"The experience of working with Pristine Construction greatly exceeded my expectations. At least one of the owners was on site every day, and from the moment construction started they did not skip a day of work. Everybody was friendly and knowledgeable. I can't imagine hiring another company 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.

"It went exceptionally well. The Project Manager, Jonathan, was very knowledgeable and patient -- it took us a couple of months to get ready for the project. Jonathan is reliable, competent, easy to work with, and will make sure the job gets done right. He and Supreme Remodeling, Inc. would make a great choice for your next renovation or new construction project."

"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."

"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. "

"We needed to do a kitchen remodel for a while now so we did a massive research online and by asking friends and family in our area. After meeting with all of them and explaining to them what are we looking for, what we want to do and mainly what is our budget. We received estimates from all the contractors that we met and we selected Trig Builders because Yossi was the most competitively priced and the referrals that we got on him and his company were very positive. Yossi and the workers were very easy people to work and to deal with and Yossi designed the kitchen exactly the way we wanted it with some nice additions of things that we didn’t think we will get. His suggestions about the new kitchen layout, where and what materials to buy were very helpful. Also, his advises and recommendation on where to buy the cabinets, lightings, plumbing and appliances saved us a lot of money. The end result of the new kitchen was perfect and one of the things that added a huge plus before we hired them was the warranty that included in the price of the work that they did."

"My husband and I hired A&A Construction for multiple projects in our condo: fireplace modernization, laundry room conversion, bathroom renovation and living room cabinetry build-ins installation. The scope of all projects required a lot of design and planning, ranging from cabinetry design to running electrical and plumbing connections, and so much more! The results are stunning. Our place looks like a completely new unit that someone just built. Arnold and Devon are knowledgable and experienced consultants who gave us lots of ideas on how to improve our place and give it more function. The entire team was professional, courteous and punctual. They catered patiently to our requests as we made some changes during the entire renovation process. Overall, we had a great experience working with the A&A team and we would hire them again in the future. "

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