Home Sizing

Your home's square footage will play a role in the determination of cost for your inspection. As inspectors check for problems with lead, asbestos, black mold, radon and other toxic substances, they will need to make their way through your structure on a room-by-room basis. More space will require a longer visit. The age of your home may also affect the intensity of the inspection as some materials are more common in older residences.

Addressing the Results

While the inspection process is a necessary step before removing toxic materials such as black mold, it may be one of the least expensive aspects of the process if a significant level of such materials is found. Structural work may be required for removing materials that have been damaged by mold. Additionally, it's important to pinpoint the source of such issues. Excessive humidity or water leaks are some factors that can contribute to mold problems in a home, and you may need to solve these problems to prevent a return of the problem.

Air Quality Issues

Toxic materials in your home can affect your indoor air quality as well as structural integrity of the building. It may be helpful to include an air quality specialist in your investigation if you are dealing with problems like allergies or frequent illnesses. The indoor air specialist will consider the issues while keeping your HVAC system in mind, recognizing that the flow of air in your home directs airborne toxins. Resolving problems with toxic materials may include the need to update your home's ventilation so that a good exchange of fresh air can take place. Additionally, your HVAC specialist can evaluate the humidity in your home to determine whether updated equipment or supplemental humidity control systems are required to keep moisture levels in ideal ranges. As with a home inspector, it's important to evaluate the qualifications of your contractor. Your costs for an evaluation may be affected by the intricacy of your HVAC system and the sizing of your home.
