"Tony Hall was awesome. I know of JES since they started in the area but never had any reason to request a free inspection until I wanted to assess the condition of my crawlspace prior to selling the house. I learned so much about the function of a crawlspace and the current condition of mine. His inspection did not reveal any emergent issues with my 25 year old house but he did take the time to show me about encapsulating my crawlspace which will improve insulation properties and keep the area just about maintenance free. Included is a 25 year warranty which is transferable should I sell the house. I completely recommend JES and their inspector Tony Hall. I will be calling them to inspect and make recommendations to my next home when purchased."

We are a Christian owned, residential builders and home improvement company. We believe serving you and your family is our first priority. There is no job to small or large for our our dedicated team. Message us today for a free estimate! We offer a design service with 3d realistic design renders for your projects to visualize the outcome. Ask us about our budget kitchen and bathroom. We can design your space based on your budget, while focusing on achieving your desired look. Financing and monthly payments available.

"Overall the quality of work turned out nice. However, the experience with DFC Home Improvement was not exceptional. The administration process was messy to say the least. This ranged from permits being disapproved due to submitting incorrect blueprints to the county and long winded conversations with the owner Brian. A word of advice is to screenshot and save all quotes DFC Home Improvements sends out, as I believe they are modified and update previous versions on their site. Ultimately, we were happy with the quality of work. The project was completed in six weeks, when expected to finish in five. The total cost was $45,950 when the quote was for $38,750 about 18.5% over estimate. I have other projects that I wanted to complete in the future, but I think I will find another contractor for those."

Structural Engineering questions, answered by experts

The depth of any foundation style depends on your climate and how deep the frost line is, as building code requires that the footers of a foundation—which are built into a monolithic slab—sit at least a foot below the frost line. At the southern tip of Florida, for example, a monolithic slab foundation would only need to sit 12 inches under the soil at the widest parts. On some parts of the Canadian border, the frost line is 100 inches, which would mean a minimum of 112 inches, which is prohibitively deep for a monolithic slab.

Yes, water damage can affect your walls' structural integrity. If the water or moisture sits on the walls for an extended period, it can weaken the drywall, plaster, wood framing, and other materials supporting the wall. That's why it's critical to dry out the area as soon as you notice it.

Signs of structural damage include foundation cracks, roof leaks, bouncy floors, crumbling concrete, and cracked or leaning chimneys. Structural damage can make itself apparent in various ways, and sometimes, there may not be obvious signs. Inspect your foundation and roof annually to stay ahead of potentially serious structural problems. 

The standard thickness for an LVL beam is between 1.75 inches and 7 inches. However, you can order LVL beams in non-standard sizes as well. When you work with a contractor, they can source beams that are the appropriate size for your project for you after assessing your blueprints.

Many horizontal cracks in home foundations result from water and soil pressure from outside of the building or from a footing that is shifting. Under those circumstances, horizontal cracks are a structural problem that requires repair before they become worse and more difficult to fix. However, in very specific cases, thin horizontal cracks may simply be a cosmetic blemish due to concrete shrinkage.
