofer had previously cut back the eaves [rot in exposed rafter tails] to a few inches from the wall and installed gutters so there is little overhang on the main weather-facing side of the house. Goal is to end up with decent overhangs to protect the walls/windows. What is your opinion of using the "monopoly framing" approach in this type of retrofit: cutting back the rafters to the wall, installing continuous control layers from roof to wall, then adding the overhang to the outside of the envelope?

Q: Hi, seeking advice for exterior wall insulation type and install guidelines for a 1,500 SF one story, 80’s ranch, Florida concrete block home. The house has undergone an extensive mold remediation, all exterior walls are exposed to the concrete block and new windows installed. The house was built with Tfoil fiberglass and furring strips underneath. The contractor wants to use polyiso with furring strips on top. Both bathroom showers are on exterior walls. Everything I read says the walls need to be able to breath/dry out due to solar vapor drive. Insulation companies in my area suggest either fiberglass with the foil like the house had, xps, polyiso, or spray foam. Their concern is condensation, not solar vapor drive. I have not found someone that works with mineral wool and it’s so much thicker. I’m not sure how it would be applied unless the walls were built out. I also don’t see install guidelines for block walls that includes everything I need to know around windows, etc so I can check the installers work.

Q: Hey Cheryl, I have a foundation selection question for a new custom single family residence. I live in Houston, TX, so we have clay soils and lots of heat, humidity, and rain. Most homes are slab-on-grade, with few, usually older, homes on pier-and-beam. I'm looking to build a home with as much moisture control as reasonably possible. It seems slab-on-grade homes suffer from moisture infiltration from the soils in contact with the slab, usually along the exterior walls. Homes with pier-and-beam eliminate the moisture infiltration from the soils, but then invite problems from humidity and lack of maintenance due to short crawl space. Homes built with a basement that is properly moisture controlled with AC or dehumidifier seem to be the optimum choice, both eliminating the soil moisture and eliminating the humidity. However, basements are more expensive and are very rare in Houston (I've never seen one, and I've only heard of one from a contractor). And there may be other problems with building a basement in my region that I'm not aware of. Have you seen homes in areas like Houston with basements? Would you recommend a basement in my area? Do you have any comments on the cost-benefit relationship between building a basement vs. slab on grade in my area, in terms of moisture control? Thank you!

Q: That whole area was a fiberglass shower tub from the 70s with the drain in the place that this drain is now. And we took it out, down to the studs. How does he take the nasty material out of the shower through the hall and living room and out the front door? Would that just be taping a pathway with six mil plastic? I feel so ill equipped to do this and yet it's eating our lives up. At age 77 and 79 there is not the same "we can do it" energy as there was a decade or so ago. My question is if this gentleman agrees to take the shower out, and he has no mold information would the bundle you spoke of give me what I would need to be able to pull that off safely?

Q: Thanks to your site I had Lindsey Blake and hope the Mold dog finally do an inspection on my house. The shower that I questioned you about appears to be the main culprit. The remediator's that I'm going to use are not quite the same as other nationally known remediators that I've consulted with. And I like them and going to trust the process. They do not do the whole restoration, they remove whatever mold is right there and when the mold stops they stop the work. So concerning the shower I will find somebody to probably finish taking off the rest of the tile up to the Ceiling And putting a new shower in. Blake the inspector recommended a fiberglass shower. 5 years ago I took out the fiberglass shower Down to the studs and put a tile one with the glass wall etc. in. I know there is a ton of information out there that you've given and I'm so sorry but my current life won't allow me to go through everything. Could you give me a brief synopsis of what kind of things I would need of the newest materials to make a safe shower, whether one piece something or tile . The remediator thinks the problem was probably the shower pan. They did Find stachy there. most likely I will be unable to find someone that has knowledge of a mold proof shower or it's makings. I am most grateful for any assistance you can give me. It feels so wonderful to have a little ray of… Hope that we could have a little peace soon. Thank you and much thanks to your eternally patient staff.

Q: As I plan my new house, it looks like I'll need to put the kitchen sink, one toilet, and one shower on exterior walls. I know you've mentioned that we need to take extra care to reduce the risk of condensation at these locations. Can you remind us of your pointers on how to mitigate the risk?

Q: I'm designing a two-story house with a slab, and my building engineer and another consultant both say that precast concrete walls might be an excellent solution. According to my engineer and consultant, the benefits include: (1) waterproof, well-insulated walls (2) no "wicking" of moisture from below because (a) the type of concrete used is non-wicking (my paraphrase) (b) and the walls rest on a footing of crushed rock (which is drained) (3) economical construction The only obvious downside is that these walls are hard to modify after they're up. I.e., if you want to move a doorway or a window, you're going to pay a lot of money to cut new holes. My engineer and consultant have built with walls from Superior Walls and from Ideal Building Systems.

Q: What are the main HVAC features a person who’s relatively unfamiliar with HVAC systems can look for (in the limited time they have to assess a potential rental) that reduce the chances the rental’s HVAC system is moldy or will cause mold? Including but not limited to: A) do you want to avoid “pan style” return plenums b/c mold is usually in the plenum? What do you want to look for to avoid this? What do you want instead, & how can you tell if the system has it? B) how can you check to see if HVAC equipment is sized correctly for the apartment or house (so it runs long enough to dry out)? C) do you want the system to take make-up air from outside thru an ERV? How can you check if it has this? If you don’t want this, what do you want to check to ensure the HVAC system has instead? D) how can you tell if the furnace has a humidifier, & if it does, does this mean the HVAC system is extremely likely to be moldy (or might the system have low/safe mold levels—even with a humidifier attached)? E) do you need the HVAC to have a drain pan that’s piped to the outside of the building? How can you tell if it is? F) how can you quickly locate the air conditioning and/or humidifier condensate drains & ensure they terminate into a floor drain or pump, & how can you ensure condensate drains are functioning properly? G) how can you quickly locate drip pans for cooling coils & ensure they are draining properly (other than just ensuring there are no signs of overflows)? (Already know about: want solid (not flex) ducts, all ductwork joints should be sealed with heat sensitive silver tape, no HVAC components in non-air conditioned spaces like attics, No evidence of water on floor/wall around furnace.) Thanks Cheryl!

Q: Hello! We have just finished remediation and small particle cleaning and are building back the 70% gutted house. We want to make the small attic space we have a conditioned and unvented. 60-70% of our home is vaulted ceiling with no attic.

Q: Topic: 1920s bungalow in Oakland (Climate zone 3) with a low-pitched roof (3 in 12) finally getting air sealing/insulation. The foundation has to be replaced so the basement/crawl space will become unvented/conditioned/insulated around the perimeter as the HVAC ductwork is down there. In the very short attic, it seems like trying to air seal at the floor level would be very challenging due to quite limited access around the perimeter. What do you think about air sealing/insulating at the roof instead [also to keep the wiring accessible] and adding a vapor diffusion port to replace open vents in the gable ends? [If this is too specific, just let me know.]

Q: Hi Cheryl, My understanding is that good insulation & air sealing are important partly b/c they prevent air that’s the opposite temp from indoor air from entering the building & causing condensation. In a private consult with me, you recommended using an infrared camera in Jan-Mar to determine whether a building is well insulated and air sealed & whether a shower is leaking due to compromised insulation. --Might you be able to show us how to do this? --Once you see an infrared temperature anomaly on a wall or shower wall (or other area), what should you do? Follow up with a surface moisture meter to see if that area is particularly damp, & guess that if it is, it’s likely due to temp differential created condensation? Thanks Cheryl!
