"We have been working on our kitchen remodeling project with Shay at Cal Green Remodeling this past month. They are a great company, who knows what they are doing. Shay was knowledgeable and had a lot of experience which is shown on the results and while at the process. The workers were very clean and respectful of our privacy and our home. The kitchen looks great, was done fast and we are very happy!"

"Our kitchen remodel with McCormick Home Builders went beyond our expectations. Leoni and her team took the time to understand exactly what we wanted. The open layout design changed the way we use the space, and it’s been perfect for family gatherings. They were prompt, courteous, and genuinely invested in making sure we were happy. Really impressed!"

"We learned of Wise Builders from our neighbor down the street who had their kitchen and bathrooms done through Wise Builders. They spoke highly of the company and the results of their remodeling took the word impressive to new heights. We contacted Wise Builders as we needed to have our kitchen redone after a water leak caused some major havoc. We spoke and met with Nathan Weizmann who came out to our house and did a thorough review of our requirements. After a question and answer exchange, we agreed that this was the company we wanted to do our kitchen redo. We have worked with contractors in the past and Wise Builders ranks up with the best of the best. Their attention to customer service and project detail is excellent and if I say anymore, people will think I'm a paid employee disguised as a customer. Bottom line, we recommend them without question, hesitation, or doubt. As a matter of fact, we did"

"I had to have my entire bathroom torn out and replaced with new walls, new enclosure, tub and flooring. I am very happy with the job that Cobar Builders did in my home. They were all very friendly and updated me on their progress and asked me how I liked certain things done...honestly this is the first time I have ever hired a contractor to do work in my home and at first I was very nervous, but all my fears and worries have been allayed by Elvin, the owner, and his crew. Elvin and his team were always up front with me about any additional costs and was very responsive to my calls and texts. I definitely recommend them highly."

"We found Landmark construction energy crew, after being frustrated in the past from other contractors. From the initial meeting that we had with Charlie, we were impressed. Their values of customer satisfaction and their deliver everything they said. Charlie was the manager of the work and he was on time for all the meetings that we had with him. He was very straight, kindly and motivated to be invited into our house. He came back and took all the measurements that he needed for the kitchen, asked us many questions about what we would like to include in the new kitchen and 3 days after, he brought us a 3D design for us to look at and see how it will most likely look like. It was exciting to see how fast they could generate a nice design. Charlie knew what he’s doing and we were sure he has done this type of jobs many times before. Their prices are reasonable. We wanted our kitchen finished as soon as possible, so we agreed with Charlie to start the following week. That gave us little time to buy all the appliances, hardware, countertops, tiles Etc… Charlie personally went with us to 2 showrooms where we picked out our tiles and countertops. He also helped us to search and buy all the options for the (sink, faucet, hardware and more…). To be honest, I was probably a nightmare type of work. We moved out of our place during the month of the remodeling and we were a little worried that something would go wrong and we would end up on a terrifying remodeling show. Now after this remodeling is over, we can say clearly that is nothing to worry about when Landmark construction energy crew are working at your house. Their workers was clean, friendly, willing to answer questions. I discovered that Charlie visits the job site every few days, but he too sincerely cares about your home. He always called regarding the schedule, timeline or if there was a problem that need to be solved. We asked for changes to the electric wiring after the tiles have been installed. Would I recommend them to others? Absolutely yes. We will refer this company to all our friends."

"We worked with the A2Z team on a renovation of our downstairs to convert a den space into a new bedroom/office with a full bathroom, our living room to make it a more open floor plan, and updated the electrical in the whole house. We began the project in January of this year and were able to move back in June with the project fully completed in July. The project manager we worked with was Meir and we would plan to meet weekly to review and discuss the progress of the project. The project did complete a little later than expected as there were a few setbacks and challenges that came up but Meir was always there to work with us to make sure we were happy with the work/solution for these setbacks and challenges. Meir always made himself available for a chat either by text, phone, or email. If there was something that needed my attention or an update following an inspection, Meir would notify me right away so I was kept informed of everything. After everything was completed, my wife and I were happy with the work at our home. When I am walking around my home, it feels like a brand new home and I forgot how it used to look. There were some bumps in the road during this project but now we enjoy being back in our home and had a super positive experience with Meir and A2Z. If you are looking to renovate/remodel your home/property, I would recommend reaching out to A2Z."

Custom Home Builders FAQs, answered by experts

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.

Yes, such as using eco-friendly materials and energy-efficient designs for long-term savings.

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.

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

A carriage house is a freestanding building, while a townhouse is connected to other units. A townhouse is a full single-family home and typically shares a parcel of land with other connected homes. A carriage house is rarely used as the sole single-family home on a property and is most often an additional building sharing property with a traditional single-family home.
