"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."

"They were okay. I had an upstairs bathtub and it was leaking a lot and they fixed it. They put a steel mesh around the tub so that the rodents couldn't get to it. He went above and beyond. I am satisfied with his work. He is very communicative, explains things, tells you what he did and what he found."

"Greg was a pleasure to work with. Our back splash went all the way up to the ceiling and around bay windows. It was a big job. He also helped me come up with a solution to frame my kitchen windows since the sill had already been cut from the slab and installed by a previous contractor. My cousin who is a retired contractor came over and said Greg’s work was impeccable. Highly recommend!"

Basement Waterproofing questions, answered by experts

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. 

Interlocking garage tiles made with PVC are the most effective for garages with past issues of humidity and flooding because damp concrete is not suitable for paint. Epoxy coating is also water-resistant and can prevent mold buildup. Finally, porcelain tiles are a wonderful option for wet conditions if your budget allows.

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

Since basements are prone to water and moisture issues and the resulting problems can be expensive to repair and potentially damaging to your home, basement waterproofing is almost always worthwhile. Even for homes that haven’t experienced water infiltration, waterproofing the basement is insurance against facing expensive repair bills in the future. All basements will leak at some point, so fixing drainage issues and taking steps to prevent moisture and water infiltration is wise.

Installing storm windows can protect your home’s interior from heavy storms. Most storm windows are made with enamel-coated aluminum with screens and sliding glass panels. They also make your house more energy-efficient. The average storm window cost is $12,000, ranging between $4,250 and $19,850, depending on mounting, window types, glass types, and frame materials.
