How to warm up cold floors in house with crawlspace

Answered
Are there anything suggestions on how to warm up the floors of a house without a basement? I have seen the insulation in the crawl space and it is covered with plastic tarp (there might be a technical name for it). Our kitchen/bathroom floors are freezing where there is no area rug.

    When building our dream home on piers, the contractor didn't think the floors needed insulation...WRONG! We suffered a few winters before searching for a solution. Discovered a local business that uses a spray on fluffy-type insulation...best investment ever! Our floors have warmed up tremendously.

      Hi hope you don't mind me asking do you live in an old house ?

      I've got a 3 /drop under my house that the house as been built on so the cold air generates under the floorboards

      Do you think what you had done would help with my problem

      I seemed to be waiting a lot of energy

      My gas bills are 80 pounds a month

      Please advise thankyou so much

    We heated the floors in the rooms that have tile floors. It is well worth the investment. It keeps those rooms warm enough that we have closed the heat vents. Best of all no more cold toes!

    Please clarify - is there insulation between the floor joists, and there is plastic sheeting on the crawl space floor?

    I have large area rugs through out my home because of this. Living and bedrooms only have the carpet. Keep your slippers close by. But if they could be heated that would be the way to go. The pocket book is always the answer for what you can do.

    My hubby put insulation between the joists and layed heavy plastic on the dirt floor that he glued to the [ cement blocks ] walls to seal the crawl space . Then we had the inside of the outside walls on the main floor insulated with spray insulation he had them do the in side of the outside walls in the crawl space. I live in snow belt in Ontario Canada and I walk around the house in sock feet . How to fix your cold floors depends on how much money you want to spend? You can look up in floor heating on YouTube. But first make sure the plastic is sealed and the insulation is in the right place. Good Luck
  • This doesn't make sense- why is the insulation on the crawlspace floor? The plastic vapor barrier should cover the dirt of the crawlspace and many leave about a foot all the way around for the ground to breathe a bit. There is much debate on this here in the south. The insulation should be between the floor joists to insulate the floor above and insulation fits between the joists snugly and then there are hangers that hold it in place. Last summer a friend of mine had under her house insulated by a professional company cheaper than doing it herself so with that I would call insulation companies and get quotes. I would not mess with insulation because you need to have the proper gear to install it. It will be well worth the few hundred dollars on your heating bill and comfort to do it. Good luck

      @The Garden Frog with C Renee Sorry if I wasn't clear. The insulation is in the joist. Just the vapor barrier on the ground. I've seen on Youtube that there is insulation for the floor but we don't currently have that. Even with the insulation in the floor joist, the floors are really cold.

    FYI We bought a foreclosed home in 2011with a lot of "deferred maintenance." This past fall the crawl space was redone due to 'critters' that had gained access over time. New batt insulation was installed between the floor joists. held in place with twine, and a new .6mil plastic sheeting installed over the ground and coming up about a foot around the perimeter. With proper insulation tucked up under your floor between the floor joists (no gaps, neatly placed, a proper insulation value for your environment/code) cold floors should not be an issue.

    I installed 2" foam insulation panels between my floor joists. Sealed any gaps with Great Stuff spray foam. Then installed fiberglass batt insulation the depth of the joists. Worked on my back in a three foot crawl space for two weekends.
