"We have had Shirey for two projects. The first was a few years ago when they fixed a roof leak around our fireplace that a couple of other contractors had already tried to fix and had failed. We have had NO leaks since Shirey worked their magic! The second project was just completed this fall. We have three short sets of stairs between our driveway and the front door and I wanted nice-looking metal railings installed on them. Shirey found a customer railing manufacturer and worked with him to make the railings and then installed them for us. I love that it was one-stop-shopping for us. They look great and now I won’t worry about our friends and family falling as they make their way to our front door!"

FAQs for second story addition building service projects in Renton, WA

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.
