"I contacted Angie s List seeking mold removal, I received contact from eversafe. They came out to give me an estimate. He stated he could start immediately. He said he would send me a contract to signed. I told him I needed to print it out i border to review the contract then I would sign it. They came that Monday did a little work and asked for payment to get started. I paid him the 4000 to start. They came that Tuesday and actually began the work saying they would be finished by the end of the week. They removed everything to get to the baseboards and the drywall that needed to be removed. They removed the flooring as well. Upon removing the flooring I noticed the water was only in the kitchenette area and not as he stated through the entire basement. He removed doors as well. No mold on doors.. I told him that the price would have to be readjusted because the flooring didn t need to be replaced. So daily he came up with something else that needed to be repaired. He said the toilet wasn t screwed down properthe wrong part was put on the furnace, by the end of the week they were not finished. The work continued into the next week. They worked Monday, Tuesday he worker had the stomach flu, they did not show up. Wednesday they showed up to work, but o. Thursday only his worker showed up. On Friday his worker showed up and after asking said his boss was he said he was busy. He began to remove their tools out. I m thinking he is cleaning up to finish the work. He told my partner his boss had started other job. I called him and didn t get an answer I left messages for him to call me back but he didn t. So week two and work isn t completed and now he s not answering.!I had paid him another 1000.00 on Monday or Tuesday. So this Monday August 4th I waited, no show no call. I called twice, no answer. I texted he responded saying he never received calls from me. He began to text which I have copies of them all. He now wants the signed contract in order to complete the work. I refused because now I don t trust him. He claimed the materials he purchased was 5000.00. I told him show me the receipts. No receipts. I have pictures and all text messages also phone records from when I call. The work is still not completed."

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."

FAQs for toxicity and mold removal projects in Arnold, MO

Remediation should keep mold from returning as long as the moisture source is eliminated. Fix leaks, control humidity, and replace water-damaged materials, then schedule periodic inspections to stay ahead of new growth. With those safeguards, your home can stay mold-free for the long haul while protecting both health and property value.

Most pros recommend leaving the home while they work on mold remediation. Removing mold stirs up airborne spores that can aggravate respiratory issues, and contractors can work more efficiently in an empty space. A short, temporary relocation keeps everyone in your family safe and lets the crew finish the job without interruption.

Mold shouldn’t return once the moisture problem is fixed. Stay vigilant: repair leaks right away, keep humidity below 50 percent with a dehumidifier placed in damp areas, and improve ventilation where needed. Routine checks for leaks and mold and quick repairs go a long way toward keeping your home mold-free.

Mold spores can trigger nasal congestion, throat irritation, coughing, wheezing, eye irritation, or skin rashes. People with asthma, allergies, or weakened immune systems often feel the effects sooner and more intensely. Some molds also release mycotoxins linked to serious respiratory or neurological issues. Swift remediation and better ventilation are the best defenses.
