• Foundation Construction ADU and complete foundation construction

Bristol FX doesn’t just repair foundations – we build them from the ground up for your dream projects. Whether you’re adding an ADU (Accessory Dwelling Unit) or Casita to increase your property value and rental income, planning a room addition to accommodate your growing family, or designing structural concrete features that enhance your outdoor living space, we engineer and construct foundations that last generations.

Our new construction services go far beyond pouring concrete. When you want to remove interior walls to create that open-concept living space you’ve always envisioned, we don’t just knock down walls and hope for the best. Our engineers calculate exactly what structural support your home needs, then we design and install the proper steel or engineered wood beams that safely carry your home’s load while giving you the spacious, modern layout you want.

For ADU and Casita construction, we handle everything from initial soil analysis and foundation design through final concrete placement. These structures require specialized foundation systems that meet current building codes while integrating seamlessly with your existing property’s drainage and utility systems. Our retaining wall construction creates beautiful, functional outdoor spaces while solving drainage and slope stability issues that enhance both your property’s usability and value.

Every structural concrete project we undertake is engineered to exceed building code requirements because we understand that cutting corners on foundations and structural work creates problems that last for decades. Whether it’s a simple patio extension or a complex multi-level addition, we ensure your project looks exactly like you envisioned while providing the structural integrity that protects your investment.

With over 14 years of foundation expertise, Bristolfx brings the same precision and lifetime warranty commitment to new construction that has made us California and Arizona’s most trusted foundation repair company.
