Here at Embee & Associates, Inc., we pride ourselves in a job well done. With an eye for detail, we will help your dreams become realities so please contact us today for a fast and friendly service that you will not be disappointed in!!

"Overall my experience with this company was great! The work that was done was really really good! Our contractor who assisted us was Jose. We added a living space and master bedroom to our home. The additions done look as if they were part of my house this whole time. Honestly it looks way better than I expected. The only reason I rated the company a 4.5 was because there was always some kind of miscommunication between our contractor and his workers. Don t get me wrong, things were always resolved, Jose was great at that. But my recommendation to is to make sure communication is #1. That way the customer is not confused or left wondering what will happen next. There was an issue with his floor guy though, he was rude and unprofessional. BUT the reason I am mentioning this is not to put down the company but let you know that we expressed concern for this issue and it was resolved professionally by Jose and it never became an issue again. The quality of work was top notch! His workers were all pretty cool guys and we always felt comfortable of who was coming into our home to do the work. I highly recommend this company for your next big project😊👍🏼"

FAQs for major renovation multiple room service projects in Ontario, CA

The 30% rule serves as a guideline suggesting that renovation costs should not exceed 30% of your home's current market value. This principle helps prevent over-investing in improvements that the market may not fully reward upon resale. 

For example, if your property is valued at $200,000, keeping your renovation budget under $60,000 provides better financial returns. However, this rule should be balanced with your personal goals and how long you plan to remain in the home.

A $50,000 budget can effectively transform several spaces if carefully allocated. This amount covers a moderate kitchen refresh combined with a bathroom update, or several less complex rooms like bedrooms and living areas. 

Your geographic location, material choices, and the extent of structural changes significantly impact what this budget can accomplish. Focusing on cosmetic improvements rather than major layout changes helps maximize your investment across multiple spaces.

Labor constitutes the largest expense in multi-room remodels, accounting for 40% to 70% of total costs. Kitchen and bathroom spaces demand the highest investment due to their specialized fixtures, cabinetry requirements, and necessary plumbing work. 

Premium materials such as natural stone countertops, hardwood flooring, and custom cabinetry also significantly increase project costs. Strategic budgeting that balances splurges and savings helps manage these high-cost elements effectively.

Most multi-room remodeling projects require three to six months from start to completion, though complex renovations may extend longer. The process follows a necessary sequence of demolition, structural work, mechanical rough-ins, finishing, and final detailing. 

Timeline variables include material availability, contractor scheduling, inspection delays, and unexpected conditions discovered during construction. Establishing clear communication with your contractor and making prompt decisions helps maintain momentum throughout the project.

Begin with foundational and structural modifications that affect multiple spaces before progressing to individual rooms. Address "wet" areas like kitchens and bathrooms next, as these involve the most complex work with plumbing and specialized installations. Complete bedrooms and living spaces last to prevent damage to newly finished areas. 

This logical progression minimizes redundant work and creates at least one functional living zone throughout the renovation process. Coordinating related work across different spaces also improves efficiency and potentially reduces costs.
