Cardona Construction -

Our home had some drainage/moisture issues so we had a French drain installed by Cardona Construction last week and I highly recommend them. They installed a French drain with a surface drain line on top, connected the downspouts, and installed a channel drain at the bottom of our driveway. They also installed a sump with a battery backup.

I took bids on this project in July/Aug and Rene Cardona’s bid was both competitive in cost, and included all of the elements we asked for (including a battery backup and city permits), which was not true of the other bids. Rene came out twice to explain their design and how the process would work. Once we accepted the bid, we were on the schedule for late October. In the meantime, Rene got the permit approved from the city.

When it was time to start, Fernando (Rene’s father) led the team of six to start the work. It took six work days for the team to complete the drain and their electrician set up the outlet for the sump pump and backup pump/battery on the 7th day. Fernando’s team was efficient and cleaned up after each day.

Once the work was done, Fernando explained how the system worked and how to properly maintain it.

The project was efficiently done and between Rene and Fernando all of our questions were answered. Their work passed all city inspections and the inspector told me they did good work. We haven’t had any heavy rains yet to test the new drain, but we’re confident it will address our drainage issues.

Again, we are grateful for the work Cardona Construction on our French drain and highly recommend them.

After many winters of dealing with water coming under our house and flooding our basement, and after trying many DIY remedies, I finally decided to have Cardona Construction install french drains at my house. They are a new company, but many of the guys there have decades of experience doing french drains, particularly in the Berkeley Hills. I really enjoyed working with them, their communication was great, and everyone was very friendly. Most importantly, this time when the big atmospheric river came along I saw absolutely 0 moisture anywhere under my house - so the drains work!

I highly recommend Cardona Construction.

We hired them to dig a French drain on the uphill side of our house. Rene visited several times and discussed my options in detail. Their bid price was very reasonable. The work proceeded quickly and smoothly, with no issues whatsoever (incredibly rare for a contractor project!)

During the work, they were very proactive about asking questions about project details to make sure they were delivering what I wanted. The finished product was gorgeous; they took the time to make the pavers and backfill look nice and pretty. They also cleaned up the site thoroughly before they left.

And last but not least, they were just about the friendliest construction team I’ve ever interacted with!

We recently worked with Cardona Construction on a project involving concrete pouring and awnings construction and were very pleased with the results. The team was professional and attentive to our needs, ensuring the project went smoothly from start to finish.
Their work was solid, and they communicated well throughout the process. The final outcome met our expectations, and we appreciated their reliability and efficiency.

Overall, Cardona Construction did a great job, and we would recommend them for concrete work.

Rene at Cardona Construction along with his crew did a stellar job installing a French drain at my house. They showed up on time, stuck to their price, and did outstanding work. Beyond that they were very pleasant and willing to explain exactly the “what and why” of the process. They also left the site Spotless. I highly recommend them!

I hired Cardona Construction to replace my old concrete driveway and a section of patio. The sidewalk in front also needed replacing, which required a city permit. The city inspectors were very strict about ADA compliance, and had the contractor do the sidewalk a second time—a lot of extra work that I was not charged for. In the end, I was very pleased with the professional quality of the final product, and neatness of the work site. Rene Cardona was always easy to reach and work with, and answered all my questions promptly.

We got to use Cardona Construction for a roof job. Rene was very efficient and very reasonable in pricing. I would highly recommend them. They do phenomenal work.

We had a great experience with Cardona Construction. Rene and Fernando were nice and easy to work with. Our driveway looks excellent and the price was fair.
