Constraction reviews in San Jose, California

Indaspec has been a great company to work with. We wanted to get a Franklin battery system installed before the Federal rebate program ended at the end of 2025 and they bent over backwards to qualify us for it as we approached the end of the calendar year.

They had great communication the entire time and I have been extremely happy with the end result.

I needed a new roof and solar panels on my garage These guys were great, it's been a couple years and no complaints. It was really nice not having to coordinate with a solar contractor and a roofer. Thye managed everything, permits inspections etc. The roofers did an really nice job and kept the site clean and orderly. If you need a roof, solar or both I highly recommend Indaspec.

I have nothing but good things to say about Indaspec. They expanded our existing solar system by adding 10 rooftop panels and 2 Franklin batteries. From start to finish they really were on top of the job. They explained everything thoroughly all along the way. They worked with me when I found out I could upgrade my existing inverters and buy some of the equipment to be installed through a discounted upgrade program with Enphase. When we hit a snag with PG&E, they were there to work it through. The finished job is about as clean as building codes and my old house will allow. i highly recommend them.

Indaspec energy installed my solar panels, tesla battery (3 pack) for a new construction along with the Span smart panel. They came before the sheet rock got installed to do the wiring and later to install the panels, solar panels and battery. They were easy to communicate, reach and did a great job. Wonderful support before and after. Saul was my main contact and it was pleasure working with him

Indaspec completed a project for me recently. I needed a new roof and had decided to install a battery to backup our rooftop solar system. I compared prices and Indaspec was competitive price-wise AND the roof install/solar removal and reinstall were guaranteed to be better than using two separate companies. Everything went exactly as planned and as Indaspec said, and all the personnel I worked with were top notch. The roofers even advised on some inadequate work a prior roofer had done, and we fixed that (saving me loads of costs down the road). Indaspec even advised that we reinstall the existing solar panels, rather than replace with new. I trust these folks and they did good work. Am glad to know them.

Indaspec was amazing throughout the solar evaluation and sizing process. I was very skeptical of many aspects of the process, and my engineer worked with me for a couple months, with no pressure, and took the time to go through the necessary spreadsheets to correctly size my system. The recommended panels and battery have been great. And the installation was painless even on my brand new tile roof.

We hired Indaspec in November 2023 to replace our roof and solar panels. Overall, we were very pleased with both the quality of the installation and the professionalism of the team. The entire process — from the initial sales conversations through project completion — was smooth and well managed.

There was an issue with a gutter subcontractor during the project, but Indaspec stepped up and addressed the problem promptly and professionally. Even more impressive, nearly two years later they responded quickly when I had a concern about a gutter. It turned out to be clogged downspouts (my oversight), but they still came out to take a look and make sure everything was working properly.

That level of follow-through and customer service speaks volumes. I would definitely recommend Indaspec to anyone considering a roof and solar installation.

We strongly recommend Indaspec for any solar, battery, electrical and roofing work you may need. We had a solar, battery, and main panel upgrade project that the contractor abandoned. Indaspec came and finished the work expertly and efficiently. We found out through our process that one of the founders of Indaspec actually wrote the book for inspectors to inspect solar projects. Needless to say our project quickly passed inspection. We had the pleasure on interacting directly with the dispatcher, technician, senior technician, and both owners. To a person each was professional, knowledgeable, and friendly. We had a minor issue and the senior technician and an owner came back out to our home at 6:30p on a Friday evening. They left a couple of hours later after discovering and fixing a grounding issue. I thought I would be without our electric vehicle home charging for the weekend. Who does that anymore? I have recommended Indaspec to friends and those that selected the company are happy with their project outcome.

I've used Indaspec for many different services - including backup battery installation, replacing our main panel switch, and roof repair. They are always extremely professional and do a great job. I would highly recommend them to anyone.

We had a great experience with Indaspec from beginning to end. We had an existing 18+ yr old rooftop solar system which had died and we wanted to add a battery before the tax credit opportunity expired. Diving into the project it was obvious our roof needed replacing so that was added. Indaspec jumped into the project provided a project plan and quotes. The design, permitting, and installation were well done and met the promised schedule. We had constant contact with the project manager, and the on-site workmen throughout were prompt, helpful, tidy, professional, and went the extra mile. The roof replacement which could had been quite disruptive wasn't - kudos! After installation, they showed me how to use the app and suggested settings appropriate to our situation. We're very pleased with the system and with Indaspec.

