This firm is amazing. They work professionally and quickly, while caring for their clients. Tim did drawings and review for us in an extremely timely manner, and when clarification was needed, he went above and beyond to assist us, even when it was late in the day on a Friday. Thank you so much Tim.

These fine folks came on short notice to advise us about a broom closet wall that was slated to be removed in preparation for a kitchen reno. It turns out that a portion of the wall is structural support . We were able to return to our kitchen designers in time to adjust the design to take this important information into account before we were financially committed to the original design. Kudos to Will from Biddle for a job well done.
