"I found GenJazz through Angi, and Fernando came by and measured, took pics, and listened to what my wife and I wanted. He was friendly and personable. Super nice guy. Really appreciated that he understood what we were trying to do with this space. His quote wasn't the cheapest, but it did seem the most responsive to our vision. We made some changes on the fly. After initial demo, we decided we wanted to upgrade the stone around the bath as well. We made changes to the glass surround choice, even sourced a reasonably priced custom cultured marble shower pan, which Fernando and his guys thought would look great. They were SUPER responsive, and tried to help us save money where it made sense. Also, ALL of the guys that did the work were kind, thoughtful, and polite. Alfonso, Joe, and workers were great with my wife, 4 kids, and puppy, who were always around since we homeschool. They cared about the quality of the work. Super happy with the bathroom, and would pick them again!"

"Best in the business! This was the 2nd house I've remodeled and Dave & his team outperformed all previous positive experiences & expectations. They removed 3 pony-walls, installed new porcelain, large tile flooring throughout (2200 sq ft), remodeled the bath to enlarge the shower,-added a modern stand-alone tub, installed new double marble-topped vanity, marble mosaic wainscotting throughout the bath, a marble-porcelain 7-foot long/12-foot high shower with luxury finishes (marble bench & rainshowers) & a chandelier above the tub with sconces flanking a 6-ft long mirror. They renovated the kitchen with new cabinets, pendant lights, quartz countertops on a new, better positioned island that Dave designed, porcelain flooring, under-cabinet lighting, and gas-burning double-sided fireplace before installing gas-top stove, electric wall ovens, refrigerator, dishwasher and double-work sink. They even installed 3 chandeliers (living room, dining & media rooms), drapery hardware at eight floor-length (12-ft high) windows & sliders, and an amazing new wet bar with vessel sink and marble with brass inlay backsplash!! They're prompt, hard-working (many times working on Saturdays and Sundays to meet deadlines), kept the project moving - even with supply delays (store's fault - not theirs) and additions I requested. They're attentive to detail, sensitive to HOA demands (never arriving too early & removing outdoor trash immediately), and professional at every turn - keeping the workspace clean/tidy. Dave goes above and beyond to satisfy his customers, reviving the art of customer service and taking it to a whole new level. For example, and though it wasn't on my list of repairs, he noted that my "new" home's air ducts needed cleaning - and shopped around for quotes I could afford. Likewise, he flushed my failing water heater in attempts to save it (original to house built in 1997). I can't say enough about this fabulous team of professionals who are as kind and personable as they are professional and skilled. I strongly recommend Dave and his team for ANY home remodel you're considering. Dave's part-designer in addition to being a fabulous contractor. He made several suggestions along the way, and I'm glad I took his advice (otherwise I wouldn't have this amazing, gourmet kitchen w/double-fireplace!). I interviewed and researched several contractors before engaging him with most exceeding his quotes by 15-25%. He's reasonably priced, comes when he says he'll be there, and makes sure the client is happy with the final product. (He even checks back a couple of weeks after the job is completed to ensure everything is functioning as it's supposed to.) I'm hiring him for my next project of replacing entry doors, and am absolutely confident he'll do a phenomenal job! THANKS DAVE, LOU and WAYNE!!! You're the BEST!! (And SnowBall sends puppy hugs to each of you!) :)"

General building contractor who currently works independently and is looking to grow business to hire one employee. I do mostly carpentry and cabinet making my self. I do perform other trades depending on how much there is. I have good dependable subcontractors that I call when necessary. Depending on the size of the job, I ask for down payment and progress payments or may just wait to bill the job once it is complete.

FAQs for addition to existing structure building service projects in Modesto, 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.
