"I hired Landmark construction & energy crew for a 650 sq/ft. of living room addition. Before we hired them, we already had all the necessary plans on hand including all the secured building permits with the city. When it comes to workmanship and speed, I must admit that landmark construction was very fast while investing extra attention to perfection. All the teams of workers worked fast even when it came to fixes and adjustments. They replaced the wood floor with new engineered wood flooring, repainted the entire ceiling and one living room wall and blended new stucco on the exterior wall. The new addition required new foundation, framing, and window installation. We are thoroughly content with all the work that was completed by landmark construction & energy crew. 1) they made sure to cover everything all around the working area in order to prevent damages and extra work due to paint spots and dust from all the sanding. 2) They came to work on a daily basis and few times they skipped work BUT they made sure to confirm that 2 days ahead. This was very responsible from them to do. 3) Charlie the Project Manager was available and reached all the time. When he couldn’t talk or answered, he called within the hour. In regards to pricing… the price that we got from Landmark construction & energy crew was in the middle range. Charlie came over to the house several times to discuss about the details and the process of the project, and after that he start working on the estimate."

"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."

"Ask to work with Rafael, if you're in Seattle, he's a true professional. He takes pride in the relationship he builds with his customers and has a team that is meticulous and extremely fast. They came in and painted the exterior of my home and the quality of the team's service was nothing short of outstanding."

"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."

"Johnathan and his workers were professional and knowledgeable about the work that needed to be done. It was a pretty straight forward job but we needed the work to be perfect, Johnathan assured us it would be and it was! The guy who did the work was polite and cleaned up everything perfectly when he was done. Thanks, Johnathan!"

"It is a waste of money. The great majority of people are not going to find any value out of the service. If you need design consultation, you need a full service consultation. If you already have knowledge and experience, and you just need to get a few ideas, then you don't need to pay for that. You can just get a magazine or a book since you already have the knowledge of basic designs in your head or a little bit of experience. To have someone call you and give you information over the phone, you are not getting the personal service that you need. You may as well take the money $49 and apply it to something else like getting someone else to come out and give you the service that you need. Because, you are not getting much, you are not getting anything at all. They are going to have you do the work. After talking to them and I was talking to other home designers, I found out that that was a waste of time and waste of money. I gave them a C because they didn't fail at what they do but they don't offer any value for what they do. There's not much value to it. The cost was fair. They didn't do a terrible job and the cost isn't terrible, it was only $49. It just has a very low value. For responsiveness I gave them a B because they will answer your phone and answer your emails."

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