“Onyx transformed our 1987 Sandy rambler into a modern home while keeping its cozy feel. They suggested adding a heated mudroom for ski gear—something we didn't know we needed but now use daily. The team worked around our kids' schedules and left the house spotless every night.”

What Our Clients Say
Real feedback from homeowners and businesses who trust Onyx General Contractor to get the job done right.
“After our Draper home developed cracks following the 2023 earthquakes, Onyx installed 22 helical piers in just three days. Two winters later, not a single crack has reappeared. They even repaired our landscaping better than it was before.”
“Our Avenues bungalow was freezing every winter until Onyx replaced the original 1929 windows with historically accurate thermal units. The house stays comfortable year-round now, and our gas bill dropped 40% last January.”
“The composite deck Onyx built in our Lehi backyard handles everything—trampoline weight, July birthday parties, even that freak May snowstorm. Three years in, it still looks brand new despite our four active kids.”
“When hail destroyed our Sugar House roof, Onyx worked directly with our insurance to get full replacement coverage. Their crew finished in two days before the next storm hit, and the new snow-load rated shingles already survived this brutal winter.”
“Onyx created a legal BYU-approved rental unit in our Provo basement without making it feel like a dungeon. The soundproofing is incredible—our tenants can practice violin without disturbing us upstairs. Worth every penny.”
