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.

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.

We can treat just the attic or just the crawlspace. Our process is much more effective at decontaminating these areas than other old-fashioned methods.

Seal up the largest air leaks in your house--the ones that whistle on windy days, or feel drafty. The worst culprits are usually not windows and doors, but utility cut-throughs for pipes ("plumping penetrations"), gaps around chimneys and recessed lights in insulated ceilings, and unfinished spaces behind cupboards and closets. Better yet, hire an energy auditor with a blower door to point out where the worst cracks are.

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.

You know you have mold when you smell the "musty" odor or see small black or white specks along your damp bathroom or basement walls. Some mold is hidden growing behind wall coverings or ceiling tiles. Even dry, dead mold can cause health problems, so always take precautions when you suspect mold. Mold is often found in areas where water has damaged building materials and furniture from flooding or plumbing leaks.

Back to TopMold stains objects or areas such as walls and ceilings and has a musty, earthy smell. Mold can be hidden behind furniture, under carpets and floors, under cabinets, in closets or attics, and inside walls.

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.

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.

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.

It is recommended that you contact your local health department. Also, there is an informative web link on the Broward County Health Department's web page.

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.
