"We were in need to Remodel our Bathroom due to leak from the pipe in between two Bathrooms and change out the plumbing of our house from galvanized steel to copper, upgrade drain to ABS pipes. Geico Builders crew had an immediate availability to solve our issues. Mila was assigned to our project as a project manger. The communication of the project manager was outstanding as well as guidance on what has to be purchased for completing our beautiful Bathroom. Once the water leak was discovered and the subfloor damage was assessed. A repair plan was quickly in place for the leak. Plus a plan to restructure and build a stronger subfloor. Overall, Mila and Supervisor Ruiz and their team were very excellent at staying on schedule and completing the project with quality workmanship. Overall we are very happy with our beautiful new bathroom. Our renovation project was completed on time and the new look absolutely met our expectations. Our main expectations/requirements were a regular shower pan, the shower walls and the flooring, all done with quality porcelain tile. Adding a shampoo niche and 2 safety grab bars in the shower area. Plus the bench which I am so happy with. All of these items were installed with attention to detail and with quality workmanship. Thank you Geico Builders for your professionalism and hard work we are truly Happy with everything you had done to our house and looking forward to work with you for our new project which is going to be Kitchen Remodeling by next year."

"Everything looks good after the work was done. I can finally close my bathroom door. I appreciated the fact that the foreman Erick Baez, went over what was done as they were done. I also appreciated that the two installers Manny Erickson and Jesus Villagomez also communicated with me after they were done to reassure that they did a proper job installing the jacks. Very good to know how the process was going. Great job."

Basement Waterproofing questions, answered by experts

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

Basements are commonly converted into game rooms. The potential challenges you may run into include controlling moisture, working with low ceilings, limited natural light, and the need for additional electrical or HVAC work. Addressing these issues can add to the total cost, but it ensures a comfortable and functional space.

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.

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.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.
