"Jacob arrived promptly. We live in an older home and have a cast iron pipe that runs to the main drain area in the court. We had similar situation 12/2019. Industrial snake used and what was pulled out was heavy utility towels that we determined had been stupidly flushed down by contractors that had done work in the home. It was suggested at that time to send a camera down to be sure no other issue, but we thought we were okay after seeing the utility towles removed, water was running freely through the drain in the basement. Well, part II, we're here again 8/2020. This time clog closest to basement drain freed up quickly. Jacob suggested most efficient way is to perform a jet wash blowing any remaining debris further out from the house out of the pipe into the main drain area in the court and sending camera down to see what's up. We agreed. Camera pictures revealed scale throughout cast iron pipe with largest amount of buildup further away from the property just as pipe neared main drain area in the court. Descaling will be completed tomorrow. Could have been worse. Thankfully no tree roots or pipe fracture. The Pipe Doctor's jet wash price best compared to other plumbing companies neaby and overall cost is competitive. Although we have the descaling yet to be performed, I have no doubt based on previous performance and today's performance/outcome there will be no need for me to alter this evaluation. Quick response, competitive pricing, great customer service. I would highly recommend."

"WOW!!!  From the initial contact via email we were provided with a detailed answer to every question we asked by Jake's wife, Dawn.  She gave us a price for what we wanted done immediately and that price didn't change after the work was done.  We knew the exact name and model number of the filter we were getting before we even set up the appointment.  We were given the price that included the filter and installation.  We shopped around and did further research for a couple of weeks before deciding to get the work done.  We contacted Dawn again and she was super helpful and provided the phone number that we needed to speak with Yolanda to get added to Jake's schedule.  Yolanda was very professional and worked with me to find a date that worked with Jake's schedule and ours.  We knew that they take pride in their company just from our initial contact and setting up our appointment.  Our appointment was scheduled and Jake arrived between the one hour time frame we were given.  He was polite, professional, and very helpful.  Jake installed our whole house filter and cleaned up everything.  His work is very neat and professional.  Jake took time after installing to go over everything we needed to know about the filter as we took notes.  He also let us know that if we had any questions in the future that we could call him or email Dawn.  I honestly feel that he truly meant that and would be more than willing to answer any question that came up later.  We definitely found the best plumbing service!  Jake takes pride in his work and it shows in the business that he runs.  We will definitely use A-Master Plumbing for our next project.

"The Casco Plumbing company is always the best choice for all of my plumbing needs. I highly recommend anyone with a need for a professional plumbing job, call Casco Plumbing FIRST. Replacing the aging copper pipe in my home has been on my to-do list. I had, on a previous visit by Casco plumbing, discussed the options for repair with Matt. Leaks popped up at 2 different times during the first 2 weeks of July 2018. The first leak appeared and Jason and Mark came to the house and did a great job repairing that leak. When the second leak appeared Matt and Mark responded and at that time, after consulting with Matt again, did a complete overhall of my upstairs plumbing. These are very professional and congenial plumbers and my family and I are very grateful for their kind assistance and dedication to a job well done. Thank you, Casco Plumbing!! Sincerely, NTP"

"Shaun at Dean plumbing was very easy to work with. He is very responsive and attentive, my well was back up and running in just a few hours! Not only did he replace my Well pump he diagnosed my entire system which I’m glad he does because my pressure tank was going bad aswell. Shaun explains his work and what he thinks is best for your situation. From time of call to him being at my house for service was less than 24 hours!! Highly recommend this company for all your plumbing needs!!!"

"We were in a bind and needed a previously installed granite countertop in the kitchen modified. We had a new refrigerator, and the door wouldn't open all the way back, bumping against the door jam. We needed to have the granite cut back about an inch to remedy the problem ( slide the refrigerator over a little). The problem was, we were having a new tile backsplash installed the following day, and needed the granite cut before starting that job. I called Granite Vision, and asked them if they could perform it the same day. They were unsure if they could fit it in the same day, but told me they would check on the possibility.  I was called back in a timely manner, and told that they could do it for me.  David arrived within a few hours of my call, and did a beautiful job.  He was very nice, neat, and did exactly what we needed. Thank you Granite Vision!!!  They could have just blown me off, and said they couldn't do this the same day as my call, but they didn't"

"In February I purchased a " $49 for a Plumbing Service Call and 1 Hour of Labor" from Angie's List.
I am giving a "B" rating because of the price, and because the plumber did not have the quarter-turn shut-off valves in the truck.
When I called for an appointment, the lady was very courteous and provided me with an appointment the following day, which pleasantly surprised me  The technician called before he came and arrived within the scheduled time frame.  Upon shutting off the valves to replace the faucet, he noticed that one of the shut-off valves was leaking.  We decided to have both valves replaced to prevent problems in the near future with the valve that was not leaking at this time.  He quoted us a price to replace the valves which was high, because about six months ago we had gotten a quote for valve replacement  that was much lower per valve (we had been thinking about replacing valves at several sinks.  We wanted the newer quarter-turn kind).  Since he was here, we decided to have the valves replaced.  We wanted  quarter-turn valves.  It turns out he had to replace the valves with the same kind we already have because he didn't have the quarter-turn ones in his truck.  One would think that a plumbing company would stock quarter-turn valves in their truck.  They are readily available-any Home Depot or Lowe's has a ready supply.

FAQs for plumbing installation for a remodel or addition projects in Markham, VA

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.
