Your Home Town Professional! The 1-800-PLUMBER® + Air history has a unique journey that laid a foundation for the strongest brand within the industry. In 1999, the 1-800-PLUMBER® name and phone number was secured, leading to the well-known “Our Name is Our Number!” slogan. In 2010, Mark Collins joined the 1-800-PLUMBER® brand as a franchisee and then in April 2015, they purchased the 1-800-PLUMBER® brand and created the foundation needed to grow 1-800-PLUMBER® into a household name throughout the country. Today, 1-800-PLUMBER® + Air locations can be found across the US, and our franchisees strive to make us the highest-quality brand in the industry through honesty and integrity, professionalism, and craftsmanship. Our teams achieve this by doing what they say they will, always telling the truth, training their team members to always conduct themselves in a professional manner, and only utilizing skilled craftsmen within the industry

"Response time was great, received a call with next-day scheduling within minutes of submitting a booking request on their website. Jacob inspected my old heater and provided several estimates for different scenarios, and had Jesus with the work completed the same day. When I discovered that night that sediment had clogged the hot water faucet in one of my bathrooms, Jacob came out the next day and replaced the cartridge under warranty. Jacob and Jesus were both courteous and communicated clearly. I would do business with this company again."

Honest Plumbing & Air has been providing the best in HVAC and plumbing services to residents across Central Texas. Above all, we operate on the belief that honesty is the best policy. We will take the time to properly assess your specific situation and we will not overcharge you for unnecessary work. You can rest assured that when you call Honest Plumbing & Air, you're getting a professional technician who will be straightforward with you every step of the way. Our team will effectively diagnose your air conditioning, heating, or plumbing problem, without exaggerating the truth.

"Beware! not so honest. I had a air conditioner that would not start earlier this year and while he was here, I asked about having some general maintenance completed at the same time. I was told it could not be done at that time but the tech suggested that I purchase a maint. package that they would come out twice a year to do general maintenance on the units. He stated that they could do in a week or so, it turned out to be over 1-1/2 months for the 1st maintenance but I should clarify that it really isn't much maintenance but a opportunity to pay them to do a quote for additional work. In addition to this, one of our units was not operational arrived, before he would even move a finger I was required to sign a document for work in the amount of around $340 which ended up taking the technician 15 minutes to replace a blown fuse and loose wire, they charged $116.99 for the fuse (cost $0.1469). Not so honest, much different story from when I initially used them several years ago. "

Alter Construction offers estimates, proposals, design services, home improvement, remodeling services, home modifications, custom homes, general construction services in Austin, Texas and adjacent areas. We are a full service construction company. With years of experience we saw the lack of customer service and proper execution for new builds and remodeling projects. For that reason, our specialized team is dedicated to providing families with responsive, clear communication. We guarantee an outstanding customer service experience. Whether you need a kitchen remodel, a bathroom remodel, a room addition, or home modifications for elderly or disabled residents, Alter Construction will complete your project with responsive communication, to your satisfaction, and on time.

"My husband already left a review for our project, but I wanted to add some additional praise. Alter Construction did an absolutely wonderful job replacing our floors and I highly recommend them! Communication: One of the first things you'll notice with Eli and his team is the tremendous amount of communication. He'll talk you through everything, provide recommendations as necessary, and answer any questions. On top of that, Eli sent us multiple updates every day that we were out of the house to keep us aware of what was happening. Pictures, video, text explanations, and he was always available for a call. It really put my mind at ease that the house was well taken care of in our absence. He ran the outside taps when it froze, kept the house at the temperature we requested, and cleaned up everything after. He also made us aware of little things like how the paint color we picked for baseboards didn't match the existing trim. With everything he did, made sure that we would be happy with the finished product. Quality: The workmanship is outstanding. The tile is cut and laid beautifully, with no hollow sounds when walking. My father used to lay tile back in his day, so trust me when I say it was well inspected after! Our walls have rounded corners, so it was very nice of Alter Construction to cut and round the baseboards instead of leaving them sharp. It looks very clean now. Attention to Detail: What really makes the work stand out is the team's attention to detail. They replaced a section of baseboards that wasn't in the work area to make them match because they were visible from the living room. They were kind enough to reinstall our baby gates at a higher position because the new baseboards were taller than the old ones. They even patched a hole in the carpet of one of our bedrooms with the scraps they pulled up from the living room. This wasn't something that we had asked them to do, they just took the initiative to really make everything nice for us when we came home. Summary: If you're looking for someone to do work on your house, you can't go wrong with Alter Construction. They'll take care of you like family and I promise you won't be disappointed."
