Basement Waterproofing

Mario & the boys from MMT Waterproofing did a great job. We had water coming into the basement through a crack in the poured foundation. To get at the crack, they needed to open up our deck first, then dig down and do the job. The best part was that Mario called back the day after our first significant rainfall to check that the basement was still dry.

Waterproofing Basement Crack from Outside

After searching on HomeStars for reputable waterproofing companies to deal with the multiple cracks in my basement, I narrowed it down to three companies. I then checked out each company's website and phoned each one of them. I soon decided that it was Mario from MMT Waterproofing who I would first call for an estimate.

(I had also done my research and KNEW that so-called polyurethane/epoxy resin crack-filling was NOT the answer - only waterproofing from the outside really works.)

For the first phone call, Mario was totally professional and took the time to explain carefully and clearly his services. He didn't try to hustle me off the phone like some contractors do. He was polite, friendly and courteous. I thanked him and he asked me to call him again if I had any more questions.

So the next week, I called him over to my house for an estimate. He came down to the basement, taking off his shoes (this is important!). He looked carefully at every crack and hole in the basement walls and explained carefully the reason why they were leaking and why mold was growing there. He then explained what should be done about them. Digging around the entire foundation of the house and waterproofing the foundation walls from the outside was the complete answer, but we let Mario know that we were on a budget. So, he suggested that we repair just the areas with cracks/holes from the outside. He also took a look at our biggest crack (and biggest problem) and showed us how someone tried to repair it with a polyurethane filler that subsequently failed.

We thanked him and he didn't try to pressure us into making an appointment for the actual service.

Then, approximately two weeks later, we decided to have Mario and MMT Waterproofing fix only one crack (the most severe one) and see how well a job he did (we were being cautious, as we had bad experiences before). So, I called him up and we made an appointment. I must also mention that he totally remembered me and the layout of my house. He took the time to again explain what he would do.

Finally, the day arrived when Mario's team would come to do the work. They were slated to arrive at 8:00 a.m., but Mario phoned to say they would be approximately 30 minutes late, due to having to finish up another job from the night before. Calling when you're going to be late tells you a lot about someone's character!

They then arrived at the time they said they would, and they dug beside the house where the crack was for a steady two hours and once down to the footing, reported to us that our weeping tile was actually still good. Then, they cleaned the foundation wall where the crack was, applied their stuff (not sure exactly what all the various things were, but it included some black tar and of course, the waterproofing plastic sheathing). Then, they put gravel down at the bottom, filled the dirt back in, and put more gravel at the very top. I must also mention that we had a tonne of bricks piled up right where they were to dig, and they neatly removed them and piled them up somewhere else.

The next day, Mario came back to collect his cheque and thanked me again.

It has been about a month since MMT Waterproofing did their work to my basement and we've seen some medium-volume rain and the wet rain-snow of Dec. 9, 2009 (the first snow of the year), and it's been dry as a bone! I'll have to see how it is in Spring when everything starts to melt!

Just based on the service alone, I would recommend Mario and MMT Waterproofing to anyone out there. In fact, I will probably need his services in the future to completely fix the rest of the basement cracks (when the budget allows). In terms of actual technical skills, I can say that the job they did was A+ (based on my own research of what should properly be done).

Thanks Mario and the MMT team.

Update: It is now April, 2010 and the basement has remained completely dry! Normally, there would be a huge pool of water once the winter snow melted... but it's completely dry. MMT did a good job, that's for sure.

Basement Waterproofing & Insulation

MMT Waterproofing were on time, on budget and provided superior workmanship. Their fee was very competitive - in fact I was able to add insulating the exterior of the basement as well, which will save me money in the long run! Everything was left incredibly tidy and clean after they were finished. Mario was very patient in answering all my questions. I wouldn't hesitate to recommend them. I am happily looking forward to a dry and warm basement from now on.

