"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 FAQs, answered by experts

Water damage to concrete is often gradual and can take months, if not years, for a concrete structure to be fully destroyed. The process often starts with cracks on the surface, followed by sinking slabs and eventually crumbling cement. Therefore, it is important to repair minor damages early to prevent the situation from worsening.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.

Yes, it’s worth it to repair a crawl space foundation, even if the issue seems relatively minor. Foundation problems often get worse and more expensive to fix if you leave them untreated. Additionally, your entire home, from the framing and flooring to the roof system, relies on the foundation for even and level support. Issues with your foundation will almost always manifest as problems in and above your living space, so it’s important to find a solution.

Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.

Brick is designed to absorb moisture, but it is also designed to let it evaporate as well. So in general, the goal shouldn’t necessarily be keeping moisture out but making sure it has the room to breathe. If you have excess moisture getting through your brick wall, it’s more likely that you have a crack or other issue at play that a typical sealant won’t fix. So, instead of investing in sealant, try repairing your brick wall instead.
