Very disappointed. We wanted Solar, but the sales guy didn't seem to know much about that and steered us toward window replacement instead. Actually not a bad idea. We liked the salesperson and decided to use the company even though they were not the cheapest quote. The first time around they made mistakes on the contract so had to come back again to re-do. That's ok, everyone makes mistakes sometimes. Next, we had to wait for the guy to come over and take more accurate measurements. We have 45 windows so we expected that to take the guy a long time. He walked in, looked at one window, and said no. They have quoted you wrong and walked out again. Super rude. So we waited for them to come out again. Got things sorted we thought the 3rd time. The cost did not go up as the sales guy said it was his mistake. Waited another week to get the appointment for the guy to come out and do accurate measures only to get a phone call saying that they had taken another look at the quote and it was completely wrong and they said the cost would be almost double! I laughed at the guy and said "So you really don't want this job do you?". I was annoyed that they had wasted so much time and we wanted to get the windows replaced ASAP with winter on the way. read more

Did not show for scheduled appointment sends a bad message on dependability I'm sorry but that isn't a good message to send seeing as how they changed the original appointment to. Today read more

Very pleased. Backyard install of decomp granite. Hauled away broken concrete, pile of tree limbs and 14 extra large bags of bush/tree debris & last years xmas tree. In the front yard a 14'x37" high block wall, poured a cement patio with a wrap around 6' wide walkway to the backyard. What you get with COBEX is some of the hardest working, fast, efficient and polite crews I have ever seen. The Project Manager Dmitriy ensures he keeps you apprised of when the different crews will be arriving and their tasking. I was impressed with how Dmitriy offered sound alternative design options for consideration. So now, am thinking about a wish list of projects: a good neighbor 6 ft tall brick wall between our front patios, new flooring, replacing the patio door and exterior house paint job with TSR cooling type paint. I will hire them again and whole heartily recommend COBEX. They will not let you down-it is against their business ethics. read more

The final phase of our job has now been completed - the solar panel/system is up and running. Frank and Adrian were so great to work with! If they promised to be here for something, they never failed to show up. The installation was very professional and every detail was taken care including the painting of the conduit leading to the box and meter to match the siding. They interfaced with SMUD efficiently and kept us informed of their responses. I cannot praise them enough. Also want to thank David Leal, who never failed to respond to my questions about the financing. Keep up the excellent work Cobex. read more

Where do I start? They are a prime example of why I loathe dealing with contractors. I met them at the Roseville Home Show and we scheduled an appt for a few weeks later (good sign that they were booked through those dates). It allowed me time to research the company and read the reviews. Julian arrived on time and was courtesy and professional. He provide me a quote, I signed the contract, gave the deposit,and became excited about my roof and siding to be done. Here it comes - the day before they started the work,Sergey and another gentleman came out, ripped off some of my trim around my house and they were poking holes everywhere. Low and behold, they DOUBLED the price!!! It went from $25k to $50k. I honestly thought I was on canid camera. Wait - There's more. I canceled the siding portion of the contract because I don't have an extra $25k laying around. They left my house exposed from where they removed the trim, and I discovered they removed a large portion of my siding and just left it! I have a zero lot line and it was my neighbors side of the yard, so I didn't even know about it. She was trying to sell her home and I was appalled. I called Sergey and sent him the picture you see below and he said, "oh sorry". They did a phenomenal job on the roof; however, I had to call many times. They told me it was going to be done on a Sat and I came home from a trip to find trash in the yard and it not complete. They left it like that all weekend - so embarrassing! Once again, the response was , "sorry". After an entire week, it was finally finished. The only reason I gave them any stars was the quality of the work and the pleasantries of the workers. They are a contracting company as to why I hate being a single female, to take advantage of. read more

I did a lot of research on getting some remodeling done on a home I just purchased. I'm glad I did, Cobex went above and beyond my expectations. A new roof, a new kitchen remodel and a new back door entry. Also had some electrical issues that they were happy to address as well. Would certainly recommend this company who wants a big or small job done, they are all perfectionists. Thank you once again for the wonderful service and an absolutely wonderful job that you have done on my home read more

Best decision ever! New roof from Cobex, Can't emphasis on the overall great experience we had from start to finish. Vaz was really great went over everything and was easy to reach for any questions we had along the way. Don't take my word for it take their actions for it! Thanks Cobex read more

What a nice company to work with. I had a horrible leak, and the water was running down the center of my entryway, and coming right out the light fixture above my front door. I called, Cobex, and on the first answer they set me up with an appointment to do an inspection. The gentleman found the leak, went up into my attic and took photos of the areas that showed where the water was coming from and also a couple of other obvious leaks. He gave me a quote, which was reasonable, even offering to work with me, and set up the repair. We were in the middle of rainstorms, so it took over a week to begin work, but once they came out, the work was completed in one day. That included removing my old broken solar panels that were just an eyesore. Great company to do business with, and I recommend them for your future job. read more

Would absolutely recommend Corbex for window installation. They were quick, efficient, courteous and very responsive.

