Guardian Basement Waterproofing understands your basement waterproofing needs. We know how to detect the source of water intrusion and stop leaks before they happen. We help our customers reclaim their basements from water, mold and mildew by doing what we do best: finding and repairing the source of their water-related problems. Guardian uses only skilled and experienced technicians to do the job right the first time! As a basement waterproofing company with more than 40 years of waterproofing experience, Guardian stands behind its work with a Lifetime Guarantee. Additional phone number - (410) 484-9812.

"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."

Biohazard Remediation questions, answered by experts

Yes, you can use a dremel tool to cut plexiglass. Follow the instructions under “How to Cut Plexiglass with a Saw,” and use a dremel tool with a 561 bit instead of a saw.

Removing the original paint or stain before refinishing is a good idea, as it ensures the new finish bonds strongly to the wood. If you skip the stripping or sanding step, the new finish may peel or flake away from the railing easily. Using a wood stripper will completely remove the old stain or paint while sanding will help to prime the surface.

In general, yes, it's worth repairing an appliance over replacing it. If the repair will give you more years of reliable service from the oven and the repair costs less than buying a comparable new model, then yes, get it repaired. If, on the other hand, the oven is reaching the end of its life and needs a costly repair, you're likely better off buying a new oven.

Regular cleanings with soap and water can leave behind streaks and hard water spots. To keep your black glass stovetop shiny, keep a spray bottle filled with a 1:1 solution of vinegar and water. Spray the surface with this solution after every cleaning session and wipe clean with a dry microfiber cloth.

To get rid of the smoke smell in a microwave, scrape off any burnt food residue and throw it away. Next, warm a cup of water in a microwave-safe container for three minutes. Then, dip a microfiber cloth into a mixture of water and a couple of drops of dish soap and wipe down the inside of the microwave. Dry the inside of the microwave with a fresh cloth and let everything air out for three hours.
