LUX Foundation Solutions is a fully licensed and insured foundation repair, waterproofing, crawlspace repair and masonry service contractor. Providing services to a large part of central and Northern Virginia. With Combine Experience of over 25 years!
"Very, very disappointing experience; Lux replaced the foundation of my 1850 log cabin. The design was bad, the communication was bad, the execution was bad. Throughout the entire process, they were making mistakes. I now need to pay another company to fix the mess they left behind. I would strongly suggest not using this company!"

"Do not work with JES. They contracted with us for a job they were completely incapable of completing. We paid our deposit in Dec, work was supposed to begin in Feb. For months, crews would show up, complain about how narrow the space was, say they didn't have the proper equipment to do the job, then leave the site. We worked with them while they replanned how to complete the project because they claimed the person who bid the job screwed up. Further complicating matters, they were digging too close to the sewer pipe and constantly damaging it. We had to constantly hire plumbers to repair the pipe and remediation companies to deal with the sewage. We finally fired them after they let a leak go for a month where they not only didn't tell us about it, but denied that there was a leak when we asked whether that was the problem. Everyone at every level blamed somebody else, and it took threats of lawsuits to get the contract canceled and our deposit returned. The fecal matter ran deep."

Exterior Waterproofing Experts is a Class A General Contractor in the state of Virginia since 1997. Our service protects your home against wet basements, water leaks, flooding, water seepage, foundation leaking, and wall seepage. We have been doing subcontract grading and drainage work for many years. We have completed many waterproofing contracts for residents of Fairfax County, including: Fairfax, Alexandria, Arlington, McLean, Great Falls, Potomac, and Vienna, Virginia (VA). We are now offering to work directly for clients, passing the savings on to the homeowners. It is our belief that water problems are best solved from the outside before water gets into your home.
"My basement had mold and evidence of water damage in July/August, and I was referred to Exterior Waterproofing Experts. The majority of the mold was on the side of my house, but the salesperson made a strong pitch about the need to waterproof the front of my home by digging up the garden down to the foundation. My wife was largely convinced, so we went ahead with the $8000 project. Six months later, the insulation behind the waterproofed front of the house is sopping wet. When the salesperson came back to my home to take a look, his explanation was that the water probably came up through the floor. His words were along the lines of "99% of the time the water comes up through the front." At this point, I feel like I have an expensive solution to a problem I didn't really have."

"JES Foundation contracts all their electrical work out to Root Electric. In the process of installing my new sump pump, back-up sump pump, and sump pump alarm system, it was determined that a new dedicated outlet could not be created due to my existing electrical panel being too small. Thus, I needed to get an electrical panel upgrade. Through JES Foundation, a date and time was arranged to have my new electrical panel upgrade installed. The lead Root electrician Andrew, and his assistant Andy, dd a terrific job installing the new upgraded electric panel. They were both very friendly, efficient, and professional. Andrew afterwards walked me through everything that was done, and answered any questions that I had. They also cleaned up afterwards very well. I highly recommend Root Electric and JES Foundation to anyone who needs their expertise."

"Avoid them...their own intall tech walked into my house, looked at the work order and -incredulously- declared to me that 'whoever wrote this up...they were probably new. But this isn't going to solve your problem". That ACTUALLY HAPPENED. Drying Company completely botched the job. They failed to finish the work (offered some laughable small credit instead) and then sought civil remedy for an amount I don't owe. Oh, and they kept the deposit. To summarize: THEY BOTCHED A JOB AND THEN SUED THEIR OWN CUSTOMER. I was going to let sleeping dogs lie but now I'm going to use every consumer digital megaphone available. Just look at the photo! They were hired to spray foam my crawl space!! That's what they left...They claim this crawl space has been mitigated for pipes freezing."

"I hired Paul to guide me through the ridiculously complicated permitting process in DC for repairing an existing exterior stairway in a historic district. Before engaging with Paul, the city was telling me I needed to demolish the stairs and rebuild them to code. I worked with an architect and it became clear that it was impossible to bring them up to code. Still, the city refused to back down and said the stairs couldn't be repaired. I then hired Paul, who recommended a number of improvements that would make the stairs safer without demolishing them, created a report, and then convinced the city with all of the relevant code citations. It became clear that Paul was far more knowledgeable than the city officials of their own regulations. While the process was still a labyrinth to navigate, Paul helped me overcome every hurdle that the city placed in front of me. I highly recommend Paul. I wouldn't have been able to get this work done without his expertise and his advocacy for me."

Structural engineering services FAQs
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.
