"CHI has done an excellent job for me and I recommend them without hesitation for any remodeling work. Here's why: My job started out with an entry door replacement, evolved into a pantry expansion, and finally finished with an entire kitchen countertop replacement. I was very pleased with how they worked, the materials they used, and the attention to detail in the workmanship. And they were very responsive, communicated well and frequently, and checked in regularly to make sure the job was getting done right and on time. Each of their craftsmen were highly skilled, knew what they were doing, and didn't cut any corners. And each one was friendly and courteous to boot! I very much appreciated their attention to protecting the rest of the house, and they cleaned up the jobsite every single day at the end of their work day. Remodels are disruptive, no matter what. But this was about the least painful I've experienced. I have worked with a lot of contractors. CHI is a 10 out of 10."

"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."

"Would dodge the question when i asked for a contract and never wrote one out, broke 2 of my lighting fixtures (they replaced these), 2 window panes (they replacedone with plexiglass which is plastic and denied the other one), got paint everywhere including my front steps, left a truckload of garbage after saying they'd remove all of it, left asbestos everywhere, destroyed $500 worth of crown molding by cutting it wrong, and left beer bottles that they were drinking on the job in my sink. I'm afraid to have anyone work on my house ever again at this point."

"Ben and his team completed work on my condo and I could not be more pleased with the results. I tasked them with a two bathroom remodels, kitchen sink replacement, and the creation of new sliding doors between my office and the master bedroom. Ben, Marcus, and Pete were prompt, professional, and very considerate of my time and space. Of note is Ben's candor when it came to design ideas, and expense. He advised that several of my ideas weren't worth the money, and suggested more cost effective alternatives, which I really appreciated.

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.
