At LP Customs, we build custom homes, log homes, major remodels like addtions, basements, bath and kitchen remodels. Since we are a smaller business, we are able to provide our clients with a more affordable price. We do all phases of construction. Clients really like the idea of one crew in their homes versus many subcontractors. We can provide many references to prove that our quality speaks for itself. Give us a chance to bid your next project, you will be glad you did. Please call us at 1-608-575-8338. You can also review our work on LP Customs, llc facebook page! Check out the album section.

"The final product is good and the price was good. The structure all seems to be high quality and with double pane windows it can hold the climate or out well as needed. With screens all around we can let the air move through when we want. The design process was a good experience, but we were not warned that our decisions in dimensions would result in difficulties with regulations and the electrical work. The lack of communication between sub-contractors during the process resulted in several delays. There were times when we were told there would be hand-off and it didn't happen until we prodded them. We kicked it off in the early spring and it didn't complete until August. Early on, the delays were unavoidable due to weather and ground conditions but after the foundation was in it took to long to complete the structure. The problem is not specifically the total time to complete but being left with very little time to replace the yard and driveway before winter."

"When Mike came out to give me a quote, he told and told me he would get back to me in a week and could probably finish part of the work in the next two weeks and start the full remodel within a month. That was in January, and I'm writing this review at the end of March. I called him several times and finally caught up with him about a month ago, when he said he had had some family issues and would get back to me soon. But he never did. I spent time cleaning my house, speaking with him, writing him an email with all the details of my project, calling references, and waiting months for an answer. The very least he could have done was said he wasn't interested in the project."

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.
