Even if you brought the footings up, that's still ground contact. Concrete sucks up moisture from its surroundings, and that moisture is held in place next to whatever's touching it, which is why you want some means to prevent rot in the wood touching it.

That product uses cedar lumber, which is rot-resistant but not immune. You could install it as-is with the expectation that the posts would need to be replaced eventually; how long they last depends on your climate. Or you could see about replacing part or all of the posts with treated lumber. I think that as long as you have, like, an inch or two of treated wood above the ground, the rest can be untreated. It's mostly a matter of making sure that excess moisture can drain and the wood has a chance to dry out from time to time.

I live in Socal so its dry most of the time, but I've seen in wetter climates pressure treated wood that's begun to deteriorate in only a few years with direct concrete contact - not even buried. Aren't you supposed to have some kind of metal piece in between the concrete and the post for ultimate protection?

Are there any good statistics or testing for how long cedar lasts versus pressure treated?

It's my understanding from stories of old men on the internet that unless its old growth heartwood cedar of lore, hand hewn and rough sawn by burly men with even burlier beards, then it's just as worthless as low grade pine studs from Home Depot.

Let the liquor do the thinkin'
Recently moved into a new house and finally hung my string lights up over my patio area. The house I was in previously (renting) had a large deck, and I just hung these around the perimeter of the deck railing and ran outdoor extension cords over the sliding door and along the bottom of the deck and they basically stayed outside year round for the last 3 years. I just plugged them in at night and unplugged them before I went to sleep.

In my new house I actually have them as they’re typically used, off the ground over top of the patio. I also ended up getting an outdoor WiFi outlet so I can just turn them on and off using my phone. Wanted to see if anyone could recommend the best way to supply power to these.

The lights are around 8 feet off the ground and to get them even over the patio, the plug at the start of the lights is about 2.5 ft away from the house. I have an outdoor outlet, and the first thing that I know that I need to do is replace the cover with an “in use” cover that I’m going to pick up today. The outlet is at ground level and I need to get power to the lights 8ft up. In the picture you can see I temporarily have an extension cord plugged in just to make sure they were working after I got them all set up, but I obviously don’t want a cord hanging there.
I think the two main options are 1) install an outdoor outlet up higher on the wall or 2) run a heavy duty extension cord up the wall to the right of the windows and secure it with staples or in some kind of conduit.

There is an outlet in the kitchen, on the other side of the wall below the upper windows, so I could come off that to install an outlet on the outside of the house. I’m not really inclined to do this because it will look a little crazy to have an outlet right in the middle of the house, and even with the outlet there the plug on the string lights is still away from the house so it wouldn’t reach. Also we plan to re-do this patio in a couple years and at that time I would probably try to build in lighting or more electrical and not need an outlet there.

The easiest thing to do is to run a heavy duty 12 gauge extension cord up the wall. Regular cable staples are not working, they just won’t go into the mortar and the nail just pops right out and bends. Ideally I could run it through a conduit or raceway, but having trouble finding what would be the best to use to attach to a brick wall. I had used some in my house that are the regular plastic ones with an adhesive back, but I’m not sure that would stick to brick and stay there. Having it enclosed would help protect it from rain, and I can also get waterproof covers for the plug connections and will be using an in-use outlet cover.

I know the real answer is you can't use extension cords for permanent power supply, but is there no other option than installing a new outlet and moving the lights closer to the wall?

Any other suggestions for how to get this plugged in safely and without looking too bad?

Now I have very little say in how he fixes this, but I’m curious because I’d like to own my own place someday, and I also want to judge the quality of work this guy does. I’m guessing window replacement can be a pretty difficult/technical and expensive project, especially retrofitting? Is it ever okay to just cover up exposed wood and caulk around the edges like this as a permanent fix? My instincts are telling me that water will find a way to seep in no matter what, and sealing the wood with cladding will prevent evaporation of said water, and it will just continue to rot. The wall will sponge up any leaks and the only benefit will be that water won’t stream inside the building.

I just had my windows replaced - they were done from the inside, and the old wooden exterior was covered in aluminum flashing like you've pictured there. As far as I'm aware, that's the standard for replacement windows unless you want to get into a massive rennovation.

