"I worked with Alpha once before, and they assisted with a second project 2 years ago which, now finally completed, I'm able to write a review about. Alpha helped with structural plans for windows in a garden level unit in order to prepare the proposal for city approval. Alpha is a big company and it took them a little while to complete everything; however I can certainly say that the engineer and contact people were knowledgeable and thorough. The plans were approved with their help and now that the unit is permitted for occupancy, the windows are a lovely attribute to the space."

"The work Erdelyi associates did is great, but communication and timeliness were lacking. I didn’t have a consistent point of contact throughout the project - it just seems my project was handed off from one person to the next with no continuity and I had to proactively reach out for updates."

"Satisfied customers reporting! We're writing this review four months after the completion of our bathroom renovation. We've been thrilled with the final product and the experience of signing with Ouri from day one was a pleasure. This was our first large project and we would undoubtedly hire Ouri again. Project We instinctively knew Ouri was the best fit for us after the on-site consultation. Not only are his reviews overwhelmingly positive, but he's knowledgeable, respectful, patient, and honest, with competitive pricing to boot. He's also a very responsive communicator. We needed some time after signing the contract to shop for materials. Ouri kindly rolled with our uncertain timeline, checking in periodically without any pressure to see where we were at and advising on any questions we had along the way. From the beginning of the project, his crew was respectful, clean, and always checked in with us as any questions came up. The project went smoothly and for one very minor hiccup that came up, Ouri & crew were quick to address without question. And months later, he sent a member of his crew to come troubleshoot something minor, again without any hesitation. It's challenging to keep these brief when you have such a great experience, especially when you read and hear about horror stories from other people. Selfishly, maybe we should keep this to ourselves so he isn't so busy when we need him for another project in the future :) Scope The bathroom was totally gutted save for some sections of drywall. A full tiled shower with a bench was installed (replacing a tiny old corner unit!), along with added lighting & exhaust fan, new floor tile, and all new fixtures/ cabinets/ paint. The plumbing and the shower drain were relocated. An old window was removed and replaced by a new one on an adjacent wall."

"Stuff happens, and this business knows how to handle it! We had a stain on the ceiling. Ofri from BTB came over and turned on the water from the upstairs bathtub and then the shower stall. The ceiling became moist after the shower was turned on. Ofri then came back with a plumber. He turned on the upstairs bathtub. After they left, water dripped from the ceiling. Ofri had the plumber immediately send over a team for a service call. They broke open a hole in the ceiling and found that a pipe leading to the bathtub was so rusty it had holes. They took videos showing other pipes leading to the bathtub were also very rusty. While the team was still there, Ofri gave us prices, sent over the paperwork and the pipes were replaced within a of couple hours. Fabulous! Ofri had thought it would take a lot longer to complete the plumbing work. Therefore, her pricing did not align with the actual work performed. She brought in Alon, who substantially reduced the price to our satisfaction. Their responsiveness and reasonableness earned them my highest rating. Thank you Ofri, Alon and the BTB team!"
