"We needed to have a walk-in-shower installed to replace our 20 inch high whirlpool bathtub. Through Angie’s List we found the perfect contractor in Calloway Corporation LLC. The owner Keith stopped by within a day of posting, looked at our layout and what we wanted done and he was back a day later with the estimate which was very reasonable for the work we wanted accomplished. We had to revise the original estimate a few times only because my wife wanted extras added which was not a problem. The owner and his right-hand manager Katherine were more than agreeable and cordial in meeting our needs and goals. The work crew was very punctual showing up every day at 0700, military time, 7:00 am. Retired Navy, what can I say. The demolition phase included R J and Jeremy removing the old walk-in shower and attached closet, removal of the huge whirlpool tub and the large Glass Block Window. Removal of the window necessitated cutting a hole in the siding, removing the old insulation and boards. Luckily, we had two boxes of new siding in our attic for the initial house build which saved us money along with floor tiles that were used to patch and enlarge the floor. Once the backdrop for the new shower was installed with the necessary braces for tie in of the grab bar and teak chair that same day the two carpenters installed new insulation and siding. And honestly it looked as if it was the original work. The carpenters were outstanding. Very meticulous, paid attention to detail, and did not miss one nail on outside clean up. Masters of their Trade!!!! What really impressed us was the way they treated our home with respect putting drop cloths on all the floors leading to the bathroom work area. They also did a top to bottom clean up at the end of each day’s work. The tile setter Rob is a Master of his trade. Probably one of the best tile setters in Delaware. Talk about perfection!!!! His final work looks good enough to be a multi-million-dollar mansion. Our walk in shower looks fabulous. Keith and Katherine provided us with the best sub-contractors in the area. The Plumber, Electricians, and Painters did a fantastic job and cleaned up afterward and took all waste products with them. Not only did R J and Jeremy work on demolition they also built beautiful, sturdy and space saving shelves and put on perfectly closing folding doors, installed new tiles and installed the grab bar and teak seat in the shower and installed our new vanity with all the hardware. Everything came out Beautiful. My wife and I both love what they accomplished for us. I know this was verbose but I wanted to instill in anyone who needs a top-notch contractor and crew who complete a project with pride in workmanship, work ethic and trustworthiness to call on Calloway Corporation for any project. I close with “BRAVO ZULU!! “A U S Navy term for Job Extremely Well Done!! Thank you all for your kindness, efforts and patience. J J & Mona"

"Pete arrived before his crew to look over the job. The crew arrived on time and started work promptly. The roof was finished a bit after noon and the job site was cleaned up. From start to finish they did an excellent job."

"I am a senior with a background in construction.  After reviewing many contractors and speaking with some of them, I immediately knew I hit the jackpot when I spoke to Danny.
 
1.  He knew exactly what I needed and wanted done when I first spoke to him.  This entailed the replacement, repair, and installation of the items listed above with attention to quality in materials, prevention of future problems, a fair price, and a commitment to starting and showing up once the job was initiated.  Danny exceeded every expectation in these regards!
2.  I silently knew in advance manufacturers, quality and cost of exterior doors (including the french door), storm doors, door locks and deadbolts, leak-proof door sills for 6 inch exterior walls and a leak-proof barrier on the bottom of the door frames.  Without knowing of my preferences, Danny suggested the identical manufacturers and materials I had in mind.  At this juncture, we met and I hired Danny to perform the work.
3.  I am beyond pleased with the outcome of Danny's effort on this project.  As an example of his integrity, he asked me to trust him in the design and installation of an exterior octagonal window in a bathroom.  My wife and I were literally blown away with a handcrafted symmetrical waterproof tunnel and inside wall frame he created - more akin to an artistic piece than a window.
4. Inside work was always minimally invasive using tarps and soft shoes rather than work boots.  Outside and inside cleanup at the end of each work day was respectfully performed leaving no mess.
I would recommend Danny to anyone requiring any kind of interior or exterior installation, modification, or repair as I have seen firsthand examples of his experience, skills, and personal and business ethics.  In fact, Danny is presently working on costs to replace our roof."

"Exceptional work by the team at M.R. Hunter. Old cedar siding removed, new PVC siding installed. The new siding retained the look of the original wood with the advantages of a maintenance free material. The MR Hunter team was professional, listened to any concerns, maintained a clean work site, showed up and worked full days. We are enjoying the new siding and highly recommend MR Hunter."

"THEY WERE GREAT! I HAD CALLED ANOTHER COMPANY WHO DECIDED TO DO THE HIGH PRESSURE STUFF AND REFUSED TO GIVE ME AN ESTIMATE UNLESS I BOUGHT TODAY.
DAN FROM GUTTER PROS CAME OUT MEASURED IT UP AND LET ME KNOW I COULD TAKE AS LONG AS I NEEDED TO MAKE A DECISION. THEIR PRODUCT WAS GREAT TOO. I EXPLAINED I WANTED TO CHECK THEM OUT AND READ REVIEWS ON THEM AND THE PRODUCT. SO I TOOK A FEW DAYS AND GOT BACK TO THEM. 
LOVED THE INSTALLER, WILL, ALSO.
I HIGHLY RECOMMEND TO ANYONE LOOKING FOR A GREAT PRODUCT AT A GREAT PRICE.
WE HAVE HAD PINE NEEDLES CLOGGING THE GUTTERS FOR YEARS, I WAS JUST FED UP.
SO, I AM EXCITED TO HAVE THIS DONE.
THE OTHER COMPANY THAT WAS OUT WAS LEAF FILTER OR GUTTER HELMET, I DONT REMEMBER. THE GUY WAS NICE ENOUGH BUT WAS GETTING MAD WHEN I TOLD HIM THAT I NEEDED TO DO RESEARCH.
SAVE YOURSELF SOME TIME AND CALL THESE GUYS.

"Excellent work, service, price!! All Exteriors was 1 of 5 companies I contacted for a quote. Bill came and walked roof, explained material options, addressed all my concerns with various leakpoints I’d discovered upon moving into my home. He communicated promptly regarding scheduling, his crew was great, they worked efficiently to complete my roof same day. They cleaned up all the materials upon completion and showed me at different points how they addressed the pre-existing damage/leaks. I will definitely use All Exteriors again. In fact, planning to hire for exterior wall of home that also has extensive water damage (from roof problem). Unfortunate to have this going on with newly purchased home but having a reliable, competent contractor makes a huge difference."

FAQs for flat, foam, or single ply roofing installation and replacement projects in Nassau, DE

Many roofing pros point to PVC as the top performer on flat roofs thanks to its tough seams and long-term waterproofing. A properly installed PVC membrane can last 30 years or more, resisting ponding water and harsh weather with ease. You will pay more up front than you would for EPDM, but the added durability often translates into fewer repairs and a lower cost per year of service.

Yes, a rubber roof is an environmentally friendly choice. Most rubber membranes contain recycled content and can reflect heat, which helps trim cooling bills in hot weather. Manufacturing has a lighter footprint than many traditional materials, and the long lifespan means fewer tear-offs headed to the landfill. If sustainability is a priority, ask your roofer about brands that carry third-party eco-certifications and confirm they meet local environmental standards.
