We strive to exceed your expectations in waterproofing, mold remediation and foundation repair. We take pride in our work, that’s why we don’t employ subcontractors. We understand there are a lot of choices out there when choosing a certified installer – we hope you choose us! Protect your home and health from mold and mildew invaders. In our 28 years of experience, we have never encountered a wet basement, crawlspace encapsulation or mold removal condition that we couldn’t handle. Give us a call today for a free, no obligation inspection and professional basement waterproofing system tailored for your home or commercial project. AA Action Waterproofing is licensed, insured and bonded with a A+ Rating with the BBB. Please call us and we’ll happily supply you with references.

"Our 25+ year-old French drain system in our 100-year-old basement was showing signs of failure, so we contacted several companies to get advice on what to do. Jason of AA Action was very professional and helpful when he performed his initial inspection of our basement, and had very good ideas on what needed to be done. The price he quoted for the work was also, based on what we had read, reasonable. We ended up going with another company recommended by Angi, but only because it brought up a couple of options that we had not thought of, and we felt comfortable with them doing the extra work. We were not at all unhappy with AA Action's suggestions or pricing - it's just that the other company's additional ideas made sense for our circumstances."

Structural design for residential and commercial. New , renovation, addition and underpinning. Licensed professional Engineer in DC, MD and VA We take great pride in our experience, expertise, quality and customer service that we provide to meet every consumer's needs.

"Working with Zign Consulting has been the bright spot in an otherwise complex construction project. From the beginning, Zign Consulting was everything you hope for: honest, direct, highly capable, and urgent. After months of delays and complications caused by a previous architect, Zign Consulting stepped in and immediately brought clarity and direction. They swiftly got our plans completed and approved by DCRA—something the original architect struggled with for nearly a year. Their communication was transparent, their timelines were accurate, and their professionalism was unmatched. If you're looking for an architectural consultant who will advocate for your project and get things done the right way, Zign Consulting is the firm to hire. I can't recommend them enough."

FAQs for structural engineering projects in Washington DC, DC

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.

Yes, all states require structural engineers to carry the proper license, with specifics determined by each state. You can use Angi’s state licensing tool to confirm that the structural engineer you’re considering holds the required licensing to tackle your job. Hiring an unlicensed structural engineer will not only cause issues with permits but it could also lead to an unsafe building. The cost of a professional, licensed, and experienced engineer is well worth the investment.

The process of hiring a structural engineer starts by finding reliable professionals in your area and comparing quotes from at least three of them. From there, you can narrow down your selection by asking some leading questions:

  • Do you have experience working in my specific area?

  • Do you have professional indemnity insurance?

  • What will your structural report cover?

  • Do you charge a flat fee for a structural report or by the hour?

  • How long have you been in business?

  • Do you have a list of customer references?

Structural engineers typically charge between $100 and $250 per hour, but many jobs won’t be based on a per-hour fee. Instead, the structural engineer will offer a flat rate for the inspection and structural calculations. The flat rate for a structural engineer costs an average of around $550, but you could see prices ranging from $300 to $800, depending on the complexity of your project and how easy it is to access certain parts of your home for the inspection.

Whether you’re building a new home or building an extension on your existing property, you will likely need both a structural engineer and an architect. A structural engineer will determine what loads your foundation and framing can safely handle, and an architect will draw plans according to those structural calculations to simplify the building process. You can start by contacting a structural engineer near you, as many work alongside architects and can get all of the prep work done at once.
