There have been many heavy rainstorms over the past year, but our basement has always stayed dry! Gary was a pleasure to work with from the initial estimate through the project's completion.

Still, they did outstanding work installing the French drains and I highly recommend them.

JS Masonry charged $1,200 to grind out the mortar, reapply fresh mortar the next day, and said to power wash it the day after to get the mortar "dust" off. My husband worked long with the power washer but it didn't remove the mortar (concrete) stains. JS Masonry's brother came two days later to try, then admitted the mortar wouldn't come off. JS Masonry assured me they would use a brick wash and it would come off, and yet repeatedly missed promised deadlines to clean it off. We set a final deadline 7 days later to complete the job, and no one showed. We've been left with the task of trying to remove these stains ourselves (at 66 yo) or paying to replace the whole walkway.

Our situation: We had a problem with our garage floor "sinking", that appeared after new garage doors were installed. Keystone gave an estimate, and on the appointed day/time, 3 of the Keystone team showed up at our house in Gaithersburg, MD. After half an hour, one of them got me and said that the problem was not in the garage foundation floor. Instead it was with the garage doors and the post in the middle of the garage between the two bays. Although I can't vouch for their foundation work, I am giving Keystone a very high rating for their professionalism and their courtesy and honesty in pointing out that their work would not have corrected the problem, Thank you Keystone.

We had experienced a quite heavy rains directly after being hit with roughly seven to 10 ( maybe 12 inches of snow in about 12 hours. Then the heavy rains came and dropped at least 4 to 6 inches of rain on top of the snow. Well, we live in an area called Still-meadow. Apparently, Still-meadow can be loosely translated to running water under land ( apparently it is an Native American saying to basically say in an ornate way, "Hey, you live on a a, "Flood Plain", or in our case a network of small natural springs. Oh yeah, and now you now have a unwanted swimming pool in place of what use to be your dry basement, where a-l-l-l-l your decorations for Christmas and some of your irreplaceable keepsakes from year/decades past are now about to be damaged or destroyed beyond all recognition. So who do you call??? The "Ghost-Busters"? Nope, that would be Denny Cottrell Water-Proofing ( I may have the name wrong (sorry Denny). However, one way you'll never go wrong is when you reach out to Denny and his team for help with your water- proofing needs. No B.S. just the facts and a pledge from him yo do what he and his amazing team can do to rectify your soggy situation. Trust me when I say this, "You will never regret taking your water-proofing needs to Denny and his guys. That is for sure.

We hired Cottrell Basement Waterproofing (Dennis Cottrell Jr ) to install an egress window in our…read morenew home. First of all I can't believe this man/company got so many good reviews after dealing with him for a short period of time. Did he inherit this company from his dad and then run it into the ground? I should have seen the red flag when he was so pushy to start and every other contractor I called couldn't get to us for 3-12 months. He was trying to get me to write him a check for the job even before we settled on our new house. He was extremely unprofessional from the beginning, sending me weird photos of his vacation, but I over looked it because we needed an egress window to make a 4th bedroom in our new house asap. We signed the contract May 12th and gave him a 30% deposit of $1800. Upon looking at the contract my husband immediately noticed some things that were not checked off that should be done to install an egress window properly like installing a lentil. When he asked Dennis about it he said he didn't check them off because he doesn't want the township inspecting that part, that it would just be a headache for us. Like he was doing us a favor. We applied for permits for the window and after he cashed our check he told us he is going to start without permits and if we have a problem with that that is going to be a problem and he may not do our job. He said he works without permits all the time. He's also texted us some absolutely ridiculous things. Also the fact that he was leaving out information so that certain parts wouldn't be inspected is huge red flag. If he was doing proper work why would there be a problem with inspections afterwards? Cutting a substantial sized hole in a foundation is a pretty big deal. He said he was getting a lot of backlash from us asking about permits and he would let us know the day before our job was supposed to start if he was going to show up or not and that if he canceled he would get our deposit money (that we gave him 2 weeks ago) back to us in six months(which I have 0 faith in). It's like he was almost trying to bully us into letting him do the job because he's hard up for money. He reiterated how it is paramount to put his company's financial needs first. He has put us in a really bad situation with the township. Unfortunately at this point I now decided to do more research on him than just Google and Facebook reviews. I found that he's had another lawsuit from a customer which he is still failing to pay back. But most importantly I found out he is actually NOT currently a licensed contractor with the state of Pennsylvania, that license expired YEARS ago. He said that there must be a "miscommunication" within the Attorney General's office and it's absurd that I would say that he's not licensed. This is all public info. At this point he is not responding to any of our emails, texts, or calls regarding repaying us our $1800 deposit. His story about how long he's been working and what kind of work he will do changed every time we talked to him. We have caught him in numerous contradicting statements and lies. I think he is a scam artist. Beware. After all of this he sent a text eluding to the fact that we should stay on his schedule. Um, no thanks. I'm just so glad he actually didn't touch our house. If the way he runs his business and his lack of Integrity is any indication of how the actual work would go it would be a complete disaster. I just want our $1800 deposit money back.