i have been looking for roofers and scheduled an appointment with Cobex and a gentleman named Vaz came out...although we are still in the process of choosing a roofer i was very impressed with Vaz, clean, wore mask, was up on roof, came down ready to talk numbers. Most of the roofers that came out didn't even go on the roof and quoted really super high ridiculous numbers but Vaz was in our ballpark at least...so really great salesman very polite and didn't go on and on about products basically only went over what we didn't know...and as a woman he spoke directly to me. So thanks Vaz your the type of salesman people love to deal with. read more

From start to finish, Cobex did an amazing job Trevor Sprung was my first interaction, he was very knowledgeable in the product and fair with pricing and great communication. Max settings up the installation and coming out and checking to make sure everything was ready and after the job checking customer satisfaction. The installer was very organized, professional and beautiful work. I can't wait to have more work done to my home . Thank guys for all the hard work and beautiful job on my sliding glass door. read more

We recently gave cover to do our hardy siding and all new windows on our new home. Sergy won us over with his charm and we signed a $92k contract. Max the person who ordered the windows ordered several incorrectly and forgot one window all together. The siding installer was the best part of this experience, just little things like not filling in the nails holes for paint, caulking in some areas not good just some small things. The work with AnLin windows and that is another substandard part of this experience. The window install was not good, damaged wood floors, some were left not plum therefore would not lock and handles have to be reorder due to damage during install. We all work very hard for the money we have and our homes is our biggest investment therefore, please be very careful when using this company. We tried to get a local small business a change and it cost us more money and grief that we are still dealing with. And to finalize our experience with Cobex we are having a Tesla Roof put on and Tesla reached out to Cobex to have them come out and ask them the best way to deal with a couple small corners where the roof would need the new siding they installed cut. Cobex refused to help them and gave them a horrible story about me. I am a business owner whom works very hard and the original experience we had with Cobex was stressful and not pleasant. Max missed an entire window in the order and ordered 5 others incorrectly. I could go on and on, however, I am sure people looking to get an honest review of companies prior to hiring them will get the picture. Our Tesla project will move forward, however, the unprofessionalism just keeps getting worse. Please use caution when dealing with Cobex. read more

Cobex installed quartz countertops in our kitchen, bar and bathroom areas. They set all the sinks as well. Their work is absolutely flawless. Dima, the project manager, is tops in professionalism and exceeding our expectations. The installer, Alex, was extremely thorough and professional. His work is flawless and he thoroughly cleaned up the site. Everyone I dealt with was personable and fully explained the process to me. Dima always kept us updated on arrival days and times. I have referred them to two other friends looking for kitchen remodels. Thank you Cobex Construction read more

I was going back and forth with the owner and scheduled an appointment for Tuesday (today) at 1:30. He was very accommodating since it was originally scheduled for 1pm, but since I had another meeting scheduled till 1, he changed the time to 1:30. 1:30 came around today and nothing, no call, no message. Very disappointed, as I was looking forward to working with more than just a painter but a contractor, as there are several jobs I will be needing in my new home. *update 5/8 After posting my original review, I want to update to a 4-star as there was a mix up in the appointment dates/times. I am real big on customer service and appreciate the call back. I have rescheduled to a later date and can hopefully update to a 5-star after meeting with them. read more

Cobex was did a great job replacing my roof. I had a number of companies come out to inspect the roof to give a quote and Cobex was the most through and well explained quote. Price was not the lowest bid but they saw and included many things other companies didn't even mention in their inspection and quote. read more

I give them 1 star for showing up! I expected a contractor and I got a young salesman who wanted to be a wiseguy. He gave me an estimate of 20 to 30 thousand dollars from my backyard in 2 min? Yea, imagine that. He acted like he knew nothing about our house, then when I told him it was not a huge job he had all the specs of house memorized? Hmmm? Then he said $6.25 per sq ft is minimum charge and that does not include any dryrot. I said why didnt you tell me over phone or email if you already knew price? Then he said $200 a panel to remove solar panels. I said theres 19 panels! That is 4 grand! He said ok, $125 per panel. He manged to do all that in the 3 minutes he was there. Did I mention the roof was for my mom who is 77 years old? Just to reiterate. He never got closer to 30 feet from roof or eves. When I told him I am sorry I wasted your time, he said do you want me to tell them you cancelled appt. I said I didnt cancel appt. You dont want to work! Period, end of story! Bottom line! Do not go with this company for roof! CALL A REPUTABLE ROOFER! read more

I regret hiring Cobex to install a new roof on my house. They took five months to begin work and took twice as long as expected to complete. We asked the sales crew for custom skylights and to repair dry rot on the architectural details of the house. None of these details were passed to the construction crew and during construction, we were told the custom skylights would not be covered under warranty. It also became apparent that they did not have the expertise to handle the carpentry work for the dry rot repair. I had to manage the project daily to direct the repair work and point out corrections. In the end, we didn't get the skylights we agreed to and the dry rot repair and detail work was subpar. They missed areas of dry rot and used inferior wood. Also, Cobex did not tarp the roof before a predicted rain storm and damage was done to the interior ceiling, walls, furniture and carpet. Five other homes they were working on were also affected. I hired another contractor and did work myself to make repairs they missed since I did not trust Cobex's workmanship. We were given a discount but that did not cover the cost of additional repairs and rainwater damage. read more

