"The KN Remodeling team did an excellent job at our home completely remodeling 3 bathrooms, painting our entire home and rebuilding a huge planter outside. We trusted them in our home while we are out of town almost the entire time. We hired them back to do additional work in our home that they did quickly and expertly. The team was professional, very friendly, worked quickly, quietly, cleanly, and I would highly recommend them."

"My husband and I really enjoyed working with Ben and his team at Creative Home Remodeling Group. Ben oversaw everything from making the plans, getting them approved by the city, scheduling the entire build and doing all final inspections. We really appreciate how communicative Ben was with what day and a time window we could expect the different work groups to come and what work would be done those days. If my husband or I ever had questions or problems with anything that was going on during our construction we were encouraged to call Ben and he helped create a solution that was workable for all of us. We liked that Ben and his team took care of everything from beginning to end and we did not have to hire any additional contractors along the way. We did have to purchase the specific fixtures and tiling we wanted.) We added apx 200 sq feet to our home, which included a bathroom, walk-in closet and room extension. The total process took exactly 1 year from signing our contract to us being able to use our added rooms. (That included making the plans, getting them approved by the city, the build, the installation and final walkthrough with the city inspector.) I would recommend using Ben and his team at Creative Home Remodeling Group to my family and friends. We look forward to working with Ben again in the future."

"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.

"To hire a contractor who started out in the Plumbing business could not have been a better choice for a bathroom remodel. Everything went wonderfully. They knew the law so I was able to do things correctly. They had ideas that even I did not have, having dreamed about this for a few years. The contractors son, who was also a licensed contractor was the main person on the job and here every day. I would HIGHLY recommend them. The price was fair and competitive."

"Trig Builders is an excellent one-stop shop for mainly excellent design, great help in selecting final materials/accessories and mainly for any complete home remodeling. Our master bathroom and kitchen needed to be completely demolished and redesigned. Yossi met with us several times and by listening to us and to what we want to get, he was able to come up with a new concept that included all the ideas and goals of what we wanted to have and his design was very clean, modern while still be within our budget. Yossi also managed and handled all the orders and purchased of the materials and final accessories which caused us to write this review because this was an excellent service. The bathroom was gutted and after the demolition, Yossi and his guys discovered that the floor support beams were damaged so we had to replace them with new ones and to have the floor leveled before they could start the new construction. This problem caused the budget increased by a small cost (Yossi charged us only for the materials) for the overall budget. All the professional people that were involved in the work including the plumber, drywall man, electrician and tile man were excellent and skilled people that executed their part in a very high level of work results. They were very careful about all the cleaning aspect by dropping cloths, plastic wraps for the floors. The kitchen was completely redesigned and Yossi was able to include everything we wanted and needed. He went with us prior to the work and helped us purchasing all the materials appliances. The remodeling job was a week behind the original schedule because of the floor problem and due to few days when we had to leave the house for personal reasons on top of complications in getting the necessary inspections completed. We must mention here that any of the delays was not caused because of Trig Builders fault. We are very happy and satisfied with Yossi, the workers and all the skilled people and mainly Trig Builders as the company and we highly recommend them."

"My wood balcony has termites and water damages. So I hired RET to do the job. Kevin gave estimates and recommended composite planks for floor and red woods for railings. His workmanship was very professional and finished on time! On top of that, Kevin updated my balcony to the latest building codes. His price is very reasonable. If you want cheap prices and lousy jobs,hire someone else! Highly recommended!"

"I was referred to 800 Remodeling by Angie's List, and the owner, Amir, called me literally minutes after I received the referral. I described my situation to him and we scheduled a meeting at my home for the following day. He arrived promptly and immediately introduced himself with a picture ID and his state contractor's license. After inspecting the cracks that were of concern to me in a structural post supporting a major beam, he took some pictures and promised to get back to me with some recommendations. The next day, he called just as he had promised, told me that after talking with a structural specialist he did not believe the post needed to be replaced, but nevertheless gave me a rough-order-of-magnitude estimate on what a replacement would cost, should I decide to have that done. After some additional research, I concluded that the cracks are typical and not impairing the structural integrity of the post, and decided for added insurance simply to reinforce the post with some wrap-around steel bands. Since that is a small and simple job, Amir offered to refer me to someone else to do that job for me. He did not charge me for the consultation or the time he spent in discussions with other specialists. So although I ultimately didn't hire him for this job, I was impressed by his professionalism and shall definitely be contacting him again for some larger jobs I am planning in the future."

"Dealing with contractors is never easy, and Ben is no pushover, but with very few exceptions, Ben and his crew do what they say they are going to do when they say they are going to do it, and they do it very well. What else can you really ask for from contractors. He's organized and a person of integrity. I liked that he sent a Google chart with supplies to purchase that we could work together that helped me figure out what kind of parts and tiles to purchase. Great experience and our bathrooms are amazing."

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