Brandon had explained the process and our options well, and they were able get all permits in place and start work earlier than expected. Care was taken to respect the landscaping, and protect the water supply. Thank you all! We can highly recommend this crew."

"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

To ensure your basement walls are waterproof, it's crucial to address any existing moisture issues before finishing. Inspect for signs of water seepage, such as dampness or discoloration, and repair any leaks or cracks. Install a vapor barrier to prevent moisture from penetrating the walls, and consider waterproofing paints or coatings.

Proper drainage systems, such as interior or exterior waterproofing, can also be beneficial.

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

Preventing water accumulation involves regular inspections, maintaining effective drainage systems, ensuring proper roof maintenance, and taking preventive measures against heavy rainfall or floods.