Basement leak repair

I've had a wet leaky basement for about 10 years now and because I thought it was going to be so expensive and such a mess to repair I've just lived with it for all those years. WHAT A MISTAKE!!! I finally decided enough is enough! After reading some positive reviews on this as well as another site I decided to give MMT a try. I called and the next day I met up with Mario (super nice guy) and he explained what was involved and quoted the job. I immediately felt comfortable enough with him to book the job and am I ever glad I did. Mario and the crew showed up on time and did the repair both professionally and as per my wife extremely cleanly. What a good experience!! I waited a few months before writing this review just to make sure that in fact the leak was gone and boy is it ever!! If only dealing with all the trades was this easy....

I would'nt hesitate to recommend Mario and the guys at MMT any day of the week. I only wish I would have called 10 years sooner!!! All I can think about is all the money I wasted on dehumidifiers, wetvacs and the electricity to run them and all the damage I let happen be not correcting the problem sooner.
You live and learn!!!

Thanks again MMT!!

Leaky Basement

We had water in our basement close to the fuse box. Mario provided a competitive, and free written estimate and explained the different approaches to fixing the problem and his recommendation. He ended up doing the work on Labour day weekend because he was so busy. The clean-up afterwards was perfect. A few weeks later I noticed a small amount of water in the basement. One call and Mario was back to take a look. He diagnosed the issue and fixed it without a word of complaint or even a mention of additional cost. I plan on using MMT again prior to finishing my basement and I would have no hesitiation in recommending Mario and his team.

What could this company do to improve their services?
Nothing. They stick to wha they do well.
Any advice to offer fellow homeowners facing a similar project?
Be careful about a quick-fix job because in the long run it will cost more. Don't pay for quotes either.

Basement Waterproofing

I hired Mario and his company to waterproof our leaking basement after I had gotten quite a few estimates from other companies. Right from the beginning I had a very good feeling about Mario as he was very polite and explained to me what the job entailed. His description of the job was the same as all the other companies and his price was the best. He even took the time, before I hired him, to come out and speak with my husband who had not been at the initial meeting with Mario. I am very pleased with the work that was done.....I have since checked the basement after a few rainfalls and all is DRY!! Everything that Mario said he would do he did. A good, honest company and a pleasure to deal with.

Waterproofing basement

I called in MMT to waterproof my basement walls. Mario was very knowledgeable, polite and honest. When he dug down to the foundation he found the house had no weeping tiles. He was able to repair the problem by laying new weeping tile, parging, taring and putting on the waterproof sheeting. His entire crew were hard workers, polite and they obviously cared about doing an excellent job. The job was supposed to take 3 days to complete. I was most impressed when Mario told me on the first day that rain was forecast for the entire third day so he would be sending extra people in to complete my job in two days. This is what he did. He along with his extra staff worked the entire day until they finished the job the second evening. Everything was left spotless. I was having a renovation done at the house and the other contractor was so impressed with Mario that he took his number and will be using his services. This is the best experiences I have ever had with a contractor. I can recommend MMT Waterproofing without reservation.

repair of foundation leak

I recently had a foundation leak on the side of my house. I had several estimates but decided to go with MMT Waterproofing. Not only was the price better, but he was honest and hard working and did a wonderful job. He explained every step of the process and took pictures of the problem during the repair so that I could see what needed to be done and why. My interlock had to be dug up and Mario returned and relaid that as well. I am very pleased with the work that MMT Waterproofing has done and would definitely recommend this company to others.

Waterproofing Cantina & Cracks in Poured Concrete Foundation

Look no further, call MMT. It was discovered that I had 3 cracks in poured concrete foundation in 12 year old home as I had water leaking into my basement with the torential rain that we had been having. To make matters worse, I had water leaking from porch in my Cantina. When Mario & Robert arrived to assess the problem, they only provided me with solutions as opposed to other companies that would ridule the builder. Right from the start I had a good feeling and great experience dealing with Mario & Robert at MMT Waterproofing. They always made me feel important no matter how busy they were. Mario was always prompt in returning calls and very patient with my questions. He was true to his word as to when the work would begin & very prompt. He is knowledge & experienced in this specialized field. I wanted results and I have not had a leak since the work was done. I will definitely refer this company to my closest friends and relatives. Thank you to MMT for an outstanding job!!!
