What Our Clients Says About Prime Custom
Posted on Google Y CTrustindex verifies that the original source of the review is Google. We had a great experience with Prime Custom Kitchen & Bath for our kitchen renovation. We wanted a European-style kitchen and that is hard to find in this area. Most stores that sell European cabinets don't offer installation and you have to contract a company that knows how to work with European measurements. We found Prime Custom online and decided to make a visit to their showroom. We didn't have an appointment but that was no problem. Filiz explained to us that they take care of the entire process from design to finish. She showed us the kitchen lines they carry and Alusso is exactly what we wanted. We decided to have Filiz start the design process and gave her our requirements. When she came back with the first drawing it was evident that she had carefully listened to us. We also met Kamil, the owner. He is very involved with everything and said it is most important for him that his customers are happy. It convinced us that this was the right company to renovate our kitchen. The whole process went fast and smoothly. Not only did they have to replace the cabinets but they also had to change electrical wiring, plumbing, gas lines and vents. They also designed and built a unique gathering counter and incorporated some last-minute changes we requested without any issue. It is incredible how fast and skillful the crew delivered. Their project manager Idris was on top of everything and always kept us up to date with the schedule. He was very responsive and transparent. The entire renovation took just 20 days and the result is amazing. They transformed a generic dark builders kitchen into a light, spacious modern kitchen. It was a real pleasure to work with them! They always showed up on time and cleaned up at the end of the day. As far as we're concerned, they completely lived up to their "happy customer" principle.Posted on Google Jacob KTrustindex verifies that the original source of the review is Google. Very good service and best skilled installersPosted on Google Meltem KaraagacTrustindex verifies that the original source of the review is Google. Prime Kitchen Cabinet installed a deck successfully in my house. Kamil is very experienced in technical matters and also material procurement. He is very polite and customer friendly, and a great manager. During the installation deck, everything was smoothly progressed. Installation was done quickly and perfectly. There was not a technical problem in the project. The inspection processes also passed quickly. The assembly team came to the work area early every day, worked disciplined and left the job site clean and tidy when leaving the work area. If we have a new project in our house, I will prefer Kamil and his team again and I recommend it to my friends.Posted on Google Poweide KoroyeTrustindex verifies that the original source of the review is Google. I may be Prime Custom’s pickiest customer ever and I commend them for the kitchen renovation they did for us. As an accountant, project manager, and lapsed (building) engineer whose first job was in sales, the Prime Custom team had no idea what they were getting into. In Kamil, I found someone whose attention to detail matched mine. The pride he takes in his work is rare these days and he is a true craftsman. Kamil’s customer focus is also refreshing. Our project was not especially large, but as I am so particular and had the added responsibility of creating perfection for my wife, we were VERY demanding clients. The finished product is beautiful and continues to draw compliments a year and a half after its completion. Perhaps even more impressively, when I noticed defects on some cabinet doors about ten months in, Kamil worked with the supplier to replace them and provided updates when their delivery was delayed. The rest of the Prime Custom team helped make the kitchen unique with the choice of materials - the backsplash and counter, which Filiz helped us choose, remain talking points; and interesting design solutions – who knew that the placement of under-cabinet lighting and power outlets could be so impactful? I apologise for the length of this review but given Prime Custom’s effort in delivering our kitchen, it’s a fraction of what it could be. More importantly, choosing the company for your home renovation project is a decision you won’t regret.Posted on Google Calvin LiTrustindex verifies that the original source of the review is Google. We used Prime Custom service to renovate our kitchen, and they did an amazing job. Due to COVID 19, the project ran longer than usual, but it’s understandable. Kamil and his team worked very hard to deliver our dream kitchen with all the constraints. They accommodated our change requirements, fixed issues we didn't aware. Project manager and the contractors were always polite. The cabinets we ordered were high quality, and the team’s workmanship was very good. Upon installation of cabinets, they spotted few cabinet doors had quality issue, and immediately re-ordered them for us. There were additional work orders in this project because re-routing of the pipes, fixing gas line and other stuff. Kamil and his team explained well the additional work required and didn’t do things that were not necessary. We worked with Filiz to design our kitchen, they exceeded our expectation. She gave us idea to tear down the wall to expand the counter space and the overall space of kitchen. She worked with us to pick the cabinets, tile, countertop and other materials. Overall, I am a very happy customer, and I love my new kitchen.Posted on Google Supreet SinghTrustindex verifies that the original source of the review is Google. I highly recommend Prime Custom Kitchen & Bath for kitchen remodel. They finished my kitchen remodel earlier this month and I am in love with my new kitchen. We started planning the remodel in January of 2021 and went to a few companies for quotes and to see their products. We thought what we wanted was only available if we went full custom kitchen route and spend way over our budget but Prime found the exact product that we wanted and kept us in our budget. DESIGN: Their designer Filiz Ince is extremely talented and knows kitchens inside out. She has really great ideas on how to upgrade from generic kitchen to a custom kitchen. She was very attentive to what I wanted in my kitchen and never once said "that's not how people do it", which I heard from other places. For example, I did not want corner upper cabinet and Filiz suggested Blind corner cabinet right away which was exactly what I wanted. She sat with me for a long time going over the full design, she pointed