"Wonderful! Look no more: You have found a triple licensed (general, electrical and plumbing) builder who keeps on budget, has great aesthetic taste, is creative and keeps to his schedule AND he sends in a professional cleaning crew at the end of the job! What contractor does THAT? We have already hired him for two more jobs, one at our 2nd home in Sedona and for a remodel of a condo our son just bought. In between our neighbors hired Vicente for a bathroom remodel at our recommendation. They have already told me they are thrilled with hiswork. Book LEAN Construction as soon as you finish reading this...this 3 year old firm will be booked up very soon. You have found your contractor!"

"Absolutely love how my bathroom remodel turned out! The team at Shepherd Contracting was super professional and made the whole process so easy. They worked fast but didn’t cut any corners, and everything looks amazing. Communication was great the whole way through, and they actually stuck to the timeline (which never happens with renovations lol). Plus, they kept everything really clean, which I totally appriciated. If you’re thinking about remodeling, I 100% recommend them!"

"I sought 4 bids for this work and when I met Dana I immediately knew I wanted him to do the work.  He was prompt, professional, and really knew his stuff.  He explained everything to me without being condescending and was able to laugh with me about the challenges of remodeling.  He estimated that the work could begin at the end of this week but ended up calling on Monday and offered to start work on Tuesday.
As promised, his Assistant Walter, arrived and began to work.  Walter quickly but thoroughly prepared the home for painting.  He worked tirelessly for 2 days to finish painting and then completed all the crown work on the 3rd day.  He was efficient and great at his job.  He also cleaned up each day and left my home completely intact at the end of work.
Toward the end of the job I asked Dana if he could add some other work on (putting moulding on some cabinets) and he readily agreed to start on it ASAP.
The results are amazing and I couldn't be more pleased.  This was worth every penny and I would recommend iCrown to anyone!

"We have all heard those stories of contractors you can't reach and who don't do what they say they are going to do. This isn't Robert of Freak Dog Construction. He is a true professional who keeps you informed and is on site every day to ensure that the workers know what needs to be done. If it is not done right, he will have it redone to your satisfaction. Last year Robert remodeled my kitchen and breakfast nook. They took out all the soffits and moved walls so we would have more room for the cabinets. Of course, all the wiring for the house comes in through the kitchen and had to be untangled and tucked into the ceiling. New LED lights were installed in the ceiling and under the cabinets. The cabinets were custom made and turned out beautiful! The tile work and new flooring was without blemish. I get rave reviews every time someone sees the kitchen for the first time. I was extremely happy about how the remodel went so when I decided that the three bathrooms needed updating, I knew I had to call Robert back. We went over the plan multiple times. He was attentive, asked questions and took notes and had his trade people come to listen and ask questions. He took out the soffits in all the bathrooms, making them look much more spacious. New LED lights were put in the ceiling and electrical moved to put sconces on either side of the mirrors. Plumbing issues were discovered, when the soffits were removed, and were fixed. The showers were torn out down to the studs. All the plumbing was updated and then the showers rebuilt and tiled. They turned out more beautiful than I imagined. Robert used a tile guy, Miguel, that is very talented at what he does. He takes pride in his work. Custom counters were installed with quartz tops and stone bowls on top. Everything done to perfection! All three bathrooms were torn apart and rebuilt in about six weeks. Drywall, electrical, texture, paint and tile were done. There was never a day that I didn't have workers here all day creating what far exceeded my expectations. Robert came by here every day and ensured that the work never slowed, and everything was done in the appropriate order. Robert communicated with me about who was coming and when. If I had a question or concern, he always listened to me and address the issue. He really is a great guy and makes you feel like your project is the most important one he is working on. The whole project came in at the contract price. I honestly believe that I got the better end of the deal! I still can't believe these showcase bathrooms are in my house!"

FAQs for basement remodeling projects in Surprise, AZ

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
