I hired Excel Construction LA to a full interior remodel of a 1928 home that I purchased as a rental property, but quickly determined I had underestimated the amount of work and investment required to get it rental ready. As a casual landlord, I did not have much experience with remodeling, managing contractors, estimating costs, etc. But I loved the house and had a vision for what I wanted to create. I chose Excel Construction LA because I felt they understood my vision and would be flexible along the way. I was right and they proved to be a fantastic partner. Excel was always able to provide quality materials at a reasonable price, they were extremely flexible and accommodating working with my schedule and they produced quality work. The managed the entire permit process and went above and beyond to ensure all inspections were passed - not just the city's inspections, but also the buyer's inspectors. In the end, we turned a very run down home in South LA into a beautiful new home that sold for the top price point in the zip code - something local realtors said could not be done. Excel deserves a ton of credit for this. Nofar, Evan and the entire Excel team were super helpful and fun to work with, as was the sub, Jorge. Thanks Excel!

We decided to install a hot tub in the backyard but needed a 220 connection away from the house. We tried to do some of the work ourselves by prepping an 18" trench for an electrician to come and wire. The soil was tough and the job harder than we thought. American Castles came and picked up where we left off, dug the remaining trench, connected the line, installed the box, and even recessed some of the line behind the stucco for a better visual. They didn't cut corners, showed up in a big team, and took care of everything without a problem. Price was reasonable. I would hire again.

Jay is amazing!!! He came to check out my project and we booked him for the following week. The clients made some last minute changes but he was willing to work an extra day to make sure we finished our deadline. He has a great personality, very knowledgeable, and goes above and beyond. We will definitely be using him again, thank you Jay!

We got quotes from a few landscapers and were impressed by DG Construction. We had a vision for our backyard and they did an excellent job in making it happen. They were here at the times they indicated and they finished the job well within the time frame. We are more than pleased with our new backyard and so are our visitors. Would definitely recommend. David of DG Construction is more than willing to do what it takes to please his customer and is willing to listen to suggestions and ideas.

I have worked with many contractors on various home and office projects. This was my first time building out a retail store on a tight budget, with champagne taste. Brad & David turned out to be the ideal contractors for the job. These guys don’t just build what we agreed upon, they made me aware of all my choices beforehand and helped guide me to all the right design decisions. And even their crews of builders and painters were exceptional craftsmen. Brad & David brought my project in exactly on budget and before the deadlines. They are real pros and every question and request from me was promptly responded to. I will happily work with them again and feel lucky to have found them.

Mana Design Build just finished remodeling all 3 of our bathrooms. We love them and our new bathrooms. Our master bath was a complete mess and needed everything from new fixtures to new placement of shower, sink and toilet! Mazi (the owner) and Angela (the designer) was so knowledgeable of the latest designs, fixtures and really listened to what I wanted in my bathroom. Based on my input, she brought out fabrics, tile, granite samples all to my home. I didn't need to do any of the running around! She and Mazi met with us every step of the way! Demolition took only one day! He then reconfigured all the electrical and plumbing and started building my bathroom from scratch. The end result is a super functional, up-to-date master bathroom! Mazi then conquered our other 2 bathrooms. They needed a facelift: new tile, vanities, toilets, paint, the works! One of the benefits of working with Mana Design is that they are a design and build company. They provided all the materials, made all the necessary appointments for permits with the city of Lake Forest, and cleaned up the "remodel" mess every day before leaving! I am super pleased with my bathrooms! The work is clean and meticulous, and I know if we ever had an issue with something they would be out immediately to fix it. We look forward to our next project (remodel kitchen) with Mana Design Build!

Scott and Victor were great to work with. We hired them to replace our first floor tile, baseboards, and paint half the interior walls. They also fixed an unexpected water leak during the tile project. Towards the end of the tile project, we decided to have them replace our patio deck and build a vegetable garden box. They were responsive, polite, showed up everyday, addressed every question and request we had. We will definitely hire them again for future projects, since they pretty much do everything.

Working with Ray was great, he was very professional and courteous. He took the time to understand what we needed and wanted in building a new master bedroom with a full bath plus and extra 1/4 bath and laundry space. Ray produced very detailed plans and met with the city 3 to 4 times in order to satisfy their requirements. He always arrived on time, to our appointed meeting times. We found that the pricing that Ray charged was very reasonable. He was not the lease expensive quoted through Thumtack, but we feel it definitely was the best value. I would highly recommend Ray to my family and friends who may need architectural services.

Q & A

Answers to commonly asked questions from the experts on Thumbtack.

What is a general contractor?

When starting a home remodel or new construction project, you will probably hire a general contractor. A general contractor is a professional who is qualified to take a set of building plans and construct them as outlined. The general contractor may help perform the day-to-day building, or they may just hire workers and oversee all the work activities. In either case, the job of the general contractor is to see that your project gets built.

