Unlimited Outdoor Designs, specializing in Indoor Kitchens and Baths and Basement remodels. Fencing, Decks, Railings, Concrete, and Masonry work. We are family-owned and take pride in treating our clients like family. We've built an excellent reputation for customer satisfaction by providing quick estimates, a great attention to detail, and competitive pricing.

"We had three companies call us back. Company 1 met with us to discuss our wishes and drew a rough sketch of the proposed work. They said they would work up a more detailed drawing and e-mail it to us for review. A few days later the sales rep sent a text asking if we had a chance to look at his proposal. I said we never received the drawing and perhaps it was sent to the wrong e-mail address. I confirmed my e-mail address and was told that he would correct and resend. I never heard back from them. Company 2 met with us to discuss our wishes. We ended the meeting with the expectation that they would send me a formal proposal. I never heard from them at all so they were even less responsive than Company 1. Fortunately Universal Unlimited called us also. Universal Unlimited (Hector Marmol the owner) wasn't the first to respond to our project request but his was the most responsive. We set up a meeting. Hector Marmol (the owner) listened to our wants and used his PC to create a rendering of the proposed deck based on our talking points. We also inquired about PVC fencing for a future date. Hector gave us a very attractive price for a bundled package of decking and fencing. We accepted although I was a little hesitant because most of his reviews were for fencing. I'm glad we made the decision since the final results were exceptional. Props to Jose Salguero who did most of the work."

FAQs for second story addition building service projects in Valley Stream, NY

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.
