"The remodeling of my guest bath went very smoothly. I had few ideas as to what I wanted, but thanks to Nathan's design help, I was able to select the items that fit my concept. Many reviews talk mainly about the job and the results, but there is one important area that is often neglected: the working crew. Without exception his guys, besides being highly competent, were both respectful and considerate at all times. I strongly recommend this company!"

"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."

"Working with Nathan & KN Remodeling was the best decision we made when undertaking our garage conversion job. Nathan understood exactly what we wanted, knew our budget parameters and provided us with a range of options that helped us stay within what we were seeking to spend. We wanted it to be NICE, but didn't need to over-do any of the finishes and spend needlessly on areas that were going to be used in-frequently. The end result was fantastic. The workmanship was of the highest order, the job was executed efficiently and with constant communication and oversight. The whole job was stress free and delivered on time. I can't recommend KN Remodeling highly enough!"

"If you need an addition built on your house, I'd highly recommend you give Creative Remodeling a call. We used them to add a master suite which makes our house much more livable. We've also decided to add decking in the back yard off the the back of the house. Oh, and this was after working with them during Covid on a kitchen and 2 bathrooms. So that makes us repeat, on repeat, on repeat customers. The work is quick, to a good quality, and they listen to what the customer wants and have dealt with the odd snafu without any push back. Highly recommended."

"Our bathroom was unusable when we bought the house, so we decided to completely gut it and start from scratch. 52 Star Construction were an amazing team from start to finish. The whole project was completed to a high quality. The excellent communication through every stage of the project made it less stressful for us knowing we were being looked after. I would highly recommend 52 Star Construction to anyone wanting to renovate their home."

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