out the irregularities in my old kitchen (how sink wasn't centered to the window) and fixed them. She loves designing kitchens and It Shows. Due to COVID, our cabinets were coming in September even though we placed the order in April, Filiz kept in touch with us and updated us on any news from the supplier. She helped with choosing countertops, faucets, lights, and hardware. She is a full service designer! INSTALL: We decided to demo old kitchen ourselves to keep the costs down and Prime had no objection to it. They were happy to do as we wished. Kamil Osmanjan supervised the install of our kitchen. His guys were professional and skillful. Even the counter install people appreciated how perfectly level the cabinets were! The cabinet install took 3 days which included - uppers, lowers, island and Oven-Pantry wall units. They covered all the floors in my house before working and vacuumed each night before leaving. Even though we demoed the old kitchen ourselves, Kamil was still willing to fix some of the things we missed. He was very accommodating to our requests on the spot. For Example - he moved the gas line inside the wall so that it will not get in the way of my drawers (it helped that he is licensed). We also asked him to trim out the Pantry wall on the spot and he made the time to do it. We are very thankful to his expertise in kitchens. He gave us his number and always answered his phone. OVERALL: I will definitely hire them again for any remodel project in my house. They are a great team and know their skill to the core. We have learned so much going through this process and appreciate the Prime team for their work. PS - the vent hood cover is delayed by GE appliances, please imagine that it's covered!Posted on Google Ashley GoldTrustindex verifies that the original source of the review is Google. Prime Custom renovated my master bathroom and I am thrilled with the final result! It has become like an in-house spa. I always feel like I'm at a fancy hotel when I'm in my bathroom now which makes me so happy. The quality of the work is great and if ever I had an issue with something, all I had to do was ask and it was resolved without question. Mauricio and Blanca are very hard workers and I enjoyed working with them during this process. The tile installers were also very impressive and even came on the weekend so as not to delay. Kamil, the owner, even did some of the work himself! The crew did their best to keep everything clean and I appreciated that the floors leading from the front door upstairs to the master bath were all covered to prevent any carpet damage or mess. The whole process took longer than what was stated in the contract but with COVID delays I do not fault the company. They still finished the work in 20 working days. My project manager, Teagan, was a pleasure to work with. He was extremely polite and respectful. While we were waiting on one final piece of the bathroom to be delivered (tub), we self-installed a bidet attachment and accidentally dented the brand new tower cabinet with a wrench in the process (don't bring tools into your brand new bathroom!). The damage was on one drawer and even though the beautiful cabinetry comes with touch-up paint, we couldn't quite get it to look right. I showed Teagan and he took the drawer and got it repaired at no additional cost to us. You can't even tell that we dented it! I very much appreciated this service and it really shows that they care about their customers. I did feel I was a valued customer during the process. Not everything with the bathroom went smoothly. This is primarily attributed to the designer that was assigned my bathroom. She did not order things in a timely fashion, nor would she get back to me about things when she said she would. It was very frustrating and resulted in miscommunication to the team and things being ordered incorrectly or not ordered at all. However, this designer is no longer working at Prime. I don't hold this part of the experience against the rest of the team because they did all they could to remediate any issues the designer caused, and moving forward, there shouldn't be these issues. All in all, the bathroom looks amazing, I'm so pleased with the end result. A bathroom remodel like this is never inexpensive but Prime offered great value and service. I chose to use them over other design-build companies because they were most willing to help me try to be as close to my budget as possible and were transparent with pricing between labor and materials (as opposed to all the others who estimated an additional $10k+ and didn't itemize the labor/materials costs). Additionally, while they are more expensive than a non-licensed crew, to me paying extra for the licensing and people to organize the permitting and everything is worth it!Posted on Google Robert BessererTrustindex verifies that the original source of the review is Google. We were very pleased with the job that Prime Custom Kitchen and Bath did for our kitchen design and remodel. This was a major remodel and investment so we took our time and got several estimates and different designs. We decided to go with PCK&B because of the reviews and recommendations and we also got to know Kamil and Feliz pretty well during the process and felt comfortable with them both. We had 2 remodels done, first was the upstairs master closet we changed a his/hers closet into one big walk-in closet by taking walls down and changing the lighting. They did a nice job on that one. We also had hardwood floors installed in the entire upstairs bedrooms and hallways. Again nice job we we’re both pleased by the end result and the floors look great. The kitchen was a massive remodel. We took down 2 major walls separating family room/kitchen and dining room/kitchen and we made one giant great room that ran the entire width of the back of the house. The kitchen was a galley style kitchen with a massive island running down the center. We ended up doubling our storage and cabinet space from the old kitchen. We can’t say enough how much we love our new kitchen. It’s just a joy to cook in and we really like the Fabuwood cabinets so far. That was also a deciding factor for us because we didn’t care for the stocked cabinets at other companies that we worked with but we liked the Fabuwood look and feel. Our family and friends who have seen it can’t get over the difference and how beautiful the kitchen is and how it’s transformed our entire main floor of the house. Overall the job was excellent and I thought that both Teagan and Kamil were responsive to any concerns we had and addressed them right away. With a job this big there are bound to be some hiccups but they really did respond well to our few concerns.
