Even a gravel crawl space will increase the humidity of the air. Remember that a crawl space is just a hole in the ground and water will be attracted to that area. Gravel works well as a cover-up and to hide this condition. Gravel will also add a tremendous amount of dust in your house, especially if you have a forced air heating system.

However, the question should be: "Does my crawl space have higher mold levels than what is found in the outside air?" When checking for mold, 10 minute air samples need to be compared to the same outside, which is considered to be the baseline. A visual inspection is also possible, but not as conclusive.

Sometimes yes, sometimes no. It depends if there is space between ceiling joists. You need at least 24 inches opening between joists for the air cleaner. If you have adequate clearance, an attic crawlspace installation is similar to the drop ceiling scenario. Cut the appropriate sized hole in the ceiling material and finish the edges with the supplied trim. You'll need to use mounting hardware to support the weight of the unit from a suitable part of your building's framework. See similar questions...

Answer: Generally we say 18 inches, however that distance is just a recommendation. The actual height should be enough to allow for routine maintenance of support systems. The appraiser must have access to the crawl space, and enter to the extent of head and shoulders at a minimum. The appraiser must look for evidence of infestation, rot or any other detrimental conditions. Answer: The subject property should not be rejected. See similar questions...

Consider that if a sewer backs up in a dirt or gravel crawl space it is impossible to effectively clean it. Even removal of the gravel or dirt will still leave residual contaminants. Sealing the crawl space with a vapor barrier and laying a 4" concrete slab floor will result in no more sewage! See similar questions...

We consider an ABC concrete floor system a mini basement. Use your crawl spaces for storage as you would a basement. See similar questions...

We recommend three weeks, as there will be some residual water content emitted as the concrete cures. See similar questions...

Yes. The crawl space beneath a house is another place where ventilation is important. The crawl space can evaporate gallons of water each day. When you seal the crawl space, that water penetrates the floor above and causes more humidity problems in the home. Providing foundation vents in the crawl space reduces the humidity, and a vapor barrier (like polyethylene film) on the ground prevents moisture leakage into the house above. Be sure that attic or crawl spaces are properly ventilated. See similar questions...

To ensure a dry floor, the following must be done. . . preliminary waterproofing, (such as perimeter drain site, sump pump or foundation crack injection), and installation of a plastic vapor barrier between the ground and concrete. See similar questions...

There are many possibilities, some of which include windows, doors, heat registers directly above the crawl space, and even dryer vent openings. Crawlspaces adjacent to the garage can be accessed by cutting a clean hole at step height through the sill and directly into the crawl space. See similar questions...

You enter through a large tube connected to the planetarium. Most kids love to crawl in, but anyone can enter by merely bending over and walking through the entrance tunnel. See similar questions...

Mold growth in the crawl space is less likely to affect the interior of the home that mold growing inside the living area of your home. However, pressurization caused by airflow into and out of the vents, or through the introduction of air via the HVAC system could cause the transfer of mold into the home. The important thing in the crawl space is to correct the issues causing mold to grow. See similar questions...

SteamMaster will pump out standing water and begin drying your crawlspace with air movers and dehumidifiers which will help to prevent the growth of mold and mildew. See similar questions...

Yes, although care must be taken to ensure the Desert Spring Humidifier is not subjected to freezing as this will damage the unit and may cause leaks. Units located above a ceiling should also include the installation of the overflow line. You can reduce the risk of freezing by carefully insulating the incoming water line, 6 inch flex duct, and humidifier unit itself with fiberglass insulation (be sure not to put insulation directly against the motor).

Basement-foundation plans are included with all houses. However, we dimension the foundations in such a way that they can still be used with slab or crawl spaces with very minor changes for your contractor, or slab and crawl-space foundation plans may be added to blueprint and mylar orders for an additional $50.

If the crawl space is vented to outdoors, leave the door closed. If the crawl space is NOT vented to outdoors, it doesn't matter whether the door is left open or closed. The more important answer is that the smart way to design and build a crawl space is as intentionally conditioned space. Then it makes no difference how the basement / crawl space door is managed. See the response to another FAQ about crawl spaces for more information. See similar questions...

If you are a headache sufferer, your obvious concern is to obtain safe, dependable relief. You should avoid making things worse by using drugs, even over-the-counter nonprescription drugs that can have serious side effects and dangerous interactions with other medications or supplements you take. You should also be aware that many people experience what are termed "analgesic rebound headaches" from taking painkillers every day, or nearly every day. See similar questions...

The house was built like this because building codes allow exposed crawls. It would have been a substantial savings for the builder at the time. The building codes are from the 40s and very little thought or effort has been put into the crawl space dilemma. Our firm is working with researchers and other professionals to rectify the oversight.
