We're a small plumbing company with myself and 2 other employees. We don't subcontract much, asphalt and street replacement mainly. We are typically pay at time service rendered. For corporations and title companies, we will wait 30 days if necessary.

"Very responsive! I called Matt on a Saturday afternoon, and he replaced the garbage disposal the next day. Very reasonable price. The cost included the price of the new garbage disposal. Highly recommended!"

FAQs for second story addition building service projects in Saint Charles, MO

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.
