"I was skeptical of remodeling our kitchen because you hear so many horror stories about contractors taking too long, charging more than they say, flaking out, etc. My husband and I were in disbelief at how OPPOSITE Pristine is from that. Pristine Construction is exceptional. I don't think I have ever encountered a better company.... and I have very high standards! Nathan and Mike are not only true to their word, totally professional, and incredibly knowledgable, but they are 2 great guys who are fun to hang out with! They make you feel like you are their only client. Pristine Construction really does care about you as a person and they take a great deal of pride in providing the best service and best quality work. Also, the designer they had design our new kitchen was incredible. The layout of our finished kitchen is gorgeous. We are extremely happy with everything Pristine and their sub-contractors did. Our kitchen remodel was worth every penny. Their price was reasonable and similar to other construction companies around. Nathan and Mike and their crew helped us better our lives and we are eternally grateful. You will not find anyone better in Los Angeles!"

"We had converted our half bath into a full bathroom. Bridgestone construction offered accurate timelines, competitive pricing and committed people to complete the work. They also handled all the paperwork and permitting and followed up with our local inspectors so that the work could be completed on time. They were extremely clear at all the milestones and payments were structured after the work was completed. Their people kept to covid protocols (taking temperatures everyday, masks all the time, daily record of everyone who was working), and worked with very high quality. Jeremiah was a pleasure to work with, He did a great job of minimizing disturbances to us. They were great at adapting to all the various issues that came up to ensure the job was completed on time with high quality."

"My relative has been living in the same condo for over 50 years and finally agreed to have the junk acquired hauled away. During this process mold was found in a bedroom and kitchen wall. Al, the owner/manager, had given me a reasonable estimate in the beginning, and after finding the mold, another reasonable estimate was given. All work done was professional and on time. One full bath had a new floor installed and a new toilet installed. One bedroom wall needed new baseboard, installation, and painting. that bedroom needed new carpet installed. One kitchen wall was sanded and painted. Whole condo was deep cleaned. All work was excellent."

"So Cal Builders & Design Inc made the entire building process stress-free. They were transparent with costs, delivered work on time, and ensured every design detail was perfect. I couldn’t be happier with the final results."
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.

"We just finished a four bedroom/ three bathroom full remodel in Santa Monica. We are very happy with the end result. Nathan, who is the owner, was very involved in all phases of the job. Nathan got the job done on time. The workmanship and attention to detail was great. He had good communication and relationship with his team. Whenever we had a concern or question, Nathan was easy to get a hold of and handled it quickly. We were worried about the process of a remodel with all the stories you hear about bad experiences. But Nathan made this so easy on us and we would definitely use him for any future projects."

"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."

"I needed a new house built on a complex foundation. Construction Masters did an amazing job from start to finish. Mickey and Moshe listened to everything I was looking for and worked with my vision to turn it into a reality. Their attention to sight lines and details are excellent. Mickey took me through all the work of choosing lights, cabinets, fixtures, etc. The two of them work so well together! Mickey and Moshe were there every day of the week to provide oversight on the project. The philosophy of the company is one of excellence and honesty. I do not know this because it is on a website or brochure; I know it because I had the pleasure of being their client. If they create anything, from a stair banister to a luxury bath or a whole house, it will be done to the highest standards. The work they did building the whole house was so superb that when they finished, I asked to be their client again without considering any other builders. I am going to build an ADU on the other side of my property and it will be built by Construction Masters."

"Very well. Mike did a full bathroom remodel for us in 2018 and basically stated he would take care of anything for us in the future if there are any issues/failures in the work.... which sounded too good to be true. He was the most expensive of the 3 bids we had for the bathroom, but also the most confident and clear in his explanation oh how he would help us, so we went with the "premium" option and chose him. Almost 2 years after the remodel, a part of the shower door broke and it was due to the glass company Mike hired that didn't drill a piece in properly, and instead used silicone, which eventually wore away. Mike was happy to send someone in for us to properly drill, but since it was April, 2020, and just into the pandemic, my wife wasn't ready to have a stranger in the home to fix it. Mike said no worries and just to let him know when. Fast forward to Feb, 2021, and I call Mike and he sends a guy 2 days later who uses a special drill/tools to take care of the minor issue that required special tools i didn't have. If you want quality, consider Mike and MF Construction, recognizing you get what you pay for."

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