Transform your space with Washingtonian Companies, your interior/exterior design-build team. Whether it's roofing, windows, siding, decks, kitchens, bathrooms, or additions, we are your trusted partner to bring your vision to life and help personalize your surroundings.

"We were 100% satisfied with Washingtonian and with their work building our addition and deck. Not only was the workmanship and quality of the construction outstanding, but they operated with honesty and integrity. Their goal was our satisfaction and building a quality addition and deck. They accomplished all three and were reliable, dependable and conscientious. At no time did we believe that they had over-committed or were unable to deliver on what they had promised. They never cut corners to rush to another job nor did I ever feel that they were not spending the necessary time to ensure that the work on our job was thorough and complete. Travis, Kris and their crew were 100% professional, communicative and transparent. We will be using Washingtonian again, without hesitation. Our experience was excellent and they did an awesome job."

"It is my pleasure to review DMV kitchen and bath. They did an outstanding job from conception through to the last details in finishing an extensive series of renovations - complete kitchen tear-down and renovation, master bathroom and closet teardown and renovation, two bathroom complete retiling/renovation, building two new rooms out of a very large basement, and replacing two forced air HVAC systems - they managed all aspects including proper construction permits. They did high-quality work at a very good price. They did an outstanding job with the work, with high attention to detail. Their communication was very strong from beginning to finish, their initial plan recommendations were excellent, they made several recommendations to not only make the job better, but also make it more cost effective along the way. They were reliable and consistent, and very genuine, "real" people. I have to imagine there will be very high demand for their services. I can’t recommend highly enough. Very timely, excellent communication, quick and high-quality professional work at a competitive price."

Complete kitchen and bath remodeling including plumbing and electrical. Highly experienced and certified technicians with over 20 years of field knowledge and empierce that will respect your home and delivery an amazing experience that you will remember and share with others for years to come. We can customize any project and work with any budget. You will admire and adore your new space.

"After I terminated the lease of my tenant in early 2023, I decided to do the whole house remodel before selling it because of the age of the house and TLC it needed. The original contractor I hired ended up going to jail for child abuse charges and I had to find another contractor to finish the job. I got a number of quotes and decided to go with Donna from AND Contractors, LLC. It is very difficult to come into a project that somebody else started and the quotes reflected that but Donna’s estimate was fair and I felt comfortable in my interactions with Donna. Don't let the fact that a woman runs the business fool you - she is a real tough but fair boss. She was on the job site every day! She treats her people right but also lets them know when they mess up and they respect her for it. There were many things that were not visible but needed to be redone where the original contractor messed up but it was important to Donna that the corrections be made. I am sure there must be limits but all of these corrections were accommodated without change orders. The project was completed on time and within budget. Oh, did I mention Donna is also a real estate agent? When the project was completed, she listed the house at the highest price in the history of the neighborhood. I was hoping but not expecting it so it was a pleasant surprise when she brought me a full price contract within a few days! I HIGHLY recommend AND contractors, LLC and Donna! If you want your project done right, on time and within budget, you owe it to yourself to at least have her look at your project!"

General contractor servicing Montgomery County and parts of Washington DC. Willis Builders is a family owned and operated company, that specializes in additions, kitchen, bathroom and basement remodeling. Our team is skilled in all aspects of residential construction. Willis Builders has built a business on honesty, dedication and hard work. Our goal is to make your renovation dream come true! Contact us today to schedule a free estimate.

"Willis Builders did 2 full baths & kitchen reno + laminate floor install on main level of our modest 3-story T/H (Jan-Apr ‘24). Marcelo was our PM and as many others say, his crew did not disappoint. Willis was neither the highest nor the lowest quote of several but we felt Matt Willis presented the most honest and realistic estimate for our project and he hit that nail on the head. They might say we bothered them with questions; we might say we had to nudge them a few times. We did our homework to help things move along more smoothly & they did their best to accommodate us. We purchased a bunch of stuff before choosing a contractor. No matter what we threw at them, installation was a success which is a testament to the knowledge and capabilities of Marcelo & crew (Horatio, Frankie & “George”). When we were undecided or unsure about a product, Marcelo steered us toward better or more appropriate alternatives. We had no issue, as a few others suggested, with crews leaving things clean at the end of the day. Our T/H is small with limited space for them to work/store materials & equipment. We never felt compromised during 3 months of disruption. (And we never hesitated to leave our home when work was being done.) Is everything perfect? No, there is no such thing as perfection in an almost 40-yr old house reno or any reno for that matter. There were a few glitches as we expected, but uh-ohs and problems that arose were resolved promptly. We waited to post this glowing review of our project to see if any problems showed up, and none did. Until the ceiling in our bedroom collapsed several months later which had absolutely nothing to do with their work. We are so thankful that we had no reservations about sending Matt Willis an SOS for help with our emergency. In fact, we were so confident in his work that we decided to add painting and a carpet upgrade to what has become an almost total house reno. Again, Matt’s estimates were fair and reasonable, such that our confidence in his company allowed us to forgo spending time getting quotes from others. Matt told us repeatedly how good his ‘drywall guy’ was, and he did not exaggerate! Will & sidekick Carlos were fast and fastidious! The carpet install was equally quick and painless. We are so very happy with the results of our sudden and unexpected 2nd Willis project. We're sorry we didn’t get a chance to rave about how thrilled we are with the results of our 1st until now. If you’re considering home improvements, we highly recommend you consider Willis Builders. We’re doubly happy we did!"

Tankless water heater installations FAQs

Yes, although they have a higher upfront cost compared to traditional units, tankless water heaters can be worth the investment for many homeowners. They heat water on demand, eliminating standby energy losses and leading to 24% to 34% greater energy efficiency for homes using up to 41 gallons of hot water daily. Tankless units last longer—around 20 years with proper maintenance—and require less space than traditional units. They also reduce the risk of leaks and water damage since there's no tank to corrode and fail.

Tankless water heaters, including gas-powered models, do require electricity to operate components like the ignition and control systems. This means they won't function during a power outage. If you live in an area prone to outages and want to ensure a continuous hot water supply, consider installing a battery backup system or generator to keep your tankless water heater running when the power goes out.

You should set your tankless water heater to 120 degrees Fahrenheit for optimal safety and efficiency, as recommended by the U.S. Consumer Product Safety Commission. Setting the temperature at 120 degrees prevents scalding accidents, particularly for children and the elderly, and reduces energy consumption. Temperatures above 140 degrees increase the risk of burns and promote mineral buildup, which can decrease the system's efficiency.

A 20-minute shower uses 50 to 60 gallons of water, assuming a flow rate of 2.5 to 3 gallons per minute. A typical whole-house tankless water heater can produce 4 to 8 gallons of hot water per minute, providing continuous hot water for long showers. By installing low-flow showerheads and reducing shower time, you decrease water consumption and energy costs, maximizing the efficiency of your tankless system.

With proper maintenance, a tankless water heater lasts around 20 years, significantly longer than conventional tank water heaters, which last between 8 and 12 years. Regular inspections and timely repairs can further extend its lifespan. To keep your tankless system operating efficiently, have it inspected or serviced annually and address any minor issues promptly by contacting a local tankless water heater repair service.
