With several years experience, we work hard to bring each customer the best possible service and quality available. We look forward to working with you on your next project. We welcome your questions and thank you for your interest.

"I can't say enough good things about Justin and Affinity Construction! Our project went from a wood frame RV carport 20x45 to an enclosed garage. Justin came out several times as we worked through the build plan. Affinity was covering all the bases from foundation to paint color. Justin is great to work with and goes the extra mile to ensure the customer gets what they want. Unfortunately, the city had easement issues on the build site and wouldn't allow a structure to be built. We had no other suitable location for the garage, so the project was scrapped. This is when I decided Affinity Construction would always have my business. Justin returned my deposit, and went further introducing me to other professionals he trusts to bid on the smaller side projects we were going to do while the garage was being built. The true measure of a quality company is how they react when things turn sideways and how they treat their customers when money is no longer changing hands. 10 stars!!"

"Excellent! Joe was referred to us by a professional colleague. The bottom step of our deck stairs had a lot of give. Joe inspected and showed us how the entire bottom of the stair structure had water damage and rot due to improper original build. An interim fix by another contractor had been wholly insufficient — it had only been superficial. Joe and crew fit us in and met our tight deadline for our son's graduation party and replaced the entire staircase in just two days. It was done timely and expertly. Especially appreciated were the before and after photos, as well as the detailed description of the problem, the associated safety issues, and the fix. He was also able to re-use the Trex planks — only needing to replace the rotted structural boards. The new staircase is solid! We'll now have Joe bid on a much larger project for another property. He's our new go-to guy!"

"Look no further! Our kitchen remodel was top to bottom and even included tear-out of ceiling soffits. From the start: Pricing was competitive with an easy to understand estimate. Classic or trendy, Kristeen teaches at a local college and knows what’s out there and what we could expect. Communication was easy and prompt. Everyone was GREAT to work with and the job was completed ON TIME. They go ABOVE & BEYOND! Over a year after we were done our “Smart” faucet motor went out. At no charge, father and son came out and switched it out for us. We have done our share of remodeling and wish we had found them sooner. I LOVE my kitchen!"

Addition to existing structure building services FAQs

How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.

Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
