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.

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.

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!

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

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

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.

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.

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.

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.

Possibly. This is necessary to keep us off an unsafe highway, or a stretch of construction may force us to take some gravel. Return to FAQ index

We hear this one all the time. It ain’t true. There is no statistical difference in the radon levels regardless of the construction type. The single most important criteria in determining the radon concentrations is whether it’s coming up out of the ground underneath your house. It’s really that simple. Radon isn't neighborhood-specific. It can be high at one house and low right next door.

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.

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.

Easy. Just glue (with Heavy Duty Construction Liquid Nails) the floor pan to the floor, cut a hole for the drain in the floor pan, and hook the drain to the sewer system beneath the floor or to the yard area (relief drain concept). See installation instructions for specific directions.

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.

Answer: If you provide us with the following information, we can tell you how much to budget for this kind of a project.
