For over 66 years, '58 Foundations & Waterproofing has provided the highest-quality basement waterproofing, crawl space encapsulation, foundation repair, and mold removal. We lead with a promise of Trusted Five-Star Service, which means the customer experience is at the center of everything we do. Since 1958, we have been steadfast in keeping this promise and upholding the values upon which '58 Foundations & Waterproofing was built: trust, teamwork, integrity, respect, and communication. From the initial call to job completion, our customers are met with knowledgeable, caring, and professional staff prepared to offer a five-star experience that is unmatched in the home repair industry. What’s more, you can enjoy the peace of mind that comes with our lifetime warranty and our industry-unique money-back guarantee!

"If you’re considering 58 Foundations, do yourself a favor and stop right now. I cannot, in good conscience, recommend this company to anyone. Their complete disregard for accountability is infuriating. At first, things appeared to go smoothly, but the illusion of competence quickly disintegrated when it came time for the building inspection. The city inspector requires a letter from the project engineer verifying that the work is safe, sound, and compliant with code. 58 Foundations flat-out refuses to provide this basic validation of their work. Why won’t they stand behind their project? Are they hiding shoddy, substandard work? As a homeowner, I’m now saddled with the mess of an open permit and no resolution in sight. This is unacceptable. If a company won’t back their work with a simple letter, what does that say about their integrity—or lack thereof? Didn't expect this kind of run around from a well established professional firm, save yourself the headache."

With over 40 years of experience in septic tank installation and service, Eagle and Son Septic Service is a family business, consisting of the owner Nathan Eagle, his son, and a good friend, who's just like one of the family. Nathan got started in the business at 15 years old when he was offered a job in the septic industry. 10 years later, in 1987, he started his own business. More than 40 years later, he is an expert in the field and focuses his experience on providing a personal and personable relationship with each customer.

"Nathan Eagle was wonderful to work with. I had quotes from other companies including one that gave me a multi-page contract with all kinds of exceptions so one really didn't know the final price, and then I received a quote from Eagle. Gave me understandable quotes that included all I needed. Due to our new septic not being at least 100' from our well, he changed his quote to install a BAT septic system per Baltimore County. His second quote was more than I wanted to spend, but the county had a grant program with funding available that paid for most of the cost of the new tank and its installation. He was usually available when I called or texted. A hard-working person who's actually hands-on."

Drain Pipe Installation questions, answered by experts

You should never pour antifreeze down the drain or outside on the ground. Because it's highly toxic, antifreeze can still impact people and animals long after it drains. Antifreeze can contaminate water and sewage systems, and any that gets into storm drains and water supplies can attract animals and harm those that ingest it.

Water heater pipes can freeze in one night if outdoor temperatures are cold enough. The lower the temperature, the quicker plumbing tends to freeze. If your pipes are well-insulated and you take proper preventative measures during the winter, your pipes should not freeze as rapidly as unprotected pipes might.

Draining is the process of removing sediment buildup that has accumulated at the bottom of your hot water heater’s tank. Flushing is a more elaborate process that involves running fresh water through the tank to clean the inside thoroughly. You should at least drain your hot water heater once per year and flush it every other year—better yet, alternate between draining and flushing every six months.

Pedestal sinks typically come with two pieces: the pedestal (also known as the base or pole) and the sink basin. You may hear it referred to as a standalone sink. The sink sits on top of the pedestal, which attaches to the floor and hides the plumbing. Both pieces usually come in porcelain or ceramic. 

Sealant doesn’t need to be applied to the bolts, but it can be a good way to stop an active leak in the moment. However, don’t rely on it as a cure-all; instead, make sure to fix the problem at the source by changing or tightening the bolts. 

If you do use sealant, make sure to spread it thickly and evenly across the bolts and the tank's porcelain.
