"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

One handy thing about whole-house dehumidifiers is, once installed, you don’t have to worry about placement or changing the dehumidifier’s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

Flooded basement cleanup can take anywhere from a few days to several weeks, depending on the extent of water damage, the type of water involved, and the need for repairs or mold remediation. Severe cases with structural damage or extensive mold may require longer timelines. Quick action and professional help can speed up the process and reduce overall damage.

A crawl space is an area under the house that provides access to plumbing, electrical, heating ducts, and other HVAC units. Its purpose is to create a buffer between the ground and the living area, helping with ventilation, moisture control, and access for maintenance or repairs. Crawl spaces are most often seen in houses in North America which are built on concrete foundations versus other parts of the world where buildings are constructed differently.

It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it’s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible.
