"Willy was the one who quoted the project and managed every step of the process. He and Francisco and the rest of their team worked very efficiently and completed our kitchen/sunroom project in one day. Their work was excellent and we are very happy with the result. We would highly recommend them."

"I was skeptical at first to hire Greg and have some deck boards repaired, however I would recommend biddle construction 100% and I don t say this likely. They were on time and did a fabulous job on the deck. The thing I admire most of all was honesty. I work overnight and leave my trust to him. Whenever there was an issue, he would call me to come and see it. Not just covering up the problem. Honest people are hard to find but I thank God I found biddle construction. I have a few more things to get done at home. I will absolutely 100% recommend biddle construction. Thanks Greg and Edwin. Godbless."

"Mike the owner, was very friendly, guided us thru the best type of paint to use for our project. Great job! Would highly recommend"

"Robert was willing to work around my crazy schedule. I had several random things that I needed done around the house (blinds hung, bathroom vanity light replaced, ceiling fan repaired, the lock on the patio door repaired, the privacy fence gate repaired, and light bulbs replaced on another ceiling fan that was mounted too high for me to reach). He explained what he was doing as he worked, worked efficiently and quickly, and his rates were beyond fair. I will be using his services again!"

"These guys are the real deal! They are kind, prompt, communicative, and diligent. They helped me patch and paint a hole in my ceiling--they came for a short time over the course of four days to make sure it was done right. I'm so happy with their work and would highly recommend them to friends and family. I will certainly be keeping their contact info for future needs. I would give more than 5 stars if I could!"

"I worked with Rob directly. Efficient and professional. Would hire again"

"The professionalism and quality was superb. From the very first consult to the last day the owners were available to answer any questions. They walked thru the process from step one. Wendy even assisted with design. Staff always cleaned up everyday and they even became friends with my two dogs. You hear about nightmare remodels but mine was wonderful and it was a large job. Can’t wait for them to do my next project."

"I recently hired Diamond Interiors to remodel my home, and I couldn’t be happier with the results. From start to finish, their team was professional, detail-oriented, and truly committed to delivering top-quality work. Every step of the project was handled with care, clear communication, and craftsmanship that exceeded my expectations. The transformation of my home is incredible—beautiful finishes, clean lines, and thoughtful touches throughout. They stayed on schedule, kept the workspace tidy, and made the entire process stress-free. It’s rare to find a contractor who combines skill, reliability, and pride in their work the way Diamond Interiors does. I highly recommend them to anyone considering a remodel. Outstanding job—thank you, Diamond Interiors! From Dan W."

"In addition to exterior painting, we also had some interior painting completed and power washing of a lot of concrete outside the house as well as the house itself. Work was of high quality and completed very professionally. VERY SATISFIED"

"Dandy Handy also known as Kevin did an excellent job for me. He was on time, courteous, and confident. He came to my home, assess the problem and went and found the proper material to fix my storm door weather stripping. His pricing Was fair. Strongly recommend him for any handyman jobs."