That's... strange. That is in fact aluminum wiring. That was installed from the late 1960s to the mid 1970s when aluminum was cheaper than copper, before everyone realized it was a bad idea and went back to copper. However, that's a tamper resistant outlet. Those became standard in 2006, so that definitely isn't an original outlet. However, the ground wire is looped around the ground screw in the wrong direction, so it wasn't a pro who swapped it out.

You have a problem. To replace that outlet, you'd need an outlet that is both tamper resistant and CO/ALR rated. I've never found one rated for both. Furthermore, since this is a kitchen countertop outlet, it has to be GFCI protected. I've never found a CO/ALR rated GFCI either, but they do make tamper resistant GFCIs. Your best bet is Alumiconns. They're purple colored, insulated terminal blocks that are rated for joining aluminum wires to copper wires. Join your aluminum box wiring to a short length of copper, wire the copper to your devices. Match the copper wire gauge to your circuit. If this is a kitchen countertop, then it should be 20 amps and 20A circuits require at least 12 gauge copper. IIRC, aluminum was always 2 gauges wider for the same amperage, so 10 gauge for 20 amps?? The only problem is that to properly install Alumiconns, you need a torque screwdriver. They're a little pricey.

edit: GFCIs can protect other devices down branch. Since this box has only one cable run in it, it's located at the end of the branch. You might have a GFCI outlet elsewhere up branch from that box. But again, there are no CO/ALR rated GFCIs. You would need to fix the wiring in that box too. Or there could be a GFCI breaker. Who knows. GFCI breakers are rare since they cost 3-4x what a GFCI outlet does.

I'm guessing someone popped a random new outlet in at some point for whatever reason, the whole house is full of insane decisions. Why does a new one have to be tamper resistant? No GCFIs around except for in each bathroom. Don't light switches and light fixtures and appliance hookups need to be inspected and possibly adapted as well?

Fun fact, this was where the microwave and toaster oven were plugged in! Also my landlord is ignoring me.

This might be a really dumb question: I’m building a simple platform with some 2x6s and a framing gun outside this weekend, are there any good tools to make sure the corners are square when I nail them in.

Right now I was just thinking of rough cutting all the pieces, including 2-3 internal boards for support, and then the structure should move too much. But I was curious if any of the existing corner clamps work or if I should try ratchet strapping the whole perimeter of it.

Probably definitely overthinking this.

How big a platform?

Do you have a speed square?

When I was building my garage & doing wall framing, I laid out the sill plate, nailed in the studs at each end, positioned the top plate, checked the corners with the speed square, and popped nails in.

Then I'd temporarily nail or screw in a brace at an angle across the plate and the end stud, them install the rest of my studs, checking each one with the square as I went.

It may help to pair up the two 2x6s that act as the long-axis perimeter, and strike off marks at 16" across both, and nail your joists to those marks...checking square as you go.

The standard trick for ensuring squareness is to measure the diagonals. If opposite edges are the same length and the diagonals are equal then the rectangle must be square; there's no other option.

Well, if the original outlet was installed 50 years ago, it may have just worn out and the slots wouldn't hold onto plug prongs anymore. That happens to plugs that are used a lot, like kitchen countertops. Some electricians install spec/commerical grade outlets for kitchen countertop outlets for this reason.

Tamper resistant outlets must be installed in all living spaces. They prevent kids from sticking metal things in outlets and getting shocked. It's the better alternative to those plastic babyproofing outlet inserts because you don't have to pry out the plastic first to stick a plug in.

Yes, you'll need to inspect those light switches and fixtures and appliances. Aluminum is still used today on occasion for big appliance circuits, like electric ovens and ranges. They're 50 amps.

That's probably why that outlet go so melted. Microwaves pull a lot of juice.

We're looking at finishing part of our basement. I'm fairly stupid, so I'm struggling with what all I need to do.

Here's the insulation there now:





My (completely new to this) thinking is that I'd want to remove the blanket-style stuff and adhere rigid foam board to the walls, then frame the stud walls right up against the foam board, right?

Our plan is also to leave the ceiling exposed and just paint it all white (masking off what shouldn't get paint on it) to maximize headroom and keep access to wiring, ducts, and pipes. I'm trying to think of the best way to cover the rim joist cavities. Can I just put a piece of rigid foam board in front of the batting there, and then cut drywall to extend to the subfloor? Do I need anything in between the sill plate and the drywall?

