Customers say: True professional

"We hired McCormick Home Builders to remodel our living room, and we are beyond pleased with the result. The team was professional, worked efficiently, and Aris design ideas made a huge difference. The room feels so much brighter and more spacious. This was the best decision we made for our home, and we were already planning our next remodel with them."

"Great experience with Armada Construction! Ivan and his crew were fast, reliable and trustworthy. We hired them for an extensive bathroom remodel and loved how careful and respectful they were with our home and pets. They never left our gate open and always took time to greet our dog:) They brought our bathroom vision to life. They moved toilet, shower and vanity locations and did a beautiful installation with our tile. Definitely recommend this crew!"

"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."

"Tony and his team helped us immensely. We met him originally during the design phase of our project and from that time on he was there to help from beginning to end. The project was approximately 700 square feet and included adding two new bathrooms, a master bedroom and a full remodel of our kitchen. Tony and his project manager Marcos were always here to give us updates and share ideas. They even helped us with finding the best places to go for supplies (tile, windows, counters, etc). Two of our biggest concerns was that we wanted to stay in the house while construction was going on and that the project finished on time. Tony was able to finish this large addition and remodel all while we stayed in the home and within a week of our original deadline. His team was always there working and were very professional. We will definitely use Tony and his team again in the future!"

"Cielo Construction has completed several projects in our house including the remodeling of our guest bathroom, master bathroom, kitchen and living room area. The design and remodeling was a custom European style/modern while the bathroom included a walk in tile shower, jet shower system, home automation and more… part of the design was to reposition the door opening for a much better use of space. Cielo construction staff helped us by selecting all of the finish materials including the tiles, upper and lower cabinets, accessories and more… including the color/style of the paint. Mike included also in his work the remodeling of the guest bathroom, drywall, type of texture, baseboards etc. He has excellent, professional craftsmanship and creativity skills. Cielo constructions approach and talent to meet our deadlines were fantastic and he was able to finish the remodeling project on time. We definitely recommend Cielo Construction and all the involved people that worked at our house for any type or style of construction or remodeling projects. We are very pleased with the completed project and we will hire them again for more upcoming projects. Thanks Cielo construction for a great job from a very happy customer."

"I had an excellent experience with Ocean Seven Builders that I wanted to share with the google community. I had a kitchen and 2 bathrooms remodeling project, and I had no idea where to start. I interviewed a few companies but Eli, from Ocean Seven Builders, was super informative, honest and straight-forward. Throughout the entire project, communication was great and they always kept us informed and updated on the progress. Whenever we were uncertain about a decision, they patiently walked us through the options and made sure we were happy with the results. Also, Eli and her team were extremely conscientious about issues that came up and dealt with every issue calmly and efficiently. To sum it all up, From booking an appointment through having the job completed, Ocean Seven Builders was fabulous to work with. They were responsive, courteous, and displayed a high skill level throughout the entire project. The finished result looks very high end and we managed to stay on budget. Thank you Eli and Ocean Seven Builders for my lovely new home."

"Team was fabulous to work with, hands down. My vision was to add more living space without adding square footage. Expert Home Builders made it happen. Walls were moved, doors rearranged, pocket door installed, custom shelving, new kitchen with extra seating, and new bathrooms came to life. I felt I was part of the Expert team. My vision and their high standards created my perfect place."

"I used Just Do It Builders to paint a small bedroom, repair a leak in my shower, repair an outside leak, replace a window screen, and clean a shower drain. All the technicians I dealt with were extremely professional and did a wonderful job.  The shower leak especially was difficult to repair and took longer than anticipated, but they put in the extra time to ensure it was repaired properly and brought in a plumber when he was unsure how to proceed.  I trusted him enough to give him a key to work while I was not at home.  The crew was also very clean.  They even sent a technician back in the evening to show me and explain the detail of what he had done.  I will definitely use Just Do It Builders again!

"Firstly. I can not  recommend Gabriella highly enough for her knowledge at new construction and remodeling,
and understanding our needs for our projects.
We were  so satisfied with her work, that we used Flawless Design Group Inc. for two of our houses in
Tarzana, CA.
On of our project was a ground up single family home built on hillside, that involved plenty of
excavation and grading, and specified foundation work. Gabriella helped us design a European- style
house with all amenities customized for us.
Our other project was a 3500 square feet full remodel and second story addition. Once again when construction
was finished by her group, she guided us through the entire remodel.
My husband and I can definitely recommend Flawless Design Group Inc. for any kind of construction work,
from remodeling , to addition and new construction.

Custom Home Builders FAQs, answered by experts

The average cost to build a modular home is around $270,000, and most modular homes total between $180,000 and $360,000. Of course, this price varies significantly by location, and the price tends to follow the cost of living in the area. There are quite a few other factors at play that can affect your pricing, including the following:

  • Number of bedrooms and bathrooms

  • Site preparation, including land clearing and leveling

  • Type of foundation

  • Utility connections

  • Cost of building permits

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

Building a new home can be more expensive than buying an existing one, depending on the housing market in your area. Many homeowners still find that building a new house is worth the investment as they can choose the exact layout they want, as well as to choose their own floors, wall coverings, appliances, and finishes. If you live close enough to the build site, you can also stop by to check on the builder’s progress, which can provide some peace of mind that the project is worth it.

One starting point to find a local home builder is to collect suggestions from friends and neighbors. However, it’s still wise to do some more research before you hire a builder. Read reviews to supplement any word-of-mouth recommendations. Check sources like Angi that have standards and criteria in place to screen the pros it lists can also help you find more reputable local home builders.

Yes, you can finance new construction, though the process often requires a different type of loan than one for an existing property. There are several financing options available:

  • Construction-to-Permanent Loan: This is a common option where a single loan covers the building costs and then converts into a traditional mortgage once construction is complete and you move in.

  • Construction Loan (Stand-Alone): This type of loan provides funding only for the duration of the construction project. Once the house is built, you will need to pay the loan in full, typically by securing a separate, standard mortgage.

  • Builder Financing: Some custom homebuilders offer their own financing options, which may only require a down payment to begin the building process.

  • Bridge Loan: This can be a useful short-term loan to fund your new construction while you are in the process of selling your old home.

  • Home Equity Options: If you are building a second home, you might be able to use a home equity line of credit (HELOC) or a cash-out refinance on your current property.

It's also important to be aware that some lenders may have restrictions on financing for DIY house builds, so be sure to verify that you can secure financing before starting your project.
