Before we jump into all the “fun” work I’ve been doing in the basement for the last six weeks, let’s do a post to go over our game plan.
Budget is the biggest driver for the project. We have zero money frankly, but as I said in the last post: we feel strongly that we need the space to be useful, otherwise what’s the point. Before the project the basement was full, no exaggeration, of “stuff”. Furniture, half filled boxes, years worth of stuff that had just been moved from house to house. For example, in our old house we had a library filled with books. There’s nothing like that in the new house, so there are just box after box of books. My wife collects board games and we’ve never once had a place to store and display her very extensive collection. I have every car magazine from 1986 to the early 2000’s. Yes, those can be recycled but I’d like to go through them first. Point is we have more crap than most of you combined.
The basement has to stop being a big catch-all.
Okay, back to design and our plans. Here are the main project areas. I’ll go over them in detail in subsequent posts.
When we built the house, you may recall we used Superior Walls for our foundation. The basement walls are prefabricated out of cement and steel, and stand nine feet tall (9′). The walls feature metal stud facings so we can apply drywall directly to the face of them. No need to fir out the walls which saves a lot of time and money. I just need to frame in a few of the corners with drywall nailers. Note, we would also have to frame in for any shelf or cabinet supports ahead of time. Superior walls cannot support a vertical load so don’t go screwing in cabinets into the studs. More info, and to see nailer diagrams, click here.
The foundation walls are insulated to R12.5 from that factory with blue rigid insulation. When we installed them I speculated that we would insulate them with another R-20 worth of insulation, which I think is the maximum if we fill the rest of each cavity with sprayed insulation. Well to keep costs down we did two things 1) only insulated the top 4′ of the exterior walls and 2) went to a depth of 1.5″ (R-10). Why? The top half of the wall has the most exposure to outside temperature changes. Once you get beyond 4-5 feet the earth’s temperature is pretty stagnate, something like a constant 50 degrees or something (I’ll let you look it up). By the way, cost to insulate the top 4′ with 1.5″ of 2 lb. spray insulation (R-10): $2,164. Three inches (R-20) would have been $4,040.
The floors in the basement are cement (over 4″ of rigid foam insulation by the way). Our basement is prone to flooding if the sump pump ever fails, so that drives many of the design decisions we’ve made in regards to our basement project. Long term our plan would be to cover the entire 950 sq. ft. of living space with ceramic or porcelain tile. Short term though we’ll leave it cement. I’ll rent a floor cleaner from Home Depot and clean the cement myself. Not sure if I’ll seal it at this point. I’ll decide when the time comes. We could stain the floor like we did in my studio. That is always an option, in lieu of putting tile down. For now though regular concrete will suffice everywhere, though the bathroom will likely get tile right out of the gate. Cost should just be a few hundred dollars for cleaning and any tile.
There is some debate whether to put in a drywall ceiling or suspended ceiling. Drywall is cleaner and more finished. Suspended ceilings give you access to HVAC, water and electrical. If you think about it, the other floors of the house are covered in drywall with no utility access. So I think drywall is a fine choice. The problem with our ceiling is there are a lot of pipes, ducts and other obstacles that I don’t want to, or can’t, soffit around. We’ll be putting a drop ceiling in all the living areas except the bathroom. Armstrong has a wide selection of ceiling tiles and a lot of inspiration shots on their website. I got a quote for installing a generic Armstrong system: $3,500. I’ll do it myself. Hopefully the material cost will be closer to $1,000-$2,000. We may hold off and do this next year if we can’t afford it.
The yellow areas will likely be drop ceiling.
Interior Wall Framing
Because of the potential for water flooding should the sump pump fail, I was hesitant to use wood framing. If the basement flooded there’s potential for mold to grow in water-logged studs and walls. Regardless always put down pressure treated sole plates, but I didn’t feel like using treated studs. I was curious about metal framing so that’s what I went with. I still used wood for soffits, blocking and ceiling areas. Look for my thoughts on metal framing in a future post. Cost wise we got an estimate for $1,791 to have someone else do the framing. I did it myself, learned a new skill and spent about $750 on materials to partition the basement. By the way, this includes material for desperately needed storage shelves in the storage room.
I don’t do electrical so we’ll have to hire a pro. We’re doing the bare minimum. With the drop ceiling and good access from the storage room we can add-on later. For now it’s all switches, outlets, and ceiling cans. I’d like to swing for 4″ cans but may just default to 6″ to save money. Would like to populate them all with LED bulbs though. Cost estimate for electrical parts and labor is at $4,000. Yikes!
We’ll drywall everything. I may put 12″ of cement board at the bottom of every wall because of the aforementioned water damage potential. Or not. Estimate we got was $3,757. Doing it myself will hopefully save some money. But I don’t have the patience or craftsmanship (or desire) to mud it all so I may have to source that.
$4K electric, $2K insulation, $1K framing, $3K drywall = $10K, then do the ceiling next year or down the road maybe. We’ll see. I just hand over receipts and the wife keeps track and cuts checks.
Stay tuned for future posts on each step of the way. As of this writing I’m wrapping up framing and the insulation is done.
