With all the new trends in home building, our homes can easily feel outdated and out of shape. While DIY projects are becoming more common, nothing beats the work provided by a general contractor.

With that in mind, we’ve compiled a list of the best general contractors in Ontario, California. Each builder on this list was chosen based on their years of service, the recognitions they have received, and their ability to provide quality work. To meet the best general contractors in Ontario, take a look at our list below. 


Epic Design Build Inc.

1232 Monte Vista Avenue, Suite #4, Upland, CA 91786 

Epic Design Build is one of Southern California’s leading general contractors. Maureen Cunningham and James Johnson co-founded Epic Design Build in 2002. Since then, the firm has built its reputation for building excellent, high-quality homes. Its team is well-versed in a wide range of general construction work.  

The firm’s portfolio features work ranging from residential spaces to commercial build-outs. One of its notable home remodeling works is the Coffee House industrial kitchen. This new kitchen features a rustic blend of wood and steel materials and generates an arts and crafts atmosphere. It sits perfectly in this Craftsman-inspired home located in Los Angeles. 


Lotus Construction Group

405 Saint Augustine Avenue, Claremont, CA 91711 

More than just a builder, Lotus Construction Group considers its services as a personal connection with its clients. Award-winning builder Mark Answorth founded the company in 2011 to bring California a reliable partner in home improvements. The firm comprises builders skilled in design/build processes. The firm’s projects are founded on honesty, integrity, and master craftsmanship. 

But excellent work rarely goes unnoticed as in the case of Lotus Construction Group. Aside from its industry awards, the firm has been given plenty of great feedback from its clients. The firm has been praised for its efficiency, professionalism, and innovative work. The same professional care is evident in this mid-century modern kitchen remodel. Existing walls that separated the kitchen, dining room, and living room were demolished to create an open layout. This created a bigger space and allowed the team to seamlessly integrate it with the outdoor area. 


Anderson Reconstruction

PO Box 609, Glendora, CA 91740

Anderson Reconstruction is a family-owned general contractor specializing in the construction of complex remodeling projects. Greg Anderson and Shannon Anderson are the father and daughter duo leading the team. Their rich, extensive background in construction work has helped refine the firm’s services and train its team of builders. Its services include kitchen & bath remodels, ADUs, water, fire, and wind damage restoration. 

Anderson Reconstruction understands that kitchens are an important part of a home. This is where people gather, prepare, and enjoy a good chat over a scrumptious meal. Over time, kitchens deteriorate and lose their charm. The firm specializes in bringing back a kitchen’s charm through careful reconstruction. Take, for example, this modern kitchen complete with a spacious marble countertop and white backsplash. 


Classic Kitchens

3949 E Guasti Road, Suite A, Ontario, CA 91761 

Classic Kitchen opened its doors in 1984 to serve Ontario with high-end kitchens, baths, and custom home remodels. Jay Adams founded the firm banking on over 40 years of extensive construction experience. The team, under his management, provides custom cabinetry, design/build, and drywall services. 

One of the firm’s notable projects is this kitchen upgrade located in Temecula. The project, completed in 2017, featured a combination of grey and glossy backsplash, Carrera-looking quartz countertops, and brass lighting fixtures. Its warm design is brought out by a wood soffit island matching its wooden flooring. Other elements of this renovated kitchen include an Amerisink AS602 under-mount sink and spacious, smart storage. 


Home Masters International

2232 S Vineyard Avenue, Ontario, CA 91761 

Ontario has trusted Home Masters International for more than a decade to build some of its neighborhood’s remarkable homes. Mark Guirguis built his firm on his deep background in both construction and management. The firm prides itself in providing a full range of services including custom home construction, remodels, and custom installations.

Its great projects have brought the firm a lot of positive feedback from clients. Previous clients have praised the firm’s efficiency, customer service, and overall ability to deliver high-quality work. These are all evident in the firm’s portfolio that features projects from whole home remodels to kitchen remodels. Take, for example, this modern kitchen remodel. It features a sleek kitchen design with monochrome tones of white and grey creating a cohesive look. In addition to its open concept, this kitchen also features cutting-edge kitchen appliances.
