We pride our company on reliability, great communication, integrity, and quality work. We strongly believe in giving our absolute best in all of our projects no matter how big or small. We are experts in our trade and will always keep you educated on your particular task or project. We look forward to earning your business!

"All the people at Elevate Design and Build were amazing and a pleasure to work with. We doubled the size of our house including tripling the size of the kitchen, knocking out walls to create an open floor plan and added a three car garage with home office over the garage. They even recommended modifications to our original blueprints which were excellent. All their workers friendly and did a first class job. Went totally above and beyond our expectations. One year later we have not had one single problem with any of the work. Total integrity. If any issue came up, the company absorbed the cost - not the customer. Everything they did was done perfectly. We didn't have a single issue or complaint during the entire process. I give them my highest personal recommendation. I would never use anyone else."

Managed Renovations engages with our clients using a couple different business models depending on their needs, preferences, and level of desired participation in some of the required tasks involved with most projects. Some of our clients choose to use our unique construction management services business model to build their project that is distinctive from the typical fixed-price general contractor (GC) approach to construction. For those clients we provide fee-based construction management consulting services to schedule, manage (on-site), and review all the work that our clients choose to have us handle for the project. We connect and contract our clients with our seasoned collection of licensed and insured tradesmen and subcontractors (and our own in-house carpenters) that will provide each of their fixed price costs. Alternatively, some of our clients prefer to have their project built using a typical fixed-price general contractor (GC) approach to construction.

"We recently had our kitchen remodeled by Managed Renovations. The experienceâ from start to finishâ was nothing short of amazing and the finished kitchen is spectacular, exceeding our expectations. The Managed Renovations team, Michael and Natalie, and their subcontractorsâ carpenters, electricians, plumbers, and floor installersâ displayed a level of professionalism, craftsmanship, and attention to detail that was extraordinary. They turned a small, poorly designed 1970s kitchen into a large, beautiful, functional space that is now the heart of our home. Although the project involved demolishing walls and removing the existing cabinets, appliances, and flooring (and replacing them with new cabinets, appliances, and flooring), they accomplished this with minimal disruption to our lives, always leaving our home and the work area clean at the end of the day. Managed Renovations communicated with us throughout, (we could also track every aspect of the project online), making sure we were comfortable with every decision. Their recommendations, whether about design elements or vendors, were always â spot on.â There were no surprises. They delivered what they promised when it was promised, completing our kitchen on time and without any unanticipated costs. Managed Renovations' dedication to excellence and customer satisfaction is truly unmatched. If youâ re looking for a general contractor who will deliver outstanding results, look no further than Managed Renovations."

Here at Best Homes, our company is based on the belief that our customers' satisfaction is of the utmost importance. Our team is driven to meet your needs with professionalism, creativity, and efficiency. Established 2005. Owner: Jonathan Perez Office Manager: Paige Marie Campbell Project Manager: Jefry Perez

"Basement Project We absolutely love our new basement! I was very nervous when selecting the contractor for this job. I interviewed three contractors for the job, all seem very decent, but what set Best Home apart was Jeff Segovia. He designed the whole layout of our basement (we love it) and oversaw the entire project from beginning to end. The construction crews were very polite and friendly. Best Home did an excellent job and very flexible with many changes I had and they completed the job on time (took 3 months and exactly 1 week)which was amazing. I am actually hiring them again for additional projects. I highly recommend Best Homes!"

FAQs for addition to existing structure building service projects in Ashton, MD

Yes, hidden rooms are legal, as long as they meet all local building regulations. If you sell your house, most states require homeowners to disclose full houseplans, which would include any hidden rooms.

If your secret room is a safe room, it should contain a means of communication aside from a cell phone, such as a shortwave radio. You should also have plenty of drinking water, a portable generator, emergency food supplies, blankets, pillows, flashlights, batteries and a first aid kit.

Any time you update your home’s square footage, you increase its value, but a secret room is a niche feature that doesn't rank high on every buyer’s list of must-haves. Investing your money in remodeling more common living areas like bedrooms, bathrooms, or kitchens will have a higher ROI than adding a secret room. Many secret rooms can act as entertainment spaces (think a game room or wine cellar) or quiet spaces (a library or study), so when building your secret room you may want to consider its versatility for when you’re ready to sell.
