Lo's Contracting, Inc. is your trusted partner for all your remodeling needs in Portland. With over 10 employees, we specialize in kitchen and bathroom renovations. As a licensed contractor in Oregon (CCB Number: 163811) and Washington (License Number: LOSCOCI944BC), we deliver exceptional craftsmanship and attention to detail. Contact us today to transform your home into the space of your dreams.

"We're selling a beautiful home in a historic neighborhood, and our real estate agent suggested we make some repairs and improvements to increase the sale value. I solicited bids from 5 contractors, and Amadou from Lo's Contracting stood out as the right choice from our first meeting. He was friendly and punctual, and worked with us to understand our goals (return on investment during a home sale) and put together a detailed and organized scope of work. The job included a light kitchen remodel (painted cabinets, granite counter top, new fixtures and appliances), light bathroom remodel, interior paint and touch up, exterior siding repairs and touch up, and about a million other little details. His prices were competitive against scrappier, disorganized contractors, and the work started the same week we signed. His crew did a great job, the communication was solid, and he resolved the one problem we had (a bulge in a new marmoleum floor) quickly and without question. I truly can't recommend Amadou and Lo's contracting enough."

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.
