"Linda was excellent! Knowledgeable, great communicator and honest. We were told structural work was needed on our 100+ year home but after a thorough assessment, Linda recommended tuckpointing only!"

"After a year of working with us, Marc designed the perfect home for our family. He spent significant time on site to get to know the space and spoke to us frequently to ensure his design met our hopes and dreams. His final design is visually stunning and maximizes space use in a way that reflects both the history of the home and modern preferences. His expertise in Chicago building code and city offices was instrumental in our project being approved quickly. He reviewed bids with us to ensure we selected a GC who could do the job and had competitive pricing. He regularly met and emailed with the GC and suppliers to address issues as they arose during the job so that all were resolved to our satisfaction. Throughout it all, he was just a nice guy to work with during a process that can be very stressful."

"They were excellent. They quickly made a draft that only needed 3 minor adjustments. The final product was exactly what I needed. They referred me to a structural engineer for review. The whole process took half of the time that they initially estimated. I would definitely use them again."

"Bill was able to come out within 4 days of my initial call. He was punctual and able to quickly identify the cracks as shrinkage and not any structural settling issues. He charges $400 for an inspection and $650 if you want a written report. We were fine with just a verbal since there were no problems. Pricey for 20minutes worth of work, but we're glad for the piece of mind. Everything went smooth."

Structural Engineering questions, answered by experts

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

The primary reason homes have crawl spaces is so the foundation can reach down below the frost line to avoid dangerous soil movement and structural damage when the ground freezes. They’re more popular in colder climates where the ground freezes down to a few feet, and slabs are most popular in warmer areas where there is no frost line. Crawl spaces also provide a space for utility lines to run where they’re at less of a risk of freezing.

No, it’s not legal for unlicensed individuals to conduct structural calculations for buildings or building repairs. Not only do licensing requirements prevent DIYers from tackling this project, but mistakes can also be extremely dangerous and put your property and anyone inside or near it at risk of severe injury or even death. You should always hire a licensed and certified local structural engineer to make structural calculations.

Dormers must be able to bear the load of their own construction and the added window. The style of the dormer, however, will determine where the weight loads onto your home's structure. A gable dormer bears the weight on the side walls whereas a shed dormer bears it on the front walls.

Proper licensing and experience in residential and commercial structural projects.
