"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."

"I recently asked for some estimates for painting our entire home exterior, having our three sets of stairs rebuilt, fixing several of our windows, and repairing several door jams. After reviewing the estimates in detail, I decided to go with Shane Franich of GreenFrog LLC. He was always prompt and courteous, and answered all my calls and messages on a timely basis. His estimate was very reasonable for the work being provided, and along with Marco of Prime Construction, did an excellent job on the painting and repair of our home. I would definitely use them again for any future projects!"

After living 20+ years in south FL our owner, a GA native, is bringing the highest standard of credentials in environmental testing and mitigation protocol to our region. The State of Florida requires licensure to perform mold testing and mold remediation which EcoStrike proudly holds. Even though these licenses are not required to operate in Georgia, we keep all of our credentials active and in good standing. We believe this keeps us ahead of the competition in knowledge and best practices. Every assessment performed by EcoStrike includes a complete inspection of the property including but not limited to moisture readings, indoor isometrics, air and/or bulk sample collection, laboratory analysis, and a complete summary report including protocol. EcoStrike takes pride in providing quality service with outstanding results. We look forward to earning your business and the opportunity to build a lasting relationship!

"Zach and team went above and beyond from start to finish. In a less than desirable situation, Zach did everything he could to make it better for us. I would recommend EcoStrike without hesitation. Extremely professional company. Thank you again."

We are owner operators who are out on each and every job to ensure quality is met. Feel free to check out Facebook page out as well!

"We had some floor supports and encapsulation done and couldn't be happier! Jered is extremely dependable and honest (which in today's world is hard to come by). They were extremely courteous and timely. It doesn't hurt that they were also an arm and a leg cheaper than everyone else! If you're looking for encapsulation work or floor supports then give these guys a call!"

At Precision Crawlspace & Renovations, we're conscious of the fact that the crawlspace is a section of the house that is occasionally overlooked and can cause worry for the owner. Due to this, we have made it our responsibility to provide our clients with the best possible experience, starting with the initial evaluation and continuing through the final cleanup.

"Sawyer(owner) is expert at his profession. He has some of the best technical team in the business. He is fair, honest, thorough and his work is professional, timely, and turn key. We had serious mold, mildew, dampness, bugs, and impact on our floors and support joists. Sawyer and his team dug around my foundation and installed drainage pipes, those lead to collection areas and then to pumps to expel the rain water runoff. Also the entire crawlspace was sealed and a commercial grade dehumidifier installed. Heavy floor barrier as well. He also installed more lighting and moister monitors. That was just our main house. We also have a 2500 foot guest house where the identical service was installed. That was 5 years ago and it all works beautifully- in fact when I show it to neighbors they say “dam I could bring my sleeping bag and camp out down here”. We’ll guess what my daughter got for Christmas- the same service for her home! Sawyer saved my house from more serious damage and improved our health. I think Crawlspace’s should be outlawed unless Ed built with these features. Whatever you spend you will get it back plus when you sell and know you are living well in the meantime- don’t waste time with rookies and fast Eddie - do it right and sleep better!"

We provide not only exceptional service, but the peace of mind your family or your co-workers deserve.

"On May 25, 2022 I spoke to a representative of the Mold Test Company and explained that I had recently inherited a property and had not been lived in for quiet some time and was beginning the restoration process to make it livable again which included having a mold test completed. I was quoted $499 for the complete test in addition to a $50 deposit that was required to confirm appointment. I made it clear that I currently lived over 4 hours away from the property needing the test but we agreed upon a date and time that worked for all parties. Deposit was paid over the phone for confirmed 11am on 5/29/2022. I arrived at the property at 10:40am yet the technician called me about 15 after 11am to inform me the he was 15 minutes away. Arriving at church 11:30. We walk through the property and he gives me some information and points out a few things and then prepares to set up his equipment only to realize he would need a generator to complete being that the home isn’t occupied and has not been for quite some time, there is no electricity. I point out that I was not informed the equipment needed electricity although I mentioned the property had been closed up for years when making the appointment. As the expert and professional this should have been clarified prior to confirming appointment or taking payment. Technician informed that he had a generator but it wasn’t with him and he lived about 2 hours away so the appointment that I had driven 4+ hours to make would have to be rescheduled. It then took almost a full week for someone to return and follow up about this issue in which the solution suggested was to Mail this company the keys to my property to conduct the test in my absence and hitch was a red flag because I don’t know them for one and if I’m not there to see them test my property how do o know they’d even travel back to my property and complete a test instead of just telling they did and charging $499. I refused to send my keys and instead asked for a refund of my deposit. I was told he would submit my request and ended the call About a month later I still had not received my refund or any communication of it so I called and after several attempts spoke to someone who informed me that my refund request was denied because the technician said I refused services at the door and something else about canceling rescheduled appointment when nothing was every rescheduled to begin with and service was not completed bc technician did not have the necessary information equipment. I total LIE over $50. My $50 that I work hard for and have already been more than inconvenienced over. I have tried multiple time to remediate this issues but I just keep getting shuffled around to leave voicemails and no answers about my money. This is extremely unprofessional and unreasonable. I will follow up with the BBB and CFPB as well. Unacceptable and should be removed as a reliable referral from Angi"

Mold Testing and Remediation questions, answered by experts

If a professional mold inspector finds mold in your home, they’ll conduct mold testing to determine the type of mold species and the number of spores in your home. This plan will help develop a remediation plan, where a mold remediation specialist will remove the spores from your home. Since mold remediation costs the average homeowner $2,225, it’s best to treat mold at the first sign rather than waiting.

Slime mold isn’t toxic to your dog, even if they eat it. Toxicity and comfort are two different things, and if you notice your dog eating slime mold, you should stop them, but not worry too much. Expect a period of gastrointestinal distress, and possibly some other complications, but your dog should be ok within a few days.

It can be challenging to know if mold is growing behind walls without knocking them down. If the walls show signs of water damage (discoloration, water stains, or peeling paint) or there’s a musty odor, it’s possible mold is growing. Know the difference between signs of water damage vs. termites because termite infestations are sometimes mistaken for water damage. A more subtle sign might be your own health: If you’re constantly not feeling well or are sneezing, scratching your eyes, or coughing when in a specific room, you could have mold.

If you’ve spotted a skunk or know that one of these furry creatures sprayed one of your family members, your answer is fairly obvious. However, a skunky smell in your house that isn’t coming from these critters may be a sign of a dangerous gas leak. If you suspect this, leave your home immediately and call emergency services. It could also be a build-up of dangerous gas in your home’s septic system or plumbing. Call a professional plumber near you to make an assessment.

If you see black stuff under your vinyl flooring, it’s probably mold. There is a chance it could just be dirt, dried-out adhesive, or slight water damage, but some of those are causes for mold growth, so you should remove it immediately anyway. In some older homes, it could be black mastic asbestos. If you think it could be this–you guessed it–call a pro.
