Marell Inspection Services, Inc.

Typical Repair Costs

Marell Inspection Services does not perform or recommend others to perform any repairs or upgrades that we recommend in a property inspection report. We are often asked to provide approximate costs for the repairs and upgrades we describe.

The following costs are intended as "ballpark" estimates for some of the more common reportable conditions we discover in typical San Francisco Bay Area residential buildings. You should not rely upon these figures for negotiating. If you need to know the actual cost of repairs and upgrades, we strongly recommend that you secure at least three separate bids from qualified individuals familiar with this type of work. Bids should always be obtained from licensed contractors. These prices do not include contractor fees, sales tax, or permit fees.
