"Awesome company! Called on Friday and they came out first thing Saturday morning. Another company supposedly tried to snake the drain then told me the drain couldn't be unclogged and the basement floor had to be dug up to get to the main pipe to replace it- $5,000- $7,000!! Along came AllClear and said there was no way the drain could have been snaked without cutting the pipe as it was a double sink- so he cut the pipe and found the clog in the trap- snaked the main pipe where there were no problems and now the water runs right on through. So happy - will definitely call again for any future needs!! Also referred to friends and family!"

FAQs for second story addition building service projects in Hamilton Township, NJ

For many homeowners, building up is worth the expense because it provides the extra bedrooms or living areas that can’t be accommodated within the existing footprint. A larger, updated home often commands a higher resale price, recouping a sizable share of the project cost while allowing you to stay in the neighborhood you love. Run the numbers with a real estate agent and contractor to ensure the expected return and day-to-day benefits align with your goals.

Whether it makes more sense to build up or out depends on your lot, budget, and local code. Building up preserves yard space and involves less foundation work, but you may need to vacate the home during construction. Building out avoids staircases and can proceed while you stay put; however, it encroaches on the yard and may face setback limits. Compare both options with your contractor before making a decision.

A structural engineer will first inspect the existing foundation for cracks, footings, and load capacity. Depending on the findings, the crew may pour new concrete footings, install steel or concrete piers, add reinforced beams, or tie additional rebar into the slab. These upgrades redistribute the weight of the new floor and bring the structure up to code. Your contractor will outline the specific reinforcement plan and timeline once the engineering report is complete.
