We service all of Southern California including LA County, Orange County, and San Diego County. We specialize in routine maintenance and beautification such as replacing your roof, repainting your home, or replacing your windows to name just a few of the remodeling services we provide. Of course we are exceptional at what we do, and we're even better at choosing who we employ. Find no better employees to work with than Suntrust Remodeling. We found the happier our employees are, the happier our customers are, and it's something you'll feel from the moment you interact with any member of our staff.
"We have to WARN anyone thinking of using this company! It was a disaster from the very beginning. No one checks up on the crew once things begin. We had to fight every step of the way sharing photos of poor workmanship and sending text messages asking when they would be back to complete the work or come out to do the repairs. Communication was absolutely terrible. The crew did NOT know what they were to do when they arrived. Quality of work was horrible and their mission statement is not true… “We understand the importance of trust and transparency in the home renovation process. That’s why we make it our mission to provide comprehensive education and clear communication throughout every project…That’s why we go above and beyond to ensure a seamless and stress-free experience for our clients”. We have paint drips all over our cedar siding and hardscape. It took over 6 months to complete our job. We will need to find another company to repair the items they did not do correctly. Feel free to reach out to us if you’d like any more information at [email protected]. We’ve reported them to BBB and also reached out to the CA Licensing Board. We are hoping to save others from getting involved with this company and causing undo stress. DO NOT trust them!"

FAQs for water softener service projects in Signal Hill, CA
The license requirements for water softener installation depend on your location. Some municipalities require that the installer hold a plumbing license, some require a permit and an inspection, but no license for the installer, and some require a permit and a license for the installer. Regardless of the local laws in your area, it’s always a good idea to hire a licensed plumber or installer. These pros will install your system properly and have the experience to size the system appropriately. Use Angi’s state licensing tool to check your installer’s license status.
Water softeners are worth the money if you live in an area with hard water. Hard water is safe to drink, but it poses serious threats to your plumbing system. The minerals in hard water will gradually build up on the inside walls of your pipes, reducing water flow to your fixtures. The minerals can also gradually corrode your plumbing system, reduce its lifespan, and increase the risk of leaks. Hard water also makes soap and detergent less effective. Water softener systems can solve all these issues, making them a great investment.
It’s possible to install a water softener yourself, but we don’t recommend it. Water softeners require working with copper pipes and electrical wiring, neither are suitable tasks for most DIYers. Plus, working with water and electricity together is dangerous and could pose a risk to your safety. Water softeners also need to be calibrated so that they don’t make your water too soft, as soft water poses just as many risks as hard water. Overall, it’s well worth hiring a local water softener installer to place your water softener system.
The cost to install a water softener system is $1,500 on average, ranging between $200 and $6,000. The labor for water softener work typically costs between $150 and $1,000, so you can add that to your equipment costs to get an accurate total. Your price will depend on many factors, including the following:
System capacity
Home size
Water hardness levels
Type of water softener
Presence of electricity in the installation area
Local permit costs
Your water softener size is based on your total household water consumption. In most cases, you can assume the average household member will use around 75 gallons per day. Multiply that by the number of people in your home, then multiply by 10 (for the typical grains per gallon). You’ll get a number in grains that should help roughly size your water softener. However, it’s best to hire a professional to install your system and use more exact numbers, like your exact average water consumption per day and starting water hardness.
