#593 of 678 scored in California by Solar.com Installer Score

How does California Coast Builders compare where you live? Rankings are local; an installer that leads one city can trail in the next. See how they rank in your city →

Why this differs from star ratings: most five-star reviews say “great company” and stop, and star averages reward that. These category scores only count reviews with concrete evidence, weighted by recency and the reviewer’s track record. A company can hold a strong star average while specific categories score lower; that gap is usually where the real story is. Categories with more complaints than praise are the questions worth asking any bidder, not necessarily dealbreakers.

Where California Coast Builders builds

County-by-county activity from CPUC records through May 2026.

What this data covers: *Counts on this page, including the totals up top, come from investor-owned-utility interconnection records (SCE, SDG&E, PG&E). Work in municipal-utility territory, such as LADWP or city utilities, and outside California does not appear here, so this company's true totals are higher than shown. Unlike the county rankings, this profile also shows counties below the 250-install ranking floor.

California Coast Builders reviews: what customers say

An independent synthesis of published customer feedback across Google and Yelp, updated September 28, 2026. Green marks praise, amber mixed experiences, red complaints.

Sales & proposal integrity

Sales Integrity5.1/10

Reviewers are split on sales and proposal handling. Some describe clear, detailed proposals and knowledgeable upfront guidance, while a larger share report pressure, unclear expectations, or concerns about how the deal was presented.Solar.com's composite of published customer feedback, not a customer quote

Pressure and shifting terms. Other reviewers describe sales interactions as uncomfortable or overly aggressive, including concerns about how discounts, written quotes, or contract terms were handled. The complaint pattern centers on proposal clarity and whether the initial terms matched later expectations. Representative review excerpt: "When I held them to the original written quote, they wrote the contract giving themselves an out if they couldn't make enough money."

Good work, but sales concerns remain. A few positive reviews mention satisfactory completed projects, but those comments do not outweigh the recurring complaints about the sales process. Overall, this category reads mixed with a negative lean. Representative review excerpt: "I called this company and a gentleman named Tony came out and was very very knowledgable Not only did they do good work and work cleanly before I signed the..."

Clear proposals. Some reviewers say the company provided fair, transparent proposals and addressed the full scope of work. These reviews also describe knowledgeable sales guidance before signing. Representative review excerpt: "You can expect a fair and transparent proposal that addresses the entirety of a project."

Price & financing transparency

Price Transparency6.1/10

Feedback on pricing and financing is mixed. A small number of reviewers describe helpful guidance, but more complaints mention costs changing, deposit or paperwork issues, and uncertainty around rebate timing or refunds.Solar.com's composite of published customer feedback, not a customer quote

Higher-than-expected costs. Several reviewers report that the job cost more than the original quote or that pricing did not stay aligned with what they expected. These comments suggest concerns about final cost clarity. Representative review excerpt: "He pointed out that the job would cost more then their quote, so I pointed out that maybe they shouldn't make offers they weren't prepared to honor."

Paperwork and rebate timing. Other complaints involve paperwork, refund follow-through, and timing around a state refund. The pattern is less about one-time billing mistakes and more about whether customers felt the financial process was clearly managed. Representative review excerpt: "Not to mention they were supposed to do all the necessary paperwork for the state refund which for me was $1200 which i have never received."

Helpful upfront guidance. One reviewer describes a helpful conversation about project needs and says the estimate process felt manageable. This is the main positive signal in an otherwise limited set of price-related reviews. Representative review excerpt: "Rob was very helpful and understood what I needed for my room addition, patio cover and other various projects."

Communication & coordination

Communication5.4/10

Reviewers give mixed feedback on communication and project coordination. Some report consistent updates and smooth coordination across larger projects, while others say calls and emails went unanswered or that they had difficulty getting issues addressed.Solar.com's composite of published customer feedback, not a customer quote

No response to follow-up. Several complaints describe unreturned emails or calls and frustration getting a response after the project started. The recurring concern is not just slow replies, but a lack of follow-through. Representative review excerpt: "And has not responded to my emails or calls since."

Project communication varies. Other positive reviews describe a transparent proposal process and smooth coordination on broader jobs, but the category still has a noticeable complaint pattern. Overall, communication appears uneven across reviewers. Representative review excerpt: "You can expect a fair and transparent proposal that addresses the entirety of a project."

Frequent updates. A few reviewers say they received constant communication from start to finish and felt well informed during the project. These reviews point to strong hands-on coordination when the process goes well. Representative review excerpt: "He was in constant communication throughout all of my projects from start to finish."

