"Ultimately the work performed was high quality. When there were small finish issues, the team came back and fixed everything to ensure continuity with our existing home design. The timeline overran a bit, but the workmanship was great"
Completely renovating both the guest and master bathrooms. In the master bathroom, we're installing a spacious walk-in shower featuring dual black-finished shower heads, elegant floating benches, and marble wall tiles. Meanwhile, the guest bathroom will have a sleek built-in tub and stylish hexagon tiles.
This project involved adding a new master bathroom to the existing house. The shower features sleek white subway tiles complemented by striking black fixtures and shower door hardware. The bathroom floor is adorned with elegant white marble tiles, providing a seamless and luxurious finish. A white shaker vanity topped with a white marble countertop completes the space, creating a clean and sophisticated look.

"Nathan impressed from the time I first met him. He was far more professional than other contractors in terms of describing how his company works and what I should expect if I worked with him. He also has a nice showroom where you can look a variety of cabinets in different styles and colors as well as countertops. We ended up getting a countertop that he suggested. We would never had picked it on our own but it ended up looking amazing in our kitchen. We had him do a complete remodel of our kitchen and one of our bathrooms. The guys on his crew were always prompt and showed up as scheduled. His foreman was both a good communicator and listener. Whenever we ran into an unexpected issue, they communicated clearly what additional costs would be involved (if any) and how much additional time it might take. The cabinets he installed were custom made but did not cost more than the pre-fab ones you can buy at the large home improvement stores. They are of high quality and well constructed. I actually saw his cabinet guy using a small caliper to make sure the door distances from the cabinets were all even! Lastly...here's something you'll never hear about a contractor...he finished AHEAD of time! Nathan's company are straight shooters and very skilled craftsmen. I would work with them again."

"HIC builders is a family owned company, and they did a terrific job at my house. We added an ADU above the garage, remodeled two bathrooms, and did other extensive work on the house. Abraham, the field manager, was responsive and available, flexible when plans needed to change to accommodate structural issues that we discover as the project progressed, and answered my endless questions. The workmen were always on time, courteous, and cleaned up the site every day before they left. Probably the easiest way to find out if HIC can provide what you want is to call Abraham Moryossef directly (818 850 5062) and chat. I know it will be a good investment of your time. They are terrific!"

"We are working with Guy to convert our garage into an ADU/pool house and it is going great. I'm always impressed by the quality of work that Guy and his team at Supreme demonstrate -- and very pleased that they are able to live up to the timeline that he commits to. They are able to work well and quickly, and at a fair price. This is a big project for us, but Guy has walked us through each step so we know what we need to do. This is the second time we have worked with Guy and he has delivered well on both projects he has worked on with us. If you're looking for someone to take care of a remodeling job for you, I would strongly recommend Guy."

"Relationship Building and Strategic Thinking are how I would describe Home Renew 360. This was my 1st major home improvement project. Viktor Hohlov was my project manager and he has been beyond fantastic. He kept his promise to be with me from day 1 of the project to the end. Adaptability, connectedness, developer, harmony, individualization, positivity and relator are how I would describe Viktor. He heard my comments and concerns and communicated that to his team and contractor. He was constantly checking on the sites and showed great accountability to ensure services and jobs were being done with high standards. Idan Mizrahi was my contractor for the project. Idan and Viktor work amazing together to make sure that I was satisfied with the outcome of what was being done. He was accommodating in meeting with me and showed me a short clip of a video of the whole process of each work. Analytical, strategic, focus and communication were Idan’s strengths. The team that was working on my houses were friendly, respectful and accommodating. They were there on time and cleaned up at the end of the day to ensure safety and cleanliness. My tenants who live there have reported how pleased they are with the crew and the communication they received. The houses look amazing with small details that they were able to exceed beyond my expectation. When you are ready to do your home improvement project, contact Home Renew 360 I highly recommended that you work with Viktor Hohlov and Idan Mizarahi."

"Our kitchen was in dire need of upgrades, and we met with many different contractors for estimates. Young from New Life Construction left the best impression by far, from his professionalism, renovation ideas and design, reasonable pricing, etc. I am so glad we decided to go with New Life as Young and his entire team were a delight to work with from start to finish. We received very helpful opinions regarding many aspects of the design and materials without it being overbearing, and it was helpful to see his previous projects through instagram (@newlife_construction) to see what has worked well for similar kitchens in the past. There was clear communication about everything from details of the job to scheduling and everyone was very attentive to our needs throughout. This company handled the demolition, cleanup, cabinets, countertops, overhead lighting, painting, appliance installation (range/oven and dishwasher), sink and faucet installation for us-- pretty much everything in the kitchen except the floors. They bring in separate contractors that are specialists in their respective field (cabinets, countertop, etc) to do each portion of the project so you know you're truly getting the experts at every step of the way. Even after the project was done, Young went above and beyond to wrap up last-minute issues that came up from cabinet parts that were on backorder and to this day is responsive to any issues that may come up in the future. My family and I are so happy with how the kitchen turned out and we would not hesitate to hire Young and his team again for future projects."

"Skyline construction did an excellent job. Juan Munoz was a great contractor. We wanted to build an ADU but didn’t know who to trust. The workers were neat and careful. Every worker treated us with respect and we’re very friendly. I would highly recommend them to any of my friends or family."

"Recently completed a 2 bathroom remodel for my parents really old home. There was no high pressure tactics to remodel to something fancy when I was looking for functionality for the remodel. The quote was very detailed so I knew exactly what made up the cost of the remodel (materials, labor and estimation for permits). There were a couple of adjustments made along the way that either I requested or were unforeseeable because of the age of the home. But I was consulted and fully aware of any changes that were going to change the quote and the increases were small and fully approved before made. Workers arrived on time, wore masks and cleaned up after themselves each day before they left. I would recommend Skyline Konstruction and plan to use them again for the next upgrade we plan to make."

"I was totally wrong in thinking that this company would do a good job because in reality they did something spectacular, the entire work team was very kind and attentive to our family, we are a family that does not open the door to anyone but we decided to trust American Professional Builders, Jose was very friendly and understanding with all of our needs, he always tried to adapt the work to each one's style, my children's rooms are comfortable, elegant and at the same time they can play and have fun with the design that Jose created especially for them, our yards are safe for the children and at the same time we can enjoy a weekend with the wonderful Deck with fireplace and kitchen, the pool with games that Jose recommended and that he built is beautiful and fun for the family, the type of tile he used looks luxurious and the pavers he installed with the artificial grass around it were exactly what we dreamed of, we are going to build an ADU soon and we are already working on the pl"

FAQs for addition to existing structure building service projects in Walnut, CA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
