"I worked with Alpha once before, and they assisted with a second project 2 years ago which, now finally completed, I'm able to write a review about. Alpha helped with structural plans for windows in a garden level unit in order to prepare the proposal for city approval. Alpha is a big company and it took them a little while to complete everything; however I can certainly say that the engineer and contact people were knowledgeable and thorough. The plans were approved with their help and now that the unit is permitted for occupancy, the windows are a lovely attribute to the space."

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.

You should always hire a structural engineer or a professional and licensed foundation repair company for crawl space repair. These professionals will often be able to treat the symptoms of the issue as well as the underlying problem so that you don’t have ongoing damage. They’ll also often take preventative measures to stop the issue from recurring in the future.

In many cases, yes, a damp basement can be bad for your health. Not only can damp air affect your lungs, but it can promote mold growth and pest infestation. Mold spores can be dangerous to breathe in, as can waste particles from insects and rodents attracted to the moisture. Damp, moldy air can also move up into your living area. As such, it’s crucial to fix any basement moisture problems as soon as they crop up.

Mold growth is just one common sign of excess moisture in the bathroom. You may also see the paint in the room start to peel away from the walls, or that the walls remain wet for some time after you bathe.

Condensation on the windows is another sign that your bathroom has a potential moisture problem. The room itself may start to smell like mildew.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.
