"My initial review was somewhat marginal, but now several years later I will say that the reinforcement has been perfect, and they did eventually provide the engineered drawings that were promised shortly after the project completion. Only hitch was with the length of the steel, which they did correct by welding on tabs to each end. Ultimately it was a good job and completed in one day. Would definitely use them again if I needed to reinforce a structure."

"Joe designed a beautiful family room addition to expand our Cape Cod style home. His design integrated the new room beautifully into the existing house and it looks like it was always there.  All of the builders who bid on his design remarked how detailed and complete his plans were. I would use him again without hesitation. A really good architect and a heck of a nice guy.

"Cigano identified a number of important changes to my architectural drawings to strengthen my structure (a car port). The changes recommended and implemented to my plans ensured my Town would issue a building permit. The Town had rejected my initial drawings and required its review and approval by a structural engineer or architect. Cigano really came through and its owner was easy to work with and highly professional. I would highly recommend Cigano."

Structural Engineering questions, answered by experts

Proper licensing and experience in residential and commercial structural projects.

Foundation cracks that are 1/8 inch wide or less, aren’t uneven across the gap, and don’t continue widening over time are usually just normal settling cracks and don’t suggest structural issues. Horizontal cracks and stair-step cracks on foundation walls, any cracks that continue widening, are wider than 1/8 inch, or where one side juts out beyond the other, are often indicative of structural damage.

Yes, a one-story house can have a load-bearing wall. The load-bearing walls in a single-story home are usually the exterior walls. If the house has a basement with exposed walls, the arrangement of the beams can help indicate what walls are load-bearing.

Most lenders and homeowner’s insurance companies don’t mandate a structural engineer’s inspection, so in most cases, it’s not required. However, it’s a good idea to have one done anyway to ensure you know what you’re buying. You can use the report to carry out repairs after closing or even to negotiate the sale price before closing.

The National Association of Home Builders requires repair of any foundation crack of more than one quarter of an inch, although local regulations may vary. In general, any visible crack that is growing in size, allowing water through, or that you have just noticed, is a good reason to call a structural engineer. Cracks can be a sign of a sinking foundation, so an inspection is a good idea for your peace of mind.
