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."

Remodel Max is a full-service family-owned and operated design-build remodeling company that you can rely on. Servicing parts of Maryland, and Pennsylvania with a local neighborhood smile.

"My family & I were very pleased by the work we had done by Remodel Max. Shout out to Wayne, Dennis, Madison, Mitch, Brennen, & Nick. I was seeing signs in our 75 yr old house that indicated to me that the house might have been sinking, so we called out several contractors. I asked each contractor to bring a structural engineer along for the inspection, & Wayne was the only one who was willing to accommodate that. He was also the only one who could see the extent our floor joists & triple beam were deteriorating, was able to list the myriad of issues we had, & in each way it needed to be repaired. He was very thorough in his inspection. The repairs to the house required us to move out of our house while they rebuilt our entire first floor (+jacking up & re-leveling the house). Mitch & his crew handled it well, to put it lightly. Each of them went the extra mile & took time to make sure everything was done correctly. They were all extremely communicative, professional, & down-to-earth."

"AES Builder & Home Improvements Inc. was absolutely amazing to work with from start to finish! They remodeled our original kitchen, and the results are beyond beautiful. From our very first meeting to the day we spent picking out custom design materials, the entire process was organized, collaborative, and enjoyable. Their coordination and communication throughout the renovation were top-notch! Every contractor who came into our home was professional, respectful, and genuinely cared about their work. They answered all of our questions and kept us informed every step of the way, even when there were small delays. The quality of the craftsmanship truly shows, and our new custom kitchen makes me smile every single time I walk in to cook. We couldn?t be happier with how everything turned out.

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

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.
