"David and his men are the real deal. The project went very smooth and the final product was better than I imagined. Not only are they skilled but they offered a clear line of communication and professionalism throughout the project. My wife and I were so happy with the addition that we already are planning them to come back for future projects. I highly recommend David and his team for home additions, custom work, decks, ect. Thank you David!"

"We were so pleased with the results. We had a complete home renovation. Al was so kind and not only listened, but homored our requests. He worked with us on the details of our plans. It was not your typical home reno as Al had to correct all of the work of a prior contractor. Al was reassuring and not only delivered on his promises, but produced such quality workmanship. The same goes for those he contracts with especially the painters. We have been living in our home now for two years and it's exactly as he promised: it feels like home, a place we always want to come back to. Thanks Al."

"Caseri Construction put a picture window in my first home. Several years later we hired Dan Caseri to build our new home. When it came apparent we needed our deck replaced we of course, called Caseri Construction. Caseri Construction shows up when they say they will, has fair honest prices , and they do top quality work. I highly recommend Caseri Construction for whatever size job you are looking to have done."

"We recently had a complete roof replacement. Before proceeding, we did comprehensive research of area companies and Vista came out on top, with good reason! All appointments were not only on time but were extremely punctual. We met first with Product Specialist Holly, who was enthusiastic, very knowledgeable and helpful. While at our home assessing the proposed job, Project manager Rick explained the entire process in layman's terms. The day of the job, Project Supervisor Marc arrived early and went over the entire job with the crew. All company representatives left us with a business card with their cell #'s to call if we required anything. The installation crew was amazing. They arrived early and began immediately. They were no nonsense, very focused and, worked like a well oiled machine. All Vista team members were polite and respectful of my special request to be cognizant around some of my more cherished trees & shrubs. Vista was fastidious in their care for my home and lawn, not one speck of debris was left behind. Vista, the installation crew, company representatives, everyone, exceeded our expectations. Vista stands behind their work and products. If you wish to relax after a major home improvement project knowing the job was done correctly, you will want to consider Vista. Dan & Kim Belchertown"

The owner, Dean is professional, very detailed and has a welcoming personality that immediately puts you as ease. Very knowledgeable and offers options to fit your budget. We had additional cabinets installed in our kitchen, (for extra storage) they arrived promptly and worked quickly, took a few hours and left the kitchen spotless. Great problem solving skills, we had a refrigerator that was too big for the existing space and they moved and customized a few cabinets to allow for a proper fit, all without missing a beat on the original project.   

We are pleased with the results and plan on calling them for additional projects that are on the list in the very near future

"From the first contact until the final payment everything about my experience with NE Renovations was EXEMPLARY.  I have lived in different states and different countries where I have had reason to employ contractors over the years, and I can say, without a doubt, that NE Renovations are SUPERIOR in every department.  Bill, Kenny, Mark and Anthony were COURTEOUS, EFFICIENT, SKILLED CRAFTSMEN; unobtrusive while simultaneously involving me, in as much as I wanted to be involved, each step of the way; no task was too trivial or too difficult, even jobs that were challenging i.e. finding extremely hard to find no longer manufactured parts was approached and attended to with SUCCESS, ENTHUSIASM and a POSITIVE attitude.  Every job was undertaken with a SMILE and PROFESSIONALISM.  Richard consistently communicated via email and telephone throughout in a PLEASANT and PROMPT manner. Mark and Anthony removed old appliances and some hard to get rid of junk in my garage at NO EXTRA COST.  Kenny worked METHODICALLY, PROFESSIONALLY and so  QUIETLY I would forget he was there, and Bill, what a gem ! - A MASTER CRAFTSMAN who can turn his hand to any job, who begins and ends his day with a smile and a kind word.THE FINAL COST WAS AS ESTIMATED DESPITE THAT I ADDD QUITE A FEW JOBS ALONG THE WAY - AT NO EXTRA COST! The work was done in a timely manner and for the first time in my experience with contractors it was an absolute pleasure to greet this team of craftsmen each morning at 8am. I am an extremely happy customer and would highly recommend NE Renovations. The result of their efforts is apparent in my now BEAUTIFULLY and PROFESSIONALLY renovated home."

"Bill and his team were nothing short of outstanding. Excellent communicator and overall nicest, honest  professional you can meet. From Day 1, Bill was 100% customer service-oriented and ethical. However, the completed  work was also of quality workmanship. He managed the project with multiple partners and always made it seem like he was doing it all himself. We were very challenged finding a suitable contractor for this home as this project was very challenging, but Bill made it easy. Outstanding!!

"IT was great! I have never had a problem working with this company. The people (from the customer service reps to the billing to the drivers) have all been honest and realistic with expectations, answered all of my questions and never charged me more than what is advertised on their website. Patricia and Victoria have gone out of their way to return my many phone calls on the weekends too. You just don't get customer service these days anymore like the bullbag provides.They came when they said they would, did what they said they would do and did it professionally and pleasantlly. It is a pleasure working with such an honest and reputable company. Especially since the dumpster industry has not been know for this! These guys are definitely setting the bar high for all their competition."

Custom Home Builders FAQs, answered by experts

Remodeling a house is often less expensive than building a new house. You can expect to pay an average of $100 per square foot when you are remodeling. The cost to build a house averages about $150 per square foot. When remodeling, though, some rooms cost more than $100 per square foot and some cost less. Use a home renovation cost estimator to accurately estimate your remodeling costs.

Above all, the downside to building a new house is a longer timeline. You need several months to finish the build, depending on the supply chain and labor availability in the meantime. Building a home compared to buying one is also more expensive, both in the building process and when it comes to mortgage rates and property taxes.

How long it takes to build a log cabin depends on a variety of factors, including its size and design, and whether or not you have to clear the land. Construction can take a few weeks for a prefab log cabin on an established site, but up to eight or nine months for a custom cabin on undeveloped land. In comparison, the timeline to build a house is typically four to 12 months.

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.

Buying a house is easier than building one from scratch. Buying an existing home is almost always faster, even if you need to make renovations once you move in. When you hire the right team to build a home, they will simplify the design and build phases so that there is little guesswork throughout the process, but building new construction will almost always take longer than buying an existing home.
