Building or construction defects come in all sizes and shapes. Some types of defects are plain and obvious. Others might be hidden behind walls or under floors. Any of the following conditions may indicate a problem in the design or construction of your home or building:
Water leaking through windows: Water leaking through windows is a common problem, and often relates to the window "flashing" that is placed around a window during construction. Window flashing is what keeps rain or other water from entering the wall cavity or from coming into the building. Flashing around windows can be difficult to install. Window leaks are common problems in any type of wood frame structure. Staining or moisture at the baseboard below a window is a common indication of a defectively installed window.
Soils subsidence or soil expansion: Before a home or building is constructed, a building pad is often created. Frequently, homes and buildings are constructed on top of fill soil, which means that soil brought to the site during construction so that a building pad can be created. Some projects are built on deep fill, such as when a canyon or ravine is filled with soil to create a level building pad. In other cases, the amount of fill below a building might be only two or three feet. In either case, this soil may settle or subside, or expand or swell. When the soil settles or expands, the building on top may settle or expand, causing the building, driveways, or walls to crack or slope. In severe cases, building movement due to soil settlement or expansion might cause doors or windows to become wracked, and difficult to open or close. Concrete building slabs can become cracked and separated.
Roof leaks: Roof tile or shingles are required to be placed precisely so that little or no water actually comes in contact with the underlayment below the shingles or tile. Penetrations through the roof, such as vent pipes, need to be flashed to prevent water from entering into the building structure. Roof leaks are not normal and typically are caused by poor workmanship.
Cracking Stucco or Drywall: A minor amount of cracking in stucco or drywall might be acceptable, particularly around corners at doors and windows. However, significant cracking in the field of a wall can be an indication of a more significant underlying problem, such as a problem with the structural framing, or a problem related to soils movement.
Mold: Mold are micro organisms that are a natural part of our environment. However mold that is growing behind walls or under floors may be toxic, causing damage not only to the building but to the health of people who live or work there. Mold needs two things to thrive: food ( typically wood) and moisture. A defect that allows water to enter into the wall cavity behind drywall can often result in a mold problem. Mold conditions need to be examined by professionals to determine if the type of mold present creates a harmful environment. Common problems associated with mold include severe allergies, asthma, or related symptoms.
The above categories represent some of the more common construction or design defects, but are not meant to be an exhaustive list. Other common problems include leaking retaining walls, delaminating and leaking balcony decks, leaks below tubs or showers, and leaking into below grade garages.

Its an easy job to repair the plain defects but its hard to repair the obvious defects. Liquid EPDM is best solution to all of the defects even they are plain or obvious since it can acquire any shape due to a liquid.
