"They knew what they were doing for sure , had many cracks and broken concrete that had dropped and had a big area that was a void, by the time they were done the pieces were together and they filled in all the cracks and sealed them. The only thing now is it looks like puzzle pieces. So now I need to resurface or texture .it was awesome to see"

"Beyond my expectations! Ben Miller, the owner texted me about coming over to see me. I missed the text and he showed up at my door. He looked at the job and told me he would do it from material on his truck at no charge to me. He wanted to just do something nice for someone. His repairs were perfect, completed in the rain with a smile on his face. This man is one of a kind and I would say if you need gutter work, he's the go to person!!!"

"The "best" vendor experience we have had in our 12 years of living in Central Florida! Haley was great right from my 1st phone call to Central Florida Stucco. The owner (Barry) actually called to confirm the appointment the night before. James did the actual stucco repair. He was on time, excellent, and efficient. If you need stucco work....this is the Company!"

Basement Waterproofing FAQs, answered by experts

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.

The process might take a few days to a week, depending on the method chosen, area size, and weather conditions. Some solutions, like simple interior sealants, may require less time.

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.

You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. 

However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.
