R.S. Andrews provides plumbing, HVAC, and electrical services throughout Lithonia and the surrounding DeKalb County area. From neighborhoods near Arabia Mountain to communities along the South River, service is available across the full area.

Lithonia’s name reflects its defining feature: large granite formations that shape much of the local landscape. Unlike areas dominated by softer soil, this underlying rock creates a more rigid ground environment, influencing how properties interact with moisture, drainage, and seasonal changes.

Because granite does not absorb water in the same way as clay, rainfall often moves differently across properties in the area. This can lead to varying moisture patterns around foundations and below-grade structures, especially during extended periods of rain.

Environmental Stressors in the DeKalb Canopy

In addition to the underlying rock, Lithonia is known for its dense tree canopy and natural terrain. Shaded lots often retain moisture longer, while root systems and organic debris contribute to changing ground and surface conditions over time.

Seasonal weather also plays a role. Summers bring sustained heat and humidity, while winter can introduce quick temperature shifts. These changes affect how materials expand and contract, particularly in homes exposed to both direct sun and shaded conditions.

  • Rock Formations: Shallow granite and shelf rock can influence drainage patterns and how water moves across a property.

  • Tree Coverage: Mature trees contribute to shading, moisture retention, and root interaction with the surrounding ground.

  • Temperature Swings: Rapid shifts between heat and cold create ongoing expansion and contraction across materials.

  • Pollen and Debris: High seasonal particulate levels are common due to the surrounding vegetation.

These environmental factors vary across Lithonia depending on elevation, tree density, and proximity to natural features like Arabia Mountain. Homes in more wooded or rocky areas often experience different conditions than those in more developed parts of the city, shaping how properties respond throughout the year.

Localized Solutions for Lithonia Homeowners

R.S. Andrews is fully active within the Lithonia community, providing the technical expertise necessary to navigate these regional hurdles. We understand that a standard fix isn’t enough when dealing with the unique geological and climatic pressures of DeKalb County. Our team is available to ensure your home remains a reliable sanctuary throughout the year.

  • Electrical: Storm activity and a mix of older and newer construction influence electrical usage and demand across the area.

  • Plumbing: Lithonia’s rocky terrain and local water mineral content influence how piping systems perform across different properties.

  • Air Conditioning: High humidity levels and dense tree coverage contribute to increased cooling demand in many Lithonia neighborhoods.

  • Heating: Winter temperature swings across the granite-heavy landscape create varying heating patterns from one property to another.

Each of these systems plays a vital role in maintaining the integrity of your property. By focusing on the intersection of modern technology and local environmental demands, we help Lithonia residents avoid the common pitfalls of our unique location. Professional oversight ensures that your home’s vital systems are prepared for the specific stresses of the “City of Granite.”

I had RS Andrews come out to address several electrical items that were identified during the inspection when selling my home, and I couldn't be happier with the service I received.
My technician, Zac, was outstanding. He took the time to explain everything he was doing and, more importantly, why it needed to be done.
Zac not only completed all of the required inspection repairs, including installing GFCI protection where required by code both inside and outside the house, but he also identified and corrected a few additional electrical issues that were related to the inspection items.
He was professional, knowledgeable, courteous, and took pride in his work from start to finish. It's not often you find a technician who combines technical expertise with excellent customer service, but Zac certainly does.
I highly recommend RS Andrews, and if you have the opportunity to request Zac, I would do so without hesitation. He made what could have been a stressful part of selling a home a very positive experience.

My wife and I are elderly, and summer nights without air conditioning is almost unbearable. Our air went out at night, on July 1, and we called RS Andrews. They sent a very pleasant, knowledgeable young man out, and he repaired our system in short order. We were very pleased with both the repair service and the price. If you have work to be done, you can call Andrews 24/7, and expect quality service at a reasonable price.

I had another leak in my basement bathroom and RSAndrews came out the same day to repair and replace some pipes. Their professionalism from the time I called “How can I brighten your smile “ was so impressive and amazing. The plumber was so informative. I was so happy I used RS Andrews instead of my home warranty Choice Homes

The install was a complete furnace and AC unit. From the estimate to the install everything was done as promised and timely. There was initially some confusion regarding my thermostat but that was resolved and taken care of. Update 11/18/22 Chris is great! He's been here before and is very professional and knowledgeable. He took the time to diagnose an issue we've had and is working to resolve it 11/28 Chris is still great they are still finding issues and resolving them as quickly as possible. 5/9/23 Bill and his son came to move a gas line for a new stove.

Kalvin was great! He was very professional while explaining future tune ups and code requirements. I believe my present unit is approximately 16 years old and perhaps sometime in the near future best think about replacing the unit altogether. Good information to have, I'll keep Kalvin's recommendation under consideration.

RS Andrews did an excellent job and helped improve my air quality with an ultraviolet light in the downstairs furnace. I had previously had one installed upstairs and after 8 years, no mold. but after seeing the mold that accumulated downstairs RS Andrews Installed an ultraviolet light in that furnace system. Well worth the investment!

Charles was very professional and efficient. Very knowledgeable. The toilet was $217.00 and the cost of the plumbing was $489.00. I tipped him $60.00. The toilet is very wobbly and they’ll have to comeback and place some plastic or rubber shins beneath it to balance it!!! This shouldve been done upon the first visit!!!

    Heater on the fritz? Frustrated with plumbing problems? R.S. Andrews is just a call away!
