We hired Main Street Design and Build to remodel our primary bathroom. Irakli did a fantastic job, so we hired Main Street Design and Build to remodel our second bathroom. Once again, Irakli did a fantastic job. Professional and kind and always available by text. Both projects finished on time and on budget. We are so pleased we chose Main Street Design and Build to work with us.

OUR DREAM HOME BECAME OUR REALITY Working with Irakli from Mains D&B completely changed what we thought a home remodel could be. Irakli is the G.O.A.T. After an unfortunate experience with a previous contractor where we had to redo everything because it wasn’t up to code, we went into this process cautious and hesitant. Trust had to be rebuilt. From our very first interaction, Irakli stood out. He picked up right away, came to see our home the same day, and took the time to really understand what we had gone through. He walked the space with us and gave a level of clarity and honesty we hadn’t experienced before. We had met with four other GCs, and none of them came close. From that point on, it felt like a true partnership grounded in trust, craftsmanship, and a shared commitment to getting it right. Irakli led the full remodel of our 3,800 sq ft home with precision, care, and a level of consistency that gave us peace of mind throughout the process. We are discerning clients with a strong point of view, and he met us there with patience and a solutions oriented mindset. Whether it was refining design details or accommodating last minute changes, he handled everything thoughtfully while keeping the project on track. What sets him apart is how much ownership he takes. There were multiple moments where he personally stepped in to source materials or resolve issues immediately, just to avoid delays. That level of accountability is rare. Beyond the quality of his work, what truly defines Irakli is his character. He is principled, reliable, and deeply invested in the outcome of his projects. He takes real pride in what he does, and it shows in every detail of the final result. There is a common belief that home renovations are stressful. Our experience was the opposite. It was collaborative, exciting, and genuinely fun. Who can say they had fun during a remodel? With Irakli, we did. We are deeply grateful to have worked with Irakli. If you are looking for a contractor you can trust to deliver, stand behind his work, and truly care about the outcome, he is the one.

Frequently asked questions

How do you handle change orders if I decide to adjust the scope or materials after the remodeling contractor work has already started?
If you want to make changes after work has started—like switching materials or making design adjustments—just let the project manager or your main contact know as soon as possible. We’ll talk through what you want to change and update you on how it affects the schedule and cost. Everything gets written down, so you know what’s new and what you’re paying for. We won’t move forward with changes until you approve them. This helps avoid confusion and keeps your project running as smoothly as possible.
Can a remodeling contractor help me plan a renovation that improves energy efficiency, like better insulation, updated windows, or more efficient lighting?
A remodeling contractor can definitely help you plan a renovation to make your home more energy efficient. This includes suggesting better insulation, recommending updated windows designed to keep heat in or out, and installing efficient lighting like LED fixtures. During the planning phase, they will look at your current setup and talk through the best upgrades for saving energy and lowering utility bills. They also handle the work from start to finish, making sure everything meets current standards and works well together. These updates not only help the environment but can also make your home more comfortable and potentially raise its value.
How do you coordinate your remodeling contractor team of architects, designers, and craftsmen so the project stays on schedule from concept to final walkthrough?
The way the team works together is pretty organized. Everyone—including architects, designers, and craftsmen—communicates regularly, so everyone’s on the same page about the project goals and timeline right from the start. There’s a clear schedule laid out, so each stage (like design, planning, and building) happens in order and without overlap. Project managers keep track of all the details, check in on progress, and handle any problems fast before they slow things down. Updates are shared with the whole team and the client, so expectations are clear and changes can be managed smoothly. This keeps things running efficiently, helps avoid surprises, and makes sure the project stays on track from the initial concept to the final walk-through.
What should I expect during the initial consultation with a remodeling contractor, and how do we get from my ideas to a final design and scope?
During the initial consultation, you'll talk through your ideas and goals for the remodel. The contractor will ask questions about what you want to change, your budget, and your timeline. They’ll take notes and maybe measurements if they visit your space. You can share pictures or inspiration, and you'll discuss how you want the final result to look and function. After gathering details, the contractor explains the design-build process, what you can expect at each step, and answers any questions. From there, they’ll work with their in-house team—like architects and designers—to create a plan and layout based on your input. You’ll review the proposed designs and give feedback. Once you approve the final layout and details, you'll get a clear scope of work, project schedule, and an upfront price before anything starts. This way, your project goals and ideas turn into a detailed plan with a clear budget and timeline before construction gets underway.
Can you help with a phased home renovation plan so I can remodel in stages while staying on schedule and budget?
A phased home renovation plan is a great way to tackle bigger remodels in manageable stages. The process starts with mapping out your overall goals and budget, then breaking the project into smaller sections—like handling the kitchen first, then moving on to the bathrooms, and so on. This approach lets you prioritize the most important areas and spread out costs over time, all while being able to use parts of your home during renovations. Good communication and planning are key, so you’re always on the same page about timelines and expenses before each phase begins. The team can work with you to make a detailed schedule and give clear estimates up front, helping you stick to both the timeline and your budget from start to finish.
Can a remodeling contractor help me choose finishes and materials like tile, flooring, and fixtures to match my style and budget?
A remodeling contractor can definitely help you pick out finishes and materials like tile, flooring, and fixtures that fit your style and budget. With an in-house team that includes designers and craftsmen, they'll walk you through options, show you samples, and talk through what works best for your space and price range. They'll also explain differences in material quality and durability, so you can make the right choice for your needs without overspending. This helps make sure your project matches your vision and stays on budget, with expert guidance along the way.
Do you work with a building contractor on both the design and construction phases for commercial renovations as well as residential remodels?
For both commercial renovations and residential remodels, you can work with the same team throughout the whole project—from the design stage all the way through construction. Everything is handled in-house, so you’ll get help from architects, designers, and builders who actually work together. This makes things easier, since you don’t need to hire separate companies for each phase, and it helps projects stay on schedule and within budget. Working this way also keeps communication clear, so you know what’s happening at every step.
What is your typical payment schedule or deposit amount when I hire you as my remodeling contractor?
We usually ask for a deposit up front before we start work, with the remaining payments split into installments based on project milestones. The deposit amount and payment schedule can vary depending on the size and scope of your remodel, but all the details are clearly outlined in the contract before any work begins. This way, you know exactly what to expect, and the process stays transparent from start to finish. If you have questions about your specific project, we’re always happy to go over the numbers with you.
