"We were referring to Target Radon Mitigation by our inspector for our house inspection. I called Steve on Friday to set up an appointment to get the radon levels in a house we were under contract on tested. Steve was super friendly and stated he would drop the test off first thing Saturday morning and we should have the results of the test within 72 hours. That would make our results come in on Monday, Tuesday at the latest. Called on Monday, was told wait another day. Called Tuesday, was told wait another day. Our realtor and inspector called us and told us over the weekend a test was not dropped off. I called Steve and asked what was going on. He promised he dropped a test off and did not know why the results were not yet in. He called the lab on Thursday and they stated the test was never received. He called USPS and they said it was at the post office. If it was overnighted as Steve promised us it was, it should have gotten to the lab Tuesday at the latest. We ended up canceling the order completely. I am not sure if the test was ever really done, but what a headache. Steve was very rude and defensive when confronted about what was going on. After we asked Steve if he ever did the test he said we were calling him a liar and fraud. Steve called our inspector and ripped him a new one. I feel this is extremely unprofessional. Because of all of this, our inspector and realtor both refuse to use this company in the future."

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."

PROTECTING BY INSPECTING! Lead poisoning is no laughing matter. Worldwide, about 143,000 deaths per year result from lead poisoning, and lead paint is the most common perpetrator. You can prevent lead poisoning from taking a toll on you, your family, and your home by having your property inspected. Reliable Lead Inspection Services, LLC has helped countless homeowners across Baltimore, MD and the surrounding counties with their home lead inspections since 2014. The state of Maryland requires that all properties – including apartments, condos, townhouses, lofts, and single-family homes – built before 1978 have a new lead inspection certificate every time the property is rented or sold. Even if you’re not in the market to buy or sell property, it is always a sensible decision to have any home inspected before doing renovations. You never know what could be hiding in those walls! I can provide 24 hour results if needed. Available 7 days a week. MDE Lic #15208 Ask us about our Senior, Police, & military discounts!

"Lesson learned. Always get an estimate. BEFORE the work is done. At least a digital copy. Arrangements for the project were made, with some one named Lynn, for the company to send someone to complete the work. We were quoted over the phone 4500-5000 which included a mold test. A sub contractor with an entirely different company (National Mold Company) was sent. When the contractor arrived, he stated that the job would be much more simpler than first thought. This led us to believe that the job would cost less, no. All said and done, they charged $5500. All said and done, it's almost like no work was done. The stains and the smell are still there. Only one actual board was taken upon the attic room. The ceiling in the bedroom was primed and painted but are still visible and have a funky smell. At this point I'm going to. Do what we should have done; Do the job ourselves. Just now with $5500 less dollars in our pockets. A detailed receipt was not given even though it was requested."

FAQs for radon gas abatement projects in Havre De Grace, MD

The only way to know whether your home or water supply contains radon is to schedule a professional test. A qualified radon inspector will collect samples, deliver lab-verified results, and explain the findings for $150 to $800. Once you know your exact levels, you and your radon mitigation pro can choose the right system and tackle the problem before it affects your family’s health.

Both roles tackle radon, but they focus on different steps. Inspectors test your home, interpret the results, and determine whether levels exceed EPA guidelines. Mitigation pros design and install the system that lowers those levels. Some companies do both, but the skills and equipment differ, so always verify that the person you hire is properly certified for the specific service you need.

Installing a mitigation unit fixes radon problems by reducing indoor gas levels to established safe standards. A system designed and installed by a mitigation expert, tailored to your home's specific layout and foundation, guarantees effective radon reduction. This expert installation ensures consistent performance over time while safeguarding your indoor air quality.

Open windows and doors do not reduce radon levels because they trigger a pressure imbalance that draws radon-laden air into your home. This practice fails to control radon concentration and can even worsen the issue. An active suction mitigation system provides a proven, safe, and effective solution to reliably reduce radon levels.

Radon mitigation systems generally last between 10 and 30 years, depending on system type and maintenance. Passive systems endure the longest because they have no moving parts, whereas active systems, which use a fan, require fan replacement every 5 to 10 years. System components, such as PVC pipes, seals, and fittings, can remain effective for decades when paired with periodic inspections and proper maintenance.

Radon mitigation systems consume between 300 and 3,000 kWh of electricity per year, depending on fan size and system design. On average, an active radon fan draws 100 to 300 watts continuously, which translates to roughly 876 kWh annually, and adds $30 to $300 to your energy bill each year. Choosing a high-efficiency fan and ensuring tight sealing around pipes helps minimize these ongoing costs.
