"We hired MHI Home Improvements to renovate our entire Kitchen in Bethpage, NY. We are so happy with the work ethics and final product. His staff would sweep every day before they ended for the day and make sure they left everything clean and tart early on time the next day. The entire job was finished timely and we get compliments all the time. My wife and I are more than happy to recommend MHI Home Improvements for any of your home improvments!"

"Gary and the team did a great job. My wife wanted a timber frame look to the front entrance and the guys created an amazing custom look. Gary made some design suggestions along the way, and we think they really enhanced the overall look. This is the 4th or 5th time we have used Kentstruction and I cannot say enough great things about them."

"Great! John has done many projects for us in the past but this was a major one. He was our general contractor for the entire project. We basically gutted our old kitchen, dining room and living room, raised the ceiling two and a half feet, and then built an addition that connected to the opened up space. He found us excellent subcontractors for every phase of the construction, e.g. the architect, framers, landscapers, electricians, plumbers, demolition, drywall, spackling, insulation, carpenters, roofing, gutters, flooring, tiling, countertops, painting, heat and air conditioning, motorized shades and home theater installation, you name it, he found us a top notch expert. Throughout the construction John was responsive to all of our questions and concerns and he took care to make sure that the job was always done right. His crew was always helpful and they would go out of their way to help and make sure everything was neat and tidy at the end of each day. But the most important thing Valeri Construction brings to the job is confidence that you will get the highest quality of work in the end. John oversaw the subcontractors who built us a brand new kitchen with new cabinets, countertops, backsplash, sinks, lighting and appliances. Another thing that we really appreciated was John's skill as a master carpenter. He and his crew installed a cedar ceiling throughout the entire indoor space, an entire wall of built in oak bookshelves with a rolling library ladder, along with a beautiful deck with ipe wood flooring. They also made extensive improvements on the exterior of the house, putting up cedar shingles, a bay window with a copper roof, and a spiral staircase that allows access to the deck. We are very happy with the end result and we highly recommend Valeri Construction for any home improvement project. John and his workers are a pleasure to work with and you will not be disappointed if you hire him for a project."

"Wonderfully. The Al-Arsh crew is always reliable, prompt, professional and highly-skilled. Their work is always done exceptionally well and the owner, Malik, always makes sure it is finished to perfection. Even when we needed something tweaked or if plans changed after they finished, they come and do whatever is needed when needed, cheerfully. Their prices are more than fair and they guarantee their work. We have had Al-Arsh do work for us over the years totaling at least $250K and we ALWAYS chose them."

"112 Home Improvement was recommended to me by my cousin.  They had remodeled his home and he was very happy.   We called John about a year before we wanted to begin.  We didn't even know exactly what we wanted.  He offered to come out and help us plan this project.  Once we figured out what we wanted to do John brought out his architect (Tom) and we started the process.  Plans, permits, surveys, variances the list is endless.  I am glad we did this well ahead of time.  Finally 9 months later (thanks town of brookhaven) we had everything needed to begin.  The work began in March and continued through June.  Everything went as good as can be expected.  There were some problems here and there but nothing that we were not prepared for.  In the end our home is beautiful.  We extended and remodeled our kitchen and created a great room, finished our basement, added a master bathroom, replaced our roof and our siding as well as added a deck.  My family and I could not be happier.  We absolutely love our home.  Thank you John and company!!"

Custom Home Builders FAQs, answered by experts

Check reviews, compare quotes, and verify licensing. Ensure the builder has experience with modular construction.

Handypeople usually don’t hold trade licenses, so they typically aren’t qualified to tackle projects involving installing or making alterations to plumbing or electrical lines. Below are some jobs that a handyperson usually won’t be able to complete:

  • Installing plumbing for a new kitchen or bathroom

  • Replacing plumbing pipes

  • Installing or repairing septic systems

  • Running new electrical wiring

  • Installing a subpanel

Hiring a reliable home builder is an essential task, but there are a few questions you can ask a potential builder to ensure you they are trustworthy and up to the task:

  • How long do you expect the process to take?

  • Are you fully licensed and insured?

  • How much of the work will you subcontract?

  • Will you pull all of the necessary permits for the job?

  • How long is the builder’s warranty you include with your work?

  • How do you handle resolution for issues I might have with the finished product?

  • How much experience do you have?

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.

Renovating or remodeling an existing structure is usually less expensive than the cost to build a new house. That’s because you can save on the costs of new building materials, laying a foundation, framing the entire building, and installing new materials and utilities throughout the house. However, if a home is in very poor condition or is incredibly old, you could spend more on upgrades and restoration compared to building from scratch.
