A Clear Process From First Call to Final Walkthrough

Here is the real world flow most clients experience:

Define

01
Bright modern kitchen with light cabinetry, gold hardware, a clean island workspace and warm natural light styled by ISM Construction.

Discovery Call

We have an initial phone call to determine if we are a good fit for each other. We will talk about the location, scope, budget, timing, etc.

Initial Meeting

At our in-person meeting to get to know each other and about the project. We start talking specifics about what a customer's wants and needs are and develop a rough plan.

Ballpark Review Meeting

Based on our meeting we will create a general scope, price, and then meet to review everything with you.

Design And Site Agreements

After the review meeting a design agreement is presented to develop detailed plans. A site engineering agreement is presented to get a head start working on any required site engineering needs while we finalize plans and specifications.

Refine

02
Contemporary kitchen with a dark island base, warm brass lighting, clean cabinetry lines and a bright window view styled by ISM Construction.

Detailed Prints

After a signed design agreement we will create plans for the project. This will include a full set of plans and 3D renderings.

Detailed Specifications

Once we have a plan we will create a detailed specification sheet and price based on the plans.

Meeting To Review

In this review meeting we will pull up the plans and 3D model for the customer to visualize. We can make changes to the plans and model in real time. Also during this meeting we will review all the specifications to make sure everything is captured.

Site Meeting

We will then set up a site meeting. For new homes it is to see how the house will fit on the land and how the grade will work around it. For remodels & additions it is to confirm measurements and verify how all of the mechanicals will connect.

Plan & Spec Updates

We will make updates based on the site meeting information and customer's wants/needs as many times as it takes until the customer is happy.

Contract

Only once site engineering is complete and the customer is happy with the plans, specs, & price will we present a contract for a customer to sign.

Build & Deliver

03

Selection Meeting

This is when we will choose all the finishes for the project. Our design studio and 3D renderings help you visualize your selections in real time. There is a lot to pick out so we typically break it up into several different meetings.

Groundbreaking

We kick off construction with a groundbreaking meeting to walk through the project scope, timeline, and key milestones with you.

Mechanical Walkthrough

During construction, we conduct a mechanical walkthrough to review all systems, rough-ins, and structural elements before they are covered up.

Final Walkthrough

Before you move in, we complete a final walkthrough to ensure every detail meets our quality standards and your expectations.

Scheduled milestones & Clear Communication

We keep you informed throughout construction with structured milestones, scheduled walkthroughs, and regular communication. Payments are tied to progress at key milestones so you always understand what you are paying for and why. We review the full schedule with you before construction begins so there are no surprises.

We cannot recommend ISM enough. Every single person in the company has been amazing to work with. They were very responsive and at times during the planning phase when my husband and I did not see eye to eye, they came up with designs that combined what my husband and I wanted, that we are both happy with. They have been extremely accommodating as well with last-min changes. And they work with (most) contractors that very much care about what they do, that resulted in high quality workmanship. We highly recommend working with ISM for all of your project needs.

Building our forever home was something I had dreamed about for many years. The moment we met the team at ISM Construction, we felt at ease and reassured that we were in good hands. We knew they would be the right company to build our forever home. Their knowledge, experience, and reassurance helped us decide that ISM was the builder best suited for us ISM operates with integrity, responsibility, and a strong sense of accountability, and that spirit shows in everything they do. Ivan carries himself with a calm confidence that immediately puts you at ease. Josiah led our project and shared their program with us, which included a construction schedule, changes made, our selections, and many other details that made everything easy to follow. His steady leadership, great patience, and willingness to explain things more than once were truly appreciated. Nate was incredibly detail-oriented and organized. Many of the thoughtful ideas in our drawings came from his careful planning. Dawson, our project manager, was hands-on, personable, and always kind. When we visited the site, he answered all our questions with confidence and honesty. Together, they truly make an exceptional team. There were quite a few decisions to make, like layouts, finishes, details I didn’t even know existed. Permit requirements were also an important part of moving forward which ISM handled effortlessly. They walked us through each step and remained committed to the schedule, even through last year's rainstorms and mud. Watching our land transform into a home was amazing and something I will never forget! As with any large project, small adjustments along the way are simply part of the process. What mattered to us was that the ISM team approached everything with professionalism and a willingness to make things right. That gave us peace of mind. ISM didn’t just build what we imagined, they helped make it even better. Now that we are settled in, friends and neighbors often compliment the beauty and quality of our home. It is everything we hoped for and more. We feel truly blessed to have worked with this team, and we are so grateful for the care they put into building our forever home. I would wholeheartedly recommend ISM to anyone looking to build. They will treat you like family and take pride in doing things the right way.

Designing and refining a set of plans and bringing them to life requires the right partner and we were blessed to have found and work with ISM. A selection process that was detailed, an organized schedule so we knew what was happening and when, communication throughout the project and working through challenges when things didn't go exactly as we planned made for a successful project. We couldn't have envisioned the final product when staring at an untamed wooded lot on stake out day. But ISM's experience, their excavator's vision (shoutout to Jere of On-Track!) made for a remarkable home we are lucky to have. Thank you Ivan, Josiah, Nate, Dawson and the whole ISM team!

We did a remodel and an addition to our house and ISM were the best. Total professionals and everything exceeded our expectations. They gave us a schedule for 4 months and everything was done on time or earlier. They are perfectionists and it shows in the quality of their work. We need to remodel our kitchen and bathrooms next and there is only one company we will use and it’s ISM. Thanks so much for everything.
