    New bathtub got damaged during construction. Was left unprotected for months while work was going on.
    Amit P.

    Do yourself a favor and look for someone else. We did a major renovation with GW and I could write a whole book about that unfortunate experience and everything that was done wrong there, including some shady practices of conducting business, but I would sum it up and say it was not good, to put it mildly. Feel free to send me a private message if you really want all the gory details, but trust me - you don't want to go through what we went through on this project. It might also be worth noting that the person listed as the owner of this company sold the company to new owners some time ago, so I am not sure all of the reviews reflect the current ownership. Matt (current owner) is a truly gifted sales person, but unfortunately, any resemblance between what he promises and what you will end up with, when the work is done, is entirely coincidental.

    Matt is fantastic!! He has done several home projects for us and all of them well. He is honest, friendly and professional. And he is very concerned and involved with helping our local neighbors!!

    I love my back yard

    I had GW construction come over to give me a price for my back yard . Michael, the project manager was very knowledgeable and nice and we decided to go with them . I really love my back yard now, GW did a fantastic job, Michael did give us an amazing customer service and we are definitely will do more project with them in the future. Thank you GW

    My wife and I highly recommend GW construction and our experience was wonderful from start to finish. We got several bids to add a 350 sq ft master suite (bedroom, bathroom, walk-in closet) to our home in Bay Park. After meeting with several contractors, we decided to go with Matt from GW. He was extremely communicative throughout the entire project via text, phone calls, or in person. Gary, the owner, came by often to ensure the work was up to his high standards. We passed every inspection the first time. The final product is absolutely fantastic, our house feels great, and we are very very happy to have gone with GW construction. The pictures do not do the work justice and we'd be happy to personally show anyone that would like a visual reference.

    Fantastic team at GW Construction! We were a bit nervous selecting a new contractor after a terrible experience with our previous one, but Matt and Jody made us immediately comfortable from the time they stepped into our house, and listened to our requirements and our concerns. Their advice and experience was also very valuable to us when having to make decisions across different options. Our project mostly consisted of windows replacement and expansion of our dining area with French Doors to a new patio, including built-in shelving and cabinets around the front window in our living room. We talked to them about a couple more projects as well, and Matt was very helpful when he broke down the quotes as we wanted to see them with the various build options we were considering. All along the process the best part with them, besides being very easy to get along with, was full transparency and clear communication, which is not always common based on our past experiences. The candor was mutual, and they were sure to be addressing our concerns extremely promptly. I cannot say enough great things about the team who did the work, in particular Gonzalo who had great attention to detail and who made sure we were happy with the results. Note that they also take very good care of the work areas and cleanliness is a priority. I will definitely recommend GW Construction to our friends and in our neighborhood. We have a couple more projects in mind which we already discussed with them, and I will not even think about selecting another contractor.

    Matt is amazing!! I wanted to put up a sunshade over my back patio and asked Matt to come by and give me a bid (no charge for consult!) He was 100% honest that he had never done this before but was totally willing to work with me. We had so much fun figuring it out and making it happen!! As you can see from the pictures, we were quite successful. Matt is a great human who is willing to help people in need. He is currently dedicating part of his day to help shop owners clean up after some recent destructive events. THANK YOU, MATT!

    Gary and Matt are marvelous!!! They are doing exactly what they promised and more! Since we have come to know them we have relaxed and are extremely happy with their work. They are doing more than what they were contracted to do and are proving that they are experts at their craft. We feel blessed that we know them and that they are doing our job. Thank you Gary and Matt, we will use your company for any future work we have planned. Job well done!!!

    Has anyone ever used the guarantee GW construction offers on their work?

    Gary sold the business, probably around 2019, so it's not really the same company. Matt is the new owner.

    Has anyone ever seen or meet the listed owner, Gary Mcculloch, ever speak with him? I have called their office many times and he is never there. I really think that the people that are running this company are using his name, contractors license and…

    I actually did speak with Gary and even met with him, very nice and pleasant man, he answered all my questions and addressed all of my concerns. hope this helps!!!

The crew arrived on time every day, kept the worksite clean (they did a full cleanup at the end of each day), and treated my property with respect throughout the project. The quality of the installation itself was top-notch--exactly what you want when you're investing in something as critical as your roof. A special callout to Dylon, the project manager. His communication was exceptional--clear, proactive, and consistent. He stayed directly involved throughout the job, which made a big difference in ensuring everything went smoothly. It's rare to see that level of hands-on management. They also handled the solar panel dismount and reinstall flawlessly, which is not a trivial task. Even though I'm now upgrading my system due to the NEM 3.0 transition, their work made that process seamless. Post-installation support has been just as impressive. They've continued to be responsive and helpful, especially coordinating around my new solar project--something many companies tend to disappear on after the job is done. Pricing was very reasonable for the level of quality and service provided. And as a bonus--no nonsense on the job site. Unlike some other crews I've seen in the neighborhood, these guys were professional the entire time. Bottom line: excellent workmanship, strong communication, fair pricing, and a team that clearly takes pride in what they do. Highly recommended.

