At American Construction, Plumbing and Electric, we’re a full-service remodeling and construction company proudly licensed in General Contracting, Plumbing, Electrical, and HVAC. With all trades handled in-house, we provide streamlined project execution from start to finish—eliminating the delays and miscommunication that come with outsourcing. Backed by over 30 years of combined experience between our business partners, we deliver professional, code-compliant work across all phases of residential and light commercial construction. From kitchen remodels to full home renovations, we’re your one-stop solution for quality craftsmanship and reliable service.

"We originally wanted to wait until our spa was fully finished to leave a review, but we just had to rave about Gabe and his team. They have been SO easy to work with—and when you’re opening a second spa location in San Diego, easy is everything. Gabe moved fast (he’ll be done by Monday—EEK!), and for business owners, time is money, so having a contractor who’s in and out efficiently is HUGE. During the project, he discovered some mold in the building. Not only did he notify the property owners immediately, but he also took care of the remediation, followed all proper protocols, and handled it all on his own. We’re forever grateful for how quickly and professionally he resolved it. Honestly, our favorite thing about working with Gabe is how he consistently goes above and beyond—especially in ways we didn’t expect, which meant a lot to us as two female business owners. We never once felt taken advantage of, which sadly can be a rare experience in this industry. To give you an idea of how fast he worked: our space includes five treatment rooms, two storage rooms, a kitchen, an office, and a lobby. He redesigned and completed the whole buildout in just over a month. He’s also a great communicator—sending us frequent updates, photos, and videos of the progress, which gave us so much peace of mind since we couldn’t always be on-site. His pricing is incredibly fair and, in our opinion, makes him unmatched in this industry. His work is impeccable, and it doesn’t break the bank. We truly could not recommend Gabe and his team more!"

PLEASE NOTE: All our services and consultations are conducted exclusively in English. Brian Thomas Consulting Inc. is a family owned and operated local builder that has been around 30+ years specializing in kitchen remodels, room additions, ground builds, and multi-room remodels. We focus on large-scale projects with a typical starting budget of $80,000.

"I hired Brian Thomas from February 2020 through March of 2020 and here are the reasons why I do not recommend using this company: 1. The contract I signed with them was for one year, 12 months, of SWPPP inspections, for which they quoted me $13,390. After less than 2 months worth of work, when I had to end the contract, they had already billed me $14,422.61. 2. Part of those charges included a $1,119.34 charge for “material markup”. They had stated that the materials they were going to provide, for erosion control, were going to be supplied at cost. When asked about this “markup” charge they stated “we charge a 15% mark up on materials”, because “ordering your materials puts a potential burden on the company”. So that is what this company means when they say “at cost”. 3. When Brian Thomas first came to my site to start the work he stated that he was there on his own dime “to help”. On his final bill he included two charges totaling $595 for such visits. When asked about these charges their response was: “[Brian] did not state that he was consulting free of charge” and “if you hadn’t removed us from the project after just a month of being on it, Brian may have been willing to remove those charges”. So that is what this company mean when they say “we are here to help on our own dime”. 4. When asked about the $5,000 worth of inspections they performed in just over a month their response was to send some documents so that I could “educate yourself on what is required per your SWPPP”. The company I was using to perform such inspections, and who I re-hired after I terminated Brian Thomas’ contract, charges me $1,000 to perform the same inspections. In other words Brian Thomas charged me 5 times more than an average company does. Brian Thomas will use their “knowledge” of the requirements for these inspections to charge you as much as they possibly can even though the State does not require that many inspections. 5. My relationship with Brian Thomas started to fall apart when they started to push additional services on me. I’ve had a grading company doing most of the work for my grading project for over a year (and I am about 2/3 done with the project). First Brian Thomas suggested they had a crew of people that could install BMPs, something my grading company was already doing, and then they even suggested that I should fire the grading company I was using (because they were incompetent). Having the same company that performs inspections also perform the work needed to pass those inspections is a conflict of interest: you are essentially creating work for yourself. But that is how Brian Thomas works. 6. When managing a grading project there are 2 main inspections you need to perform: a SWPPP inspection and a grading inspection. Brian Thomas can only perform one of them: the SWPPP inspection. If you are planning on doing a grading project I recommend getting a company that can perform both inspections, like the one I am using, and not a company that can only perform one of them, like Brian Thomas. This was my experience with Brian Thomas. If you chose to use them for your project may you have a better experience."

Founded in San Diego, "I'll Handle It" is a home grown business that prides itself in its responsiveness to its customers needs.

"Dave was great! The best communication and transparency I've seen in a long time. Dave explained what he needed to do to install the dryer vent and got right to work...NO wasted time. He installed the vent and made sure it was working properly. The vent looks great! Dave is knowledgable, professional, and a nice person. He also stayed in touch, letting me know how soon he would arrive and when he was on his way. I really appreciated that. We will definitely call him the next time we need a handyman."

FAQs for addition to existing structure building service projects in Alpine, CA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
