"Karol is a very nice guy to work with. He is approachable, easy to communicate with. He goes through the project from end to end on our first visit, explain how he would build the frame, cut the wood, the timeline. He also finds a stone guy and coordinates the work. When actually doing the work, he puts cardboards on our floor to avoid scratching. Upon request, he also did a prototype for us, and when we change our mind to use a different style, he redoes the bulk of the project. I would recommend Karol to anyone who needs carpenter work!"

"As most of us know when we do a remodeling project, it is real hard to find good and honest people to complete your project. Fortunately, I found Leo and Yonathan from SkyTech Builders to help me with remodeling and repairing two of the bathrooms in my family's 4-Plex building. They were very honest, polite and helpful each step of the process from start to finish. The are very patient and suggested materials and design but always thinking about quality and your budget. Overall the experience with Leo and Yonathan was top notch and we were very satisfied with the finished product. We will definitely be using Sky Tech Builders for our future construction projects."

"Tool Time was absolutely fabulous. Extremely professional and thorough. From beginning until end, everything was outstanding. No detail was overlooked. This was a step down for my mother‘s home, she couldn’t be happier. It looks as though it was installed at the same time the other banister was. 100% GREAT JOB !!!"

"I worked with Ilan Sigura about 16 years ago for remodeling the house my wife and I purchased and for remodeling a rental property we own in the bay area. We were very happy with the service and the quality of work. Since then, we left the bay area moved to Southern California. But a few months ago the tenant in our rental property left after 12 years and we decided to do extensive work to bring the property to a better condition. Naturally, I reached out to Ilan and asked him to handle the project. I entrusted him to do the work and make some decisions on our behalf since we are not local. Sigura Construction did an excellent job. They met the cost constrained we gave them, and met the timeline committed to us. The quality of the work is exceptional, the attention to details is great, the suggestions they made were very helpful. Overall, we are extremely pleased with results. The house is now rented and the tenant is very satisfied with the condition of the house. I definitely will continue to use them in any future projects!"

"Jorge did an outstanding job remodeling both of our bathrooms and replacing all of the water pipes throughout our house. The quality of his work was excellent, and everything was completed professionally with great attention to detail. Jorge is reliable, trustworthy, and extremely responsive. He kept us informed throughout the project, addressed our questions promptly, and always followed through on his commitments. He is someone you can truly trust to do the job right. On top of that, he went above and beyond by replacing a few additional items at no extra charge, including our kitchen sink and several shutoff valves. Those thoughtful extras showed that he genuinely cares about his customers rather than just finishing the job."

FAQs for addition to existing structure building service projects in Redwood-estates, 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.
