Platinum Home Builders & Design, Inc
General Contractors in Ontario
Average rating: 5 out of 5 starsOctober 20, 2021
“So pleased with my new shower from Platinum Home Builders & Design! The process was so quick; I had my dream shower installed in A Few days ! I didn't think that was possible - I had the same shower tiled in '08 and it took nearly a month to install. I couldn't take looking at the moldy walls any longer - no matter how hard I cleaned nothing helped. I am so thankful for the Microban feature; it keeps my shower clean and keeps me protected. Everyone I spoke with/interacted with was so friendly - this experience was a true pleasure. Thank you, Platinum”

“I had all three of my bathrooms remodeled by Home Accents. Jay created the perfect layout and walked me through the entire process. Each worker that come through my home was exceptionally professional, friendly and skilled at their job. My floors were covered each day, they vacuumed each day along with making sure everything was put away properly. They followed the scheduled perfectly, and there were no major surprises or hidden cost. Out of my four estimates, I am very happy I chose Home Accents. The entire staff was remarkably efficient, helpful, kind which is something rarely found today. This is a very up scaled business with competitive pricing, great customer service and focus on detail.”
Cutler Construction Services, Inc.
General Contractors in Ontario
Average rating: 5 out of 5 starsJuly 13, 2014
“Cutler construction renovated three bathrooms for us, two on the second floor. That included tile flooring (with special materials to avoid cracking), custom vanities, granite counter tops, lighting, exhaust fans, and mirrors, as well as painting. They replaced several ceiling fans, all of our smoke detectors, and added CO detectors. Their work was professional and high grade: no bs, no missed deadlines, no cheating on quality, just total honesty and great craftsmanship. We are extremely pleased and will use Cutler construction in future projects.”

“Can't say enough about Patrick! My wife and I were looking for a contractor to replace our original fiberglass shower/tub combo and replace it with a large walk in shower. Patrick completed an estimate that we were happy with as it was very reasonable compared to other contractors. We showed him the layout/concept we were looking for and the end result was nothing short of awesome. This project was upstairs and care was taken to protect our flooring and stairs on the daily. Clean up was performed daily with minimal impact on daily living. Patrick was always courteous, returned phone calls in a timely manner, always answered questions and kept us updated on the status of the project. He handled any changes very well and listened to our ideas and made it happen. Our particular project from demo to completion was 3 weeks. Thanks again Patrick!”

If you're on the brink of a large home improvement project, remodel, or new build, you'll likely want to hire a general contractor in Ontario, CA. These professional contractors manage all aspects of the job to ensure it's completed on schedule and to your satisfaction. Whether you’re trying to find Ontario building contractors for a new construction, or home renovation contractors to spruce up your existing place, it’s important to know exactly what role they will play in the project.

What is a general contractor?


General, or construction contractors, are often known as project managers. They oversee the entire remodeling or new home construction project and facilitate all day-to-day tasks that move it toward completion. A Ontario general building contractor will work with your architect to review plans as you build a house and ensure everything is in place before work is started as well as arrange for permits and necessary inspections. While good local home improvement contractors in Ontario will have the skills to handle certain tasks onsite, such as carpentry, he or she is also responsible for hiring subcontractors for the majority of jobs, such as electrical work, painting or plumbing. In addition, home renovation contractors should be on-site regularly to inspect the progress and resolve issues.

General contracting services are a must for successful completion of a renovation. Because of this, it's essential that you do your homework before deciding on the right professional contractors in Ontario as you remodel or build a house. Inspect bids carefully. Was it ready when the contractor promised it? Was the bid for building a home unusually high or low? Each of these things can be very telling: A late bid may reflect timing standards, and an off-the-mark bid could be code for a pricey premium or a deliberate underbid to score the remodeling job. You should call references, carefully read reviews and visit completed projects in Ontario, CA to see if they’re what you expect for your job. Once you secure your local Ontario contractors, read the contract very carefully to be sure everyone is on the same page.

Questions to ask prospective Ontario general contractors:


  • How long have you been in the business?
  • How many projects like mine have you completed?
  • Who will be working on the project?
  • What qualities do you look for in your subcontractors?
  • Can you provide me with references?
  • Are you licensed and insured?
  • How do you charge, and what does that include?
  • What happens when costs exceed budget, whether due to materials or labor pricing changes? What about changes made by the client or by the professionals — what kinds of situations would cause those costs to be incurred?
  • Can you give me a written estimate?
  • What do your services include?
  • When can your job get done?
  • What will I need to provide?
  • Are there any important considerations or concerns you foresee with this project?
