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!"

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."

Structural Engineering questions, answered by experts

The best way to determine if ceiling cracks are structural is to hire a ceiling contractor to inspect the cracks and provide a professional opinion. That said, you might be able to make an educated guess based on the size and appearance of the crack. Larger cracks, cracks accompanied by sagging or discoloration, and cracks that travel from the ceiling down the walls are all signs of structural issues.

Yes, unresolved damage can decrease property integrity and market value.

A structural inspection report will include a detailed description of the structural engineer’s findings, applicable photographs, and recommendations to correct the issue. The contents of the report may depend on the scope of the inspection but might also include a time and cost estimate for recommended work to correct any structural problems found during the inspection. 

The 10 10 rule describes the formula most contractors use to determine how much to charge for a job. Allowing for 10% overhead above the total projected cost to do the work and 10% profit sets a contractor up for success, even if there are delays or other problems on the project. This formula isn’t a hard-and-fast rule, but it is a ballpark figure to begin with when estimating your expenses on a job.

Accurate measurements, sturdy materials, and seamless integration with other structures.
