      Doug in Colorado writes: Hi Patrick,

      I watched your answers to my question about a guest-room zone with my in-slab heat. The answer confirmed what I had been thinking. It is only used a few times during the winter, but when the temp is raised the system runs for hours. The other zones only require occasional heat to maintain temp. As to cost, affordability is one reason I went with this system when building. I used a system from Radiantec in Vermont that was profiled by Scott Gibson in issue 201.

      I let my son and a friend lay the PEX (younger backs!), and with my son’s help the rest of the installation was very straightforward. There is no ductwork because AC is not needed here. If you have experience with plumbing and soldering copper, you can do the install in a day.

      Best temp for guests?  Years ago, I asked my chiropractor about an extra firm mattress. He said it was an excellent choice for a guest room. Sort of the same idea. As always, the podcast is informative and fun, Doug

      Jeremy writes: Hey Patrick & crew,

      These days I spend a lot more time behind a steering wheel than on a job site so I get to listen to all kinds of podcasts. I have a few items in response to your question about what new homes don’t have that old homes had. Here are a few:

      • Squeaky mahogany front porch boards
      • Detailed, real wood millwork
      • A room WITHOUT a screen or smart device—just quiet

      Hope you and the family are well, Jeremy

       

      Listener Feedback 2.5:

       

      Keith writes: In episode 549 the team was talking about old -home features that we miss, don’t miss, or wish homes still featured. As a kid I remember visiting friends with an old home that had a second staircase in the back off the kitchen.  This narrow, windier stair was such a novelty to me at the time. And while I didn’t sneak out as a teenager, I was perpetually hungry. If our home had had a second staircase like that, I would have been able to sneak from my bedroom on the second floor to the kitchen without going past my parents. That would have been cool.

      Carol adds: Steam radiators, frost on windows, sleeping porches.

      Listener Feedback 3:

       

      Dack writes: A couple of thoughts:

      I think Ian pretty much mic-dropped with his explanation of the difference between decks and patios: patios connect to the outside; decks connect to the structure. Choose accordingly.

      One thing that was missed IMO was their longevity. Trex’s max warranty is for 50 years (and I’d love to see how one looks after just 20 years). Mother Nature’s warranty for Carol’s bluestone patio is longer.

      Roger wrote in about conditioning his shop in Little River in southern North Carolina: Greetings Patrick,

      Thanks so much for taking the time to email me back. I have attached a few pics from my past and a few things I am working on.

      C2 Plan is a retirement home in Little River, NC (Myrtle Beach suburb).  It’s a new build on a beautiful wooded lot.

      Kingstree is my retirement home and where my shop buildings are going up as I am typing this. It’s a 70s brick ranch I am gutting, adding a bathroom, rearranging the current bathroom into a master bath, closing in the carport for pantry/laundry/office space, adding a 12-ft. x 50-ft. screened-in double-gabled porch on the back and a gabled porch on the front.  My plans/engineering are finally complete, and I will be picking them up today. I will follow up with digital plans later if interested.

      USCG-Cheyenne
      USCGC-DALLAS
      USCG-ANVIL
      USCG-UTB

      I also added some pics of a few of the ships I was on. I had a pretty varied career including pollution investigation, search and rescue, drug and fisheries enforcement, and Aids to Navigation maintenance and construction. I was a Navigator and Command Chief on the USCGC Dallas, a ship that’s main mission was to conduct counter-drug ops in the southern Caribbean, which provided nonstop action due to our ability to chase over the horizon with our small boat assisted by a helicopter crew that could shoot out the outboards of bad guys. I also served as Executive Petty Officer on USCGC Cheyenne and USCGC Sumac, and was lucky enough to command the USCGC Anvil constructing Aids to Navigation in the low country (FL border to NC border). There have been several other ships (including temporary duty on Navy ships conducting training and counter-drug operations) and several Multi-Mission Stations, where we operated small boats 45 ft. and smaller, conducting search and rescue and law enforcement.

      Again, I owe the FHB podcast and the Pro Talk podcast for giving me the confidence to start this third career, so please pass on my thanks to everyone. I’m certain I will be going back to the well when the work on my ranch house starts in earnest (which better be soon).

      Please don’t feel like you have to read this email on the podcast. Hearing it will likely send me back to grammar camp.

      Question 1: How do I drain a 3rd floor deck?

       

      Steve writes: With Mike Guertin being the authority on decks, I thought I’d take advantage of his expertise and ask if he can think of a better and/or more cost-effective way of draining this 3rd floor covered exterior deck (see below). It’s a new deck yet to be built.

      Steve-deck

      In the image you’ll see this deck space is over an interior space and involves a raised flooring system with a scupper drain that connects to a gutter.

      Is there a better way of drainage? If it helps, a reminder this is a covered space (just 91 sq. ft.), and the new build is to be in an area with 20 in. of rain and 9 in. of snow annually.

      I’m just the lowly to-be homeowner, but your podcast has been a healthy combination of entertainment and information during the process of getting the house designed with my architect. The ceiling integrated headers I previously emailed about (and you were kind enough to discuss on the podcast with Mike) were integrated into the design.

      Question 2: Do I need to remove my existing insulation before I upgrade to foam?

       

      Esther writes: Hi there,

      I am 72 years old, and I have a question about an older home (built 1973) that has 6-in. fiberglass rolled insulation in the attic eaves. If I wanted to have new blown-in foam insulation installed in the attic, do I have to remove the old insulation first? Will there be a vapor barrier problem?

      I thank you for your response.

      Sincerely, Esther

      Question 3: How do I identify the problem causing basement settling?

       

      Frank writes: This maybe a topic that could have many variables but may also help understand how severe an issue could be.

      I am talking to people about basement issues in homes over 10 years old. The floor is settled in some areas (like a corner) up to 4 in. and along the two walls that create the corner they settle 2 in., and 1-2 in. along the other wall.

      The solution is going to be based on the actual cause, which could be the soil was not compacted or there is water running underneath since the home is on a hill. To inspect and then produce the correct solution could cost from $100 to $20,000 or more! This, of course, is something I have encountered.

      Thanks for your consideration, Frank

      Question 4: Can I replace brick fireblocking?

       

      TJ writes: I’m renovating an old three-story balloon-framed house. There are mortared bricks in each stud bay from the foundation up about 6 in. above the floor level installed as fireblocking, and on the second and third floors there are bricks from the let-in ledger up the same 6 in. above the floor level. I’m trying to insulate and air-seal the house as best I can. Can I safely remove the bricks and mortar and fireblock another way? Ideally, I’d like to insulate the walls and not have the bricks preventing me from doing so. I’ve gutted the inside of the building so it’s fairly easy to chip out bricks and mortar.  Thanks, TJ
