We’ve hired Alta Construction for three different projects in our home, and every experience has been outstanding. Angel is an absolute pleasure to work with — professional, reliable, communicative, and genuinely committed to high-quality work. We first hired him to install drywall in our basement, and the craftsmanship exceeded our expectations. After seeing the attention to detail and quality of the finished work, we brought him back to build a custom tile shower, which turned out beautifully. Most recently, Alta Construction completely remodeled our kitchen, and we couldn’t be happier with the results. Angel consistently delivers excellent workmanship and takes pride in what he does. It’s hard to find a contractor you can truly trust, and we feel very fortunate to have found Alta Construction. I would highly recommend them to anyone looking for quality work and a smooth, professional experience.

Angel is very detail oriented and wants to make sure the customer is happy with his work. He takes extra time to make sure job is done with perfection. We love our new bathroom. We had bathroom remodel not kitchen.

Hired Alta Construction to install additional driveway with fence and gate work from start to finish, they did an excellent job. Angel’s communication and understanding of what we wanted done in the job worked well together. I would highly recommend Alta Construction for any home improvement project. Carol

I hired Angel to do a few different projects around my house: insulate and floor my attic, retile my bathroom, repair a sink with incorrect pipework and slow drainage, and some other odds and ends. With each task he was incredibly communicative about what was happening and how it could be solved. As he worked, he was clean, thorough, and the end result was beautiful. I am always hesitant to have people in my home I dont know, but Angel was incredibly kind and friendly and his open communication style eased my worries quickly. Plus my pets seemed to like him a lot too. I would highly recommend Angel and Alta to anyone who needed help with construction or remodel work. His pricing was fair and his work incredible.

Brought in Angel after starting our upstairs renovation ourselves, and it was hands down the best decision we made. He and his crew took over handling drywall, bathroom tile, fixtures, and carpet installation. The results exceeded our expectations. The space looks better than we’d envisioned and would absolutely hire him again.

Angel has done several jobs for us - drywall removal and repair, custom hatch door for an air handler, painting, and the installation of bike racks. He consistently communicates well, does quality work, and cleans up after the job. Would highly recommend him.

Angel did a great job building a walk in closet and installing a new door in our basement. Good communication, attention to detail and desire to get the job done right!

Angel did an excellent job installing new side kitchen door and sliding interior door with additional interior walls for more privacy and noise reduction for nearby bedrooms near kitchen and living room. He was very communicative and quick on scheduling. Completed work within expected time frame. Most of all, he provided passionate and beautiful work throughout the process. He will always be the first I reach out to for any future projects. Jimi

Angel did an amazing job with replacing a section of my fence! He was efficient, professional and reasonably priced! He took the time to make sure everything was to my satisfaction. Every time I look at my fence, I am so pleased with the work Angel did! I will definitely continue to call him when I have additional projects to complete!

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
