"Excellent - Hector Cabrera’s two man crew arrived early with the Pressure Treated Pine to replace the damaged trim sections. Hector’s carpenters painted one coat on the new trim panels & let them dry. They then advanced around the 3 story Colonial and removed the damaged trim. They them prepared the area beneath and measured & installed the new trim pieces & painted each installation with another 2 coats before proceeding to the next window. Most of the windows were on the first floor, but there were 3 windows on the other 2 floors which required ladders. When all 8 windows had their damaged trim replaced and painted, the men surveyed their work to make sure the trim matched pieces that remained on the windows. They invited me to check their work and it looked great, both the carpentry and the painting. Before leaving they cleaned up the driveway and the yard so that you couldn’t tell they had been there. Very pleased with the price and the quality of the work. Would definitely use Emmaty again and they do so many other things as well."

"I needed a sump pump installed in my basement and I had no idea how to go about it. Stephen answered all of my questions (and they were numerous) and kept me informed every step of the way. I had other questions too about little things - a faucet in the kitchen, hot water heater functionality etc. and Stephen patiently and expertly answered every question I had. He beat out three other companies for sump pump install price and was neat, punctual, pleasant, and very fair. He gave me a full breakdown of the price and was completely transparent. Definitely hire again!"

"The only time I get upset with Dish is when there is a storm I lose picture for a little while because the dish gets clogged. I really like them and I would recommend them.  They are polite and they try to solve your problem over the phone so you don’t have people coming to your house all the time. I get about 200 channels."

Solar Panels questions, answered by experts

Learn about common solar blockers in your area to determine how often you should wash solar panels and the best cleaning method:

  • Soot: If you have a fireplace, soot can disperse and accumulate on the solar panels.

  • Debris, dirt, and leaves: These natural elements require light cleaning. Being close to trees or living in a desert area can cause more of these to accumulate.

  • Pollen: Areas with a high pollen count require more frequent solar panel cleaning, and sticky plant material requires a deeper cleaning.

  • Bird droppings: Bird droppings are binding and more difficult to remove. Keep this in mind if you live near a lot of surrounding trees. 

Ideally, you want to place them facing true south. This is different from what a compass shows, which is called the magnetic south. You can find true south by using an online calculator as long as you know the longitude and latitude of your property. Solar panel placement is key to maximizing the energy you generate, so this is an important step.

You can install solar panels on a flat or pitched roof, but keep in mind that they will need to rest at a 30- to 50-degree tilt for optimal sun absorption. It costs more to install solar panels on a flat roof because you will need to install a framing system and likely hire a structural engineer. If your roof has a pitch of more than 40 degrees, it may not be a good candidate for solar panels.

In most cases, yes, solar panels are well worth the investment. Going solar with your home’s energy is expensive, but, in most states, the panels will pay for themselves by reducing your electric bills. Solar panels don’t produce greenhouse gasses or other pollutants, meaning you can feel good about using this renewable energy source to power your home. Plus, installing solar panels can boost your home value, helping your profit off your next home sale.

The average homeowner needs around 22 solar panels, but the exact number depends on your monthly energy consumption. Your solar professional should size your array to offset your consumption, meaning you’ll need fewer panels if you use below-average amounts of electricity, or more than 22 if you use above-average amounts of electricity. The number of panels also depends on the output of each panel. The average is around 400 watts, but you might need more panels if you install less capable equipment. Since there are so many variables, you should have a professional size your system.
