"I hired Robert after he did a remodel for my parents kitchen. The work completed was beyond expectations and at a reasonable price. The quality of work was excellent.

"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!) :)"

Addition to existing structure building services FAQs

How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.

Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
