"Our 25-year old garbage disposal died and backed up our kitchen sink. We needed it replaced quickly. Most companies we called were 2-4 days out. “At Your Service Plumbing” was able to come out that afternoon. The technician called and said he was running ahead of schedule and would it be OK for him to come early. We were happy to accommodate him. He quoted us a price before he started the project. The price was reasonable and we gave him the OK to proceed. He replaced the garbage disposal in a reasonable amount of time and addressed our questions and concerns throughout the process. When he completed the job, he ran the new garbage disposal and it was clear that the kitchen drain was also clogged and needed to be snaked. That was likely the problem all along. He quoted us a price to snake the drain that was based on completing the project within a 1-hour timeframe. He showed us what the price would be for each additional 15-minute interval. He was very upfront with the pricing and it seemed reasonable to us, so we gave him the OK to proceed. The clock didn’t start until he actually started snaking the drain. We were not charged for his time to bring in the equipment and disconnect the plumbing. It was a very difficult process and he ended up using two different snakes to get the job accomplished, but he was successful and completed the job within the 1-hour timeframe. He worked very diligently and efficiently. We were very satisfied with the end result and will certainly call them first the next time we have a plumbing issue."

"Rocky Mountain Services has been fantastic to work with. I needed a chandelier installed and I have 13' ceilings with exposed duct work and electrical, so the quality of the job would be on full display. Everyone I dealt with at the company, from the first phone call to the electrician that did the actual install, were really professional and helpful. The actual install couldn't have gone smoother, the electrician was on-time, clean, polite, and professional. Rocky Mountain Services really went above and beyond to make sure that not only was everything technically correct, up to code, etc., but that it also looked great as well. They were so knowledgeable and I really appreciate their advice on placement, height it should hang, and so forth. I will absolutely use them again."

"On the first visit, it was a simple fix underneath the sink.  Work was completed to my satisfaction.  The second visit that week, the problem was identified, however, I made the choice to not have it fixed due to cost.  
In both cases, I was pleased with the response and evaluation of the problem(s).

"Within three weeks all of the above work was completed. ....once the job started, work went quickly. Chris, the general contractor , frequently checked on my job and sincerely wanted to know how things were going. He didn't seem rushed and updated me at every meeting. The sub-contractors Chris hired were professional, friendly, arrived on time, worked full days and inspired my confidence. Jeremy Moore installed my floors and Michael and Nathan did the other work. All three are knowledgable and creative artisans. I've been recommending Colorado Bathrooms Inc to everyone and would definitely use them again! My "old" kitchen is located in my old house, so hopefully I'll be seeing them again soon!

Sink Installation FAQs, answered by experts

Local plumbing codes and manufacturer recommendations typically dictate the minimum distance between a sink and a dishwasher. This is generally 18 to 24 inches, providing enough room for easy loading and unloading of dishes without hindering the sink's function. Maintaining this separation not only adds convenience but also reduces the chances of water damage and optimizes plumbing connections.

Install the sink between 30 inches and 34 inches away from the floor. However, this height could be adjusted accordingly for particularly tall or short residents. To accommodate wheelchair users, the vanity should leave a space underneath that is at least 29 inches tall, 30 inches wide, and 25 inches deep.

The Thanksgiving holiday period is one of the busiest times of the year for plumbers. Both Thanksgiving Day and the day after, often called Black Friday or "Brown Friday" by plumbing professionals, see a significant increase in service requests. This is because a house full of guests, large holiday meals, and unfamiliarity with the home's plumbing can lead to clogged drains, garbage disposal issues, and sewer line backups. Outside of the holidays, the busiest weekdays for plumbers are typically Monday and Tuesday, as many people discover plumbing problems over the weekend but wait to call for service. Despite the holiday, you can rest assured that many plumbers work on Thanksgiving and Black Friday to handle the surge in emergency calls.

Yes, you can install a farmhouse sink on an existing countertop—but there are some caveats. You’ll need to precisely measure. It’s best to choose a sink that’s the same dimensions as your existing sink, since your contractor won’t have to cut the countertop. Otherwise, pay close attention to the depth of your counter (the front to back measurement). You don’t want to install something that’s so big it sticks out beyond your countertop and cabinetry.

If your kitchen is flooding, first turn off the water supply and electricity before entering the room. Next, focus on immediate flood control by cleaning up any standing water with a sump pump or wet-dry vacuum to prevent long-term water damage to your home. Open your windows and run any dehumidifiers you have handy. Finally, call a professional plumber to help find the source of the flood and repair it.
