SDR Building & Engineering in Chula Vista specializes in fire-damage restoration, flood mitigation, and structural remodeling from its base on West Frontage Road near the Broadway corridor. The firm's restoration division handles IICRC S500 water-damage and S520 mold-remediation protocols, a disaster-recovery workflow that parallels the emergency dryout and rebuild services offered by Xpress Restoration Inc. across the South Bay. Incorporated in 2011, the company also pursues government contracts requiring Davis-Bacon prevailing-wage compliance and federal OSHA 1926 site-safety standards. Custom-home and commercial tenant-improvement scopes encompass tile setting, drywall finishing, and building-envelope restoration. Electrical rough-in and panel upgrades on restoration sites often involve coordination with licensed electrical contractors such as Cano Electric for 200-amp service replacements after fire-damaged panels are condemned. The most demanding scope of work involves structural re-framing of load-bearing walls using LVL beams and Simpson?"HD hold-down anchors to restore lateral-load capacity after fire compromises the original framing.
