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!"

"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.

"We first invited B&A Construction team to provide an estimate for our new house renovations. Afterward, we showed the home inspection report for the house that we’re trying to sell and Luis was kind enough to stop by on the same day to our house to assess the issues and thoroughly explain what needs to be done. Given his expertise, it was very helpful for us to work with him as the inspection required various types of work, ranging from plumbing, HVAC to electrical. His work was very thorough and timely. Also, he’s very responsive when we text him and pleasant to work with. His price was also reasonable and better than few quotes we’ve gotten from other individual licensed contractors as he offered package deal for various work he has done. We are currently working with him on the new house renovation and he and his team have been very efficient. I can’t wait to see the end results. I highly recommend Luis and his company!"

"I found Nilsen Building and Remodeling from Angie's List and at the time, they had a 'Painter for a Day' promotion going on that I couldn't refuse - I thought, it's so affordable what could possibly go wrong? I reached out to David to coordinate right away so to take advantage of my voucher, and he was in touch shortly after and we were able to lock in a start date two weeks later. I was concerned about scheduling without having him stop by and seeing the space first, but he assured me there wouldn't be any concerns and that the job could be done within the 8 hours. To sum up my experience in one sentence - I am so happy with my finished, painted room and I will certainly be using David and his team for more projects around my house and would highly recommend him to anyone looking in the North Jersey area. The job included painting a lot of trim work and 2 accent walls. Once you get past the bright purple color I chose, you can see their high-quality work and attention-to-detail all throughout. Thank you!"

Home Building FAQs, answered by experts

Craftsman-style homes are predominantly found in the Western United States, specifically in Southern California, where the style originated. Since the climate was mild and there was access to plenty of natural resources, Southern California became a hub for this style at its inception. That being said, if you consult with an architect near you, you can have a Craftsman-style home anywhere.

Modular homes can be a great investment, especially for those who find the prices of stick-built real estate too high. Modular homes are usually much more affordable because they’re mass-manufactured and then assembled on-site or delivered mostly assembled. If they’re installed properly and by professionals, they can last for between 50 and 100 years, potentially making them an outstanding investment.

Yes, you can finance cottage construction through several options. Construction loans provide funds in stages as work progresses, while home equity loans or lines of credit are available if you have existing property. Some lenders offer a combined construction and permanent mortgage. Always review loan terms and payment milestones before committing.

No, a structural engineer is not the same as a builder. A structural engineer is an expert in all things related to the structural integrity of a building. The structural engineer is responsible for calculating the correct materials in terms of load-bearing capacity and overall structural safety. Structural engineers do not perform the actual building of the house or other structures. Rather, the builder executes the plans and designs specified by the structural engineer.

One of the best ways to negotiate with a homebuilder is to forgo price reductions. Instead, negotiate over upgrades and incentives, as many builders are more willing to go down that road than to decrease their own fee. Even if they were willing to take a cut, a reputable homebuilder often knows their worth, so a willingness to negotiate could be a red flag. Beyond that, builders are typically willing to negotiate closing costs instead of offering a discount on the base price.
