"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."

"We worked with Ali (sales manager) and Tony (project manager), who took the time to design a project that made sense for our property and our budget, made a number of suggestions and recommendations and were never pushy or tried to "sell" us on something. The crew really went above and beyond to provide top quality workmanship and overall we were in very good hands. Highly recommended!"

"Integrity waterproofed the roof of my floating house to create large deck space and some months later waterproofed the new decks around my house, both times using an epoxy based product called Deck 70. They are easy to work with, very pleasant to have around the house, and do top quality work. I cannot praise them highly enough. Top notch people doing top notch work."

"The company called us the day after the earthquake, offering to come and do a free check in the crawlspace to be sure there is no damage or places needing repair in the liner after the quake. I phoned them yesterday to make the appointment and they came out today. And there is no damage or repairs needed, and the liner held up, still attached to the foundation cement stones and pillars. I felt this was very thoughtful of them to remember us. Since we installed the product a year ago, they have helped us feel comfortable that the product is doing what it is supposed to do. They also came out during the rains (however brief) in late February and checked that everything was still dry (not that we had flooding or ground water tables rise, but we were concerned that rain might have been coming in from the side vents in the house siding to the crawlspace). It was dry and everything looked good, so we determined that no more work was necessary to close up the house's side vents. That was money and time saved. ...Professional company and good people.

"Extreme makeovers was great to work with.  He was always prompt with either phone calls or arriving at my house to do the work.  Staff was courteous and cleaned up when finished.  Extreme kept to the budget and there were no surprises."

"Very professional and polite people. The foreman of the two-man team saved our deck from collapse, after a support had rotted out. The price was exactly as estimated (though somewhat higher than I'd originally hoped), they came within a week, the job was completed in one day, and they tidied up nicely after they had finished."

Basement Waterproofing questions, answered by experts

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

Yes, you can technically make a crawl space liveable, but the only way to do so is by converting it into a basement. While some crawl spaces are big enough to walk through and store large items, they lack appropriate insulation and space to be liveable.

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.

Preventative measures, such as maintaining drainage systems, installing sump pumps, inspecting roofs regularly, and crafting comprehensive emergency plans, can help mitigate future risks.

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you.
