"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

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.

Shipping container homes last at least 25 years on average, but they can last even longer with proper maintenance. Since shipping containers are made from metal, they’re quite vulnerable to rust and corrosion. This issue is exacerbated in coastal areas or areas with a lot of precipitation. To extend the life span of your container home, install siding that protects the exterior. 

Ultimately, a work warranty is only as reliable as the contractor you’ve hired. That’s why trust and reputation are such important factors, in addition to having a solid contract and confirming appropriate licensing, insurance, and bonding. When looking for a contractor, it’s a good idea to read online reviews and ratings to see what kind of experience past customers have had. Issues with your contractor can make for an unsatisfying renovation process, but a reliable contractor can make the process go as smoothly as possible.

An A-frame home can be cheaper to build than a traditional house, but that is not always a given. Prices can be fairly similar in some cases, depending on the location, design, and necessary site preparation. Costs for an A-frame typically run between $100 to $200 per square foot, which is comparable to the cost of a traditional home. The cost of an A-frame can come in under those numbers if you opt for a prefabricated kit.

Historically, Tudor homes originally stemmed from the 15th and 16th centuries, while Victorians appeared during Queen Victoria's reign in the 19th century. The design and structural differences are significant as well. The many types of Victorian architecture—such as Italianate architecture—typically feature ornate trim, wood siding, wraparound porches, and tall towers on top, such as belvederes. On the other hand, Tudor-style homes feature white stucco exteriors with exposed wooden rafters marking the house frame both inside and out.
