Latest review:
I first hired Bina Build through Home Depot to patch some drywall in my garage and laundry room. I was so happy with their work that I had them do much more. They installed a new exterior door, upgraded my foyer with new tile and paint, and redid my powder room with a custom porcelain floating vanity and high-end finishes. They also renovated my basement, including new flooring, paint and the stairs, and my dark basement is now bright. Everything was finished on time and the quality was excellent. I'd highly recommend Bina Build.

Electrical inspections & PAT testing- 2 May 2026
Don't let the "New" badge fool you—Marco is a pro! I’ll admit I was hesitant to hire Marco at first because he was listed as “New” on HomeStars with zero reviews. However, I saw he was ESA qualified and decided to give him a shot. I am so glad I did. His quote was significantly lower than other bidders, and most importantly, the price he quoted was the price I paid—no hidden fees or "add-ons." The quality of work was excellent; he didn’t rush, and his craftsmanship was neat and clean. What impressed me most was his customer service. Marco is professional and considerate—he even checked if my computer was on before cutting the power! He patiently answered my long list of questions without making me feel like a bother. He was also incredibly respectful of my home; without even being asked, he made sure to take his shoes off every single time he entered. If you are looking for someone knowledgeable, affordable, and honest, hire Marco.

Install or repair bathroom fixtures- 6 Nov 2026
Ali is so professional, so competent, so respectful, so knowledgeable, so resourceful, so good in what he does. Most importantly, he is probably the cheapest in town. You do not need to look for anyone else. Ali will get it done. My shower mixer was broken. The model was an old design. He taught me how to find the right model and when I got it, he came right on time and did the job perfectly. He even helped install a new valve to help me manage my main water tap, to prevent any future problem. So, do not waste time asking for quotes. Some companies want you to pay $50 or $90 visit fee. I totally reject every one of those. Another came without visit fee, but gave a ridiculous quote. So, learn from my experience. You will be very happy to hire Ali. He is truly God sent. His assistant, Sara, is so pleasant and very nice to speak with I can see she is such a great help to Ali. Thanks, Ali. Thanks, Sara. I will definitely refer people to you.

I’ve worked with Josh from Norground Electric on multiple projects, and I can’t say enough good things about him. He’s reliable, professional, and really knows his stuff. Whether it was landscape lighting, step and driveway lights, or hooking up pool equipment, Josh always made sure the work was done right and looked great. He communicates clearly, shows up when he says he will, and takes pride in doing a clean, quality job. It’s hard to find electricians like Josh these days — I wouldn’t hesitate to recommend him to anyone looking for any electrical work.

Install or replace pool heating system- 10 Sep 2025
Geoff at poolcraft and his representative Ed who came to the house immediately the following day quickly assessed our issue who advised we needed a new heater. Poolcraft immediately ordered a better heater delivered that day as promised and the next day installed as promised. It was a seamless and easy process and we could not appreciate it more considering what we had to go through two weeks prior. I would definitely recommend pool craft for your pool care and maintenance which is what I'm going to do from now on. Thank you again for your professionalism efficiency and attention to detail.
