Common Process Questions
-
Free estimate visit: We meet on-site at no cost to understand your goals, scope, and timeline.
Feasibility range: After the visit, we provide a realistic budget range for free so you can decide if the project is in the right neighborhood before going deeper.
Next step (design + detailed quote): If you’re comfortable with the feasibility range, we move into design + scope development (with a design fee that varies by project). Once the design/scope is defined, we deliver a detailed quote based on those specifics.

We love helping you design your project and select materials that match your style and budget.
We do require a design fee for all projects ($500 - $7,500 typically. $4,250 on average, dependent on project scope).
Once the designs are complete, they’re yours to keep and use however you’d like—whether you build with us, someone else, or decide to pause. If you already have architectural plans, we’re happy to work from them and won’t ask you to start over.
“They had to try to match our tile and they did an awesome job. The new tile brings out pops of color in the bathroom My wife and I love it. - Wayne D., Bathroom Remodel
-
Ranges are created from the measurements, notes, and goals discussed during your estimate visit, then run through an AI pricing model our team trained and refined specifically for feasibility analysis using real project history and current industry pricing.
That allows us to give you a more informed early range than a rough guess- all before any design fees.
If the feasibility range feels right, the next step is design, where we refine everything into a more exact quote based on finalized scope and selections.
-
Cost changes can happen in remodeling when existing conditions are uncovered after work begins, such as hidden damage, outdated wiring or plumbing, or structural issues behind walls.
Changes can also come from scope adjustments, material selections, or design decisions that evolve as the project is finalized.
Because of that, we recommend planning for a 10% safety buffer above the design quote to help cover unexpected costs if they come up. It is simply a smart safety net we make clients aware of early, so there are fewer surprises later.
-
1-year workmanship warranty on all work performed by ISI Construction and our trade partners.
Covers defects in workmanship.
Does not cover damage caused by vandalism, homeowner neglect, or theft.
Many products include manufacturer warranties (varies by item).
If a material defect arises, we can help coordinate with the manufacturer toward a resolution.
We do walkthroughs throughout the project and again at final completion to note touch-ups/punch items and address them so you can enjoy the finished space with confidence.
“We had a couple of warranty issues that they were right on top of. Extremely satisfied with the whole remodel.”
- Ralph B., Whole-Home Remodel
“They were very informative, qualified contractors, personable yet professional. Very easy to work with.”
-Denise B., Kitchen Remodel

Our Story
Frustrated with the lack of transparency and quality while working for large production builders, Joe and Tyler felt unable to enact the changes their Christian values demanded.
In April 2022, they took a leap of faith and founded ISI Construction.
Our mission is to bring integrity, honesty, transparency, and exceptional craftsmanship to your home remodel project.
“Homeowners Deserve Better.”
“Too often, in our previous roles, we saw clients being taken advantage of by contractors who cut corners or prioritized profits over quality. We knew that homeowners deserved better.
That's why ISI Construction exists – to protect clients from bad practices and deliver the remodeling experience you deserve. We are committed to providing high-quality services at a fair price, without ever sacrificing our morals or values.”
“Blessed to know these guys.
