"We recently had our bathrooms remodeled by AI Construction, and the entire experience was absolutely outstanding! From the very beginning, Angel and his team were professional, honest, and incredibly easy to work with. They paid attention to every detail, communicated with us throughout the project, and made sure everything was done to the highest standard. Angel is a reliable contractor who delivers exceptional quality and an stress-free experience, I highly recommend AI Construction. We couldn’t be happier with the results and will definitely be recommending them. Thank you, Angel and the entire team, for bringing our vision to life!"

"Reese was reliable, he was there when he said he would be. He quickly made changes as needed. He suggested solutions to unanticipated problems. He not only acted professionally, he looked professional. I will never call anyone else and I have two more phases of my remodel to go."

"I just hired this company, haven't started the project yet, but for those whom came to give an estimation i was truly disappointed! Raul, came here took the time to check areas looking for soft spots in the floor, gave suggestions and solutions, and best and worst case scenarios. He had great ideals, gave me options and made me feel secure in knowing what his was doing and what and how they would proceed! That in itself speaks volumes! Others on here whom came were lazy, not looking or have a clue what kind of work was needed, yet spit out an estimate that made me laugh!! I will out of kindness not reveal their name! I will give more reviews as the project gets underway and done. I'll also post before and after photos!"

"I interviewed six solar companies and got bids from three. Charlie of Landmark construction & energy crew stood out much more above the other companies that I spoke and met with. He is responsive, always returned my calls quickly and he does what he says he is going to do. Charlie came over to my house and met with me before installation, during the installation and after. In addition he worked with his crew at the beginning of installation to make sure everything was perfect with a tricky area of my roofline. Above all of what I wrote above, Charlie and the office staff are very organized people. Charlie was able to provide me with a lot of information about rebates, taxes etc… and Every bit of information I could want related to monitoring my system, working with Landmark construction & energy crew, maximizing the cost benefits, and getting my tax rebate, are all gathered and clearly labelled in a binder. Charlie knew how to explain everything about solar and I could see during our meetings how much patient he have. Charlie didn't have to push anything in order to sell his work to me because his product was the one I wanted, it made sense, and the price was better than others. I can't think of a contractor and I've worked with quite a few once in the past and for this project, I met with several ones as well and Landmark construction & energy crew is more reliable, efficient, and customer-oriented. Thank you, Charlie!"

"Matt came to inspect our roof and found another tile that needed to be replaced in addition to the 2 that were already broken. He came the next day to do the job. In addition to replacing the tiles, he fixed other tiles that were previously repaired by another company. He was efficient and did an awesome job. Reasonable price and would use him again for any future jobs."

"I went with Expert Home Builders on a room addition. The big and expensive project and bog responsibility but I'm happy I hired this contractor. David and his team showed up on time and they were great from first day to end of this project. David was knowledgeable, honest and helpful. He informed me about working progress all the time and contacted me immediately if there was something important. His team worked hard, kept working area clean as possible, they were professional, friendly and quick also. The project was finished ahead of schedule and results are excellent. The quality of work is superb, overall experience excellent and price very acceptable. I would highly recommend Expert Home Builders to all people I know!"

"We loved working with Repair and Remodel Experts. They were
professional, polite, accommodating and stayed on task. They met our
deadline and the work they did was fantastic. Being a church, we
appreciated their work ethic and the demeanor of their crew. We didn't
have to worry that we would have visitors who might hear inappropriate
behavior or language coming from the construction area (which was right
next to our current office space.

"Ybarra Professional Builders did 2 big plumbing projects on my house and property. Not only did they install a brand-new main water line to replace the old leaking galvanized steel pipe, but they also re-piped my house's plumbing as it was also made from that same rusting out galvanized steel. I also had some other major work done by them at the same time (tree removal and sprinkler repair) but since Home Advisor asked for a specific type of project for this review, I will only review the plumbing projects. Vlad was the project manager for all of these projects. He coordinated all of the sub-contractors' work and got the projects done in a timely manner. There were none of the time issues that I had heard about with other contractors, such as waiting weeks between one phase of a project to get the next one started-after one phase was done, the next phase would begin with no more than a day or two in between. He was very pleasant and very patient with my many questions and concerns and kept me up-to-date with what was happening. The project that I most dreaded, the house plumbing re-piping, was not as bad as I thought it would be, to my great relief. All of the people who I dealt with at Ybarra were pleasant and professional, from the sub-contractors to the office staff. I think the quality of the work performed was very good. In the additional clean-up phase, the holes in the drywall where the plumbing had been re-piped were patched and painted, and the concrete where the driveway had to be cut to replace the main water line was re-poured. This portion of the project was available as an additional cost, but the workmanship was very good. I had heard and read many horror stories about dealing with contractors so working with this group was a pleasant surprise. Thank you, Vlad."

"Just had to drop a review for Result Construction after they wrapped up our kitchen extension. Honestly, I was dreading the disruption, but their team was so considerate and tidy. Every evening, the site was cleaned up, and they kept us updated with progress. The final reveal? My jaw dropped. It’s not just a kitchen; it’s the heart of our home now. Sacramento friends, if you’re thinking renovations, these are your go-to guys."

FAQs for addition to existing structure building service projects in River-pines, 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.
