Cost Of Basement Foundation Walls
A structurally sound home starts with a strong foundation holding its weight and consequently, it can be considered the most important part of the house. For this example, we'll consider the cost of a new 1000 square foot foundation. The average installed cost is $5-$8 per square foot, or $5000-$8000.
Foundation replacement in smaller homes may cost in the $30 - 50,000 range, depending on the variables mentioned earlier. A large home or one with a large number of constraints could run to more than $100,000. Not inexpensive but a lot less than a new house.
Repairing a simple crack in a poured concrete foundation can cost about $400-$800, depending on the extent of the damage. Replacing an entire basement floor can add another $200-$400. And in earthquake-prone areas, reinforcing the foundation with anchor bolts runs $1,500-$3,500 or more. Poor soil causes the most damage.
I have a 20 foot wall, one side of the wall is bowed by 0.25 inch, basement guy wants to place 3 beams to support the wall for $2400. Sounds really high to me. It's about 2-3 guys a single day's work, materials are cheap. I'm having an engineer evaluate the job ($295 for that).
The cost to Waterproof a Basement starts at $8.39 - $9.95 per square foot, but can vary significantly with site conditions and options. Get fair costs for your SPECIFIC project requirements. See typical tasks and time to waterproof a basement, along with per unit costs and material requirements.
A structural engineer has indicated that I need to replace part of my basement wall due to water damage, bowing and cracking. The house was built in 1924 and the concrete used back then is full of sand. The basement floor is dry, but the basement support wall is buckling. We need to either shore it up or tear it apart from the outside, and repour concrete using rebar reinforcement.