    Warning !! This review may be lengthly however I promise You it will be worth your time to read if…read moreyou are in need of roofing replacement! So I developed a roof leak at our home and the existing roof was at least 25 years old so it was now time for roof replacement! I did my research and contacted the owner Troy whom was very thorough and informative during our conversation and he answered all of my concerns. The next step was to have my roof inspected, address any concerns and formulate an estimated cost for recommended repair. The estimator Dylon spent nearly 45 minutes performing a complete and thorough inspection. I have solar panels and gas lines mounted on our roof which complicated the roof replacement process. Good news is San Diego County Roofing (SDCR) partners with a great solar company and therefore de-activating the solar system, solar panel(s) removal, replacement and re-activation of the solar system is all taken care of through SDCR. Also SDCR warranties all work provided by their partnering solar company. I chose SDCR to replace my roof and what a great decision it was. I was updated and kept informed through each and every step of of the roof replacement process. I had some wood issues (rotting, worn out etc...) and the cost for the wood replacement was very reasonable. Tarps were laid out to cover our pool and artificial turf and after each day the residence was thoroughly cleaned of debris. Edgar the supervisor was always available whenever I had any questions or concerns. Also Dylon was always "Keeping tabs" with the progress and kept me informed of any issues and offered options when applicable. I felt very comfortable knowing that Dylon was always "on top" of things! Upon completion of the job, Juan invited me to view the new roof replacement and informed me of all that had been done and answered all of my questions and concerns. He even explained that my flat roof section of the garage had 2 sheets of "roofing" (know as "torch down") installed as compared to 1 sheet of roofing which most roofing companies provide, something I wouldn't have known. Everything was great and I was extremely satisfied EXCEPT one big problem! Apparently during the process of replacing my roof, a section of my newly installed artificial turf in the front of my house became damaged. I contacted Troy to discuss this big concern not knowing what to expect. After our discussion he instructed me to have the turf replaced and that I would be reimbursed for any and all cost. I had the artificial turf replaced at a cost of $2,200 and true to his word troy had a company check in the amount of $2,200 sent to my house within (1) week. So rest assured SDCR will give you phenomenal service. The company is professional, honest and transparent every step of the way from start to completion. This company has proved should something go wrong, they will make it "right". I highly recommend SDCR and I'm so glad I made the right choice! You should make the right choice too!

We simply…read morecan't say enough great things to reflect the true gratitude we have for Liza and her team at Coast Remodeling Services. They really are the best at what they do -- and they do soooo much! There should be absolutely no doubt in your decision to tackle any project with them, big or small. Just go ahead and book them now and save yourself the time and energy of searching. They truly understand how important your home is to you, inside and out, so they won't disappoint. Maybe most importantly, if any random issue does arise (which it always does with a big project), they will be on top of it immediately! We worked with CRS on both a full roof replacement and a MAJOR bathroom remodel. We were lucky enough to be referred to Liza by a trusted local contractor friend for our roof repair. We got multiple quotes from roofing companies, as it was a big expense for us, but no one understood or communicated better than Liza. Not only did she offer a better product and solution, she also came in more affordable than all the other bids! Her team did such an amazing job on our roof that we reached out to Liza again a few years later for our full bathroom remodel. Oh man -- there's really no way to put into words how much of a project this bathroom was to take on. We ripped the old bathroom down to the studs, expanded its footprint, and fully rebuilt it into a glorious, resort spa-style sanctuary. Major vibe and an inconceivable space upgrade! Liza and her lead builder worked side by side with me daily throughout the entire process. From planning to purchasing, demo to details, problems to solutions -- they nailed it. We inevitably encountered some "fun" issues like improper support beams and suspect wiring, but they always pivoted and solved each problem quickly and thoroughly. The team's positive attitude and good spirits were also a notable and welcome part of the experience. This isn't my first major project, and let's face it -- you don't often get to work with true pros who are both really good at what they do and genuinely good, happy people. They are! It's been a few months since we finished the project, so I feel bad that I didn't get this review up sooner. We just couldn't seem to put everything they accomplished for us and our home into a concise synopsis. We wanted to gush about every little thing, but in the end, all you really need to know is that we were 100% satisfied, and you should feel 100% confident teaming up with CRS to successfully bring your next project and vision to life. Seriously -- feel free to message me with any specific questions about our experience with the roof and/or the bathroom remodel!

    Review Update: After…read moremy initial review, Eric (the sales rep) and Matt (the owner) of Sunline personally reached out to me and was apologetic about the situation. They sent Travis out promptly, who is their electrician where he found that the issue was resolved by replacing a faulty 40-amp breaker that was intermittently providing the necessary voltage, even though measurements initially appear correct. While the breaker issue caused real inconvenience and unexpected costs on my end, the owner was responsive and showed willingness to smooth things over to work toward a resolution. I also want to highlight that the panel upgrade and solar/battery installation itself was clean and well done. The workmanship that Eddie, Manny, Christian and Jamie performed had overall met my expectations, and once the issue was identified, Sunline did step in to correct it. No project is perfect, but how a company responds when problems arise matters a lot. In this case, Sunline's owner and Eric was engaged, responsive, and made a sincere effort to make things right. As an engineer, and after witnessing the symptoms and corrective actions firsthand, I believe the breaker issue was likely a manufacturing defect, and it was unfortunate that it occurred during the holidays. That said, based on how Sunline handled the situation, the overall quality of their work, and the value they offer, I would recommend them and plan to continue using them for future needs.

He explained everything in a way I could understand, and I never felt rushed as I was talking with him. He even helped me coordinate/communicate with the solar group to ensure all the timing worked out, and to ensure the solar group didn't pierce/damage the new roof upon reinstall.
