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."

"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 write this review as a sigh of relief now that our renovation project with River View is finally complete. The quality of the final work is excellent, and the construction crew, architect, and county inspector were all great to work with. The original crew we worked with, led by Edwin, were so hardworking, friendly, thorough, and fast. That's what really pushed us from 2 to 3 stars. However, the process getting here was frustrating and unnecessarily chaotic. Timeline & Communication Issues: Initial promise: We were clear that the renovation had to allow us to live in our home during construction and be completed before Christmas. Early communication: Our original project manager, Cris, was personable, and early communication seemed fine, if a bit informal and sometimes inappropriately personal. Major miscommunication: Near the holidays, we discovered that the plans submitted included cutting into the roof — something we explicitly said we didn’t want. This contradicted verbal assurances and caused major last-minute changes. Project Management Failures: Poor planning and oversight: Cris and the architect’s plan didn’t align with the construction work. We had to get involved directly with the county to fix errors. Paperwork errors: Incorrect submissions to the county added delays and confusion, which we had to monitor ourselves. Last-minute scramble: We were cleaning up dust on Christmas Eve due to these planning failures. Personnel Turnover & Lack of Handoff: Cris leaves the company: No proper handover to James, the new PM, who was unfamiliar with our project. Crew replaced: The original crew, who were great, were gone; new crew had no context or direction. James leaves: Another handoff with no context — the third PM had no idea about our project or its outstanding items. Escalation mishandled: When we raised our concerns with Kyle, the CEO, the response felt dismissive, with no accountability for the previous missteps. In summary, it's a beautiful end result... but we’re glad it’s over. The process left us frustrated, confused, and frankly, exhausted."

"We had a partial deck built for our above-ground pool, and the whole experience was excellent from start to finish. Jim the owner, was great at communicating, he went over every detail with us beforehand, and even came out in person to check on the progress to make sure it was going well. It was clear he really cared about making sure everything turned out right. Simon was the one who built the deck, and he did a beautiful job and made it look perfect. He took our ideas and brought them to life exactly how we pictured it, with great attention to detail and craftsmanship. The deck feels and looks amazing, and has completely transformed our pool area into what we wanted.

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."

"We had our master and hall baths completely gutted and rebuilt. We bid the project out to several companies, and DMV was immediately the most helpful. Pricing was very competitive. Luis and the team completed both bathrooms in about 6 weeks - and this was a full demo. The crew was extremely kind and courteous, and worked hard to minimize the mess and impact to our home. One weekend we had a party, and they helped make our home look like there wasn’t a major project in-progress! Craftsmanship was impeccable. The tile work in particular is beautiful - details I hadn’t even thought of were done for me. Like any job, we had some changes to scope (our choice), and some minor hiccups. They were extremely helpful navigating through scope changes, and more than fair on pricing. And on the minor hiccups, they made it extra clear that the job wouldn’t be wrapped until we were satisfied - and that’s what happened. Honestly this experience was a 10 out of 10, and I hope we can have them out for another project soon. Our bathrooms went from blight to bling in 6 weeks - I look forward to getting ready now!"

FAQs for swimming pool heaters installation and replacement projects in Rockville, 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.
