Quacker's Waterproofing & Basement Repair has been family owned and operated since 2001. No subcontractors or commissioned sales people are used. Cost is determined by the job. Due to our experience installing waterproofing systems, fixing foundations as well as our Radon testing and mitigation experience gives us the skill sets to install Radon resistance waterproofing systems. Most of our competitors don't have this combination of skill sets there before may waterproofing systems that are installed can potentially contribute to elevated radon levels in their customer's home. We can solve most foundation/basement problems as well as improve our clients indoor air quality which is a very high priority for us. It is our commitment and responsibility to insure our customers have healthy homes and we are do nothing to compromise that. We are not tied to or required to use any propriety systems or products that many companies are vested in. We use the systems and products that we feel provide the best solution for our client's problem. For customers who want a more finished look than a normal crack injection, we offer a special surface seal that can be removed from the surface of the wall after a crack is injected leaving only the repaired crack line visible. We can also paint the basement walls to make both crack repairs and carbon fiber repairs much less visible. In addition to radon testing and mitigation we really are positioned to be a one stop shop. There are several brand name products and systems we use on a regular basis. "Fortress Stabilization" carbon fiber wall stabilization products, "Stabilizer" top and bottom adjustable I-beam brackets used with vertical I-beams for wall stabilization, and "Kryton" crystalline waterproofing products used when crack injection and other waterproofing methods will not be effective, We also use "RadonAway" radon mitigation fans for all of our radon mitigation system installation. Due to our experience repairing foundation wall cracks many times we can provide an accurate repair price over the phone with just a good discription from the client or a clear picture of the crack.

"it went fine, he came to see the problem & a week later he fixed it. water is no longer coming in."

When you have mold, making the correct decisions right away is critical. Whether it’s mold in your home, school, place of work or apartment there are many factors to consider. Are you going to be involved in a Mold Lawsuit? Will you be seeking property damages? Is anyone sick from mold exposure? Will you be seeking medical damages? Will you need expert witnesses? If so, what kind? Do you just want to test to be sure your environment is safe? Do you need Post Mold Remediation Testing to ensure a good job was done? These and other factors are questions which need to be answered before any environmental testing starts. It’s important to know what your goals are and why your testing. Different goals require different environmental tests, i.e. medical damages & property damages require different environmental tests to prove your case in court. Tests that a common or inexperienced mold inspector would not

Mold Testing and Remediation questions, answered by experts

The best way to measure moisture levels in drywall is with a moisture meter. Moisture meters feature small probes that you insert into drywall (similar to pushing a pin into the wall). Ideally, you'll take moisture readings at several locations on the wall to get a general idea of the moisture level.

Just because you find mold in your home does not mean you need to pursue professional remediation services. You can often clean small amounts of surface mold, such as in bathrooms or on windowsills, using household products. However, extensive mold growth, persistent odors, or mold caused by water damage require professional remediation. A good rule of thumb is to hire a pro when the mold is in an area larger than 10 square feet, poses health risks, or affects the structural integrity of your home.

Bathroom mold tends to reappear due to the persistent presence of moisture and humidity, creating the ideal conditions for its growth. Since bathrooms are inherently humid environments, without proper ventilation, moisture accumulates on surfaces, providing a continuous food source for mold spores. Mold spores are present in the air and settle on damp surfaces to start growing rapidly. Additionally, if the underlying causes of mold, such as plumbing leaks or inadequate sealing, are not addressed, mold will return even after removal. To avoid recurring issues, addressing the root cause by improving ventilation, fixing leaks, and maintaining a dry bathroom environment through regular cleaning and maintenance is essential.

Wood rot is not as dangerous as black mold. When comparing toxic black mold versus wood rot, black mold is a far more dangerous type of fungus for your health. When someone inhales black mold spores, it can cause severe respiratory issues. Although some people are sensitive to the spores found with wood rot, most people do not react if they inhale wood rot spores.

It’s unlikely your leaves are a hazard, especially if you get to them while they’re dry. However, a couple of rare risks exist. University studies suggest that decaying leaves can produce organochlorines, toxic pollutants similar to man-made PCBs (polychlorinated biphenyls), so avoid keeping them in an enclosed area.

Also, leaves and compost may cause the growth of fungi that can cause diseases like histoplasmosis and aspergillosis, as well as mold spores that are unhealthy for human lungs. Again, severe issues are rare, but those with compromised immune systems or allergies to mold should wear face masks when directly handling leaves.
