★★★★★ - "Timely and trustworthy! My new basement windows look great, I wish I’d had David replace them sooner. He made me feel comfortable enough to leave him working in the house alone while I ran an errand. He also cleaned up after himself. Nothing better than finding someone you can trust that also does good work!"

★★★★★ - "I truly can't say enough good things about the service David provided with the installation of my patio doors. From start to finish, his work was absolutely impeccable. He was extremely respectful, detail-oriented, and took great care to protect everything around the workspace. Not a single mistake was made — everything was done with precision and professionalism. Beyond his excellent craftsmanship, David was kind, courteous, and very proactive. He even offered to help move and rearrange some furniture to make sure everything looked perfect before he left. That level of care and dedication is rare to find. Everyone should work the way David does. His work is truly flawless, and his attitude makes the entire experience stress-free and pleasant. He truly made my life easier, and I'm incredibly grateful for his help. I would highly recommend him to anyone without hesitation."

★★★★★ - "We just hired David's company DiezSant Home Improvement to replace our 27-year-old roof and gutters. It was a pleasure to work with him and the project was done perfectly. One day for the roof and he took care of the gutters the next day. Everything came out beautifully! He does business the right way, honesty and quality work without the hype that comes with the bigger companies out there. Now that the roof is done, it shows I need to look into windows and siding soon. Highly recommend him!"

★★★★★ - "David and crew came to the rescue! DSHIC offered reasonable and honest solutions for our roof problem. They were prompt and thorough and kept us informed through the whole process. Never tried to upsell and instead offered options for a better long-term investment. A couple of the neighbors even asked him to take a look at their house while his crew was working on ours. Would recommend to anyone and will for sure use their services for future home improvement!"
