OUR PROCESS, OUR SYSTEM
Kirkham Building System, Inc. is just that, a system that works for you from beginning to end. From initial contact to building completion and warranty, the way we do things keeps focus on giving you the best product at a fair price.
We want to briefly describe what to expect at each step:
-
However you found us, we're glad you did! We appreciate the opportunity to share our story and expertise with you and look forward to helping you plan your new project. Simply call, email, or submit on our website for a free consultation. We'll set up a time to get together at your site and start planning.
-
KBSI takes a collaborative, consultative approach to design — their experienced planners work closely with clients to understand the full scope of their needs, asking the right questions to ensure the building is sized, configured, and equipped perfectly for its intended use. This in-depth planning process applies to all project types, from personal storage and farm buildings to commercial spaces and churches, eliminating the need for a separate architect on most projects. To get a head start, clients can download KBSI's preliminary floor plan and begin thinking through the many versatile options available for their post frame build.
-
Once an agreement is signed, KBSI handles engineered drawings and permit submissions, while the client is responsible for zoning permits and any other locally required approvals — with construction scheduled as soon as all permits are in place. Site work is coordinated as the first step, and clients who handle their own site prep should plan to have it completed at least two weeks before construction begins. From there, KBSI manages all contracted construction from start to finish, keeping clients informed throughout while delivering professional, high-quality workmanship.
-
KBSI takes pricing seriously by providing accurate, detailed proposals that account for all costs — including materials, labor (calculated to 1/10 of a minute per piece), taxes, and insurance — rather than relying on vague ballpark or per-square-foot estimates. Each written proposal includes a scaled floor plan, transparent terms, total project cost, payment schedule, and warranty details, all presented in clear, straightforward language. Proposals are typically valid for 30 days, and KBSI always reviews them with the client to ensure everything is accurate and meets their needs.
-
Upon project completion, your KBSI planner will walk through the building with you to review features and door operation, at which point final payment is typically due. KBSI backs their work with a 5-year material and workmanship warranty, and additional manufacturer warranties may apply to specific products like roofing, siding, or overhead doors. With over 34 years in the Delaware, OH area, KBSI has the established presence and commitment to ensure they'll be there for any warranty needs that may arise.
