The walls are very important to your home from the framing to the wall coverings.The walls protect your home from the elements. A failure in the wall system can cause problems. Some defects observed at a home inspection at the wall areas interior and exterior. At the exterior there may be areas where there are gaps in the walls that will need to be sealed to keep out moisture. Also areas around any penetrations are common areas that need sealed. Damaged cladding or missing at the exterior cracks in brick veneer or stone some of which may indicate signification foundation movement. Missing weep holes in brick or stone to allow moisture to escape from inside the walls. Vapor barrier missing or installed incorrectly most of the times not visible during a home inspection.Bowed walls, brick ties that have deteriorated leaving the brick veneer loose. I have observed a wall at a home inspection where the whole wall at the side of the home moved. Spalling bricks which is cause by water leaking into a structure in the Houston area. Water may find it's way into the structure through a crack, missing mortar, loose bricks, gaps around penetrations etc. Thermal expansion due to missing control joints or expansion joints required at long brick veneer walls, brick veneer will grow, missing expansion joint sealant. Extensive vegetation growing on walls at exterior.At the interior there may also be cracks in the drywall some of which may just be cosmetic and larger cracks which may indicate foundation movement. Loose drywall tape, stains that may indicate present or previous moisture entering the structure. If moisture is present inside the walls it creates an area where mold and mildew can grow. Remember moisture intrusion is your homes enemy. Moisture intrusions entering into your homes walls can have devastating effects on your home. Your walls may also be missing insulation leaving areas cold or hot.There are many defects that can be present at the walls of your home. This is why you need to have a home inspection of the property to have these defects discovered.
