"I reached out to Roman for a professional structural evaluation of my home after receiving several alarming quotes from foundation companies. Roman was extremely thorough and reviewed all areas of concern in the home. Ultimately, he told me that repairs that were quoted at $25-$30,000 were not necessary whatsoever. Thank you Roman for saving us from a significant unnecessary expense. We are very grateful for your help!"

FAQs for engineer structural projects in Downers Grove, IL

To determine if a wall is load-bearing, start by checking your home’s original plans or asking a structural engineer. Exterior walls always carry weight, but interior ones only do if they sit over a beam or run perpendicular to floor joists. If a wall lines up with posts in the basement or falls directly under the roof ridge, assume it’s load-bearing and call a professional before attempting to remove it with a sledgehammer.

Calculating the wall load and sizing the beam must be performed by experts to ensure structural safety. You need a structural engineer to evaluate all load aspects and determine the proper beam dimensions. A professional engineer performs precise calculations and advises on any necessary enhancements, such as larger footings for support. An inspector then verifies that the revised structure meets all safety and code regulations before the finishing work begins.

Hiring a structural engineer is essential for ensuring your home remains structurally sound during any major renovation. Their responsibility is to deliver expert assessments and design recommendations for load-bearing modifications. The average cost to hire a structural engineer is $500, with rates ranging from $350 to $800. Consulting a licensed, experienced engineer guarantees that every structural project, whether constructing a new home or remodeling an existing one, is completed safely and efficiently.

Almost all load-bearing wall removals require a permit as they support everything above it, and building departments want proof that the new beam can handle the weight. Pulling a permit triggers plan review and inspections that confirm the work meets local code and safety standards. Skipping this step can lead to fines or being forced to rebuild later, so have your contractor pull the permit before work starts.

Removing a load-bearing wall to create an entrance for a carport or covered patio is a task that comes with defined cost implications. This modification requires extra structural adjustments to ensure safety and proper integration with the adjoining space. When you convert a wall into an entryway, you can expect to pay between $3,200 and $9,500, with an average cost of $6,400. The additional work required for this conversion reinforces the home’s integrity and ensures compliance with applicable building codes.
