Customers say: Quality work

"We hired Ernest and Sons to construct our patio tiles. We purchased 2' X 2' Tiles and I have to say they did a gorgeous job. I was so pleased with the way they showed up when they said they would. The men that laid out on my job worked so hard. The labor was very strenuous but they never took a break. They were the most conscientious and polite workers I've ever dealt with. They worked neatly, cleaned up totally afterward, and just had a great deal of respect for our property. They really did a beautiful job and Ernest, the owner is a real gentleman also. Love this company!"

"Ray and his crew turned my dusty and damp unfinished basement into pleasant dry and clean useable space, and added a half bath. Work included pouring new concrete, new windows, plumbing, painting walls and new floor, electrical work, plumbing, new stairway, changes and new door in front entrance, outdoor lighting. All done with the pandemic to deal with. Very pleased!"

"Words can not explain how happy I am with the work done by All Around Renovations!! We worked with Michael using a construction loan and what I thought was going to be crazy stressful to manage was not in the least. Between the bank and Michael, everything stayed on track and within budget. Michael took my vision of what I wanted it to be and made it tens times better. Along the way, he also made suggestions as to how to improve certain things, and I couldn’t have been more grateful for that. I am so happy with the outcome of my “new” but “old” house - it looks so amazing. Most of all, I can’t wait to cook in my AWESOME new kitchen. Even though most nights I despise cooking, my kitchen is so pretty that I might actually start to enjoy it. I highly recommend All Around Renovations! Everybody was nothing but professional from day one, and it made the stressful process of home construction for me that much easier."

"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."

"John did outstanding job finishing basement in our house. He provided contract at the beginning of the project with the job descriptions and prizing. The prizing was reasonable. He strictly honors the contract. He worked personally with Livingston city authorities for job permit. John spent a lot of time with the city inspectors and completed all their recommendations. Work was done in very professional manner without any deficiencies. We are very happy! Definitely, recommend this company services to our relatives and friends"

"My wife and I DO NOT use anyone who is not on Angie's List so we understand the importance of having accurate, fair reviews. We found Cary on Angie's List with overall great feedback on jobs he had done so we called him in for an estimate. Despite being very busy, he made the time to come over on a Saturday morning. He had previously dropped by and assessed the damage from the outside but needed to see it from the inside to ensure he could judge it accurately. After 15 minutes, our fears were realized and he said he would need to remove the cedar impression siding and remove the roof and replace it with a different system because the pitch wasn't steep enough. 
Within 48 hours, he provided a quote for his crew to come out and get the work done in a single day which was completely reasonable. He completed the work (guaranteed) as promised and left the site immaculate. He took pictures of the issue, of job progress and of the completed job. He mentioned he went around and filled some other issues he noticed while he was waiting for his crew to wrap up, no charge at all. He then discounted the quoted, agreed price 5% for angie's list deal I wasn't even aware of. Have you ever heard of a contractor accept less than an agreed price? Me neither.
Angie's List is a great resource for people to share experiences. I think the contractors who are honest and reasonable should be applauded too. We have been on the receiving end of some really lousy service so this was a new experience having someone do what they promised to do. Cary and his crew are the best in Monmouth County. We already have him pricing out finishing a storage space and will use him to build our deck in the spring. I cannot recommend Cary enough and you can reach me through Cary if you'd like to see his work firsthand.

"Everything went well from start to finish. Mike is a professional and very knowledgeable. The price was not that much more than vinyl even though we were getting top quality Hardie siding and beautiful window/door trim and new gutters.  The house looks beautiful and I would highly recommend Mike."

Home Building FAQs, answered by experts

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.

There are energy-efficient options when building a cottage. Select green building materials, high-performance insulation, and energy-efficient windows when designing your cottage. Options such as solar panels, efficient HVAC systems, and LED lighting can lower your utility bills and reduce your environmental impact. Many builders offer energy-efficient upgrades as part of the design process.

It pays to hire a project manager or general contractor when you have a large-scale project that will take over a week to complete, especially when it involves structural changes and multiple subcontractors. This includes hiring a general contractor to build a house, add an extension, or manage other projects that need a building permit.

Whether a prefab home is worth it or not will depend on your personal needs and preferences. Overall, prefab homes tend to cost less than traditional homes, although they also tend to have lower resale values. Another thing to consider is that prefab homes usually last 50 to 60 years or longer, while traditional homes last 50 to 100 years or more.

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.