We had a roof done, recently in Grizzly Flats. They did great. Dave is a good salesman and knows his stuff. What I like about him is he listens to what we wanted. While other companies didn't show up for work his people did. On time and were very professional. The project manager, Viktor, very nice and professional. They had the roof off in one day. The install took 5 I was concern that they worked under light until 9pm. They needed a few extra workers. We had two to do the install. I guess the others didn't like the long drive. We knew there would be issues with the house, so I didn't mind the increase in cost as the problems were found and fixed to code. That whole house surprises me that it passed code. The big question is would I "hirer them again for other jobs?". The answer is yes They charge a bit more then other companies (estimate 5k) but the show up, do the work and they work hard. It is under warrantee and I have no doubt if any issues they will be there. The only complaint I would have is they had two guys worked fast and hard. And made mistakes, Which they fixed and did great. I would tell the managers to not push so hard as in the long run, it cost more time and money. It would have been better to stop working when the sun goes down and take that extra day. Just my opinion Yes I plan to have them do my driveway next summer. read more

Unfortunately my home had a partial flat roof that leaked. But we are grateful that we found Cobex out of several other roofing companies that had quality material, reasonable pricing and excellent customer experiences. Selecting Cobex made a difference in this project shared some pictures of their work. We would definitely recommend them not only for roofing, gutters but also lattice work as well. Sergey did an excellent job at project managing this project. Thank you for your services read more

I had new retaining walls installed and COBEX did an outstanding job. They made sure everything was done correctly and actually did a little more work than what was quoted. No price adjustment was needed and the quality of the work was very professional. It has been 2 years since their work was accomplished and the retaining walls and all their work still look like new. read more

Victor from Cobex came out and gave me a bid and of the four bids his was $1000 more. When he followed up, he drilled me for why I went with another party. I let him know that Cobex was out of the ballpark. He then became rude and offensive, telling me I was receiving substandard work and quality is not cheap. read more

This was a project started and completed the end of 2018. I did not rate them on Yelp at the time. I am in the Rescue/Shingle Springs area and was having a very difficult time finding a contractor here in the foothills that would even give me a quote. Cobex was a lifesaver! The Cobex Construction Group experience was great. Dave Palmer kept me informed. Although we were scheduled to start our project in January, they were able to move it up the first part of December. This was a lifesaver for us, as we had a houseful coming for the holidays. They successfully and professionally finished a week before my guests started arriving. Alex and his crew were great. He discussed with me what they were doing and when they expected to finish. Very pleased with their work! read more

A tree feel on our house in Pollock Pines. I contacted 7 roofing companies and only Cobex would take a look. There is no driveway and it made the work that much tougher. They had to repair 5 trusses and we had the whole roof done. Great job and looks beautiful!! read more

It started with a garage wall my son backed into. Also the fence connected to the wall. Impressed. Went on to the roof. Fantastic. Then the paint. Beautiful.

This company sent a lead generator door to door looking for households who needed a construction project done. They came for an estimate on a large project I needed done. They NEVER got back to me with an estimate. They never called, never followed up, nothing. I hired a much more professional and reputable company to do the job. So disappointed.Not impressed. About a year later, they called me and said they'd found my lead in their system. I told them no thanks. But now of course they don't remember anything about it. read more

First all I seldom give 5 stars to anyone unless they are really exceptional excellent in all perspectives. 4 stars from me need to be excellent in products, service and value. We used Cobex to replace all windows in my house this week, a complicated job with 30-40 windows big, small, different shape first floor second floor all kinds. The job was done beautifully and we are happy with the final result. As project manager Max did a good in recommending the right products for us based on various window location in the house. They show up as scheduled and finish as promised. I do want to point out that they did not put my furniture back as they were after they finish the job. Otherwise, I will consider giving Cobex 5 stars, because the window quality and installation services are really excellent. I recommend Cobex. read more

I could not be happier with this company. They were prompt every day on the job and did a nice job cleaning up afterwards. We had dry rot issues that needed to be addressed, and they came over and gave me a an estimate that was very fair.

Without a doubt, I can recommended this company ... read more

I found them at the Sacramento Home and Garden show and scheduled a quote and installation of a sidewalk to my sideyard. The work crew had a whole different drawing from the one the supervisor made during our meeting. I asked for a diagonal sidewalk that did not touch the house and would leave me with a triangular enclosed planting area.They instead installed a 90-degree walk that left me no planting area, but also buried my French drain downspouts. I called multiple times over several weeks and had a home appointment with the supervisor to show them the errors. The supervisor blamed the employees and said he would make it right, but never came back to fix it. read more
