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."

We design and build custom outdoor living spaces in natural wood, low maintenance materials, natural stone, and concrete pavers. We're fully licensed and insured. We have been in business since 1989 and have thousands of satisfied customers throughout the DC Metro Area. We are A+ Rated with the BBB and have won Angie's List Super Service Award for 6 years in a row. We do not offer staining, sealing, and cleaning services.

"I'm absolutely thrilled with the work Sean and his crew did on our screened porch. I'm fairly particular and wanted to be involved in the project, probably more than most clients, and Sean worked with me throughout to get the porch I wanted. He was communicative and explained pros/cons of all the various options. Partway through the project, we realized our pre-existing front porch needed some repairs too, and Sean seamlessly added that to the project and was very reasonable on the price. Once the team started, the work went quickly but was clearly done very carefully. The attention to detail was fantastic, and the end result is a beautiful and functional porch that we're thrilled with. In the first week after the porch was completed, at least 6-8 different sets of neighbors stopped us to say it looked great. I would absolutely use American Deck again for a similar project and have recommended them to friends."

I started Straka Contracting over a decade ago in Howard County after having gained considerable experience in all areas of home improvement. Much of that know-how came from working with my father who has been in the trade since the 1960s. Today we serve the central Maryland area with a full array of services including remodeling, additions, decks, fencing, roofing, skylights, siding, windows, doors, gutters and gutter guards. Straka Contracting is dedicated to quality work and we offer a guarantee to back it up on every job. What’s more, when I take on work I am personally involved from beginning to end, making sure things are done properly. Karel Straka, Owner Straka Contracting

"Karel Straka has helped me on and off with construction items on my townhouse for almost twenty years, making major changes to my deck and patio among other things. I find him easy to work with, very thorough, trusty-worthy, reliable and affordable. Sometimes I submit my own design, and he always does it better."

JWHI provides world-class customer service with consistent and superior workmanship. We strive to be the trusted market leader in the home improvement industry. Proudly, we are Super Service Award Winner for over a decade, and we plan to keep that streak going! Contact us today to discuss your next handyman or remodeling project. Our mission is to provide you with a happy home improvement experience!

"Thomas M was an excellent technician and did great work fixing all the basement windows around the house. These windows are difficult to find a replacement but he was able to repair and repaint them. The other technician was Pablo He worked on caulking all the windows around the house and he did some filling work on the garage sliding doors You did a good job, but Pablo left his trash around and didn’t pick up after himself so Thomas M and I did that on the third day. It took three days total, but it was two men for two days and one man for a 3/4 of a day actually. Although I’ll probably get charged for a full day, since it went past noon. The labor portion is the most expensive and a little higher than I initially anticipated. So, I was hoping for a quicker turnaround, but overall quality work was completed. I would highly recommend Thomas M as a technician to do future work. He’s very knowledgeable, friendly and does a great job. I would hire again but include more details in the contract language."

FAQs for swimming pool heaters installation and replacement projects in Gaithersburg, MD

Yes, you can add a heater to an existing pool. A pro can retrofit a heater to nearly any in-ground or above-ground pool. Adding a heater allows you to start the swim season earlier, finish it later, and maintain a steady water temperature in between. Many owners schedule the job during a larger pool upgrade, but it also works as a standalone project. Professional installation ties the new unit into the existing pump and plumbing for safe, efficient operation.

Most owners switch the heater on a day or two before they plan to swim, then shut it down afterward. Reaching the target temperature can take 24 to 72 hours, depending on pool size and outdoor conditions. Using a cover while the heater is off helps hold the heat and keeps energy costs in check.

Pool heaters can freeze if left exposed to extreme conditions. Freezing can damage internal heater components, potentially leading to costly pool repairs. Cycling water, covering the heater, and regular maintenance help prevent freezing. Sealing or winterizing your heater also protects it during the season—this involves draining water from the heater and its components.

Pool heaters operate with lifespans spanning from seven to 30 years. Gas and propane models last seven to 12 years, while electric and solar heaters perform efficiently for up to 30 years. Consistent professional maintenance and routine inspections extend the heater’s life and improve its performance, ensuring a safe and reliable heating system for your pool.

Before hiring a pool heater installation contractor, conduct thorough research by reviewing online feedback and gathering recommendations from trusted sources. Contact multiple professionals to discuss pricing, request references, and understand the complete installation process. This careful evaluation ensures you select a qualified contractor who delivers high-quality service and a successful installation.
