"Our son referred us to Hague he was very satisfied with their service and I can see why. We had Hague install water purification and reverse osmosis system in our home. Brett Jordan and Dominique were very professional and courteous, they went above and beyond in the installation process and explanation of how the system works"

"Had our old tank water heater replaced with a tankless model and had a whole house water filter installed at the same time. We had only a vague idea of what we wanted when we started and they were able to help us flesh out our plans without making us feel foolish for not knowing every detail (which wildly some of the other bidders did). They were able to come out fast and did good work, would hire them again in the future."

"Excellent service! We scheduled Plumbing Plus to replace the hot and cold cartridge's in a sink faucet and a tub pop-up drain and overflow gasket. Jared N. quickly assessed the problems. The faucet was so corroded with water deposits that it could not be dismantled to simply replace the hot and cold cartridge's. So Jared replaced the entire faucet with a high quality replacement. After the tub pop-up drain was replaced, Jared checked for leaks by looking in a 'trap door' in the ceiling below the tub that was left after the tub was replaced in an earlier remodel. Jared discovered that the entire tub drain was leaking and need to be replaced, which he did. He also corrected a problem with the drain pipe left from the previous remodel. Although the job was much more complex than expected, Jared was professional, efficient, and extremely cheerful throughout . We highly recommend Jared and Plumbing Plus"

"Gabriel, the owner, promptly provided an estimate that was much higher than three others I secured. The higher cost was related to moving the furnace to the attic because the larger furnace plenum would interfere with a roof truss. Since others did not recommend moving to the attic, Gabriel offered to come back and reevaluate his proposal. By offsetting the furnace in the closet, he agreed it would fit. The new proposal was comparable to others, and included larger coolant lines. I chose him because he knew his business and explained things very well. I was convinced he would do a good job. The work was done on time and to perfection. The workers (all speaking good English) were knowledgeable, polite, friendly, hard working and they cleaned up every day. The system works great. The insulation keeps the house moderate, so the system does not work nearly as often. An asbestos abatement company had to come in ahead to remove existing asbestos. They charged $800 to remove two pieces (a flu casing and a small wall piece next to the flu). Two workers spent 1.5 hrs to do the job. I felt their price was too steep. Gabriel was able to get them to reduce their price by $200. At my request, Gabriel gave me a week after completion for payment so that I could post the payment after the credit card closing billing cycle, allowing me an extra month to gather the funds. That was nice of him, since the contract was for full payment upon completion. All in all a good experience."

Hydro jet uses water at 4,000psi to clean the inside of the mainline drain which connects all the home's drains to the city's sewer system.
Using a snake we can go through the cleanouts on the side of the house.
With the cleanouts snaked, and the blockage located, we can send the hydro jet through the sewer vent and flush out the blocked drain.

"I had an excellent experience with Pro Bright Construction. They responded to my initial inquiry very quickly and were able to schedule the installation of a whole-home water flow restrictor on the main water intake that same day. The two professionals who completed the work were friendly, knowledgeable, and courteous. Although this was a significant installation, they finished the job in just a couple of hours and left the work area spotless. I was quoted a price by a large plumbing company that was nearly twice the amount I paid, so I also appreciate Pro Bright's very fair pricing. I'm left truly happy for their prompt response, professionalism, quality workmanship, and value. I will definitely contact Pro Bright Construction for any future plumbing needs and highly recommend them."

"I contacted Anderson Plumbing Heating & Air, a honest and trustworthy company after I realized at the last minute I needed a refrigerator water line assessment and they quickly sent Miguel to my home who noticed upon assessment inspection the water pressure was unsatisfactory and recommended replacing the water pressure valve in addition to the refrigerator water line. Miguel was absolutely amazing , a breath of fresh air, very easy to work with, and managed to accommodate my water line hookup needs fitting me into his busy schedule. Miguel provided me with a great service experience at very reasonable price! He went above and beyond providing before and after pictures of my old and new water setup, answers all of my questions, all while providing outstanding customer service with a smile & 10/10 quality of work! Thank you Miguel for a great refrigerator water line hook up experience !!"

"From the introduction of the product and discussion by Alexander Hall to communicating with scheduling it was wonderful. Installation by their team was clean, thorough and they were truly knowledgeable. The unit works well with a quiet compressor and maintains a wonderfully comfortable home environment. Their follow up and service is truly very nice . I highly recommend the entire team if you are looking for an AC and Heater replacement"
