Tim was great to work with, providing valuable info about aspects of the project I hadn't considered, and explaining everything thoroughly along the way. Landscape and Drainage extended downspouts, added French drains and drain boxes, and took down two trees. They also offered the best price of the three companies I got estimates from. I was so happy with the results and the experience working with them that I sent Tim to my parents' house, where he did additional drainage and tree work. Before and After pictures were all taken after significant amount of rain; you can really see the difference!

My wife and I moved into a 70 year old house on a hill. The previous owners had done quite a bit of…read morework - french drain, waterproofing the basement, 3 sump pumps, steel beam reinforced walls - but we spotted some water along the basement wall. Tim came out to look at that and a bunch of other stuff (future work), and gave us a plan to resolve the immediate issues. On the inside, his guys came out and jackhammered along our foundation, installed a new system to collect and direct any water seeping through the wall to our existing sump pump discharge line, and laid new concrete. They even worked around a bit of a curveball without needing to deviate from the estimate. Outside, they dug a 22-ft trench and installed a french drain to alleviate the hydrostatic pressure on the basement wall, routed our HVAC condensate line into the french drain, installed 2 new window wells which allowed them to grade the yard away from the house, and installed another french drain on the far end of the garden to help mitigate the flash flooding we experience there. They finished up by laying fescue sod over the affected area, making it look nice and clean. All of the work was done in two days, with some minor cleanup work on the 3rd day after the concrete had cured in the basement. The price was good, the guys worked hard, the work was done on time, and the final product was excellent. We will be using them again for our retaining walls, landscaping, and whatever else comes our way.

Working with GLM was hands-down the best experience I have ever had with a contractor. I'm forever…read moregrateful that a neighbor recommended them. We had some drainage/waterproofing issues that needed addressed, and when I found out the scope of their skills, we also hired them for a laundry list of things I had on my wish list since moving in a few years ago. These folks did it all for us! For starters, they repaired a brick wall in our front yard, installed a new sump pump drain pipe and exit, re-worked some existing exterior waterproofing that had been done sloppily in the past, and added a new concrete pad and drain by our back door. They even helped us track down an underground gutter leak and replaced the broken pipe. The showpiece job, however, is the stunning stone retaining wall, that they meticulously built by hand, across the back yard along with the new cement parking pad and stamped concrete border tapering it to our existing drive. The pictures don't do it justice (attached is a "before" photo for reference). Everything was done with great care and precision, using high-quality materials. The owner of the company, Deborah, was a gem to work with. She is super-passionate about the environment and the quality of work her company does. We worked with Gerardo and he was also fantastic. He had great ideas and suggestions in terms of practicality and design. He was also flexible with a few adjustments along the way. You can tell that these folks are truly experts in their field and take great pride in their work. I would hire this company again in a heartbeat!

Deborah is really inspiring and great professional! We called her for a quote and she was…read moreresponsive, communicative, and really informative. I really liked that she sent calendar invites for her appointments and was really organized. We didn't end up working with her since our scope of work changed but I really admire the way she does business.

From the first moment I called them, they sounded annoyed to have to be speaking with me. They…read moreagreed to go to my home and provide an estimate, which they then quoted me $8000 for a problem that did not exist. I got a second opinion, was quoted $200 for a simple fix. I then got a third opinion, because of course one of the two is either incompetent or lying, and the 3rd opinion was $225, for that same exact fix. When I then showed them the estimate from Aqueduct, they scoffed and said it was a company who was trying to rip me off and rob me blind. **BEWARE** Get additional estimates before going with them. Aqueduct, shame on you.

Highly recommend. Great experience recently with Aqueduct when we had waterproofing done in our…read morebasement. After having water intrusion in the past few years, we selected Aqueduct from several other estimates. On time, worked clean (as best you can doing work that can generate lots of dust), professional and friendly, and very fair pricing. Our basement is now totally dry after multiple days of heavy rain. VERY happy with their work!
