"Angel was responsive to my inquiry by email. Came out for an estimate to install stock cabinets, counter top and sink as well as all the plumbing. The day he was scheduled to come to install he called me to explain he had made a mistake on his estimate and wanted to talk with me first because he said he would not just come to do the work then tell me, this was for $20.00! that impressed me a lot. He was so careful of my home protecting the area he worked in he did a quality job! He was efficient an organized."

"I hired RE Construction to grade a sloped driveway. Robert made the process easy and turned my idea into a reality. I can’t say enough about his professionalism and attention to detail. I’d recommend RE to anyone and will use their services again in the future."

"Ed Madruga came out promptly, and was very helpful, knowledgeable, and forthright. He was so helpful, I may end up doing the project myself. If not, he will likely get the job. Later, I came to my senses and had him do the job. He had the right equipment and knew exactly what to do. Got it all done in less time than expected, and charged less than quoted. I highly recommend Madruga Construction."

Basement Waterproofing questions, answered by experts

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

Proper basement ventilation is very effective at reducing humidity. Without enough ventilation, your basement is prone to mold and moisture damage. Your basement should have as much natural ventilation via windows and doors as possible, and if your budget allows, you should also consider installing an ERV system to keep basement humidity levels at bay.

It depends on what caused your basement flooding, the extent of the problem, and the risk of the flood continuing. If your flood is coming from a septic system or sewer line, breathing in the sewer gasses can be dangerous, so you should vacate. If the flood occurs from an ongoing natural disaster, relocating to a safe area might be wise. If you just have a plumbing leak or rainwater coming in, you can likely stay in the house if you don’t have electrical lines down there, but make sure you call in professionals to fix the issue immediately.

If you notice standing water under the deck after rainstorms, you may need a drainage system to efficiently move this water. You do not want standing water to rest against your foundation or against support posts for the deck, as this could cause significant structural problems over time. Make sure the area has proper grading, too.

While water in your basement is unlikely to make you sick unless it’s coming from a sewage backup, mold is likely to start to grow in wet areas within 24 hours, and mold can make you sick. According to the Centers for Disease Control and Prevention (CDC), inhaling mold spores can cause allergy symptoms, including runny nose, itchy eyes, difficulty breathing, wheezing, and itchy skin. Individuals with pre-existing respiratory issues like asthma and immunocompromised individuals are at an elevated risk of symptoms when inhaling mold spores.
