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."

We accept most major credit cards and offer financing for qualified clients. Our highest priority is customer satisfaciton.

"Do NOT use these guys! They are terrible. Hugo has abandoned my project, and we are about to begin the litigation them. Hugo is a terrible communicator to his clients and employees. The pool itself looks amazing (My wife and I designed it, not them). And the work, for the most part, was good! But there are things to finish (Correct the panel location, set up the pool panel and programming, set up our app on our phones to control the panel, pass gas test and final inspection) that he did not complete after daily messaging. Pool project started on 10/3/17...we signed a contract agreeing to 90days (Jan 3, 2018)...well here we are, April 25, 2018 with out the entire project completed. Hugo showed up yesterday (4/24/18) since is was the last day for him to complete the project before he breached it, and it was the first time he actually SAW THE POOL, and it was the first time that he has set foot here since November 14th, 2017, which also happens to be the last time he collected a check!! (weird, right?!) Over 5 months ago!!!!! He'll tell you that his crew showing up for the first time in over 8-weeks is his company “continuing to work on your property”. It's the second time his company disappeared for over 2 months during this project. All the problems we had here were directly from Hugo not being here and it was on me to do his job and make sure his employees he sent did the right thing. Perfect set-up for him, Right?! Here you are, paying him tens of thousands of dollars for a project he agreed to, and you end up having to hound him and beg him to finish it! He's unapologetic about everything. There were only 2-3 inspections that I wasn't here alone to do. That's not what i signed up for! I paid full price, I paid every time I was supposed to, and now I'm the one who has to sit and wait for the inspection?! In fact, today we failed our final inspection (for the 3rd time) because we failed the gas test, and the location of the pool panel isnt to code, and some of the pool equipment will have to be moved to provide the required "working space" around our main electrical panel. We'll we have a new contractor that will finish this up. And we'll do everything we can legally to collect what is owed to us by Hugo and his company. Word of advice: Make sure that final payment in the contract is AT LEAST 20% or more...or you wont see your project finished...for sure not by these guys. But the best advice would be DON'T USE THESE GUYS!"

Unlike other pest control companies we don’t just treat the immediate structure of your home. We treat the surrounding areas including your landscape throughout the year for maximum results. Experience, knowledge, and dedication is a powerful combination in any business. When Corky started his company back in 1967 he was one of the only pest control companies in town. For the last 50 years he has had the pleasure of servicing Southern California and making it his passion to not only study the uniqueness of our climate and terrain but he has also become a well known author of the industry.

"Termite Fumigation Disaster using Corky’s Pest Control. Our neighbor and I employed Corky’s Pest Control to fumigate our attached homes. We were left with over 220 broken roof tiles and a repair cost that exceeded $4,000. That was more than the cost of the fumigation. Our HOA property manager expressed that this was an exceedingly high number of broken tiles for our community. As you can guess, I cannot recommend using Corky’s Pest Control."

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Signal Hill, CA

The most affordable way to waterproof your basement is with interior methods like waterproof paint, costing between $1 and $8 per square foot, or silicate concrete sealers priced at $4 to $6 per square foot. However, these solutions are only suitable for certain issues. If your basement moisture is due to more serious problems like a cracked foundation, you'll need more extensive (and costly) repairs.

Absolutely! Waterproofing your basement is a smart investment that can increase your home's value. By keeping your basement dry and free of moisture problems, you protect your home's structural integrity and make it more appealing to potential buyers. Plus, taking proactive measures now can prevent costly water damage repairs down the line.

The time required to waterproof a basement depends on the selected method. Some approaches to interior waterproofing, like paint or sealant, can be completed within a day. Installing new drains or weeping tiles will need at least two to three days of labor. Any forms of exterior waterproofing that require you to excavate land will require an additional three days of work to prepare the ground.

Yes, basement waterproofing can significantly increase your home's value. A dry, leak-free basement is a strong selling point for potential buyers, enhancing your property's desirability and market price. Investing in professional waterproofing not only protects your home's structural integrity but also ensures a healthier living environment by preventing mold and mildew growth.

Waterproofing both the interior and exterior of your basement offers the best protection against moisture. Exterior waterproofing stops water from penetrating your foundation, while interior methods manage any moisture that does enter. If you must choose one, exterior waterproofing is generally more effective, as it prevents water from reaching your home's interior in the first place.
