Our services are customized to your individual needs, paying close attention to the details of each project that we are involved with. Please feel free to contact us today!

"I can't say enough good things about my experience with Randy Preston and his crew!! Randy helped me renovate a garage that was in SEVERE disrepair into a beautiful and charming studio cottage. The craftsmanship was excellent. I regularly get compliments and feedback that the cottage has the feel of a home that's been there forever (think circa 1940's cottage). The crew was always on time, kept the site neat and clean and were super easy & pleasant to work with. Randy's personality is "steady and calm" - nothing ever felt like a problem - if it was within his power, he handled it and if it wasn't, he helped me figure out next steps. Renovations are rarely stress-free but Randy's nature helped to make it as stress-free as possible. I think the thing I was most impressed with was his transparency and honesty. He was the only contractor that provided me with a fully itemized estimate. I knew exactly how much was budgeted for EVERYTHING and at the end of the construction, he actually credited me back money for things I would have NEVER known cost less then estimated. Every step of the process (that he had control of) was great. I'd hire him again in a heartbeat and hope I do get to use him again for a future project I have in mind. If I haven't gotten the point across yet, I highly highly recommend!!"

After 20 years of spending summer and winter vacations at our family home in Rehoboth Beach, we made the move in August of 2019 and enrolled our daughter in Rehoboth Elementary School as well. While we are new to the area as full time residents, we have a long family history in Delaware. Lamb Residential Services primary focus is older homes. With 2 decades experience, we can manage large renovations and restorations, as well as maintenance and the small tasks of historic homes. Additionally, we carry the required General Contractor's Licenses for Rehoboth Beach, Henlopen Acres and North Shores.

"We had an absolutely outstanding experience with Michael and his crew! Michael was very creative in helping us envision the projectâ adding a second story to our ranch houseâ in ways we had not thought of. He understood and adhered to our budget. *Impeccable* work down to the last detail. Excellent project management â everything ran like clockwork. Great communication as wellâ we were never left in the dark about a detail or left wondering about progress, even though we were an hour and a half away. Crew was excellent as well! And the finished product is better than we dreamed of. We recommend him wholeheartedly!"

"I was noticing cracks in the ceiling and baseboards. I had Eagle Eye come and check my trailer to see if it was level. It was off 1/2 inch and they fixed it the same day. While they were under the trailer they noticed one of my heating vents had a huge crack in it. They took pictures and a video to show me. It was the weekend with very low temperatures. They came the next day, which was a Saturday, freezing and windy, they did the job for me because they didn’t want me being cold. I had a critter underneath and they checked around my house and found two holes that went underneath the crawl space. Covered the holes and no more critter. In my opinion, Eagle Eye construction is worth there weight in gold. "

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