"Anush and his team were absolutely amazing, and our porch turned out better than we expected thanks to his ideas/recommendations. The attention to detail/pride they take in their work truly stand out and far exceeded our experiences with contractors in the past. One of my favorite parts is how much I genuinely love coming home now. It completely changed the look and feel of the front of our house, and every time I pull into the driveway it makes me happy to see it. I will absolutely be recommending AVSTEP to anyone planning renovations or building a home. We already have several more projects planned for our house in the coming months, and without question we’ll be using Anush and his team again. It’s such a great feeling to know we now have a contractor we genuinely trust and can confidently call whenever we need work done. Even our neighbors have been commenting on how beautiful the front of our house looks and what an incredible job they did. Below are the before and after pictures"

Customers say: Quality work

"They are not local to my area. Please, hire local. And this is for Angi: Try not to recommend contractors who are a significant distance away, in this case around 80 miles (and 2 states) away. Great website, appears to be professionally designed and maintained, I like what they do (judging from the content in the website) but I am outside their service area. I don't live in that area. If I owned a home or apartment in that area, I would hire them."

"If you're looking for a budget job, keep looking. Jack isn't cheap, but he gives you the highest quality service and work. Started on time, worked continuously, finished on time. Spent a lot of time with us discussing the options and planning the work. "Old School" perfectionism. Minimized household disruptions and cleaned up well at the end of each day. Came immediately when we had a minor problem after the job was completed and paid for. The finished product looks fabulous. And if you're a dog lover, you might even get to meet Jack's french bulldog Coco."

"Our entire job was extensive, replacing all windows (new construction not inserts), remove/install siding, replace all outdoor trim changing it from wood to Azek, new indoor trim around new windows, new soffits, new gutters, new front door and surround, new garage doors, new outdoor lighting and new front porch.  The first contractor not only walked off the job but his work had to be removed and redone due to poor workmanship by the first contractor.  Cary came to the rescue, because we continued to uncover more work that had to be redone we paid Cary and his helper by the hour.  His work ethic was unquestionable.  He showed up on time and worked the promised 8 hours.  Cary did all the siding, soffit installation and basic outside trim which included a 1 x 8 freeze board a 1x4 board, dentil molding then cove molding along the roof line. He also cut the arches from the Azek.  Because my design for the front door surround was rather intricate Cary brought in two carpenters who were unbelievably talented.  He had them cut the remaining dentil that was needed on site.  He also brought in someone who installed the gutters and downspouts. Cary also installed our french doors with a retractable screen and as the Anderson construction rep said, " this is the best installation I have ever seen".  The overall project went smoothly once Cary took over the job.  He is respectful and listens to what you want and most importantly was there when I needed him."

"Luis is very nice person to deal with. He came in to do some quick electrical work for me. He was reasonable compared other electricians and did a good job resolving the problem quickly. He helped me replace a few breaker to new ones with arc fault breakers."

Home Building FAQs, answered by experts

The longest part of building a custom home is the design phase. It takes multiple professionals and a ton of work to bring your vision for your dream home to life while sticking to a homebuilding budget and also ensuring everything is built to code. Expect the design phase for a custom home build to take six months to a year.

In most cases, you should get an architect before you hire a builder. An architect will be the one to draw up formal plans for your project, including guidelines and even material lists for your builder to follow during construction. Many architects can even help you find builders, choose one for your project, and negotiate prices. Some are also willing to act as project managers throughout the process, working closely with a builder from start to finish.

Modular homes last an average of between 50 and 75 years, and high-quality modular homes can last for 100 years with proper maintenance. For comparison, a standard home lasts 50 to 100 years and can push to 150 or longer with good maintenance. Modular homes provide better long-term value in that they are significantly more affordable and can last almost as long, but some buyers are wary of modular home longevity, so the actual value if you sell could be lower.

In most states, you can build an in-law suite on your property as long as you follow local building codes. However, it's important that you have enough space on your property to accommodate the new structure. A functional in-law suite in your backyard will require between 300 and 800 square feet of space.

The average cost to renovate or remodel a home is $52,300, with most projects ranging from $19,500 to over $88,400. However, costs can vary significantly, from as low as $3,000 for a small project to $170,000 or more for a complete home remodel.

Several factors influence the total price, including:

  • Project Scope and Size: The extent of the renovations, whether it's a single room or the entire house.

  • Location: Geographic location affects labor and material costs.

  • Materials: The quality of materials chosen.

  • Room Type: Kitchen remodels ($14,500 - $70,000+) are generally more expensive than bedroom remodels ($1,500 - $5,500).

  • Other Factors: The time of year, complexity of the work, and any additions or expansions.

On a per-square-foot basis, you can expect to pay between $15 and $60 for standard projects and up to $150 for luxury renovations.

Examples of specific project costs include:

  • Basement remodel: ~$20,200

  • Garage remodel: ~$27,900

  • Loft conversion: ~$20,200

  • Disability accommodation remodel: ~$4,300

  • Major home repairs: ~$11,700

If you are financing the project, note that some loan programs, like the FHA 203(k), may require a minimum project cost (e.g., $5,000) and will necessitate a home appraisal and professional cost estimates. Using a home renovation cost estimator can also help you budget for your project.
