Bathroom Remodel

Willie and his team are great, we had a plumbing issue with the shower water leaking to the first floor. I sent him some pictures and he gave a quote immediately (more complex problems probably require a detailed inspection) and we arranged for next day meeting. When his team arrived, they checked out the leak and confirmed that it would be the price we agreed upon. They worked fast and were creative in their problem solving where another company was unable to solve. They gave a great deal and saved the landlord thousands of dollars compared to the alternative. They gave us a one year warranty for their service which is indictive of the trust in their work. I greatly appreciate that. All in all, I think Willie and his team are professional, prompt, highly skilled, and extremely reasonable in pricing. Would hire again, 10 out of 10!

Kitchen Remodel

I am very pleased with the kitchen remodel completed by quantum construction. Willie was very professional when it came to providing me an estimate, and following through with the plan that was made for the remodel. Willie provided good customer service, and the workers that came to complete the different tasks in my kitchen also provided excellent service. If there were any details that needed to be modified or fixed, willie followed through. I would definitely hire quantum construction again, for future remodels in my home.

“Knowledgeable, Detail oriented, Patient, and Fast” are the words that come to mind when I think of Willie and the Quantum construction team. I approached Willie expressing my interest to have my front door checked out for possible water damage. I dragged my feet for a few months and the whole time Willie was patient, shared ideas with me, but never rushed me, and as soon as I was ready he rolled me into their very well organized process to fix my issue without doing extra unnecessary work that would increase my tight budget. We decided to add a door hangover so the problem doesn’t reoccur. It is clear that NOTHING was left to chance and the project turned out PERFECT due to all the planning and detail that was done UP FRONT!!!! extremely professional and easy to work with. He is constantly learning the new trends in the market and offer unique ideas on how to make your project your own! Quantum is the place you go for top shelf remodeling, major additions or aging in place modifications. This is a full-service, professional organization that doesn’t begin without a detailed plan and drawings(as opposed to the back of a napkin).

I’m so glad I decided to go with Quantum company. Got a few bids from different companies, but I am glad I gave this company a chance. They came out to my house went over the work that I needed to be done. As they promised to deliver and they did!! Amazing job. Some companies give you Fall promises. Not this company, this company means business!! Needless to say I’m very happy with the work. I will definitely will use them for all my properties.. highly recommend them!!

  • What should the customer know about your pricing (e.g., discounts, fees)?

    Good work isn’t always cheap

  • How did you get started doing this type of work?

    I come from a family that has been in construction for 40+ years, so it was only natural for me to take up contracting. Above all construction has always been a passion of mine since I was a young child, I just love that you could take something old and create a masterpiece.

  • What advice would you give a customer looking to hire a provider in your area of work?

    Always look for a contractor that is communicative, responsive, honest, and transparent with what your project entails.
