"My family and I hired Jeff as our General Contractor to oversee the construction of our 1500 sq. ft. summer home. It was the best decision we made regarding this project. Jeff was a pleasure to work with. He was attentive to our design requests and of our vision for this home, while providing his expertise in all phases of construction from site work, foundation, framing, siding and roofing, stairs, and all interior finished work – including installing wood molding trim, doors, closets shelves, kitchen cabinets, bathroom vanities, all of which he does himself. Jeff hired and coordinated reputable subcontractors required to complete the project on schedule, and met all of his commitments regarding price, quality of materials, and high standard of professionalism and quality construction. Jeff was responsive over the 6-month schedule, keeping us informed of the overall progress, including subcontractor and weather delays, local permitting challenges, and coordination of several building inspections – all of which passed the first time attesting to the quality of Jeff’s work. Overall, whether it is a large or a small project, we wholeheartedly recommend Jeff for your construction project."

"We had this company build a new master-suite in our home. That included floor plan changes, tiling the bath, installing a new shower, a jetted tub and a new toilet. Only 3 months after many things fall apart. A glass shelf almost fell in the tub when my wife was in it. It almost injured her. Towel racks came of the walls leaving giant holes behind. The brand new tub stoped draining. I brought in a licensed plumber to fix that and he told me he never saw "such a sh*tshow".

"I contracted Black Stallion Enterprises LLC to replace the roofs on two of my houses. The entire process from the initial estimate to completion was fair, easy, transparent, and professional. They arrived promptly, completed the job on time and within budget. The workers were clean and worked full days with minimal disturbances to our everyday activities. Joe oversaw the job and provided step-by-step updates, explaining what was being done and the reasoning behind it. Additionally, where things were not done properly by the original builder, BSE added the necessary products and fixed it, all within the original price estimate. The roofs look beautiful, and we are already seeing efficiency as a result of the replacement. The BSE team followed up after completion to ensure we were happy. They definitely stand behind their work and materials. I highly recommend BSE for all construction projects and will hire them again."

FAQs for water heater installation and replacement projects in East Dennis, MA
You'll need an expansion tank if your home has a closed water system, which is standard in newer homes or those with backflow preventers or pressure regulators. Expanding hot water has nowhere to go in closed systems, creating potentially damaging pressure. The expansion tank provides space for this expanded water, protecting your plumbing system and water heater from premature failure. Many local building codes now require expansion tanks, and some water heater warranties may be voided without one.
For a standard 50-gallon water heater, a two-gallon expansion tank is sufficient. This sizing assumes normal household water pressure between 40 and 60 psi. If your home has higher water pressure (60 to 80 psi), consider upgrading to a slightly larger tank for added protection. The expansion tank's purpose is to accommodate the increased volume that occurs when cold water heats up, which is proportional to your water heater's capacity.
Watch for signs like dripping water around the tank, fluctuating water pressure throughout your home, or unusual noises in your plumbing system. A properly functioning expansion tank should feel light when tapped on the bottom—if it feels heavy or waterlogged, the internal bladder has likely failed. Other indicators include frequent triggering of your temperature and pressure relief valve, visible corrosion on the tank, or unexplained increases in your water bill, suggesting hidden leaks.
Most expansion tanks have a service life of five to 10 years, though some may last up to 12 years or more with proper maintenance. Factors affecting lifespan include water quality, system pressure, installation quality, and tank construction. Hard water areas often see shorter lifespans due to mineral buildup. Regular maintenance checks can help identify potential issues before complete failure. When your water heater is due for replacement, it's wise to replace the expansion tank simultaneously, even if it hasn't failed yet.
A 30-gallon water heater needs an expansion tank if your home has a closed plumbing system. The need for an expansion tank is determined by your plumbing system type rather than water heater size. Even smaller water heaters create thermal expansion when heating water. If your home has a backflow preventer, pressure regulator, or check valve on the main water line, you have a closed system that requires an expansion tank. Check your local plumbing codes, as many jurisdictions now mandate expansion tanks regardless of water heater size.
