"The job is to do pavers and fake grass front and backyard after few months weeds coming on the fake grass and pavers. Vinny landscape said its normal. My neighbor has turf grass but no weeds coming up. I'm holding $500 of payment so they fix it. They the best they can do is to spray the weed and they have to do it every 6 months and I have to pay. The reason I put pavers and fake grass us to avoid the weeds. So the project is useless."

"We hire Geico builders for our kitchen remodeling project, and I'm happy to share my experience: Working with Zaya and Geico Builders was a great decision. They were professional, friendly, and easy to work with. From the start, the process was smooth and efficient. The craftmanship of my remodel kitchen and attention to detail were exceptional, and the end result far exceeded my expectations. From the design phase to completion, their communication was excellent, and I felt completely at ease with them working in my home. The design solutions completely transformed my kitchen, making it both functional and beautiful. I highly recommend Geico Builders for anyone looking for a stress-free and satisfying remodeling experience."

"Oscar truly stands out as a contractor who cares deeply about his clients, and that’s exactly how he made me feel. I reached out to five different contractors to assess my bathroom and offer ideas, but my experiences varied significantly. Some were overly sales-driven, others dismissed my ideas entirely, and one didn’t even follow up with an estimate. Oscar, however, was a breath of fresh air. He arrived on time, listened attentively to my ideas, and offered thoughtful suggestions. He was highly collaborative with the other workers on site, making sure everything was well coordinated. Oscar's expertise in the industry is evident, and he’s exceptionally creative when it comes to problem-solving. When he identified additional challenges during the project, he took the time to offer practical solutions, demonstrating his commitment to delivering the best result. Oscar has earned my trust and will be my go-to contractor for any future projects. I highly recommend him to anyone in need of a reliable, skilled, and dedicated professional"

Second story addition building services FAQs

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.
