"My husband and I have built multiple homes over the years for our growing family. Andy Gruhn was by far the most high quality excellent homebuilder on every level. I truly cannot rave enough or even express my gratitude for the amazing Home They built us!!!! From start to finish, they went way above and beyond, they were quality in details that as a new homebuilder, you donâ t think of until, after the fact, sometimes years, after the fact, I still marvel at the things they thought of for us, that we didnâ t even ask for, that they provided for us to be sure our large family of small children would be taken care of and comfortable for years to come. at the time we were on a very tight budget and they were more than generous. I am beyond grateful to have worked with him and for the quality home they built for our family. They couldâ ve cut corners to save money and make a better profit but instead they just gave us a better home Now that Iâ ve worked with a new builder, Iâ m even more surprised at everything that was included in our home. Heâ s just a standup good community building person that stands by his words and means what he says. When we move back to Washington state Iâ m hoping to build with him again hands-down, I truly canâ t express my gratitude. Andy doesnâ t just build homes he builds communities."

Builder, developer, and general contractor. We succeed through decades of experience, amazing vendor, subcontractor, and client relationships, as well as the extensive resources available to us. From dirt to turn-key, interior to exterior, and bottom up, we are the go-to company for any substantial repairs, upgrades, and builds.

"The project started 10/2021 and ended sometime in 2/2022. This project took long3r than anticipated. I had to check in multiple times to see if anyone would be working on the project that day. The sub contractors used for electrical and plumbing cut corners in places causing issues and failures in 2024. The electrician tapped into existing wires, over loading the breaker and the water tank connections were not threaded and sealed correctly causing a leak with the expansion tank. Luckily I found good people to do the work and get it done right."

We are a small company with4-9 employees. Our focus is on new custom construction, kitchen and bath remodel, additons, concrete stamping and coloring and tiling. License and bonded subcontractors are used in new construction and major re-models. We offer free estimates, and prefer to work with our customers in all design work. We have an excellent line of reasonably priced cabinets and granite counter tops. We are customer oriented and aim to please.

"Jared Lord, owner of Paul Haugen Construction, and his crew are outstanding. They are dependable, honest and do excellent work. Jared's labor and countertop cost for our project was $21, 473,65 (appx. $9K under budget). Our new cabinets, sink, stove top, range hood, tile and garbage disposal were separate costs that we paid for. Regardless, the total cost was below $50K for our beautiful and functional new 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.
