CI Services recently re-roofed my house. They were very professional in all aspects of the job. The work was completed on schedule.

Rooftek was an awesome partner for my roofing project. My home needed a roof replacement, and they…read moretook care of it in a timely manner. David and his team did an amazing job throughout the whole job, and gave me a very fair price for the work that needed to be done. If I ever have any other roof issues, I will contact them directly. My roof turned out great!

Unfortunately, my experience with this company was frustrating due to poor communication and lack…read moreof follow through from the technician, Arturo. When Arturo came out to inspect the roof, he provided a verbal quote, but no written estimate was ever sent. Since my husband and I were in the process of making decisions based on contractor bids, I later reached out and specifically asked if a written quote could be provided. After waiting without receiving anything, I followed up with Arturo by text and was told that he would send the quote later that day. Four days passed, and I still did not receive the written estimate or any update. I sent another follow-up message and received no response at all. The only positive part of my experience was communicating with their staff, Abigail. The person responding to my texts, who I believe was Abigail, was responsive and helpful whenever I reached out to the company's main number. Unfortunately, despite her responsiveness, I still had difficulty getting the information I needed from the technician assigned to my project. I understand that delays can happen, but timely communication and following through on commitments are important. Based on my experience, I was disappointed by the lack of responsiveness and would encourage the company to improve communication between their technicians and potential customers.

Top flight work! My deck needed resealing due to maintenance. I also had a leak. Two other…read morecontractors gave me quotes for over $10k without doing any testing. Jose came through said he wanted to do a water test for a nominal fee that would be applied to the total work. He did the test. The test revealed that the leak was actually come from an outdoor outlet instead of the deck. In other words, if I had used any of the other contractors I would have paid over $10K and the leak would not have been repaired. I got the outlet sealed and the deck resealed and Westcoast's work was immaculate. They completed it punctually and even came back to put back all the furniture. Thank you! I highly recommend this honest, competent contractor!

Jose was quick to respond and come out for an initial estimate. After receiving a few competitive bids, we felt most comfortable with Jose's team and moved forward. When the team began work by removing some of the balcony planks, they realized that there would be a more efficient fix that would provide the same leak protection at a lower price. I don't know many companies that would be that transparent and honest. Jose and his team clearly care enough to do the very best job at a reasonable cost. Jose is the best, and he hires the best people to work with him. Highly recommend!

Professional Drainage Experts were awesome to work with! Foster was on time for our initial…read moreproperty assessment and showed us two options that worked within our budget. He walked around the property and broke down the different drainage solutions while answering our questions. He made it easy for us to understand each option. We did get quotes from other vendors but ultimately chose Professional Drainage Experts based on the customer service and willingness to work to find a solution for our property that was in budget. We were able to get a full system added to the property in 3.5 days. Julio and his team were great! They were promptly on time each morning. Cleaned up after themselves. Even hosed down the driveway, stucco, and walkways afterwards. After everything was installed, Julio walked us around the property and explained all of the elements of our new system. For what feels like a draining home project as a first time home buyer, Foster and Julio made the process feel less daunting and stressful. Highly recommend. 10/10

Their estimator, Foster, was alongside me throughout the job process with any questions or concerns that I had. Before the job even began, he ran through several scenarios with me and was very patient. He understood my objectives both as they related to aesthetics and my pocketbook. In the end, we came up with a plan that was viable and as aesthetically pleasing as could be managed given the situation. Once the job began, the primary person of contact shifted to Julio, one of their project managers. He was on property every day supervising and working alongside his crew. The crew was very polite, hard-working and friendly. They were very well supported by Julio. This may seem like a given, but often it is not so it did stand out to me. Once all of the work was done, Julio gave me a final walk-through, showing me how the various components function and made certain that I did not have any lingering questions. I think there were two follow up visits after the work was completed in order to accomplish this. There was no point along the way where I felt like they were taking shortcuts, using materials that were inferior quality, or anything of that nature. Their concrete cuts were incredible, and I have seen some really bad cuts in my past. And they did a beautiful job with brick work, including redesigning some curved areas of brick that needed to be removed during the job. Veronica in the office was very helpful as well. All in all, having my work done by Professional Drainage Experts was a very positive experience and I give a hearty recommendation to them!

I was pleasantly surprised to receive a response from Brandon on a weekend, when I was extremely frustrated with a persistent leak in my home. I've spent a significant amount of money on repairs, and the leak continues to be a problem. Jack was sent by Brandon, and I could sense his expertise from the way he asked questions and thoroughly examined the potential entry points for water. After hearing about the previous company's unsuccessful attempts to repair the leak, Jack flew a drone over my roof to check for any open seams on the copper roof dome. He then meticulously examined the roof with a toothpick and asked me to wait for the next rainstorm. He instructed me to send him videos of where the water was coming from. Jack also asked me to check the areas where the drywall had been opened up underneath the copper roof during the previous repairs to see if they had gotten wet. By process of elimination, he determined that the roof leak had been repaired, but the water now coming down from the window frame was coming from the gutter nearby. Immediately, he provided me with the contact information of the gentleman he works with, and I'm hopeful that the issue will be resolved soon. I'm grateful to encounter honest and reliable individuals in this day and age.
