"This is the second big project we've done with REO Service Pro. They finished our basement a few years ago. Both projects were done with quality and professionalism. Gary is very easy to work with. He listens and offers suggestions when needed or appropriate. I also used an interior designer with whom he worked with ease. We had an aggressive time frame for this project and it was met. Our two favorite things about working with Gary and his crew are 1) their quickness in responsiveness and 2) quality control. On multiple occasions I witnessed Gary instructing a crew member to "rip it out and start all over". In our experience with house projects, that is a rarity. Most contractors are okay with mediocre work to save time and effort. As a result, the end product was great. In terms of cost, they may not be your cheapest bid but they won't be your most expensive either. The investment is worth it. I highly recommend REO Service Pro."

"James Matthews was the John C. Flood plumber that responded to my call for water leakage from the kitchen faucet. He quickly located the source of the water leak and repaired it quickly. The cold water supply line valve had locked up and couldn't be turned off, so James quickly replaced the old dial valve with a 1/4 turn valve (which had already been done for the supply lines for the dishwater and hot water). In and out in quick order and cleaned up all debris. Very personable, too."

"Very impressed with this group. The estimator was knowledgeable and gave a very fair price, half as much as another estimate. The carpenter was skilled, neat, and communicated well, cared about our satisfaction. The scheduler is friendly and very good at reminders when they are coming. They replaced several sections of paneling in the basement and reattached the old trim which was tricky, matched and provided the panels, They even returned to fix something my husband had installed wrong. Highest recommendation of any outfit I've worked with."

"I had them do a large master bathroom, with everything replaced. They tore up all the tile, including the tile around the soaking tub (it was tiled around the lip of the tub, so elevated). The home builder installed the base cabinets before floor tiling was done, so that part of the floor (as well as the tub area) had to get elevated to the same floor level height and had to have concrete poured to match. The floor had heating installed under the tile. I had the shower wall next to the cabinets cut down to open up the shower. Tiling was perfect throughout, including grout. The drywall installed was also perfect. We had large medicine cabinets installed (formerly, a large mirror), cherry base cabinets, granite, and vessel sinks. The shower glass and granite were installed by other companies. They painted the ceiling; I painted the walls and made the stained glass windows. Lighting, toilet, shower, tub and sink faucets were installed. I would definitely hire them again!"

"We had an absolutely fantastic experience with X&M Heating and Cooling! From start to finish, Richard was beyond responsive, professional, and genuinely a pleasure to work with. You don’t always expect replacing major home systems to feel stress-free, but Richard made the whole process smooth and even enjoyable. They replaced our AC/Furnace (Condenser, Coil Pack, and Heater) as well as our hot water tank—a big job—and the crew knocked it out of the park. Everything was installed with care, attention to detail, and a clear pride in their workmanship. Richard took the time to explain what was happening every step of the way, which gave us total peace of mind. What stood out most, though, was the responsiveness. Whenever I had a question, Richard was quick to answer, patient, and genuinely friendly—it felt like working with a trusted neighbor rather than just a contractor. If you’re looking for a team that does top-notch work - don't look any further."

"Exceptional Service from JW Home Improvement – A Review Worth Writing Let me start by saying I hate writing reviews, but after the service I just received, I felt absolutely compelled to share my experience. A few days ago, that dreaded moment happened. Our garbage disposal finally gave out. With four daughters, a wife, plenty of spoons, and after years of loyal service, it had officially met its match. I had tried finding quality and trustworthy people and did what anyone would do—asked family and friends. That’s when I remembered JW Home Improvement doing my parents’ deck. They had nothing but great things to say about the experience, so I gave JW a call. After a few frustrating calls with unreliable handymen, I called JW Home Improvement and spoke with James Hinton, who promptly scheduled Jesse and Josh to come assess the situation. Thank God I did. Jesse Wertjes and Josh Metz came out, assessed the situation, and gave me three different options at varying price points. That level of transparency and choice immediately built my trust. With a full family in the house, I opted for the Cadillac of disposals, one that can apparently grind chicken bones, which feels like a necessary feature at this point. From there, Angela Redd, the project coordinator, called to schedule the installation. When our appointment day arrived, so did a snowstorm. Impressively, Angela let me know the tech was still willing to make the call. I chose to reschedule because I didn’t want anyone driving in those conditions, but the dedication spoke volumes. On the rescheduled day, Weldon Harris, the office manager, personally called me in the morning to update me that the technician, Fernando, was running a little behind due to another job taking longer. I didn’t mind at all because the communication was spot on, which to me is one of the most important aspects of good service. When Fernando arrived, he introduced himself and immediately got to work. Everything was smooth until we realized the manufacturer had provided the wrong power cord. Instead of cutting corners, Fernando ran out to Home Depot to get a heavier-duty replacement. That kind of attention to detail blew me away. And the service didn’t stop there. Janice Chuck in billing made the payment process seamless, taking care of everything right away. Later, Luis Molina even followed up to ensure the entire process had gone smoothly and asked if I’d be willing to leave a review. Absolutely. This was my first time using JW Home Improvement, but it definitely won’t be my last. I’m already scheduling an estimate with them for a bathroom remodel and kitchen cabinet revamp. If this is how well they handle a garbage disposal install, I can only imagine how smooth my remodels will go. JW Home Improvement isn’t the cheapest company I spoke to, and I didn’t pick the cheapest option, but I got exactly what I paid for. Top-tier service, communication, and quality workmanship. Highly recommend. Sincerely, Chris McCormick"

"Our house needed a number of repairs including replacing exterior wood stairs and replacing a water main shut off valve. Bobby did an excellent job on all projects and produced high quality work. We intend to hire him again for future projects."

Hello!!! I’m Alex Ruffing, welcome to my page! \n\nI’m a born & raised Northern Virginian with 19 years in construction services (and counting). I started young, with family, on area commercial jobs; Wolftrap, Metro Garages and Park & Rides, and many of our shopping plazas. Then spent some time traveling the east coast building in the industrial sector; concrete, sky rises. Now I am happy to be home and operating as a Handyman(+). \n\nHandyman because I mostly operate independently, preforming all kinds of repair and remodeling opportunities. \n(+) because I am well connected with reputable tradespeople in the area, and I always happy to discuss larger residential projects; backyard pavilions, outdoor kitchens, shotcrete pools, additions, movie theaters, bars, and wine cellars. \n\nMy cell phone is (571)320-8605. Do not hesitate to call or text so we can discuss solutions regarding your home’s next repair, remodel, or improvement. \n\nWith best wishes, thank you. I look forward to hearing from you.\n\n

FAQs for thermostat installation and replacement projects in Reston, VA

Smart thermostats may be worth it for many homeowners. They come with various features, including voice control and smartphone apps. Vacation mode can help lower energy usage when you’re out of town for an extended period. Alert warnings let you know about major spikes or drops in temperature. Smartphone apps can track energy usage, and smart thermostats can learn your routine over time to adjust your temperature and reduce wasted energy consumption automatically.

You typically do not need more than one smart thermostat. While it’s common to see multiple mechanical thermostats throughout a large home, multiple smart thermostats may try to override each other. This can lead to problems with the HVAC system. Ensure the unit you buy has the option for dual- or multi-zoned systems to avoid compatibility issues.

Installing a programmable or smart thermostat may save you $180 per year in utility costs. A big part of this comes from a smart thermostat’s ability to learn and adapt to your regular routines. With smartphone apps or web-based interfaces, you also have the option to control your thermostat when you’re not home.
