Envriomental Areas Mold, Radon, Asbestos, Lead, Allergens all can and be a problem in the home. We are certified to inspect sample and inform you on the best course of action to take should these be a concern to you and your property. Pre-Listing Inspection This type of inspection is usually preformed by the seller before a property is listed or announced for sale. The property owner will preform a seller's Inspectionto determine what damage or other problems exist with a property in order to determine the factors such as fair market value, discount values, or any pre-listing expenditure necessary to increase the value and desirability of the property.


Pre-Purchase Inspection This type of inspection is usually preformed after a property has been on the market by a seller but before a potential buyer has taken possession of the property prior to the closing contract. The buyer will usually sign a contingency agreement with the seller prior to ordering this type of inspection. If a property fails to meet the buyers expectations as a result of the inspection, then the sale may fall through. In many cases, a buyer's Inspection will help both the buyer and seller to identify damage or other potential problems that may exist with a property so that both parties can either renegotiate the selling price or the seller's responsibility to repair the property at the seller's expense prior to the final close. Even if the seller has already preformed a seller's Inspection, buyers should still preform their own inspections to prevent "Seller's bias" in any shape or form Warranty Inspection This type of inspection is preformed prior to the expiration of your home warranty. It is used to take advantage of the features and benefits of your home warranty to assure that necessary repairs guaranteed under your your waranty are executed should a damage or problem be discovered. New Construction (Builder) Inspection This type of inspection is usually preformed immediately after your new home has been built and is considered "ready" for occupancy by the builder and appropriate legal authorities ( such as zoning or building code inspector). Periodic Maintenance Inspections This type of inspection is performed every two years to assure the health of your family and the safety of your real estate investment. Periodic Maintenance Inspections are necessary to assure the integrity of your structure in-between storms and droughts, to identify possible indoor pollutants (such as radon, CO, CO2, mold), to check the building's integrity that may be compromised by cracked beams or foundations, to visually inspect for wood destroying insects, and more. Any of these situations can contribute to decrease home value or pose a physical risk to your family if not identified in time. Investigative Inspection This type of inspection is most-often used when a home owner feels that a problem may exist. For example, you may want to engage in an Investigative Inspection after a heavy snow fall, extended rain fall, if you experience an odd smell in your home that cannot be identified, or if you notice unusual pest and insect activity. In many cases, Investigative Inspections can help homeowners to catch problems before they become an expensive or irreversible liability.