We found out about Indaspec when we ran into problems with another solar panel installer. That company had taken down our old panels so that we could reroof before installing new panels. They installed new panels that worked well, but their reinstall of the old panels was wrong and they never worked again. After many months of increasingly unlikely reasons why the old ones were no longer working, we asked around for a company to assess the old installation. Indaspec did a thorough analysis of everything that had been done wrong (there was a LOT!) and documented it with photos and a report. We were so impressed with them that we asked them to remedy the problem and to add a battery. Working with Indaspec was always a pleasure (especially when contrasted with the nightmare of the previous, now bankrupt, installer). The Indaspec team was consistently professional, knowledgeable, efficient, punctual, respectful and friendly throughout the process. Because of the complications of our installation with the two different kinds of panels and the battery, we do not have the ideal monitoring system: We can see what the production levels are, but not at the level of individual panels that we had before. It did not seem worth nearly $1000 to add more Enphase equipment to provide this level of detail. All in all, this is a first rate team and we highly recommend them!

Had to get my roof replaced that already had solar installed plus was looking to get a home battery and other electrical upgrades. Indaspec was great to work with and had competitive pricing. They were always very communicative which is great during a long project like this. Alyssa was great to work with along with Drew, Marcos, Gilberto, Andrew and anyone else that I missed. I would definitely recommend them to anyone looking to get a SPAN, battery, solar, roofing etc or any other electrical upgrade!

The entire Indaspec team is a pleasure to work with. They helped us design the best solar, battery, and EV charging system for our home and integrated it with a roof replacement. Their ability to understand our goals and needs, and convert them into an integrated plan was impressive. They were also great at completing the project on time and on budget including all the required city permitting and coordination with PG&E. Their post project support has also been outstanding. Whenever we've had an issue or question, they respond promptly and professionally. I've referred Indaspec to friends who have also worked with them and been very satisfied.

We retained Indaspec to replace our roof and add an additional powerwall unit last fall (2025). Working with Drew, Meg and the Indaspec crew was easy, efficient and delightful. They were always responsive and on time. The installers were professional and so hardworking. Adding a power wall to our existing system was challenging because of new local codes and Indaspec figured out how we could add the additional battery and pass inspection. We are very pleased with our experience and the final work product. Their pricing was extremely competitive. We highly recommend Indaspec to anyone who needs a new roof or solar work.

We had a great experience working with each and everyone on the Indaspec team. From the initial conversations through project management and final install, the team was responsive, organized, and easy to work with.

They clearly explained our options, walked us through timelines and expectations, and kept us informed at each step. The installation crew was professional, punctual, and respectful of our home. Everything was completed cleanly and efficiently.

What stood out most was how thorough they were in explaining the system after install. They took the time to walk us through the app, how the Tesla Powerwalls operate, and what to expect with PG&E and PTO.

Overall, we’re very happy with the experience and would absolutely recommend Indaspec to anyone considering solar and battery storage.

I was looking for someone knowledgeable about FranklinWH and wasn’t going to trap me in Subcontracting payment issues. After three idiots, I found David and knew I found the right company. I was right! Indaspec did a great job adding to my existing solar, incorporating batteries, and cleaning up a mess of electrical experiments added to the house over 60 years. The system worked so well, when I had enough money to add more batteries, it took David and team very little time to expand the system. I am basically free from PGE!
And when I had issues, concerns, or plain stupidity on my part, Indaspec has been there to help.
I have recommended them to my neighbors (they loved them!) and other friends. You will not have inspection nor subcontractor issues as they know their stuff and do all the work themselves!

It is rare to find a company that can seamlessly handle a complex project like a full roof replacement alongside a solar system and Tesla battery installation, but they executed it perfectly. Their team was professional, knowledgeable, and respectful of my property throughout the entire process. They took what could have been a stressful, multi-stage project and turned it into a smooth, well-coordinated one!

I had a great experience with Indaspec. We had an existing 10+ yr old rooftop solar system and we wanted to add whole house backup and upgrade our breaker panels. Indaspec provided several design options and a competitive quote. I went with them the have no regrets. The design, permitting, and installation were well done and along the promised schedule. After installation, they showed me how to use the app and switch to external generator as well. I'm very pleased with the system and with Indaspec.

I got solar and a batter installed on my house by Indaspec. I chose them because they are the recommended installer for Franklin batteries in the area which I wanted instead of Tesla because of their superiority. The team I worked with did a great job! I was well informed at each step and everything went super smoothly with them. They handled everything for me. I'm very happy with my system!
