Recommended Customer Reviews

Used Delta mechanical to remove my water heater and install a new gas tank heater. They called immediately on Easter Sunday to discuss my options and gave me a few different quotes, which were better than most others. They also had the best warranty by far. Fernando showed up for the job and was very courteous, professional, and knowledgeable. He got everything installed and cleaned up in a few hours. I would recommend them to anyone looking for a water heater.

We purchased four toilets and Delta mechanical was assigned to do our install. We were called within a day of purchasing the toilets and they were installed the next day by Fernando, who did all four by himself in a record amount of time. He took great care in each space, informing us along the way. We have a three-story condo, so it was a heck of a lot of work for one person, he did an amazing job. We will definitely be calling on Delta mechanical for our next installs, or any other issues we may have.

The water heater rusted through, as they all do here eventually. It happened around midnight and luckily my son was still awake and went into the garage & stepped into a pool of water. The Delta plumber did an excellent job and was very fast. He explained how to use the new water heater and the dangers. They were also the best price for a reputable company. They were here the next day and saved me a lot of headache.

Water heater repair (50 gal gas tank) coordinated through Home Depot, which contracted with Delta Mechanical for the install service. From beginning to end, the process was smooth. Delta Mechanical communicated well throughout the process. Fernando, the technician/installer, was on time, as per the service hour window. He was very professional! The installation was perfect and took only a couple hours. Highly recommend their service if ever needed! Thanks again!

They arrived at designated time. Installed a water heater (water heater $1680 installation $1764.00) ran the water line... not where it previously ran, out of the way, but very close to the washing machine....which would have been hit whenever doing laundry. When I inquired about the placement the tech said ""I only have to please the inspector"" .
They insisted on installing a pressure regulator valve (hasn't had one for 40 years that I've had the property and water company says nowhere in the entire city of IB is the water pressure above 87 lbs...that was $380 additional. The shark bite fittings they installed leaked immediately and water ran down the street (in a drought) for a week..they said they couldn't get the water shut off at the street...the water company replaced the shutoff and they came and tried to fix the leak, unsuccessfully... until the Senior Tech arrived and saved the day....he rerouted the offensive supply line to the water heater and assisted the original tech in fixing the leak. Only the Sr. Tech made this while painful process acceptable.
The water company estimates bill to be 3.5x normal.

Thank you Andrei Canale did an amazing job installing our toilet!

Our 16 year old GE water heater finally succumbed to its death and needed a replacement asap. I got it at Home Depot so why not and do it again. Online at homedepot.com I filled in the questionnaire for water heater installation quote. Just after I hit finish, immediately Delta called to assist me and and lucky enough they have an opening the following day. Our technician Cristhian was beyond expectation. He was knowledgeable and did an excellent job on the install and nice enough to do an add-on job to replace our 49 year old OG water valve with 3/4 ball valve. Thank you Cristhian!! Our family are now showered and happy :)

Everything went excellently. It was just done today- so of course something could still happen - but they were here on time, they worked very efficiently, they noted a few things I was quoted on that I didn't need and removed from final invoice, and explained everything they were doing and accurately estimated the time it would take. I would recommend to others. Very professional.

Christian was our Delta Plumber who came out and replaced our Water Heater . He was very professional . He explained everything he was doing . They have a great transparent process of all you having done . He even said it was less as the stand was not required as ours was in good shape and the straps could be re used . Installed and demonstrated how it worked / light the pilot etc. A great experience . I would not hesitate to recommend Delta and Christian is a great employee .

Delta is the company that was referred to us when we decided to go with home depot to replace our water heater, which was leaking. If it wasn't for the fact that they showed up so quickly and I needed hot water, I would have immediately found another company to work with as the technician Genadi was extremely rude from the minute he arrived at our home. He huffed about being asked to wait two minutes for us to put our dogs outside when he arrived. He was condescending and had an attitude when any question was asked about the work that was to be completed in MY home. I ended up calling my neighbor over to the house as my husband was at work, and the minute another male was there his attitude flipped to excuse me ma'am and he began using manners. None of the area was cleaned up after he left, so I did it myself, rather than have to deal with him any further. I will NEVER use this company for any future work.
