"There's so much that can be said. We hired this company to replace/install SPC vinyl plank flooring throughout our house. The sales presentation, warranties, credentials, and all sounded exquisite. What followed couldn't have been further from what was presented. Do not get fooled by this company. You will regret it and have a house undone months later. Examples include, 1) adhesive that wasn't removed immediately is left all over our floor and can no longer be removed, 2) lippages throughout the 1st floor, because they didn't properly level more than one area (imperative as the flooring is a drop-lock system), 3) a destroyed lifted joint cause by an attempt to clean adhesive 4) damaged kitchen shoe moulding, 5) adhesive/caulking stains on our siding. One of the horrible adhesive stain realities is all over our stairs, and even Rapid Restoration admitted most of the stairs need to be redone. 3 large areas of the 1st story need to be redone is another example. I was informed by workers and sometimes the owner about inner company turmoil that caused some of the delays throughout the time they were at our home. As a result, the job was rushed and the main worker stressed as he did not have much help. Those who helped a little would then mess things up that he would then have to redo. The owner is not at all engaged in the day to day business. He and his guys will tell you more than once, "The workers are on their way," and they never show up. He will also pretend like he's waiting on you sometimes, but it's all a ruse to make an excuse to further delay follow up. All we want is our flooring complete and not feel like our new home that we bought 1.5 years ago is in a perpetual state of being undone. I can't see how this company would ever be recommended by any referral service. They're nothing but a liability. Beware of Edward Gonzaba and any company he's associated with...as I can see Rapid Restoration going the same route as he previous company, The FloorSource. To court, shut down, and probably bankrupt."

FAQs for water heater service projects in San Antonio, TX
The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.
Tankless water heaters are more expensive than those with a storage tank, but they come with some impressive benefits that most homeowners find worth the higher investment. Most importantly, they provide unlimited hot water, so you’ll never run out like you would with a storage tank. Tankless heaters are also more efficient, so comparing gallon-for-gallon, you’ll spend less on hot water with a tankless heater. Tankless water heaters are also smaller, require less maintenance, and tend to last longer than storage tank water heaters.
It usually takes a professional water heater installer between two and three hours to remove an existing water heater and install a new tank heater. However, it could take four to five hours if they have to work in a small utility closet or another tight area, like a crawl space. Tankless water heaters have a more complicated installation process, so they will take a bit longer. Additionally, a gas water heater requires a connection to a gas line, and that alone can add about an hour to the installation timeline compared to installing an electric water heater.
It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.
In most municipalities, a license is not mandatory for water heater installation or replacement. However, we strongly recommend hiring a licensed plumber or water heater installer to handle the work. Licensed installers are far less likely to make a mistake during the installation, which means paying for the experience decreases your risk of a leak and other issues. You can use our state licensing tool to find out if a contractor you’re considering in your area holds a plumber’s license.
