Angel Construction is a trustworthy and hardworking company started by Luis Angel and his father Juan who have been working in this field for many years. Striving to deliver excellent services with the best pricing available, Angel Construction is your solution to home foundation needs and other repairs.

"Hired Luis for a complete foundation replacement for a home on a hill in Angelino Heights. Luis was very easy to work with from coordinating plans/permits, keeping to schedule, and scope changes along the way (LA City was a PITA). Luis was easy to talk to and his pricing was the best out of 5+ bids we got. Work involved replacing the entire footing/foundation, leveling interior floors, adding a few posts and support beams under the raised foundation, and replacing front patio cement area. Luis was always looking out for our bottom line and very efficient. Normally the type of foundation replacement we did requires multiple inspector visits but Luis knew the process well and only required one inspection after work was done, saving us a lot of money. Change orders were always handled professionally and very fair to both sides. Everything turned out great (I'm writing this review a year later). I highly recommend Angel Construction and wouldn't hesitate to hire them again."

Basement Waterproofing questions, answered by experts

No, you don’t want your crawl space to be wet because water and even moisture in the air under your home can attract insects and rodents, decrease your indoor air quality, increase your energy bills, promote mold growth, and even lead to structural damage. If you notice any signs of water or humidity in your crawl space, you should get the issues addressed immediately by contacting a professional. They can remove moisture and will know how to waterproof your basement to prevent ongoing problems.

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

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.  

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. 

Regularly inspect for leaks, repaint wood surfaces, and reinforce weak joints to prevent deterioration.
