"He did an awesome job. The stairs came out just as I imagined. He made basement stairs to meet code. This was not part of the original project request. He was very friendly and professional. He was on time and cleaned up before leaving for the day. I am very satisfied with his work and would hire him again."

"Two small jobs, both completed in a quality fashion. One involved repairing an inside ceiling and one involved repairing a hole in my house's shingles and sub-roof. The more involved job came in significantly under the estimate, which shows the integrity of this company."

"When our deck and stairs needed to be resurfaced with new lumber, we got estimates from 3 contractors through Angi' s list. Azevedo offered the best estimate. We called Azevedo on Saturday offering them the job. They came out on Monday and finished the job in one day. Not a scrap of debris was left behind on the deck or yard. We could not be more pleased."

"Jim and crew are reliable and knowledgeable. I agree with all that Dana C in Kensington shared. We hired Jim to close in a carport for an addition by seeing the work he was completing for Dana. I then had him remodel an old garage that needed a face lift. We now have Jim building a ranch home for us from the ground up. It is going just as well. If only the prices due to the economy were not so disappointing. Materials are through the roof as a result. Here hoping for some REAL change in 2025 !!!!"

Meeting somebody, being invited into their house, and listening to their ideas of how they would like to transform their space to better suit their needs excites me. It brings me immense pleasure to be welcomed on an idea based visual journey in creating a customized dwelling in order to improve the quality of function in somebody's daily home life. Bringing ideas to fruition is my specialty. With equal enjoyment in making those popcorn ceilings that you've adored for so long disappear in an array of smoothness, gutting the kitchen where nothing seems to fit anywhere, including the cook, and installing cabinets and lights that transform the "heart of the home" into a space you don't want to step out of, or erecting that garage and mudroom to get your cars out of the weather and the clutter out of your foyer. At Magic Frog Carpentry & Woodworks I live in a solutions based mentality.

"Excellent work and priced very reasonably. Would hire them again."

Addition to existing structure building services FAQs

Building an in-law suite takes between two and seven months. Converting an existing basement, attic, or room can be done in about two months. Constructing a new addition or detached suite often takes four to five months for construction, plus one to two months for permits. The bigger the suite, the longer it will take. 

Yes, you can build an in-law suite in your backyard if you meet local building codes and zoning regulations. An in-law suite often occupies 300 to 800 square feet. Be sure to follow size restrictions, utility separations, and entrance requirements. Hiring a qualified contractor ensures you meet all regulatory requirements because they can pull permits, double-check local code, and gather other skilled pros to work on your suite.
