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."

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."

Our Mission Statement: Long Creek Construction, LTD, is to create long term relationships with our customers, suppliers and employees by demonstrating honesty and fairness. We strive for excellence in workmanship and service through friendliness and efficiency.

We also have experience in many other miscellaneous construction fields. But, don't trust us just because of our experience, try us for yourself and let us prove to you what we can do!

"Amazing job! Carlos and his team of experts went the extra mile to ensure that I got exactly what I wanted. Carlos reviewed details of the contract with me and we worked together to make adjustments if I had minor changes during the remodel. Long Creek construction workers, plumber, and electrician were timely, efficient, and consistently worked M-F and on some weekends. The result of Long Creekâ s work is a beautiful 600+ sq ft bedroom and bathroom. The bathroom is absolute nirvana: beautiful black matte porcelain tile floor, a black porcelain tile accent wall and shower accent, with luxury polished cream tiled walls with hints of black within. The shower has 6 shower heads, including 1 static rainfall, 1 hand-held shower head along with 4 side-wall mounted pressure point shower heads. The mirror has a defogger button and three-way light dimmingâ seriously? On either side of the mirror are beautiful sconce lights. The Woodbridge freestanding jetted tub is the final touch to give the bathroom a total spa-like atmosphere. And the vanity has spring-loaded closures for the cabinet doors and drawersâ no detail was overlooked. Long Creek did a spectacular job increasing the size of the primary bedroom from previously 200 sq ft to over 600 sq ft. It features two walk-in closets, beautiful solid hardwood floors, a high ceiling with recessed lighting with dimmers. The ceiling fan is a top-quality 8000+ CFM beauty. The bedroom has a large sitting room that breaks up the space very well and gives me and my husband the feeling that we are in an upscale hotel suite instead of a bedroom. Long Creek Construction is a professional, efficient, team of experts. They worked every dayâ even days with inclement weather. They donâ t waste time, they are incredibly accommodating, and they do things right! I am so impressed with the level of regular communication, exceptional quality of work, and timeliness of Long Creek Construction. I am extremely happy with the work and ! will definitely choose them again!"

"Mr. Gomez and his crew worked quickly and efficiently. The final price was just 5% above the initial estimate, even when it involved some additional tasks not included in the original work agreement. The only minor issue that it took two weeks after the bulk of the work was done for the crew to come again to finish the final work. Nevertheless, I would be happy to hire Go Contractors again."

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.
