"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."

"Saturday night the drain clogged. I️ put 25’ snake down with no success. Called them 9am Sunday morning, arrived around 11. All other plumbers had no Sunday availability or would be way later in afternoon. Oleg arrived, very quickly assessed situation and got industrial snake. Took about 45 minutes (and about 35’ of snake) so clean clog. After he flushed out garbage disposal and gave some maintenance tips. Had been quoted $99 to $115 and ended up at $105. Gave my kids pens when leaving which they thought was very cool. Quick, clean, reasonable price, polite. Not much else you can ask for."

"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."

Basement Waterproofing FAQs, answered by experts

A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.

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.

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:

  • Using dehumidifiers 

  • Silicate concrete sealers

  • Vapor barriers 

  • Baseboard channels 

  • Drain tile systems

  • Waterproofing paint

  • Drainage systems

  • Epoxy injection

  • Interior French drains

  • Exterior excavation and waterproofing

  • Cement waterproofing

  • Weep tiles

  • Liquid membrane

  • Sheet membrane 

  • Yard grading

  • Gutters and downspouts

A sump pump can remove excess moisture from under a house if standing water is present. Other ways to protect your crawl space from moisture include installing a vapor barrier, using a dehumidifier, installing insulation, and using a fan to dry the space. Finally, keeping your gutters clear of debris and positioning your downspouts away from the home’s foundation can prevent moisture from getting into the crawl space in the first place.

The process might take a few days to a week, depending on the method chosen, area size, and weather conditions. Some solutions, like simple interior sealants, may require less time.
