"Our initial meeting with Suj was great. Initially, we had in mind a much larger job. He had quoted us $3000 for the closet demolition / wall rebuild (non-load bearing), packaged with several other items. Together with the fee for drawings ($4000) and permits, this was a bit higher than we anticipated. However, we decided to go with Suj due to his responsiveness and professionalism. Out of our other quotes, Suj’s pricing was middle of the pack - not the cheapest or most expensive. When the drawings were complete and evaluated, he gave us an updated cost of $6000 over text message. The scope of work had changed, and this was no longer part of a bigger project - understandable. The issue was when he gave us the official estimate a week later and up’d the price once again to $9000. When asked what happened, his exact words were “well, I need to get paid too”. He had weeks to consider before quoting the $6000 and nothing had changed since then. The extra $3000 may be insignificant compared to most renovation costs, but for us in our first home, this was back breaking. We continued with Suj since we were already locked in and well past the 3 day cancellation period. Their work for the most part was exceptional. The new wall blended perfectly into our existing structure, and the ceiling patch was also well done. The problem here was the floor. They had dug up a 1” deep pit in the floor, likely to remove the wall studs. However, they did not patch the floor or even let us know this was going to be an issue. We were never told about the pit until I decided to check in on their progress one day towards the end of the wall build. This required us to pay a handyman to come in next day on a weekend to patch the concrete since we had cabinets being installed the following Tuesday. Suj was aware of this and did not believe it pertinent information. Overall, Suj and SoCal Builders do quality work, but the issues in pricing consistency lost us before the work even started. Not even telling us that we’d be left with a 1” deep pit in our floor after was another huge issue which should’ve been brought up much earlier. This was our first experience with a contractor and I’m not sure if this is typical or not. However, it’s enough to make me doubt I’d contact them for any future work."
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.

"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."

"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."

"Skykine Konstruction really does “take the con out of construction”! They provide transparent estimates, and their team of pros for every trade is well versed with building codes, to do the job right the first time with zero issues during inspection. Juan and his team converted our attached 484 square foot garage into a beautiful, energy efficient ADU that “looks like it was always there”! Juan corrected mistakes made by the architect and added upgrades to our foundation required by the county, all with sensible solutions at minimal cost. Juan has attention to detail that will catch small things the average person, including the homeowner, will overlook. He is never satisfied with “just ok”….he aims for and achieves perfection! We actually missed him and his entire crew when the job was finished! They were all very friendly, yet professional in every respect. Don’t trust just anyone with your hard earned money and family home. You NEED a trustworthy leader like Juan, who will give you a fair price for exceptional work. Don’t trust a company that sends a representative that is only good for pricing at the high end to collect a commission! Cut out the middleman and go direct with Juan. He has my number and knows he can always ask someone to call me for a real life and honest assessment of him, his work and company. A home is never done, and we’re glad to have Juan as “a friend we can trust”, for all future projects. And for the record we did not know him until we awarded our project to Skykine, so that says a lot!!!"

"Jorge, Andy and their team at A1-Builders were knowledgeable, honest, reliable and above all always available to answer any questions we had. They helped build a 2 bed 1 bath 600sqft addition to our home during the lean months over the pandemic. We had multiple projects (pool, patio, retaining wall) going on at the same time with other contractors and the crew from A1-Builders were by far the most professional. They always made sure that they left their work site clean after each dayâ s work. Jorge will definitely be the first person I call for our next home project because I know that even if he does not have the time to do the work, he will always guide me in the right direction. Thank you again to the entire A1-Builder team!"

Customers say: True professional

"We found McCormick home builders through Angie’s list. They were not one of our original contacts, but they contacted us and came out to give us a quote. Matteo was extremely helpful, informative, honest, and gave us reasonable realistic prices, and did not try to inflate the prices or pressure us in anyway. We felt very comfortable with him immediately. We felt like he was a member of the family that we could just talk to and ask questions he was very personable. He gave us his contact number in case we had other questions and he was always available when we needed him for any type of questions or concerns. Mateo‘s team did a beautiful job. They were fast. They were efficient. They cleaned up beautifully. They did a wonderful job. They were very considerate of our time our needs and our neighbors. They were an absolute pleasure to work with. I would highly recommend Matteo from McCormick home builders for any home building projects, and we will be calling him again in the future!"

FAQs for addition to existing structure building service projects in Diamond Bar, 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.