I'd contract out the drywall finishing because gently caress that, but before that I have a friend to help me install outlets. No room or desire for a bathroom or wet bar down there, so no plumbing.

One other question is radon — I know we have a mitigation system, and it's in an area of the basement that'll remain unfinished and behind a door. Is that going to be an issue in the habitable area? Or will the finishings serve as a mitigation in that part?

I need to cut off slighty under flush 6 x 10mm stainless diameter threaded steel rods that are epoxied (chemical anchor) into a concrete block wall. They were previously used to secure a gunsafe which has now been removed, but I'm left with the rods sticking out.

The wall is concrete block with plaster board (sheetrock) ontop - so the 'below flush' would just be a little bit into the board rather than the concrete block. I just need enough to use a filler so I can sand it smooth and paint the wall.

I'm guessing my options are - dremel with a few decent metal cutting disks, a proper angle grinder, or a multi-tool with a carbide tipped blade.

I don't have any of them so its also which would be useful for any subsequent diy stuff as well. I'm leaning towards the dremel, but an oscillating multi-tool sounds decent but I've no idea if they could literally cut it.

My intuition is that the dremel has the broadest potential applications out of those tools, assuming you don't have hobbies/work that call for an angle grinder or OMT. I'd order them as dremel > OMT > angle grinder.

That said, your best bet here is to cut out the drywall around the rods, cut the rods down as close as you can to the concrete blocks, then patch the drywall. I don't see how you could cut something under-flush. Indeed, even with cutting out the drywall, when you patch it you're probably going to need to remove some material from the back of the drywall patch, as the rods will still be a bit proud of the concrete block and might deform the front of the patch when you install it.

An angle grinder could absolutely grind down into the concrete block a little bit to leave them under-flush. An oscillating multi-tool might work, but you'd go through a bunch of blades. A sawzall would work if you could come at it from the side, the blades flex a little bit. Personally I think an angle grinder or sawzall would be the easiest, it's like a 5 minute job, max, with either of those. I wouldn't even try with an OMT, and a dremel will work but it'll take maybe 30 minutes and you'll shatter a bunch of the cutting disks if you're not careful.

I already own all of those tools, and have used all of them for cutting metal in various places many times. If I didn't own any of them and had to pick one, I agree the dremel is a pretty handy thing to have and probably sees the most use out of those for general random hacky fixes.

My sawzall gets the most use out of my sawzall, dremel, and angle grinder. I use it for anything that needs sawing.

That said, Home Depot will rent you an angle grinder for $20 per day if you don't want to commit to anything. And Harbor Freight will sell you one that will work good enough for $15-20.

It's easy to mess up the wall assembly in basements. You have, luckily, picked one of the few assemblies that works. There are two areas where you may still get tripped up: (1) make sure you install foam of the right thickness; and (2) make sure you install the foam sheets tight to each other (caulk if you can) to prevent air migrating around the sheets. Your goals are: keep the dew point temperature inside your insulation, prevent the concrete from becoming a condensation surface by keeping the foam tight to the concrete, and prevent moisture-laden air from reaching the concrete in the first place.

The thickness of the foam depends on your climate zone and your building code. If your locality follows IRC 2015, the most commonly accepted code in the united states in the year 2020, it's R-5 for zone 3, R-10 for zone 4, and R-15 for zones 4 marine, 5, 6, 7, 8. The 2015 IRC does allow for cavity wall insulation in basements, I bring this up because you might see if you go poking around. This is a code legal, but riskier assembly compared to spray or rigid foam. If you're thinking about using batts, please reach out so I can dissuade you.

Your radon system may depressurize the fill under the slab, so it 'works' no matter how you finish the space as long as you keep the system running. If you have a system that doesn't depressurize the slab and instead just exhausts the interior basement air, I'm not sure and you'll need to ask an expert.

All the instances I've heard or read about angle grinder accidents involve breaking one or both of the 2 cardinal rules:

- Always keep the guard attached, and keep any parts of your body behind it (i.e. if you can see the disc in use from an angle tangential to the disc, it can hurt you)
- Always use the side handle (i.e. keep two hands controlling the grinder at all times)

A Honey Badger doesn't kill you to eat you, it tears off... your testicles.

