"Franklyn C. was very professional and friendly. It is clear he takes a lot of pride in his work. He made sure the print was perfectly centered top to bottom and left to right on the wall. He also cut part of the bottom of the radiator cover so it would fit over the molding and be flush with the wall. We look forward to working with him again."

"Matt and his crew were incredible. Everything was done on time and on budget, he even finished a major reno two weeks early! He is professional, his subs like working for him and he is very thorough and detailed. He was always available to answer questions, explains things in details, and is not pushy. He took the vision that I had in mind and made into a reality. I highly recommend Prestige Design and Build."

"Skies Are The Limit provided excellent service for us. We had a fireplace installed (required building out a wall), patio sliding door replaced, tv mounted, and ceiling repainted. Adrian got everything completed well. He managed the subcontractors to ensure things weren’t delayed, provided good suggestions on what we were requesting to make sure the finished results were great. He was also flexible in working with our schedules. I can’t recommend them highly enough .. beyond satisfied."

"I hired Cesar and his crew to gut and renovate multiple bedrooms a kitchen and 2 bathrooms. Cesar, Armondo and Benjamin were an absolute pleasure to work with. Their knowledge, expertise and craftmanship are top notch. Cesar is easy to work with and truly cares about making sure his customers are happy. Cesar has an uncanny knack for finding a solution to any problem he encounters. I found his pricing to be very fair and reasonable and I quickly learned I could trust Cesar. If you are looking to remodel, finish off a room or repair any part of your interior, Cesar and his team should be your first call."

Subcontractors FAQs, answered by experts

If your project is complex, it may make sense to hire an architect to draw plans. An architect might also be a good person to hire if you want to ensure your plans adhere to building codes and regulations.

Yes, professionals offer custom designs, including lattice tops and decorative post caps.

While concrete walls do not need to "breathe" in the traditional sense of the word, they do require waterproofing and dehumidifying methods, particularly in basements below the water table. Concrete both contains moisture from its initial installation and can absorb water when exposed. Ensuring proper basement ventilation , installing a vapor barrier, and controlling water exposure are all important tasks.

It usually takes around four to six months to build and install a modular home, although your timeline could go up to around eight months if there are delays in the manufacturing or permitting process. Heavy site preparation and foundation pouring can extend that timeline if you need them, as can customizations you want for your modular home. Your modular home company should be able to provide an estimate for the construction timeline before you sign any contracts or agree to any work.

Universal design costs can be minimal when you add them during construction; however, adding universal design principles to existing homes can sometimes increase renovation costs. For example, a mid-grade bathroom remodel is estimated to cost around $30,000, while a standard universal design remodel can cost closer to $40,000. Adding accessible design components can include widening hallways ($500 to $2,000), curbless showers ($2,000 to $8,000), and widening doors ($400 to $800). Keep in mind that these increased costs can lead to higher resale values because universal homes may appeal to a wider variety of buyers.
