His crew arrived timely each of the 3 days, quietly and cooperatively removed the Pergo, installed the tile and cleaned up very well after each day's work. They were pleasant and also easy to work with. I was impressed with the complex cuts that had to be made and extremely pleased with the results. I can highly recommend this very professional company.

My wife selected the granite before we retained Armadillo. She was a science teacher for 35 years and the piece she selected had numerous mineral outcroppings. It is a truly unique piece. Our interview process confirmed our preference for Armadillo. He suggested Barbara come to the shop and lay out the counter with him. He would not make a cut without Barbara's approval. She did go to the shop and choose the flow of the lines and minerals in the granite. They did not miss a trick. The back splashes matched the counter top; the entire project looked as though it had been painted on a canvas. Once the meeting with Barbara was completed, the next meeting was with the general contractor. They both measured and re-measured the counter top area. They discussed matching the back splash behind the cook top with the hood vent. Also, they reviewed the support that the counter would rest on. Armadillo works well with general contractors. The owner of Armadillo is an artisan with a very practical side. One of the problems with a granite top is the installation of an under counter dish washer. It often requires screwing into the granite top. He showed us a product he brought from California. It is a strip that glues to the granite and the screws go into the strip not the granite. He also has a unique method of reinforcing large cut out areas ( cook top, sink ). The installation was as meticulous and perfect as the pre planning.

The success could not be replicated, however, despite interviews, planning, and extreme efforts on our part. Tom means well but simply lacks the necessary skills and attention to detail to act as a general contractor. Work was extremely slow because there is no crew and absolutely no materials or construction progress plan (for example, order the doors before it's time to install them). Tom works only a few hours a day, about four days a week. Subcontractors quit and had to be replaced at least once (electrical, pumbling, HVAC). That was a clue, especially when it came to light that some work was done without the required city permits or had failed city inspections. One subcontractor walked away from open permits, and no others would step in to finish the job. The only sub that didn't quit poured the concrete without ever putting a level on it. Neither did Tom, who was supposed to be acting as general contractor with the knowledge and management skills to supervise the work of others. One problem like that led to another one, all of which cost substantial sums to remedy. As another example, we were stuck with a $3,000 HVAC system that could not be returned and could not be installed (unless we wanted to risk failing another city inspection). Even framing and painting were problems. For example, one installed door simply would not lock for more than one day in a row until the new contractor discovered that the framing beneath it was incomplete. Painted doors were installed, but the top and bottom edges had not been painted. The constant delay and string of problems led to family stress and the eventual decision to cut our losses and hire another contractor to finish the job. We couldn't afford to hire that company to fix all the problems caused by Caldbeck, and we know that certain areas of framing will probably need fixing in another decade. If you ask Tom, he will tell you that we were unreasonable, but it has now come to our attention that Caldbeck is still doing work in our neighborhood without required city permits."},"url":"https://www.angi.com/companylist/us/tx/san-antonio/caldbeck-construction-reviews-6615898.htm"},"position":8},{"@type":"ListItem","item":{"@type":"LocalBusiness","name":"KEESEN LAWN SPRINKLER SERVICE, INC.","address":{"@type":"PostalAddress","addressRegion":"TX","addressCountry":"US"},"review":{"@type":"Review","author":{"@type":"Person","name":"Judy L."},"reviewBody":"The installer did a fine jpb and I commend Keeson/ Prior to this, I've used one compan to install and maintain 10 sprinkler systems in the past.

Frank is awesome. We discussed over the phone at length, and he was able to make a guesstimate at that time. He came out promptly the next morning and looked things over. Seeing that it was going to be a difficult (two-man) install, due to space constraints, he strongly urged me to reach out...

FAQs for generator install projects in San Antonio, TX
When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.
Installing a whole-house generator costs about $5,000 on average. Prices range from $1,550 to $8,500, depending on size, brand, fuel type, and assembly. The size of your whole-house generator is the most significant cost factor, with large homes with high energy demands costing the most to power.
Types of whole-home generators include:
Portable generators with 1kW–7.5kW capacity: $500–$2,000
Partial generators with 9kW–20kW capacity: $2,000–$6,300
Whole-house generators with 22kW–48kW: $5,000–$18,000
When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together.
Check out the wattage of these essential appliances:
Refrigerator: 600 watts
Large dehumidifier: 700 watts
Large window air conditioner: 1,400 watts
Water heater: 3,000 watts
Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running.
Here’s what you can run with different wattages and types of generators:
Portable generator:
2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers.
4,000 watts will keep two large appliances operating and a few smaller devices.
8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.
Partial to whole-house generator:
20,000 watts and above will make it seem like your home’s power is still on.
The value of installing a whole-house generator is that your home has guaranteed power, even if the power grid in your area is down. Whether a whole-house generator is worth installing in your home depends on how often you use it, your home’s location, and your lifestyle. For example, installing a whole-house generator is likely worth it if you:
Experience frequent or prolonged power outages
Work from home
Store a lot of cold food
Have a sump pump
Have a pump for well water
Use electronic medical devices
Live in a climate requiring heating or cooling
