"Renovating a house is not like renovating 1 room. Weslyn and the workers were responsive and respectful. This was our first big renovation. If I ever have to do it again, I will take more time in the planning phase actually graphically designing each room. We did this for the kitchen and bathrooms and it made the job much easier but it was a lot to get to that point. However, we had to be at the house every day to make sure work kept moving. I couldn't give 5s all around because there were times where we were expecting the subcontractors to do a job but that was not relayed to them properly/or vice versa back to us necessitating extra cost and time to get some parts of the project done. Efficiency was also somewhat lacking and a true Project Manager would greatly help Weslyn's process when it comes to bigger jobs."

"The carpenter that did the job (Adam) was amazing. He had to expand the space for one window, narrow the space for another, and repair much cedar siding that had rotted away due to water damage. He also reshaped my patio door so it would close and lock more easily. He is a very talented carpenter and I have no qualms about highly recommending him."

"i desperately needed gutter cleaning the day before a major storm. I spoke with Dave initially and he worked with me to make it possible and sent out his crew by the afternoon to my house. His crew was so professional and worked very hard to make sure that all the work was done for me and they cleaned up and got rid of all the mess. This company could not have been nicer and helpful. I highly recommend them and am thankful that I found their business."

"Would highly recommend, my house was destroyed by a major fire, and Barbot Construction did an amazing job at rebuilding my home, and now it looks in far better shape than it did prior to the fire. They promised to have the work done in 12 months and finished in 9. I was very satisfied with the work, and they were fair with what the insurance company paid out and the few upgrades I had to pay out of pocket. They were very detailed with the insurance estimate and worked well with our insurance company."

Subcontractors FAQs, answered by experts

It can take anywhere from a few days to several months to draw up architectural plans, depending on the complexity of your project. Architectural plans are highly detailed documents that take time to complete, and any changes or alterations can significantly extend how long they take.

If your project is complex, it may make sense to hire an architect to draw plans. An architect might also be a good person to hire if you want to ensure your plans adhere to building codes and regulations.

Builder-grade is one of two types of stock cabinets, whereas semi-custom designs allow homeowners some control over the color, finish, or hardware on their cabinets. Stock cabinets are sold in construction-grade and builder-grade designs. Construction-grade cabinets are usually made from inexpensive medium-density fiberboard, which is prone to moisture damage, whereas builder-grade models are a step up with higher-quality materials. Construction-grade designs are the most common type of cabinets in America.

Costs vary depending on project complexity and scope. Architects generally charge a percentage of the total budget or an hourly rate for their services.
