Re-attachment of Undermount Kitchen Sink

Ali did a fantastic job. Not only was he professional but he really enjoyed the assignment. He understood that knowledge had to be complimented by being able to solve problems and he used his critical thinking to complete the job seamlessly. You could see the passion in what he did. He was very nice and down to earth individual to speak with too.

Of course, Ali is an extension of his leader, RJ who was so pleasant and accommodating and went out of his way to service my request albeit a minor job which many other companies would not waste their time on.

I have already sent out this company to many of my friends as I told them about this wonderful, delightful experience I had.

I was truly blessed by individuals like Ali and RJ.

Thanks to both of you ... Walter Jong

House Renovation

I contacted RJ as my wife and I were looking for a reputable contractor to help us with our home renovation. He was very professional and had near instantaneous responses. Wonderful communication and showed that he really cared about the customer. Can’t stress enough how amazing his communication was. Due to personal and budget reasons, unfortunately we could not proceed with a renovation of our existing home, but we know that on a future project RJ will be the first person we call. If you are looking to do construction on your home, you have to give RJ a call and see if you can make it work. Our experience with him and the rest of the OPUS team has been nothing but positive.

We interviewed 3 contractors and chose Opus because of the fact that they had their own trades that worked specifically for them. The Opus team helped with our drawings and permits and managed to complete our 4 month project on budget and within 9 days of the estimated completion date. They were always responsive and helpful. RJ himself cane and inspected progress often. We had regular updates and site meetings. Opus asked if they had earned a 10 Star rating and whether we would write a review about our experience. I believe they met and occasionally exceeded our expectations and therefore are entitled to this review. Would recommend and hire again.

Excellent Service and communication

I contacted Opus to help me out of a bind with a new window opening for an old house. While I was concerned that it was too small a job. RJ was very accommodating and got a crew in on a days notice.

Given the excellent service and communication provided, I would definitely consider Opus One for other upcoming renos we are planning.

Consultation on Electrical/Renovation Work

RJ provided me with helpful advice on how to find the right professional to complete work on a range hood fan and replacement of electrical unit. He was VERY patient and was able to assess what needed to be done. What's even more amazing is that he spent time to guide me, even though the very small job I described was not something his firm takes on.

Thank you very much for the lovely comments.

RJ mentioned that you had both had spoken and described the situation as being a generally straight forward list of items that (with the appropriate guidance) would be easily resolved.

On behalf of OPUS ONE DESIGN BUILD, it was our pleasure offering you and your family any guidance that you deemed valuable. :)

Structural work

I purchased an old home in need of structural work. RJ is extremely knowledgeable, and transparent.
A true professional in every sense of the word and a great guy to work with. He is methodical, logical and reasonable, explaining all options and costs.
Highly recommend.

Excellent Service

I purchased a condo and a couple of days before closing, the property flooded and there was significant damage. RJ and the Opus team recognized the time-sensitive nature of my request and came out on a Saturday, with less than 24 hours notice, to conduct a detailed assessment of the damage.

Full Home Renovation and Addition

RJ and the Opus Team did a beautiful job on our home. We had some delays with special order materials but Opus did an excellent job managing our expectations throughout those issues. They were always available for meetings. They stayed on budget, and completed the renovation within 11 days of the (original stated) completion date. I am very happy with the finished product, the service and Opus as a whole. Would definitely hire again.

Full Interior Home Renovation 5500 Square Feet

I am a realtor and have sold homes that Opus has renovated and/or built for my clients. So last year when I decided to completely renovate my own home, I contacted Opus along with a couple of other builders that had worked with agents in my office.

I don't think a long drawn out review is necessary. The short version is this. I hired Opus and they will be the ONLY construction company I refer my friends and clients to. The best in the business. Period.
