"Didn't even get to the job. Called 02/22/23 to schedule quote. Scheduled it 8 days out for 03/02/23 for 11:00. Called at 10:55 to inform his engineer went to the wrong address but both should be there shortly. At 11:09 texted to inform me no one was at my house and we needed to reschedule, despite me standing at the window waiting. After 30 minutes and several texts, confirmed he went to wrong address but too busy and needed to reschedule. Not very professional and very little respect for possible client."

FAQs for second story addition building service projects in Boulder, CO

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.