So I just moved into a new place. I switched the utility accounts to my name, and while I was moving in, I realized I have no hot water. I went down to the basement and the pilot light on my water heater had gone out. I reset it without any hiccups and reset it to the temp that it was set to before. It’s a gas water heater with an electronic gas valve that’s upwards of 10 years old. Ever since then, the water is just not coming out that hot. I’ve incrementally increased the temp setting, and while it’s gotten better and feels warmer, I’ve maxed the setting and it’s still not that hot. Depending on which sink/shower I try, some feel hotter than others. Especially when I go to the second floor bathroom, it doesn’t feel very warm.

I contacted the previous resident(who I trust not to be gas lighting me) and they said they had no issues with hot water. So I’m wondering if something could’ve happened when the accounts got switched and the company came to mess with the tanks? Especially since I had to reset the pilot while moving in, the timing seems very odd and makes me think that it’s a tank issue. Is that something anyone has experienced?

I don’t hear any weird noises or smell anything strange coming from the water heater, if that means anything to anyone.


Tonight when I get home, I’m gonna try draining the tank and seeing if sediment build up is the issue. I just wanted to crowd source any other possible explanations that I should explore before resorting to calling a professional.

If you have the same gas supplier all they should have done was come by and fill the tank. That tells them how much gas was left when the last guy moved out so they know how much to credit him.

If they had to swap out the tanks for some reason they would have needed to come inside and bleed out any air that got in the lines during the process.

Same supplier and everything. No change in tanks. But they did have somebody come out and check out the tanks before they had anybody refill it. I only saw them when I was heading to work, so I didn’t stop and talk the the guy. That was before I was moved in and noticed any issues with the hot water heater. I just didn’t know if there’s anything I should check on the tanks themselves besides that they’re full and the valve is open.

Alternately, have you turned it off and drained the tank? I know the PO said it was fine......but maintenance is required on these things. It could have a ton of sediment in the bottom making things not work. But I'd be looking at the burner first.

My dad's going to be getting a wheelchair probably sometime in the next 3-6 months. I've been asked to build ramps for the house so it's wheelchair accessible. There's already a chair lift to handle the staircase inside.

I know there's requirements for things like slope and handrails, but I don't know what those requirements are. Is this part of the local building code or is there a general resource I can rely on?

All of the spots that will need ramps are on either concrete or mortared stone patios. I'd prefer to limit the amount of damage done to those surfaces during installation, though obviously the ramps will need to be secure and the handrails need to not be wobbly. Similar question: can anyone recommend resources for how to design and build good-quality ramps?

As a final note, it's not a hard requirement that I do this; if this is a "hire a professional" kind of job then that's absolutely an option. But I'd rather do it myself if possible.

Your radon system may depressurize the fill under the slab, so it 'works' no matter how you finish the space as long as you keep the system running. If you have a system that doesn't depressurize the slab and instead just exhausts the interior basement air, I'm not sure and you'll need to ask an expert.

I'm zone 5a, so it sounds like I'd need the big 3" foam boards.

How does this work with the staircase? The staircase is right up against the concrete, so adding the 7-8" of insulation->framed wall->drywall would be... incompatible.

I'm thinking I'll call a contractor and ask if I can pay to have them consult and tell me what I'd need to do, then either have them do the parts I don't feel competent doing or do it all.

My dad's going to be getting a wheelchair probably sometime in the next 3-6 months. I've been asked to build ramps for the house so it's wheelchair accessible. There's already a chair lift to handle the staircase inside.

I know there's requirements for things like slope and handrails, but I don't know what those requirements are. Is this part of the local building code or is there a general resource I can rely on?

Take a look at the ADA codes - there’s probably something there as a general concept. https://www.ada.gov/2010ADAstandards_index.htm

STRIKE!
Is it safe to have a home gym on a second floor?

Deadlifting and squatting can be a few hundred pounds, which could be a lot of force if dropped.

Obviously the goal is to never drop it... and would have a rack / bumpers / platform.

I've been to gyms where the equipment was on second (and up floors) but that was obviously in commercial spaces.

America has a lot of obese people and it's not like they fall through upper floors.