When you have a building project, ask for bids from various contractors. The bids tell you how much each will charge and what their scope of work will be. Once you have selected a bid, you sign a contract with that general contractor outlining the specifics of the project and the milestones during the project when they will receive payment installments. Once the contract is official, the general contractor will bring in their crew to begin construction. The contractor will manage the workers and subcontractors (anyone who doesn’t work directly for their company but that they need to outsource, like a marble installation pro), order all the materials, obtain work permits, and confirm that all the workers and subcontractors are completing their projects as planned. They typically handle all the payments to the workers and subcontractors, and send you invoice. For all these reasons, it’s also especially important to follow a few smart hiring practices when it comes to finding a general contractor.  If you are organized and competent to oversee construction projects, and are able to make sure everything is being built properly and meeting code, it’s possible you can be your own general contractor.  

How do architects work?

Architects may work for an architecture or engineering firm, they may work for a government organization, they can work for a construction company, or they may be self-employed (freelance). The U.S. Bureau of Labor Statistics explains that architects spend a large amount of their working time in the home or company office: meeting with clients; creating reports and architectural drawings; and working with other architects and engineers. When not in an office, an architect is often at the construction site either as part of the development of plans or to ensure building progress is following the blueprint.

When a client interacts with an architect, it is typically to have them design drawings for the construction of a house or a building. If you are a client who has hired a large architecture firm, there may be a team of people working on your design. But if you are working with a freelance architect or a smaller firm, one person (or a small group) will take your concept and translate it into an architectural blueprint that a builder can use to construct a house. The plans will lay out everything from the depth of the foundation to the materials to use to the type of metal to be used in the reinforcement. Once the plans have been created and handed off to the builder, the architect may remain on the project — depending on budget — and oversee progress.

How do architects charge for their services?

According to the U.S. Department of Labor, the median salary of an architect in 2016 was $76,930. This range included architects with every type of company as well as self-employed architects. Depending on the architect and whether they’re with a firm or independent, they may charge per hour or by the square foot, or they may charge a percentage of the total budget for a construction project. An hourly rate is typically used for smaller projects such as providing consultation, helping clients hone their concept before the design process begins, or drafting documents and plans. If an architect is working on an hourly basis on a larger project, there will usually be an agreed-upon cap on the number of hours they will work. For larger projects, such as new construction or total overhaul remodels, architects may charge a percentage of the total construction costs. The architect will usually set the percentage you will pay after the total cost of construction has been accounted for. Percentages can range within a firm depending on the extent of the services they’re providing. For example, a lower percentage of the total construction costs may include drafting and minimal consultation and guidance along the way, while a higher percentage could include on-site project management services with every detail attended to. Architects may also charge by the square footage of the project. The rate per square foot can vary depending on the individual’s training, the services they are providing, the complexity of the project, and other factors — such as obtaining permits. The national average cost to hire an architect is between $1,690 and $2,500.

How do you choose a commercial general contractor?

A commercial contractor provides similar services as a residential general contractor but specializes in working with large-scale projects for businesses, schools, nonprofits, governments and development firms. When researching commercial general contractors, review their portfolio of work and confirm they have ample experience working in the area you need. For example, if you are building a small strip mall, ask if the contractors have experience successfully incorporating all the needed elements such as a parking lot, meeting ADA requirements, accessing the proper permits, and completing work on time.

Once you’ve identified several qualified candidates, request bids for your project and then compare the scope of work with your needs and budget. Your commercial general contractor should oversee design, permitting, construction, materials purchase, and adherence to building code and zoning regulations, as well as sticking to an agreed-upon budget and schedule. It’s important to establish clear communication with your future commercial general contractor, as this will mean a smoother process for everyone. For all these reasons, it’s also especially important to follow a few smart hiring practices when it comes to finding a general contractor.

What do general contractors charge?

If you’re doing a home remodel, building a new home or embarking on a commercial building project, you’ll hire a general contractor. A general contractor is a professional who is qualified to oversee and execute construction projects. Each construction project is unique; even two duplicate homes built on lots next door to each other could have different construction costs due to factors like different excavation costs when building the foundation. Since each project is unique, many general contractors make bids on potential construction projects. These bids can then break down to a per square foot cost that encompasses the labor of all the workers needed for the job, materials, the scope of work, and any equipment needed. Materials and finishes make a major difference in your cost per square foot. For example, choosing standard kitchen tiles at $3 per square foot will result in a lower total project cost than imported marble tiles that cost $63 per square foot. Where you live will also affect how much general contractors charge, as labor and the cost to do business can cost less in many regions than in high-cost areas like New York or San Francisco. Here are some examples of average costs general contractors typically charge in various regions:

  • Home addition in San Francisco: $250-$270 per square foot.
  • New home construction in Knoxville, Tennessee: $100-$200 per square foot.
  • Kitchen remodel in Tennessee: $40-$80 per square foot, depending on finishes.
  • Bathroom remodel in Vancouver, Washington: $110-$170 per square foot.
