"The gave me an early time window to show up and arrived early in that window. They had all the right equipment and supplies with them and set about the job quickly, finishing it just as I was finishing my lunch. When it turned out that the bathroom faucet needed replacing, they had a Moen replacement with them. Price seemed a bit on the steep side, but what price doesn't these days?"

"Called them and discussed problem. They quoted price and scheduled appointment. Day of appointment they came, they installed new water softener, they left. The only item(s) left behind was new water softener, not a bit of trash can be found. The installers appeared knowledgeable, efficient and friendly. Have used this company previously."

"We could not be happier with the Puronics Hydronex iGen Whole home treatment system and Micromax 7000 drinking water system provided by Orbit Water Solutions. Justin, the marketing rep who sold us the system, was very professional and accommodating. Justin took about an hour to demonstrate a series of tests which reflected to quality of our water which had more chlorine and hardness than we expected. If you have concerns for lead, Orbit standard demonstration does test for it so you will need to have a separate test done. After some negotiation, we were able to settle on a deal which got us the system and financing for the next 10 years. Orbit provides annual maintenance services on the machine and there is a lifetime warranty on parts which really assured us we were making an investment to improve our water. The best part about it is that the system travels with you. For a small fee, Orbit will pack the system up and ship it to your next home if you move which was a big selling point for us. Orbit also threw in a subscription to PureSelects soap for the next 10 years which was a nice add-on. PureSelects provides every kind of soap or cleaning product you could ask for so it will be nice not to have to purchase additional soap products in the near future. Within a couple days, the installation team came out to install the system. They arrived on time but the installation took a little bit longer than expected. Turns out our the installed garbage disposal was too large to fit with the RO unit tank under the sink. Orbit was very accommodating though. Orbit purchased a new garbage disposal and installed it free of charge which I bet many companies would not have done. I highly recommend getting the larger of the under sink tanks for the RO unit. Even with the two gallon tank, my family has used up all the water in the tank. A 1 gallon tank would just not have been enough. The water in our house has been incredible since we installed the system a few months ago. We noticed an immediate impact to our skin and hair after using it and our drinking water certainly tastes better. Best of all, we feel confident in the quality of the water we use throughout the house to keep us safe and our appliances in good condition. We highly recommend the investment in the water treatment systems through Orbit."

"I had some issues with my 10 year old furnace and started looking into issues. I used to work for Carrier as an HVAC researcher and tried to fix the issues myself. I disassembled the burner and tried to get things right. In the end, I exhausted options and gave up on repair. I called my serviceman, trying to have the furnace repaired. He recommended getting a new furnace or replacing the whole HVAC since it was more than 10 years old. My serviceman gave me a quote for a Carrier furnace, which I thought was high since I knew the price of the unit (ex-Carrier R&D engineer). That was when I decided to look around. I received three quotes after reading through reviews in google and Angie’s list. In the end, I chose ARS Manassas by virtue of their overall competitiveness. In any business, it takes two things to win a deal: trust and value. In my case, one salesperson, Cliff Allen (who I will talk about more in a minute) delivered both aspects, which made the decision easy. Since I know the HVAC system in and out, I had many detailed (and even tedious) questions, to which he answered professionally with knowledge and courtesy. He did not try to upsell anything. In fact, he recommended to check a few things for repair, even while giving quotes for me. Although I decided to get the new one in the end after trying a few more attempt for repair, Cliff earned my trust and respect in the meantime. He tried to provide an optimal solution in terms of price and performance, which was more competitive than the other two quotes. I ended up getting 16 SEER performance series furnace and AC. Cliff truly knew what he was doing during the selection process. He answered all the questions an ex-Carrier R&D engineer raised and provided several quotes for comparison, which helped me to reach a satisfactory solution in an efficient and rational manner. He never tried to upsell, clearly understanding customer’s side. To the contrary, he did his best to give me the best deal without compromising performance. His professionalism does not stop at sales. He went over all the items in the specifics of installation, meticulously jotting down any notables in the contract. I was not surprised to see the technicians, Michael and Melvin, show up on time and finish the job, following the specifics and notables that Cliff had prepared at the contract phase. They tried to make the installation smooth and went over every single item to make sure that it was done to perfection. About a month later, the town inspector came out and made sure that the unit had been properly installed. The inspector confirmed that the job was done to the standard but pointed out that it would be better to add another bracket to the outdoor unit so that it would not move around. I called ARS to inform the findings of the inspection. ARS has promptly scheduled another visit (even if they could have waited for AC checkup in the late spring) to fix the issue. This time Jeremy and Josh came out and meticulously fixed the issue. These two gentlemen really knew what they were doing. They went a lot further than just adding a bracket. The outdoor unit is so sturdily attached to the bracket now that even a hurricane would not shake the outdoor unit. My kudos to Jeremy and Josh. I will come back and write a further review in 6 months to report any issues I experience but for now, I am glad that I chose ARS Manassas for new HVAC installation. If you ever need a new HVAC near Manassas area, the choice is simple. Go for a trustworthy and knowledgeable man that would deliver the best value for your investment, Cliff Allen at ARS."

