Read transparent feedback from homeowners, property developers, and structural engineers who trusted JXT Construction with their projects across Somerset West and the Western Cape.
"Jacobus and the JXT Construction team delivered exceptional quality on our new residential build. From the ground excavation to the complex second-storey reinforced concrete slab, the engineering precision was world-class. Jacobus is on-site daily, communicates proactively, and keeps the build strictly on schedule and within budget. Highly recommended for any structural or luxury home build!"
"We had severe concrete spalling and rust bleed on our seaside balcony and external support pillars. JXT Construction diagnosed the root cause, excavated the corroded steel, treated it with anti-corrosive primer, and applied high-grade Sika structural repair mortar with weatherproof elastomer coating. The finish is immaculate and structurally sound. Professional, tidy, and transparent pricing!"
"Extending an occupied double-storey home is always stressful, but JXT Construction made the entire process seamless. The team handled municipal engineer inspections, NHBRC registrations, steel beam installations, and roof truss integrations with zero hassle. The site was swept clean every evening. Jacobus is honest, knowledgeable, and reliable."
"We needed heavy-duty reinforced concrete retaining walls and site terracing on a steep slope in Gordon’s Bay. JXT’s civil engineering background really shined through. They handled the micro-excavation, rebar tying, and concrete pump delivery flawlessly without damaging existing paving or garden areas. 5-star service all the way!"
"Removed two load-bearing brick walls to create a modern open-concept kitchen and entertainment lounge. JXT designed and installed the engineered steel RSJ lintels and support columns with laser alignment. The plastering and ceiling integration was seamless—you would never know there were walls there previously. Truly master builders!"
"Jacobus Theart is one of the few builders who genuinely understands soil mechanics and structural tolerances. Our engineer approved the foundation trenches and steel reinforcing on the first inspection without a single correction. Excellent workmanship, reliable crew, and completed ahead of time."
