This Deep Wood Rot was caused by bad flashing

Most often the fix of the cause is simple, but the damage in many cases requires a level of surgical precision, that can only come from an extremely high level of expertise. Especially in major wood rot structural repair, as well as recreating architectural components to match existing, say in Historic wood rot restorations.

From modern to vintage homes we have performed rot restorations by first inspecting and making a determination of the causes, the extent of the damage, and provide the best course of action to take to ensure your home is fixed for good. Although, in most cases, it is almost impossible to provide an exact cost, we do provide a preliminary estimate so we have a budgetary number to work from right from the start. We then proceed with a time and material method, and record everything in a system that we have developed called the daily log. With a high level of personal communication and a recording of the daily actions and materials, the daily log becomes your invoice. This method provides you with full disclosure of activities and ensures you know the problem is fixed for good!