Timeline reliability

Timeline Reliability6.7/10

Timeline feedback is slightly positive overall. Several reviewers say the company showed up on time, completed work as scheduled, and handled permits or installation steps cleanly, but some others describe reschedules or no-shows.Solar.com's composite of published customer feedback, not a customer quote

On-schedule completion. Positive reviews often mention crews arriving when expected and finishing on time or earlier. Some also note that permits and design steps were handled as part of the process. Representative review excerpt: "On the basics, they arrive when they say they are going to arrive, do what they say they're going to do and finish the job on schedule or earlier and..."

Permit and installation timing. A number of reviewers say the project moved on schedule and that installation was completed right on time. These comments make timing one of the stronger areas in the review set. Representative review excerpt: "They took care of all permits, designs, and installed right on time."

Reschedules and missed calls. Complaints focus on delays, rescheduling requests, or lack of a timely phone call when plans changed. The issue is consistency rather than a single isolated delay. Representative review excerpt: "They again asked me to reschedule, but at this point I felt the business was not reliable and not someone I would choose to spend my hard earned money on."

Workmanship & site care

Workmanship7.7/10

Workmanship and site care are the strongest-reviewed parts of the profile. Most reviewers describe professional crews, clean installs, and solid results, with only one clear complaint about a later structural issue.Solar.com's composite of published customer feedback, not a customer quote

Clean, professional crews. Multiple reviewers say the work crews were friendly, considerate, and cleaned up after themselves each day. These comments suggest strong site care during active construction. Representative review excerpt: "The work crews were friendly, considerate and cleaned up the site at the end of everyday."

Solid project execution. Several reviews describe successful additions or other major projects and say they would use the company again. The workmanship feedback is broadly favorable and more consistent than most other categories. Representative review excerpt: "After looking at many contractors, we contracted with Rob at California Coast Builders for my 1100 square foot addition in Bay Park that included foundation, plumbing, electrical, doors & windows..."

One durability complaint. There is one complaint about a wall starting to come apart after installation. That issue is notable, but it is isolated relative to the volume of positive workmanship remarks. Representative review excerpt: "The wall that they installed for me is starting to come apart."

Long-term support & performance

Long-Term Support5.0/10

Post-install support and system performance are a weaker area in the reviews. Some customers report lower bills or good results after completion, but others say follow-up support was limited, monitoring issues were not addressed, or system performance did not meet expectations.Solar.com's composite of published customer feedback, not a customer quote

Positive results after completion. Some reviewers report lower energy bills or say they were pleased with how the finished work performed over time. These comments suggest the company can deliver good results after the project wraps up. Representative review excerpt: "We've even seen a lower energy bill due to not having to run the AC on hot days since the new windows are keeping the heat out."

Monitoring and follow-up concerns. Other reviewers say they were not notified when a system went offline or could not get calls returned about monitoring concerns. The pattern points to weak post-install responsiveness in some cases. Representative review excerpt: "Never reached out to notify me my system was offline."

Performance issues after install. A few complaints describe ongoing frustration with how the system was set up or serviced after completion. This category has enough negative feedback to keep it clearly mixed. Representative review excerpt: "2 years later im still fighting with them because they did not figure my system right and im short almost $1000 a year to SDG&E just for electricity."

Bottom line: California Coast Builders receives its strongest marks for workmanship and site care, while sales clarity, communication, and post-install support draw more mixed feedback. Timeline reliability is somewhat positive, but several reviewers report issues with pricing transparency, follow-up, or keeping customers informed after the project starts.

Important context: this chart shows investor-owned-utility records only. Companies that shift work toward municipal-utility territory (LADWP and city power departments) or other states will show declining bars here even while building steadily elsewhere, and 2025-26 records also lag real installation dates. Treat this as a partial window, not the company's full trajectory.

How we built this data

Methodology: Counts are residential PV interconnections in investor-owned-utility territory (PG&E, SCE, SDG&E) per CPUC Rule 21 public records through May 2026. Postal and name variants are merged. Municipal utility territory such as LADWP, Glendale, Pasadena, Burbank, Anaheim, and Riverside Public Utilities is not included in those CPUC counts. Counts show recorded installations, not quality ratings. Reported costs are self-reported on owned-system interconnections. No installer can pay for placement.

Who we are: Solar.com is a solar marketplace — we connect homeowners with installers and earn a fee when projects move forward. These rankings and scores are computed from public installation records and published customer reviews. No installer can pay for placement, and no installer — including those we work with — can pay to change a score.
