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

How does Dura-Foam 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 Dura-Foam 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.

Dura-Foam 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 Integrity7.2/10

Reviewers are generally positive about the sales and estimating process, describing clear assessments, honest guidance, and proposals that matched the work delivered. A smaller set of reviews reports issues around scope clarity, panel assessment, and added costs or code-related expectations.Solar.com's composite of published customer feedback, not a customer quote

Honest, low-pressure estimates. Reviewers say the sales process could feel straightforward and non-pushy, with some describing honest assessments and estimates that helped them feel confident moving forward. Representative review excerpt: "Ask for Anthony to perform your assessment & estimate- Anthony is a master at this, plus he is an honest man!"

Useful guidance on roof condition. Some reviewers report that the team gave practical feedback about roof or system condition rather than pushing an unnecessary replacement. Representative review excerpt: "My solar panel inverter threw an error code and out of all the solar companies I talked to, Durafoam was the only company that didn't try to sell me a..."

Scope and quote surprises. A minority of reviewers describe problems with proposal detail or follow-up costs, including limited upfront assessment and extra charges tied to work scope or code-related fixes. Representative review excerpt: "These guys came out once, bashed our contractor's workmanship, and said they could replace all of the new flashing so it met "their standards," for an additional cost of several..."

Price & financing transparency

Price Transparency5.8/10

Feedback on pricing and financing is mixed and leans cautious.Solar.com's composite of published customer feedback, not a customer quote

Fair and Pricing pricing. Reviewers describe a recurring pattern in this area. Representative review excerpt: "During the initial install, they were great to work with, showed up on time, and did the work they quoted, and kept the price they promised."

Reasonable value for complex work. Some customers say the offer felt reasonable for the complexity of the roof or project, and that the work was worth the price paid. Representative review excerpt: "Great service, with a competitive reasonable price for my complex roof that has lots of water pipes, AC lines, electrical conduit lines, 17 large solar panels and 8 skylights with..."

Refunds and added-cost concerns. Other reviewers report problems with overpayments, refund follow-through, and costs that were not fully clear upfront, including situations where extra work or timing issues affected the final bill. Representative review excerpt: "Communications resulted in a promise by DF to refund the $200+ overpayment, but we never received a check."

Communication & coordination

Communication6.5/10

Reviewers often praise responsive office staff and helpful coordination once projects are underway. At the same time, a notable share of reviews describes unanswered estimate requests, missed expectations about who was handling the job, and communication gaps during scheduling or follow-up.Solar.com's composite of published customer feedback, not a customer quote

Helpful office coordination. Reviewers describe staff members who were informative and helpful when answering questions or working through project details. Representative review excerpt: "Wednesday: Had a very informative discussion with Paul in the office re: my two minor drain leaks."

Good communication during projects. Some customers say the team kept them updated and maintained a good attitude through the process, which helped the project feel organized. Representative review excerpt: "In the end, the Dura-foam team completed our project on time, with great communication and attitude throughout the entire process and with a great result."

Missed replies and handoff gaps. Complaint-focused reviews mention unanswered estimate requests, unclear ownership between teams, and follow-up problems such as promised updates or refunds not arriving as expected. Representative review excerpt: "They never answered my two requests for estimates."

Timeline reliability

Timeline Reliability6.8/10

Timeline feedback is mostly positive, with many reviewers saying work finished on time or stayed on track despite weather or coordination challenges. The main complaints involve scheduling uncertainty, last-minute changes, and occasional no-show or rescheduling frustrations.Solar.com's composite of published customer feedback, not a customer quote

On-time completion. Several reviewers say the project finished on schedule and that the company handled weather-related delays without losing momentum. Representative review excerpt: "In the end, the Dura-foam team completed our project on time, with great communication and attitude throughout the entire process and with a great result."

Helpful coordination under pressure. Some customers report that office staff helped manage logistics and contractor timing, especially when permits or inspections were part of the process. Representative review excerpt: "Furthermore, Anthony, from the operations department, provided valuable assistance in resolving logistical challenges as we were trying to get a new electrical panel installed, and inspected by the building dept..."

Scheduling uncertainty. Other reviewers describe last-minute calls, repeated rescheduling, or arriving for a planned appointment only to find the visit did not happen as expected. Representative review excerpt: "Last minute including day before calls to schedule workers."

Workmanship & site care

Workmanship8.1/10

This is one of the strongest areas in the review set. Reviewers frequently praise the quality of the roofing and solar work, describe crews as professional and efficient, and say cleanup was handled well, though a smaller number mention site mess, damage, or repair disputes.Solar.com's composite of published customer feedback, not a customer quote

Professional, clean installs. Many reviewers describe the crew as professional, quick, and clean, with little mess left behind around the home or panels. Representative review excerpt: "Looks professional, quick and clean."

Quality work across projects. Some customers note repeat work over time, including roof, solar, and maintenance jobs, and say the results looked solid and professional. Representative review excerpt: "Durafoam did our foam roof, then our solar and now a maintenance cleaning."

Cleanup or damage complaints. A smaller set of reviews reports issues such as muddy runoff, roof texture changes, or damage that reviewers say required follow-up repairs. Representative review excerpt: "I think it's ridiculous that they want to charge me to fix their work-never mind the fact that their workmanship damaged my drywall."

Long-term support & performance

Long-Term Support7.6/10

Long-term performance reviews are mostly positive, with many customers reporting lower utility bills, improved comfort, and systems that continued working well after installation or recoating. Still, some reviews describe post-install service concerns, including repair follow-through and roof condition issues years later.Solar.com's composite of published customer feedback, not a customer quote

Improved comfort and bills. Reviewers say the installed systems helped lower utility bills and improved indoor comfort, with less heat in summer and better warmth in winter. Representative review excerpt: "Our utility bill is lower, the drafts are gone, and the house stays so warm in winter and cool in summer."

Long-running performance. Some customers report that roofs or systems continued to perform well over many years, including later recoats or combined solar and battery projects. Representative review excerpt: "Writing this review about a year after Dura-Foam installed a new roof, solar panels, and whole home battery system for me."

Post-install repair concerns. Complaint reviews mention roof repair follow-up problems, including water intrusion findings, repair scheduling friction, or concerns about the roof condition after years in service. Representative review excerpt: "They sent out a repairman and found 8 spots where water had penetrated the foam as well as 80 suspect locations."

Bottom line: Across 236 substantive reviews, DURA - FOAM’s strongest feedback centers on workmanship and long-term system performance, with many reviewers describing professional crews and solid results. The softer areas are pricing transparency and communication, where reviewers more often mention refund issues, unclear scope, scheduling problems, and follow-up gaps.

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.
