"Erinn was my initial contact and he gave a very through and fair estimate. We had structural work done to support floor joists and large beams under the garage that needed replacing. Ernesto and his team, Julio, Salvatore and Gilder worked tirelessly to complete the work and were respectful, punctual, informative and good humoured throughout the entire process. I would not hesitate to use them again or recommend them to others. A really great company!!"

"These guys were unbelievable! It sounds simple to run a water line from the street to the house but it wasn’t. Imagine almost 200 feet and hand dig uphill most of the way and across the yard. Now imagine having to go under a driveway, sidewalk and two concrete flower rails. Now add in they did it through one of the hottest heat waves Southern California had this year! I’m telling you these guys did it with sweat and a smile. Just unbelievable!"

"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!"

"Joseph is amazing. We have used him many times for years for multiple home projects including remodeling a bathroom, new siding on the house, new roofing, plumbing repairs (and emergencies). He has always responded quickly, his work has been excellent, the site is always left immaculate, his crew are always on time and very pleasant. Joseph's work is outstanding and we have never had any issues. He has helped us out fixing issues that predated him also promptly and done to only his high standards. We can not recommend him high enough and will use him for many years to come."

Basement Waterproofing questions, answered by experts

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

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.

Yes, you can enclose your crawl space. Enclosing your crawl space can promote energy efficiency and reduce the risks of pests and mold by limiting factors like humidity. It can also reduce heat loss, which is why doing so for the winter can make your home more comfortable.
