"Martin's got it done right, on budget and on time. Martin and Ivan were great to work with. We love our new bathroom and connecting room. They did drywall, flooring, toilet and sink/vanity install."

"Kevin and his team are fantastic in every way! We have a 200+ year old farmhouse that needed all of the windows and the front door replaced. We met with several different companies and only Inspired was able to meet all of our needs. And, the price point was at or below our other quotes. Throughout the process, Kevin kept in touch, provided clear estimates and answered our questions. The installation team was equally professional. Having to take windows up and down 2 flights of winding stairs was nothing short of amazing! I can't begin to say how pleased we are with the final product and Inspired's team. I highly recommend them and will be calling them back for our next project. "

"We had an excellent experience working with GJP Developers and are happy to recommend them. Gary gave us great advice about what could be done within our budget and offered suggestions that truly added to the quality of the outcome for the space we were working with. His staff have a superior work ethic and Gary checked in on site often to be sure the project was moving forward and consistently kept us up to date on the progress of the renovation. When we asked for some changes to the original plan he was courteous and patient in providing us with what we needed. We were really surprised at how quickly the renovation progressed and how the quality of work was maintained along the way. We highly recommend GJP Developers and would have no hesitation hiring them again for other home remodeling we are considering."

"We recently worked with H&Y LLC for an addition they built on the back of our home. Yokayra and Heber are definitely a power couple! From their expertise and professionalism to their workmanship and quality products, everything is always 100%. The crew is exceptional, and everyone works very well together. They also renovated our kitchen in the main house and it's absolutely gorgeous! Their customer service is superb. They are always available to answer any questions, address any concerns, and work with you and your budget to execute your vision. We are very pleased with their work and will definitely be using them for future projects. If you need quality work, seriously just give them a call. I promise you will not be disappointed! Thank you all so much!! "

"Very well! Everyone performed the work very well and cleaned up after. They added a sunroom for me last year and I had such a good experience with them that when we needed some kitchen renovations done, I called Andrew again."

"Jim and his team were very professional throughout and did an awesome job renovating our exterior porch that enabled us to proceed with our initial concrete project. Jim's recommendation in 3D allowed us to visualize the plans in advance and the end result was perfect for our needs. I will be reaching out to Lockhart Construction for future work and highly recommend that you do the same!!"

"This was the BEST experience we could have ever asked for! Wayne from the initial interaction was very personable, professional, transparent, friendly, communicative, knowledgeable, trustworthy and most of all, a good and honest person. We were very hesitant in hiring any contractor to complete our basement remodel but Wayne and Team put all of those fears to bed and delivered an absolutely well constructed, beautiful and comfortable space for our family to enjoy. The project was overall seamless and had a few challenges but nothing that Wayne could not recommend solutions to for a resolve. We were very fortunate to work with Wayne and would do so for all future projects that we may have - in a heart beat. We highly recommend BlueRidge Builders for your next project - definitely worth the time and investment to end highly satisfied with quality well constructed work in the end. Thanks Wayne, we really appreciate you and our beautiful new space!"

FAQs for addition to existing structure building service projects in New Castle, DE

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.
