"Joe completed multiple projects for us. He was friendly and easy to work with from the start. Went above and beyond in regards to finding us windows that would work without having to wait months for them. Communication was excellent. Fairly priced. We are so pleased with his work, highly recommend!"

"Tony was a great communicator. We were asking for a custom build fence. We had contacted some of the basic fence companies prior to getting Tony’s name and no one would even quote us. He basically helped design in and pulled the permit for us. The end product was great and we’d recommend."

"Katherine, you don't even know and I certainly can’t express how amazing every person of the Callaway Construction Company has been from the first day of receiving the initial call to set up the estimate, the crew, to this message I received from you to finish business. This entire experience has been like no other and that is something to be proud of as an employee of the company and as the owner of the business. I can tell you I'm terrible at getting multiple estimates because as a business owner I believe that if you give me a price for the work requested then that is the price I shall pay for your skill, experience and your word that you are going to follow through and perform exactly as you sold it to me and I can say that Mr Callaway has exceeded in every way my expectations of being a stand up and replicable business owner. I was not present during any of the delivery of materials or construction and I had not one worry in the world because I can tell you every neighbor had given me one update after another and expressed to me everyday how amazing the entire project was going, and I could feel genuine happiness with every word they spoke through messages and phone calls. As I finally arrive in Delaware a week after construction of the new roof I’m met one by one by surrounding neighbors in excitement for me to see the roof and to hear my thoughts. I would give this business a hundred starts and that would times by 10 if the neighbors that contacted me with positive feedback would all leave a review. I highly recommend Callaway Construction for all your construction needs. Katherine is the most amazing person and a true delight to work with. This project consisted of a new roof being built over an existing flat roof. Materials included trusses, metal roofing panels, soffit, siding, etc."

"Atlantic contractors did a great job in building my 14 x 24 three season room. From the beginning, Brent was very responsive to my questions and very easy to work with. He was very patient and flexible going through our community review process. The end product is a solidly built addition that I am very much enjoying. As a note, shortly after construction we had two significant rainfalls and there was no leaks in the windows, doors or roof. I would not hesitate to use them again."

"We had a front and side porch replaced. The entire team worked together effortlessly. They were reliable, competent and preformed high quality workmanship. The work was completed in the time frame given and on budget. Most importantly were the open communications throughout the job. This was huge for me since I was unable to be present for most of the project. Thank you for all your hard work and professionalism. I highly recommend Accessible Home Builders. They were awesome!"

Customers say: Quality work

"I had them build my beach house during Covid and I could not be more pleased with how things went. Materials and labor cost was an issue but I was kept informed the entire way on timing of the items as well as increased cost for the project. They are very quick to respond and also very polite and courteous to me and my wife. I could’ve went with a big builder in the area but would have never gotten the treatment that I did with such a caring local builder. I would highly recommend them to anyone looking for any type of work and the Delaware market."

FAQs for addition to existing structure building service projects in Dagsboro, 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.
