Hi [Member Name Removed], thank you for the feedback, much appreciated! - MLC


Teressa M.

They excavated half of our basement that was all dirt and then put up retaining walls that extended to the foundation. After doing a lot of research, I chose M. Leon to do our foundation repair because they were recommended by several other contractors and they gave me the best price. Pascal and the workers were all lovely people and easy to have in and out of my house for three months. They resolved all of my concerns quickly and went above and beyond the scope of the contract on some of the details. Our neighbors had the exact same work being done on their house at the same time, and M.Leon finished our job at least a month ahead of them. I've already recommended them to another neighbor (we all have the same basement issues) and would recommend them to anyone who asked. They worked hard and did a great job. I'm very pleased with the outcome.

After purchasing our first home, we had a reputable company come in to give us a bid for earthquake retrofitting. When looking in our crawl space, the estimator pointed out two cracks and told us we had a big problem. He said that our house had active differential movement, and the cost to save our house would be around $20K. Thankfully, our realtor, recommended we have m. Leon construction out to take a look. Pascal was courteous, thoughtful, and incredibly patient and knowledgeable. He assured me that he didn't see anything I should be worried about, and offered some simple suggestions on how to keep the cracks from worsening. The few issues that he did find, he provided a timely and honest I'd for. This company literally saved us $20,000!!!!

They did an amazing job! We had Pascal come give us an estimate a few years ago before we had the work performed. Our basement flooded in August due to a garden hose/ watering issue. Pascal sat my husband down and asked a ton of questions and suggested waiting a year to see if it leaked during the winter. No other company made this reasonable suggestion. Pascal and Lorraine were always super nice to speak and work with. The workers tidied up every evening and made sure wholes were covered and the area safe. They did a fantastic job cleaning up and even unearthed bricks that had been buried with soil and ivy and used them to edge the river rocks! It looks beautiful! That all said, fingers crossed that this does the trick to keep the water from seeping into our basement. They just finished the work a few weeks ago and it is July. So we'll find out this winter how successfully the drain works. My biggest complaint is how difficult it was to contact an actual person. After leaving several emails and phone messages I only heard back from them after I, politely, told them I would start calling other companies to bid the work if they had too many projects going. So getting a hold of them is a bit troubling, but perhaps after this past awful winter they truly are extremely busy and a bit over worked.

Not able to get a response after bid was done.

Description of Work
I liked the work they did in the past. Now, however, I am unable to get them to respond to my questions about a bid they made on my foundation work. Very frustrating! I have left phone messages and emails. No response.

They did a super job keeping our house clean while this all went on. The workers and management were very nice and communicated really well. They ran into a couple of snags while they were working but kept the price to the "agreed upon contract" which we really appreciated. They are a family run business who have been into this kind of work for a long time. We completely appreciate their work and would hire again in a heart beat!!! Thank you! Brent and Laura

Description of Work
They dug a trench along the inside of my foundation, every room, placed perforated pipe, rock and sunk a hole for a new sump pump. They also cleaned up, replaced insulation and black sheeting throughout our crawlspace.

Lori K.

I received a bid last year, but needed another evaluation. A appointment was scheduled and he did not show up. I called and checked to see if something happened and received voice mail so I left a message. His daughter (who is the Office Manager) called and apologized profusely so I made another appointment on a Saturday (she was accommodating my request). I was there on Saturday promptly at our scheduled time, and again, no show. I did not receive another call back this time and consequently did not use his services.

It went very well ... and it was all done in a very timely manner. How and where the water was coming in had us stumped for days. At first we thought we had the solution. The rains came and so did the water come inside the house. Pascal looked at it from another angle and figured it out. All the work done was all needed and performs well to this day.
