"A soft wall due to improperly installed gutter by some other entity or homeowner caused water to constantly leak into the wall from the exterior roofline. This soft wall grow moldy and become riddled with pests/bugs. The contractor identified the potential issues, agreed to explore and open the walls and discuss the conditions, made sound recommendations for repair and did exactly what was noted in the repair (replaced a load bearing exterior wall, fixed the sill plate, completed the roof, shingles etc. and closed up the walls on the inside with insulation and sheet rock.). The work was timely, well done, the workers were clean as they did the job and kept the rest of the property clean. The manager of the job David Apel was and is an excellent communicator with phone/email/text and photos of processes and progress. I am going to use this company in my own investment endeavors on other properties and projects given the level of finished work, the timing and especially the level of detailed communication."

"My review of the work I have had done by Thomas Gianni & Sons Inc.. They really did a great job of working on my property. I call their office and asked to get some excavation of removing a couple of tree stumps in my yard and to put down approx. 20 yds. of gravel in an area near my shed. It was just about three or four days and they call me back to confirm to come out the next day, June 22. Their employee came by early in the morning and went over all the project. Figured out what equipment he needed and measured up for the materials and started the work about an hour later. He was very cautious and caring about minimal damaging to the yard. After removing the stumps he graded the surrounding area with the machine to the point where I only needed to rake it out to plant new grass. The gravel was put down flat and clean; not a mess. I would definitely hire them again."

"Honestly, we cannot say enough good things about Drainage Pros. They are professional, competitively priced, trustworthy, and - most importantly - excellent at what they do.
We moved into a 1920s home with major drainage problems. Four of the six original underground drains that collected water from the downspouts were nonfunctional. Our home also sat low on the property, and when it rained water flowed across our driveway, over the patio, and into our basement by seeping over the foundation. It looked like a small river coming toward our home and disappearing underneath.
AJ responded quickly to our initial inquiry and met with us on site to discuss the project. He listened carefully to our observations while assessing the driveway, patio, and grounds before sending us a detailed proposal the next day. The proposal listed several different stages and options, which we continued to discuss with him at every step of the project. AJ was always very knowledgeable, communicative, and professional, responding to our many questions and concerns thoroughly and patiently (even when we asked the same question multiple times). Ultimately, Drainage Pros stood by their original proposal, working within budget, and they even guaranteed their work (although we don?t expect we?ll be needing the guarantee).
They tore out and had the old driveway re-graded and repaved, installed a channel drain behind part of the home, and laid pvc pipe along the entire perimeter to collect water from all six downspouts. They ran the pipe under two bluestone patios and walkways, all of which they reset carefully. They connected the pipe to our main sewer line, which required six foot plus excavations. Lastly, they reseeded the lawn (which returned nicely), and basically restored the grounds to their original condition. The paving company they coordinated with was also excellent, and they worked hard at communicating with each other to ensure that the project was completed to our satisfaction.
Personally, what I most appreciated about working with Drainage Pros is that AJ did not trouble us with all of the things that could possibly go wrong while performing such a major job like excavating and tapping into the main sewer line. He simply assured us calmly and professionally that he and his team could do the job, and they did. Perfectly.
We had previously discussed the job with a completely different (and also highly rated) contractor who appeared flustered by our drainage issues and, after charging us >$1,000 for an assessment and cleaning, was unable to offer us a written proposal or estimate without further ?diagnostics?. Do not waste your time and money, like we did. Just hire Drainage Pros, and they will get the job done.
We now have absolutely NO DRAINAGE ISSUES and strangely even look forward to when it rains so we can see how beautifully the water flows down the driveway, into the drains, and away from the house. If you are on this site searching for a drainage specialist, perhaps you can appreciate this.

"With their assistance my inland wetlands permit application was approved quickly by my town. The work involved installation of drainage and regrading my entire back yard to bring the lawn back up 14" due to erosion over time. The work was done timely. The extra work included a beautiful new rock wall as well as an excellent exterior basement door entryway. The yard has been reseeded once after the initial seeding and will be reseeded again during the fall. The company takes pride in their work! Pricing was fair as well."
