crawlspace

  1. Building & Construction
    Hi has anyone dealt with a crawlspace like this? The ground is very uneven, covered with boulders and a lot of support columns. House was built in 1850. The ground is very damp as you can see. I've put a 70 pint dehumidifier since this photo was taken and it really helps keeping the humidity...

    Hi Folks, We have a new house under construction right now and curious what the standards are for finishing out the crawl space. I'm familiar with rocks and vapor barrier since a couple of houses we've lived in had that. But during the build of this current house it's just dirt and the house is...

    I’m having an electrician install a GFCI outlet in our crawl space. What materials will I need? GFCI outlet, metal box, anything else? I’m assuming they will have some screws and wiring for the job. If not, I’ll contact them to make sure.

    For a drain line, there is a 12" minimum burial depth in earth (when not under concrete). That's from the dirt-level, to the top of the drain. My questions: 1. Does the minimum burial depth apply when buried under a floating pier-and-beam home? (aka: an open, dirt crawlspace) 2. Alternatively...

    Hi, I just partially encapsulated my crawl space (10" vapor barrier around the perimeter). I have a ventilation fan in one of the vents installed. I was thinking what should be the other vents positions (open or closed) during each season: spring, summer, fall & winter? I live near Raleigh...

    HI, House was built in 1992. We bought it 2 years ago. Discovered mold in the crawl space. Last year we - remediated mold with RMR 86; foam spray insulated the exterior walls; sealed off open vents; added a large dehumidifier (Damp2Dry) The problem is the crawl space now has a musty...

    Hi, I get water in my crawlspace and I found the issue is the slope/grading of my flowerbed. I learned that the slope should be 4" to 12" (please correct me if I am wrong), or around 18 degrees angle. We should the soil be touching the wall? at the footing, below, or above it? Any help would...
  8. Insulation
    Hello, I am seeking advice regarding how to best insulate an addition over a crawl space. A planned flooring renovation has led to the floor deck above a small crawl space to be removed and I need to seal it up again. The room: 13'x19' Dimensions. Crawl does not have enough space to get under...

    Good evening! Anyone here have a Santa Fe Compact or similar in a ducted installation? I have a 26 x 60 crawlspace with the dehumidifier located at the lowest corner, near the sump pit and access door. The far opposite corner tends to have the highest humidity, but the dehumidifier doesn't...

    I need to tap into the existing natural gas line under my house in the crawlspace to power a tankless water heater. The problem, of course, is I have a fireplace and a range that are downstream from the point at which I need to tap in. It's impractical to unscrew every single fitting after the...

    My water heater has its pressure release valve routed into the crawlspace. I was flushing it and had to open the valve to get it to fill. It got too full, and started releasing cold water into the crawlspace. There's a small puddle under there now. Should I be worried about this? Is there...
  12. Roofing/Siding
    After an extensive Google search and visiting 3 different stores (Lowe's, Home Depot, Menards) I can not find a siding vent that fits a hole that is 9.5 x 5.5 inches. Does anyone know where to find one? Thanks!
  13. Electrical
    I want to keep my crawl space dry without spending a fortune on electricity from dehumidifier. Right now I switch between fan and dehumidifier depending on season. I live in northeast. I had heavy rains this spring sump dump stopped working and my dehumidifier got flooded. Now I'm in the market...
  14. Building & Construction
    So I'm remodeling my laundry room (a small room in between our kitchen and back porch). I'm trying to figure out the best way to cover the sides of the crawlspace so that the pipes don't freeze and rodents stay out. There is no concrete footing all around it. It sits on concrete pillars...
  15. Remodeling
    Planning to begin the process of finishing my basement, and I am unsure what I need to do with conditioned crawl spaces. Home was built in 2015 and the basement has 2 crawl spaces that are fully encapsulated and insulated (ceilings not insulated). I would like to put walls over these areas with...

    I'm in the middle of renovating a small (225 sq. ft) 3-season room up here at my home on Cape Cod. New windows, insulation, drywall, flooring... the works. Hoping it will eventually become a year-round room. Well, underneath this room is a 2-3' high crawlspace, where the rest of the house is a...

    Hi there, I'm new to this.. am having my crawlspace encapsulated and dehu installed. Contractors said they would treat 'mold exposed' areas with antimicrobial and then water seal all wood. They said they would use materials/treatments of my choice. I thought I'd ask here.. I'm thinking...

    One section of my home is not over the basement. Its around 25L x 14W. the crawl space is huge is full basement height inside. Its on a slop so the front end is about 5 feet under the grade and the back end about 3. It currently has one small vent, plastic down on the ground, and R-19 Faced with...

    I want to replace some of the deteriorating fiberglass insulation in my crawlspace, but it has no joists between the pier & posts, so the gaps between the beams are nearly 4 feet. The photo in the link shows the same type of construction. The photo in the link is not my crawl, but shows how...

    I currently have a slab on grade ranch home in Ohio. I would like to add 16'x20' addition. I am trying to figure out if I can build a crawlspace for the addition without raising the finished floor height from the house to the addition. I would prefer to not use a slab foundation for the addition.