"Bill Martins Flood Crew is excellent. In December, just before Christmas, my finished rec room flooded when my sump pump failed--soaked carpet, cardboard boxes, books, furniture with sewer water. I thought I would not find anybody this time of year to help me. But I called Bill Martins from Flood Crew, and he came out right away. He looked at the basement and gave me an analysis of my damage on the spot. He was wonderful. He took care of getting detailed estimates to my insurance company and then made arrangements for me with all the needed specialists. First, I wouldn't have known where to start, and second I wouldn't have had a clue whom to call. I needed crews to remove the carpet, cut out drywall all around to dry it out, check for mold, test for asbestos, and then remove everything. And, of course, fixing the sump pump, installing flooring, putting everything back, and lots of details in between. All of this obviously can't be completed in a week or even a month. My work was not the only project that busy contractors had. My situation was far more complicated than I thought it would be. Ultimately, it took four months, which I thought was very reasonable. And the result is so beautiful--no corners cut, no putting up with mediocre results, all this for the same price and time or less than others quote. Be patient. Be flexible. Talk with Bill about the results you want. Listen to suggestions. Your results will be beyond anything you thought was possible."

FAQs for plumbing installation for a remodel or addition projects in Martinsburg, WV

Adding bathroom plumbing to a detached garage starts with the basic line installation cost of $900 to $1,300. On top of this base expense, you'll need to budget for each fixture. A toilet costs  $250 to $550, sinks cost $150 to $800, and a shower or bathtub costs $400 to $1,900. The project will also require ventilation, moisture-resistant materials, and possibly electrical work. Remember that these costs reflect only the plumbing aspects—additional construction, finishing, and permitting expenses will apply to complete a functional bathroom space.

While certain aspects of garage renovation might be suitable for DIY enthusiasts, plumbing installation requires professional expertise. Connecting to water and sewer systems demands specialized knowledge and equipment, and improper installation can result in severe water damage, code violations, and potential health hazards. Most municipalities require permits for plumbing modifications, and these often stipulate that licensed professionals must perform work. Consider limiting your involvement to simpler tasks like painting or basic finishing work.

The timeframe for adding plumbing to a detached garage spans one to three days for the actual plumbing work. However, this represents only the active installation period. The complete project timeline must account for planning, obtaining permits (which can take weeks depending on your locality), coordinating multiple contractors if needed, and addressing any unexpected challenges that arise during installation. Weather conditions can also impact excavation and outdoor connection work.

Adding plumbing to a detached garage will likely increase your property taxes. Tax assessors consider plumbing an improvement that enhances property value and functionality. The specific tax impact varies by location and project scope. Converting a garage into living space with plumbing facilities can trigger significant reassessment in many jurisdictions. Before proceeding with your project, consult your local tax assessor's office to understand the potential tax implications and factor this ongoing expense into your decision-making process.
