What Our Clients Say

ADUs Reviews

I want to thank GLC Kitchen & Bath for helping me. I especially want to give thanks to Liron. I was not sure that this company was able to help me on my particular project, but the girls on the line were so kind and reassured me my scope of work was something they were able to help with. Liron came out, described everything that needed to be done in detail. I found pricing to be fair and reasonable. I'm happy to have found a great, reliable small business company too help repave my driveway.

I did a full demolition and rebuild on our hillside property. Once our plans were ready I reached out to a few contractors that I found online. Some didn't answer at all and some took weeks to answer. GLC always got back to me no matter what questions I had, after our initial conversation we met at the property and they gave me an estimate. I decided to go with them. They weren't the lowest bid, but it was reasonable and I liked the personal service and attention we would receive, and that they had been in business for longer than the rest. I was pleasantly surprised that the communication didn't just last until I signed the contract. My project manager always got back to me within an hour or so and usually was reaching out to me keeping me updated and informed. He made sure I was happy with everything and really seemed to care about the result. They didn't cut any corners and kept an eagle-eye on everything, their team is extremely detail oriented. Beyond my expectations. If you are doing any kind of major construction I suggest checking them out. Thank you so much

I reached out to GLC Kitchen for an inquiry on resurfacing my kitchen cabinets and the turn around and the QUALITY of work was outstanding! They really paid attention to detail. Eden, the project manager was super helpful in suggesting ideas to make my cabinets look modern and stylish. I look forward to working with Eden on my next home project!

I needed to get new cabinets in my kitchen, they were dated and I needed to bring some life to my kitchen again. I had a few contractors come out and I felt most as ease with GLC Kitchen and bath. Their customer service from the first initial phone call to the project manager helping me out, I couldn't be happier with the smooth process. Benji brought me to showrooms to give me some ideas on what would look great in my kitchen. I couldn't be anymore happier with the end results!

I've had some bad experiences with contractors over the course of the years when renovating my phone and doing multiple projects. It always had me be more cautious on who I hire to do the job. Since COVID, I wanted to support some local businesses and thought I'd give GLC Kitchen & Bath Remodeling a chance. I met with one of their project managers Sagi. I expressed my concerns and previous experiences with contractors on jobs I've done for my home. He made me feel comfortable about working with him. He suggested some great layouts that worked with the budget I have. I'm looking forward to the final product!

I just want to say that Omri was great. He took me to showrooms, helped guide me in design making. Everyone was all very professional and helpful. The quality is worth every penny I spent! I'm looking forward to doing my next project with them, which will be my bathroom!

Eldan led us thru this rather challenging remodel (in the mist of a pandemic) and happy to report that it was all worth it at the end. The kitchen came out better than we had anticipated. It really transformed our home. The craftsmanship with cabinets, tiling, countertop and appliance installation was excellent. I would recommend GLC for anyone looking for a major remodel.

We talked to several contractors before deciding on Goldenline Construction! I have wanted a new kitchen for over 40 years and needed one for over 30, I wanted this to be perfect! I am so glad I went with Goldenline, Eldan was wonderful! His foreman and crew were wonderful!!! They were very professional, helpful, and always were very careful. My dream kitchen is now finished and I would highly recommend them to anyone and everyone. I wanted a happy kitchen that was completely different from my old one. I went from 7 cabinets to 15, I couldn't be happier. My husband and all of our friends are happy too because I am baking and cooking again :) We are now saving up for Goldenline to do more work around here :)
