"The team was great, especially the leads Earle, Austin, and CJ. They give you a heads up on their ETA, introduce themselves and the plan to ensure they carry out the agreement you had with the first PoC who for me was Jarret Perkins. Also a very great guy as well who will ensure your questions and overall inquiries are taken care of before, during, and after the service! The team who worked even took the time to save the plants that were near the work area and cut around the stone entrance I have so I can put it back together instead of making their lives easier and cut straight through that area of the home. They were even kind enough to seal a small chip in the driveway with the cement they used to close back the holes they made. Which by the way you can’t even see they even worked on due to how they were capable of cleaning and setting EVERYTHING back together. After the service they themselves asked if there was anything else I needed taken care of, as well as were patient (after a long day of work) to answer any questions I had. Still a day or two after the work was completed FSS called to make sure everything was no less than satisfactory. As well as ask you specific questions to ensure the team that came out executed what they were expected to the company’s standards and if not so they can review it in their next meeting. I could tell FSS strives to be the best and are always looking to improve. FSS truly cares for you and ensures you’re left feeling good about the service. They’ll take care of your home as if it were their own."

Types of Foundation Damage in San Marcos

Common Causes of your Foundation Problems in San Marcos

Water Damage

Excess water from leaks, heavy rains, or floods can weaken the foundation by accumulating around it, leading to cracks and structural issues.

Expansive Soil

Certain types of soil, particularly those rich in clay minerals, are prone to expansion when wet and contraction when dry, exerting pressure on your foundation.

Poor Drainage

Improper drainage systems can lead to water pooling around the foundation, increasing the risk of water damage and soil erosion.

Tree Roots

Roots from nearby trees can grow under the foundation, causing it to shift or crack as they expand.

Plumbing Leaks

Leaks from plumbing systems can saturate the soil around the foundation, leading to erosion and weakening of the structure.

Climate Conditions

Extreme weather conditions, such as droughts or heavy rains, can cause soil to expand or contract, putting stress on the foundation.

These common causes highlight the importance of regular maintenance and inspections to prevent foundation damage and ensure the longevity of your home.
