"I've worked with Donnie on several properties to evaluate structural issues, he's always been very professional and thorough with his inspections and identification of structural issues. Recently I had him perform a structural repair on one of my properties that had a tight deadline due to insurance and he got it done without an issue. I would recommend Donnie and Upstate Structural Repair for any structural repairs or consultation!"

"We were initially overwhelmed with the renovation and addition possibilities of our fixer upper. However, Dan's vision, timeliness and easy manner made our experience a very positive one. He offered suggestions which improved the design and saved costs. We wholeheartedly recommend A+ Drafting Services!"

"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."

"Tommy Hood saved us thousands of dollars with our foundation repair. Others quoted from $8,000 to upwards of $80,000. He fixed it for much less and explained why the other estimated work was not needed. Tommy was honest, dependable and on time. I would consult him before I ever had anything else done on my home regarding structural work."

"We thought we had foundation problems and contacted CNT for an estimate on repairs. ED VanOsdol came out at the specified
time to give us a quote. Ed generated a computerized lay out of the structure of the house and then crawed under the house and made pictures of the structure. He indentified one problem area which was minor and a potential problem area. He explained
what was happening to the foundation and because it was so minor, he told me how I could fix it myself. I told him that I would
pay for the inspection, but he said it was not necessary. If I ever do have problems with my foundation, I will certainly use them
for the repairs. I would recomend CNT to everyone. They are very professional and honest.

Structural Engineering questions, answered by experts

In Seneca, document any cracks, uneven floors, or moisture spots with clear photos and notes. Clear gutters and direct water away from your foundation to prevent further issues. Avoid attempting repairs on load-bearing walls or foundation elements yourself. If you notice sudden changes, such as widening cracks or doors sticking, contact a structural engineer for a professional assessment before problems escalate.

Helpful?

After completing structural engineering projects in Seneca, keep all signed engineering reports, updated property surveys, and inspection records. Retain permits, warranty documents, and material certifications, especially for foundation work or structural repairs. Store before-and-after photos and any correspondence with your contractor. These records will help with future renovations, insurance claims, and resale, ensuring your investment is well-documented and protected.

Helpful?

In Seneca, structural engineering projects provide immediate benefits like improved safety, better structural integrity, and enhanced property value. Over time, you’ll notice reduced maintenance needs, greater energy efficiency, and more flexibility for future remodeling. These upgrades also extend your home’s lifespan and boost resale appeal, especially for properties near Lake Keowee or those catering to the local university and rental markets.

Helpful?

Structural engineering projects in Seneca can improve comfort by enhancing your home’s stability on clay-rich soils, reducing drafts, and preventing moisture intrusion. Reinforcing load-bearing walls or upgrading foundations allows for open layouts and larger windows, increasing natural light and airflow. These improvements support better energy efficiency and indoor air quality, making your living spaces healthier, brighter, and more adaptable to your family’s needs.

Helpful?

Before starting structural engineering projects in Seneca, review your property’s zoning and setback rules, and confirm if your plans impact load-bearing walls or require a structural assessment. Mark underground utilities by calling 811, check if your area is in a flood zone, and plan work outside the rainy season. Secure HOA approval if needed, and schedule inspections early to keep your project on track.
