Emilco Construction LLC is an independent general contracting firm that not only delivers impeccable results but prioritizes its clients. We know just how stressful a new project can be. Overseeing a development can take a real toll on somebody, especially if they don’t have the right general contracting team by their side. It takes a lot of hard work, long hours and a particular care to details in order to accomplish and follow through on a vision. Although working on improving your home or business is exciting, we understand that success relies mainly on hiring the right crew for the job!

"Emile is a great contractor and I highly recommend him reservation to anyone looking to upgrade or do a home renovation project. He helped us renovate our primary bathroom (completely, down to the studs and completely changing the layout), created a main floor laundry room, and an extra bedroom. Emile provided a comprehensive estimate, which was accurate, and he finished the entire job within the agreed upon time frame within the estimate. His crew were complete professionals, polite, and did excellent work. We could not be happier with the results and our new spaces. The rooms are beautiful. He went above and beyond in all respects, even when I decided to make changes to the design along the way, he was able to roll with them and told me how much various options would cost and other pros and cons of those options (tiling the whole bathroom vs partial, heated floors or no, different types of fixtures, etc)."

High end architect specializing in making a house feel like home! I make people’s dream homes a reality. There is nothing more satisfying to me then improving the quality of life for my clients and giving them a house that they are able to make into their homes. I have been a licensed architect since 2015 and am currently registered in Rhode Island, Connecticut, New York, Maine and Massachusetts. With my NCARB certificate I am able, if necessary, to obtain reciprocal licensure throughout the country in a short time period. I am inspired by our local built environment, humble materials, classical building forms and traditional building details. I have a strong interest in the reinterpretation of classical building forms, blended with contemporary open floor plans. I have a stronger interest in helping to guide my clients to ways of improving the quality of their lives through adapting the built environment to meet their needs.

Custom Home Builders questions, answered by experts

In most cases, you should get an architect before you hire a builder. An architect will be the one to draw up formal plans for your project, including guidelines and even material lists for your builder to follow during construction. Many architects can even help you find builders, choose one for your project, and negotiate prices. Some are also willing to act as project managers throughout the process, working closely with a builder from start to finish.

Yes, a home builder should have a builder’s license and insurance. States have different requirements for builder’s licensing and certifications. Be sure to check our state licensing tool to review your local home builder licensing guidelines.

As you browse our pro listings, take note of the “Angi Certified” badge. Angi Certified businesses meet our standards for certification, which include:

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Remodeling a house is often less expensive than building a new house. You can expect to pay an average of $100 per square foot when you are remodeling. The cost to build a house averages about $150 per square foot. When remodeling, though, some rooms cost more than $100 per square foot and some cost less. Use a home renovation cost estimator to accurately estimate your remodeling costs.

Custom homes can take an average of 18 months to build, mainly due to the lengthy design process, and most projects take somewhere between 12 and 24 months. When you work with the right custom home builders near you, they can help you map the road ahead and understand what can speed up or delay the timeline. Choosing locally available materials, for example, can speed things up without losing that customized touch.

Framing is often the most expensive phase of building a house because it’s time-consuming and requires a lot of materials. It costs between $20,000 and $50,000 on average, depending on materials and labor costs. Before construction begins, it’s possible that purchasing land is the priciest step in the process. Some plots of land sell for $3,000, while others cost upwards of $150,000.
