The contractor was prompt and professional, but in the end, Colonial said the leaking pipe is due to "improper installation" since there were no hangers around the pipe and is not due to "normal wear and tear". Meanwhile, the pipe that is leaking is a cast iron drain line that has been there with no issues since the house was built in 1957...over 50 years! I'd say that's normal wear and tear.

It started first when they were taking out the concrete in the basement they decided to demolish my work bench too. Which they were not suppose to do. Then Memo the owner argued with me that it was rotted which it wasn?t. I told him the point is that they were not suppose to do that. Plus they did not totally cover my hardwood floors when they were removing the concrete so my wood floor has scratches all over it now. Then when they disconnected my hot water heater to move it, they did not cap off the end of the pipe so my water was running for 2 and half days and made a mess in the basement. Then Custom Reguirements of Maryland, Inc. put in a French drain in my basement because I had a water issue. They put the drain pipe above the floor level and the sump pump well opening is about 12 inches above the floor. So I would have to have a major flood in the basement that would be over 12 inches high of water for the sump pump to work. The well was always dry when it rained and the french drain never work. I had water still coming in and flooding my basement. Custom Requirements of Maryland, Inc replaced my work bench. But they did not put the door back on to the entrance to the basement when they were using a electric saw to make another work bench. I had a layer of saw dust throughout my house. That was another mess to clean up. Custom Requirements of Maryland, Inc. also replaced one of my studs under the staircase in the basement and that was not in alignment with the other stud. They had to redo that too. When Memo the owner came in to discuss the French drain not working and I was showing him the dark marks from water coming in on the floor, he said that was moisture and not water. Moisture and water are the same thing. Custom Requirements of Maryland, Inc. would not redo my French drain again. I just want it fixed right so I won?t have a water issue. I got some of my money back but not all of it. I finally used the sump pump for my dehumidifier to drain so I won?t have to empty the bucket all the time. And the pipes leaked that Custom Requirements of Maryland, Inc. put in for the sump pump and I had a flood on the other side of the basement. So do not let Custom Requirements of Maryland, Inc. work on your house get another contractor.

What impresses me the most about Nick, is his attention to detail and his general knowledge about gutters, downspouts and drainage. He is a craftsman in an age when few exist. The work of his company is vastly superior to that of the other three companies that I have tried previously. By furnishing photos to his client, Nick provides evidence that work has been performed properly. I am relieved that I finally have found a gutter maintenance contractor worthy of trust.

This business is excellent. Fixed our leak quickly and well.
He installed a new capacitor, then the HVAC system started leaking all over the basement floor and he said he couldn't fix it. He didn't add any refrigerant to my system, and the contractor who came in after him to fix what he couldn't added the needed refrigerant and fixed the leak. It's...

"We had our master and hall baths completely gutted and rebuilt. We bid the project out to several companies, and DMV was immediately the most helpful. Pricing was very competitive. Luis and the team completed both bathrooms in about 6 weeks - and this was a full demo. The crew was extremely kind and courteous, and worked hard to minimize the mess and impact to our home. One weekend we had a party, and they helped make our home look like there wasn’t a major project in-progress! Craftsmanship was impeccable. The tile work in particular is beautiful - details I hadn’t even thought of were done for me. Like any job, we had some changes to scope (our choice), and some minor hiccups. They were extremely helpful navigating through scope changes, and more than fair on pricing. And on the minor hiccups, they made it extra clear that the job wouldn’t be wrapped until we were satisfied - and that’s what happened. Honestly this experience was a 10 out of 10, and I hope we can have them out for another project soon. Our bathrooms went from blight to bling in 6 weeks - I look forward to getting ready now!"

"We write this review as a sigh of relief now that our renovation project with River View is finally complete. The quality of the final work is excellent, and the construction crew, architect, and county inspector were all great to work with. The original crew we worked with, led by Edwin, were so hardworking, friendly, thorough, and fast. That's what really pushed us from 2 to 3 stars. However, the process getting here was frustrating and unnecessarily chaotic. Timeline & Communication Issues: Initial promise: We were clear that the renovation had to allow us to live in our home during construction and be completed before Christmas. Early communication: Our original project manager, Cris, was personable, and early communication seemed fine, if a bit informal and sometimes inappropriately personal. Major miscommunication: Near the holidays, we discovered that the plans submitted included cutting into the roof — something we explicitly said we didn’t want. This contradicted verbal assurances and caused major last-minute changes. Project Management Failures: Poor planning and oversight: Cris and the architect’s plan didn’t align with the construction work. We had to get involved directly with the county to fix errors. Paperwork errors: Incorrect submissions to the county added delays and confusion, which we had to monitor ourselves. Last-minute scramble: We were cleaning up dust on Christmas Eve due to these planning failures. Personnel Turnover & Lack of Handoff: Cris leaves the company: No proper handover to James, the new PM, who was unfamiliar with our project. Crew replaced: The original crew, who were great, were gone; new crew had no context or direction. James leaves: Another handoff with no context — the third PM had no idea about our project or its outstanding items. Escalation mishandled: When we raised our concerns with Kyle, the CEO, the response felt dismissive, with no accountability for the previous missteps. In summary, it's a beautiful end result... but we’re glad it’s over. The process left us frustrated, confused, and frankly, exhausted."

"Avoid Guardian Basement – False Promises and Poor Customer Service Two years ago, I hired Guardian Basement to fix a water issue on the front wall of my basement. Joel came out, sold me on their system, and guaranteed I would have a dry basement. We also replaced two sump pumps and had the sump well dug deeper. The main selling point was their lifetime guarantee. Fast forward two years, and I have the exact same problem. Every time there is significant rain, water rushes through the same wall. I reached out to Guardian Basement, and Joel scheduled a time to check it out. His tone was completely different this time—defensive and dismissive. Within five minutes, he claimed, “Your system is clogged.” He made this assessment without any real inspection—just by looking at the cement floor and wall. Now, here’s the catch: If you look closely at their so-called lifetime warranty, clogs are not covered. So despite spending thousands of dollars, I’m back to square one. To make matters worse, Joel was incredibly condescending and unpleasant to deal with. After this experience, I looked into their licensing with the state of Maryland and found multiple complaints against them. I am now in the process of submitting my own complaint as well. I would never recommend Guardian Basement to anyone. Save your money and go with a company that truly knows what they are doing and stands behind their work. If I could give them a negative number of stars I would."

I would never recommend Guardian Basement to anyone. Save your money and go with a company that truly knows what they are doing and stands behind their work. If I could give them a negative number of stars I would."

FAQs for basement leak repair projects in Overlea, MD
The cost to finish a basement is $18,400 for the average homeowner. However, this cost could be as little as $2,800 or as much as $34,500, depending on the basement size and the materials needed.

Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.
Although homeowners often use the terms basement remodeling and basement finishing interchangeably, they are quite different terms.
Finishing a basement is the process of taking a basement space that is not habitable and adding elements to make it usable. This includes adding plumbing, flooring, and insulation.
Remodeling a basement means taking an already existing finished basement and changing it, often by adding or removing walls, adding plumbing, or changing the existing flooring.
