"They advice, and had all our questions answered on sensible and affordable options. Very knowledgeable, prompt, polite, efficient, and thorough team! We are happy with their waterproofing services in our basement (fast sump pump and a grate trench with a discharge line that goes 15 feet to the outside bubbler) as well as crawl space shield installed under our addition. It works well, and Pioneer checked a month later and a year after for inspection and cleaning. A+ work and workers."

"I've come across some very unprofessional contractors. I would say 90% of the contractors I have dealt during the remodeling of my home never called back or looked at my job and never returned an estimate as promised. The good news? ALL PRO Waterproofing isn't one of those companies. They were AMAZING. They sent someone to give me an estimate immediately - they called quickly to conform the install and they always showed up on time and ready to go. ** I would have given them 5 stars, but I found the price a little too high - but other than that - if you need basement waterproofing done right, don't waste your time with anyone else and call A"

"It went WELL! These guys are huge helps! They arrive faster than promised, they charge what they promise. There are no surprise charges like with a dumpster! I am now using a BullBag in CT and one in RI. I, alone, can keep this company busy!!!! They are awesome to work with! I HIGHLY RECOMMEND THEM! One of their managers, Vicki, was so nice, pleasant and patient with me. I was frazzled with all of the damage my property received from the hurricane. She was great!"

"Dennis came by promptly and gave an estimate on price and on when the work would be done. They were able to get the job done a week early (because parts for the drain channel came in on time and they has a space in their schedule). The team (led by Dennis' son) came on the day specified and on time and worked steadily until it was done (and done correctly). They swept up the footprints (rock dust and cement dust and whatever) tracked between the basement door and garage door. They even set up the dehumidifier I bought so it drains into the sealed sump directly. The installation meets the buyer's requirements and looks nice. It's definitely an upgrade for the basement space. Carol (the owner and Dennis' mom) and her office team were also a pleasure to work with on this basement waterproofing job. Since the office was less than 2 miles away from our home and time was short, I went there to execute the contract and place the deposit (rather than waiting for the postal service). You can contract and schedule remotely (via phone, mail, etc.) but then you wouldn't have the pleasure of meeting a team that loves their business and wants to do right by the customers."

"Though it took a little while for them to get back to me at first, they did set up an appointment to see the job rather quickly. However, then there was a wait again before the appointment was made for the actual work. They only sent one person to do the job, which surprised me, but he seemed to know what he was doing and was capable. There has been no further leaking in the basement, which I hope is due to the good job they did and not just to Mother Nature's unpredictability. A warranty comes with the job and I hope I will not have to submit a later report if ever I need to call upon it. I paid both the deposit and final balance with a credit card. I got a receipt for the deposit, but never was given a receipt for the final payment. I even called and wrote a letter specifically asking for them to send me a receipt for the final payment, but they have completely ignored my requests (it's been months since the job was done)."

"Mr. Cardilli subcontracts his work out and oversaw the construction. He helped us figure out what to present to the insurance company so that the majority of the work done was eventually covered by our home owner's policy. He was in constant contact throughout the project. He helped us develop a plan that allowed us to remain in the house during construction except for the floor refinishing. This was an important factor for us. 
He remained in constant contact with us about the process, what we needed to do and by when. He checked in on the job daily either by phone or site.  The construction crew he hired was excellent. They were very thorough in their daily clean up of the house including little conveniences like plugging in alarm clocks and setting them to setting up our beds in other rooms during construction.  The painting crew was good, but work needed to be checked for thorough paint coverage. We found paint on bed spreads, curtains, and floor.  They did not clean up as well as the carpenters. The flooring crew completed their job within the given time frame and the work was excellent. All work was completed within the expected time line. 
This was the first time we have ever hired a contractor to do work for us. I will add a couple of things we learned in the process. If you want / need an itemized list of all work and materials used, put that expectation in the contract. Additionally request that any work beyond the agreed upon work is approved (cost) prior to starting the needed work. When the additional work is done, check the work and time required for labor to be sure it is accurate.
Overall this experience was a good one. The subcontractors were polite and pleasant to our family. Mr. Cardilli was attentive and responsive to all our emails and calls.

Basement Waterproofing questions, answered by experts

Interlocking garage tiles made with PVC are the most effective for garages with past issues of humidity and flooding because damp concrete is not suitable for paint. Epoxy coating is also water-resistant and can prevent mold buildup. Finally, porcelain tiles are a wonderful option for wet conditions if your budget allows.

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.

Water leakage through window openings is much more common in older homes, but it can also create issues with window frames that are improperly installed. If left unattended, water buildup can cause damage to surrounding fixtures, lead to harmful mold, and compromise the architectural integrity of your home. The potential damage that a water leak poses makes investing in weather- and water-proofing your window frames entirely worthwhile.

Yes, it is possible to over-dehumidify a house by removing too much moisture from the air. This can create an overly dry environment that negatively affects those with respiratory or skin issues, and may cause your skin, hair, and sinuses to feel dry. However, this is unlikely to happen with most modern dehumidifiers, as they are equipped with moisture sensors and adjustable settings. These features allow the unit to pause automatically when the desired humidity level is reached, preventing the air from becoming uncomfortably dry. In contrast, older or more basic dehumidifiers left running for too long could potentially over-dry the air. To avoid this, aim for a balance between removing excess moisture and maintaining a comfortable environment. You can often monitor your home's humidity levels using a modern thermostat for guidance.

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.
